Librarians and the emerging research library: A case study of complex individual and organizational development.

The purpose of this case study was to increase the knowledge base of how research librarians experience and cope with the turbulence of change within their library system. This research also examined the issues that surround the organizational structures and leadership of transformative change in one research library. A library belonging to the Association of Research Libraries was selected for case study investigation. Seventeen librarians participated in on-site interviews, utilizing a protocol composed of a clustering technique and semi-structured interviewing. Instrumental case studies of each individual were then developed through a collective case method to present the intrinsic case study of the library system as an organization. Data were analyzed primarily through a complex systems theoretical framework while at the same time were grounded in a broad literature base of organizational, leadership, individual change, and library organizational development theories. The findings of the study include: the competing tensions between the physical and virtual environments, the search for professional meaning, coping with the experiences of professional change, the evolution of the organizational structure, and leadership as a shared experience. Analysis of the findings suggest: the emergence of a hypercritical state, the limiting nature of negative feedback, a complex systems framework for professional thinking, coping in the hypercritical organization, the emergence of disorder in the complex system, the blending of self-organizing systems with structural feedback mechanisms, and the complexity of leadership in the new research library

Command Your Keyboard

The goal of this project is to help people who are interested in learning the shortcuts available in the Adobe Premiere Pro video editing software. I will create a fun and interactive way for people to learn some of the fundamental shortcuts available by using the command symbol and another key located on the keyboard. Many people will have access to this tutorial program because I will make it available online through my Western Kentucky University web address. My project, Command Your Keyboard, will become a website using the software, Adobe Flash Professional. Along with the viewers of Command Your Keyboard, I will also learn a lot from completing this project. I will also have access to shortcut tutorials and by creating these videos and I will memorize other keyboard shortcuts. I will also gain more knowledge in Adobe Flash Professional by creating the website

From start-up to acquisition: Implications of financial investment trends for small- to medium-sized high-tech enterprises

The high-technology (high-tech) industry is a dynamic environment defined by both frequent changes in composition and a concentration of market power through consolidation. Operating as a new or small venture within this environment poses many complex challenges, especially when considering the financial resources needed to be successful. In their efforts to obtain financial resources, entrepreneurs often overlook how the choice and pattern of investment funding to maintain a growth path can later affect a successful entrepreneurial exit. Exit via acquisition for small- to medium-sized technology enterprises (SMTEs) is a strong area of interest given firms in the U.S. high-tech industry experience the fastest growth rates and have been the target of over $400 billion in deal volume and 20% of all merger and acquisition (M&A) transactions in the last twenty years. Much of this M&A activity is conducted by five prominent firms, Alphabet, Amazon, Apple, Facebook, Microsoft, commonly referred to as the Fearsome Five or the “FANGS”. However, as there has been only limited research examining this unique M&A context, in this study we explore the investment funding factors influencing exit via acquisition by the Fearsome Five. We highlight questions and potential concerns for SMTEs given the trends in financial investments and increasing market power

Population Reproductive Statistics of Millet Head Miner (Lepidoptera: Noctuidae) Reared in a Laboratory in Niger

Net reproductive rates and cohort generation times are tabulated for pearl millet head miner (Heliocheilus albipunctella) reared on 4 diets (Bio-Serv® 9782 and 3 pearl millet-based diets) at 24, 26, 28 or 30°C. The highest R0 values of 5.84 and 4.33 females per female were estimated when the head miners were fed Bio-Serv® at 30° and early exserted millet at 24°, respectively. Tc tended to be shortest at 26 and 28°

Field Evaluation of Fecundity, Longevity, and Oviposition Period of Millet Head Miner (Lepidoptera: Noctuidae) in Niger

The factors regulating Heliocheilus albipunctella development and abundance on pearl millet were investigated in field experiments in Niger. H. albipunctella in exclusion cages survived between 2 and 6 days and the oviposition period lasted 1-4 days. The mean number of eggs oviposited per female was 29.6. In experiments in 1997, the number of eggs oviposited varied with the pearl millet sowing date and was greatest on millet sown on 4 July (21.6 eggs oviposited per day). These data will contribute to the greater understanding of H. albipunctella biology necessary for its control

Cultural value orientations, internalized homophobia, and accommodation in romantic relationships

In the present study, we examined the impact of cultural value orientations (i.e., the personally oriented value of individualism, and the socially oriented values of collectivism, familism, romanticism, and spiritualism) on accommodation (i.e., voice and loyalty, rather than exit and neglect, responses to partners' anger or criticism) in heterosexual and gay relationships; and we examined the impact of internalized homophobia (i.e., attitudes toward self, other, and disclosure) on accommodation specifically in gay relationships. A total of 262 heterosexuals (102 men and 162 women) and 857 gays (474 men and 383 women) participated in the present study. Consistent with hypotheses, among heterosexuals and gays, socially oriented values were significantly and positively related to accommodation (whereas the personally oriented value of individualism was unrelated to accommodation); and among gays in particular, internalized homophobia was significantly and negatively related to accommodation. Implications for the study of heterosexual and gay relationships are discussed. © 2005 by The Haworth Press, Inc. All rights reserved

Is Perioperative Hypothermia a Risk Factor for Post-Cesarean Infection?

Objective: To determine whether hypothermia during Cesarean delivery is a risk factor for postoperative infection. Methods: An historical cohort investigation was conducted on all women delivered by Cesarean at our center during 2001. Initial recovery-room temperature, taken via the oral or axillary route, was used as a surrogate for intraoperative temperature. Adding 0.5(°)C to axillary temperatures generated oral temperature equivalents. Women with chorioamnionitis were excluded, as were those with an initial recovery-room temperature that exceeded 37.9(°)C or was recorded more than 20 minutes after the end of surgery. Prophylactic antibiotics (cefazolin, 1 g) were given during Cesarean delivery. Results: A total of 42 women (7.6%) were diagnosed with postoperative infections. Infections included endometritis (n= 25), wound abscess (n = 7), wound cellulitis (n = 7) and urinary tract infection (UTI) (n = 4). No cases of septic pelvic thrombophlebitis or pelvic abscess occurred. One woman had both endometritis and a UTI. Mean temperatures were higher, rather than lower, for women who subsequently had postoperative infections compared with those who did not (36.4 ± 0.8(°)Cvs. 35.9 ± 0.7(°)C; p < 0.001). Mean temperatures for the various postoperative infections were as follows: endometritis, 36.5 ± 0.8(°)C (p < 0.001 vs. uninfected group); wound abscess 36.0 ± 0.8(°)C (p = 0.63); wound cellulitis, 36.3 ± 0.6(°)C (p = 0.14); UTI, 36.7 ± 0.9(°)C (p = 0.04). Conclusions: Women who develop post-Cesarean infections have higher initial recovery-room temperatures than those who do not develop such infections. This suggests the presence of subclinical infection at the time of Cesarean. Evaluating whether intraoperative warming has any role during Cesarean delivery requires a randomized clinical trial

Alterations in ethanol-induced behaviors and consumption in knock-in mice expressing ethanol-resistant NMDA receptors

Ethanol's action on the brain likely reflects altered function of key ion channels such as glutamatergic N-methyl-D-aspartate receptors (NMDARs). In this study, we determined how expression of a mutant GluN1 subunit (F639A) that reduces ethanol inhibition of NMDARs affects ethanol-induced behaviors in mice. Mice homozygous for the F639A allele died prematurely while heterozygous knock-in mice grew and bred normally. Ethanol (44 mM; ∼0.2 g/dl) significantly inhibited NMDA-mediated EPSCs in wild-type mice but had little effect on responses in knock-in mice. Knock-in mice had normal expression of GluN1 and GluN2B protein across different brain regions and a small reduction in levels of GluN2A in medial prefrontal cortex. Ethanol (0.75-2.0 g/kg; IP) increased locomotor activity in wild-type mice but had no effect on knock-in mice while MK-801 enhanced activity to the same extent in both groups. Ethanol (2.0 g/kg) reduced rotarod performance equally in both groups but knock-in mice recovered faster following a higher dose (2.5 g/kg). In the elevated zero maze, knock-in mice had a blunted anxiolytic response to ethanol (1.25 g/kg) as compared to wild-type animals. No differences were noted between wild-type and knock-in mice for ethanol-induced loss of righting reflex, sleep time, hypothermia or ethanol metabolism. Knock-in mice consumed less ethanol than wild-type mice during daily limited-access sessions but drank more in an intermittent 24 h access paradigm with no change in taste reactivity or conditioned taste aversion. Overall, these data support the hypothesis that NMDA receptors are important in regulating a specific constellation of effects following exposure to ethanol. © 2013 den Hartog et al

Intravenous Aviptadil and Remdesivir for Treatment of COVID-19-Associated Hypoxaemic Respiratory Failure in the USA (Tesico): A Randomised, Placebo-Controlled Trial

BACKGROUND: There is a clinical need for therapeutics for COVID-19 patients with acute hypoxemic respiratory failure whose 60-day mortality remains at 30-50%. Aviptadil, a lung-protective neuropeptide, and remdesivir, a nucleotide prodrug of an adenosine analog, were compared with placebo among patients with COVID-19 acute hypoxaemic respiratory failure. METHODS: TESICO was a randomised trial of aviptadil and remdesivir versus placebo at 28 sites in the USA. Hospitalised adult patients were eligible for the study if they had acute hypoxaemic respiratory failure due to confirmed SARS-CoV-2 infection and were within 4 days of the onset of respiratory failure. Participants could be randomly assigned to both study treatments in a 2 × 2 factorial design or to just one of the agents. Participants were randomly assigned with a web-based application. For each site, randomisation was stratified by disease severity (high-flow nasal oxygen or non-invasive ventilation vs invasive mechanical ventilation or extracorporeal membrane oxygenation [ECMO]), and four strata were defined by remdesivir and aviptadil eligibility, as follows: (1) eligible for randomisation to aviptadil and remdesivir in the 2 × 2 factorial design; participants were equally randomly assigned (1:1:1:1) to intravenous aviptadil plus remdesivir, aviptadil plus remdesivir matched placebo, aviptadil matched placebo plus remdesvir, or aviptadil placebo plus remdesivir placebo; (2) eligible for randomisation to aviptadil only because remdesivir was started before randomisation; (3) eligible for randomisation to aviptadil only because remdesivir was contraindicated; and (4) eligible for randomisation to remdesivir only because aviptadil was contraindicated. For participants in strata 2-4, randomisation was 1:1 to the active agent or matched placebo. Aviptadil was administered as a daily 12-h infusion for 3 days, targeting 600 pmol/kg on infusion day 1, 1200 pmol/kg on day 2, and 1800 pmol/kg on day 3. Remdesivir was administered as a 200 mg loading dose, followed by 100 mg daily maintenance doses for up to a 10-day total course. For participants assigned to placebo for either agent, matched saline placebo was administered in identical volumes. For both treatment comparisons, the primary outcome, assessed at day 90, was a six-category ordinal outcome: (1) at home (defined as the type of residence before hospitalisation) and off oxygen (recovered) for at least 77 days, (2) at home and off oxygen for 49-76 days, (3) at home and off oxygen for 1-48 days, (4) not hospitalised but either on supplemental oxygen or not at home, (5) hospitalised or in hospice care, or (6) dead. Mortality up to day 90 was a key secondary outcome. The independent data and safety monitoring board recommended stopping the aviptadil trial on May 25, 2022, for futility. On June 9, 2022, the sponsor stopped the trial of remdesivir due to slow enrolment. The trial is registered with ClinicalTrials.gov, NCT04843761. FINDINGS: Between April 21, 2021, and May 24, 2022, we enrolled 473 participants in the study. For the aviptadil comparison, 471 participants were randomly assigned to aviptadil or matched placebo. The modified intention-to-treat population comprised 461 participants who received at least a partial infusion of aviptadil (231 participants) or aviptadil matched placebo (230 participants). For the remdesivir comparison, 87 participants were randomly assigned to remdesivir or matched placebo and all received some infusion of remdesivir (44 participants) or remdesivir matched placebo (43 participants). 85 participants were included in the modified intention-to-treat analyses for both agents (ie, those enrolled in the 2 x 2 factorial). For the aviptadil versus placebo comparison, the median age was 57 years (IQR 46-66), 178 (39%) of 461 participants were female, and 246 (53%) were Black, Hispanic, Asian or other (vs 215 [47%] White participants). 431 (94%) of 461 participants were in an intensive care unit at baseline, with 271 (59%) receiving high-flow nasal oxygen or non-invasive ventiliation, 185 (40%) receiving invasive mechanical ventilation, and five (1%) receiving ECMO. The odds ratio (OR) for being in a better category of the primary efficacy endpoint for aviptadil versus placebo at day 90, from a model stratified by baseline disease severity, was 1·11 (95% CI 0·80-1·55; p=0·54). Up to day 90, 86 participants in the aviptadil group and 83 in the placebo group died. The cumulative percentage who died up to day 90 was 38% in the aviptadil group and 36% in the placebo group (hazard ratio 1·04, 95% CI 0·77-1·41; p=0·78). The primary safety outcome of death, serious adverse events, organ failure, serious infection, or grade 3 or 4 adverse events up to day 5 occurred in 146 (63%) of 231 patients in the aviptadil group compared with 129 (56%) of 230 participants in the placebo group (OR 1·40, 95% CI 0·94-2·08; p=0·10). INTERPRETATION: Among patients with COVID-19-associated acute hypoxaemic respiratory failure, aviptadil did not significantly improve clinical outcomes up to day 90 when compared with placebo. The smaller than planned sample size for the remdesivir trial did not permit definitive conclusions regarding safety or efficacy. FUNDING: National Institutes of Health
