Lower Cancer Rates Among Druze Compared to Arab and Jewish Populations in Israel, 1999–2009

The Druze are a small ethnic minority in Israel amounting to about 130,000 residents (or 1.7 % of the total population of the country). Unlike other population groups, the Druze strive to keep their own traditions and marry mainly inside their own community. During the last decade, cancer morbidity among both Jews and Arabs in Israel has been increasing, while data on the Druze are little known and have not been analyzed and compared to other population groups to date. To compare cancer morbidity rates among Druze, Arabs and Jews in Israel during 1999–2009, gender-specific and age-standardized incidence rates of all site cancers and specific cancers of three population groups (Jews, Arabs and Druze) were received from the Israel National Cancer Registry for the period 1999–2009. Based on these rates, periodical incidence rates were calculated and mutually compared across the groups stratified by gender. As the analysis shows, the Druze had significantly lower cancer rates compared to both Arabs and Jews. Thus, for all site cancers, there were significantly higher cancer rates in Jewish males versus Druze males (RR = 1.39, 95 % CI = 1.16–1.65) and in Jewish females versus Druze females (RR = 1.53, 95 % CI = 1.27–1.85), but not statistically significant for Arab males versus Druze males (RR = 1.12 95 % CI = 0.93–1.35). Lung cancer rates in Arab males were also higher compared to Druze males (RR = 1.84, 95 % CI = 1.13–3.00). Jewish males had statistically significant higher rates of prostate cancer compared to Druze males (RR = 2.47, 95 % CI = 1.55–3.91). For thyroid and colon cancers, risks were not significantly different at the 95 % CI level; however, the risks were significantly different at the 90 % CI level (RR = 3.62, 90 % CI 1.20–11.02 and RR = 1.69, 90 % CI = 1.03–2.77, respectively). Jewish females had significantly higher rates of invasive breast cancer (RR = 2.25, 95 % CI = 1.55–3.25), in situ cervical cancer (RR = 4.01, 95 % CI = 1.27–12.66) and lung cancer (RR = 3.22, 95 % CI = 1.12–9.24) compared to Druze females. We thus observed lower cancer rates among Druze versus Arab and Jewish populations in Israel. A reason for these differences may be due to different nutritional habits. Druze still keep a less processed nutritional lifestyle, than is common in industrial society. There may also be other reasons that have not been identified yet.     

Who is the Addressee of Philosophical Argumentation?

Chaim Perelman invokes the idea of “universal audience” for explaining the nature of philosophical argumentation as rational rhetoric. As opposed to this view, centuries before Perelman, Socrates argues that philosophy should be conducted as a dialogue between concrete individuals with very specific qualities. The paper presents these different views in order to claim that the philosopher addresses neither a universal audience nor a particular other, but mainly and essentially the philosopher herself/himself. This brings to light the problem of self-deception as a central problem of philosophical thinking. In posing this view the paper uses Nietzsche’s definition of “the will to truth” as the will not to deceive, not even myself.

Multi-attribute choice and affect: The influence of naturally occurring and manipulated moods on choice processes

Based on a two-dimensional model of affect that views Pleasantness and Arousal as affect's two primary dimensions, this study investigates the effects of emotions on choice processes and outcomes. In Study 1, subjects first described their naturally occurring emotional state and then performed two multi-attribute product choice tasks. Subjects in more pleasant mood deliberated longer, used more decision-related information, re-examined more previously examined information, and made more interdimensional moves. Subjects in more aroused mood spent less time deliberating, revealed less information, ignored more product-describing attributes, and re-examined less of previously examined information. Study 2 replicated many of these effects with experimentally manipulated emotions and using a managerial decision-making task. The results are interpreted in terms of (1) a congruency between one's hedonic state and selected decision strategy and (2) a restriction in attentional capacity induced by increased Arousal.     

Pathways to mental health care by members of a rural community in South Africa

This study explored mental health help seeking pathways followed by Black South African rural community dwellers in the Limpopo province of South Africa. Ten participants (5 females and 5 males) aged between 18 and 59 years receiving services from a rural mental health care facility in the Limpopo province were the informants. They presented with psychotic disorders?=?50%, substance-use mental disorders?=?20%, mood disorders?=?20% and epilepsy?=?10%. They completed a semi-structured one-to-one interview on their pathways to mental health care services. Data were content analysed. The results showed that help seeking pathways for mental health involve several entry points. These include the utilisation of western medicine when experiencing acute symptoms, and a preference for traditional medicine when faced with chronic but manageable symptoms. The findings suggest that families and significant others are important facilitators for individuals navigating the mental health care pathways.     

Remembering Friends as Not So Friendly in Competitive and Bargaining Social Interactions

From children's schoolyard play to executives' boardroom negotiations, competitive and bargaining interactions are common to everyday life. Sometimes, the interacting parties are socially close and sometimes not. In this research, we examine how friendship influences memory for actions in such interactions. Dyads consisting of either friends or strangers played a competitive card game (Study 1) or the ultimatum game (Studies 2 and 4) and then recalled the interaction. We find that participants remembered friends' play as more competitive (Study 1) and less generous (Studies 2 and 4) than strangers' play, even when friends' actual play was more generous than that of strangers (Studies 2 and 4). Friendship did not affect recall for one's own play. In a workplace setting, Study 3 reveals people expect more of work colleagues who are friends than of work colleagues who are acquaintances. Study 4 tests our complete model and shows that people expect more of friends than of strangers and that this difference in expectations explains the less favorable memory for friend's actions. Our findings are consistent with a negative disconfirmation account whereby people expect their friends to be less competitive and more generous, and when these expectations are violated, people remember friends' actions more negatively than they actually were. Much research shows positive effects of friendship norms on actual behavior. We demonstrate a negative effect on people's memory of friends' behavior in competitive and bargaining social interactions. Copyright © 2017 John Wiley & Sons, Ltd.     

Orienting of attention, pupil size, and the norepinephrine system

This research examined a novel suggestion regarding the involvement of the locus coeruleus-norepinephrine (LC-NE) system in orienting reflexive (exogenous) attention. A common procedure for studying exogenous orienting of attention is Posner's cuing task. Importantly, one can manipulate the required level of target processing by changing task requirements, which, in turn, can elicit a different time course of inhibition of return (IOR). An easy task (responding to target location) produces earlier onset IOR, whereas a demanding task (responding to target identity) produces later onset IOR. Aston-Jones and Cohen (Annual Review of Neuroscience, 28, 403-450, 2005) presented a theory suggesting two different modes of LC activity: tonic and phasic. Accordingly, we suggest that in the more demanding task, the LC-NE system is activated in phasic mode, and in the easier task, it is activated in tonic mode. This, in turn, influences the appearance of IOR. We examined this suggestion by measuring participants' pupil size, which has been demonstrated to correlate with the LC-NE system, while they performed cuing tasks. We found a response-locked phasic dilation of the pupil in the discrimination task, as compared with the localization task, which may reflect different firing modes of the LC-NE system during the two tasks. We also demonstrated a correlation between pupil size at the time of cue presentation and magnitude of IOR.     

Stroop interference effects in partially colored Stroop words

In the Stroop task word reading is thought to be automatic since it runs without intentional monitoring and is difficult to avoid. This view has recently been challenged by observations that Stroop interference is reduced when only part of the Stroop word is colored. In this study we asked whether the extent of Stroop interference varies with the position of the colored letter(s). We observed that Stroop interference was smallest when the first letter(s) were colored and largest when either the last letter(s) or whole word were colored. On these findings we suggest that colored and noncolored parts of partially colored words are processed separately and differently, and that selection of the color dimension for explicit report entails inhibition of the to-be-ignored colored letters.     

Probabilistic versus “Pure” Volitional Orienting: a Monocular Difference

Human volitional orienting is typically assessed using Posner’s endogenous cuing task. As a volitional process, the literature has long emphasized the role of neocortical structures in this higher cognitive function. Based on recent data, we explored the possibility that subcortical channels may have a functional role in volitional orienting as measured by a Posner cuing task in which a nonspatial feature of a centrally presented cue is predictively related to the location of the target. In addition, we have compared this typical cuing task to a "purer" version, which does not involve the probability manipulation. A sensitive behavioral method was used to probe the contribution of monocular channels (mostly subcortical) in the two types of endogenous orienting tasks. In both tasks, a spatially informative cue and its ensuing target were presented to the same or different eyes at varying cue-target intervals. In the typically used endogenous task, the onset of facilitation was apparent earlier when the cue and target were presented to the same eye. In contrast, in the "pure" task no difference was found between the two eye-of-origin conditions. These data support the notion that endogenous facilitation, as measured in the typical Posner cuing task, involves lower monocular regions. Hence, in the typical endogenous task, which was developed to explore "volitional" orienting, a simple associative learning mechanism might elicit monocular, rapid orienting responses. Notably, the typical volitional orienting paradigm might be contaminated by simple contingency benefits and thus may not provide a pure measure of volitional processes.

     

Community and subcommunity in small-town America, 1880–1950

Throughout the late nineteenth and early twentieth centuries, the American Jewish population was heavily concentrated in the large and mid-size cities of the United States. At the same time, however, tens of thousands of Jews lived in America's smaller cities and towns as well. This essay examines how some of the basic features of Jewish life in the immigrant era were manifested in America's less visible Jewish centers. It discusses the nature of East European Jewish culture in small towns, and demonstrates that factors such as kinship, residential and occupational patterns, the use of Yiddish, and local institutional frameworks all promoted more highly integrated and intensively Jewish ethnic communities than might have been expected in small-town America. The essay also examines the relationship between German Jews and East Europeans in small towns and considers various other aspects of communal dynamics. In doing so, it describes how in some places a kind of cooperation and creative compromise developed that did not emerge in larger communities, and it reveals how in other places communal divisions persisted despite environmental factors that should have promoted their moderation. Ultimately, this essay demonstrates that the communities of America's smaller cities and towns in the decades before World War II were not simply miniature versions of the communities of larger metropolitan areas, and it suggests that for those interested in the dynamics of Jewish communal life, smaller Jewish settlements can provide valuable laboratories in which to study the role of place in conditioning the American Jewish experience.
