Kirchhoff index of a non-complete wheel

In this work, we compute analitycally the Kirchhoff index and effective resistances of a weighted non–complete wheel that has been obtained by adding a vertex to a weighted cycle and some edges conveniently chosen. To this purpose we use the group inverse of the combinatorial LaplacianPostprint (author's final draft

Violation of Equivalence Principle and Solar Neutrinos

We have updated the analysis for the solution to the solar neutrino problem by the long-wavelength neutrino oscillations induced by a tiny breakdown of the weak equivalence principle of general relativity, and obtained a very good fit to all the solar neutrino data.Comment: 3 pages, 5 figures, uses espcrc2.sty, Talk presented by H.

Trust conceptualized as a corporate knowledge asset

To most individuals, "trust" can be viewed as a knowledge corporate asset that may add, or rest, value to the company. The role of knowledge in achieving a competitive advantage is becoming and increasingly important management issue in all business and non-business sectors. As such, our Throughput Modeling approach indicates how six different trust behaviors can be guided, how trust decision making can be improved and made defensible, and how special problems facing individuals can be dealt with via decision-making pathways leading to an action

Improving social corporate responsibility : the case of bullying behavior

This article highlights moral harassment at the workplace as a form of corruption in organizations. This form of corruption has cost organizations billions of dollars each year. A theoretical model is presented in this paper, which explains the main factors that affect bullying processes impact on organizations. Suggestions are provided in this paper, as tools to eliminate bullying within the workplace

Spiritual scriptures impact on six ethical models influencing organizational practices

Moral issues greet the business community constantly, confronting us with problems on handling accounting rules that can determine a company's future. We are bombarded with news regarding fraudulent activities in companies that mishandled accounting rules leading to undermining the confidence of customers, employees, suppliers, shareholders and the community. Dealing with ethical issues is often perplexing and without the benefits of a decision making model underlined by ethical positions we may be apt to repeat our old ways. Further, value and belief systems are often times absent and not connected to a decision making model in a useful manner. We argue for a modification of decision-making models that has been accepted in companies with stronger links with ethics and morality. With this aim we propose a return to the base values of Buddhism, Christianity, Hinduism, Judaism, and Islam by scriptures, underlying six dominant ethical approaches that drive practices in organizations

Revising the Solution of the Neutrino Oscillation Parameter Degeneracies at Neutrino Factories

In the context of neutrino factories, we review the solution of the degeneracies in the neutrino oscillation parameters. In particular, we have set limits to $\sin^2 2\theta_{13}$ in order to accomplish the unambiguous determination of $\theta_{23}$ and $\delta$. We have performed two different analysis. In the first, at a baseline of 3000 km, we simulate a measurement of the channels $\nu_e\to\nu_\mu$, $\nu_e\to\nu_\tau$ and $\bar{\nu}_\mu\to\bar{\nu}_\mu$, combined with their respective conjugate ones, with a muon energy of 50 GeV and a running time of five years. In the second, we merge the simulated data obtained at L=3000 km with the measurement of $\nu_e\to\nu_\mu$ channel at 7250 km, the so called 'magic baseline'. In both cases, we have studied the impact of varying the $\nu_\tau$ detector efficiency-mass product, $(\epsilon_{\nu_\tau}\times M_\tau)$, at 3000 km, keeping unchanged the $\nu_\mu$ detector mass and its efficiency. At L=3000 km, we found the existance of degenerate zones, that corresponds to values of $\theta_{13}$, which are equal or almost equal to the true ones. These zones are extremely difficult to discard, even when we increase the number of events. However, in the second scenario, this difficulty is overcomed, demostrating the relevance of the 'magic baseline'. From this scenario, the best limits of $\sin^2 2\theta_{13}$, reached at $3\sigma$, for $\sin^2 2\theta_{23}=0.95$, 0.975 and 0.99 are: 0.008, 0.015 and 0.045, respectively, obtained at $\delta=0$, and considering $(\epsilon_{\nu_\tau}\times M_\tau) \approx 125$, which is five times the initial efficiency-mass combination.Comment: 40 pages, 18 figures; added references, corrected typos, updated Eq (15c
