Less identifiable but no less helpful: Face masks do not go along with selfish behavior

Covering the face with masks in public settings has been recommended since the start of the pandemic. Because faces provide information about identity, and that face masks hide a portion of the face, it is plausible to expect individuals who wear a mask to consider themselves less identifiable. Prior research suggests that perceived identifiability is positively related to prosocial behavior, and with two pre-registered field studies (total N = 5706) we provide a currently relevant and practical test of this relation. Our findings indicate that mask wearers and non-wearers display equivalent levels of helping behavior (Studies 1 and 2), although mask wearers have a lower level of perceived identifiability than those without a mask (Study 2). Overall, our findings suggest that claims that face masks are related to selfish behavior are not warranted, and that there is no practical link between perceived identifiability and prosocial behavior.

Pengembangan Media Pembelajaran Audio Visual Materi Bangun Ruang Sisi Datar di SMP Negeri 6 Mataram

The purpose of this research is to produce a learning audiovisual media that is suitable for the material of build a flat side room in SMP Negeri 6 Mataram. The method used in this research is according to Luther, is multimedia development life cycle (MDLC). MDLC have 6 steps, there are concept, design, material collecting, assembly, testing, and distribution. Field testing was used in this research are validation test, practical test, and test for the learning media’s effectiveness. In validation test, the result of this research is validated by some experts. The practical test was carried out by 2 practitioners and the test for effectiveness was based on the results of the questionnaire which were filled in by 74 students (37 students of class VIII and 37 students of grade IX). Instrumen indicators are based on the feasibility of the media according to Thorn. The results of the validation test showed an average score of 3.14, with a very good category. Meanwhile, the results of the practical test with an average score are 3.39 in the very good category, and the results of the effectiveness test with an average score of 2.86 in the good category. So it can be concluded that the audiovisual learning media that have been developed are suitable for use in learning mathematics.

Implementasi Metode Visual-Auditory-Kinestetik dalam Tari SigehPenguten sebagai Tarian Tradisi Lampung di UPTD SMPN 3 Metro

The purpose of learning the Sigeh Pengunten Dance with the VAK (Visual) learning method is to determine the extent to which students are able to demonstrate the Sigeh Penguten Dance according to what is taught by the teacher. The research method used is descriptive qualitative with a population of UPTD SMPN 3 Metro students and a sample size of 5 students. The results of this study are the learning process using the visual method, auditory kinesthetic in practice has increased in the first meeting to the eighth meeting. This can be seen from 3 aspects of VAK, namely visual and auditory in the form of students listening to teacher instructions and paying attention and seeing the teacher demonstrating the Sigeh penguten dance, namely the Lapah tebeng movement, Seluang going home, jong simpuh, sitting down, jong silo Ratu and Sembah, flashback, biting. , samber floated. Guuh gakhang, ngiyau bias, makuraccang, kenui floating and tipping at high levels, Sabung Hovering, reject slashing and splitting hui, able to bias, end to moderate level and end to low level, Lipetto and Jong Simpuh Sembah. Regarding the kinesthetic aspect of students dancing the Sigeh Penguten dance With the various movements mentioned above, starting from the first meeting to the seventh meeting, the eight students took practical tests to take scores and evaluations. The value obtained from the practical test carried out was an increase in understanding which could be seen in the increase in the value obtained, although it decreased slightly at the third meeting. The results of the VAk learning test (Visual, auditory., Kinesthetic) as a whole show the data that students have been able to demonstrate the Sigeh Penguten dance with an average score of Good.

The Turing Test

The relationship between AI and deception was initially explored by Alan Turing, who famously proposed in 1950 a practical test addressing the question “Can machines think?” This chapter argues that Turing’s proposal of the Imitation Game, now more commonly called the Turing test, located the prospects of AI not just in improvements of hardware and software but also in a more complex scenario emerging from the interaction between humans and computers. The Turing test, by placing humans at the center of its design as judges and as conversation agents alongside computers, created a space to imagine and experiment with AI technologies in terms of their credibility to human users. This entailed the discovery that AI was to be achieved not only through the development of more complex and functional computing technologies but also through the use of strategies and techniques exploiting humans’ liability to illusion and deception.

PROPOSAL OF MONITORING OF THE HEAT EXCHANGER STATION

The presented paper describes the creation of a “low-cost” monitoring security system based on the IoT platform connecting to the cloud. We focused on heat exchanger station, which is used in a block of flats. A simulation solution was devel-oped together with 3D visualization and a practical test. Final monitoring system informed the operator about the current state of the heat exchanger station and operator can intervene in time so that heat exchanger station is not suddenly damaged or cause some damage. Such monitoring system will find application in practice, but also in the teaching process, as the preparation of graduates for the modern monitoring systems, which are increasingly used in practice, will be improved. The presented paper is a scientific and methodological publication.
