Responsibility to Protect and Militarized Humanitarian Intervention

My essay “Responsibility to Protect and Militarized Humanitarian Intervention: When and Why the Churches Failed to Discern Moral Hazard” (JRE 40.2) called for more questioning engagement with R2P than the broadly uncritical welcome given by the churches to the doctrine between September 2003 and September 2008. In response to Luke Glanville's reply, this essay identifies further reasons for caution before accepting R2P and so‐called humanitarian wars alongside defensive wars as paradigmatically justified. It is structured with reference to the tests in A More Secure World: Our Shared Responsibility, the Report by the Secretary‐General's High‐level Panel on Threats, Challenges and Change, as recommended to the General Assembly when considering whether to authorize or apply military force: seriousness of risk, intention, last resort, proportional means, balance of consequences.     

The relationship between strategic control and conscious structural knowledge in artificial grammar learning

We address Jacoby’s (1991) proposal that strategic control over knowledge requires conscious awareness of that knowledge. In a two-grammar artificial grammar learning experiment all participants were trained on two grammars, consisting of a regularity in letter sequences, while two other dimensions (colours and fonts) varied randomly. Strategic control was measured as the ability to selectively apply the grammars during classification. For each classification, participants also made a combined judgement of (a) decision strategy and (b) relevant stimulus dimension. Strategic control was found for all types of decision strategy, including trials where participants claimed to lack conscious structural knowledge. However, strong evidence of strategic control only occurred when participants knew or guessed that the letter dimension was relevant, suggesting that strategic control might be associated with – or even causally requires – global awareness of the nature of the rules even though it does not require detailed knowledge of their content.     

The extended ramp model: A biomimetic model of behaviour arbitration for lightweight cognitive architectures

In this article, we present an idea for a more intuitive, low-cost, adjustable mechanism for behaviour control and management. One focus of current development in virtual agents, robotics and digital games is on increasingly complex and realistic systems that more accurately simulate intelligence found in nature. This development introduces a multitude of control parameters creating high computational costs. The resulting complexity limits the applicability of AI systems. One solution to this problem it to focus on smaller, more manageable, and flexible systems which can be simultaneously created, instantiated, and controlled. Here we introduce a biologically inspired systems-engineering approach for enriching behaviour arbitration with a low computational overhead. We focus on an easy way to control the maintenance, inhibition and alternation of high-level behaviours (goals) in cases where static priorities are undesirable. The models we consider here are biomimetic, based on neuro-cognitive research findings from dopaminic cells responsible for controlling goal switching and maintenance in the mammalian brain. The most promising model we find is applicable to selection problems with multiple conflicting goals. It utilizes a ramp function to control the execution and inhibition of behaviours more accurately than previous mechanisms, allowing an additional layer of control on existing behaviour prioritization systems.     

The MMPI-2: A Contemporary Normative Study of Midwestern Family Medicine Outpatients

For more than 60 years it has been known that profiles from the Minnesota Multiphasic Personality Inventory (MMPI), obtained from medical patients, are elevated when scores are plotted using general population norms. These elevations have been most apparent on the neurotic triad (NTd), the first 3 clinical scales on the MMPI profile. More than 45 years have passed since a nonreferred, normative sample of MMPIs was established from 50,000 consecutive medical outpatients. We present comparable but contemporary normative data for the revised MMPI (MMPI-2) based on a nonreferred sample of 1,243 family medicine outpatients (590 women; 653 men). As true for the original MMPI, contemporary medical outpatients have profiles that are significantly different, clinically and statistically, from the general population norms for the MMPI-2. This is particularly evident in elevations on the NTd. New normative tables of uniform medical T (UMT) scores were developed following the procedures used to create the uniform T scores for the MMPI-2. Measures of internal consistency are reported; test-retest reliability was established over a mean of 3.7 weeks, and results characterizing the stability of the validity and clinical scales are presented.     

Transgenic inhibition of neuronal calcineurin activity in the forebrain facilitates fear conditioning, but inhibits the extinction of contextual fear memories

It is unclear whether protein phosphatases, which counteract the actions of protein kinases, play a beneficial role in the formation and extinction of previously acquired fear memories. In this study, we investigated the role of the calcium/calmodulin dependent phosphatase 2B, also known as calcineurin (CaN) in the formation of contextual fear memory and extinction of previously acquired contextual fear. We used a temporally regulated transgenic approach, that allowed us to selectively inhibit neuronal CaN activity in the forebrain either during conditioning or only during extinction training leaving the conditioning undisturbed. Reducing CaN activity through the expression of a CaN inhibitor facilitated contextual fear conditioning, while it impaired the extinction of previously formed contextual fear memory. These findings give the first genetic evidence that neuronal CaN plays an opposite role in the formation of contextual fear memories and the extinction of previously formed contextual fear memories.

从2型糖尿病的发病机制谈糖尿病治疗的新策略

2型糖尿病的发病机制主要为胰岛素抵抗与胰岛β细胞分泌功能受损,二者相互依存、相互作用。2型糖尿病的治疗应以减轻胰岛素的抵抗和保护胰岛β细胞为主,以生活方式干预加二甲双胍作为基础治疗,根据不同个体在不同阶段所侧重的不同发病机制,采用联合、综合管理。     

不同认知方式个体图形一致性判断过程中的ERP研究

使用ERP技术对选取的27名右利手大学生（场独立14名,场依存13名）在图形一致性判断过程中的ERP进行分析,结果表明：1）在图形一致性的判断任务中,场依存者的前额叶与中央区在200ms之前的N85与P160峰-峰之差明显大于场独立者,在枕叶区的负波N120波幅明显高于场独立者,这说明场依存者在对图形一致性比较的视觉信息处理的早期阶段即进行了更深度的加工。2）场独立者的N290波幅高于场依存者,而N290潜伏期比场依存者明显的长,这说明场独立者在后期对图形进行了更深入的分析比对。     

RATS,We Should Have Used Clinton: Subliminal Priming in Political Campaigns

Political strategists decide daily how to market their candidates. Growing recognition of the importance of implicit processes (processes occurring outside of awareness) suggests limitations to focus groups and polling, which rely on conscious self‐report. Two experiments, inspired by national political campaigns, employed Internet‐presented subliminal primes to study evaluations of politicians. In Experiment 1, the subliminal word “RATS” increased negative ratings of an unknown politician. In Experiment 2, conducted during former California Governor Gray Davis's recall referendum, a subliminal photo of Clinton affected ratings of Davis, primarily among Independents. Results showed that subliminal stimuli can affect ratings of well‐known as well as unknown politicians. Further, subliminal studies can be conducted in a mass media outlet (the Internet) in real time and supplement voter self‐report, supporting the potential utility of implicit measures for campaign decision making.     

Individual strategy preferences and decisional fit

The present research introduces the concept of decisional fit. A decision maker experiences decisional fit when the individually preferred decision strategy fits the actually applied strategy. In accordance to other fit‐concepts in psychology (e.g., person–environment fit), we expected positive effects of decisional fit. Five studies examine the effects of a fit between the individual preference for intuition and deliberation (PID) and the actually used decision strategy (intuition or deliberation). A comparison of extreme types (according to participants' values on the PID scale) revealed that decisional fit enhances the perceived value of the chosen or evaluated object (Studies 1–3). In Studies 4 and 5, participants experienced less regret after decisional fit. The findings highlight the importance of considering individual differences when comparing intuitive and deliberate decision making, because strategy preferences interact with applied strategies.
