Targeted Poverty Alleviation and Households’ Livelihood Strategy in a Relation-Based Society: Evidence from Northeast China
2021
Although China is experiencing a transition from a relation-based society to a rule-based society, relationships among acquaintances still play an important role in resource allocation, such as the allocation of policy resources. This is particularly true in rural China, where targeted poverty alleviation is prevalent and a relation-based social structure still dominates. However, it is still unknown how relationships affect the livelihood strategy of households in rural China and how poverty alleviation policies plays a role between them. Therefore, this paper embeds poverty alleviation into the relation-based society and explores how households respond to the policy in this specific conte…
Connecting the data landscape of long-term ecological studies: the SPI-Birds data hub
2021
The integration and synthesis of the data in different areas of science is drastically slowed and hindered by a lack of standards and networking programmes. Long-term studies of individually marked animals are not an exception. These studies are especially important as instrumental for understanding evolutionary and eco-logical processes in the wild. Furthermore, their number and global distribution provides a unique opportunity to assess the generality of patterns and to address broad-scale global issues (e.g. climate change).
Updated Field Synopsis and Systematic Meta-Analyses of Genetic Association Studies in Cutaneous Melanoma: The MelGene Database
2015
We updated a field synopsis of genetic associations of cutaneous melanoma (CM) by systematically retrieving and combining data from all studies in the field published as of August 31, 2013. Data were available from 197 studies, which included 83,343 CM cases and 187,809 controls and reported on 1,126 polymorphisms in 289 different genes. Random-effects meta-analyses of 81 eligible polymorphisms evaluated in4 data sets confirmed 20 single-nucleotide polymorphisms across 10 loci (TYR, AFG3L1P, CDK10, MYH7B, SLC45A2, MTAP, ATM, CLPTM1L, FTO, and CASP8) that have previously been published with genome-wide significant evidence for association (P5 × 10(-8)) with CM risk, with certain variants pos…
Finanšu pārvaldes rīks izmantojot SSAS un Power BI
2019
Finanšu pārvaldes rīks pamatā spētu atvieglot ikdienas darbu finanšu nozarē strādājošajiem un dotu iespēju pieņemt lēmumus detalizētāk. Galvenā rīka funkcija ir atspoguļot finanšu datus daudz detalizētāk kā arī daudz plašāk. Finanšu pārvaldes rīks spēj apstrādāt datus no vairākām datu ieguves vietām, kā arī spēj tos attēlot nepieciešamajā veidā. Risinājums darbojas patstāvīgi 24/7, tas tiek nodrošināts izmantojot Azure mākoņpakalpojumus, kā SQL Database un SQL Server Analysis Service. Šie izanalizētie dati tiek vizuāli atspoguļoti iekš Microsoft Power BI datu vizualizācijas rīka. Ir iespēja izveidot unikālas vizualizācijas iekš Microsoft Power BI, kas tiek veidotas NodeJS vidē.
The HITRAN2016 molecular spectroscopic database
2017
This paper describes the contents of the 2016 edition of the HITRAN molecular spectroscopic compilation. The new edition replaces the previous HITRAN edition of 2012 and its updates during the intervening years. The HITRAN molecular absorption compilation is composed of five major components: the traditional line-by-line spectroscopic parameters required for high-resolution radiative-transfer codes, infrared absorption cross-sections for molecules not yet amenable to representation in a line-by-line form, collision-induced absorption data, aerosol indices of refraction, and general tables such as partition sums that apply globally to the data. The new HITRAN is greatly extended in terms of …
What to Expect and What to Focus on in SQL Query Teaching
2019
In the process of learning a new computer language, writing erroneous statements is part of the learning experience. However, some errors persist throughout the query writing process and are never corrected. Structured Query Language (SQL) consists of a number of different concepts such as expressions, joins, grouping and ordering, all of which by nature invite different possible errors in the query writing process. Furthermore, some of these errors are relatively easy for a student to fix when compared to others. Using a data set from three student cohorts with the total of 744 students, we set out to explore which types of errors are persistent, i.e., more likely to be left uncorrected by…
The Effects of Database Complexity on SQL Query Formulation (journal-first)
2020
The learning of practical Structured Query Language (SQL) skills often takes place in digital environments, where the learner writes queries against an exercise database. The exercise database is usually designed and implemented by the teacher, and populated with makeshift data. Although this approach is common, and SQL taught in almost all database courses, little scientific attention has been given to the nature of the exercise database.
RDB2OWL
2010
RDB2OWL is a simple approach of mapping relational databases into independently developed OWL ontologies. The approach is based on creating a mapping RDB schema, filling it with mapping information from which SQL scripts are generated that perform the instance-level transformation. We describe the RDB2OWL mapping schema and report on successful application of the technology to the migration of Latvian medical registries data.

An Information Aggregation and Analytics System for ATLAS Frontier
2019
International audience; ATLAS event processing requires access to centralized database systems where information about calibrations, detector status and data-taking conditions are stored. This processing is done on more than 150 computing sites on a world-wide computing grid which are able to access the database using the Squid-Frontier system. Some processing workflows have been found which overload the Frontier system due to the Conditions data model currently in use, specifically because some of the Conditions data requests have been found to have a low caching efficiency. The underlying cause is that non-identical requests as far as the caching are actually retrieving a much smaller num…
