Cancer patients in young adulthood are affected by the cancer diagnosis in a period of life where future parenthood or fulfilling of a potential wish to have children plays an important role. To perform fertility preserving treatment, patients should be fully informed before any treatment is carried out. The following review broaches the issue of whether and how fertility concerns are discussed in the medical consultation. Therefore, relevant papers were identified by a database search between the years 2000 and 2010. A total of 21 studies were included which focussed on physician-patient communication from the point of view of the patients or healthcare professionals. Oncologists do not routinely speak to patients about fertility issues. Both oncologists and patients expressed communication difficulties. An improvement of the medical interview concerning family planning could be achieved by provision of guidelines, training for healthcare professionals, cooperation between oncologists and reproductive medicine and the provision of educational patient material. 相似文献

This study explored the similarity of underlying personality traits of workplace bullying and discrimination. University students self-reported the frequency of bullying others in the workplace and discriminating against African Americans, homosexuals, and the obese. They completed questionnaires measuring prejudice and personality traits. The major findings were that social dominance orientation, low social desirability scores, and being male affected bullying and discrimination. Perspective taking affected bullying; and right-wing authoritarianism, anxiety, and being White affected discrimination. Prejudice influenced relations between personality and discrimination, but not bullying. It was concluded that despite strong behavioral similarities, bullying and discrimination have somewhat different underlying determinants. Certain traits make them distinct, increasing the likelihood of one choosing either a prejudice-based target or a non-prejudice-based target. 相似文献

The influence of stress on cardiac electrical stability (CES) and chaotic dynamics of the electrical activity of the heart was studied in acute and chronic experiments in rabbits. Stress was caused by 2-3 h daily immobilization of the animals with electrical stimulation of emotiogenic centers of the hypothalamus through implanted electrodes. CES was estimated by the thresholds for ventricular arrhythmia: paroxysmal ventricular tachycardia, repeated ventricular extrasystoles and ventricular fibrillation (VF). The results showed: (i) CES in stressed rabbits was decreased significantly compared with controls; (ii) the level of chaos at the onset of VF in stressed rabbits was increased significantly compared with controls; (iii) heart rate of stressed rabbits was significantly greater than in controls; (iv) changes in CES parameters depended on whether stress was acute or chronic; (v) acute stress promoted transition of spontaneously reversible VF into spontaneously irreversible VF. Thus, stress increased the degree of disorganization of heart electrical activity and also decreased its electrical stability. The experiments indicate that stress is a destabilizing factor influencing the reversibility of heart rate disorders. The probability of such reversibility depends on whether stress is acute or chronic: acute stress is more likely to lead to irreversible spontaneous VF. 相似文献

Auditory perception of the depth of space is based mainly on spectral and amplitude changes of sound waves originating from the sound source and reaching the listener. The perceptive illusion of movement of an auditory image caused by changes in amplitude and/or frequency of the signal tone emanating from an immobile loudspeaker was studied. Analysis of data obtained from the participants revealed the diapason of combinations of amplitude and frequency changes for which the movement direction was perceived similarly by all participants, despite significantly different movement assessment criteria. Additional auditory and visual information of the conditions of radial movement (near or far fields) determined listeners' interpretation of changes in the signal parameters. The data obtained about the perception of approach and withdrawal models are evidence of the fact that the principal cues of the perception of the distance of immobile sound sources manifests similarly to that of an auditory image moving along a radial axis. 相似文献

The concept of regression is considered with an emphasis on the differences between the positions of Freud and Jung regarding its significance. The paper discusses the results of experimental analyses of individual experience dynamics (from gene expression changes and impulse neuronal activity in animals to prosocial behaviour in healthy humans at different ages, and humans in chronic pain) in those situations where regression occurs: stress, disease, learning, highly emotional states and alcohol intoxication. Common mechanisms of regression in all these situations are proposed. The mechanisms of regression can be described as reversible dedifferentiation, which is understood as a relative increase of the representation of low-differentiated (older) systems in the actualized experience. In all of the cases of dedifferentiation mentioned above, the complexity of the systemic organization of behaviour significantly decreases. 相似文献

N‐Methyl‐D ‐aspartate (NMDA) receptor antagonists are perspective candidates for medication development for a number of diseases/states that are associated with increased aggressiveness (e.g., opioid withdrawal). The prototypic NMDA receptor antagonist phencyclidine (PCP) itself is a widely abused substance and is known to elevate levels of aggression in drug users. The present study was aimed at testing several drugs that share with PCP the ability to block NMDA receptor–associated channel. The resident‐intruder procedure was used to assess drug effects on aggressive behavior in isolated male mice. Resident aggressive mice were administered NMDA channel blockers (PCP; 0.3–10 mg/kg), dizocilpine (MK‐801; 0.01–0.3 mg/kg), memantine (1–30 mg/kg), and MRZ 2/579 (0.1–5.6 mg/kg). The competitive NMDA receptor antagonist D CPPene (0.1–5.6 mg/kg) was also tested as a compound representing an alternative approach to reduce activity of NMDA receptor complex. PCP, dizocilpine, and memantine inhibited expression of aggressive behaviors only at doses that produced ataxia. The novel channel blocker MRZ 2/579 also produced ataxia at the highest dose level but failed to affect aggressiveness. Reduction in aggression with a corresponding increase in sociability was observed after administration of D ‐CPPene. Overall, the present results suggest that NMDA receptor channel blockers do not exert selective effects on aggressive behavior. Aggr. Behav. 25:381–396, 1999. © 1999 Wiley‐Liss, Inc. 相似文献

Parents' values for their children and their beliefs about appropriate child‐rearing practices contribute to the ways in which they try to shape their children's development. This paper examines the values and beliefs of 71 parents (37 mothers and 34 fathers) from two cities in the United States and Russia. Half of the families were middle class (determined by education and occupation criteria) and half were working class. The results revealed no cross‐societal differences in value for self‐direction in the children; perhaps reflecting the recent economic and ideological changes in Russia. In contrast, significant social class differences, for both mothers and fathers, were found in child‐rearing values and beliefs. Middle class parents in both societies were more likely to value self‐direction and believe that children should have freedom in and around the home, whereas working class parents were more likely to believe that children should be expected to conform to rules. The results of this study underscore the role of within‐society heterogeneity, as a function of social class, in parents' values and beliefs about child‐rearing. 相似文献

This paper investigates the role of pictures in mathematics in the particular case of Cayley graphs—the graphic representations
of groups. I shall argue that their principal function in that theory—to provide insight into the abstract structure of groups—is
performed employing their visual aspect. I suggest that the application of a visual graph theory in the purely non-visual
theory of groups resulted in a new effective approach in which pictures have an essential role. Cayley graphs were initially
developed as exact mathematical constructions. Therefore, they are legitimate components of the theory (combinatorial and
geometric group theory) and the pictures of Cayley graphs are a part of practical mathematical procedures. 相似文献

The horrific terrorist attacks on the United States on September 11, 2001, left an indelible mark on perceptions of security and threat across the world. This paper uses Schwartz's (1992) value circumplex model to examine value change across matched high school and university student samples in Finland, questioned before and after the World Trade Center (WTC) and associated attacks. In Study 1 ( N =419), security values of adolescents were higher the day following the WTC attacks than before, but fell back toward pre-attack levels in the subsequent two samples. In contrast, levels of stimulation were lower following the terrorist incidents. In Study 2 ( N =222), security levels of students were also higher following the WTC attacks, but again were closer to pre-attack levels in a subsequent cohort. 相似文献
