Estados Unidos y la guerra por el desarrollo: el control de la natalidad en Chile, 1960-1970

Bajo el paradigma de modernización y desarrollo norteamericano -y en un contexto de Guerra Fría-, durante la década de 1960 se adecuaron a la realidad chilena programas de control de natalidad que no sólo buscaron disminuir las altas tasas de mortalidad materno infantil, sino que además respondieron al proyecto de seguridad hemisférica norteamericana de contención a posibles revoluciones populares en países del Tercer Mundo.

Who is in charge? An L2 Discourse Intonation Study on Four Prosodic Parameters to Exert the Pragmatic Function of Dominance and Control in the Context of L2 Non-specialist Public Speaking

This paper reports the findings from a study of the learning of English intonation by Spanish speakers within the discourse mode of L2 oral presentation. The purpose of this experiment is, firstly, to compare four prosodic parameters before and after an L2 discourse intonation training programme and, secondly, to confirm whether subjects, after the aforementioned L2 discourse intonation training, are able to match the form of these four prosodic parameters to the discourse-pragmatic function of dominance and control. The study designed the instructions and tasks to create the oral and written corpora and Brazil’s Pronunciation for Advanced Learners of English was adapted for the pedagogical aims of the present study. The learners’ pre- and post-tasks were acoustically analysed and a pre / post- questionnaire design was applied to interpret the acoustic analysis. Results indicate most of the subjects acquired a wider choice of the four prosodic parameters partly due to the prosodically-annotated transcripts that were developed throughout the L2 discourse intonation course. Conversely, qualitative and quantitative data reveal most subjects failed to match the forms to their appropriate pragmatic functions to express dominance and control in an L2 oral presentation.

Heeft Interactice control invloed op de rol van de controller?

De Hoofdvraag van dit onderzoek is: Is er een relatie tussen de lever of control Interactive control en het vervullen van de controllerrol business partner? Dit onderzoek is gebaseerd op de dataset verkregen uit de controllerenquête 2013, uitgevoerd in opdracht van de Open Universiteit (Bork & van der Wal, 2014). Vanuit het literatuuronderzoek is het duidelijk: de rol business partner is een zeer gewenste rol voor controllers. Daarnaast is er in de literatuur een verband te vinden tussen de rol business partner en de lever of control Interactive control. De factor- en clusteranalyse zoals beschreven door Bork & van der Wal (2014), resulteerde in de identificatie van twee type controllers. In dit uitgebreide onderzoek is TYPE II geïdentificeerd als business partner, omdat hij/zij activiteitencombinaties uitvoert die gerelateerd zijn aan strategie, analyseren, het management ondersteunen in besluitvorming, advisering, change management en de organisatie vertegenwoordigen. 36% van de populatie van aan Nederlandse Universiteiten afgestudeerde controllers die ook werkzaam zijn als controller vervullen een rol grotendeels gelijk aan de rol business partner. De vervulling van de rol (TYPE II) is niet puur business partner. Vervaardigen en organiseren van rapportagestromen zijn ook activiteiten die uitgevoerd worden door TYPE II. Daarnaast voert TYPE I activiteiten als change en risk management uit, volgens de definitie zou de business partner deze activiteiten uit moeten voeren. De rol business partner wordt uitgevoerd, maar nog niet in de optimale vorm zoals aangegeven in de theorie. De logistische regressieanalyse op de dataset laat zien dat geen van de levers of control een significante trigger is voor het uitvoeren van een van de twee types controllerrollen (Bork & van der Wal, 2014). Dit verdiepende onderzoek concentreert zich op de relatie tussen de lever of control Interactive control en de zes activiteitencombinaties (factoren) in plaats van de twee clusters (TYPE I & II). De statistische analyses bevestigen de uitkomsten het onderzoek van Bork & van der Wal (2014). Er is geen significantie tussen Interactive control en de factoren die behoren bij de business partner rol. De hoofdvraag moet ontkennend beantwoord worden, er is geen relatie tussen de lever of control Interactive control en de controllerrol business partner. Een paar beperkingen van het onderzoek richten zich op de vragenlijst over de levers of control: is het de juiste vragenlijst voor dit onderzoek en meet deze vragenlijst de levers of control van controllers? Vervolg onderzoek kan zich richten op bovenstaande beperking. Daarnaast zijn er uit het onderzoek van Bork & van der Wal (2014) triggers naar voren gekomen die verder onderzocht kunnen worden.

Shape-based compliance control for snake robots

I serpenti robot sono una classe di meccanismi iper-ridondanti che appartiene alla robotica modulare. Grazie alla loro forma snella ed allungata e all'alto grado di ridondanza possono muoversi in ambienti complessi con elevata agilità. L'abilità di spostarsi, manipolare e adattarsi efficientemente ad una grande varietà di terreni li rende ideali per diverse applicazioni, come ad esempio attività di ricerca e soccorso, ispezione o ricognizione. I robot serpenti si muovono nello spazio modificando la propria forma, senza necessità di ulteriori dispositivi quali ruote od arti. Tali deformazioni, che consistono in movimenti ondulatori ciclici che generano uno spostamento dell'intero meccanismo, vengono definiti andature. La maggior parte di esse sono ispirate al mondo naturale, come lo strisciamento, il movimento laterale o il movimento a concertina, mentre altre sono create per applicazioni specifiche, come il rotolamento o l'arrampicamento. Un serpente robot con molti gradi di libertà deve essere capace di coordinare i propri giunti e reagire ad ostacoli in tempo reale per riuscire a muoversi efficacemente in ambienti complessi o non strutturati. Inoltre, aumentare la semplicità e ridurre il numero di controllori necessari alla locomozione alleggerise una struttura di controllo che potrebbe richiedere complessità per ulteriori attività specifiche. L'obiettivo di questa tesi è ottenere un comportamento autonomo cedevole che si adatti alla conformazione dell'ambiente in cui il robot si sta spostando, accrescendo le capacità di locomozione del serpente robot. Sfruttando la cedevolezza intrinseca del serpente robot utilizzato in questo lavoro, il SEA Snake, e utilizzando un controllo che combina cedevolezza attiva ad una struttura di coordinazione che ammette una decentralizzazione variabile del robot, si dimostra come tre andature possano essere modificate per ottenere una locomozione efficiente in ambienti complessi non noti a priori o non modellabili.

Synergistic nisin-polymyxin combinations for the control of Pseudomonas biofilm formation

The emergence and dissemination of multi-drug resistant pathogens is a global concern. Moreover, even greater levels of resistance are conferred on bacteria when in the form of biofilms (i.e., complex, sessile communities of bacteria embedded in an organic polymer matrix). For decades, antimicrobial peptides have been hailed as a potential solution to the paucity of novel antibiotics, either as natural inhibitors that can be used alone or in formulations with synergistically acting antibiotics. Here, we evaluate the potential of the antimicrobial peptide nisin to increase the efficacy of the antibiotics polymyxin and colistin, with a particular focus on their application to prevent biofilm formation of Pseudomonas aeruginosa. The results reveal that the concentrations of polymyxins that are required to effectively inhibit biofilm formation can be dramatically reduced when combined with nisin, thereby enhancing efficacy, and ultimately, restoring sensitivity. Such combination therapy may yield added benefits by virtue of reducing polymyxin toxicity through the administration of significantly lower levels of polymyxin antibiotics.
