Productivity in Higher Education/ Kevin Stange, Kevin Strange, Caroline M. Hoxby.
No full textIn English.How do the benefits of higher education compare with its costs, and how does this comparison vary across individuals and institutions? These questions are fundamental to quantifying the productivity of the education sector. The studies in Productivity in Higher Education use rich and novel administrative data, modern econometric methods, and careful institutional analysis to explore productivity issues. The authors examine the returns to undergraduate education, differences in costs by major, the productivity of for-profit schools, the productivity of various types of faculty and of outcomes, the effects of online education on the higher education market, and the ways in which the productivity of different institutions responds to market forces. The analyses recognize five key challenges to assessing productivity in higher education: the potential for multiple student outcomes in terms of skills, earnings, invention, and employment; the fact that colleges and universities are "multiproduct" firms that conduct varied activities across many domains; the fact that students select which school to attend based in part on their aptitude; the difficulty of attributing outcomes to individual institutions when students attend more than one; and the possibility that some of the benefits of higher education may arise from the system as a whole rather than from a single institution. The findings and the approaches illustrated can facilitate decision-making processes in higher education.Hoxby, Caroline M. / Stange, Kevin -- Staiger, Douglas -- Hoxby, Caroline M. -- Minaya, Veronica / Scott-Clayton, Judith -- Riehl, Evan / Saavedra, Juan E. / Urquiola, Miguel -- Altonji, Joseph G. / Zimmerman, Seth D. -- Courant, Paul N. / Turner, Sarah -- Vlieger, Pieter De / Jacob, Brian / Stange, Kevin -- Deming, David J. / Lovenheim, Michael / Patterson, Richard -- Carrell, Scott E. / Kurlaender, Michal -- Frontmatter -- Contents -- Acknowledgments -- Introduction / 1.

Gnopholeontini Stange 1994
No full textTribe Gnopholeontini Stange 1994 Diagnosis. Adult. Labial palpus short, palpimacula not extending to apex; hind femur without sensory hair; pretarsal claws not toothed nor strongly bent near base; tibial spurs present or absent; fore wing vein CuP originates distad of cross vein m-cu; fore wing vein 2A runs in a fairly even curve toward 3A; pilula axillaris present, usually well developed; hind wing vein CuA runs close to hind margin, ends near medial fork; hind wing radial sector originates before medial fork, 2 or 3 presectoral cross veins; male abdomen without hair pencils or postventral lobe; male paramere plate-like; female anterior gonapophysis plate-like or membranous; posterior gonapophysis inflated; pregenital plate with tooth; gonapophyseal plate large; female ectoproct with digging setae. Larva. Mandibular bases close together, separated by about basal width of mandible; mandible with 3 teeth, middle tooth closer to distal tooth than basal tooth; distal tooth not shorter than middle tooth; abdomen without dolichasters or tufted setae along median area, sometimes with lateral scoli. Biology. Larvae are either free living in sand (Tyttholeon Adams), live in protected areas (rock overhangs) (Menkeleon) or live on rocks or tree trunks (Gnopholeon Stange). The larvae of Maracandula are unknown, but evidence suggests they are associated with rocks. Some species (especially Maracandula) are afternoon fliers. Discussion. This tribe is characteristic of the Sonoran Region. The larvae of the different genera are among the most diverse found in the family and are quite distinct one from another. The main defining feature of this tribe is the larval structure, especially the close proximity of the mandibular bases. The adults differ from the Brachynemurini in lacking any well-developed postventral lobe on the male ectoproct and, probably more importantly, in the structure of the female terminalia which have the posterior gonapophysis inflated or enlarged and/or with an enlarged pregenital plate. Most of the genera (except Gnopholeon Stange) lack tibial spurs.Published as part of Miller, Robert B. & Stange, Lionel A., 2009, A revision of the genus Maracandula Currie (Neuroptera: Myrmeleontidae), pp. 1-10 in Insecta Mundi 2009 (101) on pages 1-2, DOI: 10.5281/zenodo.516786
