The Impact

Soil nutrients are the basis of ecological remediation. Soil amendments can form a reticular membrane structure on the soil surface to increase nutrient storage and alleviate nutrient imbalances, and are affected by the environmental temperature. At present, the qualitative evaluation of the effect of soil amendment is mainly based on vegetative growth. However, with the increasing use of soil amendments, how to conveniently and quantitatively evaluate the impact of soil amendments on ecological restoration under different temperature conditions from the perspective of soil urgently needs to be solved. Therefore, a new soil amendment named aqua-dispersing nano-binder (ADNB) and silty clay that is commonly used for ecological restoration in South China were used as research subjects, and the important soil nutrient storage capacity—soil conductivity index—was used as the starting point to find solutions to the above problems. We independently developed a multifunctional instrument to measure the soil amendment concentration. Clay conductivity measurements were used by adding different concentrations of ADNB within the range of 0 to 50 °C, and the mechanism by which temperature and ADNB affect the conductivity of clay was revealed. In addition, the quantitative relationship between the clay conductivity, ambient temperature and concentration of ADNB was elucidated. According to the growth conditions of melinis minutiflora and pigeon pea under different concentrations of ADNB, the optimal ADNB concentration needed to improve ecological restoration was obtained, which provided a new way to evaluate the effects of the large-scale use of soil modifiers on ecological restoration.

The Impact

In the light of postmodern debates in anthropology, ethnography offers anthropologists new ways of representing their objects of study. The politics involved in the production and consumption by feminist scholars and activists of women's representations in the Arab world, and Egypt specifically, provides the starting point of this article. Using an ethnographic text examining manifestations of ‘Islamic Feminism’ in Egypt, I explore problems in addressing the subject of veiling – a continuous favourite among researchers. Grappling with stereotypes, assumptions and pre-interpretations based on what we read before going to the field and the questions we formulate in our minds, I look towards strategies of engagement with research subjects where anthropologists can express their commitments to them. Research ethics and reflexivity offer no formulaic guarantees of better representations, but pave the way towards understanding one's motivations and urges ethnographers to examine the impact of their work, both on the immediate community, and with regard to larger power politics. Given the fluid nature of identities and the relative fixedness of representations, solutions do not appear in abundance. Working outside of unnecessary dichotomies and searching for incongruities presents interesting possibilities for future ethnographic research.

The Impact

Purpose – The purpose of this paper is to examine a range of issues and methods in relation to measuring the impact of volunteer labour on the design and delivery of all types of library services. With the increasing use of volunteers to deliver library and information services in all sectors, managers need to assess their effectiveness and evaluate the impact of their use in relation to operational service design and delivery, and on the development of the profession and professional practice as a whole. Presented here is an initial scoping study, outlining a range of issues, methods and challenges for more detailed future investigation. Design/methodology/approach – A number of methodological challenges and perspectives are identifiable. Contemporary libraries exhibit increasing similarities with Third Sector organisations, namely a complex stakeholder community, and increasing use of volunteers to supplement or replace services delivered by professional staff. Therefore, a starting point for the research is a systematic review and analysis of the methodologies developed by the Third Sector Research Centre, and those studies in the ESRC contemporary Developing Impact Evaluation strand. As a rich picture is required, both quantitative and qualitative approaches are necessary, with the overall study adopting a mixed methods approach. Findings – This paper reports the findings of the preliminary documentary analysis, literature review and scoping aspects of a large-scale study. Originality/value – Research undertaken to date (June 2014) has failed to identify any published systematic review and examination of these issues.

The Impact

The Arab Spring took policymakers and academics by surprise. The starting point, the scope, nor the impact had been seen coming. This was primarily because of academics’ irrevocable belief in the stabilising power of authoritarian regimes. In light of this failing, the article will critically discuss the production of crisis knowledge on the basis of four major early warning tools. These are World Bank’s greed/grievance model, the predictive model by the Political Instability Task Force, the risk and capacity approach applied by the Failed States Index, and the International Crisis Group. The article will add to the debate in two ways. First, the analysis will show that prevention research can be biased in ways that crucially influence policymakers’ assessment of states at risk. Second, the article will argue in favour of a complementary perspective that includes the analysis of conflicts that do not erupt into large-scale violence against all odds (so-called ‘negative cases’).

PurposeThis paper aims to examine the impact of an open-plan office (OPO) space organisation on a user’s attitude in the Algerian context; more specifically, it investigates gender differences in the occupants’ perception of such working environment. It, principally, aims to explore the employees’ reaction towards OPO and sees how much such local office type complies with indoor environment quality (IEQ) and psychological comfort.Design/methodology/approachThe theoretical framework of the study is mainly related to environmental psychology referring to the interaction between users and their environment. Post-occupancy evaluation was carried out using exploratory study and questionnaires, followed by statistical analyses. It was performed on a large-scale sample of employees (296 employees) working in recently built OPO situated in Oran (Algeria).FindingsFundamentally, women appear to show more concern regarding comfort. They do not show much reluctance to be mixed with men in a large office space as opposed to more conservative reaction towards mixing up in outdoor public space environment. As for environmental factors (IEQ), indicators have shown the inadequacy of most buildings in terms of thermal, light or noise comfort. The study has also revealed that a majority of users recognise the professional advantages of the OPO, although it is suggested that their preferred type would be the individual office.Originality/valueThe paper provides a concise starting point for future research interested in developing Algerian context OPO design in terms of both indoor environmental and psychological comfort.

The Impact

<p>The ClimXtreme program funded by the German Ministry of Education and Research is designed to address Physics and Processes, Statistics, and Impacts of meteorological extreme events, considering both the past period covered by instrumental measurements, and future climate scenarios. In its branch on impacts, the impact of hazards in Europe (convective events, severe precipitation, heat waves and droughts, and large scale storms) shall be considered in order to identify the underlying relevant weather situations and the antecedent meteorological factors. The specific characteristics of the extreme events shall also be explored. Aiming at a better understanding of the impacts of the extremes, investigations shall go beyond quantification of the local severity of a hazard. The assumption is that there is also an influence of weather and climate on exposure and vulnerability. These factors for the occurrence and the magnitude of damaging impacts  thus depend on local climatology, the occurrence of specific weather sequences augmenting vulnerability, or the occurrence of specific combinations of factors which individually needn’t be extreme (compound events).  One starting point are thus already existing impact models, which do not take (all of) these factors into account. Results from numerical climate models will be used to estimate the future change of risks under climate change.</p>

AbstractHave the various profound changes that have affected the world, and particularly its geostrategic dimensions, since the end of the Cold War radically altered the nature of conflicts? Twenty years after the collapse of the Soviet Union and ten years after the destruction of the twin towers in New York, there is an apparent degree of continuity in the resilience of former centres of unresolved conflicts and of armed groups involved in them. Nonetheless, whereas most armed conflicts can today be classified as ‘intra-state’, the general context has changed to the extent that reference is now made to the phenomenon of ‘new wars’. Increasingly inacceptable economic and political imbalances along with globalization, environmental damage and its consequences or the emergence of large-scale conflicts triggered by organized crime are some of the perils already affecting the nature of today's conflicts or potentially defining those of the future. As the period dominated by jihadist groups with a universalist vocation possibly draws to an end, the current trend seems to be towards a new generation of guerrilla fighters who stand to benefit, in particular, from the erosion of the nation-state and from geopolitical convulsions arising from the post-colonial legacy as the starting point for intensely zealous and violent long-term ventures. The impact of globalization could cause a flare-up of some existing conflicts that are currently limited in scope while the international community struggles to redefine other rules and to adapt them to the new dialectic of war and peace.

Abstract Little is known about whether people make good choices when facing important decisions. This article reports on a large-scale randomized field experiment in which research subjects having difficulty making a decision flipped a coin to help determine their choice. For important decisions (e.g. quitting a job or ending a relationship), individuals who are told by the coin toss to make a change are more likely to make a change, more satisfied with their decisions, and happier six months later than those whose coin toss instructed maintaining the status quo. This finding suggests that people may be excessively cautious when facing life-changing choices.
