Stop taxing happiness : a new perspective on progressive taxation

The development of taxation law and policy has been driven largely by economic considerations and economic theory. Underlying this is the assumption that money is important to human well-being and is in fact the most important thing in this regard. Recent empirical studies of human well-being disprove this assumption. Money has only a limited bearing on happiness. It follows that economic arguments that have long shaped taxation law and policy should be discarded in preference for recent learning concerning what really matters to people. The results of the recent studies have significant implications for the manner in which we should raise tax. We argue that for income under approximately $20,000 the rate should be 0 to 5 per cent. For income between $20,000 to $50,000 the rate should be about 15 per cent. Incomes beyond this level should taxed at approximately 75 per cent. There is no reason to have further rate differentials.

Sleep quality and depression during pregnancy: a prospective study

For the first time, the relationship between depressive symptoms and sleep quality was explored prospectively during pregnancy. Participants (n = 273) completed the Pittsburgh Sleep Quality Index and Beck Depression Inventory at three 8-week intervals, starting from 15–23 weeks gestation. In addition to sleep quality and depression remaining relatively stable during pregnancy, findings revealed that sleep quality earlier in pregnancy predicted higher levels of depressive symptoms at later stage in pregnancy (after controlling for prior depression levels). In contrast, there was no evidence to suggest that depressive symptoms earlier in pregnancy impacted on sleep quality later on. Given that depressive symptomatology can lead to major depression and given the prevalence of pre- and postnatal depression, our findings suggest that screening for sleep problems during pregnancy may be of clinical significance.

Assessing Sleep during Pregnancy - a study across two time points examining the pittsburg sleep quality index and associations with depressive symptoms

Background and Purpose: Sleep quality seems to be an antecedent to depressive symptoms during pregnancy. We sought to 1) examine the psychometrics of the Pittsburgh Sleep Quality Index (PSQI) in pregnancy; 2) examine whether sleep quality predicted increases in depressive symptoms; and 3) compare PSQI scores across 3 or 2 levels of depressive symptoms.

Methods: Each of the 252 participants completed the Beck Depression Inventory (short form) and a sleep quality measure at mid and late pregnancy.

Results: PSQI total scores showed good internal consistency and construct validity. An improved model of the internal structure of the PSQI in pregnancy was found with 1 factor labeled Sleep Efficiency, a second labeled Night and Daytime Disturbances, and an Overall Sleep Quality component associated with, but separate from, both of these 2 factors. Although PSQI scores showed moderate stability over time, sleep disturbance scores increased in late pregnancy. Importantly, PSQI prospectively predicted increases in depressive symptoms.

Conclusions: Findings suggest that the PSQI is useful in pregnancy research. Findings also support the idea that sleep problems are prospective risk factors for increases in depressive symptoms during pregnancy. Practitioners are advised to screen for sleep quality during early pregnancy.

Examination of a multi-factorial model of body-related experiences during pregnancy : the relationships among physical symptoms, sleep quality, depression, self-esteem, and negative body attitudes

The aim of this cross-sectional study was to investigate relationships among women's body attitudes, physical symptoms, self-esteem, depression, and sleep quality during pregnancy. Pregnant women (N = 215) at 15–25 weeks gestation completed a questionnaire including four body image subscales assessing self-reported feeling fat, attractiveness, strength/fitness, and salience of weight and shape. Women reported on 29 pregnancy-related physical complaints, and completed the Beck Depression Inventory, Rosenberg Self-esteem Scale, and Pittsburgh Sleep Quality Index. In regressions, controlling for retrospective reports of body image, more frequent and intense physical symptoms were related to viewing the self as less strong/fit, and to poorer sleep quality and more depressive symptoms. In a multi-factorial model extending previous research, paths were found from sleep quality to depressive symptoms to self-esteem; self-esteem was found to be a mediator associated with lower scores on feeling fat and salience of weight and shape, and on higher perceived attractiveness.

The dark ride : The history of the thematic ride as a unique model for new media and cinematic installation

This research examines the translation of the visual language of cinema into a spatial experience. An investigation into early moving images reveals the role that amusement parks played in exploring narratives using architectural spaces. The exegesis will address the history of entertainments, in particular the ‘dark ride’, which have an emphasis on narrative over and above effect.

Extensive field research was undertaken including historical sites across the east coast of the US, in search of new approaches to new media. Over twenty key popular entertainments were experienced first-hand, from Coney Island’s legendary ‘Spookarama’, to the earliest dark ride in operation, ‘The Old Mill’ at Kennywood in Pittsburgh.

New trends in the making of international commercial law

This paper analyzes trends in the making of international commercial law including the impetus for generating conventions, the growth of regional conventions, and soft law.There has never been a better time to be an international commercial law scholar. After decades of being held hostage to state-centered ideas, international commercial law has finally broken through to become more solution oriented. Increasingly, nation states are becoming less important in the creation of international commercial law with the growth of regional organizations, non-state actors, and international arbitration. This is spurred on by the march of globalization and the need for international commercial law. The term "harmonization will be used as a surrogate to discuss the creation of international commercial law as it is the primary means by which international commercial law is created. This article seeks to explore two preponderant trends that have become visible in the making of international commercial law. In Part I, I shall describe the background. In Parts II and III, I will highlight the growing role of regional endeavors at harmonization, and the rise of non-binding instruments.

The dawn of the dark ride at the amusement park

Plotting the evolution of the dark amusement park ride is important in understanding the hybrid nature of the entertainment industry we see today. This paper looks specifically at two amusement park rides and shows how they form an important landmark in the evolution of immersive technology. The investigation focuses on Pittsburgh's Old Mill Ride (1905) in the USA and Blackpool's River Caves (1907) in the UK. Two rides which were the first of their kind and represent the solidification of technical and conceptual approaches being developed on both sides of the pacific. Whilst these rides are mentioned in isolation in a small number of academic texts, their connection and importance in the timeline of popular media has been overlooked. A combination of field and historical research examines how these rides were unique and influenced other media that preceded them.

Subjective sleep impairment in adults with type 1 or type 2 diabetes: results from Diabetes MILES - the Netherlands

AIMS: Despite growing recognition of the impact of sleep on diabetes, a clear profile of people with diabetes regarding subjective sleep impairment has yet to be established. This study examines: (1) subjective sleep characteristics in adults with type 1 and type 2 diabetes; (2) the relationship of poor subjective sleep quality with glycaemic control, self-care and daytime functioning; (3) possible risk markers for poor sleep quality. METHODS: In a cross-sectional study, Dutch adults with type 1 (n=267) or type 2 diabetes (n=361) completed an online survey, including the Pittsburgh Sleep Quality Index (PSQI), socio-demographic, clinical, self-care and psychological measures. RESULTS: Poor sleep quality (PSQI-score >5) was reported by 31% of adults with type 1 and 42% of adults with type 2 diabetes. Participants with good and poor sleep quality did not differ in self-reported HbA1c or the frequency of meeting lifestyle recommendations. Poor sleep quality was related to a higher self-care burden and higher levels of daytime sleepiness, fatigue, depressive and anxiety symptoms, and diabetes-specific distress. In multivariable logistic regression analyses examining risk markers, poor sleep quality was associated with depressive symptoms in adults with type 1 (OR=1.39, 95% CI 1.25-1.54) and type 2 diabetes (OR=1.31, 1.16-1.47), and with being female in those with type 2 diabetes (OR=2.72, 1.42-5.20). CONCLUSIONS: Poor subjective sleep quality is prevalent both in adults with type 1 and type 2 diabetes, and is related to poor daytime functioning and higher self-care burden. The temporal relation with depression and merits of therapy should be explored.
