AbstractThis study focuses on the Neolithic, particularly on the emergence and development of the Diana Culture in the Aeolian Islands. Since the 1950s, the archaeological excavations unearthed parts of a settlement in a plain near the sea, contrada Diana in Lipari. We discuss the technological and typometric study of obsidian from trenches XVII, XXI, and XXXVI. A series of pXRF analyses on obsidian were carried out to identify their sources. A selection of retouched and non-retouched artifacts was examined, showing the higher variability in forms than at importing sites. This significance of this workshop area on prehistoric trade is assessed.

Social media and content-sharing platforms provide new opportunities for the circulation of not only professional and amateur porn productions but also “pornographic self-representation”. This study examines the interactions that occur when male pornographic self-representation is shared in an inclusive space that welcomes both straight and gay men to post dick pics and gaze/comment on them. Focusing on the Reddit forum, Massive Cock, we conducted a discourse analysis of a selection of posts, comments and account profiles collected over a seven-month period. Based on our findings, we contend that Massive is a homosocial space where homoerotic dick gazing reaffirms and disrupts the heterosexual–homosexual binary. Our findings point to an uneven dynamic in which the majority of the posters perform a straight identity, whereas the majority of commenters perform a gay identity. Their comments serve to disrupt hegemonic masculinity and, in turn, create a space that welcomes mostly straight and bi-curious performances of masculinity. Such performances are possible due to recent cultural shift away from homo-hysteria and towards a more inclusive heteromasculinity. Collectively these performances produce an inclusive “fraternity of the cock”, but it is one which maintains a heterocentric focus and function.

Abstract The paper presents the results obtained by techno-typological analysis of a lithic assemblage from the Neolithic layers of Grotta San Michele Arcangelo di Saracena (Cosenza) together with the results of micro-wear analysis obtained from a preliminary selection of obsidian artifacts with different provenances distinguished by pXRF analysis. The site provides one of the best preserved Neolithic sequences in the area, from the earliest Impressed Wares (or Impresse Arcaiche) (early sixth millennium BC) to the Spatarella pottery style (end fifth – early fourth millennium BC). Along the Neolithic sequence, it is possible to observe some major changes within lithic resources management. In particular, it is possible to notice some techno-typological breakages between the Early Neolithic and the further stages, until the second phase of the Late Neolithic, when another rupture, corresponding to the Spatarella facies, is evident.

Culinary is one of the favorite businesses today. The number of considerations to choose a restaurant or place to visit becomes one of the factors that is difficult to determine the restaurant or place to eat. To get the desired place to eat advice, one needs a recommendation system. Decisions made by the recommendation system can be used as a reference to determine the choice of restaurants. One method that can be used to build a recommendation system is Case Based Reasoning. The Case Based Reasoning (CBR) method mimics human ability to solve a problem or cases. The retrieval process is the most important stage, because at this stage the search for a solution for a new case is carried out. The study used the K-Nearest Neighbor method to find closeness between new cases and case bases. With the selection of features used as domains in the system, the results of recommendations presented can be more suggestive and accurate. The system successfully provides complex recommendations based on the type and type of food entered by the user. Based on blackbox testing, the system has features that can be used and function properly according to the purpose of creating the system.

Abstract From 2009 to 2012, a joint research team of Japanese and Vietnamese archaeologists led by the late Prof. Nishimura Masanari conducted surveys and excavations at fifteen sites around the Hoa Chau Citadel in Thua Thien Hue Province, built by the Champa people in the ninth century and used by the Viet people until the fifteenth century. This article introduces some findings from recent archaeological excavations undertaken at three Champa citadels: the Hoa Chau Citadel, the Tra Kieu Citadel in Quang Nam Province, and the Cha Ban Citadel in Binh Dinh Province. Combined with historical material and field surveys, the paper describes the scope and structure of the ancient citadels of Champa, and it explores the position, role, and function of these citadels in the context of their own nagaras (small kingdoms) and of mandala Champa as a whole. Through comparative analysis, an attempt is made to identify features characteristic of ancient Champa citadels in general.

There is a general consensus that substantial heterogeneity underlies the neurobiology in autism spectrum disorder (ASD). As such, it has become increasingly clear that a dissection of variation at the molecular-, cellular-, and system-level domains is a prerequisite for identifying biomarkers and developing more targeted therapeutic strategies in ASD. Advances in neuroimaging approaches to characterizing atypical brain patterns have recently motivated their application as viable tools to delineate more homogenous ASD subgroups at the level of brain structure and function - i.e., neurosubtyping. This review assesses and critically discusses the current data-driven neurosubtyping in ASD. It breaks this pursuit into key methodological steps: the selection of diagnostic samples, neuroimaging features, algorithm and validation approaches. For each step, we appraise the current literature in terms of progress, as well as remaining challenges and potential solutions. Convergence across findings is discussed and biological implications are highlighted. Although preliminary and with limited methodological overlap, results from this literature illustrate the feasibility of neurosubtyping. Across studies, there is general agreement that distinct neurosubtypes exist, but the exact number and their definitions vary depending on the specific features and approach utilized in a given study. Results also suggest the utility of subtypes in predicting symptom severity and diagnostic labels above and beyond group-average comparison designs. This review concludes with a discussion of future avenues towards a comprehensive understanding of the mechanisms underlying ASD heterogeneity.

In the past fifteen years we have substantially improved our knowledge of the seafaring expeditions in the Mediterranean, based either on the indirect evidence of the navigation or on what we know about the earliest such ventures. This paper presents an overview of what is known about the earliest navigation in the Mediterranean and considers the origin of the first such ventures in the Adriatic as a specific part of the Mediterranean. It focuses on the problem of the navigation between the Italic and Croatian coasts, tackling the possibility of such maritime expeditions based on the distribution of the obsidian from the Aeolian Islands. It also ponders on the practical aspects of the use of sailing vessels in the Late Neolithic.

The 16th Meeting of the Interuniversity Institute of Myology (IIM), October 17-20, 2019, Assisi, Italy brought together scientists, pharma and patient organization representatives discussing new results on muscle research. Internationally renowned Keynote speakers presented advances on muscle development, homeostasis, metabolism, and disease. Speakers selected among submitted abstracts presented their new, unpublished data in seven scientific sessions. The remaining abstracts were showcased in two poster sessions. Young trainees where directly involved in the selection of keynote speakers, the organizing scientific sessions and roundtables discussions tailored to the interests of their peers. A broad Italian, European and North-American audience participated to the different initiatives. The meeting allowed muscle biology researchers to discuss ideas and scientific collaborations aimed at better understanding the mechanisms underlaying muscle diseases in order to develop better therapeutic strategies. The active participation of young trainees was facilitated by the friendly and inclusive atmosphere, which fostered lively discussions identifying emerging areas of myology research and stimulated scientific cross-fertilization. The meeting was a success and the IIM community will continue to bring forward significant contributions to the understanding of muscle development and function, the pathogenesis of muscular diseases and the development of novel therapeutic approaches. Here, we report abstracts of the meeting illustrating novel results of basic, translational, and clinical research, which confirms that the Myology field is strong and healthy.

Linker histones are multifunctional proteins that are involved in a myriad of processes ranging from stabilizing the folding and condensation of chromatin to playing a direct role in regulating gene expression. However, how this class of enigmatic proteins binds in chromatin and accomplishes these functions remains unclear. Here we review data regarding the H1 structure and function in chromatin, with special emphasis on the C-terminal domain (CTD), which typically encompasses approximately half of the mass of the linker histone and includes a large excess of positively charged residues. Owing to its amino acid composition, the CTD was previously proposed to function in chromatin as an unstructured polycation. However, structural studies have shown that the CTD adopts detectable secondary structure when interacting with DNA and macromolecular crowding agents. We describe classic and recent experiments defining the function of this domain in chromatin folding and emerging data indicating that the function of this protein may be linked to intrinsic disorder.
