Psychological biases of individual investors and financial satisfaction
Authors: Sahi Shalini Kalra 
Published: April 2017

AbstractTraditional finance theory is based on the principle of maximization of utility and explains how choices are made by rational people. Although the theory provides numerous insights, observation of actual behavior of people was seen to be different from what the theory predicted. The homo economicus is in reality a homo sapien who has emotions and beliefs that help to filter the content from his or her environment. These beliefs and preferences that arise due to cognitive limitations, presence of emotions, and various psychological motives guide or bias his or her decisions. Much literature states that the biases should be corrected as they negatively impact financial behaviour and individual's well‐being. However, evolutionary psychology considers biases as design features of human mind. Thus, biases are not always bad, as at times, these biases can help the individual investor to choose the best course of action from the multiple possibilities and enable committing the less costly mistakes, thereby helping the individual to achieve satisficing behaviour. This paper aims to explore the investor biases and see whether they are related to the financial satisfaction of the individuals. Financial satisfaction is the measure of satisfaction with one's financial situation. The results showed that overconfidence bias, reliance on expert bias, and self‐control bias have a positive and significant association with financial satisfaction levels. Association of a few other biases with financial satisfaction was also observed under certain control conditions. This study provides further insights on investor behavior and paves the way for various possibilities for future research.
Chemical Activation in Blood Serum and Human Cell Culture: Improved Ruthenium Complex for Catalytic Uncaging of Alloc‐Protected Amines
Authors: Völker Timo , Meggers Eric 
Published: April 2017

AbstractChemical (as opposed to light‐induced) activation of caged molecules is a rapidly advancing approach to trigger biological processes. We previously introduced the ruthenium‐catalyzed release of allyloxycarbonyl (alloc)‐protected amines in human cells. A restriction of this and all other methods is the limited lifetime of the catalyst, thus hampering meaningful applications. In this study, we addressed this problem with the development of a new generation of ruthenium complexes for the uncaging of alloc‐protected amines with superior catalytic activity. Under biologically relevant conditions, we achieved a turnover number >300, a reaction rate of 580 m−1 s−1, and we observed high activity in blood serum. Furthermore, alloc‐protected doxorubicin, as an anticancer prodrug, could be activated in human cell culture and induced apoptosis with a single low dose (1 μm) of the new catalyst.

Published: April 2017

AbstractN,N′‐Disubstituted bipyridinium (viologen) and N‐monosubstituted bipyridinium compounds are well known for their electron‐transfer (ET) photochromic behavior. Their modification has exclusively focused on the N‐substituents to date. For the first time, we have studied the photochromic behavior when one pyridyl ring of the bipyridinium is substituted with a multifunctional azole group, and have found that two new coordination compounds based on N‐methyl‐4‐pyridinium tetrazolate (mptz) zwitterion, [Zn(mptz)2Br2] (1) and [Cd3(mptz)2Cl6]n⋅4n H2O (2), exhibit typical ET photochromic behavior owing to photoinduced ET from halogen anion to the mptz ligand. This work demonstrates a new simple, neutral photoactive molecule with electron‐accepting ability, which may act as a photoactive component for materials with potential photoswitching and photocatalysis applications.

Published: April 2017

AbstractSupramolecular hydrogels are composed of self‐assembled solid networks that restrict the flow of water. l‐Phenylalanine is the smallest molecule reported to date to form gel networks in water, and it is of particular interest due to its crystalline gel state. Single and multi‐component hydrogels of l‐phenylalanine are used herein as model materials to develop an NMR‐based analytical approach to gain insight into the mechanisms of supramolecular gelation. Structure and composition of the gel fibres were probed using PXRD, solid‐state NMR experiments and microscopic techniques. Solution‐state NMR studies probed the properties of free gelator molecules in an equilibrium with bound molecules. The dynamics of exchange at the gel/solution interfaces was investigated further using high‐resolution magic angle spinning (HR‐MAS) and saturation transfer difference (STD) NMR experiments. This approach allowed the identification of which additive molecules contributed in modifying the material properties.
Near‐Infrared Circularly Polarized Light Triggered Enantioselective Photopolymerization by Using Upconversion Nanophosphors

Published: April 2017

AbstractCircularly polarized light (CPL) is considered to be a true chiral entity and has been suggested as an explanation for the introduction of initial chiral biases into key biomolecular building blocks. CPL used recently asymmetric photochemical reactions is of wavelengths mainly in the UV and visible regions, whereas natural CPL observed in star‐forming regions of the Orion constellation falls in the IR region. Whether CPL in the IR or near‐IR region could be utilized to trigger asymmetric photochemical reactions remains to be determined. Herein, it is demonstrated that enantioselective photopolymerization can be realized by using λ=980 nm CPL as the only chiral source. By incorporating NaYF4 nanophosphors as the antenna species, the enantioselective photopolymerization of achiral benzaldehyde‐substituted diacetylene monomer can be realized based on an upconversion mechanism upon exposure to λ=980 nm CPL. The screw direction of the helical PDA chains can be completely controlled by the handedness of incident λ=980 nm CPL.

Published: April 2017

AbstractWe report the development of a two‐component probe system as fluorescence turn‐on assay of simple saccharides. The quenching of an anionic conjugated water‐soluble polymer by a cationic quencher has been reported previously. Three different boronic acid functionalized benzyl viologens and three conjugated polymers of the poly(aryleneethynylene) type form nine non‐fluorescent complexes. This small library discriminates nine different simple saccharides in aqueous solutions by fluorescence turn‐on in a displacement assay. The saccharides can be discriminated and identified with this simple system.

Published: April 2017

Abstract10,15,20‐Tris(pentafluorophenyl)‐substituted NiII–porphyrin meso‐oxy radical bearing two coordinating pyridines was synthesized as a stable radical with a quartet ground state (S=3/2). X‐ray structural analysis revealed that the NiII porphyrin moiety is fairly planar and the Ni−N bond lengths are considerably longer, indicating the high‐spin state of the NiII center. The radical exhibited a quartet ground state, indicating the ferromagnetic interaction between the high‐spin NiII center (S=1) and the porphyrin meso‐oxy radical (S=1/2).

Published: April 2017

AbstractThe synthesis of alternating donor–acceptor [12] and [16]cycloparaphenylenes (CPPs) has been achieved by the rhodium‐catalyzed intermolecular cross‐cyclotrimerization followed by imidation and/or aromatization. These alternating donor–acceptor CPPs showed positive solvatofluorochromic properties and smaller HOMO–LUMO gaps compared with nonfunctionalized CPPs, which was confirmed by the theoretical study.

Published: April 2017

AbstractBifunctional electrically conducting single‐molecule magnets are highly promising platforms for non‐volatile memory devices and quantum computing applications. The development of these molecular materials, however, has largely been hindered by the lack of straightforward synthetic methods. Herein a facile and modular approach is demonstrated for the realization of bifunctional materials that does not require electrochemical or chemical oxidation to obtain partially charged organic radicals. Magnetic and electrical conductivity studies reveal that the DyIII compound exhibits slow relaxation of the magnetization between 5.0–8.0 K and semiconducting behavior over the range 180–350 K. DC magnetic fields have been found to suppress the quantum tunneling of the magnetization and affect the spin‐canted antiferromagnetic interactions.
CDSpecTech: A single software suite for multiple chiroptical spectroscopic analyses
Authors: Covington Cody L. , Polavarapu Prasad L. 
Published: April 2017

AbstractThe program CDSpecTech was developed to facilitate the analysis of chiroptical spectra, which include the following: vibrational circular dichroism (VCD) and corresponding vibrational absorption (VA) spectra; vibrational Raman optical activity (VROA) and corresponding vibrational Raman spectra; electronic circular dichroism (ECD) and corresponding electronic absorption (EA) spectra. In addition, the program allows for generating optical rotatory dispersion (ORD) as the Kramers–Kronig transform of ECD spectra. The simulation of theoretical spectra from transition strengths can be achieved using different bandshape profiles. The experimental and simulated theoretical spectra can be visually compared by displaying them together. A unique feature of CDSpecTech is performing spectral analysis using the ratio spectra; i.e., the dimensionless dissymmetry factor (DF) spectrum, which is the ratio of CD to absorption spectra, and the dimensionless circular intensity difference (CID) spectrum, which is the ratio of VROA to vibrational Raman spectra. The quantitative agreement between experimental and simulated theoretical spectra can also be assessed from the numerical similarity overlap between them. Two different similarity overlap methods are available. The program uses a graphical user interface which allows for ease of use and facilitates the analysis. All these features make CDSpecTech a valuable tool for the analysis of chiroptical spectra. The program is freely available on the World Wide Web.

New colour appearance scales for describing saturation, vividness, blackness, and whiteness
Authors: Cho Yoon Ji , Ou Li‐Chen , Cui Guihua , Luo Ronnier 
Published: April 2017

AbstractThis article describes the development of new models for predicting four colour appearance attributes: saturation, vividness, blackness, and whiteness. The new models were developed on the basis of experimental data accumulated in the authors' previous study, in which the four colour appearance attributes were scaled by 64 Korean and 68 British observers using the categorical judgment method. Two types of models were developed: the ellipsoid‐based and the hue‐based. For the former, the perceived saturation, vividness, blackness, and whiteness were modeled in the form of colour‐difference formulae between the test colour and a reference colour. For the latter, blackness, whiteness, and chromaticness scales were modeled by estimating hue‐dependent lightness and chroma values for the “full colour” in the framework of Adams' equation. The new models were tested using NCS data and were found to outperform some of the existing colour appearance models.

Published: April 2017

AbstractVorapaxar is a first‐in‐class antagonist of the protease‐activated receptor‐1, the primary thrombin receptor on human platelets, which mediates the downstream effects of thrombin in hemostasis and thrombosis. Prasugrel is a platelet inhibitor that acts as a P2Y12 receptor antagonist through an active metabolite, R‐138727. This study investigated the interaction of these 2 platelet antagonists when coadministered. This was a randomized, open‐label, multiple‐dose study in 54 healthy volunteers consisting of a fixed‐sequence crossover and a parallel group design. In sequence 1, 36 subjects received prasugrel 60 mg on day 1 and then prasugrel 10 mg once daily on days 2 to 7, followed by vorapaxar 40 mg and prasugrel 10 mg on day 8 and then vorapaxar 2.5 mg and prasugrel 10 mg orally once daily on days 9 to 28. In sequence 2, 18 subjects received vorapaxar 40 mg on day 1 and then vorapaxar 2.5 mg once daily on days 2 to 21. The geometric mean ratios (90% confidence intervals) for AUCτ and Cmax of coadministration/monotherapy for vorapaxar (0.93 ng·h/mL[0.85–1.02 ng·h/mL] and 0.95 ng/mL [0.86–1.05 ng/mL]) and R‐138727 (0.91 ng·h/mL [0.85– 0.99 ng·h/mL] and 1.02 ng/mL [0.89–1.17 ng/mL]) were within prespecified bounds, demonstrating the absence of a pharmacokinetic interaction between vorapaxar and prasugrel. There was no specific safety or tolerability risk associated with multiple‐dose coadministration of vorapaxar and prasugrel. In conclusion, in this study in healthy volunteers, there was no pharmacokinetic drug–drug interaction between vorapaxar and prasugrel. Multiple‐dose coadministration of the 2 drugs was generally well tolerated.

Published: April 2017

AbstractCytokines are thought to play an important role in the pathogenesis of periodontal disease. Because periodontal disease is known for its inhomogeneous distribution within the dentition, it is unclear to what extent the detection of various cytokines at different sites correlates with presence of disease. We evaluated whether levels of 12 cytokines in gingival crevicular fluid (GCF) discriminated periodontally diseased sites from healthy ones, or periodontally diseased persons from healthy ones, and assessed the impact of nonsurgical periodontal therapy on these readings. This study included 20 periodontally healthy persons (H) and 24 patients with chronic periodontitis (P). In every participant, we measured the plaque index, gingival index, probing pocket depth (PD), bleeding on probing, and recession at six sites of every tooth. GCF was collected with Durapore® filter strips from two healthy sites (PD<4 mm; HH) in group H, and from two periodontally diseased sites (PD≥5 mm; PP) and two periodontally healthy sites (PD≤3 mm; PH) in group P. The periodontally diseased participants underwent comprehensive nonsurgical periodontal therapy including deep scaling and root planing under local anesthesia. In these participants, GCF samples were again collected at the same sites 1 and 3 months after therapy. Twelve cytokines (il‐1β, il‐1ra, il‐6, il‐8, il‐17, b‐fgf, g‐csf, gm‐csf, ifn‐γ, mip‐1β, vegf, and tnf‐α) were assessed using the Bio‐Plex suspension array system. Mean plaque index, gingival index, bleeding on probing, PD, and recession were significantly different between groups H and P. Differences between PP and PH sites were not significant for any of the cytokines. Il‐1ra, il‐6, il‐17, b‐fgf, gm‐csf, mip‐1β, and tnf‐α differed significantly between HH sites and both PH and PP sites, whereas il‐8 was significantly higher only at PP sites. Periodontal treatment increased gm‐csf and decreased il‐1ra levels in PP sites. Il‐1ra, il‐6, il‐8, il‐17, b‐fgf, gm‐csf, mip‐1β, and tnf‐α identified patients with chronic periodontitis, rather than diseased sites, suggesting a generalized inflammatory state that is not limited to clinically diseased sites only.

Published: April 2017

AbstractThe scientific community has been seeking cost‐competitive and green solvents with good dissolving capacity for the valorization of lignocellulosic biomass. At this point, deep eutectic solvents (DESs) are currently emerging as a new class of promising solvents that are generally liquid eutectic mixtures formed by self‐association (or hydrogen‐bonding interaction) of two or three components. DESs are attractive solvents for the fractionation (or pretreatment) of lignocellulose and the valorization of lignin, owing to the high solubility of lignin in DESs. DESs are also employed as effective media for the modification of cellulose to afford functionalized cellulosic materials, such as cellulose nanocrystals. More interestingly, biomassderived carbohydrates, such as fructose, can be used as one of the constituents of DESs and then dehydrated to 5‐hydroxymethylfurfural in high yield. In this review, a comprehensive summary of recent contribution of DESs to the processing of lignocellulosic biomass and its derivatives is provided. Moreover, further discussion about the challenges of the application of DESs in biomass processing is presented.

AbstractObjectiveEvaluate the association of military sexual trauma (MST) screen status with eating disorder diagnoses among veterans within 1‐ and 5‐years after initiating Veterans Health Administration (VHA) care, and whether the association varied by sex.MethodRetrospective cohort study of US Afghanistan/Iraq veterans who used VHA services between FY 2004 and 2014 (N = 595,525). This study used VHA administrative data to assess the presence of eating disorder diagnoses in medical records within 1‐ and 5‐years of initiating VHA care, and whether a positive screen for MST was associated with eating disorders.ResultsThree percent (n = 18,488) screened positive for MST. At 1‐ and 5‐year follow up, 0.1% (n= 513, 74% female), and 0.2% (n = 504, 71% female) were diagnosed with an eating disorder, respectively. In regression models adjusted for demographic variables, military service, and psychiatric comorbidities, the presence of an eating disorder diagnosis was nearly two times higher among those with a positive screen for MST in the 1‐year (adjusted odds ratio [AOR] = 1.94, 95% confidence interval [CI] = 1.57–2.40) and 5‐year (AOR = 1.86, 95%CI = 1.49–2.32) cohorts. The increased likelihood conferred by MST for an eating disorder diagnosis was differentially stronger among male veterans than female veterans in the 1‐year cohort only (AOR = 2.13, 95%CI = 1.01–4.50).DiscussionVeterans with a positive screen for MST, especially male veterans, had a nearly two‐fold increased likelihood of having an eating disorder diagnosis. Screening for eating disorders may be important in both male and female veterans who report MST.
Spider (Arachnida, Araneae) diversity in secondary and old‐growth southern Atlantic forests of Paraná state, Brazil

Published: April 2017

AbstractThe data presented here have been collected in the southern part of the Atlantic Forest (Mata Atlântica) in the state of Paraná, Brazil within a bilateral scientific project (SOLOBIOMA). The project aimed to assess the quality of secondary forests of different regeneration stages in comparison with old‐growth forests with regard to diversity of soil animals and related functions. The Atlantic Forest is a hotspot of biological diversity with an exceptionally high degree of endemic species, extending over a range of 3,500 km along the coast of Brazil. The anthropogenic pressure in the region is very high with three of the biggest cities of Brazil (São Paulo, Rio de Janeiro, and Curitiba) lying in its extension. An evaluation of the value of secondary forests for biodiversity conservation is becoming more and more important due to the complete disappearance of primary forests. In 2005, we sampled spiders in 12 sites of three successional stages (5–8, 10–15, 35–50 yr old, three replicates of each forest stage) and old‐growth forests (> 100 yr untouched, also three replicates). All sites were inside a private nature reserve (Rio Cachoeira Nature Reserve). We repeated the sampling design and procedure in 2007 in a second private reserve (Itaqui Nature Reserve). The two nature reserves are within about 25 km of each other within a well preserved region of the Mata Atlântica, where the matrix of the landscape mosaic is still forest. A widely accepted standard protocol was used in a replicated sampling design to apply statistical analyses to the resulting data set and allow for comparison with other studies in Brazil. Spiders were sorted to family level and counted; the adult spiders further identified to species if possible or classified as morphospecies with the help of several spider specialists.
