AdS/CFT correspondence is adopted and fermion masses are modeled as analogues of Weyl curvature states, which occur by hypothesis when closed spin-2 strings sweep out closed world tubes. Admissible curvature states are established by gauge invariance and fundamental mass is attributed to admissible curvature. A consequent spectrum of masses forms an SU(3) symmetry that is invariant under appropriate realizations of the SUGRA GUT interaction. Finally the spin-h/2 nature of the masses that are attributed to curvature emerges as a necessary condition for the relevant SUGRA GUT realizations. Calibration of the proposed model reveals a spectrum of fermion masses that corresponds approximately to observation. Moreover, the proposed model predicts a new quark that is characterized by I3 = -1/2 and by a mass of about 30 GeV/c2.
Anecdotal evidence suggests that there is a stark contrast between the project management tools and techniques taught in schools and those actually used in industrial settings. This exploratory study provides evidence of those differences in the form of qualitative data collected from project managers in the information technology areas of major firms from the banking, cosmetics, and electronics manufacturing industries. Evidence suggests that there is a significant variation in which the formal project management processes taught in traditional project management curricula are used, if any. The study explores the reasons behind these differences and suggests possible approaches to ease the strain for new hires and current employees.
Index funds are those funds that seek to
track the returns of the market benchmarks, such as the Wilshire 5000 and S
& P 500 Index. Although many fund managers claim to outperform the market
through experience and forecasting, a combination of cost savings,
diversification and longevity had helped to keep index funds’ returns float to
the top rankings. By using simple quantitative evidence, this paper explained
in plain language how investing in index funds can help investors get ahead of
the majority of fund managers in terms of consistent returns. The paper equally
explained why index funds are likely to continue to outperform not only the
average mutual funds but also the conventional stocks and bonds, both in the
bull and bear markets.
Language is about
passing on meanings. This implies a speaker’s level of proficiency and fluency
and a level of comprehension by the listener. English, a widely used medium,
has been deeply researched on in how it is used by non-native speakers to
inform native speakers, and by native speakers to inform non-native speakers.
However, little research is done on non-native speakers using it to inform
non-native speakers. This article draws on the research done with university
students carrying out their practicum using English as the medium suggested in
the government policy. Their voices indicate that despite their limited
proficiency and fluency, linguistic choices are based on their beliefs.
Therefore, utterances should not be judged on the basis of proficiency and
fluency but on beliefs which are shaped by their culture, policies and
This article highlights multiple ways in which kindergarten through
twelfth grade (K-12) school leaders can work collaboratively with education
stakeholders in elementary and secondary school settings to develop distributed
leadership environments in their school communities to address the persistent
and often seemingly intractable teaching and learning improvement dilemma challenges
that plague many schools today. Insights gleaned from a brief examination of
the distributed leadership attributes of one communal cultural tradition are
utilized as the basis for generating some creative strategies for nurturing
distributed leadership environments in school settings. These strategies may be
useful to elementary and secondary school leaders working in a variety of
educational environments who are interested in broadening their collaborative
teaming and instructional support networks and energizing their school
turnaround and improvement efforts.
