This pilot randomized control trial (RCT) tested “Do More, Feel Better” (DMFB), a lay-delivered Behavioral Activation intervention for depressed senior center clients. The study examined: 1. the feasibility of training older lay volunteers to fidelity; and 2. the acceptability, safety, and impact of the intervention. Twenty-one lay volunteers at four senior centers were trained in DMFB. Fifty-six depressed clients were randomized to receive 9 sessions of DMFB or Behavioral Activation delivered by social workers (MSW BA). Research assessments of overall client activity level (BADS) and depression severity (HAM-D) were conducted at baseline and weeks 3, 6, and 9. Eighty-one percent of lay volunteers who underwent training were formally certified in DMFB. Depressed clients receiving each intervention reported high levels of satisfaction and showed large and clinically significant changes in 9-week activity level (d ≥ 1.35) and depression severity (d ≥ 3.34). Differences between treatment groups were very small for both activity level (dMSW = 0.16; 95% CI, -0.70 to 1.02) and depression (dMSW = 0.14; 95% CI, -0.63 to 0.91). Increases in activity level were associated with decreases in depression (β = -0.42; 95% CI, -0.55 to -0.30). Both interventions appeared to work as intended by increasing activity level and reducing depression severity. “Do More, Feel Better” shows the potential of evidence-based behavioral interventions delivered by supervised lay volunteers, and can help address the insufficient workforce available to meet the mental health needs of community-dwelling older adults.

Intimate relationships matter to health and happiness. However, the vast scope of relationship research and the abundance of precise micro-theories has presented obstacles to the development of integrative theories with contextual-behavioral foundations that are oriented towards application of findings in domains of public health significance. Derived from the well-validated Interpersonal Process Model, which described intimacy as a dyadic exchange in which Person A engages in a vulnerable self-disclosure, Person B enacts a response, and Person A perceives the response as responsive, we present an integrative, analytic-abstractive, contextual-behavioral model of intimate relations. The model describes the intimacy process as a set of functional relations describing behaviors and responses of Persons A and B in context, languaged as middle-level terms to facilitate cross-disciplinary applications. Three primary relations of the model are non-verbal emotional expression (Person A) and safety (Person B), verbal self-disclosure (Person A) and validation (Person B), and asking (Person A) and giving (Person B). The model also emphasizes the importance of self- and other-awareness, expressions of closeness, and reciprocity as additional terms. Future research directions and potential applications are discussed.

Previous research on microaggressions has emphasized the frequency of and distress produced by microaggressions as reported by people of color. The current research supplements the existing literature by developing a self-report measure of White individuals’ microaggressive likelihood against Black people, the Cultural Cognitions and Actions Scale (CCAS). Study 1 developed the CCAS through exploratory and confirmatory factor analyses of responses to CCAS items from a sample of 978 non-Hispanic White undergraduate students. The final scale comprised four factors (Negative Attitudes, Colorblindness, Objectifying, and Avoidance) assessing microaggressive likelihood, and CCAS total and factor scores were significantly related to several other indicators of racism and bias. Study 2 involved 31 of the previous participants in a lab-based discussion of race-related issues with a confederate and provided initial support for the predictive validity of the measure. Overall, this report supports a growing literature that microaggressions are more than innocuous, harmless behaviors, unrelated to racism, and instead represent relevant processes within the science of racism and bias. It also provides a potential means of testing the effectiveness of interventions intended to reduce the commission of microaggressions.

Theories of dishonest behavior implicitly assume language independence. Here, we investigated this assumption by comparing lying by people using a foreign language versus their native tongue. Participants rolled a die and were paid according to the outcome they reported. Because the outcome was private, they could lie to inflate their profit without risk of repercussions. Participants performed the task either in their native language or in a foreign language. With native speakers of Hebrew, Korean, Spanish, and English, we discovered that, on average, people inflate their earnings less when they use a foreign language. The outcome is explained by a dual system account that suggests that self‐serving dishonesty is an automatic tendency, which is supported by a fast and intuitive system. Because using a foreign language is less intuitive and automatic, it might engage more deliberation and reduce the temptation to lie. These findings challenge theories of ethical behavior to account for the role of the language in shaping ethical behavior.

High quality relationships are essential to psychological health and well-being, and relational intimacy is a core feature of these relationships. Decades of research in relationship science have converged on a central model of intimacy wherein individuals develop close, trusting relationships with one another. Functional Analytic Psychotherapy (FAP) is a contextual behavioral intervention approach that is well-equipped to target interpersonal processes through the provision of in-session, therapist mediated reinforcement of skillful intimate relating. Single-subject level analyses of FAP's efficacy and mechanism of action are supportive; however, there is a need for group-level research to evaluate its efficacy and generalizability. This paper presents the development of the Awareness, Courage, and Responsiveness Scale (ACRS), a self-report measure of behaviors essential to intimate relating informed by contextual behavioral science principles and Reis and Shaver's (1988) Intimacy Process Model. In this five-part study, functioning of the ACRS is examined in undergraduate student samples (Studies 1–3), an adult community sample (Study 3), non-clinical dyadic relationships (Study 4), and a transdiagnostic clinical sample (Study 5). Strengths and limitations of the final measure are discussed.

BackgroundRacial bias in medical care is a significant public health issue, with increased focus on microaggressions and the quality of patient-provider interactions. Innovations in training interventions are needed to decrease microaggressions and improve provider communication and rapport with patients of color during medical encounters.MethodsThis paper presents a pilot randomized trial of an innovative clinical workshop that employed a theoretical model from social and contextual behavioral sciences. The intervention specifically aimed to decrease providers’ likelihood of expressing biases and negative stereotypes when interacting with patients of color in racially charged moments, such as when patients discuss past incidents of discrimination. Workshop exercises were informed by research on the importance of mindfulness and interracial contact involving reciprocal exchanges of vulnerability and responsiveness. Twenty-five medical student and recent graduate participants were randomized to a workshop intervention or no intervention. Outcomes were measured via provider self-report and observed changes in targeted provider behaviors. Specifically, two independent, blind teams of coders assessed provideremotional rapportandresponsivenessduring simulated interracial patient encounters with standardized Black patients who presented specific racial challenges to participants.ResultsGreater improvements in observed emotional rapport and responsiveness (indexing fewer microaggressions), improved self-reported explicit attitudes toward minoritized groups, and improved self-reported working alliance and closeness with the Black standardized patients were observed and reported by intervention participants.ConclusionsMedical providers may be more likely to exhibit bias with patients of color in specific racially charged moments during medical encounters. This small-sample pilot study suggests that interventions that directly intervene to help providers improve responding in these moments by incorporating mindfulness and interracial contact may be beneficial in reducing racial health disparities.

The interpersonal process model (IPM) suggests that closeness develops in relationships when two people reciprocally engage in vulnerable self-disclosure, respond to each other, and perceive each other’s responses as validating, understanding, and caring (responsive). Little is known about how fear-of-intimacy relates to this foundational intimacy process. We conducted two studies of fear-of-intimacy and the IPM. In Study 1, 146 high fear-of-intimacy participants were randomly assigned to either interact for 1 hr with a research assistant (RA) demonstrating high responsiveness, to interact for 1 hr with an RA displaying low responsiveness, or to view a nature video for 1 hr. Unlike previous experiments with undergraduates documenting that high responsiveness predicts closeness up to 2 weeks after the interaction, the current study with high fear-of-intimacy individuals found that high responsiveness predicted closeness immediately after the interaction but this was not sustained over time. In Study 2, we conducted structural modeling in a diverse sample of 216 survey respondents with a range of fear-of-intimacy scores. Consistent with previous studies, perceived responsiveness strongly predicted closeness. Fear-of-intimacy had negative direct effects on vulnerable self-disclosure and perceived responsiveness but a positive direct effect on closeness.

What is liberalism? What accounts for its tendency to change over time? Corey answers these questions by situating liberalism within a much broader, more powerfully sweeping historical movement, the “modern quest for freedom.” This movement predates liberalism, gives rise to it, and eventually overtakes it in its original form while retaining the name “liberalism,” especially in the United States, for reasons partly principled, partly expedient. Corey’s historical presentation of liberalism facilitates a unique assessment of some of its current weaknesses. This in turn makes possible a concrete discussion of what an effort to “reclaim” liberalism might look like. Ultimately, Corey argues that the politics of warring freedoms (what contemporary liberalism has in part become) should give way to a markedly different conception of politics called the politics of liberal truce.

The US has never been more divided politically. Polarization is notable on majority-liberal college campuses where conservatives feel outnumbered and marginalized. In this study, we examined the effectiveness of a half-day workshop to decrease polarization and improve closeness between conservatives and liberals at a majority-liberal college campus. Informed by political psychology and relationship science, the intervention employed exercises derived from Acceptance and Commitment Therapy and Functional Analytic Psychotherapy to encourage identification of core beliefs and vulnerable discussions of deeper reasons for core political beliefs aimed at generating closeness and understanding between participants. Participants (N = 20) were assigned to 2 groups: one of mixed conservatives and liberals, and one of all liberals. All participants reported improvements in attitudes and hostility towards outgroup members from pre- to post-workshop, but only differences in relations with specific outgroup workshop participants were maintained at 1-month follow-up. Participants also reported arguing less than expected.

Background This study analyzed visits for and factors associated with gout and gout medication treatment trends for the years 2007–2011 in the United States given the introduction of febuxostat, the first new treatment option for gout in over 40 years, which was introduced to the market in 2009. Methods This study was a retrospective, cross-sectional, observational study of patients age 20 and older seen by providers who participated in the National Ambulatory Medical Care Survey (NAMCS), the National Hospital Ambulatory Medical Care Survey Outpatient Department (NHAMCS-OPD) or Emergency Department (NHAMCS-ED) in the United States. The outcome of interest was visits for gout diagnosis and visits where a gout medication was prescribed. Results Approximately 1.2% of visits had a diagnosis of gout. There was a significant increase in the percentage of visits with a diagnosis of gout in years 2009–2011 compared to 2007–2008, which remained after adjusting for covariates of interest. Groups more likely to have a visit with gout included those ≥65 and 45–64 (both as compared to those 20–44), the African-American and ‘Other’ race groups (as compared to Caucasians) and those on a diuretic. Groups less likely to have a visit with gout included females, Hispanic/Latinos, those with insurance type of ‘Other’ and Medicaid (both as compared to private insurance) and visits to a hospital emergency setting (as compared to physician’s office visits). Conclusion Although there was a significant increase in visits where gout is diagnosed across study years, the overall percentage of visits with a gout diagnosis is low in the US population. Treatment trends over the study years has remained consistent, with the introduction of febuxostat appearing to have little impact for the study years through 2011.

We explore the origin of the foreign language effect on moral judgements by assessing whether language context alters the weight given to intentions and outcomes during moral judgement. Specifically, we investigated whether foreign language contexts, compared with native ones, may lead people to focus more on the outcomes of an action and less on the intentions behind it. We report two studies in which participants read scenarios in which the actor’s intentions and the resulting consequences were manipulated. As previously shown, people considered both the actor’s intentions and the action’s outcomes when assessing the damage, cause, moral wrongness, responsibility, and punishment deserved. However, although the foreign language context reduced the impact of intentions on damage assessment, the overall effect of intention and outcomes on these variables was mainly the same in the foreign and the native language contexts. We conclude that differential weighting of intentions and outcomes is unlikely to account for the impact of foreign language use on moral judgement.

Michael Oakeshott worried that during his lifetime, liberal democracies had become dangerously oblivious to the problem of political legitimacy—the problem of ensuring that government power be used in ways that respect the freedom and political equality of all citizens. This essay deepens Oakeshott’s concern by arguing that there has never been a successful theoretical argument to establish why some citizens should be able to exercise political power over other citizens under conditions of freedom and political equality. The author concludes by considering the implications of this argument for the size and scope of liberal government today, particularly in the USA.

It may seem reasonable to think that our moral decisions (and selves) do not depend on which language we are using (native or foreign). However, recent evidence suggests that the language in which decision information is presented affects subsequent choices. The use of a foreign language, compared to a native one, leads to an increase in utilitarian choices in particularly difficult or emotional decisions. Possible mechanisms are discussed.

Puede parecer razonable pensar que nuestras decisiones morales (y naturalezas morales) no dependen de la lengua que usemos (nativa o extranjera). Sin embargo, estudios recientes sugieren que la lengua en la que se presenta la información relevante afecta las decisiones subsecuentes. El uso de una lengua extranjera, comparado con el de una nativa, lleva a un incremento de elecciones utilitaristas en decisiones que son particularmente difíciles o emocionales. Terminamos con una discusión de posibles mecanismos.

Though moral intuitions and choices seem fundamental to our core being, there is surprising new evidence that people resolve moral dilemmas differently when they consider them in a foreign language (Cipolletti et al., 2016; Costa et al., 2014a; Geipel et al., 2015): People are more willing to sacrifice 1 person to save 5 when they use a foreign language compared with when they use their native tongue. Our findings show that the phenomenon is robust across various contexts and that multiple factors affect it, such as the severity of the negative consequences associated with saving the larger group. This has also allowed us to better describe the phenomenon and investigate potential explanations. Together, our results suggest that the foreign language effect is most likely attributable to an increase in psychological distance and a reduction in emotional response.

Published online: 22 January 2016 In this study we explore whether world knowledge (WK) processing differs between individuals listening to their native (L1) or their non-native (L2) language. We recorded event-related brain potentials in L1 and L2 speakers of Spanish while they listened to sentences uttered by native speakers of Spanish. Sentences were either congruent or incongruent with participants’ WK. In addition, participants also listened to sentences in which upcoming words could not be anticipated on the basis of WK. WK violations elicited a late negativity of greater magnitude and duration in the L2 than the L1 group. However, sentences in which WK was not helpful regarding word anticipation elicited similar N400 modulations in both groups. These results suggest that WK processing requires a deeper lexical search in L2 comprehension than in L1 comprehension This research was approved by the ethics committee of the Spanish Ministry of Economy and Finance, which funded this study.We thank Silvia Blanch and Xavier Mayoral for their technical support, and Meritxell Ayguasanosa for assistance in testing participants.

Michael Oakeshott's critique of ‘political rationalism’ is often regarded as a unique contribution to the study of 20th-century ‘ideologies.’ But, in fact, Oakeshott understood rationalism and ideology as distinct phenomena. This article exposes the essence of each in Oakeshott's writings, analyses their complex relationship and shows how far back in human history they reached. Neither was, for Oakeshott, distinctly modern. In fact, he traced ideology and rationalism alike to the birth of philosophy in ancient Greece, even while he acknowledged important differences in their ancient and modern manifestations. Oakeshott's outlook with respect to these phenomena was significantly more pessimistic than that of other 20th-century analysts. He did not think our problems were easily curable. He did, however, harbour some hope (albeit dreamy) that in the domain of politics in particular, the metaphor of ‘conversation’ might somehow loosen the grip of ideological thought and action.

This article describes liberal education as it comes to light not historically but philosophically, taking the word liber (free) as its chief distinguishing feature. It considers what liberal education presupposes of those who pursue it, and it enumerates several outcomes or “ends” that are likely to ensue. Through liberal education, I argue, the mind is liberated from the here and now, freed by exposure to diverse kinds of character, released from the tyranny of the practical mode of thought, and, at the same time, freed by certain careful habits of reflection that take years to acquire.

11 April 2013 marks the 50th anniversary of the papal encyclical, Pacem in Terris, a document that has exerted enormous influence on the doctrines of war and peace articulated by Roman Catholic and non-Catholic writers alike. The argument we make here is that in its understanding of human rights, international peace and philosophical anthropology, the encyclical in effect abandons the ‘just war’ teachings that had guided the church's view of human conflict for 16 centuries, and we argue that the departure is a mistake.

Management practices that build soil organic matter—including reduced tillage, cover cropping, and compost applications—may be useful for protecting vulnerable crops from extreme weather events, reducing energy costs, and suppressing pests in carrot (Daucus carota subsp. sativa) production systems. The primary objective of this research was to assess the effects of strip tillage, compost, and carrot cultivar on carrot quality, yield, and profitability. An important secondary objective was to evaluate the impact of tillage and compost on establishment of important weeds in carrot systems—including two species that have developed resistance to linuron: Powell amaranth (Amaranthus powellii) and common purslane (Portulaca oleracea). Field experiments were conducted in 2009 and 2010 comparing conventional tillage (CT) to strip tillage (ST) under two rates of mature compost addition (0 or 3 dry t·ha−1) for three processing carrot varieties (‘Canada’, ‘Finley’, and ‘Recoleta’). In the ST system, a pre-established barley cover crop was left to grow as a windbreak between crop rows until carrots were established. Partial budget analysis was used to estimate net returns associated with all treatments. Compared with CT, the ST system resulted in 1) either equivalent or greater (2010, Finley cultivar) total carrot yields and net returns; and 2) either equivalent or lower summer annual weed densities. Addition of compost resulted in equivalent (2010) or higher (2009) carrot yields and gross returns but did not affect net returns as a result of the increased costs associated with compost application. Compost reduced the density of common purslane in 2009 but resulted in a threefold increase in the density of Powell amaranth in 2010. Our results demonstrate that both ST and compost applications are potentially valuable tools for improving the profitability of carrot production systems. Future research examining the mechanistic basis for compost and tillage effects on carrots and weeds as well as the long-term effects of these practices on profitability of rotational crops would be helpful for optimizing their use in vegetable production systems.

Living mulches growing below asparagus (Asparagus officinales) fern can improve soil health and suppress weeds but may also suppress asparagus through competition for water or nutrients. The central objective of this research was to test whether cereal rye (Secale cereale) living mulch, in combination with overhead irrigation, could provide comparable weed suppression to standard residual herbicides without reducing asparagus yields. A field experiment was conducted from 2008 to 2010 in a mature asparagus planting on sandy soils in western Michigan to evaluate the effects of irrigation (none vs. overhead) and weed management systems (standard herbicides vs. rye living mulch) on weed suppression, soil moisture content, and asparagus yield. Rye living mulch and herbicide treatments were established immediately after asparagus harvest in late June of each year. Rye living mulch reduced soil-available water in early August by 26% to 52% compared with herbicide treatments but had no detectable effect on asparagus yields. Compared with herbicide treatments, rye living mulch reduced fall-germinating weed emergence and resulted in lower densities of horseweed (Conyza canadensis) during asparagus harvest. However, in 2 of 3 years, the living mulch system resulted in higher densities of summer annual weeds—including Powell amaranth (Amaranthus powellii) and longspine sandbur (Cenchrus longispinus)—during the fern growth period compared with herbicide treatments. After 3 years, the density of summer annual weeds was more than 10-fold greater in rye living mulch treatments compared with standard residual herbicides treatments. Our results suggest that 1) soil-improving rye cover crops can partially suppress weeds but may also compete with asparagus for soil moisture in dry years unless irrigation is used; and 2) successful use of rye living mulches for weed management will depend on identification of complementary weed management practices to avoid build-up of the summer annual weed seedbank.

Historians of the just-war tradition frequently cite Martin Luther as a major proponent of the just war in the sixteenth century and assimilate his views to those of earlier writers such as Augustine and Thomas Aquinas. In this study I show that Luther's relationship to the just-war tradition was more complex than scholars typically acknowledge. Although he adopted a just-war outlook in general, he sometimes ignored or rejected aspects of the tradition, and this led to two possible outcomes. In some instances, Luther's teaching appears less nuanced and coherent than earlier teachings, for example on the topics of just cause and jus in bello. In other ways, though, Luther helped to advance the tradition, for example on the topics of holy war and the personal responsibility of soldiers.

Conventional anti-cancer drug screening is typically performed in the absence of accessory cells of the tumor microenvironment, which can profoundly alter anti-tumor drug activity. To address this major limitation, we developed the tumor cell-specific in vitro bioluminescence imaging (CS-BLI) assay. Tumor cells (e.g. myeloma, leukemia and solid tumors) stably expressing luciferase are co-cultured with non-malignant accessory cells (e.g. stromal cells) for selective quantification of tumor cell viability, in presence vs. absence of stromal cells or drug treatment. CS-BLI is high-throughput scalable and identifies stroma-induced chemoresistance in diverse malignancies, including imatinib-resistance in leukemic cells. A stromal-induced signature in tumor cells correlates with adverse clinical prognosis and includes signatures for activated Akt, Ras, NF-κB, HIF-1α, myc, hTERT, and IRF4; signatures for biological aggressiveness and for self-renewal. Unlike conventional screening, CS-BLI can also identify agents with increased activity against tumor cells interacting with stroma. One such compound, reversine, exhibits more potent activity in an orthotopic model of diffuse myeloma bone lesions than in conventional subcutaneous xenografts. Use of CS-BLI, therefore, enables refined screening of candidate anti-cancer agents to enrich preclinical pipelines with potential therapeutics that overcome stroma-mediated drug resistance and can act in a synthetic lethal manner in the context of tumor-stromal interactions.

Socrates was not only a paradigmatic philosopher; he was also a paradigmatic citizen according to some contemporary political theorists—paradigmatic for his moral integrity and his political practices of dissent and noncompliance. What is perhaps most exemplary about Socrates, according to some commentators, is that his citizenship was “purely secular,” relying upon no sources of authority beyond the naked moral self. The present article challenges this dominant view of Socratic citizenship by examining Socrates′ relationship to the oracle at Delphi and the mysterious divine sign that frequently turned him away from certain civic activities. Arguing that these sources of authority affected Socrates′ practice of citizenship in significant ways, the essay presents a picture of Socrates that is at once truer to the texts to which these secular views appeal and more instructive for contemporary theorizing about citizenship.

The article examines Voegelin's understanding of nous as the ground for theorizing, and relates this back to Aristotle. Aristotle is shown to have understood the activities of nous in two distinct ways. On the one hand, nous is the divine activity of the soul exploring its own ground. But nous is also induction (epagôgê) of the first principles of science through sense perception, memory and experience. The two basic activities of nous are related, but they have different values when it comes to the world of particulars. The argument is that a substantive ethical and political science—one that sheds light on particulars—must include the inductive employment of nous and that the exclusion of this from Voegelin's political science results in some discernible limitations.The limitations of Eric Voegelin—s work are sometimes difficult to keep in view, particularly while he is expounding upon the totality of Being, the myriad dimensions of human consciousness, and the nature of order in personal, social, and historical existence. But in fact Voegelin's work is more limited than his magisterial tone might suggest. The argument of this article is that while Voegelin offers his readers profoundly important insights into the structure of human consciousness and into what Aristotle called first philosophy, the study of being qua being, he does not offer his readers much in the way of a substantive ethical or political science.

An approach is presented for modeling board-level, package-level, and multichip module (MCM) substrate-level interconnect circuitry based on measured time-domain reflectometry (TDR) data. The time-domain scattering parameters of a multiport system are used to extract a SPICE netlist from standard elements to match the behavior of the device up to a user-specified cutoff frequency. Linear or nonlinear circuits may be connected to the model ports, and the entire circuit simulated in a standard circuit simulator. Two- and four-port microstrip-circuit examples are characterized, and the simulation results are compared with measured data. Delay, reflection, transmission, and crosstalk are accurately modeled in each case.
