Evaluating the Impact and Determinants of Student Team Performance: Using LMS and CATME Data

Practitioners find it difficult to allocate grades to individual students based on their contributions to the team project. They often use classroom observation of teamwork and student peer evaluations to differentiate an individual’s grade from the group’s grade, which can be subjective and imprecise. We used objective data from student activity logs from our Learning Management System (LMS) as well as peer evaluations from the Comprehensive Assessment of Team Member Effectiveness’ website (CATME.org) to determine impacts on team grades and peer evaluations. We found that student activity in our LMS and conflict scores from peer evaluations (CATME) do correlate with grades, as do GPAs and credits earned at the College. We also found that, while the class was in session, we could use the data from the LMS and CATME scores to intervene with those teams that were experiencing conflict to help them learn productive conflict-resolution skills

Direct radiative capture of p-wave neutrons

The neutron direct radiative capture (DRC) process is investigated, highlighting the role of incident p-wave neutrons. A set of calculations is shown for the 12-C(n,gamma) process at incoming neutron energies up to 500 keV, a crucial region for astrophysics. The cross section for neutron capture leading to loosely bound s, p and d orbits of 13-C is well reproduced by the DRC model demonstrating the feasibility of using this reaction channel to study the properties of nuclear wave functions on and outside the nuclear surface. A sensitivity analysis of the results on the neutron-nucleus interaction is performed for incident s- as well as p-waves. It turned out that the DRC cross section for p-wave neutrons is insensitive to this interaction, contrary to the case of incident s-wave neutrons.

Antiferromagnetic Order of the Ru and Gd in Superconducting RuSr2GdCu2O8

Neutron diffraction has been used to study the magnetic order in RuSr{2}GdCu2O8. The Ru moments order antiferromagnetically at T{N}=136(2)K, coincident with the previously reported onset of ferromagnetism. Neighboring spins are antiparallel in all three directions, with a low T moment of 1.18(6) mu {B} along the c-axis. Our measurements put an upper limit of ~0.1 mu{B} to any net zero-field moment, with fields exceeding ~0.4T needed to induce a measurable magnetization. The Gd ions order independently at T{N}=2.50(2)K with the same spin configuration. PACS numbers: 74.72.Jt, 75.25.+z, 74.25.Ha, 75.30.KzComment: Four pages, Latex, 5 eps figure

Optimizing English and American Security Interests

Since the adoption of Uniform Commercial Code Article 9 in American jurisdictions in the 1960s, scholars have debated the desirability of the extraordinary priority given to secured creditors. Through a point-by-point comparison of English and American security interests, this article provides a new perspective on that long-running debate. The comparison reveals that security functions in strikingly similar manners in the two jurisdictions, while differing sharply in one crucial respect. In contrast to the absolute priority given secured creditors under American law, English law subordinates floating charges to administrative expenses, preferential creditors, and a prescribed share for unsecured creditors. Other, less important differences exist. The English and American filing systems and requirements generate secret liens in different ways with respect to different types of collateral. The English filing system is company-based, while the American filing system is name-based. The English system recognizes a public interest in the availability of filing system information, while the American system assumes that only debtors and their secured creditors have legitimate interests. English insolvency estates cannot grant lenders priority over pre-insolvency liens while American insolvency estates can. Lastly, the comparison reveals that English phoenix sales may provide a functional substitute for American cramdown – thus eliminating what some had considered an important difference between the two systems

Optimizing English and American Security Interests

The article discusses functional comparison of English and American security interests and suggests solutions of deception and incentives problems. It mentions that deception problem raise when debtors who have granted security interests appear to have wealth and incentives problem occurs when secured debt amount exceeds the value of the collateral. Security combined with mortgages, security interests, and liens which shows a relationship between collateral and monetary obligations

Organizational Culture of Small Retail Firms

A case study approach was used to examine organizational culture dimensions of small apparel retail firms located in small towns within the trading area of a regional shopping center. A long interview schedule was developed to obtain information from owners and employees. Content analysis of the qualitative responses revealed that 12 culture dimensions identified in previous research could be applied to the small firms. In addition, a dimension not clearly identified in previous research emerged in relation to influence of employees' family relationships on organizational culture. Suggestions for further research and application of the findings to management consultation are provided

Search for Magnetic Order in Superconducting RuSr2Eu1.2Ce0.8Cu2O10

Neutron diffraction, polarized neutron transmission, and small angle neutron scattering have been used to investigate the crystal structure and nature of the magnetic order in a polycrystalline sample of RuSr2Eu1.2Ce0.8Cu2O10. The sample was made with the Eu-153 (98.8%) isotope to reduce the high neutron absorption for the naturally occurring element. Full refinements of the crystal structure, space group I4/mmm, are reported. At low temperatures only a single magnetic peak is clearly observed in a relatively wide angular range. A sharp spin reorientation transition (SRT) is observed around 35 K, close to the superconducting transition temperature (Tc~40 K). Between the spin reorientation temperature and the Neel temperature of 59 K, additional magnetic reflections are observed. However, none of these can be simply indexed on the chemical unit cell, either as commensurate peaks or simple incommensurate magnetism, and the paucity of reflections at low T compels the conclusion that these magnetic Bragg peaks arise from an impurity phase. X-ray and neutron diffraction on the pressed pellet both show that the sample does not appear to contain substantial impurity phases, but it turns out that the magnetic impurity peaks exhibit strong preferred orientation with respect to the pellet orientation, while the primary phase does not. We have been unable to observe any magnetic order that can be identified with the ruthenate-cuprate system.Comment: 7 figures. Submitted to Phys. Rev.
