Reality is Broken: Why Games Make Us Better and How They Can Change the World Jane McGonigal. 2011. New York: Penguin Press, ss. 388

Abstract: Jane McGonigal jest światowej slawy specjalistką w zakresie badania i projektowania gier. Z wyksztalcenia doktor performance studies, pracuje obecnie w kalifornijskim Institute for the Future. Jako projektantka gier skupia sie przede wszystkim na grach internetowych angazujących tysiące uzytkownikow, ktorych wspolpraca prowadzi do wyksztalcenia sie zbiorowej (rozproszonej) inteligencji. Ma w swoim dorobku m.in. glośne projekty o zasiegu globalnym, na przyklad The Lost Ring na zamowienie Komitetu Olimpijskiego czy EVOKE! finansowane przez Instytut Banku Światowego. Wedlug McGonigal masowe spoleczności graczy kryją w sobie ogromny potencjal jako zasoby ludzkie, a ponadto same systemy gier zawierają skuteczne procedury motywujące do wysilku i optymalizujące ludzkie starania. Koronną ideą autorki jest zaprzegniecie gier, zwlaszcza internetowych, do rozwiązywania problemow rzeczywistego świata. W branzy projektantow gier wystąpienie McGonigal na Game Developers Conference w 2008 stanowilo przelom: tworcy i producenci gier uświadomili sobie potencjal (i poniekąd moralny obowiązek) uzywania gier pro publico bono. Oczywiście, juz wcześniej istnialy gry nastawione na pozytek pozarozrywkowy (Serious Games, Games With a Purpose, wszelkie gry edukacyjne, aktywizujące spolecznie, zwalczające stereotypy etc.). Jednak do 2008 bylo ich stosunkowo niewiele – w 2009 ruszyla lawina. Co wiecej, uzytecznośc gier zostala doceniona takze poza branzą. Ho m o Lu de ns 1 /(3 ) ( 20 11 )

Parasites in sympatric populations of native and invasive freshwater bivalves

Abstract: An increasing threat to local, native freshwater mussels (Unionida)—an ecologically important but globally alarmingly declining group—is the invasion by exotic bivalves. The Enemy Release Hypothesis predicts that introduced species should benefit from enemy-mediated competition because they are less likely to be harmed by natural enemies, such as parasites, than their native competitors. We investigated within-site differences in parasitism between sympatric native (tot. five spp.) and invasive (tot. three spp.) bivalves in eight northern European waterbodies, which harboured totally 15 parasite taxa. In paired comparisons using within-site averages, the mean number of parasite species in the native bivalves was 2.3 times higher, and the sum of parasite prevalences 2.4 times higher, than in the invasive bivalves. This may lead to enemy-mediated competitive release of invaders and contribute to the success of invasive freshwater bivalves, in general. However, while the invasive clam Corbicula fluminea was completely free from parasites, parasite parameters of the other invader, Sinanodonta woodiana, were relatively high, indicating that the role of parasites can be invader-specific and urges further research. Understanding the factors affecting success of freshwater bivalve invasions, such as parasitism, can aid invasion control and conservation of local, native (endangered) bivalves.

Guidelines for Stego/Malware Detection Tools: Achieving GDPR Compliance

Abstract: Never before has cybersecurity been as significant for societies as today; its importance is still on the rise as people rely on computer systems every day. Recently, the ever-growing issues of personal data being stolen or misused have been addressed by several legal regulations, the most significant of them being the General Data Protection Regulation (GDPR). The paper deals with a specific cybersecurity measure, malware/stegomalware detection. This solution, which is meant to protect personal data from being used in a way that breaks the GDPR, has to be GDPR-compliant itself. This work describes the GDPR regulation in detail, indicates the specific challenges that may arise when applying malware/stegomalware solutions, and provides several recommendations for ensuring compliance with the regulation.

Determination of mycotoxins, alkaloids, phytochemicals, antioxidants and cytotoxicity in Asiatic ginseng (Ashwagandha, Dong quai, Panax ginseng )

Abstract: Mycotoxins and selected hazardous alkaloids in the medicinal plants (Panax ginseng, Angelica sinensis, and Withania somnifera) and dietary supplements were determined. Purine alkaloids were found in majority of samples; however, isoquinoline alkaloids were less abundant than indole. The predominant alkaloids appear to be caffeine (purine group), harman (indole group) and berberine (isoquinoline). Examined medicinal plants and dietary supplements were contaminated by mycotoxins (especially ochratoxin A 1.72–5.83 µg kg−1), and many species of mold (e.g. Cladosporium, Eurotium, Aspergillus, Rhizopus, Penicillium). MTT cytotoxicity tests revealed that plant and supplements extracts exhibited medium or high cytotoxicity (only Dong quai—low). Moreover, antioxidant activity, total phenolics content and selected phytochemicals were analyzed by spectrophotometric and chromatographic methods. Quercetin and rutin were predominant flavonols (1.94-9.51 and 2.20–7.28 mg 100 g−1, respectively). Analysis of phenolic acids revealed—gallic acid, as the most abundant, except Panax ginseng, where ferulic acid was prevailing. The results were analyzed by chemometric methods (cluster analysis, ANOVA).
