The Bioterrorism Threat and Dual-use Biotechnological Research: An Israeli Perspective

Israel has a long history of concern with chemical and biological threats, since several hostile states in the Middle East are likely to possess such weapons. The Twin-Tower terrorist attacks and Anthrax envelope scares of 2001 were a watershed for public perceptions of the threat of unconventional terror in general and of biological terror in particular. New advances in biotechnology will only increase the ability of terrorists to exploit the burgeoning availability of related information to develop ever-more destructive bioweapons. Many areas of modern biological research are unavoidably dual-use by nature. They thus have a great potential for both help and harm; and facilitating the former while preventing the latter remains a serious challenge to researchers and governments alike. This article addresses how Israel might best (1) prevent hostile elements from obtaining, from Israel’s biological research system, materials, information and technologies that might facilitate their carrying out a biological attack, while (2) continuing to promote academic openness, excellence and other hallmarks of that system. This important and sensitive issue was assessed by a special national committee, and their recommendations are presented and discussed. One particularly innovative element is the restructuring and use of Israel’s extensive biosafety system to also address biosecurity goals, with minimal disruption or delay.     

Peer Group and Family Relationships in Early Adolescence

This study explored the possible interface between family and peer group systems in early adolescence. Sixth-graders who were identified as group members were interviewed and given questions regarding their attitudes toward the group and group dynamics. Family atmosphere and parent-adolescent relationships were evaluated from the parents' perspective. The results show two different linkages of peer and family processes: On the one hand, family relationships are related to the perception of the peer group as a source of support, especially when individual growth is respected within an atmosphere of acceptance and support in the family. On the other hand, family life characterized by conflict and lack of support for individual development is related to an increased involvement with groups and more conformity to group pressure. Results are discussed in line with theories dealing with the role of the family in adolescent development.     

Ducking the collection of costly evidence: Motivated use of statistical heuristics

We examined whether motivation affects people's use of statistical heuristics. In two studies, subjects had to decide how many instances to observe before making predictions. Half the subjects were led to believe that the observation of each instance would be relatively high in cost, and half were led to believe that it would be relatively low in cost. In both studies, only subjects for whom evidence collection was relatively high in cost accessed the aggregation principle and came to believe that aggregates afforded greater predictability than did single instances. Their belief that predictability increases sharply with sample size may have allowed these subjects to conclude what they wanted to conclude, namely that smaller samples would suffice for their predictions.     

Public and Private Values

In this paper, we experimentally examine whether looking at other people's pricing decisions is a type of a decision rule that people over‐apply even when it is not applicable, as in the case of private‐value goods. In Study 1, we find evidence that this is indeed the case—individual valuation of a subjective experience under full information, elicited using incentive compatible mechanism, is highly influenced by values of others. In Study 2, we find that people expect to use this rule to some degree with respect to actual consumption of goods, especially goods with some public value (music), and less so for private‐value goods (noise). However, people expect to use the rule to a very large extent when they are required to express their valuation of a good using a dollar figure (Study 3). These results can shed light on price behavior as rigidities and rents. Copyright © 2015 John Wiley & Sons, Ltd.     

The representation of time and location in memory for sentences

Two theoretical approaches to the representation of Time and Location Markers in Memory were contrasted. According to predictions derived from one approach, the amount of forgetting will be the same for two-proposition sentences and sentences with a single proposition and a Time or a Location marker. According to the other approach, the amount of forgetting will be the same for one-proposition sentences and sentences with a Time or a Location Marker. Propositional structure and the level of within-sentence associations were orthogonally varied to create eight within-subject experimental conditions. Ninety subjects studied 40 sentences and were required to recall then. Four dependent variables were used: number of sentences completely recalled, number of sentences partially recalled, number of sentences where information was lost from within the proposition, and number of sentences where a complete proposition was lost. The results suggest that Time and Location markers are represented in memory as arguments in a proposition rather than as separate propositions. Level of associations within the sentence seems to have a different effect when the sentence is composed of one or two propositions. The results also suggest that there may be differences between the representations of Time and Location markers.     

Self-Perception and Deceptive Behavior: The Uniqueness of Feminine Males

The present study investigated the relationshipbetween deception and selfperception of traditionallymasculine and feminine characteristics. In the firststage of the study, 730 fifth and sixth graders (377 boys and 353 girls), all Jewish Israelis,completed an adapted form of the BSRI (Bem, 1974). Inthe second stage of the study, 154 boys were given threetypes of questionnaires, one consisting of questions dealing with traditionally masculine topics,the second with traditionally feminine topics, and thethird with neutral topics. Since most of the questionswere very difficult, participants faced failure, but were given an opportunity to deceive andpretend to know more than they really did. It was found,as predicted, that cross-sex males, i.e., those whoself-endorse a large amount of traditionally feminine characteristics and a small amount oftraditionally masculine characteristics, were a uniquegroup. They were the only group who deceived more on thegender-inconsistent than gender-consistent task. The other gender role groups deceived more on thegender-consistent task than on the gender-inconsistenttask, or equally on both tasks. The results arediscussed within the context of the debate over themeaning of self-endorsement of masculine and femininetraits.     

The clenching-grinding spectrum and fear circuitry disorders: clinical insights from the neuroscience/paleoanthropology interface

This review discusses the clenching-grinding spectrum from the neuropsychiatric/neuroevolutionary perspective. In neuropsychiatry, signs of jaw clenching may be a useful objective marker for detecting or substantiating a self-report of current subjective emotional distress. Similarly, accelerated tooth wear may be an objective clinical sign for detecting, or substantiating, long-lasting anxiety. Clenching-grinding behaviors affect at least 8 percent of the population. We argue that during the early paleolithic environment of evolutionary adaptedness, jaw clenching was an adaptive trait because it rapidly strengthened the masseter and temporalis muscles, enabling a stronger, deeper and therefore more lethal bite in expectation of conflict (warfare) with conspecifics. Similarly, sharper incisors produced by teeth grinding may have served as weaponry during early human combat. We posit that alleles predisposing to fear-induced clenching-grinding were evolutionarily conserved in the human clade (lineage) since they remained adaptive for anatomically and mitochondrially modern humans (Homo sapiens) well into the mid-paleolithic. Clenching-grinding, sleep bruxism, myofacial pain, craniomaxillofacial musculoskeletal pain, temporomandibular disorders, oro-facial pain, and the fibromyalgia/chronic fatigue spectrum disorders are linked. A 2003 Cochrane meta-analysis concluded that dental procedures for the above spectrum disorders are not evidence based. There is a need for early detection of clenching-grinding in anxiety disorder clinics and for research into science-based interventions. Finally, research needs to examine the possible utility of incorporating physical signs into Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition posttraumatic stress disorder diagnostic criteria. One of the diagnostic criterion that may need to undergo a revision in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition is Criterion D (persistent fear-circuitry activation not present before the trauma). Grinding-induced incisor wear, and clenching-induced palpable masseter tenderness may be examples of such objective physical signs of persistent fear-circuitry activation (posttraumatic stress disorder Criterion D).     

High‐conflict divorced couples: combining systemic and psychodynamic perspectives

This article describes typologies of couples in high‐conflict divorces and explores their dynamics through the prism of family systems and British object relations theories. The article argues that couples embroiled in high‐conflict divorce often have primitive object relations. They tend to use splitting and projection processes and find it difficult to tolerate ambivalence or disagreement. Fear of the ex‐spouse's retaliation is often accompanied by fear of their own destructiveness and by a wish to make reparation. However, it seems that reparation attempts in primitive object relations rarely achieve reconciliation. A case study demonstrates the complicated dynamics of these couples. Clinical recommendations are made.
