Enhanced light extraction from emitters close to clusters of resonant plasmonic nanoantennas
Get PDFWe perform time-resolved fluorescence spectroscopy on clusters of plasmonic nanoantennas covered with a dye–polymer mixture. Dimer antenna structures were fabricated consisting of two interacting gold nanorods with varying lengths and interparticle separation. By combining four individual antennas into a cluster within a diffraction limited spot size, we can couple out half of the dye molecule fluorescence via antenna plasmons. Two-dimensional confocal fluorescence lifetime scans visualize the spontaneous emission enhancement of the molecular fluorescence around the antenna clusters

RiVAS and RiVAS+: Opportunities for Application of a Multi-Criteria River Value Assessment System Approach which Considers Existing and Potential States
Get PDFThe River Values Assessment System (RiVAS) uses a combination of expert panels and multi criteria analysis to identify primary attributes (or main features) of river values (e.g., whitewater kayaking, native birds) and their key indicators. The resulting data set is used to rank rivers for their existing (instream) and potential (out-of-stream) significance. The RiVAS method has been applied to seven values and tested across a range of councils with most focus in Tasman District. The tool has demonstrated utility and is very cost effective to implement. Further development has now led to RiVAS+ to consider potential significance for instream values, using the same attributes and indicators, and also identifying the interventions needed to achieve these potential future states (e.g., water quality improvements, willow removal, increased flows). RiVAS+ enables instream uses to be considered on the same basis as out-of-stream opportunities. RiVAS+ can be undertaken more-or-less concurrently with RiVAS and enables a range of applications. First, it allows decision makers to gain an understanding of the difference between existing relative importance or significance of a value and its potential (if restored or developed). Second, it enables better evaluation of potential restoration or development options in a range of circumstances including where water resource development is planned. Finally, with further input it might be possible to quantify the cost of the interventions which would then allow better consideration of mitigation and other options in resource management policy and decision making processes. In this paper we demonstrate the method and the opportunities.River values, prioritisation system, existing and potential, interventions, New Zealand, Environmental Economics and Policy,
Cooperation with parents and coworkers as a possible origin of stress in preschool educators
Get PDFDiplomsko delo z naslovom Sodelovanje s starši in sodelavci kot možen izvor stresa pri vzgojiteljih predšolskih otrok je sestavljeno iz teoretičnega in empiričnega dela. V teoretičnem delu smo govorili o sodelovanju, ki poteka v vrtcu, torej o sodelovanju s starši, sodelavci, vodstvom in ostalimi strokovnjaki. Sodelovanje oziroma vrste sodelovanj smo bolj specifično opredelili. Potem smo nekaj besed namenili raziskavam, kako sodelovanje vpliva na stres vzgojitelja. Opredelili smo stres, vrste stresa, stresorje in kako prepoznamo stres v našem življenju. Posvetili smo se tudi sprostitvenim tehnikam, za katere smo mnenja, da so v našem življenju pomembne. Izmed vseh sprostitvenih tehnik, ki obstajajo, smo jih bolj podrobno opredelili pet. V empiričnem delu smo raziskali pojav stresa pri vzgojiteljih v vrtcih. Zanimalo nas je, ali vzgojitelji doživljajo stres, katero vrsto stresa pri sebi opazijo (pozitivnega ali negativnega), katere stresorje bi lahko pripisali sami sebi, kako na stres vplivajo vrste sodelovanja s starši, kako se počutijo pred timskimi sestanki in v vrtcu v sodelovanju s sodelavci, vodstvom in svetovalnimi delavci oziroma ostalimi strokovnjaki. Na koncu pa nas je zanimalo, ali se sproščajo in kako.Thesis Cooperation with parents and coworkers as a possible origin of stress in preschool educators consists of theoretical and empirical part. The first part discusses cooperation inside kindergarten: cooperation with parents, coworkers, kindergarten management and other associate professionals. Cooperation and types of cooperation are dealt with in detail. We also research and discuss cooperation as a cause of stress in preschool educator. We define stress, types of stress, stressors and recognizing stress every day. Relaxation techniques that play an important role in our lives are dealt with. Among all existing relaxation techniques five are chosen and defined. The second part presents a research on stress in kindergarten educators. The focus is on experience of stress, which type is recognised (positive or negative one), which stressors come from themselves, how different kinds of cooperation with parents can influence stress, how they feel before team meetings, before cooperation with coworkers, kindergarten management and other associate professionals. In the end we focus on whether they use any relaxation techniques and how

Most of the morphological structures of the new Mexican species are similar to this South American species. These features include the ocular plates, as well as the ornamentation on plates and leg telofemur. Notable differences include the setae which lie outside the ocular plate in <i>S. cramerae</i>, and on it in <i>S. similis</i>. Likewise, ds­3 is located on the AD plate in <i>S. cramerae,</i> and outside of this plate in <i>S. similis</i>. P2 of the new species has a ventral bristle similar to that of <i>S. similis</i> and <i>S. areolatus</i> from Chile, but without being borne on a knob (the ventral apophysis). The setal pattern of the Mexican species is shared with <i>S. areolatus</i>, but the ornamentation of the latter is quite distinctive, differing from that of <i>S. cramerae</i> with the P2.</p> <p> Newell (1984) designated six species (<i>S. obtusus, S. subobtusus, S. areolatus, S. magellanicus, S. hulingsi</i>, and <i>S. pectinatus</i>) from South America as “group 1” based on a shared suite of features. The Mexican species described here shares several of these characters, specially with <i>S. hulingsi</i>, in which only the location of ds­2, the number of the minute teeth on claw processes, the size of the idiosoma, and the form of the anterior margin of PD are different. The ornamentation with foveae on the telofemur of <i>S. cramerae</i> is very similar to that of <i>S. coreensis</i> Chatterjee & Young Chang, 2004 from Korea. However, the two species differ in the position of ds­2, the width of AD and PD, and the number of minute teeth on the claw processes.</p> <p> Also <i>S. cramerae</i> <b>sp. nov.</b> is closely with <i>S. fuscus</i> Viets and <i>S. euphractus</i> Pepato & Gonçalvez­Tiago, both cited from American Atlantic. These three species have the ds­2 outside of OC and similar ornamentation of dorsal plates, however <i>S. fuscus</i> and <i>S. euphractus</i> have a knob (ventral apophysis) on P2, which <i>S. cramerae</i> does not have. <i>S. euphractus</i> has two ventral setae on tarsus IV and <i>S. cramerae</i> only has one; <i>S. fuscus</i> has OC rounded in the terminal portion and in <i>S. cramerae</i> it is pointed, the tibia and tarsus are narrower in <i>S</i>. <i>fuscus</i> than in <i>S. cramerae</i>, and the number of minute teeth of claws in <i>S cramerae</i> (6–8) is smaller than in <i>S. fuscus</i> (10–14).</p>Published as part of <i>Rivas, Gerardo, 2006, First record of Simognathus (Acari: Halacaridae) from Mexico, including the description of a new species, pp. 61-68 in Zootaxa 1259</i> on pages 62-66, DOI: <a href="http://zenodo.org/record/173153">10.5281/zenodo.173153</a>

Jet boating on Canterbury rivers: Application of the river values assessment system (RiVAS)
No full textThe River Values Assessment System methodology was used to determine the relative importance of different rivers and sections of rivers to jetboating in Canterbury. Primary attributes of jetboating and associated indicators was used as the basis for applying the RiVAS methodology. In total 40 sections or whole river systems were assessed. Ten were considered of national significance for jetboating with the highest ranked being the Poulter to Woodstock section of the Waimakariri and the Wilberforce to Gorge Bridge section of the Rakaia
