Worlding aspirations and resilient futures: Framings of risk and contemporary city‐making in Metro Cebu,the Philippines

In the Philippines, calls for creating ‘global’, ‘sustainable’ and ‘resilient’ cities are placing urban poor communities in increasingly precarious positions. These communities have long been the targets of urban development and ‘modernisation’ efforts; more recently the erasure of informal settlements from Philippine cities is being bolstered at the behest of climate change adaptation and disaster risk management (DRM) agendas. In Metro Cebu, flood management has been at the heart of DRM and broader urban development discussions, and is serving as justification for the demolition and displacement of informal settler communities in areas classed as ‘danger zones’. Using Kusno's (2010) interpretation of the ‘exemplary centre’ as a point of departure, this paper interrogates the relationship between DRM, worlding aspirations (Roy and Ong, 2011) and market‐oriented urbanisation in Cebu, and considers the socio‐spatial implications of these intersecting processes for urban poor communities. Through analysing the contradictions inherent in framings of certain bodies and spaces as being ‘of risk’ or ‘at risk’ over others, I argue that the epistemologies of modernity, disaster risk and resilience endorsed and propagated by the state are facilitating processes of displacement and dispossession that serve elite commercial interests under the auspices of disaster resilience and pro‐poor development.     

Resettling,disconnecting or displacing? Attending to local sociality,culture and history in disaster settings

In many disaster settings, top‐down responses emphasise ‘expert‐led’ solutions that often involve relocating disaster‐affected communities. While the intention might be to move people from harm's way and facilitate recovery, failure to attend to local pre‐disaster circumstances as well as the interplay between power, resilience and vulnerability within and around affected communities often sees resettlement reconfigure as displacement or disconnection. This oversight may even usher in a new phase of dispossession and disadvantage for marginalised groups (particularly in colonial settings). This paper explores experiences in Australia, Japan and Taiwan to reflect on what issues of local sociality, local culture and local resilience need to be attended to in framing ‘better’ disaster responses.     

盆栽康乃馨切花生长发育综合调控

本研究为调控盆栽康乃馨切花的生长发育,提高观赏品质,采用温度、光照、植物生长调节剂和摘心等方法对盆栽康乃馨切花生长发育进行综合调控。结果表明:摘心起到很好的矮化作用,伸长量明显降低,同时分枝数增多、花期推后,开花期与对照相比,一次摘心的推后25 d,二次摘心的推后40 d;在光照培养箱中培养的盆栽康乃馨生长健壮,并延长花期7 d;100 mg/L的矮壮素处理的康乃馨植株伸长量明显降低,植株矮化,长势健壮;5 mg/L、10 mg/L、30 mg/L的B9以及30 mg/L、50mg/L矮壮素处理的植株叶长不同程度的缩短;5 mg/L的B9以及30 mg/L、70 mg/L、100mg/L的矮壮素处理的植株叶宽不同程度的增加,70 mg/L的矮壮素对叶宽的影响比对照(p<0.05)具有显著的差异;不同浓度的B9和矮壮素处理对开花期有不同程度的推后作用,花期延长,不同浓度B9处理的比对照花期平均延长4.5 d,不同浓度矮壮素处理的平均延长6.5 d。上述研究结果为盆栽康乃馨切花的生产和品质提升提供理论参考。     

脐橙新品种‘龙回红’果实发育后期外观品质及内在营养成分的动态变化

‘龙回红’脐橙由‘纽荷尔’脐橙芽变而来,2012年经江西省农作物品种审定委员会认定的脐橙新品种,其变异株系适应性强,多数生物学性状均优于其母本‘纽荷尔’脐橙。为更全面了解该脐橙品种在果实发育成熟阶段的外观品质及内在营养成分的动态变化情况,本研究以‘龙回红’脐橙及其母本‘纽荷尔’脐橙为试材,对以上两个脐橙品种果实发育后期的相关生理生化指标进行测定,结果表明:随着果实的发育成熟,‘龙回红’和‘纽荷尔’的外观品质(单果重及横,纵径,果皮色差指数)呈逐渐上升的变化趋势;可溶性固形物(total soluble solid, TSS)、总糖、维生素C (vitamin C, Vc)含量呈先上升后下降的趋势,可滴定酸(titratable acid,TA)含量呈逐渐下降的变化趋势。‘龙回红’脐橙果实的红绿色差a*、色差指数(citrus colour index, CCI)、TSS、总糖含量、单果重及横、纵径均高于‘纽荷尔’脐橙,TA和Vc含量低于‘纽荷尔’,其外观品质和果实风味优于‘纽荷尔’脐橙。     

Urban Public Space Development in Harbin Driven by Music Culture Intervention

"Social event driving" has become a way to promote urban development, create urban public spaces and create a city image. As one of the important big cities in northeastern China, Harbin enjoys the reputation of "The Music City", and its public space development is inextricably linked with the driving of music culture. This paper started with the analysis of the correlation between the development of urban public spaces and the development of music culture in Harbin, and studied the influence and driving role of music culture on the construction and development of urban public spaces.     

遮光处理对文心兰生长发育和生理指标的影响

以文心兰切花品种‘金辉’为试材,研究了在遮光率分别为60%、70%、80%、90%条件下其生长发育和生理指标的变化情况,分析了切花文心兰生长发育和生理指标与光照条件的关系,以期为筛选适宜光照条件提供参考。结果表明:持续60%遮光率显著降低花序梗长,且在夏季强光照时叶绿素含量显著降低,相对电导率显著上升;持续90%遮光率显著降低茎叶中可溶性糖、还原糖含量,同时假鳞茎长、假鳞茎茎围、开花率、花序长、分叉数及花朵数也显著降低;持续70%遮光率不仅开花率、花序长、分叉数及花朵数最高,且在夏季强光照时可溶性糖、还原糖的累积量最高,利于文心兰切花栽培。
