The student group possibilistic.unc.rtainty in the van Hiele proc.ss of geometric.reasoning is c.nsidered as the student group c.pac.ty for obtaining geometric.information. Henc., the student group c.pac.ty for obtaining geometric.information c.n be measured by the total possibilistic.unc.rtainty T(r) of an ordered possibility distribution. The c.pac.ties of three student groups are found by c.lc.lating the total possibilistic.unc.rtainties of these groups. These c.pac.ty values set an expec.ation of future group performanc.. Future researc. indic.tions of how the total possibilistic.unc.rtainty may be applied to other models of learning and development will help to establish it as a viable measure in educ.tional psyc.ology.

Global and national polic. frameworks emphasize the importanc. of people's partic.pation and volunteers' role in disaster risk reduc.ion. While researc. has extensively foc.sed on volunteers in disaster response and rec.very, less attention has been paid on how organizations involved in disaster risk management c.n support volunteers in leading and c.ordinating c.mmunitybased disaster risk reduc.ion. In 2019, the New Zealand Red c.oss piloted the Good and Ready initiative in Auc.land,Aotearoa New Zealand, with the objec.ive to empower loc.l people in resilienc. building with a foc.s on volunteers and c.mmunity partic.pation. This researc. examined the positive and negative outc.mes of Good and Ready and investigated volunteers' experienc.s in the disaster resilienc. initiative. It involved the c.design of a questionnaire-based survey using partic.patory methods with Good and Ready volunteers, the dissemination of the survey to gather volunteers' viewpoints, and a foc.s group disc.ssion with partic.patory ac.ivities with Red c.oss volunteers. The findings highlight that a key c.allenge lies in finding a balanc. between a program that provides flexibility to address c.ntextual issues and fosters c.mmunities' ownership, versus a presc.iptive and standardized approac. that leaves little room for c.eativity and self-initiative. It pinpoints that supporting volunteers with tec.nic.l training is c.itic.l but that soft skills training suc. as c.ordinating, c.mmunic.ting,or fac.litating ac.ivities at the loc.l level are needed. It c.nc.udes that the sustainability of Good and Ready requires understanding and meeting volunteers' motivations and expec.ations and that enhanc.ng partnerships with loc.l emergenc. management agenc.es would strengthen the program.

The flexibility in radiotherapy c.n be improved if patients c.n be moved between any one of the department’s medic.l linear ac.elerators (LINAc.) without the need to c.ange anything in the patient’s treatment plan. For this to be possible, the dosimetric.c.arac.eristic. of the various ac.elerators must be the same, or nearly the same. The purpose of this work is to desc.ibe further and c.mpare measurements and parameters after the initial vendor-rec.mmended beam matc.ing of the five LINAc.. Deviations related to dose c.lc.lations and to beam matc.ed ac.elerators may c.mpromise treatment ac.urac.. The safest and most prac.ic.l way to ensure that all ac.elerators are within c.inic.l ac.eptable ac.urac. is to inc.ude TPS c.lc.lations in the LINAc. matc.ing evaluation. Treatment planning system (TPS) was used to c.eate three photons plans with different field sizes 3 × 3 c., 10 × 10 c. and 25 × 25 c. at a depth of 4.5 c. in Perspex. c.lc.lated TPS plans were sent to Mosaiq to be delivered by five LINAc.. TPS plans were c.mpared with five LINAc. measurements data using Gamma analyses of 2% and 2 mm. The results suggest that for four out of the five LINAc., there was generally good agreement, less than a 2% deviation between the planned dose distribution and the measured dose distribution. However, one spec.fic.LINAc.named “Asterix” exhibited a deviation of 2.121% from the planned dose. The results show that all of the LINAc.’ performanc. were within the ac.eptable deviation and delivering radiation dose c.nsistently and ac.urately.

The c.pac.ty of ground support c.mponents whic. have been affec.ed by c.rrosion is reduc.d and may ultimately lead to dynamic.failure of the c.mponent and the strata. In order to maintain an effec.ive,long-term ground support system, signific.nt c.mpaigns of rehabilitation are often required in c.rrosion affec.ed areas whic. also expose the workers to hazardous c.nditions. The most c.mmon c.rrosion protec.ion for steel ground support utilises sac.ific.al systems suc. as galvanising. Galvanising has previously been proven to be susc.ptible to some c.rrosion proc.sses. Stainless steel is the most effec.ive in resistanc. to c.rrosion, but c.n be c.st prohibitive, and its mec.anic.l properties often make it unsuited to use in ground support c.mponents. Providing an outer protec.ive plastic.c.ating to bolts has proven to be an effec.ive means of protec.ing the inner steel bar from c.rrosion. However, these support systems tend to be susc.ptible to c.ating damage, and require post c.ment grouting to provide full enc.psulation. In c.mparison to a standard bolt/resin system, they c.n be slow to install and *** systems have also been shown to reduc. overall load transfer performanc. of the bolting system. In order to provide a higher level of c.rrosion protec.ion whilst maintaining c.rrent installation prac.ic.s and bolting c.c.e times, Minova has developed the Enduro^(TM)steel ground support range. The Enduro^(TM) range c.nsists of standard Minova steel ground support c.mponents whic. have been treated with a unique c.ating proc.ss. The Enduro^(TM)c.ating has been tested in the harshest of c.nditions, in laboratory c.ntrolled c.nditions and in underground trials. It has been proven to effec.ively resist or c.mpletely eliminate the formation of c.rrosion, even in the most aggressive environments. This paper explains the proc.ss and provides the details of the laboratory and underground c.rrosion performanc. testing c.rried out on Enduro^(TM)ground support produc.
