Four additional “intermediate” males were collected at another site, Natural National Park Los Nevados, El Jordán at 3100 meters, in Risaralda, and three males with the opposite condition (<i>A. socapa</i> aedeagus but without head markings) were collected at two additional sites in Risaralda (reported under <i>A. socapa</i>). The “La Pastora” site specimens also include several typical males of <i>A. socapa</i>. This suggests the possibility of hybridization at sites in Risaralda, or, perhaps the head pattern character is less reliable than previously thought.</p>Published as part of <i>Zúñiga, Maria del Carmen, Stark, Bill P., Cardona, William, Tamaris-Turizo, César & Ortega, Oscar E., 2007, Additions To The Colombian Anacroneuria Fauna (Plecoptera: Perlidae) With Descriptions Of Seven New Species, pp. 127-149 in Illiesia 3 (13)</i> on page 140, DOI: <a href="http://zenodo.org/record/4754665">10.5281/zenodo.4754665</a>
The Benefits of Being Economics Professor A (and not Z)
No full textAlphabetic name ordering on multi-authored academic papers, which is the convention in the economics discipline and various other disciplines, is to the advantage of people whose last name initials are placed early in the alphabet. As it turns out, Professor A, who has been a first author more often than Professor Z, will have published more articles and experienced afaster growth rate over the course of her career as a result of reputation and visibility. Moreover, authors know that name ordering matters and indeed take ordering seriously: Several characteristics of an author group composition determine the decision to deviate from the default alphabetic name order to a significant extent.performance measurement, incentives, economists, name ordering
The physical and practical problems experienced by cancer survivors: a rapid review and synthesis of the literature
No full textPurpose: a rapid and comprehensive review to identify what is known and not known about the physical and practical problems faced by adult cancer survivors.Methods: a systematic literature review process was used. This focused on published reviews to enable a fast but rigorous identification of both the gaps and well-researched areas within survivorship.Results: the search identified 5121 reviews, of which 42 were screened and 9 met the quality and inclusion criteria. The majority of papers focused on physical well being (n = 6) with the remaining papers focusing on practical well being (employment and finance). The quality of the reviews varied (ranging from weak to good). Gaps identified include sexual function, lower-limb lymphoedema, peripheral neuropathy, bladder and GI problems, hormonal sequelae, older cancer survivors, work impact of cancer and context-specific unmet supportive care needs. The review found a lack of standardised nomenclature for survivorship and methodological limitations.Conclusions: four main gaps in knowledge relating to the practical and physical problems associated with cancer survivorship have been identified. These are key symptoms, unmet supportive care needs, employment and older cancer survivors, and should be addressed by future research and systematic literature reviews. Work is also needed to address the nomenclature of survivorship and to improve the methodology of research into cancer survivors (including standardised measures, theoretical frameworks, longitudinal design, inclusion of older survivors and age-matched controls for comparison). The review highlighted the need for better research within the identified areas in order to improve the experiences of cancer survivor
Final word on Jersey Dutch
No full textIn this article, William Z. Shetter compares and contrasts the dialects that developed between different Dutch colonies in the New World. He explores in-depth the nuances of Jersey Dutch, and provides theories to explain how Dutch and colonial languages blended.

Dynamics of non-Hermitian Floquet Wannier–Stark system
No full textWe study the dynamics of the non-Hermitian Floquet Wannier–Stark system in the framework of the tight-binding approximation, where the hopping strength is a periodic function of time with Floquet frequency . It is shown that the energy level of the instantaneous Hamiltonian is still equally spaced and independent of time t and the Hermiticity of the hopping term. In the case of off resonance, the dynamics are still periodic, while the occupied energy levels spread out at the resonance, exhibiting t ^z behavior. Analytical analysis and numerical simulation show that the level-spreading dynamics for real and complex hopping strengths exhibit distinct behaviors and are well described by the dynamical exponents z = 1 and , respectively

A Pilot Survey for C III] Emission in the Reionization Era: Gravitationally Lensed Z ∼ 7–8 Galaxies in the Frontier Fields Cluster Abell 2744
No full textWe report results of a search for C iii] 1907, 1909 Å emission using Keck's MOSFIRE spectrograph in a sample of 7 candidates () lensed by the Hubble Frontier Field cluster Abell 2744. Earlier work has suggested the promise of using the C iii] doublet for redshift confirmation of galaxies in the reionization era given that Lyα (λ1216 Å) is likely attenuated by the neutral intergalactic medium. The primary challenge of this approach is the feasibility of locating C iii] emission without advanced knowledge of the spectroscopic redshift. With an integration time of 5 hr in the H band, we reach a median flux limit (in between the skylines) of ergs cm−2 s−1 but no convincing C iii] emission was found. We also incorporate preliminary measurements from two other CLASH/HFF clusters in which, similarly, no line was detected, but these were observed to lesser depth. Using the known distribution of OH emission and the photometric redshift likelihood distribution of each lensed candidate, we present statistical upper limits on the mean total C iii] rest-frame equivalent width (EW) for our sample. For a signal-to-noise ratio of 5, we estimate that the typical C iii] doublet rest-frame EW is, with 95% confidence, Å. Although consistent with the strength of earlier detections in brighter objects at , our study illustrates the necessity of studying more luminous or strongly lensed examples prior to the launch of the James Webb Space Telescope
