ItemIs UNESCO World Heritage recognition a blessing or burden? Evidence from developing Asian countries(ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2017-10)To both acknowledge and protect many cultural heritage expressions, sites and practices, UNESCO has instituted three conventions; Tangible Heritage, Intangible Heritage and Diversity of Cultural Expression. If a site/practice receives this UNESCO badge, it is an acknowledgment of its universal cultural and/or natural value as well as recognition of the need to protect it from harm. However, the UNESCO badge is an important marketing tool in world tourism and its presence ensures many more visitors to a site/practice that is UNESCO recognised. With increasing wealth and mobility, many more people are travelling than was possible even a decade ago. Increasing numbers of visitors can negatively impact on a site/practice as well as affect the local culture and integrity of a region, particularly in developing countries. So, is the UNESCO recognition a blessing or burden? This paper addresses the challenges that ensue from the UNESCO conventions by considering three UNESCO World Heritage case study sites in Asian developing countries. In particular, it seeks to understand the extent to which UNESCO's World Heritage approach protects or further undermines the cultural heritage sustainability of these sites.

ItemOpen Access Arts Festivals and Artists: Who Benefits?(routle, 2019-09-03)Arts festivals are of interest to researchers, but the research focus is usually on the festival's economic or social impact. This approach does not usually reflect the engagement and experience of the artists involved. There has been controversy recently around the experiences of participating artists in open access arts festivals. Open access arts festivals are significant players in the festival landscape. They enable anyone to participate in a festival, if they pay a registration fee. This research, using a case study methodology, examines an open access festival from different perspectives with a focus on the experience of the participating artists.

METHODS: Thirteen databases were searched for RCTs from their inception through June 2013. Effects of qigong exercise were pooled across trials. Standardized mean differences (SMDs) were calculated for the pooled effects. Heterogeneity was assessed using the I2 test. The risk of bias was assessed using the Cochrane criteria. RESULTS: Seven RCTs met the inclusion criteria. Two RCTs suggested that qigong exercise immediately relieved anxiety among healthy adults, compared to lecture attendance and structured movements only. Four RCTs suggested qigong exercise relieved anxiety (pooled SMD = -0.75; 95% CI, -1.11 to -0.40), and three RCTs suggested that qigong exercise reduced stress (pooled SMD = -0.88; 95% CI, -1.22 to -0.55) among healthy subjects following one to three months of qigong practice, compared to wait-list controls. CONCLUSIONS: The available evidence suggests that qigong exercise reduces stress and anxiety in healthy adults. However, given the limited number of RCTs and their methodological flaws, further rigorously designed RCTs are needed.

ItemNo Preview AvailableBeyond Professional Competence(SAGE Publications, 2016-04)Health-care professionals who offer perinatal bereavement support often encountered numerous stressful events in daily practices. Secondary trauma and burnout related to psychological distress are not uncommon. Literatures suggested that further skill training enhances perceived self-competence thus lowering such traumatic impact. Nevertheless, equanimity, an emerging concept in professional development, which is characterized by a sense of unflappability and resilience in face of challenges, is an indispensable element in protecting the well-being of health-care professionals. The current study aimed to examine the role of equanimity and perceived self-competence on professional quality of life among health-care professionals. A city-wide survey study was conducted among 101 individuals who offered perinatal bereavement support at tertiary care institutions in Hong Kong. Perceived self-competence was positively associated with compassion satisfaction (β = .380, p < .001, CI = 0. 038, 0.131) and negatively correlated to burnout (β = −.439, p < .001, CI = −0.148, −0.055), in which both relationships were moderated by the level of equanimity, that is, the impact of perceived self-competence on professional quality of life was only significant among individuals with higher level of equanimity. It implied that perinatal bereavement training should integrate not only knowledge and skills but also component of equanimity training to facilitate the capacity building among frontline health-care professionals.

ItemNo Preview AvailableIntegrative body-mind-spirit intervention for concurrent sleep and mood disturbances: sleep-specific daytime functioning mediates sleep and mood improvements(WILEY, 2018-02)Sleep disturbances and depressive symptoms are associated closely with daytime dysfunctions, yet few studies have investigated their temporal relationship in a randomized controlled trial. We investigated the inter-relationships among sleep, depressive symptoms and daytime functioning following an integrative body-mind-spirit (I-BMS) intervention. One hundred and eighty-five participants (mean age 55.28 years, 75.1% female) with co-existing sleep and depressive symptoms were randomized to I-BMS or waiting-list. Daytime functioning variables included the daytime dysfunction items of the Pittsburg Sleep Quality Index (PSQI-day), Somatic Symptom Inventory, Hospital Anxiety Depression Scale and Short Form Health Survey collected at baseline, post-treatment and 3-month follow-up. Sleep and depressive symptoms were measured by the sleep items of the PSQI (PSQI-night) and Center for Epidemiological Studies Depression Scale (excluding the sleep item) (CESD-M). Regression and path analyses were used to understand the role of daytime functioning in sleep and depressive symptoms. We found significant group and time effects on almost all daytime variables and significant group × time interactions on PSQI-day and somatic symptoms. The adjusted regression model showed that CESD-M was associated with all daytime variables. However, PSQI-night was associated only with PSQI-day. Path analyses indicated that PSQI-day bridged PSQI-night and CESD-M in a two-way direction after the I-BMS intervention. The conclusion was that, following I-BMS intervention, improvement in daytime functioning was related predominantly to improvement in depressive symptoms. Night-time sleep related only to daytime dysfunction that was specific to sleep disturbances. Therefore, 'sleep-specific daytime impairment' could be regarded as a major link from night-time sleep to depressive symptoms. More studies are required to understand the concept of 'sleep-specific daytime impairment'.

ItemNo Preview AvailableProtocol for Psychosocial Interventions Based on Integrative Body-Mind-Spirit (IBMS) Model for Children with Eczema and Their Parent Caregivers(TAYLOR & FRANCIS INC, 2019-01-02)Purpose: Eczema is a pediatric skin disease that affects the psychosocial well-being of both children and their parent caregivers. This paper outlines a protocol for an experimental study that evaluates the effectiveness of a psychosocial empowerment program for children with eczema and their parent caregivers. Method: A multi-center randomized controlled trial is proposed, where parent-child dyads are randomized into two arms: an intervention group and wait-list control group. The intervention is delivered to participants in a parallel group format based on the Integrative Body-Mind-Spirit model which focuses on holistic well-being. Quality of life is measured before and after the intervention is provided, and five weeks after the intervention has been completed. Discussion: The suggested model fills a research gap in existing interventions, and provides new knowledge by evaluating the effectiveness of a tailored psychosocial intervention, delivered in group settings, for parent-child dyads affected by eczema.

ItemSynthesis and Characterisation of Helicate and Mesocate Forms of a Double-Stranded Diruthenium(ii) Complex of a Di(terpyridine) Ligand(CSIRO Publishing, 2019)A diruthenium(II) complex involving the di(terpyridine) ligand 1,2-bis{5-(5″-methyl-2,2′:6′,2″-terpyridinyl)}ethane was synthesised by heating an equimolar ratio of RuCl3 and the ligand under reflux conditions in ethylene glycol for 3 days, realising double-stranded helicate and mesocate forms which were chromatographically separated. The two species were obtained in relatively low yield (each ~7–9 %) from the reaction mixture. X-Ray structural studies revealed differences in the cavity sizes of the two structures, with the helicate structure having a significantly smaller cavity. Furthermore, the helicate and mesocate forms pack with notably different arrangements of the structures with the helicate having large solvent and anion filled pores. 1D/2D NMR studies revealed rigidity in the mesocate structure relative to that of the helicate, such that the –CH2CH2– signal was split in the former and appeared as a singlet in the latter. In a manner analogous to the behaviour of the parent [Ru(tpy)2]2+ coordination moiety (tpy = 2,2′:6′,2″-terpyridine), photophysical studies indicated that both the helicate and mesocate forms were non-emissive at ~610 nm at room temperature, but at 77 K in n-butyronitrile, both isomers showed emission at ~610 nm (λex 472 nm). However, the temporal emission characteristics were very different: time-resolved studies showed the emission of the helicate species decayed with a dominant emission lifetime of ~10 μs (similar to the emissive properties of free [Ru(tpy)2]2+ under the same conditions), whereas for the mesocate the emission lifetime was at least three orders of magnitude lower (~4 ns).

ItemLow-Bandgap Conjugated Polymer Dots for Near-Infrared Fluorescence Imaging(AMER CHEMICAL SOC, 2018-09)Low-bandgap conjugated polymers attract significant research interests because of their broad light absorption spectra in the red and near-infrared regions, making them desirable materials for solar photovoltaics. To date, low-bandgap conjugated polymers yield some of the best power conversion efficiencies offered by polymer solar cells. In addition to their applications as solar photovoltaic materials, nanoparticles of these polymers may be potentially beneficial for cell imaging because of their red and near-infrared absorption features, which are required for significant light penetration into biological samples. In this work, conjugated polymer dots (CPdots) of PCPDTBT, PSBTBT, PTB7, PCDTBT, and PBDTTPD are prepared in aqueous solution using nanoprecipitation. The maximum fluorescence wavelengths of these CPdots range from 800 to 1000 nm. The CPdots exhibit an average zeta potential of -30 mV, giving rise to colloidal stability of these nanoparticles. Dynamic light scattering results show that the CPdots have a hydrodynamic diameter of approximately 100 nm. Furthermore, analyses of atomic force microscopy images of the low-bandgap donor-acceptor CPdots show an average height of approximately 20 nm. The CPdots are introduced to live THP-1 cells, a human monocytic cell line, and the internalization of CPdots by these cells is observed. Confocal fluorescence microscopy images of cells labeled with the low-bandgap CPdots show the presence of these bright nanoparticles in the cells. In short, we demonstrate the preparation of low-bandgap CPdots as an aqueous dispersion and their applications in cell imaging.

ItemPhotophysical and Fluorescence Anisotropic Behavior of Polyfluorene β-Conformation Films(AMER CHEMICAL SOC, 2018-01-18)We demonstrate a systematic visualization of the unique photophysical and fluorescence anisotropic properties of polyfluorene coplanar conformation (β-conformation) using time-resolved scanning confocal fluorescence imaging (FLIM) and fluorescence anisotropy imaging microscopy (FAIM) measurements. We observe inhomogeneous morphologies and fluorescence decay profiles at various micrometer-sized regions within all types of polyfluorene β-conformational spin-coated films. Poly(9,9-dioctylfluorene-2,7-diyl) (PFO) and poly[4-(octyloxy)-9,9-diphenylfluoren-2,7-diyl]-co-[5-(octyloxy)-9,9-diphenylfluoren-2,7-diyl] (PODPF) β-domains both have shorter lifetime than those of the glassy conformation for the longer effective conjugated length and rigid chain structures. Besides, β-conformational regions have larger fluorescence anisotropy for the low molecular rotational motion and high chain orientation, while the low anisotropy in glassy conformational regions shows more rotational freedom of the chain and efficient energy migration from amorphous regions to β-conformation as a whole. Finally, ultrastable ASE threshold in the PODPF β-conformational films also confirms its potential application in organic lasers. In this regard, FLIM and FAIM measurements provide an effective platform to explore the fundamental photophysical process of conformational transitions in conjugated polymer.
