Coping with Information Overload: A Business Perspective

Study examines the sources and origins of information overload, its effects on knowledge workers, and its overall implications for business companies. The main argument presented in this study is that information overload is not a singular issue but that it arises out of a combination of excessive amount of both sought information and supplied information (i.e. interruptions and distractions). An empirical study conducted as a part of the research revealed that information overload is a widespread problem at modern workplace. Furthermore, the empirical research suggests that the level of perceived information overload depends on both the nature of performed work task and individual personality disposition

Pembentukan makna tatabahasa dalam struktur ayat kata kerja Kāna (كان): Formation grammar meaning of the sentence structure of the verb Kāna

Grammar plays a role in determining the meaning of a sentence. In fact, grammatical forms have a variety of meanings based on the context in which they are used. The study of grammar involves examining the function carried out by a single word. This study was conducted to identify the grammatical meaning that exists in the use of Verbal Phrase Predicate (PFK) for kāna verb (KKK) in Arabic sentence structure (BA) and describe the appropriate match for the grammatical meaning that exists in Malay sentence structure (BM). This study was conducted using qualitative method based on library method (text analysis study) in analyzing data. The researchers obtain reference books and scholarly resources as well as reviews past studies related to the research topic to obtain appropriate reference sources. The theoretical framework utilized in this study includes the grammatical meanings inherent in the use of PFK for KKK in the BA sentence structure by al-Sāmirrā’ī (2003) and the component analysis model by Nida (1975) which analyzes the meaning of KKK grammatical references. While the contrastive analysis carried out involves the grammatical meaning contained in the use of KKK in the BA sentence structure and matching the appropriate grammatical meaning in the BM sentence structure. The results of the study found that different grammatical meanings are formed based on the time aspect found in the PFK for KKK in the sentence structure of BA. The results of this study also prove the appropriate match for the grammatical meaning that exists in the BM sentence structure is the verb which consists of aspect auxiliary verbs, variety auxiliary verbs and adverbs. Therefore, translators need to consider the meaning of this grammar in the translation process, so that the matching of the translated meaning is accurate and correct

Sintesis dan pencirian getah asli cecair terhidrogen untuk adunan polimer

Sistem hidrazin hidrat/hidrogen peroksida (HH/H2O2) digunakan untuk menjana sumber hidrogen bagi tujuan penghidrogenan getah asli cecair (LNR) melalui penghasilan diimida. Spesies diimida yang terhasil akan membekalkan sumber hidrogen kepada ikatan karbon ganda dua dalam rantai polimer LNR. Getah asli cecair terhidrogen (HLNR) yang terhasil menunjukkan ciri lebih tahan suhu berbanding LNR. Suhu degradasi HLNR didapati meningkat pada 435°C berbanding LNR iaitu pada 381°C. HLNR seterusnya dijadikan pengserasi dalam penghasilan adunan polimer polistirena/getah asli, PS/NR/HLNR (60/35/5). Kekuatan regangan dan impak PS/NR masing-masing meningkat sebanyak 70.7% dan 149.6% setelah HLNR ditambah sebagai pengserasi dalam adunan. Beberapa pemerhatian morfologi melalui mikroskop optik dan SEM turut menyokong kesan penyerasian adunan PS/NR dengan HLNR

Rewards Satisfaction, Perception about Social Status and Commitment of Nurses in Pakistan

This research is undertaken to approve or reject the general perception of masses about commitment of employees and to identify those factors, which effect commitment of employees in general and of nurses in particular. In previous research of Allen and Myere (1990), the factor of social status was not addressed. In this study target audience is nurses. Whereas, it is a proven fact that psychological perception effects individual’s attitudes and behaviors, so to see that how satisfaction with rewards/ benefits and perception about social status effect commitment of employees, this research was undertaken. Satisfaction level varies from person to person. The empirical results have proved that commitment of employees is affected due to satisfaction with rewards/ benefits and perception about social status

Convection Heat Transfer from Heated Thin Cylinders Inside a Ventilated Enclosure

Experimental study was conducted to determine the effect of velocity of axial fan, outlet vent height, position, area, and aspect ratio (h/w) of ventilated enclosure on convection heat transfer. Rectangular wooden ventilated enclosure having top and front transparent wall was made up of Perspex for visualization, and internal physical dimensions of box were 200 mm × 200 mm × 400 mm. Inlet vent was at bottom while outlet vents were at the side and top wall. Electrically heated cylindrical heat source having 6.1 slenderness ratio was fabricated and hanged at the centre of the enclosure. To calculate heat transfer rates, thermocouples were attached to the inner surface of heat source with silica gel. Heat source was operated at constant heat flux in order to quantify the effect of velocity of air on heat transfer. It was observed that average Nusselt number was increased from 68 to 216 by changing velocity from 0 to 3.34 m/s at constant modified Grashof number i.e. 5.67E+09. While variation in outlet height at the front wall did not affect heat transfer in forced convection region. However, Nusselt number decreased to 5% by changing the outlet position from top to the front wall or by 50% reduction in outlet area during forced convection. Mean rise in temperature of enclosure increased from 8.19 K to 9.40 K by increasing aspect ratio of enclosure from 1.5 to 2 by operating heat source at constant heat flux i.e. 541.20 w/m2

Experimentation on Optimal Configuration and Size of Thin Cylinders in Natural Convection

In this paper, an experimental study of laminar, steady state natural convection heat transfer from heated thin cylinders in an infinite air medium has been reported. Two electrically heated cylinders having the same slenderness ratio (L/D) i.e. 6.1 but different diameters i.e. 3.8 cm and 5.08 cm were used. 105 experiments were carried out to study the effect of diameter and inclination angle of thin cylinder on natural convection heat transfer. After mandatory corrections of radiation and endcap heat losses, convective heat transfer results were presented in the form of local and average dimensionless numbers. For vertical configuration of thin cylinder, Nusselt number was varied from 52.99 to 95.10 corresponding to 1.28×108≤Ra*L≤1.08×1010. While for horizontal configuration,Nusselt number was varied from 10.74 to 17.78 corresponding to 9.42×104≤Ra*D≤8.17×106. Results were compared with the published data and found satisfactory as the maximum percentage difference was only 3.09%. The essence of research is that the heat transfer coefficient increases with decrease in diameter and increase in inclination angle. Smoke flow visualization was done to capture patterns of fluid flow. Finally, comparison was made to quantify increase in Nusselt number from slender cylinder as compared to the flat plate
