Linear actions of Z/p×Z/p\mathbb{Z}/p\times\mathbb{Z}/p on S2n−1×S2n−1S^{2n-1}\times S^{2n-1}

We consider free actions of $(\mathbb{Z}/p)^2$ on $S^{2n-1}\times S^{2n-1}$ given by linear actions of $(\mathbb{Z}/p)^2$ on $\mathbb{R}^{4n}$. Simple examples include a lens space cross a lens space, but $k$-invariant calculations show that other quotients exist. Using the tools of Postnikov towers and surgery theory, the quotients are classified up to homotopy by the $k$-invariants and up to homeomorphism by the Pontrjagin classes. We will present these results and demonstrate how to calculate the $k$-invariants and the Pontrjagin classes from the rotation numbers.Comment: 12 page

Bridging the Gap: Bridge Designer to Project Manager

As engineers advance through their careers, their experience in survey, hydraulics, scour analysis, environmental considerations, permits, maintenance of traffic, and other design elements make them excellent candidates to transition into PM roles. In this session, two bridge engineers who now manage complex road and bridge projects and help mentor staff to similar opportunities will share their experiences and provide advice to those seeking management positions

Z/p×Z/p\mathbb Z_{/p}\times \mathbb Z_{/p} actions on Sn×SnS^n\times S^n

We determine the homotopy type of quotients of $S^n \times S^n$ by free actions of $\mathbb Z_{/p} \times \mathbb Z_{/p}$ where $2p>n+3$. Much like free $\mathbb Z_{/p}$ actions, they can be classified via the first $p$-localized $k$-invariant, but there are restrictions on the possibilities, and these restrictions are sufficient to determine every possibility in the $n=3$ case. We use this to complete the classification of free $\mathbb Z_{/p} \times \mathbb Z_{/p}$ actions on $S^3 \times S^3$, for $p>3$, by reducing the problem to the simultaneous classification of pairs of binary quadratic forms. Although the restrictions are not sufficient to determine which $k$-invariants are realizable in general, they can sometimes be used to rule out free actions by groups that contain $\mathbb Z_{/p}\times\mathbb Z_{/p}$ as a normal Abelian subgroup.Comment: 20 page

The emotional response to athletic injury: Re-injury anxiety

First paragraph: Injury is often an unfortunate consequence of participation in sport. With increased participation, and subsequent increased injury rates, athletic injury is now a significant health concern (Brewer, 1998). Some studies have clearly demonstrated that athletic injury has, not only a physical, but also, an emotional impact upon the injured athlete (e.g., Daly, Brewer, Van Raalte, Petitpas, & Sklar, 1995; Gould, Udry, Bridges, & Beck, 1997; Smith, Scott, O’Fallon, & Young, 1990)

Cardiac rehabilitation and psychological well-being

The aim of this chapter is to address psychological issues associated with effective multidimensional cardiac rehabilitation programmes. Cardiac rehabilitation is defined as: “the sum of activities required to influence favourably the underlying cause of the disease, as well as the best possible, physical, mental and social conditions, so that they (people) may, by their own efforts preserve or resume when lost, as normal a place as possible in the community. Rehabilitation cannot be regarded as an isolated form or stage of therapy but must be integrated within secondary prevention services of which it forms only one facet” (World Health Organisation, 1993). The chapter will: discuss the impact of CHD in the UK, provide an overview of the Government strategy for reducing the burden of cardiac disease and disability, and review quantitative evidence discussing the effectiveness of cardiac rehabilitation on the mental health and well-being of cardiac patients, with particular reference to anxiety and depression states. The final part of this chapter presents results of a qualitative study, previously reported in Hudson, Board, and, Lavallee (2001) that examined the psychosocial impact of cardiac disease and rehabilitation for patients attending one cardiac rehabilitation scheme in England

“Smart” Discourses, the Limits of Representation, and New Regimes of Spatial Data

As “smart” urbanism becomes more influential, spaces and places are increasingly represented through numeric and categorical data that has been gathered by sensors, devices and people. Such systems purportedly provide access to always visible, measurable and knowable spaces, facilitating ever-more rational management and planning. Smart city spaces are thus governed through the algorithmic administration and categorisation of difference, and structured through particular discourses of smartness, both of which shape the production of space and place on a local and general level. Valorization of data and its analysis naturalizes constructions of space, place, and individual that elide the political and surveillant forms of techno-cractic governance on which they are built. This article argues that it is through processes of measurement, calculation, and classification that “smart” emerges along distinct axes of power/knowledge. Using examples drawn from the British Home Office’s repurposing of charity outreach maps for homeless population deportation and the more recent EU EXIT document checking application for European citizens and family members living in the UK, we demonstrate the significance of Gunnar Olsson’s thought for understanding the ideological and material power of smartness via his work on the very limits of representation. The discussion further opens a bridge towards a more relational consideration of the construction of space, place, and individual through the thinking of Doreen Massey

Maintenance and Consolidation Therapy in Patients with Unresectable Stage III/IV Non-Small Cell Lung Cancer

Lung cancer remains the most common cancer and the leading cause of cancer-related mortality. Despite continuing improvements in chemoradiotherapy regimens and the recent clinical validation of particular agents as maintenance treatments in advanced disease, there remains an unmet need for new therapies with clinically proven value in the treatment of unresectable stage III NSCLC. Studies are under way to determine whether the use of anticancer vaccines may be an effective strategy in the treatment of NSCLC

Human rights and community work. Complementary theories and practices

Much effort has been placed on developing international understandings of human rights without the corresponding attention to responsibilities. The authors argue that a community development framework may be useful in re-conceiving human rights in a more holistic way, and that social workers and community development workers are well placed to be 'grass roots human rights workers
