    Early History of Survey and Core Courses with Implications for Information Systems Education

    Recent proposals for a model MIS curriculum recommend that all business students be exposed to an introductory course. It is assumed that this course is a survey course, covering the spectrum of hardware, software, personnel, data, and information. In taking for granted that readers know the nature and purpose of a survey course, curriculum authors are tapping into ideas and experiences so common that no one feels the need to examine them. This article focuses on the history and philosophy of the survey course. Survey courses have played an integral role in the business curriculum since the advent of collegiate business schools. However, we shall show that the development of such a course and the way it plays in the MIS curriculum is an unsettled issue. We see that it is far from settled how to develop such a course and the role it plays in the broader curriculum. Two ideas concerning the survey course emerge and are in continual tension: the survey as the introduction to the field for future specialists and the survey as transmitter of fundamental ideas and skills to all business students. The broader implications for information systems education are discussed

    Networking Skills and Hiring Managers

    Providing career opportunities is the major goal of many a college and university. Institutions which offer these programsrequire an efficient and timely method for determining which skills to teach in their programs. In addition, the job searchprocess itself requires additional skills such as interviewing and networking. This research postulates that the skill set andmethods of looking for new employees differ for the hiring manager versus the non-hiring manager. Specifically, hiringmanagers may place more emphasis on networking as a way to find employees and may require a different set ofcommunication and technical skills. A research design is discussed

    Genetic, textual, and archeological evidence of the historical global spread of cowpea (Vigna unguiculata [L.] Walp.)

    [EN] Cowpea (Vigna unguiculata [L.] Walp.) was originally domesticated in sub-Saharan Africa but is now cultivated on every continent except Antarctica. Utilizing archeological, textual, and genetic resources, the spread of cultivated cowpea has been reconstructed. Cowpea was domesticated in Africa, likely in both West and East Africa, before 2500 BCE and by 400 BCE was long established in all the modern major production regions of the Old World, including sub-Saharan Africa, the Mediterranean Basin, India, and Southeast Asia. Further spread occurred as part of the Columbian Exchange, which brought African germplasm to the Caribbean, the southeastern United States, and South America and Mediterranean germplasm to Cuba, the southwestern United States, and Northwest MexicoSIThis study was supported by the Feed the Future Innovation Lab for Climate Resilient Cowpea (USAID Cooperative Agreement AID-OAA-A-13-00070), the National Science Foundation BREAD project “Advancing the Cowpea Genome for Food Security” (NSF IOS-1543963), and Hatch Project CA-R-BPS-5306-

    Identification of QTL controlling domestication-related traits in cowpea (Vigna unguiculata L. Walp)

    [EN] Cowpea (Vigna unguiculata L. Walp) is a warm-season legume with a genetically diverse gene-pool composed of wild and cultivated forms. Cowpea domestication involved considerable phenotypic changes from the wild progenitor, including reduction of pod shattering, increased organ size, and changes in flowering time. Little is known about the genetic basis underlying these changes. In this study, 215 recombinant inbred lines derived from a cross between a cultivated and a wild cowpea accession were used to evaluate nine domestication-related traits (pod shattering, peduncle length, flower color, days to flowering, 100-seed weight, pod length, leaf length, leaf width and seed number per pod). A high-density genetic map containing 17,739 single nucleotide polymorphisms was constructed and used to identify 16 quantitative trait loci (QTL) for these nine traits. Based on annotations of the cowpea reference genome, genes within these regions are reported. Four regions with clusters of QTL were identified, including one on chromosome 8 related to increased organ size. This study provides new knowledge of the genomic regions controlling domestication-related traits in cowpea as well as candidate genes underlying those QTL. This information can help to exploit wild relatives in cowpea breeding programsSIThis work was supported by grants from the Generation Challenge Program (TL1), the Feed the Future Innovation Lab for Climate Resilient Cowpea (Cooperative Agreement AID-OAA-A-13-00070), and the NSF BREAD project “Advancing the Cowpea Genome for Food Security’’ (Award #1543963)’’.

We also thank Abdou Souleymane (INRA, Niger) for helping to identify the wild parent, Stefano Lonardi and Steve Wanamaker (University of California Riverside, USA) for the cowpea genome sequence and annotations, and Dr. Paul Gepts (University of California Davis, USA) for his valuable input

    The UCR Minicore: a resource for cowpea research and breeding

    Special Issue on Legume Genomics[EN] Incorporation of new sources of genetic diversity into plant breeding programs is crucial for continuing to improve yield and quality, as well as tolerance to abiotic and biotic stresses. A minicore (the “University of California, Riverside (UCR) Minicore”) composed of 368 worldwide accessions of cultivated cowpea has been assembled, having been derived from the UCR cowpea collection. High-density genotyping with 51,128 SNPs followed by principal component and genetic assignment analyses identified six subpopulations in the UCR Minicore, mainly differentiated by cultivar group and geographic origin. All six subpopulations were present to some extent in West African material, suggesting that West Africa is a center of diversity for cultivated cowpea. Additionally, population structure analyses supported two routes of introduction of cowpea into the U.S.: (1) from Spain to the southwest U.S. through Northern Mexico and (2) from Africa to the southeast U.S. via the Caribbean. Genome-wide association studies (GWAS) narrowed several traits to regions containing strong candidate genes. For example, orthologs of the Arabidopsis FLOWERING LOCUS T lie within a major QTL for flowering time. In summary, this diverse, yet compact cowpea collection constitutes a suitable resource to identify loci controlling complex traits, consequently providing markers to assist with breeding to improve this crop of high relevance to global food and nutritional securitySIThis research was funded by the Feed the Future Innovation Lab for Climate Resilient Cowpea (USAID Cooperative Agreement AID-OAA-A-13-00070), the National Science Foundation BREAD project “Advancing the Cowpea Genome for Food Security” (NSF IOS-1543963), Hatch Project CA-R-BPS-5306-H.
