How to Prevent Crowdsourcing Disasters and Leverage Positive Side Effects of Open Innovation
Authors: Füller Johann , Hutter Katja , Kröger Niclas 
Published: May 2020

Abstract
The gains from crowdsourcing can be high, but so can the risks. Contests may become a nightmare for the sponsoring organization if the innovators do not behave as planned. When contest managers act in undesirable ways from a participant’s perspective, community members might bash, shame or ridicule a company. To prevent “firestorms” – negative, often highly emotional posts in social media that are eagerly taken over by traditional media – project sponsors need to ensure fairness throughout the contest. The value of the price and the procedures for selecting winners must be fair and transparent – and companies need to stick to predefined rules. Organizations that succeed in keeping their community motivated might not only benefit from new ideas, but also from additional positive effects. Devoting time, skills and personal engagement to developing new ideas for a company favors intense relationships, and participants often become passionate brand followers. By communicating openly about their approach of open innovation, companies can also foster their innovative image.

Published: May 2020

Background:
We, here, describe the case of Systemic Lupus Erythematosus (SLE) with pancytopenia, refractory to steroids, immunosuppressive therapy, and plasmapharesis that ultimately responded to intravenous immunoglobulins (IVIG). To the best of our knowledge, very few cases of this type have been reported in literature.

Case presentation:
A 40-year-old female presented with complaints of hematemesis, hematochezia, gum bleed, epistaxis, menorrhagia, and fever. After careful examination and investigation she was diagnosed with SLE associated with pancytopenia refractory to conventional means of treatment. Pancytopenia responds normally to steroids and immunosuppressive agents in these patients however our patient responded only to IVIG.

Conclusion:
This case report highlights the fact that early use of Intravenous immunoglobulins in patients of SLE with severe and refractory pancytopenia can prevent morbidity and mortality.

Effect of Partial Dependence of Photopeak Data on The Calculations of NaI(Tl) Detector Spectrum
Authors: Ahmad Elawi Mahmoud , Taha Ahmad Hafsa 
Published: May 2020

Partial dependence of photopeak data of ɣ-ray energies is considering apart of peak channels after subtracting background (including Compton distribution) and obtaining symmetric Gaussian distribution, then considering this part to obtain other total data of peak. This was investigated by using NaI(Tl) detector with Eu-152, Ra-226 and Cs-137 point sources. For the isolated peaks of Eu-152, Gaussian shape is obtained, and the areas between ±σ and ±0.5σ were determined and efficiency is obtained. The calculated transformation to total data of peaks gave excellent agreement with the ordinary case. The overlap between the two peaks at 609.3 (Ra-226) and 661.6 keV (Cs-137) is studied with using σ values from data when sources are separated, and counts in peaks centroids. The data of each peak is "restored" and compared with that when sources are separated and gave a 98% agreement. Also the overlap between the two peaks at 1120 and 1238 keV (Ra-226) is studied with adopting the σ values from the shape calibration curve of Eu-152 and centroid counts in the same way as for the Ra-226 and Cs-137 case. The resultant peaks areas are compared with those obtained from efficiency calibration curve of Eu-152. However results here are of lower agreement.

Current and prospective business characteristics enter the market climate. So today we live in four eras at the same time, the globalization of the economic period, the period of information technology, the strategic efficiency management era, and the revolutionary era in management. We must discover the characteristics of each period and bring it against management principles. Based on the results of the assessment, it is known that Kademangan Village not only has abundant natural potential, but is also supported by skilled Human Resources (HR), especially in handicrafts and food preparations. Even so the living conditions of the people, especially the economic aspects, are not sufficient. This is caused by several factors such as the still poor quality of human resources and inadequate village infrastructure. For example, the community of handicrafts and food preparations have not been able to produce different products and of good quality so that they have high selling points. Considering these various conditions, the PKM (Student Activity Center) activities are directed at the economic aspect by organizing training for community service activities with the theme "Entrepreneurship Training to Improve Community Economy in Kademangan Village, Mojoagung District, Jombang Regency".
