Olive pomace (OP) is a valuable food byproduct that contains natural phenolic compounds with health benefits related to their antioxidant activities. Few investigations have been conducted on OP from the United States while many studies on European OP have been reported. OP of Arbequina, the most common cultivar from California, was collected and extracted by water, 70% methanol and 70% ethanol, followed by purification using macroporous absorbing resin. Results showed that the extractable total phenolic content (TPC) was 36–43 mg gallic acid equivalents (GAE)/g in pitted, drum-dried defatted olive pomace (DOP), with major contributions from hydroxytyrosol, oleuropein, rutin, verbascoside, 4-hydroxyphenyl acetic acid, hydroxytyrosol-glucoside and tyrosol-glucoside. Macroporous resin purification increased TPC by 4.6 times the ethanol crude extracts of DOP, while removing 37.33% total sugar. The antioxidant activities increased 3.7 times Trolox equivalents (TrE) by DPPH and 4.7 times TrE by ferric reducing antioxidant power (FRAP) in the resin purified extracts compared to the ethanol crude extracts. This study provided a new understanding of the extraction of the bioactive compounds from OP which could lead to practical applications as natural antioxidants, preservatives and antimicrobials in clean-label foods in the US.

Cognitive infocommunications (CogInfoCom), is an emerging interdisciplinary research field that has recently started to appear in the context of theoretical, R&D, and industryoriented projects. CogInfoCom deals with novel approaches to extend the cognitive capabilities of human users through the artificial cognitive capabilities of infocommunications devices, enabling them to interact more flexibly with IT infrastructure. Two key points must be considered when asking why the emergence of CogInfoCom is not only timely but also necessary. First of all, the infocommunications industry is experiencing trends that are resulting in the gradual appearance of artificial cognitive capabilities ? capabilities directed towards a broadened scope covering the sensing and processing of unstructured data. Secondly, future users of infocommunications devices will expect both to be able to access these artificial cognitive capabilities in their everyday activities and to be able to merge them with their own cognitive capabilities. They will thus be able to apply them flexibly ? through their infocommunications devices ? in a wide range of applications in both physical and virtual contexts. This Special Issue on Cognitive Infocommunications contains extended versions of key ideas presented at CogInfoCom conferences. The table of contents alone will demonstrate to the reader the broad scope of theoretical considerations and practical applications that underlie current and emerging CogInfoCom research. It is our hope that this Special Issue ? along with the CogInfoCom conference series ? will contribute to providing a scientific forum for researchers from areas related to CogInfoCom and beyond, so that they may be able to develop stronger cooperation and create a more common language in order to produce useful synergies, and in order to fully meet the interdisciplinary challenges that underlie CogInfoCom.

In present day families a car fulfills utilitarian functions: it enables them to get to work, to drive children to school, to go on holiday, etc. However, the car has long ceased to be perceived, if ever ascribed to this function, as an object serving an efficient moving from “point A to point B.” The car has several symbolic meanings: the car may be a symbol of the economic status, a symbol of power, a reflection of one’s lifestyle, and so on. The aim of this article is to characterize the symbolic meanings of the car, its practical applications, as well as other functions of the car in the present day family. My theoretical considerations are primarily conducted in reference to the literature on sociology/anthropology of objects, sociology of the family as well as cultural gender studies. The article also presents results of the analysis of the content as well as the semiological analysis of advertisements of SUVs placed in official webpages of motor car concerns in Poland in 2014. Key words: car, family, symbolic meanings of car, utilitarian functions of car, advertisement
