Sexual, Religious and Cultural Taboos Subtitled in American TV Shows and Movies

This study was conducted to examine subtitling into Arabic in American movies and TV shows that deal with sexual, religious and cultural taboos. This paper analyzed three episodes from the American TV show, Friends, and two episodes from animation series, The Simpsons, and three American movies, Troy, Sierra Burgess is a Loser, and The Wolf of Wall Street, to examine these issues. The analysis process was done by watching these episodes and movies, collecting the English words that have discrepancy with the Arabic subtitles, transcribing them with a short description of the relevant scenes in which they occurred, and finally considering the relationship between the original English words and the Arabic subtitles by focusing on the choice of words used in the subtitle. The study demonstrated that subtitlers generally present qualified subtitles, but when it comes to sexual, religious and vulgar contents, they tend to either euphemize or omit this content from the subtitle line. Through examining these contents, the study also showed that the subtitlers, by honoring the cultural ideologies that are found in most of the Arab societies in their subtitles, presented a discrepancy between the ideologies of the Arab culture and the ideologies of the American culture. The first was presented as a standard and idealized one, while the other was presented in any ways depraved

Direct and Indirect Effects of IQ, Parental Help, Effort, and Mathematics Self-Concept on Mathematics Achievement

This study examined the structural relationships among cognitive constructs (intelligence and achievement) and affective constructs (perceived parental help, effort and self-concept). It was proposed that the relationships are not invariant across gender. The sample consisted of 219 boys and 133 girls from elementary and preparatory public schools in Al Ain in the United Arab Emirates. Intelligence (IQ) was measured by the Test of Non-verbal Intelligence (TONI) and parental help was measured by 4-Likert-type items. Effort was measured by 4-Likert-type items. Self-concept (SC) was measured by 8-Likert-type items taken from the SDQ I (Abu-Hilal, 2000). Mathematic Achievement was the scores of students in mathematics from school records. The structural model assumed that IQ would have an effect on parental help, effort, SC and achievement. Parental help would have an effect on effort, SC and achievement. Also, effort would have an effect on SC and achievement. Finally, SC would have an effect on achievement. The structural model was tested for invariance across gender. The measurement model proved to be invariant across gender and so was the structural model. The non-constrained model indicated that the structural relationships among the variables do vary according to gender. For example, boys benefited from parental help by exerting more effort while girls did not. Boys with high IQ exerted more effort than boys with low IQ; but girls with high IQ exerted the same amount of effort as girls with low IQ. The model explained 45% and 39% of the variance in math scores for boys and girls, respectively

Ammonium ion removal using activated zeolite and chitosan

Studies have previously been done on efficacies of chitosan and zeolite in ammonium ion (NH4+) removal. However, no study compares the adsorption performance of natural zeolite and activated natural zeolite with high and low molecular weight chitosan. Hence, this study investigates the potentials of natural zeolite (NZ), activated natural zeolite (ANZ), low molecular weight chitosan (LMWC) and high molecular weight chitosan (HMWC) in NH4+ removal. The characteristics of NZ, ANZ, LMWC, and HMWC such as functional groups, surface morphology, elemental composition, zeta potential and particle size were also investigated. The deposition of NH4+ on the surface of NZ and ANZ was confirmed with the absence of nitrogen by the adsorption spectrum of EDX and supported by the presence of an FTIR stretching band at 3500-3300 cm-1, as well as broader and less intense bands 1600 cm-1 after the adsorption for all the adsorbents. The particle size of LMWC, HMWC, NZ and ANZ were 98, 813, 22354 and 9826 nm, respectively. Meanwhile, after the activation process, the composition of O, Si, Al, Fe, Ca and Na were reduced. NH4+ batch adsorption was also studied. HMWC, NZ, and ANZ reached adsorption equilibrium at 15 h, meanwhile for LMWC, the equilibrium reached at t = 20 h. The adsorption capacity of LMWC, HMWC, NZ, and ANZ at an initial concentration of 50 mg/L were 0.769 mg/g, 0.331 mg/g, 2.162 mg/g and 2.937 mg/g respectively. ANZ had the highest adsorption capacity, which might be related to the reduction of cationic elements such as Fe, Ca and Na after the activation has increased the unbalanced negative charge within the crystal lattice of ANZ that can be neutralized by NH4+ hence led to higher adsorption. HMWC has the lowest adsorption capacity that may be due it is positively charged at pH 7 which would favor the adsorption of negatively charged species instead of positively charged species, NH4+

Membrane electrode assembly with high efficiency and stability: effect of solvent type and membrane composition

Membrane electrode assembly (MEA) method is being widely considered in proton exchange membrane fuel cell (PEMFC) preparation. This work describes for the first time how PEMFC performance can be enhanced, while using relatively low temperature processing for the MEA, by choosing the suitable solvent and suitable ionomer (nafion) content. Three dispersion solvents (water, ethylene glycol and ethanol) have been examined here, and ethanol (with lowest boiling point) showed best PEMFC performance. In addition to its non-hazardous nature, the low boiling point ethanol allowed manufacturing the working membrane at 130°C or lower besides using a safe solvent to use. In each solvent system, different nafion concentrations were used (10%, 20% and 30%). The 30% nafion concentration in ethanol showed highest performance (Open circuit potential of 0.88 V and output working potential of 0.67 V at 20 mA/cm2 current density) among the series. The anode and cathode, of the MEA, were both fabricated using same catalyst material (Platinum) and same nafion sheet thickness (50 μm). The spray method was employed. The electrochemical performance for the prepared MEA fuel cells was assessed by linear sweep voltammetry to evaluate the open circuit voltage
