No Matrix Term-Equivalent to Wroński's 3-element Matrix is Finitely Based

Motivated by a question of W. Rautenberg, we prove that any matrix that is term-equivalent to the well-known nonfinitely based matrix of A. Wroski is itself also nonfinitely based.     

Placebo in the investigation of psychotropic drugs,especially antidepressants

The paper presents major ethical, legal and methodological problems related to the use of placebo in mental disorders, especially in depression. It is pointed out that although authoritative groups of experts and numerous publications in the field of psychopharmacology indicate advisability of the double blind design with placebo in clinical trials of antidepressants, in recent years there have been more and more voices questioning legitimacy of this method. Objections of an ethical nature are raised, and reliability of this approach is put into doubt from the methodological viewpoint. These issues are discussed in more detail in the paper. Available alternative solutions should be implemented in psychotropic drug studies. The author shares these objections and doubts of an ethical nature, and believes that the placebo procedure is not a necessity in clinical trials of antidepressants. An earlier version of this paper was presented at an international conference, “Placebo: Its Action and Place in Health Research Today,” held in Warsaw, Poland on 12–13 April, 2003.     

The concept of quality in clinical research

Quality in clinical research may be defined as compliance with requirements together with credibility and reliability of the data obtained. Sponsors usually apply Quality Management Systems (QMS) to ensure, control, maintain, and improve quality. These systems encompass several preventive measures, tools, and controls. Standard QMS applied by clinical research sponsors may be based on ISO 9000. An earlier version of the paper was presented at the 6th International Bioethics Conference on the subject of ‘The Responsible Conduct of Basic and Clinical Research’, held in Warsaw, Poland, 3–4 June 2005.     

Obedience to authorities is not unconditional: Differential effects of COVID-19 threat on three facets of RWA in Poland and Germany

Collective authoritarian responses to threat might differ depending on whether people trust collective authorities in reducing threat. Thus, we tested the differential effects of epidemic threat on three facets of right-wing authoritarianism, in Germany (a country with high authorities' efficacy in responses to COVID-19) and Poland (low authorities' efficacy context). Two representative sample longitudinal studies performed in Poland (N = 892) and Germany (N = 883) showed that in Germany feelings of COVID-19 threat explained increases in authoritarian submission and (to a lesser extent) authoritarian aggression, whereas in Poland such feelings of threat explained changes in authoritarian aggression and conventionalism after the pandemic, but did not alter authoritarian submission. These findings suggest that specific authoritarian reactions to threat (submissive vs. conventionalist) might depend on the general trust in authorities' ability to respond to crises.

Self-Talk: Conversation With Oneself? On the Types of Internal Interlocutors

The two studies presented in the article aimed to empirically verify the tentative typology of internal interlocutors in self-talk proposed in a previous research project. The typology comprised four emotional types: Faithful Friend, Ambivalent Parent, Proud Rival, and Helpless Child. Study 1 involved 98 participants (49 women) and Study 2 involved 114 (55 women), mostly students. In both studies, the names of internal interlocutors were generated by participants as qualitative data, quantified by reference to the standard set of affect terms, and, as affective patterns, subjected to clustering. Study 2 fully confirmed the recent results, whereas Study 1 revealed a new interlocutor type instead of Helpless Child – Calm Optimist. The conducted studies confirm the existence of four main types of inner interlocutors and provide a reason to verify the existence of Calm Optimist.     

Determinants of Integration and Confrontation in Internal Dialogues

Interest in the distinction between integrative and confrontational internal dialogues has been growing, as research suggests numerous positive functions of the former compared to the latter. The article proposes a theoretical approach to integration and confrontation in internal dialogue and an empirical method of measuring these processes. Exploratory research is also presented that seeks to identify personality‐related and situational determinants of integration and confrontation in internal dialogue simulating social relationships. Canonical correlation analysis did not establish personality determinants but it did reveal situational determinants (understood as cognitive interpretation of the enacted situation) behind integration and confrontation in internal dialogue. Perceiving the internal interlocutor as similar to the dialogue's author is associated with the author's integrative attitude. An increase in the wishfulness of the dialogue is accompanied by an increase in the author's confrontational attitude and the interlocutor's integrative attitude.     

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.
