A Collective Impact Model Towards Increasing STEM Major Student Retention

The continued call to provide greater support for college and university student learning to encourage their completion of an increased number of degrees in science, technology, engineering, and math (STEM) is now coming from coordinated policy efforts that claim it is time to scale the adoption of evidence-based instructional practices and key strategies that may support students in their STEM courses (Committee on STEM Education of the National Science & Technology Council, 2018). While many important research efforts focus on isolated approaches by single or small groups of researchers, it may be time to consider the potential value of system-wide research approaches that encourages multi-disciplinary collaboration and conduct action research as a collective. At our university in 2014, a group of faculty with research interests in engineering education, chemistry education, physics education, mathematics education, and computer science education came together to design a series of interventions. These faculty were guided by university goals to support strategic STEM goals (Texas State University, 2013) and of assisting students to persist and succeed in their STEM courses and academic preparation for STEM careers. The intervention ideas proposed by this team included strategies to redesign courses; to provide mentoring and academic advising; to support supplemental instruction innovations; to establish learning communities; and to create academic and key skill development workshops for learners historically underrepresented in STEM and learners encountering new technologies. Educating a diverse, technologically capable workforce from all sectors of the population is of utmost importance (Page, 2007) and identifying best practices to support undergraduate students in particularly challenging fields such as in STEM was approached by this team as a collective effort. This paper presents the final report research findings of this research team s collective research effort at one university over a 5-year period as funded by the National Science Foundation sImproving Undergraduate STEM Education (IUSE) initiative. Specifically, this NSF initiative supports research proposals that include potentially effective approaches towards improving student learning in STEM while also offering high potential for broader societal impacts. The goal of this STEM education and research initiative was to create a professional learning community of faculty at a large university that would find ways to positively impact student learning, while attending to motivation and persistence of historically ABSTRACT
Molecular mechanisms of strain-stimulated intestinal epithelial cell differentiation and migration

MOLECULAR MECHANISMS OF STRAIN-STIMULATED INTESTINAL EPITHELIAL CELL DIFFERENTIATION AND MIGRATION by LISI YUAN May 2012 Advisor: Dr. Marc Basson Major: Anatomy and Cell Biology Degree: Doctor of Philosophy The intestinal epithelium is subjected to repetitive deformation during normal gut function by peristalsis and villous motility. In vitro, cyclic strain promotes intestinal epithelial proliferation and induces an absorptive phenotype characterized by increased dipeptidyl dipeptidase (DPPIV) expression. Schlafen 3 is a novel gene recently associated with cellular differentiation. We sought to evaluate whether Schlafen 3 mediates the effects of strain on the differentiation of IEC-6 intestinal epithelial cells in the absence or presence of cyclic strain. Strain increased Schlafen 3 mRNA and protein. In cells transfected with a control non-targeting siRNA, strain increased DPPIV specific activity. However, Schlafen 3 reduction by siRNA decreased basal DPPIV and prevented any stimulation of DPPIV activity by strain. Schlafen 3 reduction also prevented DPPIV induction by sodium butyrate (1mM) or TGF-β (0.1ng/ml), two unrelated differentiating stimuli. However, Shlafen-3 reduction by siRNA did not prevent the mitogenic effect of strain or that of EGF. Blocking Src and PI-3-kinase prevented strain induction of Schlafen 3, but Schlafen 3 induction required activation of p38 but not ERK.
Nannochloropsis oceanica Cultivation in Pilot-Scale Raceway Ponds—From Design to Cultivation

Raceways ponds are the microalgal production systems most commonly used at industrial scale. In this work, two different raceway configurations were tested under the same processing conditions to compare their performance on the production of Nannochloropsis oceanica. Biomass productivity, biochemical composition of the produced biomass, and power requirements to operate those reactors were evaluated. Water depths of 0.20 and 0.13 m, and culture circulation velocities of 0.30 and 0.15 m s−1 were tested. A standard configuration, which had a full channel width paddlewheel, proved to be the most energy efficient, consuming less than half of the energy required by a modified configuration (had a half channel width paddlewheel). The later showed to have slightly higher productivity, not enough to offset the large difference in energetic consumption. Higher flow velocity (0.30 m s−1) led to a 1.7 g m−2 d−1 improvement of biomass productivity of the system, but it increased the energy consumption twice as compared to the 0.15 m s−1 flow velocity. The latter velocity showed to be the most productive in lipids. A water depth of 0.20 m was the most suitable option tested to cultivate microalgae, since it allowed a 54% energy saving. Therefore, a standard raceway pond using a flow velocity of 0.3 m s−1 with a 0.20 m water depth was the most efficient system for microalgal cultivation. Conversely, a flow velocity of 0.15 m s−1 was the most suitable to produce lipids.
Standard of the Initial Ball Velocity for a Fly Ball in Baseball Hitting

This study aimed to determine the minimum required initial velocity to hit a fly ball toward the same field (left-field for right-handed batters), center field, and opposite field (right field for right-handed batters). Six baseball players hit fastballs launched by a pitching machine. The movements of the balls before and after bat-to-ball impact were recorded using two high-speed video cameras. The flight distance was determined using a measuring tape. Seventy-nine trials were analyzed, and the minimum required initial velocities of batted balls were quantified to hit balls 60, 70, 80, 90, 100, 110, and 120 m in each direction through regression analysis. As a result, to hit a ball 120 m, initial velocities of 43.0, 43.9, and 46.0 m/s were required for the same field, center field, and opposite field, respectively. The result provides a useful index for batters to hit a fly ball in each of the directions.
The Economic Case for Electric Vehicles in Public Sector Fleets: An Italian Case Study

The paper investigates whether it makes economic sense to use electric vehicles (EVs) in the public sector fleet. Thanks to the data collected in 2018 in 77 public sector entities in an Italian region, Friuli Venezia Giulia, we compare the total cost of ownership of a battery electric vehicle with that of a similar internal combustion engine one. We provide estimates for four scenarios (status quo, social cost internalization, price discounts and a combination of the last two) for three groups of public entities (local health authorities, municipalities and special purpose authorities) regarding passenger cars and mixed-use small light commercial vehicles. We find that, with the current price and cost structure, it makes economic sense to adopt EVs for a positive although relatively small percentage of the public sector fleet.
Impact of policy initiatives and collaborative synergy on sustainability and business growth of Indian SMEs

The influence of sustainability practices, especially those related to the environment and society in driving business growth is evident from the annual sustainability reports of big corporations. Also, there has been a plethora of research relating sustainability performance to the financial performance of these companies. However, in the case of small and medium-sized enterprises, a very limited research study has been done so far considering the societal and environmental aspects of their business operations. Small and medium enterprises (SMEs), especially those in the emerging economy have grossly neglected their responsibilities and obligations towards the environment and society. SMEs are considered as growth engines for any nation. However, literature has shown that a large percentage of SMEs across the world fail within a few years of their incorporation. This paper aims to verify the relationship between sustainability performance and business growth for SMEs in the developing economy. ,In the paper, the authors have tried to develop a model taking a sample of 200 SMEs from Indian leather and chemical sectors and find out how the factors like collaborative synergy and government policy initiatives impact the sustainability performance of small and medium firms and how in turn, their improved sustainability performance helps them to drive sustainable business growth. Data were mainly collected through primary survey and also from the company websites. ,Empirical results of the study reveal that both policy initiatives and collaborative synergy positively influence the firm’s sustainability performance and, in turn, the company’s business growth is positively impacted by their enhanced sustainability performance. Company size was found to have a moderating effect on this relationship. ,There are theoretical and conceptual papers elaborating on the importance of adoption of sustainability practices in SME business operations but no empirical study has been conducted to mathematically relate the factors of sustainability and business growth. The authors have tried to build a model relating the factors of sustainability improvement with those of the business growth of the firm and also verified the influence of control variables like company size on the proposed relationship.

In situ vertical characteristics of optical properties and heating rates of aerosol over Beijing

Abstract. Characterizing vertical profiles of aerosol optical properties is important because relying on only the surface or column-integrated measurements cannot unambiguously constrain the radiative impacts of aerosol. This study presents series of vertical profiles of in situ measured multi-wavelength optical properties of aerosols during three pollution events from November to December 2016 over the Beijing region. For all pollution events, the clean periods (CPs) before pollution initialization showed a higher scattering Ångström exponent (SAE) and a smaller asymmetry parameter (g) with relatively uniform vertical structures. The heavy pollution periods (HPs) showed an increased particle size, causing these parameters to vary in the opposite way. During the transition periods (TPs), regional transport of aged aerosols at higher altitudes was found. The Aerosol Robotic Network (AERONET) aerosol optical depth (AOD) matched the in situ measurements within 10 %; however the AERONET absorption optical depth (AAOD) was 10 %–20 % higher than the in situ measurements, and this positive discrepancy increased to 30 % at shorter wavelengths. The absorption of brown carbon (BrC) was identified by the increased-absorption Ångström exponent (AAE), and the heating rate of black carbon (BC) and BrC was estimated by computing the spectral absorption coefficient and actinic flux calculated by a radiative transfer model. BC and BrC had a heating rate of up to 0.18 and 0.05 K h−1 in the planetary boundary layer (PBL), respectively, during the pollution period. The fraction of BrC absorption increased from 12 % to 40 % in the PBL from the CP to the HP. Notably, a higher contribution of BrC heating was found above the PBL under polluted conditions. This study paints a full picture of shortwave heating impacts of carbonaceous aerosols during different stages of pollution events and highlights the increased contribution of BrC absorption especially at higher altitudes during pollution.
Business Strategies for Data Monetization: Deriving Insights from Practice

Although increases in available data have inspired companies ’ interest in creating and extracting value from it, many lack the insight and guidance to assess the potential data offer. To address this issue, we conduct a systematic literature review to create a universe of 102 real-world cases from diverse industries with regard to the use of data. Based on an analysis of these cases, this paper provides a set of 12 generic strategies for monetizing data, ranging from sole asset sale to strategically opening data and guaranteeing control. This study supports business practice by aggregating the wide range of established approaches of data monetization from practice for operational purposes. It advances theoretical understanding of value capturing from data and suggests important avenues for future work in this emerging field of research.
The Effects of Table Versus Formula Presentation Formats on Investors’ Judgment about Executive Compensation

Abstract We investigate how the data presentation format of executive compensation disclosures affects investors’ compensation- and investment-related judgment and decisions. We examine the effects of these formats and their underlying mechanisms via laboratory experiments. We compare bonus schemes presented in the table and formula formats and find an interaction effect between data presentation format and compensation favorability. When a manager receives unfavorable compensation due to missed performance targets, the table format is easier to understand than the formula format, whereas the latter appears more scientific than the former. These two effects work in opposite directions and therefore, result in an insignificant difference in approval ratings when the table, versus the formula, format is used. However, when the manager receives favorable compensation for beating performance targets, investors do not pay much attention to the disclosure’s understandability but still favor the formula format, as it has a scientific appearance. Therefore, we find that investors’ approval ratings are higher when using the formula format than the table format. We contribute to several research areas such as information understandability, the halo effect, compensation disclosures, and shareholder voting. Our findings also have practical implications for both managers and investors.
REDUCTION OF ESCHERICHIA COLI O157:H7 AND SALMONELLA ON FRESH-CUT PRODUCE BY CAPRYLIC ACID

Caprylic acid (CA) was evaluated for reducing Escherichia coli O157:H7 and Salmonella on fresh produce. Spinach, romaine lettuce and iceberg lettuce were inoculated with a cocktail of five E. coli O157:H7 or Salmonella strains, air dried for 30 min and then dipped in CA (10, 25 and 50 ppm) or chlorine (50 ppm) for 60 s. Treated leaves were analyzed for E. coli O157:H7 and Salmonella following treatment and during storage at 4C for 14 days. The CA treatment significantly reduced these pathogens on fresh produce compared to treatment with water (control) and chlorine. E. coli O157:H7 and Salmonella were undetectable in 25 and 50 ppm CA-treated leaves. E. coli O157:H7 and Salmonella were reduced further during storage. The antibacterial activity of CA (5 ppm) was dependent on exposure time. The CA could be used to kill E. coli O157:H7 and Salmonella on fresh produce. Practical Applications Foodborne illness outbreaks associated with fresh produce is a growing concern for the produce industry and regulatory agencies. Effective measures are needed to mitigate the foodborne pathogens at preharvest and postharvest level. Public health concern over the antimicrobial resistance and consumers' preference for chemical- or antibiotic-free food have led researchers to evaluate natural antimicrobials for food safety. We evaluated caprylic acid (CA) as a natural antimicrobial to reduce foodborne pathogens on fresh produce. The results reveal that CA can be used as a produce wash to reduce Escherichia coli O157:H7 and Salmonella on fresh produce.
Régulation de l'activité de Krox20 au cours de la mise en place du système nerveux central et périphérique

Au cours de ma these, j'ai etudie le role in vivo du facteur de transcription Krox20 durant le developpement precoce du cerveau posterieur des vertebres et durant le processus de myelinisation du systeme nerveux peripherique. Je me suis plus particulierement interessee aux mecanismes impliques dans la regulation de son activite via son interaction avec divers co-facteurs. Lors du developpement embryonnaire, le cerveau posterieur des vertebres, ou rhombencephale, presente une segmentation transitoire le long de l'axe antero-posterieur, aboutissant a la formation d'unites de differenciation neuronales. Le gene maitre Krox20, codant un facteur de transcription a doigts de zinc, est exprime precocement dans le rhombencephale et est necessaire a son developpement, ainsi qu'a l'organisation correcte des nerfs crâniens. Une etude structure-fonction de Krox20 realisee in vivo m'a permis de montrer que son activite au niveau du rhombencephale implique differents domaines de la proteine en fonction des cibles transcriptionnelles considerees. J'ai de plus etudie plus specifiquement le role de ses co-facteurs Nab et Hcf-1, montrant qu'ils jouent respectivement un role represseur et activateur de l'activite de Krox20 lors du developpement du rhombencephale. Krox20 est egalement un gene-cle du processus de myelinisation du systeme nerveux peripherique et diverses mutations l'affectant ont ete caracterisees chez des patients atteints de neuropathies demyelinisantes hereditaires, nommees maladies de Charcot-Marie-Tooth. J'ai genere une lignee de souris portant l'une de ces mutations, abolissant l'interaction entre Krox20 et les Nab. Ce modele murin, presentant des defauts similaires a ceux observes chez les patients humains, m'a permis de confirmer le role majeur de l'interaction entre Krox20 et les Nab dans le processus de myelinisation. J'ai par ailleurs pu montrer que l'hypomyelinisation observee reposait sur un phenotype complexe, lie a un retard du processus de myelinisation suivi d'une degradation de la myeline formee. Ceci suggere un role majeur de Krox20 et des Nab durant differentes etapes sequentielles de la myelinisation du systeme nerveux peripherique.

In the State Pharmacopoeia of the world necessarily present medicinal herbs morphological groups bark.1 Widely known for such raw materials as oak bark, buckthorn bark, bark viburnum, cinnamon bark, and others. The bark of the walnut is a medicinal plant raw materials, which is widely used in folk medicine as an anthelmintic funds, however, this raw material is currently poorly understood and is not represented in the pharmacopeia.2 However, medicinal herbs walnut bark is widely used in folk medicine. The bark of walnut harvested from young branches of a walnut with a diameter of not more than 3 cm.3 Young branches are cut during the formation of the tree crown, with no harm to the plant is not applied. The raw material is harvested, dried and further can be used as a drug in traditional medicine.4 Currently, the State Pharmacopoeia of the Russian Federation there is no pharmacopoeial article on medicinal plant raw materials bark of walnut.5,6 Thus, the study of indicators of quality of medicinal plants bark of walnut is relevant.
Breeding ecology of a burrow-nesting passerine, the white-rumped snowfinch "Montifringilla taczanowskii"

This work provides reproductive data about the white-rumped snowfinch Montifringilla taczanowskii and learn how avian life history respond to cavity-nesting and altitudinal gradients. The study was carried out in an alpine meadow in the northeastern Tibetan plateau, in Gahai National Nature Reserve (34° 14' N, 102° 20' E). During two breeding seasons individuals were marked and their nests contents were monitored. Nests were placed in pika Ochotona curzionae burrows and constructed by females only. Egglaying occurred between late April and early June. Some pairs (9 %) made two breeding attempts in a single year. Clutch size averaged 4.7 (2 - 6) and brood size at fledgling average was 3.5 (2 - 6). Females incubation lasts 9 to 15 days (13) and both sexes provide parental care until nestlings fledged at 18 to 24 days (21). Overall, 69 % of the nesting attempts produced at least one fledgling. The habit of cavity-nesting might allow the snowfinches to start breeding earlier, produce larger clutches, reduce nest attentiveness and enjoy a higher reproductive success than several local open-nesting passerines. Compared to their higher-altitude conspecifics, the lower-altitude snowfinches reach a greater annual productivity mainly through rearing larger broods.
