Mechanical adaptations of cleavers (Galium aparine)

• Background and Aims Cleavers (Galium aparine) is a fast-growing herbaceous annual with a semi-self-supporting, scrambling-ascending growth habit. Mature plants often use upright species for support. It is common in hedgerows and on waste ground. This study aims to characterize the mechanical behaviour of the stem and roots of cleavers and relate this to the arrangement of structural tissue, the net microfibrillar orientations in the cell walls, and plant growth habit. • Methods The morphology and mechanics of mature cleavers was investigated using plants grown in pots and ones collected from the grounds at the University of Lincoln, Lincoln, UK. Tensile tests were carried out on the stem and the basal section of the first-order lateral roots. The net orientation of cellulose microfibrils in the cell walls was investigated using polarized light microscopy. • Key Results Results show that the basal regions of the stem and first-order lateral roots were highly extensible. Breaking strains of 24 ± 7 % were recorded for the stem base and 28 ± 6 % for the roots. Anatomical observations showed that the lower stem (base + 100 mm) was circular in cross-section with a solid central core of vascular tissue, whereas further up the stem the transverse section showed a typical four-angled shape with a ring-like arrangement of vascular tissue and sclerenchyma bundles in the corners. The net orientation of wall microfibrils in the secondary xylem diverges from the longitudinal by between 8 and 9°. • Conclusions The basal region of the stem of cleavers is highly extensible, but the mechanism by which the stem is able to withstand such high breaking strains is unclear; reorientation of the cellulose fibrils in the stem along the axis of loading is not thought to be responsible. Key words: Anatomy, adaptation, cleavers, Galium aparine, growth habit, mechanics, cellulose microfibril orientation, extensibilit

Sharing in the nation’s prosperity? Pensioner poverty in Britain

This commentary reviews the government’s tax and benefit reforms affecting pensioners to date, and examines the evidence from the latest official low income figures on the government’s record on pensioner poverty so far

Discounting Women: Doubting Domestic Violence Survivors’ Credibility and Dismissing Their Experiences

In recent months, we’ve seen an unprecedented wave of testimonials about the serious harms women all too frequently endure. The #MeToo moment, the #WhyIStayed campaign, and the Larry Nassar sentencing hearings have raised public awareness not only about workplace harassment, domestic violence, and sexual abuse, but also about how routinely women survivors face a Gaslight-style gauntlet of doubt, disbelief, and outright dismissal of their stories. This pattern is particularly disturbing in the justice system, where women face a legal twilight zone: laws meant to protect them and deter further abuse often fail to achieve their purpose, because women telling stories of abuse by their male partners are simply not believed. To fully grasp the nature of this new moment in gendered power relations—and to cement the significant gains won by these public campaigns—we need to take a full, considered look at when, how, and why the justice system and other key social institutions discount women’s credibility. We use the lens of intimate partner violence to examine the ways in which women’s credibility is discounted in a range of legal and social service system settings. First, judges and others improperly discount as implausible women’s stories of abuse, based on a failure to understand both the symptoms arising from neurological and psychological trauma, and the practical constraints on survivors’ lives. Second, gatekeepers unjustly discount women’s personal trustworthiness, based on both inaccurate interpretations of survivors’ courtroom demeanor and negative cultural stereotypes about women and their motivations for seeking assistance. Moreover, even when a woman manages to overcome all the initial modes of institutional skepticism that minimize her account of abuse, she often finds that the systems designed to furnish her with help and protection dismiss the importance of her experiences. Instead, all too often, the arbiters of justice and social welfare adopt and enforce legal and social policies and practices with little regard for how they perpetuate patterns of abuse. Two distinct harms arise from this pervasive pattern of credibility discounting and experiential dismissal. First, the discrediting of survivors constitutes its own psychic injury—an institutional betrayal that echoes the psychological abuse women suffer at the hands of individual perpetrators. Second, the pronounced, nearly instinctive penchant for devaluing women’s testimony is so deeply embedded within survivors’ experience that it becomes a potent, independent obstacle to their efforts to obtain safety and justice. The reflexive discounting of women’s stories of domestic violence finds analogs among the kindred diminutions and dismissals that harm so many other women who resist the abusive exercise of male power, from survivors of workplace harassment to victims of sexual assault on and off campus. For these women, too, credibility discounts both deepen the harm they experience and create yet another impediment to healing and justice. Concrete, systematic reforms are needed to eradicate these unjust, gender-based credibility discounts and experiential dismissals, and to enable women subjected to male abuses of power at long last to trust the responsiveness of the justice system

A Review of Recent Evaluation Efforts Associated with Programs and Policies Designed to Promote the Employment of Adults with Disabilities

The purpose of this report is to provide a review of the recent evaluation activities being conducted for a number of state and federal programs, policies, and initiatives designed to promote the employment of people with disabilities. The review is intended to provide a single source for information on the nature of the initiatives and the evaluation efforts that have been recently completed or are currently under way and the findings to date related to the effectiveness of these initiatives. This broad review is also intended to provide some evidence of the progress we are making. The report also suggests avenues where further efforts and progress might be warranted. We identified 27 initiatives or programs and their associated evaluations that represent a federally sponsored program, policy, or initiative designed specifically to improve employment of the working-age adult population with disabilities. Because of resource constraints, we did not review initiatives designed to improve the adult employment outcomes of youth with disabilities, such as the Social Security Administration (SSA) sponsored Youth Transition Demonstrations. We also did not review small-scale studies evaluating the effectiveness of specific clinical, supported employment, or vocational rehabilitation (VR) approaches. We only looked at information related to the major federal programs serving people with disabilities, general legislation and policies, and initiatives that were fairly large-scale in nature

Inequality and living standards in Great Britain: some facts

This Briefing Note is designed to provide some basic facts concerning living standards and inequality in Great Britain. Wherever possible, up-to-date sources have been given for further reading. Accompanying this Briefing Note is a spreadsheet of useful statistics relating to the income distribution in Britain. This can be downloaded from the IFS web site at http://www.ifs.org.uk/bns/bn19figs.zip. Both were last updated on 9 March 2004. Section I of this Briefing Note starts by setting out some of the issues and conceptual difficulties surrounding the measuring of living standards and inequality. A picture of the income distribution in Great Britain and many of the important trends in living standards is then presented in the sections that follow. In Sections II and III, we choose weekly before-housing-costs household equivalent income1 as our measure of living standards, as well as presenting some results on an after-housing-costs basis. Section IV then considers using weekly equivalent household expenditure (including housing costs) as a comparative measure of living standards. Section V cites research tracking the income of individuals across a number of years, while Section VI looks at work that attempts to assess how income status changes across generations. Sections VII, VIII and IX proceed by examining some of the factors responsible for the changes in inequality described, looking at the labour market, demographic changes and the impact of taxes and benefits. Section X concludes

Living standards, inequality and poverty

In this Election Briefing Note, we assess what has happened to living standards under Labour, setting out how average incomes, income inequality and poverty have changed since 1996- 97. We compare these changes with what happened under previous governments, and highlight where there have been differences between Labour's first and second terms

The government's child poverty target: how much progress has been made?

Before the 2001 election the Treasury said that `tax and benefit reforms announced in this Parliament will lift over 1.2 million children out of relative poverty'. But official figures released on 11 April show a smaller fall in child poverty, of only 0.5 million since 1996-97. This commentary attempts to explain the discrepancy. Using the data that lie behind the official Households Below Average Income publications, we analyse trend in child poverty, measured against various poverty lines, since 1979. We show how the government's choice of a relative poverty line is making its goal to abolish child poverty more difficult and more expensive. We also discuss how easy the government will find it to make further reductions in child poverty
