How does Socio-Political Context Shape Daily Living: The Case of Jews and Arabs in Israel  [PDF]
Adital Ben-Ari, Yoav Lavee
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.21001
Abstract: The present paper addresses a timely topic by exploring the contribution of cultural, ethnic, and contextual attributes to close relationships within particular armed-political conflict. It is based on a series of studies to examine the daily lives of Jews and Arabs with different cultural orientations within the context of armed political conflict. In Study 1, we surveyed 697 Jewish and 300 Arab respondents to examine the extent to which daily occurrences are similarly experienced as stressful by different cultural and socio-political groups and how those occurrences relate to life and marital satisfaction. In Study 2, we employed a daily diary methodology with a sample of 300 couples to explore how daily fluctuations in psychological well-being and marital relationships relate to daily hassles. Security-related stress was perceived as the main source of stress for both Jews and Arabs, but on a daily basis it had little or no effect on well-being and marital relationships. The findings attest to the significance of the socio-political context within which people of different ethnic and cultural identity experience their daily lives. In so doing, this article advances new directions for theory and research.
Dialectics between Splitting and Integrating in the Lives of Heterosexually Married Gay Men  [PDF]
Adital Ben-Ari, Adir Adler
Psychology (PSYCH) , 2010, DOI: 10.4236/psych.2010.12014
Abstract: Mixed-orientation marriage is usually an invisible phenomenon, but its frequency is not insignificant. The present paper describes and examines the experiences of 13 heterosexually married gay men, seven of whose wives were aware and six who were unaware of their husbands’ homosexuality. We take the insiders’ perspective as a point of departure to develop a conceptual model that may contribute to our understanding of the constructed reality of this relatively unexplored phenomenon. The findings show that life in a mixed-orientation marriage can be understood along a continuum running between two poles: splitting and integrating. This continuum corresponds to the fundamental question in the lives of heterosexually married gay men: Is integration between homosexuality and heterosexual marriage possible, and if so, how?
The Transcervical Approach for Parapharyngeal Space Pleomorphic Adenomas: Indications and Technique
Gilad Horowitz, Oded Ben-Ari, Oshri Wasserzug, Noam Weizman, Moshe Yehuda, Dan M. Fliss
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0090210
Abstract: Background Head and Neck Parapharyngeal space tumors are rare. Pleomorphic Adenomas are the most common Parapharyngeal space tumors. The purpose of this study was to define preoperative criteria for enabling full extirpation of parapharyngeal space pleomorphic adenomas via the transcervical approach while minimizing functional and cosmetic morbidity. Methods The surgical records and medical charts of 19 females and 10 males with parapharyngeal space pleomorphic adenomas operated between 1993 and 2012 were reviewed. Results Fifteen patients were operated by a simple transcervical approach, 13 by a transparotid transcervical approach, and one by a transmandibular transcervical approach. Complications included facial nerve paralysis, infection, hemorrhage and first bite syndrome. There were three recurrences, but neither recurrence nor complications were associated with the type of surgical approach. Conclusion A simple transcervical approach is preferred for parapharyngeal space pleomorphic adenomas with narrow attachments to the deep lobe of the parotid gland and for pleomorphic adenomas originating in a minor salivary gland within the parapharyngeal space.

La ā’if, Paraenetica and Prophets: restudying Junta Manuscript Kitāb la ā’if al-Anbiy’ wa-fhi Qi a al-Anbiyā’
Ben-Ari, Shosh
Al-Qantara : Revista de Estudios Arabes , 2008,
Abstract: While examining the genre of “The Stories of the Prophets” (Qi a al-Anbiyā’) as background to my dissertation about Abraham in Islamic literature, I received from Prof. J. Sadan a manuscript that he found in the British Library that is related to this genre. Later I found similar versions of the same composition, which led me to try to find how this compilation emerged. The composition is very close to the preaching literature (wa‘ ), which deals mainly with moral education, but it also includes stories. I wondered if this is a literary genre, standing by itself, which started out as an aid, auxiliary material for understanding the oral tradition and religious studies, and then became an independent genre, closer to edifying literature, known as Paraenetica, or to the genre of Specula Regis (Mirrors of kings). I describe the manuscript in order to try to reach a conclusion: is this a different literary genre? Is it an educational genre or only a simplified version of stories for a child or a non-Arab ruler whose education was in Arabic language? Or did the writer perhaps want an original name for his compilation, and as the name Qi a al-Anbiyā’ was already in use he chose a different name, using a word which also intimates the collection’s small size? Trabajando sobre el género de “Historias de los Profetas” (Qi a al-Anbiyā’) en el proceso de elaboración de mi tesis sobre Abraham en la literatura islámica, el profesor J. Sadan me envió un manuscrito que había localizado en la British Library relacionado con este género. Posteriormente encontré versiones similares de la misma composición, lo que me animó a profundizar mi investigación sobre sus orígenes. La obra está próxima a la literatura de predicación (wa‘ ), que se ocupa principalmente de la educación moral, pero también incluye historias. Me planteé la posibilidad de que éste formarse un género que hubiera surgido como una ayuda, un material auxiliar concebido para entender la tradición oral y los estudios religiosos para, posteriormente, convertirse en un género independiente, más cercano a la Parénesis o al Specula Regis (Espejos de príncipes). Describiré el manuscrito para intentar alcanzar una conclusión sobre ciertas cuestiones: es éste un género literario diferente?, se trata de un género educativo o solamente es una versión simplificada de historias para ilustrar a ni os o principiantes de la lengua árabe?, buscaría el autor un nombre original para su compilación, haciendo referencia al reducido tama o de la colección y descartando el de Qi a al-Anbiyā’ por ser conocido?
FACING CHILD SOLDIERS, MORAL ISSUES, AND “REAL SOLDIERING”: ANTHROPOLOGICAL PERSPECTIVES ON PROFESSIONAL ARMED FORCES*
Eyal Ben-Ari
Scientia Militaria : South African Journal of Military Studies , 2011, DOI: 10.5787/37-1-57
Abstract: In today’s world, adolescents and children sometimes act as combatants who directly participate in hostilities. Yet more often they are deployed as auxiliaries (for example, as lookouts or messengers) or in various support roles (as gardening, road maintenance, delivery of food, cleaning, cooking, conveying goods and providing sexual services) (Boothby and Knudsen 2000). Finally, under certain circumstances, adolescents and children may be used as human shields or for propaganda purposes by government or opposition forces (Boyden and De Berry 2004:xii; United Nations 2002:13). Since the late 1970s, a number of international conventions have been promulgated to limit the use of these young people, but children continue to be deployed in parts of the world and overwhelmingly in sub-Saharan Africa. Estimates as to their numbers vary. Human Rights Watch (2007), a human rights lobby, estimates that there are between 200 000 and 300 000 such youngsters in armed conflicts in over twenty countries.

Phenobarbital but Not Diazepam Reduces AMPA/kainate Receptor Mediated Currents and Exerts Opposite Actions on Initial Seizures in the Neonatal Rat Hippocampus
Yehezkel Ben-Ari
Frontiers in Cellular Neuroscience , 2011, DOI: 10.3389/fncel.2011.00016
Abstract: Diazepam (DZP) and phenobarbital (PB) are extensively used as first and second line drugs to treat acute seizures in neonates and their actions are thought to be mediated by increasing the actions of GABAergic signals. Yet, their efficacy is variable with occasional failure or even aggravation of recurrent seizures questioning whether other mechanisms are not involved in their actions. We have now compared the effects of DZP and PB on ictal-like events (ILEs) in an in vitro model of mirror focus (MF). Using the three-compartment chamber with the two immature hippocampi and their commissural fibers placed in three different compartments, kainate was applied to one hippocampus and PB or DZP to the contralateral one, either after one ILE, or after many recurrent ILEs that produce an epileptogenic MF. We report that in contrast to PB, DZP aggravated propagating ILEs from the start, and did not prevent the formation of MF. PB reduced and DZP increased the network driven giant depolarizing potentials suggesting that PB may exert additional actions that are not mediated by GABA signaling. In keeping with this, PB but not DZP reduced field potentials recorded in the presence of GABA and NMDA receptor antagonists. These effects are mediated by a direct action on AMPA/kainate receptors since PB: (i) reduced AMPA/kainate receptor mediated currents induced by focal applications of glutamate; (ii) reduced the amplitude and the frequency of AMPA but not NMDA receptor mediated miniature excitatory postsynaptic currents (EPSCs); (iii) augmented the number of AMPA receptor mediated EPSCs failures evoked by minimal stimulation. These effects persisted in MF. Therefore, PB exerts its anticonvulsive actions partly by reducing AMPA/kainate receptors mediated EPSCs in addition to the pro-GABA effects. We suggest that PB may have advantage over DZP in the treatment of initial neonatal seizures since the additional reduction of glutamate receptors mediated signals may reduce the severity of neonatal seizures.
Principal Eigenvalue for Brownian Motion on a Bounded Interval with Degenerate Instantaneous Jumps
Iddo Ben-Ari
Mathematics , 2012,
Abstract: We consider a model of Brownian motion on a bounded open interval with instantaneous jumps. The jumps occur at a spatially dependent rate given by a positive parameter times a continuous function positive on the interval and vanishing on its boundary. At each jump event the process is redistributed uniformly in the interval. We obtain sharp asymptotic bounds on the principal eigenvalue for the generator of the process as the parameter tends to infinity. Our work answers a question posed by Arcusin and Pinsky.
Geodesics in a Graph of Perfect Matchings
Roy Ben-Ari
Mathematics , 2013,
Abstract: This paper studies geodesics in the graph $\mathscr{P}_{m}$, which has all perfect matchings in $K_{2m}$ as vertices with two perfect matchings connected by an edge if their symmetric difference is a cycle of length four. The diameter of $\mathscr{P}_{m}$, as well as the eccentricity of each vertex, are shown to be $m-1$. The number of geodesics between any two antipodes is shown to be $m^{m-2}$ and an explicit formula for the number of geodesics between any two matchings in $\mathscr{P}_{m}$ is given. The paper concludes by showing that the subgraph of non-crossing perfect matchings has exactly one pair of antipodes having the maximal number ($m^{m-2}$) of geodesics.
