This article discusses the identification of the wajhs regarded as weak in Kâsım b. Fîrruh esh-Shâtıbî’s poetical book Ḥırzu’l-emânî wa wajhu’t-tehânî that he wrote to make the differences of seven recitations (kırâ’ât-i sebaʻ) easy to memorize and the status of the practice of these wajhs in the Recitation Education. It is understood that Shatibi weakened these wajhs, sometimes explicitly with expressions such as leyse müʻavvelâ (لَيْسَ مُعَوَّلاَ) and lem yeṣıḥḥa fe yuḥmelâ (لَمْ يَصِحَّ فَيُحْمَلاَ), and sometimes indirectly with words such (...) as yüftelâ (يُفْتَلاَ)”, helhelâ (هَلْهَلاَ), uḫmilâ (اُخْمِلَا)” and mâce (مَاجَ)”. It is seen that there are eight of these wajhs in total; two of them are about method and six of them are about farshi differences. First of all, in the article the relevant wajhs are divided into two as the differences in the method and fersh. Afterwards it is narrated how these wajhs were handled in the significant sources of the qiraat field in addition to the interpretation style of the shârihs whom were accepted as authority in Ḥırzu’l-emânî. Finally, it is remarked that the wajhs of the tarîqs of Istanbul and Egypt which are in circulation in our country moreover the conditions of the practice of these wajhs in the qiraat education activities which are run in Arab world.

Abū Lahab (d. 2/624), one of the notables of Mecca, was one of the Prophet’s four uncles who reached the Islamic period. Abū Lahab who had generally good relations with the Prophet before the Islamic period developed bad attitudes towards his nephew when his prophethood was proclaimed and maintained these until his death. He, known for loyalty to his ancestor’s religion, did not believe in his nephew’s prophecy and was one of the chief antagonist and enemy of the Prophet in (...) Mecca. In addition to the fact that Abū Lahab had an identity devoted to his ancestor, by force of emphasis of social justice, the Prophet’s new religion defending equality among people and ordering to the faith of afterlife caused to have a strong opposition to his nephew. In the development of Abū Lahab’s opposing attitude his wife Umm Jamīl (d.?/?) plays a crucial role. In this article, Abū Lahab and the reasons which prompted to oppose to the Prophet and his religion were examined in detail. In addition, his life and relations with the Prophet before and after nubuwwa were detailed.Summary: bū Lahab is one of the four uncles of the Prophet Muḥammad, who reached the time of his prophethood. There is no information in the sources related to his birth, childhood and youth. His real name is known as ‘Abd al-‘Uzzā, and his nickname is Abū ‘Utba or, according to a weak opinion, Abū ‘Utayba. In most of the sources, it is noted that the (second) nickname of Abū Lahab was given by his father because he was so handsome, that he was shining like a fire or his cheeks were reddish as if they were fevering. Detailed information about Abū Lahab belongs to the post-prophetic period; information about his life before prophethood is less. Among these rare information there are findings that he was among the richest and most respected people of Mecca; saved by paying his diet a Meccan aristocrat who was held hostage by a caravan he met on the road to Mecca- al-Ṭāʾif; was involved with his friends in the theft incident against the golden gazelle statue in the Kaaba to supply his drinking money. The sources record that he was delighted with the birth of the Prophet and allowed his concubine to breastfeed the Prophet. Relations with the Prophet during this period, except for the anger of the Prophet because the supported Abū Ṭālib (d. 619) in a fight with Abū Ṭālib, generally followed a positive course. So much that he asked the two daughters of the Prophet to marry his two sons. However, these positive relations were broken and replaced by hostility after the Prophet was given the duty of prophethood and the Messenger of Allāh started to serve this duty.Abū Lahab, who can be regarded as a filiopietist, made every attempt to eliminate this new belief, which he saw as contrary to his ancestors' beliefs. He watched his nephew, did everything he could to deny what he was saying and prevent him from getting a response. He would grind him by throwing feces, carrion, animal droppings and stinking things to the door of his house to disturb him. He did not hesitate to increase the severity of this hostility. So much that he was among those who sentenced him to hunger by applying a socio-economic boycott to Muḥammad and his close relatives, Banū Hāshim and Banū Muṭṭalib, who supported him. However, in the pre-Islamic period, a sense of tribalism was dominant in Mecca and its nearby basin. This understanding was also dominant in the lower arms of the Quraysh tribe, who was a resident of Mecca. These communities, especially Banū Umayya and Banū Makhzūm, who represent the Mecca aristocracy, strongly opposed the prophecy of one of the Banū Hāshim. On the other hand, the Banū Hāshim adopted the Prophet with the same understanding. However, there was only one person who acted against this understanding among all Banū Hāshim, and this was Abū Lahab. He treated his nephew so much in hostility that he became the only person among the Mecca polytheists who was condemned by the Qur'ān. Perhaps the most important and influential factor in his persistence in a stubborn and systematic opposition to the Prophet, was his ancestral identity. In addition, in the pre-Islamic Mecca, the people were divided into social strata, inequality among people, and the aristocratic segment was the highest level of society. Islam advocated equality among people due to its vision of social justice. The Mecca aristocrats, including Abū Lahab, considered themselves superior to other people and thought that they were in no way equal to those who were lower in terms of property, position and nobility. This understanding was one of the most important factors that enabled Abū Lahab to take place in the block against this new belief system communicated by the Prophet. Again, one of the important factors in his displaying a stubborn and systematic opposition to the Prophet is that Islam accepts the belief in the hereafter as one of the basic principles of religion. Like the other polytheist Meccans, Abū Lahab did not believe in the resurrection. His wife Umm Jamīl was another factor of his opposition stance. The traditional rivalries between Umm Jamīl’s family Banū Umayya and Abū Lahab’s family Banū Hāshim, lead to a sense of competition against. This feeling prompted her to oppose the prophecy of one of the Banū Hāshim. So she always provoked her husband and Abū Lahab’s hatred toward his nephew never stopped to such an extent that it was mentioned in the surah Tabbat/al-Masad by a metaphor of carrying wood to feed the fire of hatred. Actually it was only Abū Lahab who was hostile to Muḥammad's prophethood among all the Banū Hāshim. With the prophethood of Muḥammad, beginning to display a stubborn and systematic opposition to Islam, Abū Lahab continued this opposition intensely in the following periods and died in the second year of the hijra with this attitude. His wife, Umm Jamīl, died with the same understanding and shared the same contractual fate with him. However, all her children -except for ‘Utayba (d.? /?) - were honored with Islam and were among the Prophet's distinguished companions. (shrink)

During gestation, fetomaternal exchange occurs in the villous tree (labyrinth) of the placenta. Development of this structure depends on tightly coordinated cellular processes of branching morphogenesis and differentiation of specialized trophoblast cells. The basal chorionic trophoblast (BCT) cell layer that localizes next to the chorioallantoic interface is of critical importance for labyrinth morphogenesis in rodents. Gcm1‐positive cell clusters within this layer initiate branching morphogenesis thereby guiding allantoic fetal blood vessels towards maternal blood sinuses. Later these cells differentiate and contribute to (...) the syncytiotrophoblast of the fetomaternal barrier. Additional cells within the BCT layer sustain continued morphogenesis, possibly through a repopulating progenitor population. Several mouse mutants highlight the importance of a structurally intact BCT epithelium, and a growing number of studies addresses its patterning and epithelial architecture. Here, we review and discuss emerging concepts in labyrinth development focussing on the biology of the BCT cell layer. (shrink)

Enseñar la pronunciación del inglés en un contexto de pandemia a nivel terciario se caracterizó por la ausencia de una interacción cara a cara; aunque esta interacción facilita los procesos de aprendizaje y uso oral en una lengua extranjera, las condiciones existentes en pandemia afectaron su enseñanza y disminuyeron la velocidad de internalización de esta lengua. Se hipotetiza que la aplicación de prácticas basales en la enseñanza de la pronunciación mejorará la competencia oral. Los resultados de esta investigación demuestran que (...) un periodo de entrenamiento formal permanente, continuo y evaluable aplicando las prácticas basales permiten alcanzar la competencia esperada.

Recent work on emergence in physics has focused on the presence of singular limit relations between basal and upper-level theories as a criterion for emergence. However, over-emphasis on the role of singular limit relations has somewhat obscured what it means to say that a property or behaviour is emergent. This paper argues that singular limits are not central to emergence and develops an alternative account of emergence in terms of the failure of basal explainability. As a consequence, emergence and reduction, (...) long held to be two sides of the same coin in the emergentist tradition, are largely decoupled. (shrink)

Going from cognitive theory to neural data to ACT‐R models, the authors relate brain activity in a lexical ambiguity priming task to brain processes that resolve ambiguity in word meanings. These detailed data were tested and found compatible to the results of an ACT‐R computational model of reinforcement learning (RL). The model confirms and extends the behavioral findings to provide a RL account of individual differences in lexical ambiguity resolution.

Several attempts have been made previously to provide a biological grounding for cognitive architectures by relating their components to the computations of specific brain circuits. Often, the architecture's action selection system is identified with the basal ganglia. However, this identification overlooks one of the most important features of the basal ganglia—the existence of a direct and an indirect pathway that compete against each other. This characteristic has important consequences in decision-making tasks, which are brought to light by Parkinson's disease as (...) well as genetic differences in dopamine receptors. This paper shows that a standard model of action selection in a cognitive architecture cannot replicate any of these findings, details an alternative solution that reconciles action selection in the architecture with the physiology of the basal ganglia, and extends the domain of application of cognitive architectures. The implication of this solution for other architectures and existing models are discussed. (shrink)

“Morphological computation” is an increasingly important concept in robotics, artificial intelligence, and philosophy of the mind. It is used to understand how the body contributes to cognition and control of behavior. Its understanding in terms of "offloading" computation from the brain to the body has been criticized as misleading, and it has been suggested that the use of the concept conflates three classes of distinct processes. In fact, these criticisms implicitly hang on accepting a semantic definition of what constitutes computation. (...) Here, I argue that an alternative, mechanistic view on computation offers a significantly different understanding of what morphological computation is. These theoretical considerations are then used to analyze the existing research program in developmental biology, which understands morphogenesis, the process of development of shape in biological systems, as a computational process. This important line of research shows that cognition and intelligence can be found across all scales of life, as the proponents of the basal cognition research program propose. Hence, clarifying the connection between morphological computation and morphogenesis allows for strengthening the role of the former concept in this emerging research field. (shrink)

Depue & Collins's model of incentive-motivational modulation of goal-directed behavior subserved by a medial orbital prefrontal cortical (MOC) network is appealing, but it leaves several questions unanswered: How are the stimuli that elicit an incentive motivational state selected? How does the incentive motivational state created by the MOC network modulate behavior? What is the function of the dopaminergic input to the striatum? This commentary suggests possible answers, based on the open-interconnected model of basal-ganglia-thalamocortical circuits, in which the limbic circuit selects (...) goals and, via its connections with the motor and the associative circuits, directs behavior according to those goals, elaborating on the role of dopamine.

This review summarizes recent experiments on neuronal mechanisms underlying goal-directed behaviour. We investigated two basic processes, the internally triggered initiation of movement and the processing of reward information. Single neurons in the striatum were activated a few seconds before self-initiated movements in the absence of external triggering stimuli. Similar activations were observed in the closely connected cortical supplementary motor area, suggesting that these activations might evolve through build up in fronto-basal ganglia loops. They may relate to intentional states directed at (...) movements and their outcomes. As a second result, neurons in the striatum were activated in relation to the expectation and detection of rewards. Since rewards constitute important goals of behaviour, these activitations might reflect the evaluation of outcome before the behavioural reaction is executed. Thus neurons in the basal ganglia are involved in individual components of goal-directed behaviour. (shrink)

Magnetic resonance imaging (MRI) can provide a number of measurements relevant to sport-related concussion (SRC) symptoms; however, most studies to date have used a single MRI modality and whole-brain exploratory analyses in attempts to localize concussion injury. This has resulted in highly variable findings across studies due to wide ranging symptomology, severity and nature of injury within studies. A multimodal MRI, symptom-guided region-of-interest (ROI) approach is likely to yield more consistent results. The functions of the cerebellum and basal ganglia transcend (...) many common concussion symptoms, and thus these regions, plus the white matter tracts that connect or project from them, constitute plausible ROIs for MRI analysis. We performed diffusion tensor imaging (DTI), resting-state functional MRI, quantitative susceptibility mapping (QSM), and cerebral blood flow (CBF) imaging using arterial spin labeling (ASL), in youth aged 12-18 years following SRC, with a focus on the cerebellum, basal ganglia and white matter tracts. Compared to controls similar in age, sex and sport (N = 20), recent SRC youth (N = 29; MRI at 8 ± 3 days post injury) exhibited increased susceptibility in the cerebellum (p = 0.032), decreased functional connectivity between the caudate and each of the pallidum (p = 0.035) and thalamus (p = 0.021), and decreased diffusivity in the mid-posterior corpus callosum (p < 0.038); no changes were observed in recovered asymptomatic youth (N = 16; 41 ± 16 days post injury). For recent symptomatic-only SRC youth (N = 24), symptom severity was associated with increased susceptibility in the superior cerebellar peduncles (p = 0.011) and reduced activity in the cerebellum (p = 0.013). Fewer days between injury and MRI were associated with reduced cerebellar-parietal functional connectivity (p < 0.014), reduced activity of the pallidum (p = 0.002), increased CBF in the caudate (p = 0.005), and reduced diffusivity in the central corpus callosum (p < 0.05). Youth SRC is associated with acute cerebellar inflammation accompanied by reduced cerebellar activity and cerebellar-parietal connectivity, as well as structural changes of the middle regions of the corpus callosum accompanied by functional changes of the caudate, all of which resolve with recovery. Early MRI post-injury is important to establish objective MRI-based indicators for concussion diagnosis, recovery assessment and prediction of outcome. (shrink)
