An airline connection builder using maximum connection lag with greedy parameter selection
2014
Abstract This paper introduces a methodology for designing an airline connection builder (CB) and adjusting its parameter settings. The objective of the proposed CB is to construct relevant connections that attract passenger demand while avoiding operationally infeasible and commercially irrelevant connections. Using worldwide MIDT booking data, we examined the sensitivity of CB results to the setting of the standard CB parameters maximum connection time and geographical detour. We demonstrated that CB performance can be increased by replacing these two parameters with connection lag, a measure that combines the impact of connection time with geographical detour on the total travel time of …
Attitudes of referees in a multidisciplinary journal: An empirical analysis
2016
This paper looks at 10 years of reviews in a multidisciplinary journal, The Journal of Artificial Societies and Social Simulation (JASSS), which is the flagship journal of social simulation. We measured referee behavior and referees' agreement. We found that the disciplinary background and the academic status of the referee have an influence on the report time, the type of recommendation and the acceptance of the reviewing task. Referees from the humanities tend to be more generous in their recommendations than other referees, especially economists and environmental scientists. Second, we found that senior researchers are harsher in their judgments than junior researchers, and the latter ac…
Students' Information Literacy Development as a Guarantee of Qualitative Studies
2015
Publication devoted to information literacy development updates. Information literacy competencies as the basis for the success of a human life takes on a special significance in higher education teaching. Success of this process is driven by university cooperation partners: teachers, librarians and administrations work. Teachers implement information literacy development methods courses, librarians responsible for information resources in institution make up their own training system, but the administration - facilitates the implementation of information literacy and financial support. Competencies based on governmental, professional or institutional defined standards, which can provide an…
Validación de un cuestionario para evaluar el funcionamiento de las bibliotecas escolares
2018
La biblioteca escolar ha adquirido en los últimos años un nuevo protagonismo, convirtiéndose en un espacio de aprendizaje fundamental para la enseñanza de las distintas áreas y materias y el fomento de competencias en el alumnado. El objetivo de este trabajo es validar un cuestionario diseñado ad hoc para evaluar el funcionamiento y las formas de uso e incorporación de la biblioteca escolar a la actividad pedagógica diaria. Para ello se aplicó el cuestionario a una muestra aleatoria de 4.177 alumnas y alumnos de 358 centros de Educación Primaria, Secundaria y Postobligatoria, se calculó su fiabilidad mediante la prueba de Alfa de Cronbach y se realizó un análisis factorial exploratorio. Los…
Latvijas Universitātes Bibliotēka periodisko izdevumu publikācijās (1941-1990): bibliogrāfiskais rādītājs
2022
Bibliogrāfiskajā rādītājā apkopotas publikācijas preses izdevumos, kurās minēta LU Bibliotēka no 1941. līdz 1990. gadam (ieskaitot), kad Pētera Stučkas Latvijas Valsts Universitāte (turpmāk LVU) atgūst savu iepriekšējo nosaukumu – Latvijas Universitāte. Bibliogrāfiskā rādītāja izstrādē izmantots Latvijas Nacionālās digitālās bibliotēkas portāls periodika.lv. Rezultāti tika atlasīti, izvēloties pētījumam nepieciešamo laika periodu. Lai apkopotu bibliogrāfiskajam rādītājam atbilstošus rakstus, tika veikta visu publikāciju kvalitatīvā satura analīze. Bibliogrāfiskie ieraksti kārtoti hronoloģiski, ņemot vērā būtiskus vēsturiskus atskaites punktus un bibliotēkas mainīgo struktūru.
High-to-low (Regional) fertility transitions in a peripheral european country: The contribution of exploratory time series analysis
2021
Diachronic variations in demographic rates have frequently reflected social transformations and a (more or less evident) impact of sequential economic downturns. By assessing changes over time in Total Fertility Rate (TFR) at the regional scale in Italy, our study investigates the long-term transition (1952–2019) characteristic of Mediterranean fertility, showing a continuous decline of births since the late 1970s and marked disparities between high- and low-fertility regions along the latitude gradient. Together with a rapid decline in the country TFR, the spatiotemporal evolution of regional fertility in Italy—illustrated through an exploratory time series statistical approach—outlines th…
Evaluation of T7 and lambda phage display systems for survey of autoantibody profiles in cancer patients.
2008
In the current study we attempted to evaluate the suitability of T7 Select 10-3b and lambdaKM8 phage display systems for the identification of antigens eliciting B cell responses in cancer patients and the production of phage-displayed antigen microarrays that could be exploited for the monitoring of autoantibody profiles. Members of 15 tumour-associated antigen (TAA) families were cloned into both phage display vectors and the TAA mini-libraries were immunoscreened with 22 melanoma patients' sera resulting in the detection of reactivity against members of 5 antigen families in both systems, yet with variable sensitivity. T7 phage display system showed greater sensitivity for the detection …
Identification of a polyketide synthase gene (pksP) of Aspergillus fumigatus involved in conidial pigment biosynthesis and virulence.
1998
Aspergillus fumigatus is an important pathogen of the immunocompromised host causing pneumonia and invasive disseminated disease with high mortality. Previously, we identified a mutant strain (white, W) lacking conidial pigmentation and, in addition, the conidia showed a smooth surface morphology, whereas wild-type (WT) conidia are grey-green and have a typical ornamentation. W conidia appeared to be less protected against killing by the host defence, e.g., were more susceptible to oxidants in vitro and more efficiently damaged by human monocytes in vitro than WT conidia. When compared to the WT, the W mutant strain showed reduced virulence in a murine animal model. Genetic analysis suggest…
Lyme neuroborreliosis with encephalitis; a systematic literature review and a Scandinavian cohort study
2022
Background Lyme neuroborreliosis (LNB) presenting with encephalitis is rare and scarcely described. Objectives To describe the available literature on LNB encephalitis and to characterize this patient group through a Scandinavian retrospective cohort study. Data sources Medline, Embase, Scopus, Cochrane library. Study eligibility criteria There was no discrimination on study type, time of publication or language. Participants Review: All articles with definite LNB and confirmed/possible encephalitis. Cohort: LNB cohorts from Denmark, Sweden and Norway 1990–2019 were screened for patients with encephalitis. Methods Review: Adhering to PRISMA guidelines; two authors extracted reviews and asse…
Consensus document on controversial issues for the treatment of hospital-associated pneumonia
2010
Background: Hospital-associated pneumonia (HAP) remains an important cause of morbidity and mortality despite advances in antimicrobial therapy. Many aspects of the treatment of HAP caused by multi-resistant Gram-positive microorganisms have been extensively studied, but controversial issues remain. Controversial issues: The aim of this GISIG (Gruppo Italiano di Studio sulle Infezioni Gravi) working group – a panel of multidisciplinary experts – was to define recommendations for some controversial issues using an evidence-based and analytical approach. The controversial issues were: (1) Is combination antibiotic therapy or monotherapy more effective in the treatment of HAP? (2) What role do…
