Glass Ceilings & Leaky Pipelines: Gender Disparity in the Casino Industry

While women account for over half the hospitality workforce there is a gap in leadership positions. This study evaluates 10,950 management positions in 972 United States commercial and Native American casinos, as of December 2016. The results show women hold 35.5% of manager and above positions. Women lead in departments such as human resources, public relations, and sales and events, but lag in casino operations management. This demonstrates horizontal occupational segregation. The results also indicate women represent 46.7% of managers, but significantly less of executive leadership. Women held only 19.4% of owner, president, and chief positions. This suggests vertical occupational segregation or a potential glass ceiling. Gaps in vertical leadership occur across individual departments as well

Advanced materials for space nuclear power systems

The overall philosophy of the research was to develop and characterize new high temperature power conversion and radiator materials and to provide spacecraft designers with material selection options and design information. Research on three candidate materials (carbide strengthened niobium alloy PWC-11 for fuel cladding, graphite fiber reinforced copper matrix composites for heat rejection fins, and tungsten fiber reinforced niobium matrix composites for fuel containment and structural supports considered for space power system applications is discussed. Each of these types of materials offers unique advantages for space power applications

Regularities

The neoclassical q-theory is a good start to understand the cross section of returns. Under constant return to scale, stock returns equal levered investment returns that are tied directly with characteristics. This equation generates the relations of average returns with book-to-market, investment, and earnings surprises. We estimate the model by minimizing the differences between average stock returns and average levered investment returns via GMM. Our model captures well the average returns of portfolios sorted on capital investment and on size and book-to-market, including the small-stock value premium. Our model is also partially successful in capturing the post-earnings-announcement drift and its higher magnitude in small firms.

Classical many-body time crystals

Discrete time crystals are a many-body state of matter where the extensive system's dynamics are slower than the forces acting on it. Nowadays, there is a growing debate regarding the specific properties required to demonstrate such a many-body state, alongside several experimental realizations. In this work, we provide a simple and pedagogical framework by which to obtain many-body time crystals using parametrically coupled resonators. In our analysis, we use classical period-doubling bifurcation theory and present a clear distinction between single-mode time-translation symmetry breaking and a situation where an extensive number of degrees of freedom undergo the transition. We experimentally demonstrate this paradigm using coupled mechanical oscillators, thus providing a clear route for time crystals realizations in real materials.Comment: 23 pages, 5 figures, comments are welcom

E-democracy: exploring the current stage of e-government

Governments around the world have been pressured to implement e-Government programs in order to improve the government-citizen dialogue. The authors of this article review prior literature on such efforts to find if they lead to increased democratic participation ("e-Democracy") for the affected citizens, with a focus on the key concepts of transparency, openness, and engagement. The authors find that such efforts are a starting point toward e-Democracy, but the journey is far from complete

Let Ghosts Be Ghosts

(Excerpt) Part I of this Note discusses the rise of pro se status in civil matters, specifically in immigration proceedings, and how courts and the legal community have responded with limited scope representation, including ghostwriting. Part II discusses in detail the controversy surrounding ghostwriting. It also illustrates how ghostwriting is, fortunately, beginning to gain acceptance. Lastly, Part III urges the acceptance of ghostwriting in immigration proceedings. It explains why ghostwriting is essential to immigrants and how the arguments put forth against the practice are not applicable to immigration proceedings

Tutorials for software : a comparison of the Appleworks software tutorial with pre-entered data and an experimental tutorial with user entered data

The attention directed toward computer software research has been sparse which is quite evident in particular facets such as learning methods, specifically towards tutorials. Some authors have identified various important issues which include cognitive factors, reduction of presentation of superfluous information, and the importance of interaction with software and hardware. The present . study examined two tutorials which were similar except in their level of required user behaviors. Tutorial A required only user manipulation of disk stored data. Tutorial B required the user to enter the data into the computer, design the screen format, and then to manipulate it. It was predicted that the extra task of entering data and designing the screen format would provoke more positive scores for Tutorial B as measured by two independent questionnaires, would require fewer requests for assistance than for those using Tutorial A, and require a comparative duration period to complete. The results obtained supported all hypotheses except for the duration period which took longer for Tutorial B. The implication is that there should be development of improved Tutorial options utilizing research based methods such as these presented
