INTRODUCTION: Mentalization can be an important tool to tackle the effects on mental health due to COVID-19 lockdown measures. OBJECTIVES: The main objective of this study was to evaluate mentalization, loneliness, internalizing problems and subjective experience during COVID-19 quarantine. Specific objectives included the study of a) temporal evolution of mentalization, loneliness and internalizing symptoms b) effects of loneliness and mentalization on anxiety/depression and somatic complaints and c) moderation effects of mentalization on loneliness. METHODOLOGY: This was part of a three-phase, cross sectional, longitudinal qualitative/quantitative design study, with an intentional, non-probabilistic sample. MentS, Three-Item-loneliness Scale and Adult self-report were used to measure mentalization, loneliness, internalizing symptoms and somatic complaints, respectively. RESULTS: Feelings of loneliness, anxiety/depressive symptoms and somatic complaints increased over time. Significant variations of loneliness on depression, anxiety and somatic complaints were observed, and it’s higher level was linked with higher presence of symptoms. Mentalization experienced no significant change, and a higher level of it was associated with lower symptomatology and marginally significant moderation effects over loneliness. DISCUSSION AND LIMITATIONS: A mentalization based intervention should be proposed to mitigate the effects of loneliness on internalizing symptoms. The sample was not representative of the population.

Next generation assembly/package development challenges are primarily increased interconnect complexity, density, and multi-layer/multi-stacked packages with ever shorter development time. The results of this trend present some distinct challenges for the analytical tools and techniques to support this technology roadmap. The key challenge in the analytical tools and techniques is the development of nondestructive imaging for improved time to information. The 3D X-ray Computed tomography (CT) system named “X-Tek NGI” has been co-developed by Intel and X-Tek to address this need. The current paper will discuss the configuration and several applications where this tool has been applied successfully to solve current package technology development issues and provide package construction analysis (including enabled components). This paper will discuss the details of the system configuration, examples together with the current limitations and future direction for non-destructive package failure analysis.

The rationale for the following unsystematic review article is to provide a dense description of clapping behavior from an ethological, psychological, anthropological, sociological, ontological, and even physiological perspective. The article delves into its historical uses, possible biological-ethological evolution, and primitive and cultural polysemic-multipurpose social functions. It explores the different distal and immediate messages transmitted by the simple act of clapping, to its more complex attributes like synchronicity, social contagion, as a device of social status signaling, soft biometric data, and its, till now, mysterious subjective experience. The subtle distinction between clapping and applause will be explored. A list of primary social functions will be introduced based on the literature on clapping. In addition, a series of unresolved questions and possible research avenues will be suggested. In contrast, out of the scope of the essay and published as a second article will be the contents of clapping morphological variations and a comprehensive description of purposes achieved through them.
