Shahar\u27s Producing Capstone

The series of videos below were all produced between Sep-Nov 2019. They were part of 219 West, a news magazine TV show, airing on CUNY-TV and produced by the graduate students at the Craig Newmark School of Journalism. While the videos might not have an obvious common thread, I saw them all as attempts to show New Yorkers who were challanging societal norms by centering their hobbies in life while surviving in the big apple. The stories show a soccer player, a visual artists, and a skater, that either for pleasure, or to make a living, spend much of their week pursuing their passions. But, their stories are by no means cliche success stories of following your dreams. At best, they are a minor victory against the 9–5 life.

A Lion’s Blues: Heroism, Heroic Self-Representations, and Emotional Distress in the Life and Character of Yonatan (Yoni) Netanyahu

The realization that heroism – representing either a trait or a value system – is potentially pernicious is important for both scientific and societal reasons. In this article, we adopt a psychobiographical perspective to analyze the character and life of one of Israel’s greatest heroes, Yonathan (“Yoni”) Netanyahu. Yoni was an illustrious military leader, as well as an outstanding intellectual and adored persona. He served as the commander of the special operation forces spearheading the famous Entebbe Operation during which Israeli commando forces rescued hostages taken captive in Uganda. Yoni was the only military causality in this operation, which was ultimately named after him. Subsequent to his death, his numerous personal letters were made public, allowing further glimpses into his heroic self-representations but also to the emotional distress he suffered. Applying our theory of heroic self-representations (HERS; Shahar, 2013), we analyze Yoni\u27s letters. Our analyses confirm Yoni\u27s tendency to construe himself as a savior and conqueror, and to identify with cultural heroes. The emotional distress Yoni suffered is characterized by depressed and anxious affect, masked by superb functioning. Qualitative analyses of the letters suggest two mechanisms of the effect of heroic self-representations on distress in Yoni\u27s case: compulsive purposefulness and emotional seclusion

Budget-Constrained Item Cold-Start Handling in Collaborative Filtering Recommenders via Optimal Design

It is well known that collaborative filtering (CF) based recommender systems provide better modeling of users and items associated with considerable rating history. The lack of historical ratings results in the user and the item cold-start problems. The latter is the main focus of this work. Most of the current literature addresses this problem by integrating content-based recommendation techniques to model the new item. However, in many cases such content is not available, and the question arises is whether this problem can be mitigated using CF techniques only. We formalize this problem as an optimization problem: given a new item, a pool of available users, and a budget constraint, select which users to assign with the task of rating the new item in order to minimize the prediction error of our model. We show that the objective function is monotone-supermodular, and propose efficient optimal design based algorithms that attain an approximation to its optimum. Our findings are verified by an empirical study using the Netflix dataset, where the proposed algorithms outperform several baselines for the problem at hand.Comment: 11 pages, 2 figure

A Linear Molecule with Two Large Inverted Repeats: The Mitochondrial Genome of the Stramenopile Proteromonas lacertae

Mitochondrial evolution has given rise to a complex array of organelles, ranging from classical aerobic mitochondria to mitochondrial remnants known as hydrogenosomes and mitosomes. The latter are found in anaerobic eukaryotes, and these highly derived organelles often retain only scant evidence of their mitochondrial origins. Intermediate evolutionary stages have also been reported as facultatively or even strictly anaerobic mitochondria, and hydrogenosomes that still retain some mitochondrial features. However, the diversity among these organelles with transitional features remains rather unclear and barely studied. Here, we report the sequence, structure, and gene content of the mitochondrial DNA of the anaerobic stramenopile Proteromonas lacertae. It has a linear genome with a unique central region flanked by two identical large inverted repeats containing numerous genes and “telomeres” with short inverted repeats. Comparison with the organelle genome of the strictly anaerobic human parasite Blastocystis reveals that, despite the close similarity of the sequences, features such as the genome structure display striking differences. It remains unclear whether the virtually identical gene repertoires are the result of convergence or descent

The Interplay Between Childhood Sexual Abuse, Self-Concept Clarity, and Dissociation: A Resilience-Based Perspective

BACKGROUND: Despite a robust consensus regarding the potentially negative implications of childhood sexual abuse (CSA), research investigating risk and protective factors-particularly among well-functioning young adults-is scant. Dissociation is one of the major maladaptive outcomes of CSA. Nevertheless, CSA explains only about 10% of the variance of dissociation. Possibly, this modest effect size is due to protective factors moderating the relation between CSA and dissociative symptoms. One such factor may be the extent to which one has succeeded in developing a clear and coherent sense of who they are. OBJECTIVE: We aimed to explore whether self-concept clarity (SCC) moderates the relationship between CSA and dissociation (Model 1), and an alternative hypothesis, whereby CSA may moderate the relationship between SCC and dissociation (Model 2). PARTICIPANTS AND SETTING: This was tested among 65 well-functioning young women drawn from an earlier study that intentionally oversampled CSA survivors. METHODS: We included data from survivors of CSA by a known perpetrator (n = 35) and women with no sexual trauma (n = 30). RESULTS: Findings were consistent with both Model 1 and Model 2, but only when depersonalization-derealization, namely detachment, was considered. Simple effects analyses revealed that CSA was related to depersonalization-derealization only under low SCC levels (Model 1), and SCC was negatively related to depersonalization-derealization only in the CSA group (Model 2). CONCLUSIONS: Findings suggest that SCC is a protective factor, buffering the association between CSA and detachment (depersonalization-derealization) symptoms. Clinical implications are discussed

The Four-Cluster Spectrum of Mind-Body Interrelationships: An Integrative Model

Despite the shift toward a biopsychosocial paradigm of medicine, many physicians and mental health professionals (MHPs) find it difficult to treat patients with psycho-somatic disorders. This situation is particularly troublesome due to the high prevalence of these conditions. Although progress has been made over the last few decades in understanding mechanisms underlying the mind-body relationship, disparities remain between research and its clinical implementation. One possible reason for this is the lack of a comprehensive, agreed-upon model that incorporates a biopsychosocial framework and is rooted in an understanding of the various psychobiological pathways. Such a model would enable better communication between physicians and MHPs, allowing them to provide coordinated, stratified treatment. In this paper, four archetypal case studies, together with standard care options are presented to illustrate the current state of affairs. A four-tiered conceptual model of mind-body interrelationships based on pathophysiological and psychopathological mechanisms is suggested to help optimize the treatment of somatic complaints. This Four-Cluster model consists of: (1) Organic Conditions: Structural, or degenerative processes that can affect mood and psychological responses but are not clearly exacerbated by stress. (2) Stress Exacerbated Diseases: Biological disorders with a distinct pathophysiology, such as inflammatory or autoimmune diseases, whose progression is clearly exacerbated by stress. (3) Functional Somatic Syndromes: Conditions wherein heightened sensitivity to stimuli together with hyper-reactivity of the autonomic system form a “vicious cycle” of mutually enhancing learning processes. These processes involve biological mechanisms, such as central sensitization and psychological mechanisms such as catastrophization and selective attention. (4) Conversion Disorder: Physical manifestations of psychological distress, expressed somatically. Symptoms are solely an expression of problems in patients' psychic functioning and are not caused by biological pathology. Finally, suggested management of the aforementioned case studies is presented through the lens of the Four-Cluster model and a proposed integration of our model with existing theories is discussed. As it is rooted in an understanding of psychobiological pathways of illness, the proposed model enables a new way to discern which form of mind-body interaction is manifesting in different diseases and proposes a way to coordinate treatment plans accordingly, to enhance the accuracy and efficacy of care

Basic and complex emotion recognition in children with autism: cross-cultural findings.

BACKGROUND: Children with autism spectrum conditions (ASC) have emotion recognition deficits when tested in different expression modalities (face, voice, body). However, these findings usually focus on basic emotions, using one or two expression modalities. In addition, cultural similarities and differences in emotion recognition patterns in children with ASC have not been explored before. The current study examined the similarities and differences in the recognition of basic and complex emotions by children with ASC and typically developing (TD) controls across three cultures: Israel, Britain, and Sweden. METHODS: Fifty-five children with high-functioning ASC, aged 5-9, were compared to 58 TD children. On each site, groups were matched on age, sex, and IQ. Children were tested using four tasks, examining recognition of basic and complex emotions from voice recordings, videos of facial and bodily expressions, and emotional video scenarios including all modalities in context. RESULTS: Compared to their TD peers, children with ASC showed emotion recognition deficits in both basic and complex emotions on all three modalities and their integration in context. Complex emotions were harder to recognize, compared to basic emotions for the entire sample. Cross-cultural agreement was found for all major findings, with minor deviations on the face and body tasks. CONCLUSIONS: Our findings highlight the multimodal nature of ER deficits in ASC, which exist for basic as well as complex emotions and are relatively stable cross-culturally. Cross-cultural research has the potential to reveal both autism-specific universal deficits and the role that specific cultures play in the way empathy operates in different countries.The research leading to this work has received funding from the European Community’s Seventh Framework Programme (FP7) under grant agreement no.

Multiple emergences of genetically diverse amphibian-infecting chytrids include a globalized hypervirulent recombinant lineage

Batrachochytriumdendrobatidis (Bd) is a globally ubiquitous fungal infection that has emerged to become a primary driver of amphibian biodiversity loss. Despite widespread effort to understand the emergence of this panzootic, the origins of the infection, its patterns of global spread, and principle mode of evolution remain largely unknown. Using comparative population genomics, we discovered three deeply diverged lineages of Bd associated with amphibians. Two of these lineages were found in multiple continents and are associated with known introductions by the amphibian trade.We found that isolates belonging to one clade, the global panzootic lineage (BdGPL) have emerged across at least five continents during the 20th century and are associated with the onset of epizootics in North America, Central America, the Caribbean, Australia, and Europe. The two newly identified divergent lineages, Cape lineage (BdCAPE) and Swiss lineage (BdCH), were found to differ in morphological traits when compared against one another and BdGPL, and we show that BdGPL is hypervirulent. BdGPL uniquely bears the hallmarks of genomic recombination, manifested as extensive intergenomic phylogenetic conflict and patchily distributed heterozygosity. Wepostulate that contact between previously genetically isolated allopatric populations of Bd may have allowed recombination to occur, resulting in the generation, spread, and invasion of the hypervirulent BdGPL leading to contemporary disease-driven losses in amphibian biodiversity.Peer Reviewe
