Leveraging Strength: The Pillars of American Grand Strategy in World War II

This article argues that U.S. leaders navigated their way through World War II challenges in several important ways. These included: sustaining a functional civil-military relationship; mobilizing inside a democratic, capitalist paradigm; leveraging the moral high ground ceded to them by their enemies; cultivating their ongoing relationship with the British, and embracing a kind of adaptability and resiliency that facilitated their ability to learn from mistakes and take advantage of their enemies’ mistakes.     

Variation of δ2H, δ18O & δ13C in crude palm oil from different regions in Malaysia: Potential of stable isotope signatures as a key traceability parameter

A total of 33 crude palm oil samples were randomly collected from different regions in Malaysia. Stable carbon isotopic composition (δ¹³C) was determined using Flash 2000 elemental analyzer while hydrogen and oxygen isotopic compositions (δ²H and δ¹⁸O) were analyzed by Thermo Finnigan TC/EA, wherein both instruments were coupled to an isotope ratio mass spectrometer. The bulk δ²H, δ¹⁸O and δ¹³C of the samples were analyzed by Hierarchical Cluster Analysis (HCA), Principal Component Analysis (PCA) and Orthogonal Partial Least Square-Discriminant Analysis (OPLS-DA). Unsupervised HCA and PCA methods have demonstrated that crude palm oil samples were grouped into clusters according to respective state. A predictive model was constructed by supervised OPLS-DA with good predictive power of 52.60%. Robustness of the predictive model was validated with overall accuracy of 71.43%. Blind test samples were correctly assigned to their respective cluster except for samples from southern region. δ¹⁸O was proposed as the promising discriminatory marker for discerning crude palm oil samples obtained from different regions. Stable isotopes profile was proven to be useful for origin traceability of crude palm oil samples at a narrower geographical area, i.e. based on regions in Malaysia. Predictive power and accuracy of the predictive model was expected to improve with the increase in sample size. Conclusively, the results in this study has fulfilled the main objective of this work where the simple approach of combining stable isotope analysis with chemometrics can be used to discriminate crude palm oil samples obtained from different regions in Malaysia. Overall, this study shows the feasibility of this approach to be used as a traceability assessment of crude palm oils.     

Choosing Healthplans All Together: a deliberative exercise for allocating limited health care resources

CHAT (Choosing Healthplans All Together) is an exercise in participatory decision making designed to engage the public in health care priority setting. Participants work individually and then in groups to distribute a limited number of pegs on a board as they select from a wide range of insurance options. Randomly distributed health events illustrate the consequences of insurance choices. In 1999-2000, the authors conducted fifty sessions of CHAT involving 592 residents of North Carolina. The exercise was rated highly regarding ease of use, informativeness, and enjoyment. Participants found the information believable and complete, thought the group decision-making process was fair, and were willing to abide by group decisions. CHAT holds promise as a tool to foster group deliberation, generate collective choices, and incorporate the preferences and values of consumers into allocation decisions. It can serve to inform and stimulate public dialogue about limited health care resources.
