This chapter discusses the second stage of the shipping crisis and the long-term effects that it evoked. It traces the crisis from the mid-seventies low, through a brief flourish in 1978, to the plummet in shipping trade in the early 1980s, ten years after the first oil price hike. It analyses the response within the industry to the depression, noting in particular the emergence of Asian flags of convenience (FOCs). It also analyses the situation in 1970s Norway, considering the heavy presence of Norway in the international shipping industry and their deadweight tonnage numbers to demonstrate the economic impact of the crisis on a national level.

Anxiety Depression

Background: Symptoms of anxiety, depression, and cancer-related fatigue are commonly associated with cancer. Cancer patients increasingly use complementary and alternative treatments, such as yoga, to cope with psychological and physical impairments. In the present article, long-term changes of anxiety, depression, and fatigue in cancer are examined 6 months after a yoga intervention. Method: We used an observational design based on a randomized controlled study in cancer patients with mixed diagnoses to evaluate long-term changes of symptoms of anxiety, depression, and fatigue 6 months after the end of yoga therapy. We measured anxiety symptoms with the Generalized Anxiety Disorder scale (GAD-7), depressive symptoms with the Patient Health Questionnaire–2 (PHQ-2), and fatigue with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire–Fatigue Scale (EORTC QLQ-FA13). Yoga therapy was provided in yoga classes of 60 minutes each once a week for 8 weeks in total. The exercises provided contained both body and breathing activities as well as meditation. Results: A total of 58 patients participated in the study. Six months after the end of yoga therapy, symptoms of anxiety, depression, and fatigue were significantly reduced compared with baseline. However, symptoms of anxiety and fatigue slightly increased during the follow-up period, whereas symptoms of depression remained stable. Conclusion: Our results are promising and support the integration of yoga interventions in supportive cancer treatment concepts but should be confirmed by randomized controlled trials. Long-term effects of yoga therapy on cancer patients should be the subject of further research.

Long Term Changes

Abstract. Recent climatic changes have the potential to severely alter river runoff, particularly in snow-dominated river basins. Effects of changing snow covers superimpose with changes in precipitation and anthropogenic modifications of the watershed and river network. In the attempt to identify and disentangle long-term effects of different mechanisms, we employ a set of analytical tools to extract long-term changes in river runoff at high resolution. We combine quantile sampling with moving average trend statistics and empirical mode decomposition and apply these tools to discharge data recorded along rivers with nival, pluvial and mixed flow regimes as well as temperature and precipitation data covering the time frame 1869–2016. With a focus on central Europe, we analyse the long-term impact of snow cover and precipitation changes along with their interaction with reservoir constructions. Our results show that runoff seasonality of snow-dominated rivers decreases. Runoff increases in winter and spring, while discharge decreases in summer and at the beginning of autumn. We attribute this redistribution of annual flow mainly to reservoir constructions in the Alpine ridge. During the course of the last century, large fractions of the Alpine rivers were dammed to produce hydropower. In recent decades, runoff changes induced by reservoir constructions seem to overlap with changes in snow cover. We suggest that Alpine signals propagate downstream and affect runoff far outside the Alpine area in river segments with mixed flow regimes. Furthermore, our results hint at more (intense) rainfall in recent decades. Detected increases in high discharge can be traced back to corresponding changes in precipitation.

AbstractFive principles determining movement in the housing market relating to tenure, social class and fertility status were suggested by Payne and Payne (1977) on the basis of a small-scale study in Aberdeen. Analysis of a large-scale nationally-representative survey containing full housing and maternity histories suggests that some of these principles require modification at the national level. For example, movement into and between tenures, although heavily influenced by demographic and socio-economic factors, is not as rigid as the Aberdeen study suggested. The interaction of social class, age at marriage and childbearing patterns is assessed. Finally, changes over time in these relationships and the long-term effects on final family size and tenure are discussed.

AbstractIn 2018 the IMO adopted the initial Strategy for the international shipping industry’s reduction of global greenhouse gas emissions towards achieving the goal set in the 2015 Paris Agreement. At this time the Strategy is no more than a preliminary structure to frame the measures that will need to be adopted for the short, medium and long terms. In the short term (2018–2023) a first suite of measures will be adopted, and the initial Strategy will be revised and adopted as changed in 2023 with proposed measures for the medium term (2023–2030) and long term (2030–2050 and beyond). New international standards, tools and best practices will be needed to supplement the existing energy efficiency management rules in the International Convention on the Prevention of Pollution from Ships, 1973/78. This article discusses the Strategy and the role of the IMO in leading the shipping industry on the road to decarbonization.

The Impact

Background: Disease-modifying therapies (DMTs) are used to treat people with relapsing-onset multiple sclerosis (ROMS), but our knowledge is largely limited to their short-term effects. Objective: To determine (1) the impact of national-level DMT subsidy policy on DMT use and health outcomes in people with MS (PwMS) and (2) the long-term effects of DMT on disability and quality of life (QoL; 5-level EQ-5D version (EQ-5D-5L) utility value). Methods: This observational cohort study compared Australian and New Zealand populations with different levels of DMT availability 10–20 years post-ROMS diagnosis. Between-country differences were assessed using standardised differences. Associations were assessed with multivariable linear regression models. Results: We recruited 328 Australians and 256 New Zealanders. The Australian cohort had longer DMT treatment duration, greater proportion of disease course treated and shorter duration between diagnosis and starting DMT. The Australian cohort had lower median Expanded Disability Status Scale (EDSS) (3.5 vs 4.0) and Multiple Sclerosis Severity Score (MSSS) (3.05 vs 3.71) and higher QoL (0.71 vs 0.65). In multivariable models, between-country differences in disability and QoL were largely attributed to differential use of DMT. Conclusions: This study provides evidence for the impact of national-level DMT policy on disability outcomes in PwMS. Where DMTs are more accessible, PwMS experienced less disability progression and improved QoL 10–20 years post-diagnosis.

Self-correction for crowdsourced tasks is a two-stage setting that allows a crowd worker to review the task results of other workers; the worker is then given a chance to update their results according to the review.Self-correction was proposed as a complementary approach to statistical algorithms, in which workers independently perform the same task.It can provide higher-quality results with low additional costs. However, thus far, the effects have only been demonstrated in simulations, and empirical evaluations are required.In addition, as self-correction provides feedback to workers, an interesting question arises: whether perceptual learning is observed in self-correction tasks.This paper reports our experimental results on self-corrections with a real-world crowdsourcing service.We found that:(1) Self-correction is effective for making workers reconsider their judgments.(2) Self-correction is effective more if workers are shown the task results of higher-quality workers during the second stage.(3) A perceptual learning effect is observed in some cases. Self-correction can provide feedback that shows workers how to provide high-quality answers in future tasks.(4) A Perceptual learning effect is observed, particularly with workers who moderately change answers in the second stage. This suggests that we can measure the learning potential of workers.These findings imply that requesters/crowdsourcing services can construct a positive loop for improved task results by the self-correction approach.However, (5) no long-term effects of the self-correction task were transferred to other similar tasks in two different settings.

Abstract Background China has rich and vast genetic resources of indigenous pig breeds. Currently, great attention is paid to either crossbreeding or conservation of these indigenous pig breeds, and insufficient attention is paid to the combination of conservation and breeding along with their long-term effects on genetic diversity. The genetic diversity of livestock is essential to increase productivity and respond to future challenges such as climate change. The genetic stability and product consistency of these indigenous pig breeds should be focused on and further improved. Therefore, the objective of this study is to compare the long-term effects of using conventional conservation and optimal contribution selection methods on genetic gain and genetic diversity. Results A total of 11 different methods including conventional conservation and optimal contribution selection methods were investigated using stochastic simulations with a population size of 600 animals in each generation. Each scenario was run for 20 generations and 100 replicates. The long-term effects of using these methods were evaluated in terms of rate of genetic gain, rate of true inbreeding based on genome-wide identity-by-descient (IBD) markers and various genetic diversity metrices such as expected heterozygosity (He). The results indicated that the rates of true inbreeding in these conventional conservation methods were maintained at around 0.01. The optimal contribution selection methods based either on the pedigree (POCS) or genome (GOCS) information showed more genetic gain than conventional methods, and POCS achieved the largest gentic gain. Furthermore, the effect of using GOCS methods on most of the genetic diversity metrics was slightly better than the conventional conservation methods when the the rate of true inbreeding was the same, but this also required more sires used in OCS methods. According to the rate of true inbreeding, there was no significant difference among these conventional methods. Conclusion In conclusion, there is no significant difference in different ways of selecting sows on inbreeding when we use different conventional conservation methods. Compared with conventional methods, POCS method could achieve the most genetic gain. However, GOCS methods can not only achieve higher genetic gain, but also maintain a relatively high level of genetic diversity. Therefore, GOCS is a better choice if we want to combine conservation and breeding in actual production in the Chinese national-level conservation farms.

Long Term Changes

Soil carbon (C) stocks under permanent New Zealand pastures vary with slope and aspect due to differences in primary production, animal behaviour and nutrient return. An existing nutrient transfer model was extended using a web-based, general-purpose modelling tool to simulate long-term changes in soil phosphorus (P) and C in hill country under contrasting fertiliser and sheep stocking regimes. Three self-contained farmlets were examined: no P applied; 125 kg single superphosphate (SSP)/ha/year; and 375 kg SSP/ha/year, since 1980. The refined spatial model was able to simulate P and C distribution with varying slopes and aspects. For example, the mean annual changes in soil P and C were greater on low slopes and eastern aspects than on the other two slope and aspect positions, consistent with observed changes in these nutrients. However, the model overestimated changes in soil C, which highlighted both gaps in current knowledge and key factors influencing change in soil C stocks. Understanding the spatial patterns of soil C across the landscape will be critical in the design of soil C monitoring regimes, should soil C stocks be considered at a national level as a sink or source of CO2 emissions.
