Product Differentiation, Multi-product Firms and Estimating the Impact of Trade Liberalization on Productivity
In this paper I analyze the productivity gains from trade liberalization in the Belgian textile industry. So far, empirical research has established a strong relationship between opening up to trade and productivity, relying almost entirely on deflated sales to proxy for output in the production function. The latter implies that the resulting productivity estimates still capture price and demand shocks which are most likely to be correlated with the change in the operating environment, which invalidate the evaluation of the welfare implications. In order to get at the true productivity gains I propose a simple methodology to estimate a production function controlling for unobserved prices by introducing an explicit demand system. I combine a unique data set containing matched plant-level and product-level information with detailed product-level quota protection information to recover estimates for productivity as well as parameters of the demand side (markups). I find that when correcting for unobserved prices and demand shocks, the estimated productivity gains from relaxing protection are only half (from 8 to only 4 percent) of those obtained with standard techniques.
The Impact of Implementing a Culturally Responsive Latino Poetry Unit to Examine Language, Identity, and Culture in a Middle School Language Arts Classroom
The purpose of this practitioner research study was to examine the implementation of a culturally responsive poetry unit in a majority Latino middle school in Nebraska. The experiences of Latino and non-Latino eighth-grade language arts students were documented in an effort to understand the level of engagement and conclusions drawn from the poetry. This study also explores the effectiveness of using a multicultural poetry unit to address state standards. Data sources include student written work, whole-class and individual discussions, pre and post surveys, and daily entries in a teacher research journal. Latino students found the poetry to be representative of their experiences as bicultural and bilingual citizens. Non-Latino students acquired an increased cross-cultural understanding. Additionally, while there did appear to be an increased understanding of poetry and the standards among students, it did not translate to an increased appreciation of poetry.

Benefits of the Snakemake Workflow Management Software in Comparison to Traditional Programming (Paper)
Tools surrounding bioinformatics have increased data acquisition and accuracy significantly, especially with near-real time results using nanopore DNA sequencing. With large amounts of data, reproducibility is of high importance, and long workflows can become convoluted. Snakemake, built on the Common Workflow Language and Python, aims to alleviate this with readable formatting, reproducibility, and portability for any machine. Using 97 fastq files, the usability of these three traits were compared between a Bash and Snakemake workflow using a range of one to twelve threads. In every test, Snakemake was faster than Bash. At its fastest, Snakemake was 27% faster than Bash. Reproducibility of both workflows was verified using an MD5 hash of results. The hashes differed between the workflows; this may be a result of executing the workflows in two different terminal environments. Despite this, it is a valid method of validating reproducibility between tests within individual workflows. Outside speed tests, Snakemake offers quality of life features that allow it to pull ahead from Bash. Containerization of workflows using Conda is one example of this. The ability to require specific versions of software within a workflow boosts reproducibility. Additionally, portability is increased because the container can be deployed almost anywhere, and the required software can be downloaded on an as-needed basis. With readability comes maintainability. Snakemake will almost always pull ahead of Bash in this regard with its simple input, output, and shell fields. The field of Bioinformatics is moving very quickly, and it can be difficult for traditional Bash scripts to keep up in certain aspects. While Bash is paramount in the execution of some software, more powerful tools like Snakemake are required to handle the execution of an entire, complex workflow.https://openprairie.sdstate.edu/honors_isp/1007/thumbnail.jp
Creative Destruction and Productivity Growth in an Emerging Economy Evidence from Slovenian Manufacturing
In most transition countries the aggregate level evidence suggests that most
industries are just destroying jobs, due to the legacy of communism where overmanning
levels of employment were the norm. This paper sheds light on whether the
transition process in Slovenian manufacturing has been one of just destruction or in
contrast one of creative destruction. To this end we start by documenting gross job
flows for the Slovenian manufacturing sector between 1994 and 2000. In contrast to
slowly reforming transition economies where the transition process in manufacturing
is characterized by little job creation and high job destruction, we find for Slovenian
manufacturing a process of both substantial job creation and destruction. This
indicates that restructuring in Slovenia involves a substantial reallocation process. We
find higher job reallocation in private and small firms where the contribution of entry
and exit to the job reallocation process is higher.
We further use the Olley-Pakes methodology to estimate total factor productivity
(TFP) and show that TFP has increased in most sectors. We find that this is mainly
driven by existing firms becoming more efficient and by the net entry process, i.e.
more efficient firms enter the industry
