Number processing of Arabic and Hebrew bilinguals: Evidence supporting the distance effect

In the current study, a direct assessment of the effect of language lexical‐syntactic structure and magnitude semantic access on numerical processing was made by contrasting the performance of Arabic/Hebrew bilinguals in a digital (Hindi‐digits/Arabic‐digits) and verbal numerical comparison task (Arabic, an inverted language: Units‐Decades, Hebrew, a non‐inverted language: Decades‐Units). Our data revealed in the digital presentation format (Experiment 1) a regular distance effect in Arabic language‐Hindi digits and Hebrew language‐Arabic digits, characterized by an inverse relation between reaction times and numerical distance with no difference in the mean reaction times of participants in Arabic‐L1 and Hebrew‐L2. This indicates that both lexical digits of two‐digit numbers in L1 and L2 are similarly processed and semantically accessed. However in the verbal presentation format (Experiment 2) a similar pattern of distance effect was found, but the mean reaction times in Arabic were lower than in Hebrew in each numerical distance. This indicates that the processing of two‐digit number words in L1 and L2 is semantically accessed and determined by the syntactic structure of each language.     

Religious Commitment,Attitudes Toward Suicide,and Suicidal Behaviors Among College Students of Different Ethnic and Religious Groups in Malaysia

The variation in suicide patterns across ethnic groups with different religious background is a puzzling social phenomenon. This study sought to examine the impact of religious commitment and attitudes toward suicide on suicidal behaviors of college students across major ethnic and religious groups in a multicultural society of Malaysia. A total of 139 college students completed Religious Commitment Inventory-10, Attitudes Toward Suicide Scale, and Suicidal Behavior Questionnaire-Revised. Findings showed significant discrepancies in attitudes toward suicide, but not suicidal behaviors across ethnic and religious groups. Suicide acceptance significantly affected suicidal behaviors as well. Although religious commitment is not associated with suicidal behaviors, its deviation is reflected in students’ acceptance of suicide. Additionally, college students’ suicide risk, lifetime, and recent suicide ideation, as well as their likelihood of future suicide attempt can be associated with their acceptance of suicide. The influence of attitudes toward suicide and religion, therefore, should be taken into consideration while implementing suicide prevention programs as it helps shape the norms about suicide among youths.     

Left-hemisphere activation is associated with enhanced vocal pitch error detection in musicians with absolute pitch

The ability to process auditory feedback for vocal pitch control is crucial during speaking and singing. Previous studies have suggested that musicians with absolute pitch (AP) develop specialized left-hemisphere mechanisms for pitch processing. The present study adopted an auditory feedback pitch perturbation paradigm combined with ERP recordings to test the hypothesis whether the neural mechanisms of the left-hemisphere enhance vocal pitch error detection and control in AP musicians compared with relative pitch (RP) musicians and non-musicians (NM). Results showed a stronger N1 response to pitch-shifted voice feedback in the right-hemisphere for both AP and RP musicians compared with the NM group. However, the left-hemisphere P2 component activation was greater in AP and RP musicians compared with NMs and also for the AP compared with RP musicians. The NM group was slower in generating compensatory vocal reactions to feedback pitch perturbation compared with musicians, and they failed to re-adjust their vocal pitch after the feedback perturbation was removed. These findings suggest that in the earlier stages of cortical neural processing, the right hemisphere is more active in musicians for detecting pitch changes in voice feedback. In the later stages, the left-hemisphere is more active during the processing of auditory feedback for vocal motor control and seems to involve specialized mechanisms that facilitate pitch processing in the AP compared with RP musicians. These findings indicate that the left hemisphere mechanisms of AP ability are associated with improved auditory feedback pitch processing during vocal pitch control in tasks such as speaking or singing.     

Respecting religion in youth music subcultures: inclusivity,individuality and conflict avoidance strategy

Drawing on fieldwork with young Evangelical and Pentecostal Christians involved in the secular punk rock subculture, this article examines strategies for building respectful relationships between religious and irreligious young people in youth music subcultures. Although punk rock developed as a secular and often anti-religious youth subculture, and although a thriving Evangelical subculture has developed with its own popular music scenes at odds with secular values, a significant number of young Christians have become active participants in punk. Arguing for the importance of musical and subcultural identities among contemporary youth, this article analyses examples of creative inclusivity and respectful relationships across religious boundaries, as well as examples of conflicts over spiritual values. Outlining strategies for building religious inclusivity and resolving religious conflict in youth subcultures, it is shown that where young people’s creative capacities and individual autonomy are respected and enabled by subcultural peers and secular or religious youth workers and institutions, strongly held religious views can still be welcomed within even strongly secular youth subcultures.     

Optical characterization of spin-coated cobalt porphyrazine thin films: effect of annealing temperature

Cobalt porphyrazine thin films were prepared by the spin-coating technique. The coated substrates were annealed at different temperatures (373, 423 and 523 K). The optical properties of the films were investigated by measuring the transmittance and reflectance spectra. The refractive index, extinction coefficient, optical band gap, dielectric constant values and thickness of the films were determined. Results showed that the refractive index, the extinction coefficient and the dielectric constants increased on annealing the films at 373 K in comparison with films annealed at other temperatures. On the other hand, the values of the band gap energy and thickness of the annealed film at 373 K were found to be the lowest in comparison with films annealed at different temperatures.     

Christian hip hop as pedagogy: a South African case study

Drawing on interviews with creators of Christian hip hop music in South Africa, this article demonstrates that this genre of popular music and youth culture is utilised as a form of pedagogy to transmit religious beliefs and values to contemporary youth. The pedagogical aspects of hip hop have been recognised in research on the topic, but the religious pedagogical uses of hip hop have been under-analysed within the social sciences. After outlining the global development of hip hop as a pedagogical practice, this article will demonstrate that, under the influence of North American Evangelicalism, South African Christian hip hop attempts to promote Evangelical orthodoxy and orthopraxy in response to the secular and religious practices of South African youth.     

Evidence-based strategies to support children’s emergent literacy in the Gulf Cooperation Council (GCC) countries

This study was designed to examine teachers’ reported use of evidence-based strategies to support children’s emergent literacy in Arab countries of the Gulf Cooperation Council (GCC). The study participants comprised 644 kindergarten teachers from four countries, including Saudi Arabia (n = 154), Qatar (n = 105), United Arab Emirates (UAE) (n = 190), and Oman (n = 195). The researchers designed a 29-items questionnaire that addressed five dimensions, examining evidence-based strategies that support emergent literacy: phonological awareness, knowledge and understandings of books and other texts, print awareness, knowledge of letters and words, and early writing. The results showed that teachers reported higher use of strategies concerning knowledge of letters and words, followed by those concerning print awareness. In addition, they reported lower use of strategies concerning early writing. Moreover, teachers in the UAE reported higher use of strategies in support of emergent literacy followed by teachers in Qatar and Oman, whereas teachers in Saudi Arabia reported lower use of evidence-based strategies. Finally, statistically significant differences were found regarding teachers’ use of emergent literacy strategies due to teachers’ demographic background. Implications for future research are discussed, and they include highlighting evidence-based emergent literacy strategies in early years settings in the GCC countries as well as expanding the scope of the study to include samples from different contexts.

Microstructural evolutions and hardness during heat treatment of Al64Cu20Fe12Si4 quasicrystal alloy

The microhardness and microstructural characteristics and subsequent heat treatment of conventionally solidified Al₆₄Cu₂₀Fe₁₂Si₄ quasicrystal were investigated by X-ray diffractometry (XRD), scanning electron microscopy (SEM) together with energy dispersive spectroscopy (EDS), differential thermal analysis (DTA), and Vickers microhardness tester. XRD analysis indicated that the conventionally solidified samples showed a quasicrystalline icosahedral phase (i-phase) together with cubic β-AlFe, tetragonal θ-Al₂Cu, and monoclinic λ-A₁₃Fe₄ crystal phases. However, the i-phase together with cubic β-AlFe and monoclinic λ-A₁₃Fe₄ phases observed heat threaded samples. As-cast and subsequently heat-treated quasicrystal samples were measured using a microhardness test device. Vickers microindentation tests were carried out on the heat-treated quasicrystal samples with the load ranging from 1 to 500?mN at room temperature. The melting point of the i-phase was determined as 900°C by DTA examinations.
