The Luminosity Distribution of Local Group Galaxies

From a rediscussion of Local Group membership, and of distances to individual galaxies, we obtain $M_V$ values for 35 probable and possible Local Group members. The luminosity function of these objects is well fitted by a Schechter function with faint end slope $\alpha = -1.1 \pm 0.1$. The probability that the luminosity distribution of the Local Group is a single Schechter function with $\alpha$ steeper than -1.3 is less than 1 per cent. However, more complicated luminosity functions, such as multi-component Schechter functions with steep faint-end slopes, cannot be ruled out. There is some evidence that the luminosity distribution of dwarf spheroidal galaxies in the Local Group is steeper than that of dwarf irregular galaxies.Comment: 13 pages, 2 figures, accepted for publication in The Astronomical Journal.

A review of the (potential) implications of climate change for policing practice worldwide

Climate change is now considered more than just an environmental issue, with far-reaching effects for society at large. While the exact implications of climate change for policing practice are still unknown, over the past two decades criminologists have anticipated that climate change will have a number of effects that will result in compromised safety and security. This article is informed by the outcome of a co-creation workshop with 16 practitioners and scholars of diverse backgrounds based in The Netherlands, who sought to conceptualize and systematize the existing knowledge on how climate change will most likely impact the professional practice of the Dutch (or any other) police. These challenges, with varying degrees of intensity, are observable at three main levels: the societal, organizational, and individual level. These levels cannot be separated neatly in practice but we use them as a structuring device, and to illustrate how dynamics on one level impact the others. This article aims to establish the precepts necessary to consider when exploring the intersection between climate change and policing. We conclude that much still needs to be done to ensure that the implications of climate change and the subject of policing are better aligned, and that climate change is recognized as an immediate challenge experienced on the ground and not treated as a distant, intangible phenomenon with possible future impacts. This starts with creating awareness about the possible ways in which it is already impacting the functioning of policing organizations, as well as their longer-term repercussions.</p

Separating acoustic deviance from novelty during the first year of life:A review of event-related potential evidence

Orienting to salient events in the environment is a first step in the development of attention in young infants. Electrophysiological studies have indicated that in newborns and young infants, sounds with widely distributed spectral energy, such as noise and various environmental sounds, as well as sounds widely deviating from their context elicit an event-related potential (ERP) similar to the adult P3a response. We discuss how the maturation of event-related potentials parallels the process of the development of passive auditory attention during the first year of life. Behavioral studies have indicated that the neonatal orientation to high-energy stimuli gradually changes to attending to genuine novelty and other significant events by approximately 9 months of age. In accordance with these changes, in newborns, the ERP response to large acoustic deviance is dramatically larger than that to small and moderate deviations. This ERP difference, however, rapidly decreases within first months of life and the differentiation of the ERP response to genuine novelty from that to spectrally rich but repeatedly presented sounds commences during the same period. The relative decrease of the response amplitudes elicited by high-energy stimuli may reflect development of an inhibitory brain network suppressing the processing of uninformative stimuli. Based on data obtained from healthy full-term and pre-term infants as well as from infants at risk for various developmental problems, we suggest that the electrophysiological indices of the processing of acoustic and contextual deviance may be indicative of the functioning of auditory attention, a crucial prerequisite of learning and language development
