SME perceptions of and responses to the recession

The UK has recently experienced the worst recession since the 1930s. Despite the severity of this recent recession, there are currently few studies of its effect on small and medium-sized enterprises (SMEs). However, small business growth and entrepreneurship are recognised as essential drivers for economic recovery (Matlay, 2012; Rae, 2010). Drawing on an online bi-monthly survey of SMEs in Lincolnshire and Rutland, this paper explores owner managers’ perceptions of the UK recession. We examine the views of businesses on various aspects of the recession, and how this has affected business performance, levels of confidence, and growth ambitions. The paper explores the role of business confidence in the economy as a determinant of business growth intentions, and draws a comparison between perceptions and behaviour

Balancing Affordability and Opportunity: An Evaluation of Affordable Homeownership Programs With Long-Term Affordability Controls

Examines seven shared equity programs that allow low-income families to purchase homes at below-market prices with resale restrictions and their outcomes in terms of preserving affordability, personal wealth creation, security of tenure, and mobility

On the Power of Adaptivity in Sparse Recovery

The goal of (stable) sparse recovery is to recover a $k$-sparse approximation $x*$ of a vector $x$ from linear measurements of $x$. Specifically, the goal is to recover $x*$ such that ||x-x*||_p <= C min_{k-sparse x'} ||x-x'||_q for some constant $C$ and norm parameters $p$ and $q$. It is known that, for $p=q=1$ or $p=q=2$, this task can be accomplished using $m=O(k \log (n/k))$ non-adaptive measurements [CRT06] and that this bound is tight [DIPW10,FPRU10,PW11]. In this paper we show that if one is allowed to perform measurements that are adaptive, then the number of measurements can be considerably reduced. Specifically, for $C=1+eps$ and $p=q=2$ we show - A scheme with $m=O((1/eps)k log log (n eps/k))$ measurements that uses $O(log* k \log \log (n eps/k))$ rounds. This is a significant improvement over the best possible non-adaptive bound. - A scheme with $m=O((1/eps) k log (k/eps) + k \log (n/k))$ measurements that uses /two/ rounds. This improves over the best possible non-adaptive bound. To the best of our knowledge, these are the first results of this type. As an independent application, we show how to solve the problem of finding a duplicate in a data stream of $n$ items drawn from ${1, 2, ..., n-1}$ using $O(log n)$ bits of space and $O(log log n)$ passes, improving over the best possible space complexity achievable using a single pass.Comment: 18 pages; appearing at FOCS 201

A fresh look at paralytics in the critically ill: real promise and real concern.

Neuromuscular blocking agents (NMBAs), or "paralytics," often are deployed in the sickest patients in the intensive care unit (ICU) when usual care fails. Despite the publication of guidelines on the use of NMBAs in the ICU in 2002, clinicians have needed more direction to determine which patients would benefit from NMBAs and which patients would be harmed. Recently, new evidence has shown that paralytics hold more promise when used in carefully selected lung injury patients for brief periods of time. When used in early acute respiratory distress syndrome (ARDS), NMBAs assist to establish a lung protective strategy, which leads to improved oxygenation, decreased pulmonary and systemic inflammation, and potentially improved mortality. It also is increasingly recognized that NMBAs can cause harm, particularly critical illness polyneuromyopathy (CIPM), when used for prolonged periods or in septic shock. In this review, we address several practical considerations for clinicians who use NMBAs in their practice. Ultimately, we conclude that NMBAs should be considered a lung protective adjuvant in early ARDS and that clinicians should consider using an alternative NMBA to the aminosteroids in septic shock with less severe lung injury pending further studies
