How Persuasive Are Health Advertisements in First-Person Shooter Games? Exploring Knowledge-Activation and Thought-Disruption Mechanisms

This study examined whether persuasive health messages embedded in shooter games have broad or targeted effects on players’ willingness to engage in risk behaviors (N = 145). Participants presented with in-game health messages discouraging alcohol-impaired driving of motor vehicles showed reduced willingness to drink alcohol and to operate both motor and nonmotor vehicles, compared to those in a no-message gaming control condition. There were no spillover effects on willingness to smoke cigarettes or marijuana, thus implying targeted persuasive effects. In addition, players experiencing high instead of low cognitive load showed decreased postexperiment willingness to drink and operate nonmotor vehicles, thus suggesting that playing a game under high cognitive load can influence players’ attitudes. The findings replicate previous research and further expand on knowledge-activation and thought-disruption mechanisms underlying the persuasiveness of health messages.     

Financing higher education in Pakistan

A recent shift in the allocation of public expenditure towards higher education prompts several questions: Is this allocation economically justified? Are these resources well utilized? Is there significant cost recovery of these expenditures? If not, who benefits from the subsidy these expenditures represent? Are there alternative means of financing higher education? This paper attempts to provide answers to these questions, which can be briefly summarized as follows: Estimates of social rates of returns do not support the reallocation of public expenditures away from primary towards higher education; low retention rates and high failure rates suggest that the internal efficiency in the utilization of these expenditures is low; currently, almost all public expenditures on higher education represent a subsidy; given the tax burden and enrollment ratios by income group, the lower income groups seem to be gaining most from these subsidies; a start has been made at private sector higher education with the opening of two professional universities, but the prospects of general universities currently opening appears to be dim. Pakistan has a well designed loan program in operation although its quantitative impact is currently limited.     

Urinary iodine levels in three ecological zones of Bangladesh

Urinary iodine levels in children (5–11 years) and in adult males and females (15–44 years) of three ecological zones (hilly, flood-prone and plains) of Bangladesh were analyzed to determine the status of biochemical iodine deficiency in the country. Data indicated that a large majority of the population all over Bangladesh have biochemical iodine deficiency urinary iodine excretion (UIE) less than the accepted cut-off level of 10 μg/dl. Adults were deficient to comparable degrees, 31.3% severely iodine deficient. The flood-prone zone was less affected: 71.7% children had iodine deficiency and 25% were severely deficient. Adults of this zone were less affected than the children. Iodine deficiency was least severe in the plain zone: 59.8% children were biochemically iodine deficient and of them 23.4% had UIE less than 2.0 μg/dl. In the case of the adults of this zone, 60.8% were biochemically iodine deficient and 20.6% had severe iodine deficiency. The results indicate that Bangladesh as a whole is an iodine deficient region, with the hilly zone being the most severely affected. Children were slightly more affected than the adults, and females were more affected than the males.     

Qualitative and quantitative analysis of goat ovaries,follicles and oocytes in view of in vitro production of embryos

Goat ovaries were collected from the slaughterhouse and categorized as right, left, corpus luteum （CL）-present and -absent group and evaluated on the basis of weight （g）, length （cm）, width （cm）, number of follicles, follicles aspirated and number and state ofcumulus-oocyte-complexes （COCs）. Comparatively higher weight [（0.66±0.02） vs （0.64±0.02） g], length [（1.17±0.02） vs （1.1 ±0.02） cm] and width [（0.77±0.02） vs （0.74±0.02） cm] were found in right ovaries than those of left. On the other hand significantly （P〈0.05） higher weight [（0.71±0.03） vs （0.64±0.01） g] and width [（0.76±0.03） vs （0.75±0.01） cm] were found in CL-present group than those of CL-absent group of ovaries. The left ovaries contained comparatively higher number of normal COCs [（1.06±0.09） per ovary] than fight ovaries [（1.03±0.10） per ovary] and the similar trend was found in total number of follicles [（4.51±0.25） vs （4.30±0.23） per ovary] and follicles aspirated [（2.55±0.14） vs （2.52±0.12） per ovary]. But the total COCs per ovary was almost similar in both ovaries [right and left： （1.85±0.12） and （1.85±0.11） per ovary, respectively]. Higher number of total COCs [（1.87±0.09） vs （1.76±0.16） per ovary], total number of follicles [（4.45±0.19） vs （4.16±0.37） per ovary], follicles aspirated [（2.55±0.10） vs （2.48±0.21） per ovary] and normal COCs [（1.12±0.07） vs （0.76±0.14） per ovary] were found in CL-absent group than those of CL-present group of ovaries.     

Does immigration background matter? How teachers’ predictions of students’ performance relate to student background

Accurate teacher evaluations of student performance are crucial for effective teaching. This study examined whether students’ immigration and language background affect teachers’ evaluations. Multilevel analyses tested whether teachers overestimate the performance of immigrant relative to that of non-immigrant students. As part of the German PISA 2003 assessment, 305 teachers predicted the performance of seven of their students on two mathematics problems of different linguistic complexity. Results revealed an interaction effect of students’ language background and linguistic complexity of the problem on teachers’ predictions. Teachers overestimated the performance of bilingual students more than the performance of monolingual immigrant or non-immigrant students on a linguistically complex problem. Teachers need to consider both students’ language background and linguistic demands of the material used to appropriately support bilingual students.

Use of digital game based learning and gamification in secondary school science: The effect on student engagement,learning and gender difference

This study aimed to identify the impact of a game based learning (GBL) application using computer technologies on student engagement in secondary school science classrooms. The literature reveals that conventional Science teaching techniques (teacher-centered lecture and teaching), which foster rote learning among students, are one of the major concerns in Pakistan Education system. This leads to student disengagement in science lessons eventually resulting in student absenteeism and dropouts from the schools. This study consisted of five stages: (1) examining the impact of Digital Game-Based Learning (DGBL) and gamification on engagement, learning and gender difference, and literature related to using DGBL models for instructional design; (2) planning learning activities and developing a GBL application based on a specific content in Science; (3) conducting an intervention with a sample of 72 participants of 8th grade (aged 12–15) in a low cost private school of Pakistan following quasi-experimental research framework; (4) observing behaviour and emotions of the participants during science lessons; (5) conducting pre and post tests to assess the learning outcomes of participants followed by focus groups discussion. Analysis from Friedman test, Mann-Whitney U test, and Wilcoxon Signed Rank test show that the GBL application has a positive influence on student engagement. However, GBL application was not equally effective for all students since girls outperformed boys in terms of engagement and learning outcomes. This study gives insights into the development of better educational games to promote student learning.
