    A Review of the Genus Serratella Edmunds, 1959 in China with Description of a New Species (Ephemeroptera: Ephemerellidae)
    (MDPI, 2022-11-04) Ding , Manqing; Jacobus, Luke M.; Zhou , Changfa; IUPUC Division of Science
    Species in the genus Serratella Edmunds, 1959 from China have never been compared and photographed systematically. Six valid Chinese Serratella species are recognized and revised in this paper. Among them, the imagos of S. brevicauda Jacobus et al., 2009 are unknown; the nymph of this species has a stout, strong body, with remarkably short caudal filaments and maxillary palpi. In contrast, only the imago stage of Serratella fusongensis (Su and You, 1988) (=Serratella longipennis Zhou et al., 1997, syn. nov.) is known; it has relatively long penes with small dorsal projections. The nymphs of S. setigera Bajkova, 1967 have small abdominal tergal spines but distinct, stout, blunt bristles on the spines, and the apexes of the male penes are round and shallowly divided. The fourth species, S. acutiformis sp. nov., which was collected from Western China, has sharp penial apexes (imagos) and large abdominal spines (nymphs). Unlike the former four species, S. ignita (Poda, 1761) and S. zapekinae Bajkova, 1967 has sub-quadrate penes without prominent dorsal projections. The nymph of S. ignita has lateral hair-like setae on the caudal filaments, while the nymph of S. zapekinae lacks such setae but has pairs of tubercles on the head and pronotum. Some characters used in the generic delineation of the genera Ephemerella Walsh, 1862 and Serratella, such as nymphal maxillary palpi and hair-like setae on caudal filaments as well as features of the imaginal penes and forelegs, are varied in Chinese species. However, all species in this paper have bifurcate ventral lamellae of gill VI. Our work highlights a need for further comparative systematic study of the genera Serratella, Ephemerella, and another related genus Torleya Lestage, 1917.

    IUPUI's HIP Taxonomy for ePortfolio: A Tool for Development, Implementation, and Scaling
    (National Institute for Learning Outcomes Assessment, 2021-11) Kahn, Susan; Freeman, Tyrone; Powell, Amy A.
    So-called High-Impact Practices (HIPs) are high-impact only when planned and executed thoughtfully, with attention to the relevant literature and the wisdom of experienced practitioners. After decades of experience with most HIPs, and national recognition for several, in 2016, IUPUI (Indiana University-Purdue University Indianapolis) undertook to create a series of HIP taxonomies describing the features needed to ensure that a given HIP experience will be truly high-impact. In 2018-2019, a committee of IUPUI HIPs and ePortfolio practitioners and experts convened to develop a similar taxonomy for ePortfolio, the most recently recognized HIP and one with which IUPUI already had nearly two decades of experience. In this Occasional Paper, we discuss the history of ePortfolio at IUPUI and what we came to understand about effective ePortfolio practice; the purposes of the taxonomies and of the ePortfolio taxonomy in particular; the development process for the taxonomy; our use of the ePortfolio taxonomy for professional development; and the attributes of high-impact ePortfolio practice that we identified, based on the growing literature on ePortfolio and on our campus and individual experiences. In the taxonomy and this paper, we emphasize the need for ePortfolio to be central to curricular design; embedded in pedagogies that support integrative learning and identity development; developed in concert with explicit instruction on “ePortfolio making”; and assessed holistically and in alignment with desired learning outcomes and experiences. The paper concludes with a case study from IUPUI’s Philanthropic Studies B.A. program, which discovered through its own ePortfolio work many of the same principles and practices reflected in the taxonomy and the literature.

    Towards Formalizing Adaptive Software Services
    (IEEE, 2016-08) Sharma, Sonali; Raje, Rajeev; Malhotra, Ruchika; Computer and Information Science, School of Science
    More and more complex, distributed and software-Intensive systems are built using independently developed services. Due to various reasons, such as changes in the execution environment, these systems may need to adapt their behavior. Although, adaptation at the system level has been extensively studied, developing adaptive services to start-with has not received any significant attention. This paper describes a framework for formalizing the concept of adaptation at the service level, leading to the "service adaptation by construction" approach. Hence, the proposed work will help software developers in identifying the important adaptation categories at the service level.
