Report of Governor Johan Rising, 1655, on New Sweden
No full textGovernor Johan Rising reports to the Swedish government and royalty on the status of New Sweden (present-day New Jersey). He also reports on other Swedish colonies in the area. He asks that single women and skilled tradesmen be sent to the colonies. Rising also reports that attacks from neighboring Indian tribes are increasing. He has found some protection by forming an alliance with English settlers, but the cost is high, and his colony owes the English money and supplies. Rising asks that Sweden send them money so that they can pay off their debts, build ships that would establish a trading dominance with the West Indies, and cultivate land and crops to gain more profit. Reports from New World governors were sent back to their native countries via ships. Rising sent this report in June of 1655, but Sweden did not recieve the report until November of 1655.

Analysis Choices Impact Movement Evaluation: A Multi-Aspect Inferential Method Applied to Kinematic Curves of Vertical Hops in Knee-Injured and Asymptomatic Persons
No full textThree-dimensional human motion analysis provides in-depth understanding in order to optimize sports performance or rehabilitation following disease or injury. Recent developments of statistical methods for functional data allow for novel ways to analyze often complex biomechanical data. Even so, for such methods as well as for traditional well-established statistical methods, the interpretations of the results may be influenced by analysis choices made prior to the analysis. We evaluated the consequences of three such choices when comparing one-leg vertical hop (OLVH) performance in individuals who had ruptured their anterior cruciate ligament (ACL), to that of asymptomatic controls, and also athletes. Kinematic data were analyzed using a statistical approach for functional data, targeting entire curve data. This was done not only for one joint at a time but also for multiple lower limb joints and movement planes simultaneously using a multi-aspect methodology, testing for group differences while also accounting for covariates. We present the results of when an individual representative curve out of three available was either: (1) a mean curve (Mean), (2) a curve from the highest hop (Max), or (3) a curve describing the variability (Var), as a representation of performance stability. We also evaluated choice of sample leg comparison; e.g., ACL-injured leg compared to either the dominant or non-dominant leg of asymptomatic groups. Finally, we explored potential outcome effects of different combinations of included joints. There were slightly more pronounced group differences when using Mean compared to Max, while the specifics of the observed differences depended on the outcome variable. For Var there were less significant group differences. Generally, there were more disparities throughout the hop movement when comparing the injured leg to the dominant leg of controls, resulting in e.g., group differences for trunk and ankle kinematics, for both Mean and Max. When the injured leg was instead compared to the non-dominant leg of controls, there were trunk, hip and knee joint differences. For a more stringent comparison, we suggest considering to compare the injured leg to the non-dominant leg. Finally, the multiple-joint analyses were coherent with the single-joint analyses. The direct effects of analysis choices can be explored interactively by the reader in the Supplementary Material. To summarize, the choices definitively have an impact on the interpretation of a hop test results commonly used in rehabilitation following knee injuries. We therefore strongly recommend well-documented methodological analysis choices with regards to comparisons and representative values of the measures of interests
Report of Governor Johan Printz, 1647, on New Sweden
No full textGovern Johan Printz, the governor of New Sweden (later to become New Jersey), reports on the status of the colony and the settlers. Many freemen have arrived to settle in New Sweden, but the criminals and military men who were conscripted to the colony want to return to Sweden. Of the freemen, very few are skilled, so Governor Printz asks that blacksmiths, tanners, tailors, carpenters, and butchers be sent to the colony. Additionally, he asks for single women. Printz also reports on two new Swedish colonies that have been established along the Delaware River. However, Dutch settlers have become very aggressive by re-purchasing land from the Indians that the Swedish had already bought. They are also interrupting trade between the Swedes and the Indians, as well as instigating the Indians to attack the Swedes. Printz directed the construction of some storage houses along common trade routes to win back trade from the Indians. However, fighting has erupted between different Native tribes as each tries to establish dominance in trading with the colonies.

Relation of the surrender of New Sweden, by Governor Johan Clason Rising, 1655
No full textGovernor Johan Rising of New Sweden reports to Sweden on the August 1655 Dutch attack on New Sweden's Fort Christina. The Dutch traveled from New Amsterdam (present-day New York) and easily captured a New Sweden outpost. Rising sent men to the outpost to fend of the Dutch, but the Dutch defeated them and took them as prisoners, leaving Fort Christina without fighting men and supplies. The Dutch then put the Fort under seige. A few days later, Rising surrendered the Fort. He and the Swedish colonists were ordered to either return to Sweden, or to remain in the New World in service to the Dutch.

Experiences and challenges from developing cyber-physical systems in industry-academia collaboration
No full textCyber-physical systems (CPSs) are increasing in developmental complexity. Several emerging technologies, such as Model-based engineering, DevOps, and Artificial intelligence, are expected to alleviate the associated complexity by introducing more advanced capabilities. The AIDOaRt research project investigates how the aforementioned technologies can assist in developing complex CPSs in various industrial use cases. In this paper, we discuss the experiences of industry and academia collaborating to improve the development of complex CPSs through the experiences in the research project. In particular, the paper presents the results of two working groups that examined the challenges of developing complex CPSs from an industrial and academic perspective when considering the previously mentioned technologies. We present five identified challenge areas from developing complex CPSs and discuss them from the perspective of industry and academia: data, modeling, requirements engineering, continuous software and system engineering, as well as intelligence and automation. Furthermore, we highlight practical experience in collaboration from the project via two explicit use cases and connect them to the challenge areas. Finally, we discuss some lessons learned through the collaborations, which might foster future collaborative efforts

The social challenges of low carbon development
No full textThis book explores the social implications and challenges of low-carbon development. The argument of the book is that a broad understanding of low-carbon development is essential for mitigating climate change and enabling development in a carbon-constrained world, but there are risks that low-carbon development might come at a price that is both social and economic. These risks need to be carefully assessed and reduced. The main aim of the book is to explore, critically analyse and propose different ways of understanding low-carbon development from a social perspective in both developed and developing countries. The author uses concepts such as low-carbon development, social policy, sustainable development and environmental justice to understand the social implications of low-carbon development projects. The book first elaborates the need to understand the social issues and challenges of low-carbon development in both developed and developing countries. It then discusses five contemporary challenges of low-carbon development: * the social consequences of Chinese hydropower dams in the Mekong region; * the cost of the transition to renewable energies such as wind energy in Germany; * the challenges of carbon offsetting in Brazil; * the nexus of fuel-inefficient housing and fuel poverty in England; * solar power for refugees in Africa. The book fills a crucial gap for researchers, postgraduates, practitioners and policy-makers in the fields of climate change, development and social policy.
