On the Logic of β-pregroups

In this paper we concentrate mainly on the notion of β-pregroups, which are pregroups (first introduced by Lambek [18] in 1999) enriched with modality operators. β-pregroups were first proposed by Fadda [11] in 2001. The motivation to introduce them was to limit (locally) the associativity in the calculus considered. In this paper we present this new calculus in the form of a rewriting system, prove the very important feature of this system - that in a given derivation the non-expanding rules must always proceed non-contracting ones in order the derivation to be minimal (normalization theorem). We also propose a sequent system for this calculus and prove the cut elimination theorem for it. As an illustration we show how to use β-pregroups for linguistical applications.

Assessing inhibitory control in early-stage Alzheimer's and Parkinson's disease using the Hayling Sentence Completion Test

The ability to inhibit irrelevant information is essential for coping with the demands of everyday life. Inhibitory deficits are present in all stages of dementia and commonly observed in people with Parkinson's disease (PwPD). Inhibition is frequently tested with the Stroop test, but this may lack ecological validity. This study investigates inhibitory control in people with Alzheimer's disease dementia (PwD) and PwPD using the Hayling Sentence Completion Test (HSCT), which aspires to be a more ecologically valid task. A total of 117 people completed the HSCT, a test where participants have to complete a sentence with an unrelated word. The sample comprised 30 PwD, 33 PwPD, and 54 healthy older controls. We compared response times and the number and type of errors across the three groups. Completion time in Part B (Inhibition) did not distinguish between PwD, PwPD, and controls when controlling for the initiation speed, but a higher proportion of Category A errors (producing a word that fits the sentence when instructed otherwise) was a unique characteristic of inferior performance in PwD and PwPD. While not part of the standard test scoring protocol, controlling for the initiation speed and distinguishing between speed and accuracy in test performance appear to be essential for accurate evaluation of the inhibitory control in HSCT in older people. The findings suggest that the HSCT may be sensitive to verbal suppression deficits and may provide insight into inhibitory control in PwD and PwPD.     

The Default Position: Optimizing Pediatric Participation in Medical Decision Making

Inclusion of children in medical decision making, to the extent of their ability and interest in doing so, should be the default position, ensuring that children are routinely given a voice. However, optimizing the involvement of children in their health care decisions remains challenging for clinicians. Missing from the literature is a stepwise approach to assessing when and how a child should be included in medical decision making. We propose a systematic approach for doing so, and we apply this approach in a discussion of two challenging clinical cases. The approach is informed by a literature review, and is anchored by case studies of teenagers' refusal of clinical care, regulatory requirements for research assent, and the accepted approach to involving cognitively impaired adults in medical decisions.     

Addicted to answers: Need for cognitive closure and the endorsement of conspiracy beliefs

Conspiracy theories offer simple answers to complex problems by providing explanations for uncertain situations. Thus, they should be attractive to individuals who are intolerant of uncertainty and seek cognitive closure. We hypothesized that need for cognitive closure (NFCC) should foster conspiracy beliefs about events that lack clear official explanations, especially when conspiracy theories are temporarily salient. In Experiment 1, NFCC positively predicted the endorsement of a conspiracy theory behind the refugee crisis, especially when conspiratorial explanations were made salient. Experiment 2 showed that when conspiratorial explanations were made salient, NFCC positively predicted beliefs in conspiracies behind a mysterious plane crash. However, the link between NFCC and beliefs in conspiratorial explanations was reversed in the case of a plane crash with an official, non‐conspiratorial, explanation for the accident. In conclusion, people high (vs. low) in NFCC seize on conspiratorial explanations for uncertain events when such explanations are situationally accessible.     

Feeling Hopeful Inspires Support for Social Change

Hope is an emotion that has been implicated in social change efforts, yet little research has examined whether feeling hopeful actually motivates support for social change. Study 1 (N = 274) confirmed that hope is associated with greater support for social change in two countries with different political contexts. Study 2 (N = 165) revealed that hope predicts support for social change over and above other emotions often investigated in collective action research. Study 3 (N = 100) replicated this finding using a hope scale and showed the effect occurs independent of positive mood. Study 4 (N = 58) demonstrated experimentally that hope motivates support for social change. In all four studies, the effect of hope was mediated by perceived efficacy to achieve social equality. This research confirms the motivating potential of hope and illustrates the power of this emotion in generating social change.     

Clients’ Perception of Outcome of Team-Based Prenatal and Reproductive Genetic Counseling in Serbian Service Using the Perceived Personal Control (PPC) Questionnaire

This is the first study in Serbia and the region of South-East Europe dedicated to clients’ perception of outcome and efficiency of prenatal and reproductive genetic counseling. The primary aim of this study was to assess overall value and success of genetic counseling in prenatal and reproductive care with regard to perceived personal control of clients, reflecting also in a part patient comprehension, knowledge retention, and empowerment in decision-making. The standardized Perceived Personal Control questionnaire (PPC) was used for the assessment of 239 female participants. First, we performed a complete validation of the psychometric characteristics of the Serbian-language version of the PPC questionnaire. The validation of the questionnaire permits other researchers from Serbian-speaking regions of South-East Europe to use this standard instrument to assess the effectiveness of prenatal genetic counseling in their communities and analyze advantages and disadvantages of their counseling models. We also measured social and demographic characteristics of participants. Further, we analyzed effects of our team-based prenatal and reproductive genetic counseling model through (a) calculation of PPC scores at three different stages (before initial, after initial, and before second counseling session), and (b) by assessing participants’ responses by indication for referral (advanced maternal age, abnormal biochemical screening, family history of hereditary disorders, maternal exposure to drugs, exposure to radiation, exposure to infective agents, infertility or recurrent abortions, and miscellaneous). The results indicate that participants’ knowledge after initial counseling increased significantly and after that remained stable and sustainable. A satisfactory level of confidence among participants had been achieved, in that many felt an increased sense of control over their situation and emotional response to it. Indirectly, these results indicate the success of a team-based prenatal genetic counseling model, which has not been assessed in the literature to date.     

The role of social support in women’s health and recovery processes

The aim of this study was to assess the psychological state of women who have undergone surgery for breast cancer or cardiac surgery, including examination of the role of social support in both groups. The study included 48 women (mean age: 66.04?±?8.3 years). They were divided into two groups according to diagnosis: 23 women (mean age: 69.2?±?8.6 years) who underwent heart surgery (cardiac group, CG) and 25 women (mean age: 63.2?±?7.0 years) treated for breast cancer and associated with the Women After Mastectomy Club (oncology group, OG). In addition to the assessment of socio-demographic variables, the following self-report questionnaires were administered: Satisfaction with Life Scale, Acceptance of Illness Scale, Beck Depression Inventory, Spielberger State-Trait Anxiety Inventory as well as Berlin Social Support Scale. In the CG, the severity of depressive symptoms was two times higher than in OG (p?=?.003). In both groups, there was a high percentage (80%) of women with severe symptoms of anxiety (p?=?.37). In both groups, the level of life satisfaction was similar (p?=?.58), but OG was characterized by a higher level of acceptance of the disease (p?=?.003). The correlation analysis showed that in both groups, social support was related differently to the parameters of emotional state. Women treated for breast cancer were in a better mental condition than women treated for heart disease. The support coming from other women in similar circumstances (Women After Mastectomy Club) seems to be more effective than the support coming from the patient’s immediate environment. The results for social support ought to be interpreted not only through the prism of mean values of received support, but also with regard to the information on the sources of support.     

Definitions need to be precise and consistent: A reply to Haslam with suggestions for the future

In his reply to our critique of research on self-humanizing, Haslam claims that we used a narrow definition of self-humanizing that ignored the evidence from the correlational research he and his colleagues have done. We disagree. First, we relied upon a definition of self-humanizing based upon comparative judgments that Haslam and colleagues have consistently used. Second, we were well aware of the correlational research he and his colleagues have done. We simply did not think, and do not think, these correlations verified the existence of self-humanizing as defined. In his reply, Haslam offered a new definition of self-humanizing that defines self-humanizing in terms of correlations between comparative judgments and ratings of how much traits reflect human nature. Although we believe this change represents some progress, numerous issues in the study of self-humanizing remain to be resolved. We offer some suggestions for future research on this important topic.     

Binge drinking and violence against intimate partners in Russia

This study is the first to provide information on the association between intimate partner violence (IPV) and binge drinking among Russian university students. Using data from 500 (58% female) university students from the four Russian sites of the International Dating Violence Study, we found gender differences in rates of IPV perpetration and in the association between binge drinking and IPV. Specifically, more females than males perpetrated IPV, and the associations between binge drinking and IPV were stronger for the female students than for the male students. In addition, antisocial traits and behavior (ATSB) were significantly related to both binge drinking and IPV perpetration for males and females. For males, the relatively weak associations between binge drinking and IPV perpetration disappeared once ASTB was accounted for. For females, the relationship decreased but remained significant when ATSB was statistically controlled. Path analyses confirmed that this pattern of relationships would be consistent with ATSB serving as a partial mediator between binge drinking and IPV perpetration. However, other alternative mediation and moderation models for the relationships between binge drinking, IPV perpetration, and ATSB could not be ruled out with this one-wave correlational study.
