The price of piracy in Somalia

Somalia is a country ravaged by political instability, internal strife and abject poverty – an ideal breeding ground for piracy. But the short term gains that have filtered through the economy from ransom payments have done little to address the country’s long term economic health, argues LSE’s Ryan Jablonski

The effect of controlled traffic on cotton yield and soil condition on three West Tennessee soils

The purpose of this investigation was to study the effects of a controlled traffic pattern on the physical condition of soil and the cotton yield. Three types of seedbed preparation were used; con-ventional, bedded, and none. Three types of equipment—two-row, fourrow, and six-row—were used; the traffic from this equipment was controlled such that the traffic remained on permanent wheel paths through the field. The controlled traffic pattern caused no severe adverse soil physical conditions. Also, yields from the bedded plots tended to exceed those from the conventional plots suggesting the possibility of reducing the number of pre-planting trips through the field

Captain Phillips and the causes of piracy

LSE’s Ryan Jablonski and Steven Oliver of the University of California, San Diego explore the reasons for piracy on the Somali economy

What politicians don’t know can hurt you: the effects of information on politicians’ spending decisions

Do well-informed politicians make more effective spending decisions? In experiments with 70% of all elected politicians in Malawi (N=460), we tested the effects of information on public spending. Specifically, we randomly provided information about school needs, foreign aid, and voting patterns prior to officials making real decisions about the allocation of spending. We show that these information interventions reduced inequalities in spending: treatment group politicians were more likely to spend in schools neglected by donors and in schools with greater need. Some information treatment effects were strongest in remote and less populated communities. These results suggest information gaps partially explain inequalities in spending allocation and imply social welfare benefits from improving politicians’ access to information about community needs

Software for Data Acquisition AMC Module with PCI Express Interface

Free Electron Laser in Hamburg (FLASH) and XRay Free Electron Laser (XFEL) are linear accelerators that require a complex and accurate Low Level Radio Frequency (LLRF) control system. Currently working systems are based on aged Versa Module Eurocard (VME) architecture. One of the alternatives for the VME bus is the Advanced Telecommunications and Computing Architecture (ATCA) standard. The ATCA based LLRF controller mainly consists of a few ATCA carrier boards and several Advanced Mezzanine Cards (AMC). AMC modules are available in variety of functions such as: ADC, DAC, data storage, data links and even CPU cards. This paper focuses on the software that allows user to collect and plot the data from commercially available TAMC900 board

One place doesn't fit all: improving the effectiveness of sustainability standards by accounting for place

Includes bibliographical references (pages 8-10).The growing interest in incentivizing sustainable agricultural practices is supported by a large network of voluntary production standards, which aim to offer farmers and ranchers increased value for their product in support of reduced environmental impact. To be effective with producers and consumers alike, these standards must be both credible and broadly recognizable, and thus are typically highly generalizable. However, the environmental impact of agriculture is strongly place-based and varies considerably due to complex biophysical, socio-cultural, and management-based factors, even within a given sector in a particular region. We suggest that this contradiction between the placeless generality of standards and the placed-ness of agriculture renders many sustainability standards ineffective. In this policy and practice review, we examine this contradiction through the lens of beef production, with a focus on an ongoing regional food purchasing effort in Denver, Colorado, USA. We review the idea of place in the context of agricultural sustainability, drawing on life cycle analysis and diverse literature to find that recognition of place-specific circumstances is essential to understanding environmental impact and improving outcomes. We then examine the case of the Good Food Purchasing Program (GFPP), a broad set of food-purchasing standards currently being implemented for institutional purchasing in Denver. The GFPP was created through a lengthy stakeholder-inclusive process for use in Los Angeles, California, USA, and has since been applied to many cities across the country. The difference between Los Angeles' process and that of applying the result of Los Angeles' process to Denver is instructive, and emblematic of the flaws of generalizable sustainability standards themselves. We then describe the essential elements of a place-based approach to agricultural sustainability standards, pointing toward a democratic, process-based, and outcome-oriented strategy that results in standards that enable rather than hinder the creativity of both producers and consumers. Though prescription is anathema to our approach, we close by offering a starting point for the development of standards for beef production in Colorado that respect the work of people in place

Structural network heterogeneities and network dynamics: a possible dynamical mechanism for hippocampal memory reactivation

The hippocampus has the capacity for reactivating recently acquired memories [1-3] and it is hypothesized that one of the functions of sleep reactivation is the facilitation of consolidation of novel memory traces [4-11]. The dynamic and network processes underlying such a reactivation remain, however, unknown. We show that such a reactivation characterized by local, self-sustained activity of a network region may be an inherent property of the recurrent excitatory-inhibitory network with a heterogeneous structure. The entry into the reactivation phase is mediated through a physiologically feasible regulation of global excitability and external input sources, while the reactivated component of the network is formed through induced network heterogeneities during learning. We show that structural changes needed for robust reactivation of a given network region are well within known physiological parameters [12,13].Comment: 16 pages, 5 figure
