Value themes were extracted from U.S. presidential inaugural addresses of the 19th and 20th centuries. The values most frequently extolled were liberty, belief in God, patriotism, justice, personal responsibility, and peace. More references to lowering taxes were made in the 19th compared with the 20th century and by Republicans compared with Democrats. Truth/honesty was more frequently mentioned in the 19th century than in the 20th century, but courage was more frequently mentioned in the 20th century. Implications are discussed.  相似文献

This essay surveys recent scholarship on the history of ethnicity in Latin America and the Atlantic World, exploring ways in which Jewish, Japanese and Middle Eastern minorities have transacted nationhood, identity and integration. This historiography of ethnicity offers compelling paths for understanding how transnational identities are negotiated. These include the analysis of patterns of slaveholding by Jewish communities on both sides of the Atlantic and the ways in which these communities understood blackness; the use of memory in understanding experiences of immigration; the relationships between national foreign policy and domestic ethnic politics; and the extent to which the issues of negotiating identity and asserting ethnicity are shared by a variety of immigrant ethnic groups. Together, this body of literature reflects the substantial ways in which ethnic histories interplay with other facets of national histories and with the process of historical analysis.  相似文献

The marriage and family therapy (MFT) field would benefit from new research about positive subjective experiences, such as optimism, in order to construct and nurture strengths for developing more positive emotions. Through a better understanding of optimism, marriage and family therapists (MFTs) can explore which strategies might help families and individuals better cope with distressing emotions by building buffering strengths. In this study we address the relationship of differentiation, family coping, and family functioning to optimism. We found that differentiation, family coping, and family functioning each have a significant effect on attributional style. The results of this study also indicated that encouraging clients to take an I-position and to reframe problems, in particular, may lead to greater optimism. This study contributes to the lack of research regarding strength-based theories in the MFT field.  相似文献

Activation of the infralimbic region (IL) of the medial prefrontal cortex (mPFC) reduces conditioned fear in a variety of situations, and the IL is thought to play an important role in the extinction of conditioned fear. Here we report a series of experiments using contextual fear conditioning in which the IL is activated with the GABAa antagonist picrotoxin (Ptx) during a single extinction session in the fear context. We investigate the impact of this manipulation on subsequent extinction sessions in which Ptx is no longer present. First, we demonstrate that a single treatment with intra-IL Ptx administered in a conditioned fear context greatly accelerates the rate of extinction on the following days. Importantly, IL-Ptx also enhances extinction to a different fear context than the one in which IL-Ptx was administered. Thus, IL-Ptx primes extinction learning regardless of the fear context in which the IL was initially activated. Second, activation of the IL must occur in conjunction with a fear context in order to enhance extinction; the extinction enhancing effect is not observable if IL-Ptx is administered in a neutral context. Finally, this extinction enhancing effect is specific to the IL for it does not occur if Ptx is injected into the prelimbic region (PL) of the mPFC. The results indicate a novel persisting control of fear induced by activation of the IL and suggest that IL activation induces changes in extinction-related circuitry that prime extinction learning.  相似文献

Community coalitions represent a promising approach for addressing the interrelated and multiply- determined issues affecting urban neighborhoods of concentrated poverty. The literature suggests a number of community processes that may affect coalition efforts to change and improve communities. This study uses an interrupted time-series design to examine the effects of a strategic planning intervention on community change in two urban neighborhoods in the Kansas City metropolitan area. Results showed that strategic planning was associated with increased rates of community change in the two urban neighborhood coalitions. Under appropriate conditions, such as the presence of consistent leadership, strategic planning may be a particularly effective mechanism for stimulating community change and addressing locally-determined goals in urban neighborhoods.  相似文献

This study explored the relationship of gender and urban/rural driving to anger, anger expression, aggression, and risky behavior while driving. Some small gender effects were found. Men and women did not differ on anger or forms of anger expression, but men reported more aggressive and risky behavior. There were no urban/rural differences, except for one interaction. Urban males reported less overall driving anger than did other groups. Results are discussed in terms of absence of urban/rural differences and the need to explore potential differences in larger, more powerful designs that employ more diversified measures of anger and the impact of driving anger on a person's life.  相似文献

Four experiments examined the relative influence of three causal processes in the above-average effect (AAE) and related comparative biases: (a) egocentrism, (b) focalism, and (c) referent group diffuseness. By manipulating the inclusion or exclusion of the self from the referent group (Experiments 1-3) or target group (Experiment 4), the relative contributions of each influence were assessed. In direct comparisons, single peers were systematically judged more favorably relative to groups including the self, suggesting that egocentrism plays a lesser role than focalism or group diffuseness. Thus, in response to the question such as “How friendly is Nancy compared to the rest of us?” the answer tends to be “More friendly.”  相似文献

An unusual request can increase compliance in situations in which the typical response to the request is refusal. This procedure, called the pique technique, is said to be effective because the unusual request causes people to give mindful consideration to it. We tested this explanation in 2 studies. Passersby were asked for either a common amount of change or 37 cents. Participants who inquired about the unusual amount were given either a specific or an uninformative reason. The pique technique increased compliance, but only when participants stopped to ask about the request. These participants gave more money, regardless of the reason provided. The findings failed to support the notion that an unusual request leads to a mindful consideration of it.  相似文献

A 12-wk. study was conducted to contrast the effects of a longer and more frequent aerobic exercise protocol with a shorter and less frequent circuit strength-training protocol for improving U.S. Air Force physical fitness test scores of subjects who previously failed to achieve a passing point total. 83 men and women of the U.S. Air Force (M age = 32.7 yr.) participated in either the unsupervised standard conditioning program, which recommended approximately 60 min. of aerobic activity 4 to 5 days per week (n=26), or the supervised circuit strength-training program, which required approximately 25 min. of alternating strength and endurance exercises 3 days per week (n=57). Subjects were assessed on a 2400-m (1.5-mile) run, abdominal circumference, push-ups completed in 1 min., and abdominal crunches completed in 1 min. Dependent t tests with Bonferroni adjustment indicated that significant improvements were attained by the circuit strength-training group only on each of the aforementioned measures. Significantly more participants in the circuit strength-training group (26%) achieved a passing point total than in the standard conditioning group (19%) at Wk. 12 (chi1(2) =3.96, p = .05). Implications for enhancing physical fitness in poorly conditioned adults were discussed.  相似文献
