Good fortune but bad luck? Predictable versus unpredictable gains and losses in risky choice
Authors: Ranieri Andrea Y. , Kauffman Sandra S. , Schneider Sandra L. 
Published: February 2019

AbstractThis study examines the effects of two different types of good and bad experiences on risk‐taking preferences: fortune and luck. We define fortune as a relatively stable positive or negative context within which choices are made and luck as a more unpredictable series of better or worse outcomes. With the use of a lottery‐based paradigm, fortune was operationalized as a preponderance of all‐gain or all‐loss two‐outcome option pairs within a larger set of mixed‐outcome control lotteries. Luck was operationalized as the experienced frequency of better versus worse outcomes when playing the lotteries. We predicted that fortune and luck would lead to opposite risk‐taking tendencies within control lotteries. An assimilation effect of fortune was predicted, with risk‐averse preferences for control lotteries when surrounded by good fortune and risk‐seeking preferences when surrounded by bad fortune. In contrast, we expected that high rates of success with good luck would lead to risk‐seeking preferences, whereas low rates of success with bad luck would yield risk‐averse preferences. Our predictions for fortune were confirmed; however, there was no evidence of any effect on risk taking based on experiencing good versus bad luck. Moreover, we observed a striking disconnect between impressions of the experience and risk‐taking behavior. Both identification and attributions of luck and fortune were highly correlated with the number of gain outcomes that participants experienced but were uncorrelated with risk taking. We review these surprising findings considering several prominent theories of risk‐taking behavior, particularly drawing attention to the differential roles of predecisional and postdecisional information in choice.
What you are confident of determines your choices in context: Confidence in yourself versus in your ability
Authors: Wang Yawei , Chang Yaping 
Published: February 2019

AbstractThe notion that consumers' preference is constructed by decision context is well established. Two of such salient manifestations are compromise effect and attraction effect. Although literature has explored the moderators of these effects from the perspective of a decision maker, little is known about whether a significant difference exists between the effects of individual differences as a situational state and as a stable personality. This article approaches this question by examining how specific self‐confidence and general self‐confidence shape consumer's preference for context options. Four studies find that compromise effect is greater for consumer with high specific self‐confidence, whereas attraction effect is greater for consumer with low specific self‐confidence. The two context effects are greater for consumers with low general self‐confidence only in the presence of social influence. In addition, low (vs. high) general self‐confidence strengthens (vs. weakens) the impact of specific self‐confidence on context effects under this condition. This article concludes by discussing the theoretical and practical implications of the findings.

AbstractGlibenclamide (GB), as a sulfonylurea‐based medication is commonly prescribed for the treatment of type 2 diabetes. Due to its increasing consumption, there is a need to develop a simple, fast, and reliable detection method to follow its concentration in pharmaceutical and biological samples. Herein, a novel fluorometric method is developed for the sensitive measurement of GB. The method is based on the enhancing effect of GB on the fluorescence emission of mercaptopropionic acid (MPA) capped cadmium telluride quantum dots (CdTe QDs). QDs were synthesized in aqueous solution and were characterized by fluorescence spectroscopy, transmission electron microscopy (TEM), X‐ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT‐IR). Fluorescence intensity of QDs was enhanced by adding GB in a very low concentration. The effect of operative factors such as pH, buffer, contact time and concentration of CdTe QDs were investigated and in the optimized condition, a linear increase was achieved for the emission intensity of QDs by increasing GB concentration in the range 49–345 ng mL−1, with a detection limit of 17.84 ng mL−1. The offered method has an acceptable precision (relative standard deviations were < 2.8%) and was satisfactorily applied for the determination of GB in pharmaceutical products and human urine samples.

AbstractPedagogical innovation involving smartphone technology may offer teachers the opportunity to create an environment of engaging learning in laboratories. In this paper, we outline how to use Socrative Student Response by Mastery Connect, a variation of a real‐time audience response system. We hypothesized that using this application as an audience response system can enhance learning and identify student knowledge gaps in chemistry laboratory classes. In order to explore the relationships among factors and the educational effectiveness of Socrative, data from a graduate‐level chemistry course students were investigated. Before and after laboratory classes, experimental subjects completed an audience response system quiz using Socrative application in their mobile devices. Students felt that the method enhanced their learning process whereas teachers reported that it improved academic performance and the relationships between teachers and students. Socrative can be considered as a powerful tool to dynamize and evaluate chemistry laboratory practices.

AbstractThe consumer behavior literature shows that men are externally focused and women are internally focused consumers. The authors conduct three studies to test gender differences in the use of media‐posted public ratings for deciding whether to recommend branded entertainment films. The Study 1 results indicate that men are more (less) likely to recommend films that have high (low) star ratings, but women are equally likely to recommend films regardless of star ratings. In an interesting twist, Study 2 results show that if women are momentarily distracted by being made more aware of their surroundings, they process information similarly to men and are more persuaded by public ratings. In Study 3, the authors replicate and extend the findings by including a no‐star control group and examining additional variables—film and brand attitudes and recommendations—with a no star rating control group. The overall results show that men (women) are more (less) likely to look to public ratings for forming film and brand attitudes and recommendations.

Published: February 2019

AbstractBulkily substituted organodihydrogermylium and ‐stannylium cations [Ar*EH2]+ (E=Ge, Sn; Ar*=2,6‐Trip2C6H3, Trip=2,4,6‐triisopropylphenyl) were characterized as salts of the weakly coordinating perfluorinated alkoxyaluminate anion [Al{OC(CF3)3}4]−. At room temperature, the stannylium cation liberates hydrogen to generate the low valent organotin cation [Ar*Sn]+. In contrast, the dihydrogermylium cation transfers the hydrogen atoms to an aryl moiety of the terphenyl ligand and oxidatively adds either hydrogen under an atmosphere of hydrogen or a sp2 CH unit of the 1,2‐difluorobenzene solvent.

Published: February 2019

AbstractAlthough ultimately not isolable for X‐ray structural characterization, the free perfluorinated trityl cation was shown to be observable in neat triflic acid, which represents milder conditions than previous reports of this cation in “magic acid” or oleum. A triflate‐bound species could be generated in organic solvents using stoichiometric amounts of triflic acid and was shown to be synthetically viable for hydride abstraction from Et3SiH. It was demonstrated that the para‐position on the ‐C6F5 rings is the primary point of attack for decomposition of the cation.

Published: February 2019

AbstractA tungsten silylyne complex having a W≡Si triple bond reacted with two molecules of aldehydes at room temperature to give W−Si−O−C four‐membered metallacycles by [2+2] cycloaddition and subsequent formyl hydrogen transfer from one aldehyde molecule to another. Upon heating to 70 °C, the four‐membered metallacycles underwent metathesis‐like fragmentation cleanly to afford carbyne complexes and “silanoic esters,” in a manner similar to that of metallacyclobutadiene, an intermediate of alkyne metathesis reactions, and dimerization of the latter products gave 1,3‐cyclodisiloxanes. The “silanoic ester” was also trapped by pivalaldehyde to give a [2+2] cycloaddition product in high yield.

BackgroundThe adjuvanted recombinant zoster vaccine (RZV) has demonstrated >90% efficacy against herpes zoster in adults ≥50 years of age and 68% efficacy in autologous hematopoietic stem cell transplant recipients ≥18 years of age. We report the immunogenicity and safety of RZV administered to patients with solid tumors (STs) before or at the start of a chemotherapy cycle.MethodIn this phase 2/3 observer‐blind, multicenter study (NCT01798056), patients with STs who were ≥18 years of age were randomized (1:1) to receive 2 doses of RZV or placebo 1‐2 months apart and stratified (4:1) according to the timing of the first dose with respect to the start of a chemotherapy cycle (first vaccination 8‐30 days before the start or at the start [±1 day] of a chemotherapy cycle). Anti‐glycoprotein E (gE) antibody concentrations, gE‐specific CD4+ T cell frequencies, and vaccine response rates (VRRs) were assessed 1 month after dose 1 and 1 and 12 months after dose 2. Reactogenicity and safety were assessed in the total vaccinated cohort through 12 months after dose 2.ResultsThere were 232 participants in the total vaccinated cohort, 185 participants in the according‐to‐protocol cohort for humoral immunogenicity, and 58 participants in the according‐to‐protocol cohort for cell‐mediated immunogenicity. Postvaccination anti‐gE antibody concentrations, gE‐specific CD4+ T cell frequencies and VRRs were higher in RZV recipients than in placebo recipients. Solicited adverse events (AEs) were more frequent among RZV recipients than placebo recipients. Incidence of unsolicited AEs, serious AEs, fatalities, and potential immune‐mediated diseases were similar between RZV and placebo recipients.ConclusionRZV was immunogenic in patients with STs receiving immunosuppressive chemotherapies. Humoral and cell‐mediated immune responses persisted 1 year after vaccination. No safety concerns were identified.

BackgroundStopping tyrosine kinase inhibitor (TKI) treatment has become a realistic and safe objective for patients who have chronic myeloid leukemia (CML). Both a sustained deep molecular response (sDMR) and the lack of a molecular recurrence after TKI discontinuation are required to reach a durable treatment‐free remission (TFR).MethodsThe potential predictive role of BCR‐ABL transcripts in attaining an sDMR and a TFR was analyzed in a strictly consecutive, unselected series of 194 patients who were diagnosed and treated with TKIs at the authors’ center.ResultsOf 173 fully evaluable patients, 67 (38.7%) had the e13a2 transcript, and 106 (61.3%) had the e14a2 transcript. Complete cytogenetic and major molecular remissions were not affected, whereas the achievement of both a DMR (P = .008) and an sDMR (P = .004) was favored significantly in patients who had the e14a2 transcript. After a median of 68 months, the sDMR rate was 39.6% in those with the e14a2 transcript and 19.4% in those with the e13a2 transcript. In addition to transcript type, both the early achievement of a molecular response and starting treatment with a second‐generation TKI positively affected the attainment of an sDMR in multivariate analysis. The use of a second‐generation TKI as frontline treatment increased the sDMR rate in both transcript types. However, in patients who had the e13a2 transcript, the probability of attaining an sDMR was 37% after 60 months and did not increase further despite continuing therapy. Among 51 of 60 patients who attained an sDMR after discontinuing TKIs, 24 experienced a molecular relapse, but all regained molecular remission after resuming TKI treatment. Again, transcript type influenced TFR maintenance (P = .005), because only 2 patients (3%) with the e13a2 transcript enjoyed a durable TFR compared with 25 (23.5%) of those with the e14a2 transcript.ConclusionsThe e13a2 transcript hinders the achievement of deep responses and the possibility of stopping TKI treatment in patients with CML.

BackgroundTreatment decisions for patients with early‐stage breast cancer often involve discussions with multiple oncology providers. However, the extent to which primary care providers (PCPs) are involved in initial treatment decisions remains unknown.MethodsA stratified random sample of PCPs identified by newly diagnosed patients with early‐stage breast cancer from the Georgia and Los Angeles Surveillance, Epidemiology, and End Results registries were surveyed (n = 517; a 61% response rate). PCPs were asked how frequently they discussed surgery, radiation, and chemotherapy options with patients; how comfortable they were with these discussions; whether they had the necessary knowledge to participate in decision making; and what their confidence was in their ability to help (on 5‐item Likert‐type scales). Multivariate logistic regression was used to identify PCP‐reported attitudes associated with more PCP participation in each treatment decision.ResultsIn this sample, 34% of PCPs reported that they discussed surgery, 23% discussed radiation, and 22% discussed chemotherapy options with their patients. Of those who reported more involvement in surgical decisions, 22% reported that they were not comfortable having a discussion, and 17% did not feel that they had the necessary knowledge to participate in treatment decision making. PCPs who positively appraised their ability to participate were more likely to participate in all 3 decisions (odds ratio [OR] for surgery, 6.01; 95% confidence interval [CI], 4.16‐8.68; OR for radiation, 8.37; 95% CI, 5.16‐13.58; OR for chemotherapy, 6.56; 95% CI, 4.23‐10.17).ConclusionsA third of PCPs reported participating in breast cancer treatment decisions, yet gaps in their knowledge about decision making and in their confidence in their ability to help exist. Efforts to increase PCPs’ knowledge about breast cancer treatment options may be warranted.

Published: February 2019

SummaryIn this paper, we develop and investigate the parallel numerical algorithms for three different state‐of‐the‐art numerical methods for solving the non‐local problems described by fractional powers of elliptic operators. These methods transform the non‐local problem into some local differential problems of elliptic or parabolic type. A two‐level parallelization approach is applied to construct the efficient parallel algorithms using the domain decomposition and master‐slave methods, to deal with the increase in computational complexity. We show and compare the serial and parallel solution times that are required to achieve similar accuracy of the solution using different algorithms. Results of extensive convergence tests are presented solving a three‐dimensional test problem with known decrease of the solution's convergence rate depending on the fractional power coefficient. We analyze and discuss the non‐trivial question, which parallel algorithm is recommended to achieve certain accuracy for the given fractional power coefficient.

Published: February 2019

AbstractThe objectives of this study is to identify methods for objectively assessing masticatory performance (MP) and to evaluate their measurement properties. A secondary objective was to identify any reported adverse events associated with the methods to assess MP. Bibliographic databases were searched, including MEDLINE, Embase, Web of Science Core Collection, Cochrane, and Cinahl databases. Eligible papers that satisfied predefined inclusion and exclusion criteria were appraised independently by two investigators. Four other investigators independently appraised any measurement properties of the assessment method according to the consensus‐based standards for the selection of health measurement instruments checklist. The qualities of the measurement properties were evaluated using predefined criteria. The level of evidence was rated by using data synthesis for each MP assessment method, where the rating was a product of methodological quality and measurement properties quality. All studies were quality assessed separately, initially, and subsequently for each method. Studies that described the use of identical assessment method received an individual score, and the pooled sum score resulted in an overall evidence synthesis. The level of evidence was synthesized across studies with an overall conclusion, that is, unknown, conflicting, limited, moderate, or strong evidence. Forty‐six out of 9,908 articles were appraised, and the assessment methods were categorized as comminution (n = 21), mixing ability (n = 23), or other methods (n = 2). Different measurement properties were identified, in decreasing order construct validity (n = 30), reliability (n = 22), measurement error (n = 9), criterion validity (n = 6), and responsiveness (n = 4). No adverse events associated with any assessment methods were reported. In a clinical setting or as a diagnostic method, there are no gold standard methods for assessing MP with a strong level of evidence for all measurement properties. All available assessment methods with variable level of evidence require lab‐intensive equipment, such as sieves or digital image software. Clinical trials with sufficient sample size, to infer trueness and precision, are needed for evaluating diagnostic values of available methods for assessing masticatory performance.
