Proposed use of spatial mortality assessments as part of the pesticide evaluation scheme for vector control

2013

Background: The WHO Pesticide Evaluation Scheme to evaluate the efficacy of insecticides does not include the testing of a lethal effect at a distance. A tool was developed to evaluate the spatial mortality of an insecticide product against adult mosquitoes at a distance under laboratory and field conditions. Operational implications are discussed. Methods: Insecticide paint, Inesfly 5A IGR (TM), containing two organophosphates (OPs): chlorpyrifos and diazinon, and one insect growth regulator (IGR): pyriproxyfen, was the product tested. Laboratory tests were performed using "distance boxes" with surfaces treated with one layer of control or insecticide paint at a dose of 1 kg/6 sq m. Field …

Digital datafication of education

2021

Tässä kriittisessä esseessä luon yleiskatsauksen koulutuksen digitaalisen datafikaation erilaisiin muotoihin ja merkityksiin erityisesti kotimaisessa kontekstissa. Esseessä käyn läpi datafikaation suhdetta muihin koulutusta ohjaaviin trendeihin, erityisesti digitalisaatioon, oppimiskeskeisyyteen ja tulosvastuullisuuteen. Lisäksi tarkastelen datan ja datan diskursiivisen tuottamisen välistä epäsuhtaa, josta jatkan koulun dataintensiivisten käytäntöjen kautta tapahtuvan jatkuvan datankeruun luonnollistumisen tarkasteluun. Viimeisessä temaattisessa osiossa jäsennän elinikäisen oppimisen ideologian ja datafikaation välistä suhdetta. Esseen lopuksi esitän monilukutaidon pedagogiikkaan tukeutuen …

Hydraulic kinetics of the graft union in different Olea europaea L. scion/rootstock combinations

2007

The hydraulic resistance of young olive trees grafted on rootstocks with contrasting size-controlling potential was measured 30, 90, 360 and 480 days after grafting. Olive (Olea europaea L.) clones inducing plant vigorous growth (Leccino ‘Minerva’, LM) or dwarfing (Leccino ‘Dwarf’, LD) were studied in different scion/rootstock combinations (LD/LD, LD/LM, LM/LD, LM/LM). Plants growing on LD root systems developed lower leaf surface areas (about 50% less) than plants grafted on LM rootstocks. Graft union represented the largest fraction (up to 85%) of whole-plant hydraulic resistance 30 days after grafting, and still represented an important fraction of it 2 months later (40–55%). Four-hundre…

Volatility Transmission Models: A Survey

2005

This study reviews the literature on volatility transmission in order to determine what we have learnt about the different methodologies applied. In particular, GARCH, regime switching and stochastic volatility models are analysed. In addition, this study covers several concrete aspects such as their scope of application, the overlapping problem, the concept of efficiency and asymmetry modelling. Finally, emerging topics and unanswered questions are identified, serving as an agenda for future research.

The Essence of Dynamic Capabilities and their Measurement

2016

The growing popularity of explaining firm performance through dynamic capabilities has motivated plenty of conceptual development in the field. However, empirical approaches to measuring dynamic capabilities have so far not been under comprehensive scrutiny. The authors; purpose is to assess the extent to which different ways of measuring dynamic capabilities in quantitative studies correspond to the theoretical essence of the concept, and develop recommendations for future research. They find that four types of operationalizations have been used: (1) managers’ evaluations; (2) financial data; (3) company's experience, actions and performance; and (4) managers’ or employees’ experience, act…

Molecular Characterization of a Long Term Survivor Double Metastatic Non Small Sell Lung Cancer and Pancreatic Ductal Adenocarcinoma Treated with Gef…

2019

Management of multiple primary cancers, a not so infrequent event in oncology practice, is a critical issue due to the lack of literature . In this study, we reported the case of a patient with metachronous double metastatic non small cell lung cancer (NSCLC) and pancreatic ductal adenocarcinoma (PDAC) who received gefitinib in combination with gemcitabine plus nab-paclitaxel and with mFOLFOX6 in first and second line, respectively. She achieved a progression free survival and an overall survival (OS) of 28 months for NSCLC and PFS-1 and OS of 20 and 13 months, respectively for PDAC. Moreover, the combination of gefitinib and chemotherapies treatments displayed a good safety profile. Given …

Student Engagement, Truancy, and Cynicism

2021

Abstract Truancy in upper secondary education is a widespread problem, which contributes significantly to school dropout risk. However, the underlying mechanisms of truancy have remained unstudied. This longitudinal study of 1853 Finnish students examined how initial levels and changes in student engagement from primary (Grade 6) to lower secondary school (Grades 7 and 9) predicted truancy in upper secondary education, and whether cynicism (losing interest in school) mediated the relationship between engagement and truancy. Growth curve models showed that high engagement levels in primary school and increases in engagement over time predicted less truancy in upper secondary education. Cynic…

A RAPID METHOD FOR CALCULATING THE TRANSVERSAL STRAIN IN THE MOIRE TECHNIQUE ALONG SECTIONS OF SYMMETRY

1970

An approximate rapid method is described for calculating in the moire technique the transversal strain directly from the longitudinal strain distribution across sections of symmetry. The method is based on evaluation of the load transmitted through the section and is corroborated by two examples.

Phylogeny and Mycotoxin Characterization of Alternaria Species Isolated from Wheat Grown in Tuscany, Italy

2018

Wheat, the main source of carbohydrates worldwide, can be attacked by a wide number of phytopathogenic fungi, included Alternaria species. Alternaria species commonly occur on wheat worldwide and produce several mycotoxins such as tenuazonic acid (TA), alternariol (AOH), alternariol-monomethyl ether (AME), and altenuene (ALT), provided of haemato-toxic, genotoxic, and mutagenic activities. The contamination by Alternaria species of wheat kernels, collected in Tuscany, Italy, from 2013 to 2016, was evaluated. Alternaria contamination was detected in 93 out of 100 field samples, with values ranging between 1 and 73% (mean of 18%). Selected strains were genetically characterized by multi-locus…
