Wetland restoration design modifications to mitigate climate change impacts at Delaware Water Gap National Recreation Area: A case study report

Historic temperature and precipitation trends, and their projected climate change effects, were used to inform the development of wetland design tactics to restore a 30-acre degraded wetland at Delaware Water Gap National Recreation Area. The adverse effects of climate change to be addressed in the restoration design include increasing average daily air temperatures, rising stream and groundwater temperatures, increasing stream erosion, increasing precipitation, and increasing lake evaporation. Specific actions or tactics were developed that provide prescriptive direction in how restoration strategies can be translated to changes in on-the-ground conditions. Traditional on-the-ground tactics are described, along with modifications to the traditional tactics that should facilitate adaptation and increase the system’s capacity to survive adverse effects of climate change

Cold War Revival: Neoconservatives and Historical Memory in the War on Terror

Throughout the cold war, neoconservative intellectuals argued that the United States is an inherently virtuous nation engaged a permanent struggle against enemies at home as well as abroad. This essay addresses the ways that contemporary neoconservative voices have tried to revive the narrative of struggle, in part by claiming that the war on terror must be understood as a “present danger” that resembled the cold war. According to these commentators, a victorious strain of American foreign policy was born during the early years of the cold war. After three decades of setbacks and faltering national “will,” these principles were supposedly were reanimated by Ronald Reagan, who eventually carried the nation to triumph. By arguing that Americans are capable of restoring abandoned paths to victory, neoconservatives insist that the lessons of the cold war must be revived and applied to the struggle against radical Islam

Cervical range of motion in school age rugby union players: A cross sectional study

Objectives: Provide normative values for cervical range of motion and describe trends in school age rugby union players. Design: Cross-sectional study. Setting: National 3 level club. Participants: 59 school age rugby union players across under 8 (n = 8), under 9 (n = 9), under 10 (n = 15), under 13 (n = 13)and under 15 (n = 15)categories. Main outcome measures: Cervical range of motion using a cervical range of motion device (CROM)to determine values for active range of motion. Results: This study established mean ranges of motion for each age group. Pooled mean ranges with standard deviations for each direction were, flexion 66° (±11), extension 73° (±17), left rotation 69° (±9), right rotation 74° (±10), left lateral flexion 53° (±10)and right lateral flexion 49° (±12). No statistically significant differences were observed between the age groups, however, downward trends in lateral flexion were observed as age increased. School age rugby players had greater range of motion than senior playing counterparts. Conclusions: No statistically significant differences in ranges of motion were observed between the age groups of under 8 through to under 15. However, downward trends in some ranges of motion highlight the need for age specific monitoring for potential adaptations to continued playing and comparison to age matched non-rugby players. Inclusion of other risk factors such as head re-positioning sense should also be evaluated to help guide injury risk reduction strategies.</p

Lin-Kernighan Heuristic Adaptations for the Generalized Traveling Salesman Problem

The Lin-Kernighan heuristic is known to be one of the most successful heuristics for the Traveling Salesman Problem (TSP). It has also proven its efficiency in application to some other problems. In this paper we discuss possible adaptations of TSP heuristics for the Generalized Traveling Salesman Problem (GTSP) and focus on the case of the Lin-Kernighan algorithm. At first, we provide an easy-to-understand description of the original Lin-Kernighan heuristic. Then we propose several adaptations, both trivial and complicated. Finally, we conduct a fair competition between all the variations of the Lin-Kernighan adaptation and some other GTSP heuristics. It appears that our adaptation of the Lin-Kernighan algorithm for the GTSP reproduces the success of the original heuristic. Different variations of our adaptation outperform all other heuristics in a wide range of trade-offs between solution quality and running time, making Lin-Kernighan the state-of-the-art GTSP local search.Comment: 25 page
