Insight Into

A longer exposure time generally improves individuals’ ability to recognize faces. The current research investigates whether this effect varies between genders and whether it is influenced by the gender of the exposed faces. Based on a set of four experimental studies, we advance our knowledge of face recognition, gender, gender distribution of exposed faces, and exposure time in three main ways. First, the results reveal that women are more likely than men to suffer from a decrease in face recognition ability due to a lower exposure time. Second, the findings show that when exposure time is short (vs. long) women recognize a larger proportion of same gender faces and also recognize a larger proportion of same gender faces as compared with the proportion of same gender faces recognized by men. Third, findings reveal that when individuals are only exposed to same gender faces, women recognize more faces than men regardless whether exposure time is short, or long. In short, the findings of this research suggest that insight into the interplay between gender and exposure time length is critical to appropriately determine human beings’ ability to recognize faces.

Artistic commemoration of leaders and other iconic personalities has been in existence for centuries. Statues in particular have been used as a fitting avenue for the commemoration of political leaders and other luminaries in many fields. The premise upon which statues are made is that the subjects featured initiated and attained, in their lifetimes, concrete achievements that significantly impacted upon the lives of their fellow human beings. Other criteria for commemoration include proven integrity, dedication and selflessness in the service of the country and citizens. Statues as an integral part of public art have often generated substantial controversy on various fronts in many countries. Some of these gravitate around issues such as disputed likeness, queries about the fundamental achievements cited of the subject, at times open protests on the actions, character and integrity of the subject as well as the location of the statues. Other areas of contention include the implication of the presence of statues upon the political psyche of the country and their long-time impact on history, the youth and posterity. This paper examines the extent to which African countries have embraced this mode of artistic rendition to commemorate African political leaders in a way that is commensurate to their achievements. It is outside the scope of this paper to delve into the intricate web of back-and-forth arguments about the ‘concreteness’ of the legacies of the featured leaders who are mainly founding political figures of the respective countries. The paper, however, analyses the artistic essence of the selected statues in terms of their visual impact and whether they are indeed useful in articulating the legacies of the subjects and further, whether they ultimately bear ‘enduring visual value’ that spurs conversation and insight into these legacies. Statues must, at the very least, spur debate and conversation into the legacy of the featured subject. It becomes a form of constant interrogation as history itself takes its course; controversy is not necessarily a negative occurrence since it forms part of this discourse. The concept of immortalization, which is what initiators of statues often hope for is much harder to achieve and difficult to define. The paper examines 20 statues of African political leaders in different African Countries.

ABSTRACT Microflora can be found in both caries-free and periodontitis-free people and caries-affected and periodontitis-affected people, and many clinical studies reveal that the portion of certain bacterial species such as Streptococcus mutans or Porphyromonas gingivalis, respectively, is increased in patients with caries or periodontitis. Therefore, it seems that the competition that results between beneficial bacteria and virulent bacteria leads to either a healthy or sick status of human beings. Competition between members of the dental microflora and there role in pocket recolonization is very complex and many antagonistic characteristics can be observed from competition for initial attachment on tooth surfaces or for later attachment to pioneer bacteria, competition from bacteriocins or hydrogen peroxide secreted and from facilitating the growth of some species which inhibit other species. To date only some of the details of these mechanisms are known. The present review will provide an overview on the prevalence of beneficial bacteria and the major mechanisms of oral bacterial interactions. Due to the large number of oral bacterial species, only the best characterized species are included in this review.

Neuroscience offers insight into processes that support the development of the social brain within the cultural contexts that permit attachment relationships to form. Both human and nonhuman animal studies are critical to inform theory development and hypothesis testing via descriptive and experimental studies. A scientifically valid evolutionary theory is necessary to account for the remarkable diversity of parenting systems across human and many nonhuman animals. This chapter examines the neural foundations of attachment and poses critical questions that relate to the initiation of this relationship: How does attachment interface with brain development? What is the interplay between attachment and brain development (including elements of bidirectionality)? Are there negative consequences associated with variation in attachment, and are they reversible? Rather than conceptualizing attachment in terms of a single type of relationship, or a rigid developmental channel, this chapter proposes that an expanded consideration of variation is necessary to understand the neural foundations of infant-caregiver relationships, and the role of those relationships in developing competence across the life span. This approach will permit identification of common neurobiological elements of attachment as well as the remarkable plasticity and diversity within and across individuals, cultures, and species.

Purpose Some marketers have challenged psychologists’ contention that human beings can only learn by using conscious effort. They argue that advertising can be effective at low levels of (or even no) attention. Also, despite the absence of (or low levels of) consciousness, these subconscious responses can be linked to brands. The purpose of this study is to investigate the impact of implicit learning in the context of logo substitution – an image that may not look like the original logo, and may not even be consciously associated with the original brand or its logo. Design/methodology/approach Data were collected by means of two quasi-experimental studies. Findings The results suggest that, thanks to implicit learning, logo substitution can be effective. Research limitations/implications One limitation was that data were collected from two relatively small convenience samples. Practical implications Logo substitution can be of value when a company faces a situation when advertising is banned or restricted, when the target market is saturated with marketing stimuli (clutter) and when there is a risk that aggressive advertising can lead to psychological reactance. The purpose of logo substitution would then be to unobtrusively activate mental representations closely related to the original logo. Originality/value The central contribution of this study is that it demonstrates how the principles of implicit social cognition, implicit learning and logo substitution can be used by marketers to overcome the undesirable and even adverse advertising circumstances they sometimes face.

High Linear Energy Transfer

Theoretical and experimental studies of free-radical yields in oriented DNA samples exposed to ionizing radiation with high linear energy transfer at 77 K are discussed. The dependence of radical yields on the orientation of DNA chains relative to the particle flux is being investigated to gain insight into the role of intramolecular energy and charge transfer processes in radical production and decay. Model calculations based on a thermal-spike approximation are presented and their limitations for predicting the orientation dependence of radical yields observed after neutron irradiation (see C. M. Arroyo et al. Int. J. Radiat. Biol. 50, 789 (1986)) are discussed. A more mechanistic model based on the high mobility of excess electrons in hydrated DNA (D. van Lith et al. J. Chem. Soc. Faraday Trans. 1, 82, 2933 (1986)) is outlined.

Using MD simulation the conformation of the fibril forming protein amyloid beta at the air-water interface. It is found that adsorption at the air-water interface induces the formation of aggregation prone alpha-helical conformations, consistent with experimental studies of amyloid beta. Adsorption on the air-water interface also reduces the number of distinct conformations that the protein exhibits. This provides insight into the role of protein conformational change into the enhancement of protein fibrillation at interfaces.

This paper will explore possible ways of integrating humanities disciplines in medical education.In today's world, medical students have to learn to understand the social and cultural environment in which medicine is practiced. The humanities have long since have been the principal site of diversity in the academy. Now they can help medical students come to terms with diversity that is the context ot today's medicine.Studies in arts and humanities help recognize the limitations of purely biotechnical approach to patient care, in complex and paradigm-changing ways. Such studies also pave the way for understanding how social assumptions and values play out in healthcare policies. In sum, the humanities provide an additional insight into the human condition, allowing students “to consider human beings in their totality,” in the words of Jean Delay, a pioneer of psychopharmacology who also maintained a literary career throughout his life.Furthermore, humanities contribute to the development of complex interpretive skills, embracing affective aspects of intelligence as much as they embrace conventional rationalist forms of inquiry such as logic, analysis, deconstruction and critique. There is some evidence that medical students who have an additional background in the humanities are less vulnerable to burnout while studying and go on to perform better in important areas of practice. Approaches to developing specific learning outcomes and curricular guidelines will be discussed.
