An integrated, multiparametric flow cytometry chip using ��microfluidic drifting�� based three-dimensional hydrodynamic focusing

In this work, we demonstrate an integrated, single-layer, miniature flow cytometry device that is capable of multi-parametric particle analysis. The device integrates both particle focusing and detection components on-chip, including a “microfluidic drifting” based three-dimensional (3D) hydrodynamic focusing component and a series of optical fibers integrated into the microfluidic architecture to facilitate on-chip detection. With this design, multiple optical signals (i.e., forward scatter, side scatter, and fluorescence) from individual particles can be simultaneously detected. Experimental results indicate that the performance of our flow cytometry chip is comparable to its bulky, expensive desktop counterpart. The integration of on-chip 3D particle focusing with on-chip multi-parametric optical detection in a single-layer, mass-producible microfluidic device presents a major step towards low-cost flow cytometry chips for point-of-care clinical diagnostics.     

Pre-service special education teachers’ professionalism and preparation in terms of child sexual abuse

This study aimed at examining Jordanian pre-service special education teachers’ professionalism and preparation on the topic of child sexual abuse (CSA). Qualitative research data from interviews with 20 pre-service special education teachers were analysed using thematic analysis. The results showed that these participants generally hold avoiding behaviour toward speaking about CSA as it is an unspoken taboo. Participants also hold low levels of professionalism on the topic of CSA. The results also demonstrate that they felt that their preparation programme is inadequate and desired more content and pedagogy courses that relate to CSA. Implications and recommendations are presented in light of the study findings.     

Negotiating class,ethnicity and modernity: the ‘Malaynisation’ of P. Ramlee and his films

Early Malaysian national cinema disseminates a social reconstruction process aimed at reconstructing Malay supremacy at the centre of a specific geographical, political, economic and cultural space. Aptly termed as ‘Malaynisation’, this process occurred during the Golden Age of Malaysian cinema through the films of P. Ramlee. While existing as a capitalist film culture located within an ethnically diverse society, early Malaysian cinema through Ramlee have produced a significant number of mono-ethnic representations solely focused on the culture, language and lifestyles of the Malays. As such, the articulation of the politics of inclusion and exclusion in Ramlee’s films articulates a right-wing nationalist sentiment that upholds the sovereignty of the dominant Malays while undermining other ethnic communities. The nature of these representations enunciates the context of an ‘imagined community’ which locates the formation of a particular type of nationalism within a social, political and cultural communicative space. This paper examines the construction of the ‘modern Malay’ identity in Ramlee’s films and the nationalist discourse in Ramlee’s films as an attempt at producing the idea of a nation as a continuous narrative of national progression by presenting the postcolonial Malays as a modern, successful and dominant force.     

The impact of organizational factors on management information system success: An investigation in the Iran's agricultural extension providers

Information system success has been widely discussed in the past two decades. As systems and technologies are being improved and developed, discussions on their effectiveness and evaluation on their success have been continuously debated by researchers, scholars and practitioners throughout the years. Besides the major concern of IS effectiveness, factors influencing IS effectiveness are also important. One of these factors is the organizational factor. Using perceptual measures, this study aims to investigate the influence of organizational factors on MIS success. Survey questionnaires were gathered from 132 Extension Managers from Iran's Agricultural Extension Providers. Seven items were identified to influence MIS success. They are IS department structure, top management support, management style, managerial IT knowledge, goal alignment, resources allocation and IS infrastructure. The study also identified five MIS success dimensions; systems quality, information quality, perceived Ease of use, organizational impact and individual impact. The study found that the MIS success variables are significantly and highly correlated. The study also found all the organizational factors are significantly correlated to the five IS success factors investigated; the system quality, information quality, perceived ease of use, organizational impact and individual impact. Multiple regression analyses also found goal alignment as the highest predictor of IS success, followed by IS department structure, IS infrastructure and management style.     

Physiological characteristics of elite and sub-elite badminton players

Abstract

The aims of this study were to establish the physical and physiological attributes of elite and sub-elite Malaysian male badminton players and to determine whether these attributes discriminate elite players from sub-elite players. Measurements and tests of basic anthropometry, explosive power, anaerobic recovery capacity, badminton-specific movement agility, maximum strength, and aerobic capacity were conducted on two occasions, separated by at least one day. The elite (n = 12) and sub-elite (n = 12) players' characteristics were, respectively: mean age 24.6 years (s = 3.7) and 20.5 years (s = 0.7); mass 73.2 kg (s = 7.6) and 62.7 kg (s = 4.2); stature 1.76 m (s = 0.07) and 1.71 m (s = 0.05); body fat 12.5% (s = 4.8) and 9.5% (s = 3.4); estimated VO_2max 56.9 ml · kg^?1 · min^?1 (s = 3.7) and 59.5 ml · kg^?1 · min^?1 (s = 5.2). The elite players had greater maximum absolute strength in one-repetition maximum bench press (P = 0.015) compared with the sub-elite players. There were significant differences in instantaneous lower body power estimated from vertical jump height between the elite and sub-elite groups (P < 0.01). However, there was no significant difference between groups in shuttle run tests and on-court badminton-specific movement agility tests. Our results show that elite Malaysian male badminton players are taller, heavier, and stronger than their sub-elite counterparts. The test battery, however, did not allow us to discriminate between the elite and sub-elite players, suggesting that at the elite level tactical knowledge, technical skills, and psychological readiness could be of greater importance.     

The English Translation of Arabic Puns in the Holy Quran

The pun is a tricky use of a word or phrase which has very different meanings that are closely interrelated, or of words with the same sound but different meanings. The Pun is a term with a dual meaning: “close” using obvious reference, and “far” using obscure reference. The hidden is usually meant. The close meaning is the sooner that comes to the listener’s mind. However, the speaker targets at the far one yet use the close to hide it. Translating the Quran text always raises several serious challenges in translation; these challenges are due to the different translations of puns and the misinterpretations between the intended meanings of a pun with their basic concepts, which could result in a certain amount of ambiguity. The study examines the Quranic corpus and its three versions of English translations. The study utilizes the typology of Delabastita?s for horizontal puns, Nida’s techniques of dynamic and formal equivalent and Newmark’s translation methods. This research attempts to investigate the semantic meaning of puns in the Quran translation and to define the translation techniques applied in translating the Quranic puns from Arabic into English.     

Peranan bahasa dalam kebudayaan

Bahawa “bahasa” dalam pengertian orang-orang Melayu tidaklah semata-mata bersifat lingual (yang hanya menjadi alat komunikasi antara dua pihak pengguna bahasa sahaja); tetapi bahasa itu adalah lebih kultural (yang menjadi pengilham dan pendorong manusia ke tahap lebih baik dalam hidupnya; sekaligus mempertinggi kebudayaan manusia itu).     

Broadcast diamond channel: Transmission strategies and bounds

This paper proposes a new multiuser communication model in which a source with broadcast capabilities wants to transmit two different messages to two different destinations in the case that no direct links between the source and its destinations. In this channel model, two parallel half-duplex relays are used to extend the transmission. For this communication model, an outer bound to the achievable capacity is initially derived. Then, two distinctive transmission schemes are characterized such that the source can transmit to the two destinations. In each scheme, the transmission is split into two phases. Specifically, in the first phase, the source can broadcast different messages to the two relays. Then, in the second phase, the two relays can forward the source’s signals into their destinations. Based on the transmission on each scheme, the achievable rate region is characterized. Further, we derive the optimal duration of each phase. The theoretical analyses are followed by many numerical examples that compare between the different transmission techniques and also show the points at which the capacity is achieved.
