If fostering emotional intelligence and empathic imagination and solving ethical dilemmas were discussed openly and taught methodically in K-12 mainstream (“typical”) classrooms, would we need metal detectors at the inner city schools’ entrances, and would we need special anti-bullying programs, which intend to correct bullying culture, rather than build a new one, based on kindness, openness, and consideration for others?Will we learn lessons from the Columbine High School and the Sandy Hook Elementary School massacres, and radically change educational system, to incorporate empathic imagination and emotional intelligence into mainstream K-12 curriculum – as a mandatory discipline – instead of leaving this important part of learning and character formatting only to the special education sphere?This symposium represents a collaborative effort of four educators from various disciplines who crossed boundaries to emphasize and foster emotional intelligence and empathic imagination throughout the K-12 curriculum.The following are the parts of the proposed multidisciplinary panel:– multidisciplinary approach to revolutionary education, or paradigm shift towards fostering emotional intelligence and empathic imagination across the mainstream curriculum;– Descartes’ error, the triune brain, and neurobiology of emotional intelligence;– changing our consciousness: imagining the emotional experience of the other;– teaching social skills and play therapy in schools: report from the trenches of special education;– examining cultural artifacts, tools for personal, emotional, and academic development;– growing kind kids: mindfulness and the whole-brained child;– Emotional Imprint™ at the street squash: ‘If you talk, you don’t kill.’Disclosure of interestThe author has not supplied his declaration of competing interest.

The subject of the research are 5 spearheads from the villages: Leszczków, Rytwiany, Szczeka and Lubienia, in the Świętokrzyskie voivodeship. The artefacts, apart from the one from Szczeka, were found by accident, probably in the course of illegal searches with the use of metal detectors. The spearheads should be dated to the younger Pre-Roman period and the Roman period. They probably come from the destroyed cremation graves from the unknown so far cemeteries of the Przeworsk culture.

<p>Acts of terrorism are crimes and serious violations of human rights, also the threat of violence that can cause mass casualties and destruction of vital strategic objects. This is an urgent threat that needs to be prepared by designing a bomb detector conceptual design as anticipation of the threat of terrorism in public services. This study aims to obtain operational requirements and conceptual design of bomb detectors as detection of terrorism threats in public services. This study uses a mixed-method with a systems engineering approach and a life cycle model to produce a technological design. The results of operational requirements are sensors, standards, artificial intelligence, integration capability, reliability, calibration mode, portable, and easy to maintain. The configuration design is divided into three stages, namely, 1) sensors including a camera security surveillance system vector image, metal detectors, explosive detectors, and A-jamming; 2) as a processing device, processes an order with the help of an artificial intelligence system; and 3)  a security computer (surveillance), early warning, and mobile information to provide information to related agencies, especially the anti-terror unit.</p>

The subject of the monograph, published as the 10th volume of the Saved Archaeological Heritage series, are the results of rescue excavations on a cemetery from the period of Roman influence on the Vistula River near Magnuszew in southern Mazovia (Poland), carried out several years ago at the initiative of the Museum in Radom. This necropolis, like many similar ones throughout the country, was systematically destroyed as a result of agricultural activities, and in recent years also through illegal prospection with the use of metal detectors. Archaeologists, with the cooperation of numerous volunteers, managed to protect against further destruction about 60 graves (urned and urnless) from the period between the 1st century BC and the 3rd century CE. These are an evidence of the settlement of the region by people whose material traces are referred to in the archaeological nomenclature as the Przeworsk culture (associated mainly with the Germanic tribes). The cinerary graves were equipped with ceramics, metal parts of clothing, tools, less often weapons, glass beads, imported vessels or dice. Among the forms of graves, the so-called groove object stands out: a kind of rectangular grave feature tied with survival to the beginnings of our era of Celtic traditions, arriving here from northern Małopolska. In addition to the standard catalogue with the description of graves, pottery and small finds, and very detailed illustration plates, the monograph includes an analysis of material culture and forms of burial, photographs of selected finds and very extensive specialist reports. The latter include both osteological materials (anatomo-anthropological analysis, analysis of animal bones placed in the graves), as well as other ecofacts and individual categories of furnishings (glass, faience, iron and bronze objects). The whole is complemented by clear plans with the location of graves and artifacts in the necropolises, as well as with the results of non-invasive research going far beyond the excavated area and of key importance for further in situ protection of this extremely valuable monument.

The conservation of France’s archaeological heritage has been seriously threatened for several decades by users of metal detectors. To curb this scourge, which undermines research and conservation of the remains, the State implements educational and repressive measures.

The article is an experience of regional study of Roman coins finds on the territory of Eastern Europe. The basic information about them was collected and published in the middle of the 20th century. However, today this source base has significantly expanded. Basically, due to the use of metal detectors during archaeological research and, unfortunately, for illegal purposes (such finds are called «less reliable», their use is obligatory, however, provided a critical approach to information). Analysis of the main categories of Roman coins finds in the region made it possible to distinguish features in their distribution. Basically, Volhynia are is outside the concentration of the main categories of finds of Roman coins in Eastern Barbaricum: Roman republican coins, 1—2nd c. AD denarii, 1—3rd c. AD aurei, 2—3rd AD bronze provincial coins, antoniniani and bronze and silver emissions of 4th c. AD. Nevertheless, the concentration of the 4th c. AD Roman gold medallions is associated with this region (in article published a new find of such coin), which indicates here the existence of the centre of the barbarous elite. In general, the numismatic material of the Volhynia region is typical for the territory of the right bank of Dnieper. At the same time, do not forget that Volhynia, like all territory of Eastern Barbaricum, in Roman period was part of the German cultural circle, in which Roman coins were universal.

A major drawback of all existing tracer techniques for monitoring shingle movement, except that of labelling with radioactive isotopes, is that tracer recovery rates are invariably low, (commonly less than 15% of the total injected) because recovery is limited to the beach surface. Investigations were made into the possibilities of developing a new tracer that might overcome this problem. The paper describes the results of, and the conclusions drawn from two trial field experiments carried out using metal tracer pebbles. These had specific gravities, size and shape similar to the indigenous beach pebbles, and were recovered both on and beneath the beach surface using metal detectors. By assessing the relative merits and drawbacks of the technique it was concluded that the use of metal pebbles as tracers for shingle beaches is more practical than other methods for most tracing purposes. At present the technique is best suited to investigations ranging in length from a few days to a few months and requiring small to medium-scale injections of 5000 tracer pebbles or less. The considerable scope for the further development and application of the technique is discussed.
