Identity and Engagement among Political Independents in America

Political behavior among independents has been documented for decades, yet we are left with limited insight into their political engagement. What, if anything, motivates independents to engage in politics? In this study, I apply psychological theories of attitude importance to explain high variation in political‐engagement levels among independents. Using two recent datasets, I find engagement levels are comparable across independents and partisans, yet predictors of their engagement differ substantially. Ideological strength predicts engagement for partisans—but not for independents. Instead, my data show that independents' engagement is best predicted by the importance they place on their independent identity. These data provide evidence that independence is a meaningful political identity and that identity importance is a key to explaining what motivates the independent voter to engage with politics.     

Comparing two career adaptability measures for career construction theory: Relations with boundaryless mindset and protean career attitudes

We examined the constructs underlying the Career Maturity Inventory-Adaptability Form (CMI-C) and the Career Adapt-Abilities Scale (CAAS). Data from 852 university students indicated that the second-order factors for both scales correlate .43, suggesting that they measure different yet related constructs. All three subscales of the CMI-C correlate most with the “concern” subscale of the CAAS rather than with the corresponding subscale. It appears that the CMI-C is a measure of particular career adaptability for choosing a career whereas the CAAS is a global measure of career adaptability for dealing with all of the tasks of vocational development across the life span. Regression analyses show that the CMI-C does not add to the prediction of boundaryless mindset and protean career attitudes over the CAAS. Relationships between the CMI-C and CAAS with entrepreneurial, professional, and leadership career motivation profiles showed that the CAAS is more strongly related to boundaryless mindset and protean career attitudes, while the CMI-C appears to relate to more traditional (professional and leadership) career motivations.     

Muscle strength and functional performance is markedly impaired at the recommended time point for sport return after anterior cruciate ligament reconstruction in recreational athletes

PurposeTo examine potential deficits in muscle strength or functional capacity when comparing (1) an ACL reconstructed group to matched healthy controls, (2) the ACL reconstructed leg to the non-injured leg and (3) the non-injured leg to matched healthy controls, at the time-point of recommended sport return 9–12 months post-surgery.MethodsSixteen patients (male-female ratio: 9:7) 9–12 months post ACL reconstruction and sixteen age and sex matched healthy controls were included. Outcome measures included maximal knee extensor (KE) and knee flexor (KF) dynamometry, including measurement of rate of force development, functional capacity (counter movement jump (CMJ) and single distance hop (SDH)) and the Lysholm score.ResultsCompared to the control group, maximal KE and KF muscle strength were impaired in the ACL reconstructed leg by 27–39% and 16–35%, respectively (p < .001). Also, impairments of both CMJ (38%) and SDH (33%) were observed (p < .001). Rate of force development for KE were reduced in the ACL group compared to the control group (p < .001). Similarly, the KE and KF muscle strength, CMJ and SDH of the ACL reconstructed leg were impaired, when compared to the non-injured leg by 15–23%, 8–20%, 23% and 20%, respectively (p < .05).ConclusionMuscle strength and functional capacity are markedly impaired in the ACL reconstructed leg of recreationally active people 9–12 months post-surgery when compared to healthy matched controls and to their non-injured leg. This suggests that objective criteria rather than “time-since-surgery” criteria should guide return to sport.     

群际态度与群际信念:耦合还是分离?

群际态度是人们对于某一群体的喜欢或不喜欢,包括外显群际态度和内隐群际态度,它是一个群体对另一群体正负连续体的评价。群际信念是人们对某一群体特性的刻板印象。以往研究认为,群际态度和群际信念是耦合关系,相互影响,相倚存在。但群际态度和群际信念也存在分离性证据,即存在矛盾性和非统一性。为何形成耦合或者分离,文化定型论、群际态度补偿机制(低地位群体的创造策略、高地位群体的慷慨策略),以及认知差别等都成为调节性平衡点。探讨群际态度和群际信念的分离性关系和作用机制对于干预和消弭群际边界与群际冲突,缓和群际关系具有深远影响,可以支持其独立路径予以针对性干预方案。     

The motivations for Walter Burley’s theory of the proposition

Walter Burley (born c. 1275; died. c. 1344) claims throughout his career that the mind can make a statement (propositio) out of things. Since things include entities that exist outside of the mind, Burley appears to be claiming that the mind can form a statement out of things that exist outside of it. Most scholars of Burley offer a deflationary reading of this claim, arguing that it confuses two distinct but closely related philosophical issues: the nature of propositional content, on the one hand, and the role of facts in a compelling account of truth, on the other. But I argue that Burley means exactly what he says: that the mind can, quite literally, form statements out of things that exist outside of it. In Burley’s account, statements of this sort function as the propositional contents of our thoughts and written or uttered sentences. This account of propositional content is motivated by three more fundamental theses to which Burley is committed: referentialism, compositionality, and a claim about truth-conditionality I call intellectualism.     

儿童青少年优秀品质的基本特点与模式*

采用优势行动价值问卷儿童青少年版（VIA-Youth）对947名城市儿童青少年进行调查,以探究儿童青少年优秀品质的基本特点,包括各种优秀品质的性别及年龄特点,以及儿童青少年优秀品质的组合模式等。研究得出以下结论：在24种优秀品质中,儿童青少年得分最高的5种分别是领导力、信仰、审慎、谦虚和正直,得分最低的5种为幽默、善良慷慨、感恩、宽容和好奇心。男生的好奇心得分显著高于女生,女生的情感智力和自我控制得分显著高于男生,在其他优秀品质上不存在显著性别差异;除创造力、信仰等5种优秀品质以外,八年级青少年的优秀品质得分均显著高于五年级儿童。潜剖面分析表明,儿童青少年优秀品质表现为高优秀品质组、中等略低优秀品质组和低优秀品质组3种不同的组合模式,3种组合模式的分布不存在显著的性别和年级差异。     

An Intuitionist Theory of Argument Strength in Politics: How Intuitive Cognitive Biases Produce Universally Strong Arguments

Why are some political arguments more persuasive than others? Extant theories have mainly explained argument strength with reference to familiarity. Such explanations suggest that arguments are only strong for particular populations: those living in particular cultures, those following particular news, or those holding particular political values. Here, we argue for and identify the existence of a universally strong class of arguments transcending such divides: arguments that are congruent with intuitively held cognitive biases. We focus on arguments about social welfare that are congruent with a particular cognitive bias: the deservingness heuristic. Embedding a novel experiment in representative surveys in the United States, Japan, and Denmark, we demonstrate that people intuitively process arguments that resonate with this heuristic and that such arguments are strong across cultural divides, across individual levels of familiarity with the arguments, and across individual differences in political values. Finally, against the idea that intuitive arguments are simplistic, we demonstrate that such arguments can be inferentially complex, as long as they resonate with a cognitive bias.     

Response–reinforcer contiguity versus response-rate–reinforcer-rate covariance in rats' lever pressing: Support for a multiscale view

The multiscale molar view sees behavior as a flow, like a river, extended in time. Matching theory expresses the way activities compete for time. Relative time taken by any activity depends on relative induction. The present experiment tested matching theory applied to concurrent contingent and noncontingent food. As adjunctive activities that compete with operant activity, we recorded hopper head entries and presses on a lever near the food hopper that had no programmed consequences. Eight naïve rats were first exposed to a variable-time 60 s schedule, which across conditions was gradually transformed into a variable-interval 60 s schedule by increasing the proportion of food that was delivered contingent on pressing a lever far from the hopper. Another group of 4 rats that had been trained to press a lever near a food hopper were introduced in the second condition, in which one food delivery was contingent on far-lever pressing. We found induction following a power function to describe pressing on the far lever (operant activity). Matching theory combined with power-function induction also accounted for adjunctive activity. Results with single contingent food deliveries provided little support for the molecular view that behavior consists of discrete responses “strengthened” by immediately following reinforcers.
