Over the past decade, there has been an increase in enrollment in computer science-related programs at colleges and universities. This surge can be attributed to the expansion of the technology industry during this period and the need for a technologically knowledgeable workforce, resulting in a diverse influx of students with varying levels of expertise and knowledge in computer science.

We are providing a mixed-method case study of student collaborations on a programming assignment in an introductory physics course for non-majors. Clustering techniques provide insights on code similarity, and network analysis uncovers social networking in the completion of the assignment. These results are complemented by an open-ended survey, which aims to explain the formation of these network structures, as well as elicit affective and epistemological feedback. It was found that students generally underestimate the size of their collaboration network, except for students who feel overwhelmed by the task-these students believe that everybody copies. The crucial question whether student learning is aided or hindered by these collaborations leads to recommendations for future implementations of programming activities and assignments in physics courses.

The nucleotide sequence of a 2248 bp (base pair) portion of the plasmid mini-F was determined. This region includes the replication origin and all plasmid-coded information required for replication. The same region is also capable of expressing incompatibility. A striking feature of the sequence is the presence of nine 19 bp repeating units. Four of these repeats, all arranged in one direction, comprise a cluster, and the remaining 5, all arranged in the opposite direction, comprise another cluster. These clusters are separated by a region of about 850 bp that encodes a hypothetical 29 kd [kilodalton] polypeptide. This region has sequences highly homologous to those found in the origin regions of the Escherichia coli and Salmonella typhimurium genomes.
