Do So

A decade ago DeVogler and Ebersole reported that young adolescents were able to express the fact that they had personal meaning in their lives. In the present study we found that even younger children (26 first graders) could do so also when personal meaning was defined to them as that which in their whole life is most important to them. The high frequency of those reporting a personal meaning goes against the position that a large percentage of individuals in our modern society lack personal meaning.

Objective: To evaluate the frequency of perceived ethical misconduct in the practice of neuropsychology in Mexico. Method: One hundred fourteen psychologists answered a survey which assessed perceptions of ethical misconduct in four areas of professional practice in the field of neuropsychology.Results: The area of professional training contained the highest percentage of perception of ethical misconduct, followed by research and publications, clinical care, and professional relationships. Conclusion: The high frequency of ethical misconduct perceived by neuropsychology professionals in Mexico is a cause for concern. The results suggest the need to create and implement a system to make sure that professionals follow the ethics standards required by the profession, and to provide consequences for those who fail to do so. The profession of neuropsychology and training of professionals in the field must be regularized in the country, to reduce the frequency of future ethical misconducts.

Rodents in their natural environment use their whiskers to distinguish between surfaces having subtly different textures and shapes. They do so by actively sweeping their whiskers across surfaces in a rhythmic motion. To determine how textures are transformed into vibration signals in whiskers and how these vibrations are expressed in neuronal discharges, we induced active whisking in anesthetized rats, monitored the movement of whiskers across surfaces, and concurrently recorded from trigeminal ganglion (TG) neurons. We show that tactile information is transmitted through high-frequency micromotions superimposed on whisking macro motions. Consistent with this, we find that in most TG neurons, spike activity, and high-frequency micromotions are closely correlated. To determine whether these vibration signals can support texture discrimination, we examined their dependence on surface roughness and found that both vibration signals carry information about surface coarseness. Despite a large variability in this translation process, different textures are translated into distinct vibrations profiles. These profiles depend on whiskers properties, on radial distance to the surface, and on whisking frequency. Using the characteristics of these signals, we employ linear discriminant analysis and found that all whiskers were able to discriminate between different textures. While deteriorating with radial distance, this classification did not depend on whisking frequency. Finally, increasing the number of whisks and integrating tactile information from multiple whiskers improved texture discrimination. These results indicate that surface roughness is translated into distinct whisker vibration signals that result in neuronal discharges. However, due to the dynamic nature of this translation process, we propose that texture discrimination may require the integration of signals from multiple spatial and temporal sensory channels to disambiguate surface roughness.

This chapter analyses the MiFID II rules on algorithmic trading (AT), including high-frequency trading (HFT). The author argues that AT raises serious issues of volatility and systemic risk, and HFT issues of systematic front-running of investors. However, opinions are divided on the benefits and risks of these techniques, especially HFT. MiFID II takes a technical approach mostly focused on prevention of a repeat of the 2010 ‘Flash Crash’ with provisions on market abuse. The ESMA 2012 Guidelines remain the most effective regulation to frame the development of HFT, able to tackle market developments with relative speed. However, with implementation of the directive still far away, prosecution of market abuse among HFT traders by legislators and supervisors could lead to a de facto ban of HFT in some Member States. However, the author argues that supervisors would need to allocate scarce resources to it, at great cost, and only the most motivated supervisors will do so.

Attitude Toward Death

The goal of the presented research was to investigate if wisdom plays a mediating role in the relationships between meaning in life and the attitude toward death in the period of middle and late adulthood. A study was carried out that included 567 persons aged 40 to 75 years. Three measures were used: Personal Meaning Profile, Three-Dimensional Wisdom Scale, and Death Attitude Profile-Revised. The conducted analyses allowed the authors to confirm the mediating role of wisdom in the relationships between meaning in life and fear of death as well as death avoidance in persons during the period of middle and late adulthood.

Cultural Hybrid

Africa is mired in problems and has been so for a very long time. In their attempts to rescue the situation, our forefathers took upon themselves the task of decolonization. Although this process began in earnest in the early 1960s, it has since stalled. Today there are few Africans, either in the secular realm or in religious orders, who dare to speak about decolonization. It is as if the continent is in a coma, its attendants paralyzed. We all seem to have reached the conclusion that the current worldview, provided by the neo-conservatives in Washington and London, is an unassailable universal, a definitive and final creed. This paper is an attempt to break the deadlock of the world’s current commitment to a monoculture. Focusing on the religious domain, in particular prayer, and using historical and critical methods, I argue that African Christians are alienated from their cultural beliefs, and as such their quest for meaning in life is eschewed. I maintain that the spirituality of individualism characterising Christianity is detrimental to Africa and as such it has to be replaced by the ‘spirituality of community’, which is grounded in African traditions and cultures. I conclude by suggesting that if African people want to find meaning in their life and existence here on earth, then they must do so by looking very carefully into their own cultures and traditions, and not disappear into alien cultures, or into some mono-cultural hybrid we witness today.

AbstractMany studies have documented that daily realized volatility estimates based on intraday returns provide volatility forecasts that are superior to forecasts constructed from daily returns only. We investigate whether these forecasting improvements translate into economic value added. To do so, we develop a new class of affine discrete-time option valuation models that use daily returns as well as realized volatility. We derive convenient closed-form option valuation formulas, and we assess the option valuation properties using Standard & Poor’s (S&P) 500 return and option data. We find that realized volatility reduces the pricing errors of the benchmark model significantly across moneyness, maturity, and volatility levels.
