Gliricidia sepium Carbon Inputs and Soil Carbon Pools in a Costa Rican Alley Cropping System

Alternative land management practices, including agroforestry, help to maintain levels of soil organic matter (SOM) and can facilitate soil carbon (C) sequestration for mitigating atmospheric CO₂ emissions. This study quantified C inputs and determined the changes of the soil C pool in a 19-year-old Gliricidia sepium alley cropping system, studied at two fertiliser levels (tree prunings only [? N], and tree prunings plus chicken manure [+ N]), and was compared to a sole crop system. Carbon input from tree prunings ranged from 455 to 457 g C m^{? 2} y^{? 1}, whereas C inputs from crop residues were similar between alley- and sole crops ranging from 121 to 159 g C m^{? 2}y^{? 1}. The soil organic C (SOC) pool in the alley crop was 16–23% higher than the sole crop. In the 19th year of alley farming, SOC was significantly higher (p < 0.05) in the alley crop (3.2%) compared to the sole crop (2.4%), and was also greater compared to that at the time of establishment of the agroforestry system (2.8%). Gross SOC turnover to a 20-cm depth ranged from 12 to 14 years in the + N and ?N alley crops compared to 49 and 50 years in the + N and ?N treatments for the sole crops. Residue stabilisation efficiency in the alley crops was 39% and 55% in + N and ?N treatments respectively.     

The Earned Income Tax Credit: Targeting the poor but crowding out wealth

This paper quantifies the individual, aggregate and welfare effects of the US Earned Income Tax Credit (EITC). In particular, we analyze the labour supply and saving responses to changes in tax credit generosity and their implications for prices and welfare. Our results show that the EITC is a subsidy on labour income and a tax on savings. An increase in EITC generosity raises labour force participation, reduces savings for many and provides insurance to working poor households. The EITC reduces earnings inequality but increases the skill premium and wealth inequality. A 10% increase in tax credit generosity increases welfare by 0.31% and benefits the majority of the population.     

Innovation and HRM: Absences and politics

This article analyses the role of HRM practices in the implementation of an innovative cross-functional approach to new product development (concurrent engineering, CE) in Eurotech Industries. Contrary to CE methodology stipulations, and despite supportive conditions, HRM received scant attention in the implementation process. Organizational power and politics were clearly involved in this situation, and this article explores how their play created such HRM ‘absences’. The article builds on a four-dimensional view of power in order to provide a deeper understanding of the embedded, interdependent and political nature of HRM practice and innovation.

The influence of external reference price strategies in a nonprofit arts organization's “pay‐what‐you‐want” setting

Nonprofit arts organizations face conflicting objectives to balance—or more specifically, to create—artistic and educational value and to generate financial income from various sources. Pay‐what‐you‐want (PWYW), a participative pricing mechanism where services have no fixed price and customers actively decide what to pay, is a novel pricing mechanism and is of high interest for organizations and researchers alike. Based on the concepts of loss aversion and gain, this study presents a field experiment to test the effects of different PWYW pricing strategies on the amount of money paid by visitors of a German photo biennial. Explicitly, the provisions of minimum, maximum, and suggested external reference prices are compared to a setting with no external reference prices. We test the derived hypotheses, discuss the results, and provide implications for future research, as well as for the management of nonprofit arts organizations.     

Innovation and productivity in agricultural firms: evidence from a country-wide farm-level innovation survey

ABSTRACT

The literature on the links between innovation and productivity at the firm level in agriculture is almost nonexistent. In this paper, we analyze the factors behind the innovation effort of farms and the impact that innovation effort has on farm’s productivity, exploiting a unique farm-level agricultural innovation survey carried out in Uruguay. The results indicate that farm size, cooperation with other agents to perform R&D, the education of the owner of the farm, the participation of foreign capital and the existence of links with other organizations, in particular scientific, horizontal and vertical ones, are positively correlated with innovation effort. Public and private financial support are not clearly linked with innovation effort. The innovation effort has a positive effect on farm’s productivity. Some heterogeneities across industries in agriculture are found.     

IMPACT OF FINANCIAL INCLUSION IN LOW- AND MIDDLE-INCOME COUNTRIES: A SYSTEMATIC REVIEW OF REVIEWS

Financial inclusion programmes seek to increase access to financial services such as credit, savings, insurance and money transfers. Despite a wealth of systematic review evidence, the impacts of financial inclusion are inconclusive. Hence, the first systematic review of systematic reviews was undertaken to synthesize the impacts of financial inclusion interventions on economic, social, gender and behavioural outcomes. Thirty-two systematic reviews were identified. The headline finding is that impacts are more likely to be positive than negative, but the effects vary, and appear not to be transformative in scope or scale, as they largely occur in the early stages of the causal chain. The effects of financial services on core economic and social poverty indicators are small and inconsistent. There is no evidence for meaningful behaviour-change outcomes. The effects on women's empowerment appear generally positive, but they depend upon programme features that are often peripheral to the financial service, and cultural and geographical context. Accessing savings opportunities has small but more consistently positive effects for poor people, and bears fewer downside risks for clients than credit. The inconsistent quality of the primary evidence base that formed the basis of their syntheses raises concerns about the reliability of the overall findings.     

Wie Kundenintegration effizient gelingt

Zusammenfassung  Leistungen, die auf die speziellen Belange einzelner Nachfrager zugeschnitten sind, sind in den letzten Jahren zu einem immer bedeutenderen Wettbewerbsfaktor geworden. Die dazu n?tige Integration des Kunden in die Leistungserstellungsprozesse stellt die Anbieter jedoch vor erh?hte Anforderungen an ihr Prozessmanagement. Um dennoch die Effizienz der Leistungserstellung sicherzustellen und im Wettbewerb zu bestehen, sollten Anbieter neben den Prozessen im Unternehmen auch die kundenseitigen Prozesstrukturen berücksichtigen. Die Methode des Blueprinting und die Erfassung von Kognitiven Skripten sind hierfür geeignete Instrumente.

Local food production in a subarctic Indigenous community: the use of willow (Salix spp.) windbreaks to increase the yield of intercropped potatoes (Solanum tuberosum) and bush beans (Phaseolus vulgaris)

Addressing food security with local and sustainable food production is a key requirement for supporting a globally sustainable agricultural system. Food insecurity is prevalent in Indigenous communities in Canada, especially in rural and remote regions of northern (subarctic and arctic) Canada. Further, climate change has disproportionately impacted subarctic and arctic regions worldwide ? surface air temperatures are now more favourable for agricultural activities ? offering the potential for local food production under ambient conditions. The objectives of the present study were to evaluate bush bean (Phaseolus vulgaris L.) and potato (Solanum tuberosum L.) intercrops grown over a two-year period in two sites (treed, windbreak-lined with native willow, Salix. spp.; and non-treed, or open) in the subarctic Indigenous community of Fort Albany First Nation, Ontario, Canada. Intercrops grown in the windbreak-lined site produced significantly greater (p?3, NH₄ and total N) showed that with some local amendments such as offal and bone meal, both the windbreak-lined and open sites can support continued agricultural use. This study informs Indigenous communities across subarctic regions of the world that climate change not only brings challenges, but also opportunities, such as potentially sustainable local food production.
