title: Weed Ecology and Weed Management Strategies for Dry-Seeded Rice in Asia

description: Rice is a principal source of food for more than half of the world population, and more than 90% of rice worldwide is grown and consumed in Asia. A change in establishment method from manual transplanting of rice seedlings to dry-seeded rice (DSR) has occurred in some countries as growers respond to increased costs or decreased availability of labor or water. However, weeds are a major constraint to DSR production because of the absence of the size differential between the crop and the weeds and the suppressive effect of standing water on weed growth at crop establishment. Herbicides are used to control weeds in DSR, but because of concerns about the evolution of herbicide resistance and a scarcity of new and effective herbicides, there is a need to integrate other weed management strategies with herbicide use. In addition, because of the variability in the growth habit of weeds, any single method of weed control cannot provide effective and season-long control in DSR. Various weed management approaches need to be integrated to achieve effective, sustainable, and long-term weed control in DSR. These approaches may include tillage systems; the use of crop residue; the use of weed-competitive cultivars with high-yield potential; appropriate water depth and duration; appropriate agronomic practices, such as row spacing and seeding rates; manual or mechanical weeding; and appropriate herbicide timing, rotation, and combination. This article aims to provide a logical perspective of what can be done to improve weed management strategies in DSR.

title: When to Protect? Using the Crosswise Model to Integrate Protected and Direct Responses in Surveys of Sensitive Behavior

description: Sensitive survey techniques (SSTs) are frequently used to study sensitive behaviors. However, existing strategies for employing SSTs lead to highly variable prevalence estimates and do not permit analysts to address the question of whether the use of an SST is actually necessary. The current paper presents a survey questioning strategy and corresponding statistical framework that fills this gap. By jointly analyzing survey responses generated by an SST (the crosswise model) along with direct responses about the sensitive behavior, the paper's framework addresses the question of whether the use of a SST is required to study a given sensitive behavior, provides an efficient estimate of the prevalence of the sensitive behavior, and, in its extended form, efficiently estimates how individual characteristics relate to the likelihood of engaging in the behavior. The utility of the approach is demonstrated through an examination of gender differences in proclivities towards corruption in Costa Rica.

title: Investigating deposits in Harvard Dataverse's Root dataverse

description: &lt;p&gt;To prevent people from publishing spam in Harvard Dataverse, repository staff are considering publishing workflows that prevent people from publishing datasets and/or dataverses into the repository's "Root" dataverse until repository staff can verify that account creators won't deposit spam.

&lt;p&gt;To help estimate the number of "Root"-depositor accounts and deposits that staff may have to vet each day, the Jupyter notebook included in this dataset analyzes two years of user account data, included in the tabular file, to try to answer:
&lt;ul&gt;
&lt;li&gt; How many datasets and dataverses, that have gone on to be published, have been created in Root each day?
&lt;li&gt; How many accounts have created more than one of these datasets in Root?
&lt;li&gt; How many accounts created these datasets in Root each day, and which of those accounts are first time depositors versus returning depositors?

title: Development and impact of site specific nutrient management in the Red River Delta of Vietnam

description: Site-specific nutrient management (SSNM) for a more effective use of fertilizers in rice production was developed and validated in the Red River Delta (RRD) of northern Vietnam through a partnership of the Soils and Fertilizers Research Institute (SFRI) and the International Rice Research Institute (IRRI) beginning in 1997. The subsequent dissemination of validated SSNM practices involved collaboration of SFRI and IRRI with the extension system and Plant Protection Division (PPD). We review the development of SSNM in the RRD and estimate the impact of SSNM adoption at the farm level through a survey in 2007 of adopters and nonadopters of SSNM in Ha Nam and Ha Tay provinces. SSNM improved farmers' rice yield by 0.2 t ha-1 in Ha Nam and by 0.34 t ha-1 in Ha Tay in the spring season. SSNM adopters appeared to have improved fertilizer management. SSNM increased net annual income by US$57 ha-1 in Ha Tay and by $78 ha-1 in Ha Nam. Simple projections for the wide application of SSNM throughout the RRD indicate potential annual gains of 228,000 tons of additional unmilled rice. Based on frontier production functions, adopters achieved a slightly higher index of technical efficiency in rice production. SSNM improved farmers' knowledge, attitudes, and skills in rice farming.

title: A Ticket to the Olympics: An Assessment of the "Olympic Effect" on Tourism

description: Previous studies on the topic of the 'Olympic Effect' and its impact on tourism reveal both positive and negative returns for host countries as well as unsuccessful bid host countries. The returns experienced, as explained by subject scholars, are greatly dependent on a variety of factors, many of which are uncontrollable. Therefore, it is an undeniable risk for a country to host a sporting mega-event; however, the potential successful outcome generally overshadows any concern. Building off of previous research conducted, this paper explores the effects host countries and unsuccessful bid host countries of sporting mega-events experience in regards to tourism after an event takes place. It not only examines the Olympics, but also observes the FIFA Men's World Cup, since it is considered the second largest sporting mega-event after the Olympics. In this analysis, hosts and unsuccessful bid hosts were observed under a variety of controls to fully understand factors that affect outcomes on tourism. The majority of results show a positive increase in tourism for hosts and unsuccessful bid hosts. However, it is apparent that many of these results are byproducts of a naturally occurring time trend that causes sectors such as tourism to increase over time.

description: The study was conducted in 29 selected local governments across the four states and FCT. A total of 649 pregnant women and mothers or caregivers of children under five who received or bought Permanet. Using the recipients' register as sampling frame, respondents were selected at random from the register at the public health facilities of those who had access to the LLIN. Using the Lot Quality Assurance sampling techniques, all selected respondents were interviewed at the various LGAs. A Lot Assurance sampling technique was adopted to measure the coverage and utilization of the nets distributed through the public health facilities within the selected Local government areas across the four states and FCT in Nigeria. A lot can be defined as a community of catchment areas for a programme. For this purpose each of the Local Government Areas of the four states and FCT was taken as a lot.
