AbstractThis study examines the relations among style and development level of four interpersonal and intrapsychic processes: interpersonal thought, self-reported interpersonal action, mechanisms of defense, and object representation. Subjects were 25 girls and 25 boys from the eighth grade of an urban public school System. All four constructs were measured along developmental and stylistic dimensions. Both interpersonal thought and self-reported action processes were measured with the hypothetical and real-life interpersonal negotiation strategies interviews of Selman and colleagues. Defensive process was measured with a questionnaire revised to include Vaillant's developmental analysis of defense mechanisms as well as assessment of style of defense (internalizing vs. externalizing). Object representation style and level were measured with constructs and instruments of Blatt and colleagues. The results supported the main hypothesis: Levels of defense mechanisms and object representation independently predicted level of self-reported interpersonal action, even when controlling for level of interpersonal thought (which also predicted action). This suggests that if there are gaps between interpersonal thought and action levels, the relative level of maturity of psychodynamic processes helps explain action level. In contrast, there were few relationships among the stylistic components of the four constructs, although each style construct was related to its associated level construct. Contrary to hypotheses, no gender differences were found on any of the composited level or style variables. The study suggests operational links between structural-developmental and psychodynamic aspects of personality.

Image Organization

This is a preprint. Please find the published and peer reviewed version of the paper here: https://www.journalofcognition.org/articles/10.5334/joc.80/. Images differ in their intrinsic memorability. The factors driving image memorability are not fully understood. Here, we hypothesized that memorability at least partly depends on goodness of image organization. Good organizations have been associated with fast, efficient processing and robustness against transformation (e.g., shrinking). Based on the main hypothesis, these characteristics would then also pertain to memorable images. Study 1 focused on fast processing and predicted that memorable images are easier to categorize rapidly, while Study 2 predicted that they survive a shrinking transformation better. We used real-life scene images of 14 semantic categories from a previous memorability study. Each image was assigned a “categorizability” and “shrinkability” score based on the average performance across participants on a rapid-scene categorization task (Study 1) and a thumbnail search task (Study 2), respectively. The predicted positive relation between categorizability and memorability was not observed. A post-hoc explanation attributed this null result to a masking role of image distinctiveness. In the thumbnail search task, memorable images were located faster, as predicted, but Study 2 could not rule out that this was merely a result of their distinctiveness. A third study quantified the images on distinctiveness and statistically controlled for this variable in a reanalysis of Study 1 and Study 2. When distinctiveness was controlled for, categorizability and memorability did show a significant positive correlation. Moreover, the results also argued against the alternative explanation of the results of Study 2. Taken together, the results support the hypothesis that goodness of organization contributes to image memorability.

In the anarchism that governs the nature and patterns of international relations characterized by instability and uncertainty in light of several changes, as well as the information revolution and the resulting developments and qualitative breakthroughs in the field of scientific and advanced technological knowledge and modern technologies.  All of these variables pushed toward the information flow and flow tremendously, so rationality became an indispensable matter for the decision maker as he faces these developments and changes. There must be awareness and rationality in any activity or behavior because it includes choosing the best alternative and making the right decision and selecting the information accurately and mental processing Through a mental system based on objectivity, methodology, and accumulated experience away from idealism and imagination, where irrationality and anarchy are a reflection of the fragility of the decision-maker, his lack of awareness of the subject matter, his irresponsibility, and recklessness that inevitably leads to failure by wasting time and Effort and potential. The topic acquires its importance from a search in the strategies of the frivolous state and its characteristics with the ability to influence the regional, and what it revealed is a turning point in how to adapt from the variables and employ them to their advantage and try to prove their existence. Thus, the problem comes in the form of a question about the possibility of the frivolous state in light of the context of various regional and international events and trends. The answer to this question stems from the main hypothesis that (the aim which the frustrating state seeks to prove is that it finds itself compelled to choose several strategies that start from the nature of its characteristics and the goals that aim at it, which are centered in the circle of its interests in the field of its struggle for the sake of its survival and area of influence).

Reactive oxygen species (ROS) comprise the superoxide anion (O2·−), hydrogen peroxide (H2O2), hydroxyl radical (·OH), and singlet oxygen (1O2). ROS can damage a variety of macromolecules, including DNA, RNA, proteins, and lipids, and compromise cell viability. To prevent or reduce ROS-induced oxidative stress, bacteria utilize different ROS defense mechanisms, of which ROS scavenging enzymes, such as superoxide dismutases, catalases, and peroxidases, are the best characterized. Recently, evidence has been accumulating that some of the terminal oxidases in bacterial respiratory chains may also play a protective role against ROS. The present review covers this role of terminal oxidases in light of recent findings.

The CreditRisk+ model is one of the industry standards for the valuation of default risk in credit loans portfolios. The calibration of CreditRisk+ requires, inter alia, the specification of the parameters describing the structure of dependence among default events. This work addresses the calibration of these parameters. In particular, we study the dependence of the calibration procedure on the sampling period of the default rate time series, that might be different from the time horizon onto which the model is used for forecasting, as it is often the case in real life applications. The case of autocorrelated time series and the role of the statistical error as a function of the time series period are also discussed. The findings of the proposed calibration technique are illustrated with the support of an application to real data.

AbstractIn the absence of any neuropsychiatric condition, older adults may show declining performance in several cognitive processes and among them, in retrieving and producing words, reflected in slower responses and even reduced accuracy compared to younger adults. To overcome this difficulty, healthy older adults implement compensatory strategies, which are the focus of this paper. We provide a review of mainstream findings on deficient mechanisms and possible neurocognitive strategies used by older adults to overcome the deleterious effects of age on lexical production. Moreover, we present findings on genetic and lifestyle factors that might either be protective or risk factors of cognitive impairment in advanced age. We propose that “aging-modulating factors” (AMF) can be modified, offering prevention opportunities against aging effects. Based on our review and this proposition, we introduce an integrative neurocognitive model of mechanisms and compensatory strategies for lexical production in older adults (entitled Lexical Access and Retrieval in Aging, LARA). The main hypothesis defended in LARA is that cognitive aging evolves heterogeneously and involves complementary domain-general and domain-specific mechanisms, with substantial inter-individual variability, reflected at behavioral, cognitive, and brain levels. Furthermore, we argue that the ability to compensate for the effect of cognitive aging depends on the amount of reserve specific to each individual which is, in turn, modulated by the AMF. Our conclusion is that a variety of mechanisms and compensatory strategies coexist in the same individual to oppose the effect of age. The role of reserve is pivotal for a successful coping with age-related changes and future research should continue to explore the modulating role of AMF.

AbstractLearning is a complex phenomenon. Contemporary theories of education underline active participation of learners in their learning processes. One of the key arguments supporting this approach is the learner’s simultaneous and unconscious development of their ability of “learning to learn”. This ability belongs to the soft skills highly valued by employers today.For Mathematics Education, it means that teachers have to go beyond making calculations and memorizing formulas. We have to teach the subject in its social context. When the students start understanding the relationship between real-life problems and the role of numbers and formulas for their solutions, their learning becomes a part of their tacit knowledge. Below we explain the theoretical background of our approach and provide examples of such activities.

Effects Of Drought

In recent years, research on spermine (Spm) has turned up a lot of new information about this essential polyamine, especially as it is able to counteract damage from abiotic stresses. Spm has been shown to protect plants from a variety of environmental insults, but whether it can prevent the adverse effects of drought has not yet been reported. Drought stress increases endogenous Spm in plants and exogenous application of Spm improves the plants’ ability to tolerate drought stress. Spm’s role in enhancing antioxidant defense mechanisms, glyoxalase systems, methylglyoxal (MG) detoxification, and creating tolerance for drought-induced oxidative stress is well documented in plants. However, the influences of enzyme activity and osmoregulation on Spm biosynthesis and metabolism are variable. Spm interacts with other molecules like nitric oxide (NO) and phytohormones such as abscisic acid, salicylic acid, brassinosteroids, and ethylene, to coordinate the reactions necessary for developing drought tolerance. This review focuses on the role of Spm in plants under severe drought stress. We have proposed models to explain how Spm interacts with existing defense mechanisms in plants to improve drought tolerance.

The Subject

Selenium (Se) is an important trace mineral having many essential roles at the cellular and organismal levels in animal and human health. The biological effects of Se are mainly carried out by selenoproteins (encoded by 25 genes in humans and 24 in mice). As an essential component of selenoproteins, Se performs structural and enzymic roles; in the latter context it is well known for its catalytic and antioxidative functions. Studies involving different animal models have added great value to our understanding regarding the potential implications of Se and selenoproteins in mammalian fertility and reproduction. In this review, we highlight the implications of selenoproteins in male fertility and reproduction followed by the characteristic biological functions of Se and selenoproteins associated with overall male reproductive function. It is evident from observations of past studies (both animal and human) that Se is essentially required for spermatogenesis and male fertility, presumably because of its vital role in modulation of antioxidant defense mechanisms and other essential biological pathways and redox sensitive transcription factors. However, bearing in mind the evidences from mainstream literature, it is also advisable to perform more studies focusing on the elucidation of additional roles played by the peculiar and canonical selenoproteins i.e., glutathione peroxidase 4 (GPX4) and selenoprotein P (SELENOP) in the male reproductive functions. Nevertheless, search for the elucidation of additional putative mechanisms potentially modulated by other biologically relevant selenoproteins should also be included in the scope of future studies. However, as for the implication of Se in fertility and reproduction in men, though a few clinical trials explore the effects of Se supplementation on male fertility, due to inconsistencies in the recruitment of subjects and heterogeneity of designs, the comparison of such studies is still complicated and less clear. Therefore, further research focused on the roles of Se and selenoproteins is awaited for validating the evidences at hand and outlining any therapeutic schemes intended for improving male fertility. As such, new dimensions could be added to the subject of male fertility and Se supplementation.

Artistic Training

In seventeenth-century Holland, the role of the live model in the making of art and, importantly, as a vehicle for artistic training had become a topic of contention. No other aspect of artists’ education had received more criticism than the use of real-life models. Artists ran the risk of drawing too much attention to the live model, leaving the model’s features visible in their works. These works would look too much like life itself. This essay argues that seventeenth-century theorists devised an intricate concept of style in order to keep life in an artwork at bay. To train artists was to discipline them in style.
