Engaging China – Reflections from the EU’s and ASEAN’s Responses. EU Centre Background Brief, 3rd January 2019
No full textChina’s rise as a global economic and trading power has taken on a new significance for the Asia-Pacific region as well as the western world in light of USA’s increasing protectionism under the Trump administration. This brief will explore how regional organizations like the Association for South East Asian Nations (ASEAN) and the European Union (EU) as well as their member states respond to the rise of China and its increasing assertiveness in projecting its power and protecting its interests globally. China’s geographical proximity to South East Asia and the power competition between China and USA are important factors that shape the responses of ASEAN nations. This brief looks at the “hedging” and “bandwagoning” strategy employed by ASEAN member states against China. On the other hand, being a more unified actor than ASEAN and a central pillar for a rule-based multilateral world order, the EU hopes to constructively manage its internal differences while engaging China in its reform process. Upon closer look, the author finds that the EU, like ASEAN, is challenged by an unpredictable and unilateral America First under Trump, and an increasingly assertive China. To manage the rising tensions and uncertainties, both regional organisations need to be more cohesive and united. They should also work more closely together to uphold a rule-based multilateral order

Drawing the Line: An Exploration of How Lay People Construct Child Neglect
No full textThis thesis uses a Foucauldian approach to explore how lay people construct child neglect in England. The concept of child neglect developed after the Industrial Revolution in conjunction with the construction of ‘normal’ childhood. Both depend on developmental models of childhood produced by psy-complex discourse. However, the knowledge producing the ‘normal’ family and the disciplinary institutions producing and protecting the ‘normal’ childhood have been challenged by late modernity, with a potential impact on what can be considered ‘abnormal’ and therefore neglectful.
Recent years have seen an increasing professional and political focus on both the importance of child neglect, and the role of lay people in child protection – ‘everybody’s business’. It is unclear how lay people construct child neglect, a category that properly results from political and moral choices made by society. To analyse how lay people construct child neglect, data was collected from focus group discussions between 46 self-defined ‘lay’ people.
Children were constructed as having developmental needs during childhood, which, if unmet, could cause long term problems for child and society. Four clusters of needs were identified: physical, emotional, training and supervisory. If these needs were unmet, children could be seen as Deprived, Unloved, Uncontrolled or Escaping. However, this did not mean they were positioned as neglected. Neglect required some abnormal adult/parent behaviour. The normal parent was non-neglectful although sometimes temporarily Overburdened, the abnormal parent was neglectful, categorised as Clueless, Underinvested or Unsuitable. Lay people were constructed as having a responsibility to support parents and families within their midst. However the forces of late modernity, particularly globalisation, challenged the normal/abnormal family binary, leaving lay people unclear about where society and/or child protection professionals draw the line between normal and neglectful childhoods. The implications of these constructions for children, parents, state, professionals and lay people are examined and recommendations made

Abstract
The purpose of the present study was to investigate the effect of long-term Wai Tan Kung exercise on heart rate (HR), energy expenditure, oxygen uptake (VO2), ventilation (VE), heart rate variability and blood pressure. Two different groups of older adults were recruited. One group subjects (n =16; 65.0 ± 4.2 yrs, 163.3 ± 7.3 cm, 63.3 ± 7.3 kg) had been participated at least 10 years of regular Wai Tan Kung exercise (long-term group, LTG), and the other (n = 16; 59.0 ± 3.7 yrs, 162.0 ± 3.9 cm, 65.7 ± 3.6 kg) had been participated as same exercise as LTG but less than one year (short-term group, STG). The results of this study showed that there were significant differences (p < .05) in rest systolic pressure, and HR, energy expenditure, VO2, VE, high frequency power (HFP) and low frequency power (LFP) during exercise between LTG and STG (p < .05). LTG subjects had a significant lower in rest heart rate and blood pressure (p < .05) than STG subjects, and the former also reached higher (p < .05) exercise intensities during exercise testing than the latter. Moreover, there were significant higher heart rate, VO2 and VE during exercise testing for LTG than STG, suggesting that LTG subjects had higher metabolic rate. Additionally, LTG had a higher HFP than STG, suggesting that there was a significant increase in parasympathetic division of autonomic nervous activity during exercise testing for LTG than STG, indicating LTG subjects may prevent from coronary artery disease and improve functions of the heart. It is concluded that older adults participate in regular long-term of Wai Tan Kung exercise have a positive effect on their cardiovascular fitness. Therefore, such kind of exercise may especially fit for older adults.
Key words: oxygen uptake (VO2), ventilation (VE), heart rate, heart rate variability, Wai Tan Kung exercise.
Coupling between flexible ship and liquid sloshing using potential flow analysis
No full textThe significant increase in demand for Liquefied Natural Gas (LNG) and the economic aspects of its transportation resulted in increases in the number and size of LNG carriers. One of the design issues for LNG carriers is the sloshing phenomenon because containment systems widely used nowadays have no internal structures. Furthermore, because the weights of ship and cargo are comparable and ship operators want more flexible operations allowing partial fillings in tanks, the coupling effect between ship motions and sloshing requires further investigation, including the effect of ship distortion.The previous study on coupling between rigid body and sloshing shows good agreement between methods of prediction and measurements[1,2]. Hence, in this paper the potential flow approach adopted for the coupling effect between rigid body ship motion and sloshing is extended to flexible ship-partially filled tank system, using the de-singularised Rankine source method. In this case, the global deflection of the flexible ship is used for application of the body boundary condition on the partially filled tank. The aim of this paper is to investigate the influence of hull flexibility on the hydrodynamic forces and moments associated with liquid sloshing and vice versa, as well as the dynamic characteristics (e.g. resonance frequencies) of the whole system. As there are no experimental results available, the method is validated by comparing hydrodynamic forces from sloshing obtained using rigid and flexible body approaches. The coupling effect between flexible ship and sloshing in partially filled tanks is investigated for an idealized LNG Carrier in beam regular waves, considering different partial filling scenarios

Dispatch of lay responders to out-of-hospital cardiac arrests
No full textBackground and aim: Out-of-hospital cardiac arrest (OHCA) remains a major public-health problem affecting around 300 000 Europeans each year. If treatment is not started within a couple of minutes the chances of survival are slim. One important predictor of survival is the time from call to start of treatment. To reduce this time frame, different strategies, in addition to emergency medical services (EMS), such as widespread deployment of automated external defibrillators (AEDs) and dispatch of fire fighters and police officers have been implemented. The aim of this thesis is to study the implementation and effects of a third additional resource, lay responders dispatched by the emergency dispatch center. The aim of study 1 was to evaluate the technical function and performance of a lay responder system during a run-in phase. The aim of study 2 was to measure the travelling speed and response time of the dispatched lay responders. In study 3 the aim was to investigate the emotional response, both positive and negative, wellbeing and post-traumatic stress disorder, among dispatched lay responders. In study 4 the aim was to investigate if lay responders instructed to fetch a public AED by using a smartphone application could increase the bystander use of AEDs before arrival of EMS, fire fighters and police officers.Methods and results: In study 1 data from the smartphone application were collected and linked to cardiac arrest data from the Swedish Register for Cardiopulmonary Resuscitation (SRCR). During six months in 2016 the system was activated 685 times. 224 of these cases were EMS treated OHCAs. After exclusion of EMS-witnessed cases (n=11) and cases with missing survey data (n=15), 198 cases remained in the analytical sample. The results showed that dispatched lay responders reached the scene in 116 cases (58%), in 51 (26%) cases before the EMS. An AED was attached 17 times (9%) and defibrillated 4 times (2%). The median Euclidian distance to travel to perform CPR was 560 meters (IQR=332-860) compared with 1280 (IQR=748-1776) among for those who were directed to fetch an AED. In study 2, data on lay responder movement were collected from the smartphone application. During the 7-month study period 1406 suspected OHCAs were included. In these calls, 9058 lay responders accepted the mission and 2176 reached the scene of the suspected cardiac arrest (the study population). Among all cases the median travelling speed was 2.3 meters/sec (IQR=1.4–4.0) while the response time was 6.2 minutes, and the travelling distance was 956 meters (IQR=480–1661). In the most densely populated areas the median travelling speed was 1.8 meters/sec compared with 3.1 in the least densely populated areas. In study 3 we included 886 unexposed and 1389 exposed lay-responders. The lay responders were divided into 3 groups; unexposed, exposed-1 (who tried, but failed to reach the scene before EMS) and exposed-2 (who either reached the scene before EMS or performed CPR). Using the two dimensions of the Swedish Core Affect Scales (SCAS), valence and activation the results suggested that exposed lay responders showed higher activation (Exp-1=7.5, Exp-2=7.6) than unexposed lay responders (7.0) (pConclusions: The conclusion from the first run-in study (study 1) was that it is feasible to dispatch lay responders to suspected OHCAs but that further system improvements are needed to reduce the time to defibrillation. The results from study 2 suggested that lay responders travel faster than previously estimated and that the travelling speed is dependent on population density, information that may be used for simulation studies as well as in configurations in app-based systems. Study 3 showed that lay responders rated the experience as high-energy and mostly positive. No indication of harm was seen, as the lay responders had low post-traumatic stress scores and high levels of general wellbeing at follow-up. Study 4 revealed that smartphone dispatch of lay responders to public AEDs did not increase the AED attachment rate before arrival of the EMS or first responders, versus smartphone dispatch to perform CPR. If dispatched lay responders arrived prior to the EMS, the likelihood of bystander AED use and CPR was increased.List of scientific papersI.
