People use at least two strategies to solve the challenge of understanding another person's mind: inferring that person's perspective by reading his or her behavior (theorization) and getting that person's perspective by experiencing his or her situation (simulation). The five experiments reported here demonstrate a strong tendency for people to underestimate the value of simulation. Predictors estimated a stranger's emotional reactions toward 50 pictures. They could either infer the stranger's perspective by reading his or her facial expressions or simulate the stranger's perspective by watching the pictures he or she viewed...

A highly robust metal-organic framework (MOF) constructed from Zr6 oxo clusters and Fe(III) porphyrin linkers, PCN-223-Fe was investigated as a heterogeneous catalyst for oxygen reduction reaction (ORR). Films of the framework were grown on a conductive FTO substrate and showed a high catalytic current upon application of cathodic potentials and achieved high H2O/H2O2 selectivity. In addition, the effect of the proton source on the catalytic performance was also investigated.

We report the photo-induced degradation of and cargo release from a nanoscale metal-organic framework (nMOF) incorporating photo-isomerizable 4,4'-azobenzenedicarboxylate (AZB) linkers. The structure matches a UiO-type framework where 12 4,4'-azobenzenedicarboxylate moieties are connected to a Zr6O4(OH)4 cluster, referred to as UiO-AZB. Due to the incorporation of photo-isomerizable struts, the degradation of UiO-AZB is accelerated by irradiation with white light (1.3 ± 0.1% h(-1) under dark conditions vs...

Dizziness is a common yet imprecise symptom. It was traditionally divided into four categories based on the patient's history: vertigo, presyncope, disequilibrium, and light-headedness. However, the distinction between these symptoms is of limited clinical usefulness. Patients have difficulty describing the quality of their symptoms but can more consistently identify the timing and triggers. Episodic vertigo triggered by head motion may be due to benign paroxysmal positional vertigo. Vertigo with unilateral hearing loss suggests Meniere disease...

OBJECTIVE: To investigate the effectiveness of unilateral posterior semicircular canal (PSCC)-plugging surgery for patients with intractable bilateral PSCC-type benign paroxysmal positional vertigo (P-BPPV). METHODS: From July 2011 to December 2015, we diagnosed 136 patients with P-BPPV. Of these, 3 patients had bilateral P-BPPV, and in 2 of the 3, the condition had been refractory to conservative treatment for more than 1 year. We planned a staged PSCC-plugging surgery for these 2 patients; initially one side was treated, and the contralateral side was treated 6 months later...

Water oxidation, a key component in artificial photosynthesis, requires high overpotentials and exhibits slow reaction kinetics that necessitates the use of stable and efficient heterogeneous water-oxidation catalysts (WOCs). Here, we report the synthesis of UiO-67 metal-organic framework (MOF) thin films doped with [Ru(tpy)(dcbpy)OH2 ](2+) (tpy=2,2':6',2''-terpyridine, dcbpy=5,5'-dicarboxy-2,2'-bipyridine) on conducting surfaces and their propensity for electrochemical water oxidation. The electrocatalyst oxidized water with a turnover frequency (TOF) of (0...

CONCLUSION: The Li maneuver is a safe, effective, and simple repositioning method for the treatment of BPPV. It is simple to master and exerts an exact effect. As a rapid repositioning method, the Li maneuver can result in reduced treatment times and increased treatment efficacy, and is, therefore, especially suitable for patients with limited cervical spine movement. OBJECTIVE: To compare the short-term efficacies of the Li and Epley maneuvers in treating posterior canal benign paroxysmal positional vertigo (PC-BPPV)...

It is a fundamental human need to secure and sustain a sense of social belonging. Previous research has shown that individuals who are lonely are more likely than people who are not lonely to attribute humanlike traits (e.g., free will) to nonhuman agents (e.g., an alarm clock that makes people get up by moving away from the sleeper), presumably in an attempt to fulfill unmet needs for belongingness. We directly replicated the association between loneliness and anthropomorphism in a larger sample (N = 178); furthermore, we showed that reminding people of a close, supportive relationship reduces their tendency to anthropomorphize...

BACKGROUND: Benign paroxysmal positional vertigo (BPPV) is a condition with recurrent attacks in a significant proportion of patients. The present case- control study was conducted to assess the influence of serum vitamin D normalization on recurrent attacks of vitamin D deficient patients. METHODS: Diagnosis of BPPV was made based on history and clinical examination and exclusion of other conditions. Serum 25-hydroxy vitamin D (25-OHD) was measured using ELISA method and a levels of < 20 ng/ml was considered a deficiency of vitamin D...

Treating a human mind like a machine is an essential component of dehumanization, whereas attributing a humanlike mind to a machine is an essential component of anthropomorphism. Here we tested how a cue closely connected to a person's actual mental experience-a humanlike voice-affects the likelihood of mistaking a person for a machine, or a machine for a person. We predicted that paralinguistic cues in speech are particularly likely to convey the presence of a humanlike mind, such that removing voice from communication (leaving only text) would increase the likelihood of mistaking the text's creator for a machine...

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is the most common peripheral cause of vertigo. It can be defined as transient vertigo induced by rapid changes in head position associated with a characteristic paroxysmal positional nystagmus. The aim of this study was to search for the possible role of oxidative stress and inflammatory mediators in the pathogenesis of BPPV. MATERIALS AND METHODS: Total antioxidant status as well as paraoxonase, tumor necrosis factor alpha, interleukin (IL) 6, and IL-1β levels were evaluated in peripheral venous serum samples of 30 BPPV and 30 control patients...

Few biases in human judgment are easier to demonstrate than self-righteousness: the tendency to believe one is more moral than others. Existing research, however, has overlooked an important ambiguity in evaluations of one's own and others' moral behavior that could lead to an overly simplistic characterization of self-righteousness. In particular, moral behavior spans a broad spectrum ranging from doing good to doing bad. Self-righteousness could indicate believing that one is more likely to do good than others, less likely to do bad, or both...

Benign paroxysmal positional vertigo (BPPV) is the most common cause of vestibular vertigo. It is caused by dislodged otoconia that enters the semicircular canals. Its main symptom is relapsing positional vertigo. The provocative tests, in particular the Dix-Hallpike maneuver, are used to confirm the diagnosis. In case of positive result of the test, one of the maneuvers is peformed depending on the affected semicircular canal, for instance the Epley maneuver. It is important to differentiate BPPV from the vertigo of central origin...

Benign paroxysmal positional vertigo (BPPV) is probably common cause of vertigo. A total of 205 cases reported to ENT OPD for vertigo. Of these 43 patients were found to suffer from BPPV and in our experience BPPV is common condition. BPPV was more common in age group of 4th and 7th decades. The youngest patient reported was 41 years and the oldest patient was 78 years with a mean of 56.5. In this group there were 16 females and 27 males. This is a retrospective case study of 205 cases presenting with vertigo...

Logically, group members cannot be responsible for more than 100% of the group's output, yet claims of responsibility routinely sum to more than 100%. This "over-claiming" occurs partly because of egocentrism: People focus on their own contributions, as focal members of the group, more than on others' contributions. Therefore, we predicted that over-claiming would increase with group size because larger groups leave more contributions from others to overlook. In 2 field studies, participants claimed more responsibility as the number of academic authors per article and the number of MBA students per study group increased...
