Abstract:
Abstract In recent years, theories of rhythm have been proposed by a number of different disciplines, including historical poetics, generative metrics, cognitive literary studies, and evolutionary aesthetics. The wide range of fields indicates the transdisciplinary nature of rhythm as a phenomenon, as well as its complexity, highlighting the degree to which many of the central questions surrounding rhythm remain extraordinarily difficult even to state in terms that can traverse the disciplinary boundaries effortlessly transgressed by rhythm as a phenomenon. In particular, any theory of rhythm, whether in music, dance, sociology, or language, must grapple with two quandaries. First, the precise site of rhythm remains opaque: rhythms occur in, affect, and are produced by all of bodies, cultures, and universals (whether metaphysical or species-physiological). What is the relation between species-wide characteristic, individual body, cultural context, and the history of art making in the experience of rhythm? Second, rhythm is simultaneously a phenomenon of fixed, organizing form and one of dynamic, changing flow. How can rhythm encompass both the measurement of regular recurrences across time and the organizing of temporal phenomena as they unfold? In this article, I draw on Emile Benveniste and Henri Meschonnic to elucidate these quandaries or conflicts before turning to Friedrich Nietzsche’s work on rhythm. I argue that Nietzsche’s work with rhythm provides a historically situated model for how we might continue to take the questions and conflicts within rhythm seriously, rather than privileging an abstract and universally applicable theory of rhythm. This model is especially crucial for our own historical moment, when cultural-political emphasis on science and technology at the expense of aesthetics devalues all insights not presented in the form of countable data points or empirically testable facts. Nietzsche is, of course, one of the great critics of positivist-scientistic epistemologies, part of a long tradition questioning the naturalness of natural-scientific paradigms and alerting us to the metaphors at play even in the ›hard sciences‹. I use rhythm as one paradigmatic place to resist the importation of scientistic thought into discussions of language, literature, and culture. I show how Nietzsche’s writings on rhythm prove illuminating for contemporary understandings of rhythm because the tensions in his work are shaped by the quandaries inherent to rhythm that I have used Benveniste and Meschonnic to elaborate, namely the question of rhythm’s site as individual, cultural, or universal, and the conflict between rhythm as form and as flow. The question of the site of rhythm appears in Nietzsche’s discussions of Greek and Latin meters both in his philological works, in his aphorisms, and in his letters: on the one hand, he argues that Greek and Latin metrical and rhythmic resources are irrevocably lost to modern cultures (indicating that rhythm is a product of culture), while on the other, he emphasizes the impact of rhythm on the body and offers advice for replicating Ancient metrical and rhythmic techniques (suggesting that rhythm is based on physiological universals). And the conflict between flow and form appears as Nietzsche praises both the productive constraint created by large-scale, architectonic, or macro-formal rhythms and the freedom from such constraint enabled by small-scale, leitmotiv-based, or micro-formal rhythms. The conflicts in Nietzsche’s work between the loss and recovery of Ancient rhythms and between rhythm as small scale freedom vs. large scale constraint thus represent one particular unfolding of the dilemmas for rhythmical theory worked out by Benveniste and Meschonnic. The various modern disciplines engaged with rhythm will answer different sets of these questions in different ways. Most practitioners of, e. g., evolutionary aesthetics, neuroaesthetics, or cognitive poetics would no doubt contend that they are using the tools of the natural sciences to investigate long-standing humanistic inquiries. Nietzsche, as a critic of his own era’s scientific positivism who allows tensions inherent in these questions to remain open in his own work, is an ideal interlocutor with whom to ask whether even the adoption of these tools ends up placing excessive faith in natural-scientific paradigms and undercutting other—affective, bodily, metaphorical, poetic, etc.—ways of knowing, as I demonstrate briefly in the examples of evolutionary aesthetics and generative metrics. Because Nietzsche leaves open the conflicts over rhythm’s site and its qualities as form or flow, he can use individual bodily experience to make physiological arguments about the effects of rhythm on culture and vice versa: Nietzsche takes his bodily response to be an index of cultural values inherent to rhythmical practices. The particular values that Nietzsche critiques shift across his career—early on he condemns German musical and poetic rhythms for being too rigid, while later he sees them as pathologically heightening affect and emotion. In both cases, detrimental rhythmic practices lead to detrimental bodily practices and to the degeneration of culture, while rhythmic practices work as a bodily and cultural corrective. In his critiques of German forms and praises of Greek forms, and in the moments in which he brings them together, Nietzsche thus asserts the complex interrelation of culture, body, and history.

Abstract:
Drawing on observations of the performances of street preachers in the United States—as well as the texts that inform them—this article explores the concept of rhythm within and beyond the anthropology of religion. More specifically, it develops an expansive concept of rhythm as multiple and interactive, focusing not on a singular rhythm, but on the rhythmic translations that shape the practice of street preaching. First, I argue that the material rhythms of urban infrastructure constrain the narrative rhythms of the street preacher’s sermon, producing a distinct homiletics. I then suggest that the ideological rhythms of war animate the narrative rhythms of the street preacher’s sermon, linking military strategies with tactics of evangelism. Examining the material, narrative, and ideological rhythms of streets, sermons, and military doctrine, this article advances an analytic framework whereby the intersecting rhythmic tensions that shape performance can be registered.

Abstract:
This article is written by a composer on his own music. It describes a set of rhythmic organization principles used in my compositional research since 1989. These principles greately expand what is traditionally known as "modal rhythm" , which appears for the first time in the music of the 12th century polyphonists of the Notre Dame School: Leoninus and Perotinus. For this reason, I call this group of rhythmic principles "expanded modal rhythm" . They are a part of a larger context of temporal organization principles designed to generating ametric textures, complex polyrhythm and cross rhythms, and certain desired types or rhythmic flow. I use examples taken from four of my compositions.

Abstract:
Frequency-domain analysis was used to characterize the relationships among the rhythmic discharges recorded simultaneously from two to four sympathetic nerves in unanesthetized decerebrate cats. The major new findings were as follows. 1) The 10-Hz rhythmic discharges of different nerves cohered strongly in baroreceptor-innervated and -denervated cats. 2) The interval between the discharges of two nerves was frequency dependent in the 10-Hz band in some cats, supporting the view that the 10-Hz rhythm is generated by multiple central circuits that are coupled. 3) In some cases the central circuits responsible for the 10-Hz rhythms nonuniformly affected different nerves. 4) In baroreceptor-innervated cats the coherence values for the cardiac-related discharges of any two nerves were significantly higher than those for the 10-Hz rhythms. 5) In baroreceptor-denervated cats the 10-Hz rhythmic discharges of different nerves cohered more strongly than the 2- to 6-Hz rhythms. 6) The 10-Hz rhythm usually was not a harmonic of the 2- to 6-Hz or cardiac-related rhythm. Thus these rhythms are generated independently.

Abstract:
We demonstrate distinct α- (7–14 Hz) and β-band (15–30 Hz) rhythms in rat somatosensory cortex in vivo using epidural electrocorticography recordings. Moreover, we show in rats that a genuine β-rhythm coexists alongside β-activity that reflects the second harmonic of the arch-shaped somatosensory α-rhythm. This demonstration of a genuine somatosensory β-rhythm depends on a novel quantification of neuronal oscillations that is based on their rhythmic nature: lagged coherence. Using lagged coherence, we provide two lines of evidence that this somatosensory β-rhythm is distinct from the second harmonic of the arch-shaped α-rhythm. The first is based on the rhythms' spatial properties: the α- and β-rhythms are demonstrated to have significantly different topographies. The second is based on the rhythms' temporal properties: the lagged phase-phase coupling between the α- and β-rhythms is demonstrated to be significantly less than would be expected if both reflected a single underlying nonsinusoidal rhythm. Finally, we demonstrate that 1) the lagged coherence spectrum is consistent between signals from rat and human somatosensory cortex; and 2) a tactile stimulus has the same effect on the somatosensory α- and β-rhythms in both rats and humans, namely suppressing them. Thus we not only provide evidence for the existence of genuine α- and β-rhythms in rat somatosensory cortex, but also for their homology to the primate sensorimotor α- and β-rhythms.

Abstract:
We addressed how rhythm complexity influences auditory–motor synchronization in musically trained individuals who perceived and produced complex rhythms while EEG was recorded. Participants first listened to two-part auditory sequences (Listen condition). Each part featured a single pitch presented at a fixed rate; the integer ratio formed between the two rates varied in rhythmic complexity from low (1:1) to moderate (1:2) to high (3:2). One of the two parts occurred at a constant rate across conditions. Then, participants heard the same rhythms as they synchronized their tapping at a fixed rate (Synchronize condition). Finally, they tapped at the same fixed rate (Motor condition). Auditory feedback from their taps was present in all conditions. Behavioral effects of rhythmic complexity were evidenced in all tasks; detection of missing beats (Listen) worsened in the most complex (3:2) rhythm condition, and tap durations (Synchronize) were most variable and least synchronous with stimulus onsets in the 3:2 condition. EEG power spectral density was lowest at the fixed rate during the 3:2 rhythm and greatest during the 1:1 rhythm (Listen and Synchronize). ERP amplitudes corresponding to an N1 time window were smallest for the 3:2 rhythm and greatest for the 1:1 rhythm (Listen). Finally, synchronization accuracy (Synchronize) decreased as amplitudes in the N1 time window became more positive during the high rhythmic complexity condition (3:2). Thus, measures of neural entrainment corresponded to synchronization accuracy, and rhythmic complexity modulated the behavioral and neural measures similarly.

Abstract:
Abstract International Relations (IR) has rarely considered rhythm as a topic of analytical attention. Yet rhythms permeate many social and political phenomena, and their study contributes to core debates and empirical insights in contemporary IR. Rhythms are similar to but distinct from other forms of repetitive, iterative social action that have garnered increasing interest in IR, such as practices, habits, and routines. Each of these phenomena has rhythmic elements, but not all rhythmic phenomena are practical, habitual, or routine. Rhythm, then, is a distinct category of iterative action that is effectively positioned to unpack a wider array of practices in a broader range of cases. Moreover, contrary to common conceptions as simple repetition, the multiplicity and dynamism of social rhythms hold the potential to produce novel political formations. This article outlines a framework for the study of rhythms in IR by delineating some key features of social rhythms and three kinds of sociopolitical effects that they have in collective contexts. These theoretical developments are empirically applied to understand neglected aspects of mass mobilization during the Arab uprisings of 2011.

Abstract:
‘Parlando-rubato’ rhythm in Bartók’s thinking, does not mean complete rhythmic freedom; it is not necessarily accompanied by rubato tempi or rubato modes of interpretation. Musical declamation approximating to the rhythm of speech can be regulated by strict metrical structures, even if these do not follow a regular beat. Bartók’s writings dealing with the parlando phenomenon support the complexity and variability of ‘parlando-rubato’ as folk rhythms and performing practices. It was precisely the manifold nature of the parlando-rubato rhythm that enabled it to become the most important rhythmic foundation for musical declamation in Bluebeard’s Castle . The different level of rhythmic freedom of the characters not only reveal the contrast between their characteristic parlando types but also communicate their own personal rhythmic profile. The main aim of this study is to highlight those aspects of this musical phenomenon which greatly contributed to the 20th-century renewal and emancipation of rhythm while not eliminating rhythmic patterns based on bars.

Abstract:
This review paper discusses rhythmic interactions and distinguishes them from non-rhythmic interactions. We report on communicative behaviours in social and sexual contexts, as found in dyads of humans, non-human primates, non-primate mammals, birds, anurans and insects. We discuss observed instances of rhythm in dyadic interactions, identify knowledge gaps and propose suggestions for future research. We find that most studies on rhythmicity in interactive signals mainly focus on one modality (acoustic or visual) and we suggest more work should be performed on multimodal signals. Although the social functions of interactive rhythms have been fairly well described, developmental research on rhythms used to regulate social interactions is still lacking. Future work should also focus on identifying the exact timing mechanisms involved. Rhythmic signalling behaviours are widespread and critical in regulating social interactions across taxa, but many questions remain unexplored. A multidisciplinary, comparative cross-species approach may help provide answers. This article is part of the theme issue ‘Synchrony and rhythm interaction: from the brain to behavioural ecology’.

Abstract:
Two experiments explore hypotheses about rhythm and contour in recognition of simple pitch strings (melodies). Target melodies that differed with respect to pitch relationships (interval and contour pitch differences) and rhythm, were presented to ordinary listeners who were told to learn the melodies (Phase I). In a subsequent recognition test (Phase II), listeners had to recognize these same target melodies although they were transposed to a different musical key. In recognition, target melodies appeared in the original rhythm or in new rhythms that simulated some pause properties of the original rhythm. Target melodies were interspersed with decoy melodies that either preserved the pitch contour of targets or did not; all appeared in the original rhythm and in new rhythms. Results indicated that a new rhythmic context lowered recognizability of target melodies, and that decoys were most confusing when they possessed the same “dynamic shape” (contour-plus-rhythm) as targets (Experiment 1). Also, target recognition improved with Phase I familiarity (Experiment 2), although rhythmic shifts remained detrimental across levels of target familiarity. Confusions based on “dynamic shape” accounted for a relatively high proportion of errors where familiarity with targets is low. Findings were interpreted in terms of a theory of context-sensitive dynamic attending in which remembering is assumed to involve recapitulation of the original rhythmical activities involved in attending to melodies.

Abstract:
Morse code is a unique exemplar of the inherent complexities of rhythm. Learning Morse code in wartime presented challenges to expedite skill acquisition. This thesis explored the strategies used to teach and learn Morse code in the second World War and investigated the resourceful techniques used by the WRANS in an empirical study. The first study investigated the teaching and learning strategies of wartime telegraphists to learn Morse code. Five WRANS described a series of techniques to learn Morse code, including rote learning and repetition, visualisation and pattern recognition, intoning and mnemonics, and music. Music provided effective training for the fundamental teaching and learning of Morse code by matching the rhythmical properties of Morse code to music. Music equipped Morse code operators with a unique approach to Morse code instruction. Learning Morse code with music was described as a way of making sense of the ‘rhythm’ and ‘shape’ of the Morse code letters and proved an invaluable aid to learning and teaching Morse code. The second study examined the effectiveness of learning Morse code with the aid of music. Novices formed two groups, Control Group (no music aid) and Music Group (with music aid). Results confirmed the effectiveness of music training in three Morse code letters, Q V, and A in two experiments, the first with known Morse code letters (Q V A) and the second with unknown letters. The Music Group accurately identified 90% of known and unknown Morse code letters compared to the Control Group who identified less then 50% of known and unknown Morse code letters. This thesis explored the transferable attributes of rhythm perception in music as a teaching and learning mechanism for Morse code. There is extensive research on the complex learning and retention of Morse code but the studies in this thesis have indicated that the ground-breaking wartime strategy of music and Morse code is a powerful duo. The investigation of learning and teaching strategies of the WRANS showed that musical rhythm influenced the skill acquisition of Morse code and the perceptual test suggests that current work in rhythm perception extends beyond music pedagogy and has further implications for all cognitive function.

Abstract:
Write Rhythm is a tech start-up launched in May 2016 in Denpasar, Indonesia. The mission of the company is to disrupt the music industry by offering a service that matches music producers with record labels worldwide (Ardie, 2017). The start-up focuses on electronic music and aims to service the industry equally at both ends. In brief, Write Rhythm sends the tracks uploaded by producers to labels that are looking for new talents, streamlining and improving the process of demo submission, that is otherwise long, tedious and often ineffective. Since the service offers an advanced filtering system, artists can send their demos to the labels that fit their sound best and, on the other side, labels can receive only the music that is consistent with their particular brand (Write Rhythm 2017). Currently, Write Rhythm lists more than 350 independent record labels across 80 electronic music sub-genres and is working to gather a larger number of users as well as to extend its genres list. Moreover, the company is entering a crucial time of transition, characterized by major changes such as the launch of the version 2.0 of the platform and a new funding round (Write Rhythm 2017). In May 2017, I have worked at Write Rhythm as a Marketing Intern. During this placement, my tasks focused on three areas of business: 1. Competition: by analyzing the competitors’ products and the influence of artists and labels on the company’s operations. 2. Customer Acquisition: by formulating new customer acquisition strategies, mostly through mail campaigns. 3. Social Media: by developing the concept of a new sub-brand and creating content for it. In this context, the main limitation has been time. In fact, although being intense, this experience has been concentrated in only one month. Therefore, I did not have enough time to work on every aspect of the business. However, especially thanks to a continuous and insightful dialogue with Jody Taylor, the company’s founder and CEO, I have had the opportunity to have an overview of what operations are carried out at Write Rhythm and how they are conducted. For these reasons, in this report, I aim to link this experience with my academic studies by applying some of the marketing theories, models and frameworks I have learned during my master’s. In particular, my analysis takes the stock of the current situation of the company from the standpoint of the competition, the market and the online marketing mix, with the objective of suggesting relevant recommendations. Consequently, this report takes the form of a marketing report and features the following areas of analysis: 1. Competitive Analysis: by applying Porter’s Five Forces framework, the micro environment as well as the direct competitors’ offers are examined. 2. Market Analysis: by applying the segmenting, targeting and positioning model, the customers’ characteristics and the targeting strategies as well as the positioning of the brand and the product in the mind of consumers are described. 3. Online Marketing Mix Analysis: by applying an online marketing mix analysis, the strategies developed through the website, social media and sub-brands are analyzed. This report also provides relevant recommendations that could assist the company in facing its future challenges: 1. As a result of the Competitive and Market analyses, the development of a partnership with a company with which there is a high degree of product complementarity is suggested. 2. In the light of the Competitive and Market analyses as well as of the previous recommendation, the introduction of a new pricing strategy is suggested. 3. On the basis of the Market and Online Marketing Mix analyses, an extension of the sub-brand line in growing segments of the electronic music industry is suggested.

Abstract:
Hippocampal theta rhythm is an oscillatory activity in the range of 3 – 12 Hz, prominently observed in hippocampal extracellular field recordings in vivo. Hippocampal theta rhythm has been closely associated with episodic memory and spatial learning in both humans and animals. Here, I describe two research projects I carried out in the course of my Ph.D., exploring several different types of neurons that could serve as potential rhythm generators for hippocampal theta rhythm. The medial septum and diagonal band of Broca (MS-DBB) has long been known to provide crucial inputs for the generation of hippocampal theta rhythm in vivo. The 'septohippocampal network' thus refers to the hippocampal formation, the MS-DBB and the connections between the two structures. While there has been many studies investigating the contributions of cholinergic and GABAergic MS-DBB neurons, the role of the recently described glutamatergic MS-DBB neurons in the septohippocampal network and theta rhythm generation remains unknown. In order to address this issue, for my first project, I investigated the electrophysiological properties of the glutamatergic MS-DBB neurons and examined their functional role in the septohippocampal network. Recently, a study using a complete hippocampal preparation in vitro demonstrated that the CA1 region of the hippocampal formation can generate its own theta oscillations independently of external inputs. It is unknown which CA1 interneuron subtype plays a key role in generating this intrinsic CA1 theta rhythm. During in vivo theta rhythm, parvalbumin (PV)- and somatostatin (SOM)-expressing interneurons fire strongly phase-locked to field theta rhythm, indicating that they may be good candidates for potential theta rhythm generators. Thus, for my second project, I explored the intrinsic properties of PV and SOM interneurons and examined their cellular behaviour during in vitro CA1 theta rhythm. Furthermore, I investigated the causal role of these interneurons in CA1 field theta oscillations using optogenetic silencing methods. Results from the first project illustrate that in addition to the well-known cholinergic and GABAergic septohippocampal pathway, the glutamatergic MS-DBB neurons provide a functional excitatory synaptic input to hippocampal neurons that may contribute to theta rhythm generation and synchronization across the septohippocampal network. Results from the second project demonstrate that both synaptic and intrinsic factors determine the interneurons' firing patterns during theta rhythm and that PV interneurons, with their highly synchronous and powerful inhibitory outputs onto pyramidal cells, appear to play an important role in generating the field theta signal. These findings provide new information about the potential role of several different neuronal classes in the septohippocampal network in relation to theta rhythm generation. It is my hope that a greater understanding of this matter will bring new insights into the mechanisms with which neural oscillations contribute to essential operations of the brain such as learning and memory.
Le rythme thêta de l'hippocampe est une activité neuronale oscillatoire dans la gamme de 3 - 12 hertz, pouvant être primordialement observée durant les enregistrements extracellulaires de champ hippocampal in vivo. Le rythme thêta hippocampal a été étroitement associé à la mémoire épisodique et à l'exploration spatiale chez les humains et les animaux. Dans cette thèse, je décris deux projets de recherche mis à exécution au cours de mon Ph.D. et explorant différents types de neurones qui pourraient potentiellement servir de générateurs pour les rythmes thêta de l'hippocampe. Le septum médian et la bande diagonale de Broca (MS-DBB) ont été longtemps reconnus comme les zones principales fournissant les entrées cruciales pour la génération du rythme thêta de l'hippocampe in vivo. Le « réseau septohippocampal » se rapporte ainsi à la formation hippocampale, au MS-DBB et aux raccordements entre les deux structures. Bien qu'un grand nombre d'études ait déjà exploré la contribution des neurones cholinergiques et GABAergic du MS-DBB dans le réseau septohippocampal et dans la génération des rythmes thêta, le rôle d'une population de neurones glutamatergiques nouvellement découverte au niveau du MS-DBB, reste pour l'instant inconnu. Afin d'aborder cette question, pour mon premier projet, j'ai étudié les propriétés électrophysiologiques des neurones glutamatergiques du MS-DBB et j'ai examiné leur rôle fonctionnel dans le réseau septohippocampal. Récemment, une étude utilisant une préparation hippocampale complète in vitro a par ailleurs démontré que la région CA1 de la formation hippocampale peut produire ses propres oscillations thêta, indépendamment des entrées externes. L'identité des sous-types d'interneurones qui sont impliquées dans la production de ce rythme thêta intrinsèque à CA1 est pour l'instant inconnue. Pendant le rythme thêta in vivo, les interneurones qui expriment la parvalbumin (PV) - ou la somatostatin (SOM) - déchargent fortement et à phase-verrouillé sur le rythme extracellulaire, indiquant qu'elles pourraient être de bons candidats de générateurs pour le rythme thêta. Ainsi, pour mon deuxième projet, j'ai exploré les propriétés intrinsèques des interneurones PV et SOM et j'ai examiné leur comportement cellulaire au cours du rythme thêta enregistré in vitro dans la région CA1. En outre, j'ai examiné le rôle causal de ces interneurones dans la thêta de champ en utilisant des méthodes optogénétiques pour contrôler l'activité neuronale. Les résultats du premier projet illustrent qu'en plus des voies septohippocampales cholinergiques et GABAergiques bien connues, les neurones glutamatergiques du MS-DBB fournissent une entrée synaptique excitatrice fonctionnelle aux neurones de l'hippocampe. Ces neurones pourraient ainsi contribuer à la génération et à la synchronisation des rythmes thêta à travers le réseau septohippocampal. Les résultats du deuxième projet démontrent; 1) que plusieurs facteurs synaptiques et intrinsèques déterminent les modes de mise à feu des interneurones pendant le rythme thêta et ; 2) que les interneurones PV, avec leurs sorties inhibitrices fortement synchrones et puissantes sur les cellules pyramidales, semblent jouer un rôle prépondérant dans le contrôle du signal thêta de champ. Ces résultats fournissent de nouvelles informations au sujet du rôle potentiel de différentes classes neuronales du réseau septohippocampal par rapport à la génération du rythme thêta. J'ai grand espoir que ces travaux mèneront à une meilleure compréhension des mécanismes avec lesquels les oscillations neurales contribuent aux opérations essentielles du cerveau telles que l'apprentissage et la mémoire.

Abstract:
In recent years, short-form videos have gained popularity and the editing of these videos, particularly when motion is synchronized with music, is highly favored due to its beat-matching effect. However, detecting motion rhythm poses a significant challenge as it is influenced by multiple factors that make it difficult to define using explicit rules. While traditional methods attempt to define motion rhythm, they often yield unsatisfactory results. On the other hand, learning-based methods can extract motion rhythm without relying on explicit rules but require high-quality datasets. Unfortunately, existing datasets simply substitute music rhythm for motion rhythm which are not equivalent. To address these challenges, we present the motion rhythm dataset AIST-M2B, which is annotated with meticulously curated motion rhythm labels derived from the profound correlation between motion and music in professional dance. We propose a novel network architecture called M2BNet that is specifically trained on AIST-M2B to effectively extract intricate motion rhythms by incorporating both human body structure and temporal information. Additionally, we introduce a pioneering algorithm for enhancing motion rhythm synchronization with beats. Experimental results substan- tiate the superior performance of our method compared to other existing algorithms in the domain of motion rhythm analysis.

Abstract:
"Dyslexia is one of the most frequent specific learning disorders which has often been associated with deficits in phonological awareness mainly caused by auditory and visual inabilities to recognize and discriminate phonemes and graphemes within words. Neuroimaging techniques like EEG recordings have been widely used to assess hemispheric differences in brain activation between students with dyslexia and their typical counterparts. Although dyslexia is a lifelong disorder which persists into adulthood, very few studies have been carried out targeting in adult population. In this study, we examined the brain activation differences between 14 typical (control group) and 12 university students with dyslexia (experimental group). The participants underwent two tasks consisting of 50 3-word groups characterized by different degrees of auditory and visual distinctiveness. The whole procedure was recorded with a 14-sensor sophisticated wearable EEG recording device (Emotiv EPOC+). The findings from the auditory task revealed statistically significant differences among the two sets of groups in the left temporal lobe in ?, ? and ? rhythms, in the left occipital lobe in ? rhythm, and in the right prefrontal area in ?, ? and ? rhythms, respectively. The students with dyslexia reported higher mean scores only in ? rhythm in the left temporal lobe, and in ?, ? and ? rhythms in the right prefrontal area. Concerning the visual task, statistically significant differences were evident in the left temporal lobe in ?, ? rhythms, in the occipital lobe in ?, ? and ? rhythms, in the parietal lobe in ? rhythm, and in the right occipital lobe in ?, ? and ? rhythms. The students with dyslexia reported higher mean scores only in the ? rhythm of both the left and right occipital lobe. The results indicate that there are differences in the hemispheric brain activation of students with or without dyslexia in various rhythms in both experimental conditions, thus, shedding light in the neurophysiological discrepancies between the two groups. It also lays great emphasis on the necessity of carrying out more studies in adult population with dyslexia."

Abstract:
Circadian rhythms are internal manifestations of the solar day that allow adaptations to environmental-temporal changes. Mood disorders are often associated with disrupted circadian clock-controlled responses, whereas circadian rhythm disruption is correlated to jet lag, night-shift work, or to exposure to artificial light at night. Modern lifestyle patterns lead to circadian rhythm disruption, and it results in several diseases. Circadian rhythm disruption is one of the factors most often investigated, besides smoking, diet, fatigue and quality sleep, increased body mass index and obesity. Lack of enough daylight at daytime and the exposure to electric light at nighttime can disconnect people from the natural environment and lead to psychological issues. The aims of the current research are to analyze the circadian potential of three building models based on WELL Certification, to compare their performance, and to draw design guidelines about circadian rhythm and users’ well-being to be applied to office buildings in São Paulo City, São Paulo State, Brazil. Adaptive Lighting for Alertness (ALFA tool) was used to calculate the Equivalent Melanopic Lux for WELL Certification criteria in the investigated scenarios. Results have indicated that shallow office plans can benefit users by providing them with regular circadian rhythm o help improving their sleep quality, reducing their stress and preventing severe diseases.

Abstract:
Chilling-sensitivity is an important agricultural problem in both the U.S. and Israel. Most research attention has focused so far on herbaceous crop plants, even though the problem is also acute in the fruit tree industry. Under BARD funding we made substantial progress in identifying the mechanisms involved in the disruption of photosynthesis following a chill in mango. Our investigation with fruit trees has been substantially accelerated by drawing on our knowledge and experience with herbaceous crops. The four original research objectives, focused or discovering the underlying mechanisms of chill-induced inhibition of photosynthesis in fruit trees, and the main achievements are listed below. [1] Separating stomatal from non-stomatal components of chilling on photosynthesis in fruit trees. We found evidence that the dark chill-induced inhibition of photosynthesis in mango was E combination of both stomatal and mesophyll components. [2] Differentiating photo damage from light-induced photo protection of photosystem II (PSII). Dark chilling exacerbate high light photoinhibition, as a result of primary inhibition in the carbor reduction cycle. Nevertheless, in Israeli orchards we observed chronic photoinhibition of PSII photochemistry in the winter. This photo damage was reversible over a few days if sunlight was attenuated with filters or night temperature rose. Practical implications of this finding deserve further investment. Additional achievement was the development of a new biophysical tool to study macro-structural changes of LHCII particles in intact, attached leaves. [3] Determine the role of oxidative stress in the dark-chilling-induced inhibition, with emphasis on oxygen radical scavenging, lipid peroxidation and redox-controlled carbon-cycle enzymes. We found an increase in lipid peroxidation following a dark chill, and partial protective effects or an antioxidant. However, the photoinhibition observed in mango orchards in Israel during the winter did not appear to be a general oxidative stress. [4] Investigate whether chilling interferes with the diurnal and circadian rhythm of gene expression of key photosynthetic proteins as has been shown for chilling-sensitive crop plants. The results indicated that most of the circadian rhythm in photosynthesis was due to reduced lea: internal CO2 concentrations during the subjective night, as a result of rhythmic stomatal closure Chilling-induced interference with circadian timing in mango, does not play the central role in chilling inhibition of photosynthesis that has previously been demonstrated in certain chilling sensitive herbaceous plants. Practical implications of the research achievements are feasible, but require few more years of research.
