Positive psychologists often see their work as fostering an emotional learning process that will prompt people to live a better, happier life. Positive psychology is supposed to feel gratifying, motivating, and inspiring. This paper will investigate two ethnographic situations where similar processes of gratification and transformation are in evidence, but without the presence of a formal psychological intervention. By comparing religious possession in an Afro-Brazilian cult and encounters with dolphins at sea, we suggest that both phenomena are “revelation-like” encounters built through the same kind of “enchanting device” (dispositifs d’enchantement). Drawing on first hand ethnographic accounts, we compare both settings in an attempt to identify common features in people’s experience, but also in how such experience is organized through imaginative and bodily commitment in “enchanting devices”. By “enchanting device”, we mean social and material environments that support spiritual encounters with real or imagined intentional entities. A deep involvement, a very focused attention (absorption), uncanny perceptions and emotions and trance-like states are found in each case. Phantasmagorical and/or religious imagination would play a central role in connecting such uncanny body states and perceptions with a set of cultural expectations and beliefs. In order to sustain this theoretical framework, our analysis will focus on a pragmatic analysis of the environmental features leading to an experience of enchantment. Our account of enchantment aims to broaden our understanding of psychologies of the positive and promises to enrich our understanding of well-being in relation to (deemed) religious and/or spiritual practices and experiences.  [less ▲]

This paper suggests that new decentralized and de-concentration reforms, which set out a framework to bring important governance functions to the sub-national level, have opened new spaces to explore complementary approaches for environmental governance. Using the Battambang spatial planning framework as a basis, the paper reviews some of the limitation of CBNRM implementation of the last ten years and then focuses on detailing the methodology used to develop and build the framework and how it can be beneficial to current CBNRM. The argument continually defended is that the integration of CBNRM initiatives into a comprehensive spatial planning framework at the provincial level can reinforce local actions and give communities stronger recognition. In a discussion of the three dimensions of the spatial planning framework which include land use planning, territorial policy, and territorial governance, the analysis does not negate the important contribution of local support to rural communities but tries to identify complementary (and not substitutive) approaches that might strengthen communities in their daily livelihood issues.

This paper deals with Caryl Phillips, whose fiction gives a voice to those who were silenced by history: lonely, marginalized characters such as Caribbean female migrants or Christianized slaves trying to convert their own people. Tales of family disruption, displacement, dis-membering, dispossession, loss are at the heart of his work. No wonder therefore if many of his characters, regardless of their gender, location or the time that they live in, enter the “realm of madness” as an ultimate exit from the unbearable pain of their lives. My proposal is to concentrate on Leila from The Final Passage (1985), Irina from Higher Ground (1989), Emily from Cambridge (1991) and Martha from Crossing the River (1993). These characters are motherless, husbandless and except for Leila, childless. Their traumatizing experiences, including a miscarriage, the birth of a stillborn baby, separation because of slavery, lead these four women to lose touch with reality, the pain driving them literally “crazy”. However, except for Martha, their “insanity”, momentary or definitive, opens the way to the logos which is uttered even if it disrupts the normative, patriarchal/colonialist society. Society’s silencing of these characters goes together with its inclination to associate mental disturbance with the realm of sound: hearing voices, shouting, screaming, repeated utterance. This sonic tendency is mirrored in Phillips’s writing. During the characters’ hallucinations, some passages create an aural experience alluding to their trauma, as some structural units are repeated over and over again. My contention is that these narrative devices transfer the characters’ chaotic experience into the writing and create a sense of confusion in the reader which privileges immediate empathy. [less ▲]

Noble metal nanoparticles (NPs) are intensively studied due to their particular optical properties, mainly high optical absorption and diffusion yields, leading to interesting applications in biochemical sensing, molecular tracking and imaging, drug delivery and photothermal therapies [1]. These unique optical properties arise from a physical process named surface plasmon resonance (SPR) which is a resonant coupling of incident light to the collective motion of electrons along the nanoparticles surface [2]. Optical SPR biosensors are able to measure complex formation in real time. Indeed, the SPR absorption spectrum band of the NPs is sensitive to the shape, size, inter-particle distance and composition of the NP as well as the dielectric properties of the surrounding medium [2]. Due to the sensitivity of SPR to the local dielectric environment, plasmonic NPs can thus act as transducers that convert small changes in the local refractive index or in the inter-particle distance into spectral shifts and broadenings of the absorption spectral bands [3]. Among metals, silver and gold NPs have received considerable interest for many reasons. For instance, they are stable in ambient atmosphere and exhibit good biocompatibility even if particular surface treatments are sometimes required. The Ag and Au NPs are also relatively easy to fabricate with different sizes and shapes allowing the tuning of the SPR optical absorption band from the near ultraviolet (400 nm) to the near infrared (1000 nm) wavelengths. In this study, our aim is to characterize two biosensors based on silver and gold spherical NPs in order to detect which one seems the best. Both NPs have a diameter close to 15 nm. We use the well-known biocytin-avidin complex as a model system because the bonding of avidin with biocytin is extremely strong with a dissociation constant three order of magnitude higher than the typical constants of antigen-antibody interactions. More precisely, we compare the intensities, the band shapes and the spectral locations of the SPR adsorption bands before and after the biomolecular recognition of avidin by biocytin molecules adsorbed on the Ag and Au NPs. The kinetic of the interaction is also discussed. Before surface treatment with biocytin, the NPs SPR bands are located around 390 and 520 nm for Ag and Au NPs, respectively. The SPR band intensity is higher for silver than for gold. Biocytin adsorption does not significantly modify the SPR spectral features. NPs do not therefore form aggregates and the local refraction index has not significantly changed. After avidin addition, a SPR red-shift and a broadening of the SPR bands are observed with both NPs as shown on Figure 1. These parameters evolved with time and reach their final values after around 45 min for each system. The aforementioned spectral changes arise from the biomolecular recognition process between biotin and avidin which leads to the NPs aggregation. The recognition process also induces a variation of the local refractive index around these NPs which contributes to the red-shift. The maximum SPR shifts are equal to 25 nm and 12 nm for silver NPs and gold NPs, respectively. Our results highlight the smaller dielectric sensitivity of gold NPs compared to the silver NPs one for a same particles’ size and for an equivalent concentration of avidin. The detection limit, described as the lowest concentration for clear identification of wavelength shift due to biomolecular recognition, is equal to 4 nM for both silver and gold NPs. With this protein concentration, 3 nm is the typical wavelength shift. The specificity of the biocytin - avidin biosensors is verified by replacing avidin by Bovine Serum Albumina (BSA). When BSA is added, we observe a SPR band shift which is smaller than the detection limit of 3 nm attesting the biosensor selectivity. Our work demonstrates the superiority of Ag over Au NPs for the elaboration of biosensors based on SPR. However, it is well-known that Ag NPs are less biocompatible than gold. This problem can be circumvented by an appropriate coating of the NPs surface prior ligand adsorption. [less ▲]

Poly(ethylene glycol)-b-poly(N-vinylcaprolactam) (PEG-b-PNVCL) copolymers are prepared from a PEG macro-chain transfer agent in DMF at 65 °C via reversible addition-fragmentation chain transfer (RAFT) polymerization. The well-defined PEG114-b-PNVCL237 copolymer with a cloud point temperature of 39 °C is used for the formation of a thermo-responsive polymer corona on the surface of gold nanorods (GNRs) via a “grafting-to” approach. Thermo-responsiveness and thermo-dependent optical properties of the as-obtained GNR@PEG-b-PNVCL nanoparticles are studied with dynamic light scattering and UV/vis spectroscopy techniques. Near infrared (NIR)-induced heating of GNR@PEG-b-PNVCL is also explored in aqueous suspension under NIR laser irradiation (802 nm, up to 250 mW). The potential of these GNR@PEG-b-PNVCL nanoparticles to be used as smart drug delivery systems (DDS) is then studied. A hydrophilic drug model, Rhodamine ® B, is used to assess the guest loading capacity, and triggered release behaviours are then evaluated under conventional external heating or internal heating induced by remote NIR irradiation. Cytotoxicity evaluation of the GNR@PEG-b-PNVCL against the fibroblast-like L929 cell line is carried out via the MTS assay in order to confirm the improved biocompatibility of the GNRs after polymer coating. These thermo-responsive GNR@PEG-b-PNVCL nanoparticles are promising DDS that combine the chemotherapeutic and phototherapeutic functions. [less ▲]

In this study, we report the synthesis of a nanoscaled drug delivery system, which is composed of a gold nanorod-like core and a mesoporous silica shell (GNR@MSNP) and partially uploaded with phase-changing molecules (1-tetradecanol, TD, Tm 39 degrees C) as gatekeepers, as well as its ability to regulate the release of doxorubicin (DOX). Indeed, a nearly zero premature release is evidenced at physiological temperature (37 degrees C), whereas the DOX release is efficiently achieved at higher temperature not only upon external heating, but also via internal heating generated by the GNR core under near infrared irradiation. When tagged with folate moieties, GNR@MSNPs target specifically to KB cells, which are known to overexpress the folate receptors. Such a precise control over drug release, combining with the photothermal effect of GNR cores, provides promising opportunity for localized synergistic photothermal ablation and chemotherapy. Moreover, the performance in killing the targeted cancer cells is more efficient compared with the single phototherapeutic modality of GNR@MSNPs. This versatile combination of local heating, phototherapeutics, chemotherapeutics and gating components opens up the possibilities for designing multifunctional drug delivery systems. [less ▲]

Herein, we report a new drug-delivery system (DDS) that is comprised of a near-infrared (NIR)- light-sensitive gold-nanorod (GNR) core and a phase-changing poly(e-caprolactone)- b-poly(ethylene glycol) polymer corona (GNR@PCL-b-PEG). The underlying mechanism of the drugloading and triggered-release behaviors involves the entrapment of drug payloads among the PCL crystallites and a heat-induced phase change, respectively. A low premature release of the pre-loaded doxorubicin was observed in PBS buffer (pH 7.4) at 37 °C (<10% of the entire payload after 48 h). However, release could be activated within 30 min by conventional heating at 50 °C, above the Tm of the crystalline PCL domain (43.5 °C), with about 60% release over the subsequent 42 h at 37 °C. The NIR-induced heating of an aqueous suspension of GNR@PCL-b- PEG under NIR irradiation (802 nm) was investigated in terms of the irradiation period, power, and concentrationdependent heating behavior, as well as the NIR-induced shape-transformation of the GNR cores. Remotely NIR-triggered release was also explored upon NIR irradiation for 30 min and about 70% release was achieved in the following 42 h at 37°C, with a mild warming (<4 °C) of the surroundings. The cytotoxicity of GNR@PCL-b-PEG against the mouse fibroblastic-like L929 cell-line was assessed by MTS assay and good compatibility was confirmed with a cell viability of over 90% after incubation for 72 h. The cellular uptake of GNR@PCL-b-PEG by melanoma MEL-5 cells was also confirmed, with an averaged uptake of 1250 ( ± 110) particles cell-1 after incubation for 12 h (50 mg mL-1). This GNR@PCL-b-PEG DDS is aimed at addressing the different requirements for therapeutic treatments and is envisaged to provide new insights into DDS targeting for remotely triggered release by NIR activation.

The new 2-phenylthiocarbamoyl-1,3-dimesitylimidazolium inner salt (IMes•CSNPh) reacts with [AuCl(L)] in the presence of NH4PF6 to yield [(L)Au(SCNPh•IMes)]+ (L = PMe3, PPh3, PCy3, CNBut).

Treatment of the diphosphine complex [(dppm)(AuCl)2] with one equivalent of IMes•CSNPh yields the digold metallacycle, [(dppm)Au 2(SCNPh•IMes)]2+, while reaction of [L 2(AuCl)2] with two equivalents of IMes•CSNPh results in [(L2){Au(SCNPh•IMes)}2]2+ (L2 = dppb, dppf, or dppa; dppb = 1,4-bis(diphenylphosphino)butane, dppf = 1,1'-bis(diphenylphosphino)ferrocene, dppa = 1,4- bis(diphenylphosphino)acetylene). The homoleptic complex [Au(SCNPh•IMes) 2]+ is formed on reaction of [AuCl(tht)] (tht = tetrahydrothiophene) with two equivalents of the imidazolium-2- phenylthiocarbamoyl ligand. This product reacts with AgOTf to yield the mixed metal compound [AuAg(SCNPh•IMes)2]2+. Over time, the unusual trimetallic complex [Au(AgOTf)2(SCNPh•IMes) 2]+ is formed. The sulfur-oxygen mixed-donor ligands IMes•COS and SIMes•COS (SIMes = 1,3-bis(2,4,6-trimethylphenyl) imidazolin-2-ylidene) were used to prepare [(L)Au(SOC•IMes)]+ and [(L)Au(SOC•SIMes)]+ from [(L)AuCl] (L = PPh3, CNtBu). The bimetallic examples [(dppf){Au(SOC•IMes)} 2]2+ and [(dppf){Au(SOC•SIMes)}2] 2+ were synthesized from the reaction of [(dppf)(AuCl)2] with the appropriate ligand. Reaction of [(tht)AuCl] with one equivalent of IMes•COS or SIMes•COS yields [Au(SOC•IMes) 2]+ and [Au(SOC•SIMes)2]+, respectively.

Au hydrogen bond. The latter resembles, by all features, a conventional hydrogen bond and is formed between a typical conventional proton donor N-H group and the gold cluster that behaves as a nonconventional proton acceptor. We provide strong computational evidence that the gold-ammonia bonding patterns exhibit distinct characteristics as the Z charge state of the gold cluster varies within Z=0,+/-1. The analysis of these bonding patterns and their effects on the N-H ... N H-bonded ammonia clusters are the subject of this paper. [less ▲]

After deposition of the so-loaded micelles onto a silicon wafer, followed by an appropriate thermal treatment, the poly(acrylonitrile) core of the micelles is carbonized, while the poly(vinyl alcohol) shell is completely decomposed and volatilized, leading to gold encapsulated in carbon nanoparticles. The morphology of the micelles is maintained during thermal treatment without requiring shell-cross-linking of the micelles prior to pyrolysis. [less ▲]
