The function of Early Natufian grooved basalt artefacts from el-Wad Terrace, Mount Carmel, Israel: Preliminary results of a use-wear analysis

[Report]Grooved items are usually regarded as tools used for modifying other implements made of bone, stone, plants or wood, whether referred to as shaft straighteners, smoothers, polishers or sharpening tools. They were also attributed to various symbolic meanings in Neolithic and Chalcolithic sites in the southern Levant and they were also associated with bead manufacturing process in the Neolithic. Grooved basalts found on Early Natufian (ca. 14,000 BP) living floors at el-Wad Terrace, Mount Carmel, Israel, were the subject of microscopic use-wear analysis. Here we present the preliminary results of the research, introducing our functional reconstruction based on experiments. The most outstanding result is that traces on the perimeters, attributed to shaping of the artefact, are different from the traces inside the groove which are related to the use of the artefact. We conclude that the groove is a part of the instrument, shaped before its use in order to work the abraded materials. Traces indicate that the shaping of the perimeters was done by abrasion against a very hard rock, probably using water to enhance the smoothing of the stone. Traces inside the groove indicate, as was previously assumed for these artefacts, that the groove was used as a shaft straightener. However, traces also indicate that the groove was used to abrade different types of materials which might not be related to the preparation of shafts including reeds, wood, and especially minerals such as ochre. Our preliminary results indicate the multi-functional nature of these items shedding light on their production, use and discard history

"Transport Me Away": Fostering Flow in Open Offices through Virtual Reality

Open offices are cost-effective and continue to be popular. However, research shows that these environments, brimming with distractions and sensory overload, frequently hamper productivity. Our research investigates the use of virtual reality (VR) to mitigate distractions in an open office setting and improve one’s ability to be in flow. In a lab study, 35 participants performed visual programming tasks in four combinations of physical (open or closed office) and virtual environments(beach or virtual office). While participants both preferred and were in flow more in a closed office without VR, in an open office, the VR environments outperformed the no VR condition in all measures of flow, performance, and preference. Especially considering the recent rapid advancements in VR, our findings illustrate the potential VR has to improve flow and satisfaction in open offices
