Predator-Induced Plasticity on Warning Signal and Larval Life-History Traits of the Aposematic Wood Tiger Moth, Arctia plantaginis
2021
Correction Frontiers in Ecology and Evolution Volume 9 Article Number 737651 DOI 10.3389/fevo.2021.737651 Published JUL 29 2021 Predator-induced plasticity in life-history and antipredator traits during the larval period has been extensively studied in organisms with complex life-histories. However, it is unclear whether different levels of predation could induce warning signals in aposematic organisms. Here, we investigated whether predator-simulated handling affects warning coloration and life-history traits in the aposematic wood tiger moth larva, Arctia plantaginis. As juveniles, a larger orange patch on an otherwise black body signifies a more efficient warning signal against predators…
Vecāku uzraudzība, pusaudžu pašcieņa un delinkvences biežums, viena un divu vecāku ģimenēs
2015
Pētījuma mērķis ir izpētīt vecāku uzraudzības veidu un pusaudžu pašcieņas saistību ar delinkvences biežumu ģimenēs, kur bērnu audzina viens vecāks, un ģimenēs, kur bērnu audzina divi vecāki. Pētījumā piedalījās 103 pusaudži, 45 zēni un 58 meitenes, vidējais vecums 14,7 gadi, kuri veica trīs aptaujas: „Delinkventas uzvedības biežuma aptauja” (Frequency of Delinquent Behavior, Dahlberg, Toal & Behren, 1998), „Rozenberga pašcieņas aptauja” (Rosenberg Self-Esteem Scale, Rosenberg, 1965) un „Vecāku uzraudzības aptauja” (Parental Monitoring Scale, Stattin & Kerr, 2000), kura ietvēra vecāku informētību, pusaudžu atklātību, vecāku kontroli un kontroles izjūtu. Pētījumā tika noskaidrots, ka divu bio…
Henkilökohtaista brändäystä vai yrityksen "työlähettiläisyyttä" : asiantuntijan verkkoyhteisöpalvelu LinkedInin käyttö
2016
Tämän ajan puhutuimpiin sosiaalisen median markkinointikeinoihin kuuluu työntekijälähettiläisyys. Työntekijälähettilään odotetaan edistävän yrityksensä positiivista mainetta esiintyessään sosiaalisessa mediassa. Tässä tutkimuksessa on tarkoitus selvittää, onko asiantuntijan LinkedInissä esiintymisen tarkoitus itsensä esittäminen ja brändäys vai työantajayrityksensä markkinointi. Lisäksi tutkimuksessa selvitetään, mitä vaikutteita asiantuntijan LinkedInin käytön taustalla on. Tutkielman kirjallisuuskatsauksen ensimmäisessä osassa tarkastellaan LinkedIniä sosiaalisena mediana ja verkkoyhteisöpalveluna. Kirjallisuuden toinen osa käsittelee teknologian käyttöön vaikuttavia tekijöitä. Tutkimusai…
Jauniešu delinkventas uzvedības biežuma saistība ar bērna pārraudzību un pielāgošanos vienaudžiem
2022
Jauniešu delinkvence, tās sekas uz sabiedrību un jauniešu veselību, un labklājību vienmēr ir bijuši nozīmīgi temati. Kā arī delinkvences veicinošie riska faktori, kas attiecas uz jaunieša apkārtējo vidi – ģimene un vienaudžu ietekme. Bakalaura mērķis ir noskaidrot, kādas saistības ir starp delinkventu uzvedību ar bērna pārraudzību un pielāgošanos vienaudžiem jauniešu izlasē vecumā 14 – 18 gadiem. Pētījuma izlasi veido 133 jaunieši (M vecums = 16,2). Izlasi pārstāvēja 74 meitenes un 59 zēni. Šī darba ietvaros tika izmantotas trīs pētījuma metodes: Vienaudžu pielāgošanās aptauja, Vecāku pārraudzības aptauja un Delinkventas uzvedības biežuma aptauja. Bakalaura darba rezultāti norāda, ka vienau…
Sustaining Attention for a Prolonged Duration Affects Dynamic Organizations of Frequency-Specific Functional Connectivity
2020
Sustained attention encompasses a cascade of fundamental functions. The human ability to implement a sustained attention task is supported by brain networks that dynamically formed and dissolved through oscillatory synchronization. The decrement of vigilance induced by prolonged task engagement affects sustained attention. However, little is known about which stage or combinations are affected by vigilance decrement. Here, we applied an analysis framework composed of weighted phase lag index (wPLI) and tensor component analysis (TCA) to an EEG dataset collected during 80 min sustained attention task to examine the electrophysiological basis of such effect. We aimed to characterize the phase…
Single amino acid substitutions in the glycoprotein B carboxy terminus influence the fusion from without property of herpes simplex virus type 1.
1995
Syncytial mutations of herpes simplex virus type 1 (HSV-1) strains ANG, ANG path, HFEM, tsB5 and HSZP cause extensive cell fusion and were mapped to the cytoplasmic domain of glycoprotein B (gB), within the syn 3 locus. These strains are so far the only ones which show the phenotype ‘fusion from without’ (FFWO): 60 min after infection with high m.o.i., cells in a tissue culture are fused without transcription and translation of the viral genome. In this report we detected, using the recombinants 27/III and K-7, that an amino acid exchange from Ala to Val at aa position 854 of gB is the main determinant for FFWO activity of strains ANG, ANG path and recombinant K-7. The transfer of this muta…
Cybersecurity Attacks on Software Logic and Error Handling Within ADS-B Implementations: Systematic Testing of Resilience and Countermeasures
2022
Automatic Dependent Surveillance-Broadcast (ADS-B) is a cornerstone of the next-generation digital sky and is now mandated in several countries. However, there have been many reports of serious security vulnerabilities in the ADS-B architecture. In this paper, we demonstrate and evaluate the impact of multiple cyberattacks on ADS-B via remote radio frequency links that affected various network, processing, and display subsystems used within the ADS-B ecosystem. Overall we implemented and tested 12 cyberattacks on ADS-B in a controlled environment, out of which 5 attacks were presented or implemented for the first time. For all these attacks, we developed a unique testbed that consisted of 1…
Alcohol use, aquatic injury, and unintentional drowning : A systematic literature review
2018
Issues Drowning is a global public health issue, and there is a strong association between alcohol and risk of drowning. No previous systematic review known to date has identified factors associated with alcohol use and engagement in aquatic activities resulting in injury or drowning (fatal and non‐fatal). Approach Literature published from inception until 31 January 2017 was reviewed. Included articles were divided into three categories: (i) prevalence and/or risk factors for alcohol‐related fatal and non‐fatal drowning and aquatic injury, (ii) understanding alcohol use and aquatic activities, and (iii) prevention strategies. Methodological quality of studies was assessed using National He…
Development of an immunochromatographic assay based on carbon nanoparticles for the determination of the phytoregulator forchlorfenuron
2013
Rapid analytical methods enabling the determination of diverse targets are essential in a number of research areas, from clinical diagnostics to feed and food quality and safety. Herein, the development of a quantitative immunochromatographic assay for the detection of the synthetic phytoregulator forchlorfenuron (CPPU) is described. The competitive lateral flow immunoassay (LFIA) was based on the immobilization onto a nitrocellulose membrane of an ovalbumin-CPPU conjugate (test line) and on the use of an immunodetection ligand consisting of carbon nanoparticles labeled with an anti-CPPU monoclonal antibody through interaction with a secondary antibody. The presence of CPPU in horticultural…
