Raising the value of research studies in psychological science by increasing the credibility of research reports: the transparent Psi project.

The low reproducibility rate in social sciences has produced hesitation among researchers in accepting published findings at their face value. Despite the advent of initiatives to increase transparency in research reporting, the field is still lacking tools to verify the credibility of research reports. In the present paper, we describe methodologies that let researchers craft highly credible research and allow their peers to verify this credibility. We demonstrate the application of these methods in a multi-laboratory replication of Bem's Experiment 1 (Bem 2011 J. Pers. Soc. Psychol. 100, 407-425. (doi:10.1037/a0021524)) on extrasensory perception (ESP), which was co-designed by a consensus panel including both proponents and opponents of Bem's original hypothesis. In the study we applied direct data deposition in combination with born-open data and real-time research reports to extend transparency to protocol delivery and data collection. We also used piloting, checklists, laboratory logs and video-documented trial sessions to ascertain as-intended protocol delivery, and external research auditors to monitor research integrity. We found 49.89% successful guesses, while Bem reported 53.07% success rate, with the chance level being 50%. Thus, Bem's findings were not replicated in our study. In the paper, we discuss the implementation, feasibility and perceived usefulness of the credibility-enhancing methodologies used throughout the project.

Comparative Study on High Strain Rate Fracture Modelling Using the Application of Explosively Driven Cylinder Rings.

The effect of different constitutive modelling choices is crucial under a high strain rate as encountered in ballistic applications. Natural fragmentation of explosively driven cylinder rings is chosen as a simplified example to describe the ability of numerical simulations to describe fractures. The main research interests are the importance of (i) material imperfections, (ii) the accuracy of fracture models vs. damage models, (iii) the plasticity algorithm (stress update), (iv) the introduction of a triaxiality cutoff criterion to the damage models, and (v) different constitutive models (plasticity and damage). Due to the complexity of the propagation and coalescense of multiple cracks in classical methods, smoothed-particle hydrodynamics (SPH) is used as a tailor-made method to discretise the model. An elasto-plasticity model, a damage model and an equation of state describe the material behaviour. The required material parameters are determined based on stress-strain curves from quasi-static and dynamic tests. The Johnson-Cook model, with and without a modification of the strain rate term, and the Rusinek-Klepaczko model are used to describe plasticity. These plasticity models are combined either with the Johnson-Cook, the Lemaitre, or the Dolinski-Rittel damage model and the Mie-Grüneisen equation of state. The numerical results show that (i) a random distribution of initial damage increases irregularity of cracks, and gives more realistic fragment shapes, (ii) a coupling of plasticity model and fracture criterion has only a small effect on the fracture behaviour, (iii) using an iterative plasticity solver has a positive effect on the fracture behaviour, although this effect is marginal, (iv) adding a triaxiality cutoff criterion to the damage models improves the predicted fragment masses in the numerical simulations significantly, and (v) good accordance between experiments and numerical simulations are found for the Dolinski-Rittel and Lemaitre damage model with both plasticity models.

Response of hemorrhagic bullous skin lesions of the breast secondary to primary systemic amyloidosis to a five-drug combination chemotherapy: a case report and review of the literature.

Two major types of amyloidosis are primary amyloidosis or amyloid light chain amyloidosis and secondary amyloidosis. Although amyloidosis involves a variety of organ systems including skin, the occurrence of bullous skin lesions is rare. Little is known about the mechanism of blister formation. These blisters are often hemorrhagic and typically occur in the oral mucosa. Only a few case reports have described skin involvement in systemic amyloidosis. The manifestation of bullous lesions on the breast in association with primary amyloidosis has not been previously reported. Therefore, we report a case of cutaneous hemorrhagic bullous of the breast secondary to primary systemic amyloidosis, which may be important for medical oncologists to be aware of this uncommon presentation of plasma cell dysrasias. Furthermore, this case only partially responded to the commonly used multiple myeloma-type regimen, the skin lesions responded completely to a five-drug combination chemotherapy regimen, utilizing immunomodulators, liposomal doxorubicin, cyclophosphamide, bortezomib, and dexamethasone, suggesting that a more aggressive modality of chemotherapy may be necessary to treat such cases.
