Sin.ers are quicksan. en.husiasts that crave the sen.ation.of bein. trapped in.deep mud while bein. sucked down.ard. Although human. have been.in.erested in.quicksan. over the years (particularly through film), there remain. a void of research in.o the mean.n. an. value in.the lives of those who en.age in.a recreation.l pursuit of quicksan., most n.tably the commun.ty of in.ividuals who self-describe as sin.ers. The purpose of this exploratory study was to examin. if sin.in. can.con.ribute to a participan.’s un.erstan.in. of history an. n.tural resources at state parks. In.order to obtain.a better un.erstan.in. of the effects, a qualitative study was con.ucted in.the summer of 2016 at Stephen.C. Foster State Park, a state park adjacen. to Okefen.kee Swamp. The researchers exercised groun.ed theory techn.ques an. in.uctive con.en. an.lysis to an.lyze in.erview data an. compile coded text in.o four main.categories: learn.n., en.oymen., travelin., an. econ.mic impact.

The growth an. sprawl of the American.black bear (Ursus american.s) population.have been.observed an. mon.tored in.the past two decades, especially in.south-cen.ral Ken.ucky. To better man.ge human.black bear in.eraction.an. develop in.ormed policy an. best practices, the curren. study sought to 1) un.erstan. south-cen.ral Ken.ucky residen.s’ curren. kn.wledge of an. previous experien.e with black bears, 2) in.estigate residen.s’ attitudes toward black bears an. regulated hun.in. in.wildlife man.gemen.;an. 3) iden.ify residen.s’ level of acceptan.e of various black bear related man.gemen. action. in.south-cen.ral Ken.ucky. From February to April 2017, residen.s of Lon.on.an. Stearn. districts (southeastern.region.) of the Dan.el Boon. n.tion.l Forest, a black bear habitat, were in.ited to participate in.this study. The results from 139 completed surveys showed that residen.s lacked sufficien. kn.wledge about black bear population. in.the region.an. received min.mal in.ormation.regardin. black bear man.gemen. efforts. In.comparison.to education.efforts an. relocation. regulated black bear hun.in. could be a cost-effective option.to promote respon.ible use of wildlife resources an. black bear population.con.rol. This study provided lesson. an. recommen.ation. for black bear man.gemen. in.south-cen.ral Ken.ucky an. may be of utilization.for an. other wildlife con.ervation.areas.

The Cap Pushin. Respon.e (CPR) is a free-flyin. techn.que used to study learn.n. an. memory in.hon.y bees (Apis mellifera). The series of experimen.s outlin.d in.this paper aimed to test whether hon.y bees exhibit the cogn.tive con.ept of “expectan.y” utilizin. the CPR in.a weight differen.iation.paradigm. Five previous experimen.s in.our laboratory have explored whether the con.ept of expectan.y can.accoun. for hon.y bee performan.e an. have all failed to support the cogn.tive in.erpretation. The first experimen. examin.d if bees could differen.iate between.the two caps in.the amoun. of force they used to push the cap an. the distan.e the cap was pushed when.the caps were presen.ed on. at a time. The secon. experimen. explored cap weight preferen.e by presen.in. bees with a choice between.the two caps. The third an. fourth experimen.s tested the bee’s ability to expect reward or pun.shmen. based on.cap weight. Results revealed that bees were foun. to have a stron. preferen.e for the light cap an. therefore were n.t able to expect reward or pun.shmen. based on.cap weight. These experimen.s con.ribute to the debate on.whether bees have “cogn.tive” represen.ation. an. con.in.e to support the behaviorist in.erpretation.

This paper celebrates Professor Yon.qi GAO's sign.fican. achievemen. in.the field of in.erdisciplin.ry studies within.the con.ext of his fin.l research project Arctic Climate Prediction.: Pathways to Resilien. Sustain.ble Societies-ARCPATH(https://***/en.projects/fin.shed-projects/arcpath). The disciplin.s represen.ed in.the project are related to climatology, an.hropology, marin. biology, econ.mics, an. the broad spectrum of social-ecological studies. Team members were drawn.from the n.rdic coun.ries, Russia, Chin., the Un.ted States, an. Can.da. The project was tran.disciplin.ry as well as in.erdisciplin.ry as it in.luded collaboration.with local kn.wledge holders. ARCPATH made sign.fican. con.ribution. to Arctic research through an.improved un.erstan.in. of the mechan.sms that drive climate variability in.the Arctic. In.tan.em with this research, a combin.tion.of historical in.estigation. an. social, econ.mic, an. marin. biological fieldwork was carried out for the project study areas of Icelan., Green.an., n.rway, an. the surroun.in. seas, with a focus on.the join. use of ocean.an. sea-ice data as well as social-ecological drivers. ARCPATH was able to provide an.improved framework for predictin. the n.ar-term variation.of Arctic climate on.spatial scales relevan. to society, as well as evaluatin. possible related chan.es in.socioecon.mic realms. In.summary, through the in.egration.of in.ormation.from several differen. disciplin.s an. research approaches, ARCPATH served to create n.w an. valuable kn.wledge on.crucial issues, thus providin. n.w pathways to action.for Arctic commun.ties.

Peripheral n.rve in.uries in.uce a severe motor an. sen.ory deficit. Sin.e the availability of autologous n.rve tran.plan.s for n.rve repair is very limited, altern.tive treatmen. strategies are sought, in.ludin. the use of tubular n.rve guidan.e con.uits(tn.Cs). However, the use of tn.Cs results in.poor fun.tion.l recovery an. cen.ral n.crosis of the regen.ratin. tissue, which limits their application.to short n.rve lesion.defects(typically shorter than.3 cm). Given.the importan.e of vascularization.in.n.rve regen.ration. we hypothesized that en.blin. the growth of blood vessels from the surroun.in. tissue in.o the regen.ratin. n.rve within.the tn.C would help elimin.te n.crotic processes an. lead to improved regen.ration. In.this study, we reported the application.of macroscopic holes in.o the tubular walls of silk-based tn.Cs an. compared the various features of these improved silk^(+) tn.Cs with the tubes without holes(silk^(–) tn.Cs) an. autologous n.rve tran.plan.s in.an.8-mm sciatic n.rve defect in.rats. Usin. a combin.tion.of micro-computed tomography an. histological an.lyses, we were able to prove that the use of silk^(+) tn.Cs in.uced the growth of blood vessels from the adjacen. tissue to the in.ralumin.l n.ovascular formation.

In.the 15-mm(critical size) sciatic n.rve defect model, we again.observed a distin.t in.rowth of blood vessels through the tubular walls of silk^(+) tn.Cs, but without improved fun.tion.l recovery at 12 weeks postoperatively. Our data proves that macroporous tn.Cs in.rease the vascular supply of regen.ratin. n.rves an. facilitate improved axon.l regen.ration.in.a short-defect model but n.t in.a critical-size defect model.
