Hydrological Response of East China to the Variation of East Asian Summer Monsoon

Copyright © 2016 Fuxing Li et al.The sensitivity of hydrologic variables in East China, that is, runoff, precipitation, evapotranspiration, and soil moisture to the fluctuation of East Asian summer monsoon (EASM), is evaluated by the Mann-Kendall correlation analysis on a spatial resolution of 1/4° in the period of 1952-2012. The results indicate remarkable spatial disparities in the correlation between the hydrologic variables and EASM. The regions in East China susceptible to hydrological change due to EASM fluctuation are identified. When the standardized anomaly of intensity index of EASM (EASMI) is above 1.00, the runoff of Haihe basin has increased by 49% on average, especially in the suburb of Beijing and Hebei province where the runoff has increased up to 105%. In contrast, the runoff in the basins of Haihe and Yellow River has decreased by about 27% and 17%, respectively, when the standardized anomaly of EASMI is below -1.00, which has brought severe drought to the areas since mid-1970s. The study can be beneficial for national or watershed agencies developing adaptive water management strategies in the face of global climate change.

Temporal Regulation of LMP1 and Apoptosis Resistance After Primary EBV Infection

Epstein-Barr virus (EBV) is a ubiquitous human pathogen that establishes a lifelong latent infection in over ninety percent of all adult humans worldwide. While typically benign, EBV has been causally associated with a number of human malignancies in the settings of immune suppression, genetic, and/or environmental factors. While a highly successful pathogen based on prevalence, the ability of the virus to immortalize human B cells (a stage of infection thought to be critical for the establishment of latency) is quite poor. We hypothesize that the interactions between the virus and the human host early after infection are ultimately important for the outcome of viral latency establishment. To answer this question we broadly profiled primary human B cells at both early and late times after EBV infection to assay both host mRNA expression and the host-driven response to apoptotic stimuli. We found that EBV infection induces host gene expression signatures early after infection that are functionally distinct from the gene expression program late after infection. These studies also led to the novel discovery that viral gene expression is controlled differently early after infection, including the delayed expression of a viral protein that is critical for the establishment of latency. Furthermore, we have also shown that EBV can use a single viral protein to alter and repress host apoptotic sensitivity in the face of an anti-viral apoptotic response.

Margaret Thatcher, Dress and the Politics of Fashion

Through Margaret Thatcher’s private and public performances, the micro-politics of dress translated into the macro-politics of power. Thatcher’s changing career can be traced through her dress (see Young 1991: 416-417); analysis of her dress leading up to and during her Premiership reveals both her aspirations and increasing power. Understanding of Thatcher’s agency in her embodied, dressed performances can be informed and developed through Butler’s (1999) conceptualization of performativity. Through adaptation, repetition and divergent dress, Thatcher constructed different identities, some of which became iconic symbols of her self and her politics. Examination of Thatcher’s dress refines the understanding of the relationship between constraints and agency experienced by actors in the public realm. Upon becoming party leader, Margaret Thatcher’s gender, class and ideological viewpoints were incongruent with her unprecedented political status and she faced many challenges in attempting to overcome this. Dress became a potentially destabilising focus for her critics and symbolic of her “outsider” status. Yet in the face of these challenges she recognized and learned from the expectations of others, adapting and changing her dress. However, this was not an instantaneous, complete or permanent transformation. What Thatcher achieved, as she crafted her dressed performances, was agency over a further aspect of her life and her politics. There was also an evolving alignment of her dress with her political ideology and domestic and international roles over time.

Image usefulness of compressed surveillance footage with different scene contents

The police use both subjective (i.e. police staff) and automated (e.g. face recognition systems) methods for the completion of visual tasks (e.g person identification). Image quality for police tasks has been defined as the image usefulness, or image suitability of the visual material to satisfy a visual task. It is not necessarily affected by any artefact that may affect the visual image quality (i.e. decrease fidelity), as long as these artefacts do not affect the relevant useful information for the task. The capture of useful information will be affected by the unconstrained conditions commonly encountered by CCTV systems such as variations in illumination and high compression levels. The main aim of this thesis is to investigate aspects of image quality and video compression that may affect the completion of police visual tasks/applications with respect to CCTV imagery. This is accomplished by investigating 3 specific police areas/tasks utilising: 1) the human visual system (HVS) for a face recognition task, 2) automated face recognition systems, and 3) automated human detection systems. These systems (HVS and automated) were assessed with defined scene content properties, and video compression, i.e. H.264/MPEG-4 AVC. The performance of imaging systems/processes (e.g. subjective investigations, performance of compression algorithms) are affected by scene content properties. No other investigation has been identified that takes into consideration scene content properties to the same extend. Results have shown that the HVS is more sensitive to compression effects in comparison to the automated systems. In automated face recognition systems, `mixed lightness' scenes were the most affected and `low lightness' scenes were the least affected by compression. In contrast the HVS for the face recognition task, `low lightness' scenes were the most affected and `medium lightness' scenes the least affected. For the automated human detection systems, `close distance' and `run approach' are some of the most commonly affected scenes. Findings have the potential to broaden the methods used for testing imaging systems for security applications.

‘Learning to be Zen’: Women travellers and the imperative to happy

This paper follows the emotional management of lone, independent women travellers as they move through tourist spaces, based on my doctoral research Embodiment and Emotion in the experiences of independent women tourists (2012). Specifically, this paper will focus on ‘gendering happiness’ by arguing that women travellers are significantly compelled to feel and display characteristics of happiness, humour and ‘learning to be Zen’ in order to be successful travellers. The imperative to become, and remain, happy and humorous in the face of embodied, emotional and gendered constraints is a key feature of women’s reflections of their travelling experiences, mirroring the recent emergence of literature into happiness and positive thinking within feminist theory (Ehrenreich 2010, Ahmed 2010). Negotiating ‘bad’ emotions provides a powerful insight into the perceptions of women travellers; to remain happy can mask problematic power relations and other forms of resistance. This is not to say that emotional negotiation is not partly a form of effective resistance, rather, I wish to make room for the freedom to be unhappy and angry in travelling space without feeling failure for not achieving a successful travelling identity.

Female employment from the household. Towards a comprehensive analysis of work-life articulation

Research on women’s employment has proliferated over recent decades, often under a perspective that conceptualizes female labour market activity as independent of male presences and absences in the productive and reproductive spheres. In the face of these approaches, the article argues the need to focus on the couple as the unit of analysis of work-life articulation. After referring to the main theoretical arguments that, from a gender perspective within labour studies, have pointed out the relevance of placing the household as the central space for the analysis of the sexual division of labour, the article reviews different empirical contributions that have incorporated such perspective in the international literature. Next, the state of the art in the Spanish literature is presented, before arguing the desirability of applying such framework of analysis to the study of employment and care work in Spanish households, which are at present undergoing major transformations.

Estrategias resilientes ante la situación adversa de los desahucios

Los desahucios en España se han convertido en los últimos años en un fenómeno social emergente, de interés tanto para la investigación como para la intervención de los profesionales de la acción social. Aun así, no existen estudios suficientes relacionados con esta situación adversa, y menos aún centrados en las respuestas resilientes que las personas son capaces de ofrecer ante ella. Con el objetivo de identificar los factores internos y externos que se presentan en la experiencia de las familias que viven procesos de desahucios y que les están permitiendo desarrollar estrategias resilientes ante dicha adversidad, se lleva a cabo la presente investigación en la que participan 20 sujetos, pertenecientes a familias que acuden a la Plataforma de Afectados por las Hipotecas (PAH) de Málaga. A los participantes se les realiza una entrevista semi-estructurada y a través de ellas se han podido definir las características socio-familiares de las personas afectadas, las diferentes estrategias de afrontamiento desarrolladas, las principales fuentes de apoyo con las que han contado, así como las preocupaciones que les han acompañado. Los resultados muestran los principales factores internos y externos que están presenten en las estrategias resilientes que han desarrollado las familias afectadas por los desahucios durante el proceso vivido y destacan como fuente de apoyo informacional a la PAH. Se concluye con la necesidad de continuar con esta línea de investigación para tratar de diseñar intervenciones que refuercen y fomenten las estrategias de afrontamiento ante la situación adversa del desahucio.
