Stationary reflection principles and two cardinal tree properties

We study consequences of stationary and semi-stationary set reflection. We show that the semi stationary reflection principle implies the Singular Cardinal Hypothesis, the failure of weak square principle, etc. We also consider two cardinal tree properties introduced recently by Weiss and prove that they follow from stationary and semi stationary set reflection augmented with a weak form of Martin's Axiom. We also show that there are some differences between the two reflection principles which suggest that stationary set reflection is analogous to supercompactness whereas semi-stationary set reflection is analogous to strong compactness.Comment: 19 page

Eastern Europeans in Contemporary Literature and Culture:Imagining New Europe

This timely volume provides the first comprehensive study of the way in which contemporary writers, filmmakers and the media have represented the recent phenomenon of Eastern European migration to the UK and Western Europe following the enlargement of the EU in the 21st century, the social and political changes after the fall of communism, and the Brexit vote. Exploring the recurring figures of Eastern Europeans as a new reservoir of cheap labour, the author engages with a wide range of both mainstream and neglected authors, films and programmes, including Rose Tremain, John Lanchester, Marina Lewycka, Polly Courtney, Dubravka Ugresic, Kapka Kassabova, Kwame Kwei-Armah, It's a Free World, Gypo, Britain's Hardest Workers, The Poles are Coming and Czech Dream. Analyzing the treatment of Eastern Europeans as builders, fruit pickers, nannies and victims of sex trafficking, and ways of resisting the stereotypes, this is an important intervention into debates about Europe, migration, and post-communist transition to capitalism, as represented in multiple contemporary cultural texts

Recovery from Breast Cancer : Investigating the role of resilience in breast cancer survivorship

Breast cancer is a common event among women, one in ten women receiving a breast cancer diagnosis in their lifetime. The experience of breast cancer is a complex process that entails a multitude of interlinked potentially highly stressful events. It is thus evident that the manner in which one reacts to such stressors can have a substantial impact on both physical and mental health. Resilience is a construct that encompasses a positive adaptation to adverse events, and has been shown to be associated with both physical and mental health-related outcomes in breast cancer patients and survivors. Nevertheless, resilience is a complex construct which has been poorly operationalized in previous research. Additionally, there is a gap in research on how resilience changes over time, how these changes relate to the recovery process, as well as the lived experiences relevant for resilience in breast cancer survivors. The present thesis aims to address these gaps in knowledge. The general aim of this thesis was to better understand the role of resilience in recovery from breast cancer. The main aim of Study I was to elucidate the factor structure of the Connor-Davidson Resilience Scale (CD-RISC), the most widely used instrument for assessing resilience, as well as to determine its discriminant and predictive validity in the Swedish non-clinical setting. The aim of Study II was to explore whether resilience changes from the time of receiving a breast cancer diagnosis to after treatment, as well as whether these changes in resilience mediate or moderate physical and mental health-related recovery from breast cancer. It also aimed to identify biopsychosocial risk factors for poor or slower recovery. Study III aimed to explore the lived experiences and aspects of resilience among breast cancer survivors.Study I suggested that a 22-item unidimensional model of CD-RISC should be retained. It suggested that factors related to religion and spirituality may not play a role in resilience in this setting. Study I found that CD-RISC had good discriminant validity, being a separate construct from emotion regulation. Moreover, it had good predictive validity, as it predicted physical and mental health-related quality of life after adjusting for health and sociodemographic factors. Study II found that resilience was associated with both mental and physical health-related quality of life in breast cancer patients across time. However, resilience did not change substantially over time, and the process of recovery could thus not be explained by the changes in resilience. More resilient patients over time also did not have a faster recovery. Nevertheless, resilience was found to be protective, especially for mental health at diagnosis. Study II also identified a variety of clinical and sociodemographic factors which may be risk factors for poorer recovery, most notably ER negative and HER2 positive tumors, more advanced cancer at diagnosis, receiving adjuvant chemotherapy, and lower socioeconomic status. Study III identified three important aspects relevant for resilience in breast cancer survivors. Having agency in relation to one’s health, treatment procedures, feelings, thoughts, and daily functioning was one important aspect of resilience. Important others play a complex direct and indirect role in resilience in the context of breast cancer. Conceptualizing breast cancer as a closed chapter as opposed to a constant was an important aspect of resilience throughout survivorship.Overall, the studies included in this thesis suggest that resilience plays an important role in breast cancer survivorship, with implications for not only mental, but also physical health. Interventions aimed at enhancing resilience in breast cancer survivors may focus on increasing agency and social support, as well as changing beliefs about the finality of breast cancer

OCA and automorphisms of P(ω) ⧸ fin

AbstractLet OCA denote the Open Coloring Axiom. We show that OCA+MAℵ1 implies that P(ω)⧸fin and P(ω1)/fin have only trivial automorphisms. Under PFA for any infinite cardinal κ all automorphisms of P(κ)⧸fin are trivial

On Indestructible Strongly Guessing Models

In \cite{MV} we defined and proved the consistency of the principle ${\rm GM}^+(\omega_3,\omega_1)$ which implies that many consequences of strong forcing axioms hold simultaneously at $\omega_2$ and $\omega_3$. In this paper we formulate a strengthening of ${\rm GM}^+(\omega_3,\omega_1)$ that we call ${\rm SGM}^+(\omega_3,\omega_1)$. We also prove, modulo the consistency of two supercompact cardinals, that ${\rm SGM}^+(\omega_3,\omega_1)$ is consistent with ZFC. In addition to all the consequences of ${\rm GM}^+(\omega_3,\omega_1)$, the principle ${\rm SGM}^+(\omega_3,\omega_1)$, together with some mild cardinal arithmetic assumptions that hold in our model, implies that any forcing that adds a new subset of $\omega_2$ either adds a real or collapses some cardinal. This gives a partial answer to a question of Abraham \cite{AvrahamPhD} and extends a previous result of Todor\v{c}evi\'{c} \cite{Todorcevic82} in this direction

Acute Stroke Multimodal Imaging: Present and Potential Applications toward Advancing Care.

In the past few decades, the field of acute ischemic stroke (AIS) has experienced significant advances in clinical practice. A core driver of this success has been the utilization of acute stroke imaging with an increasing focus on advanced methods including multimodal imaging. Such imaging techniques not only provide a richer understanding of AIS in vivo, but also, in doing so, provide better informed clinical assessments in management and treatment toward achieving best outcomes. As a result, advanced stroke imaging methods are now a mainstay of routine AIS practice that reflect best practice delivery of care. Furthermore, these imaging methods hold great potential to continue to advance the understanding of AIS and its care in the future. Copyright © 2017 by Thieme Medical Publishers, Inc
