Today's educational system increasingly integrates digital devices such as laptops and tablets in the classroom on the assumption that the use of these technologies will increase student motivation ...and learning. However, research shows that students often use technologies for distractive purposes like off-task activity and multitasking. Few studies address the processes involved in this activity. This article offers a postphenomenologically informed qualitative study of students' off-task use of technology during class. Building on interviews with students in a Danish business college about their off-task technology use, findings suggest that off-task activity is not always a conscious choice. Because of deeply sedimented bodily habits, students often experience habitual distraction in the form of prereflective attraction towards certain frequently visited websites (e.g., Facebook). Laptops are experienced as endowed with an attractive allure that "pulls you in". Students sometimes go as far as closing the lids of their laptops to avoid this habitual distraction. Theoretical and practical implications are discussed.
It is well known that norms influence behavior. Beyond simply shaping what people do, we argue that norms constrain what behaviors even come to mind as options, effectively excluding counternormative ...behaviors from consideration. We test this hypothesis across five primary and multiple supplementary studies using diverse methods (Ntotal = 5,488). In Study 1, people reported that behaviors that were counternormative in a situation, even behaviors that could satisfy a motivational drive, were far less likely to come to mind and less desirable than behaviors that were norm-consistent. Going beyond self-report measures, Studies 2a-2c found that people even misrepresented norm-violating behaviors as "impossible," suggesting they are not considered. Using a change-blindness paradigm, Study 3 found that people were less likely to track changes in goal-relevant objects that would be counternormative (vs. normative) to engage with. Studies 4 and 5 explored implications for problems of temptation and self-control. Study 4 found that members of a clinical population striving to eat healthier reported that the very same unhealthy but tasty food items would be less tempting and would trigger less self-control conflict if they encountered the food in a context where its consumption would be counternormative (vs. normative). Study 5, a field study, shows that introducing a norm prohibiting laptop use in class reduced students' temptation to multitask (as well as actual multitasking) over the term, whereas encouraging individual self-control did not. Discussion addresses how norms can be harnessed to lighten the burdens of temptations and help people achieve their goals.
In this direct replication of Mueller and Oppenheimer’s (2014) Study 1, participants watched a lecture while taking notes with a laptop (n = 74) or longhand (n = 68). After a brief distraction and ...without the opportunity to study, they took a quiz. As in the original study, laptop participants took notes containing more words spoken verbatim by the lecturer and more words overall than did longhand participants. However, laptop participants did not perform better than longhand participants on the quiz. Exploratory meta-analyses of eight similar studies echoed this pattern. In addition, in both the original study and our replication, higher word count was associated with better quiz performance, and higher verbatim overlap was associated with worse quiz performance, but the latter finding was not robust in our replication. Overall, results do not support the idea that longhand note taking improves immediate learning via better encoding of information.
This paper proposes a multiple‐input multiple‐output (MIMO) antenna design with 3‐port excitation. The antenna has a ground size of 260 × 200 mm2 and a portion size of 60 × 10 × 0.8 mm3. The design ...of the MIMO antenna is achieved using two inverted F‐type coupled‐fed monopole antennas and a loop antenna acting as an isolation element. The third antenna is designed as the isolation element, and acts not only as an isolation element to improve the mutual coupling between two antennas operating within the LTE 2300/2500/WLAN 2.4 GHz/5G C‐band, but also a radiator operating in the 5G C‐Band (3.4‐3.6 GHz). Such 3‐port MIMO antennas can be achieved by properly selecting the dimensions of the antennas and isolation element. The two coupled‐fed monopole antennas are operating in the LTE 2300/LTE 2500/WLAN 2.4/5G C‐Band bands, and the third antenna operates in the 5G C‐Band.
A concern that has been raised with the transition from pen and paper examinations to electronic examinations is whether this will make cheating easier. This article investigates how teachers and ...students perceive the differences in ease of cheating during three types of written examination: paper exams, bring your own device e-exams and e-exams using university-owned devices. It also investigates perceptions about the effectiveness of some typical countermeasures towards cheating across these examination types. A mixed-method approach was used, combining questionnaires and interviews with students and teachers in the authors' own university. A total of 212 students and 162 teachers participated in the questionnaire survey, and then, a more limited number were interviewed to get a deeper understanding of the results. Six-different cheating practices were considered - impersonation, forbidden aids, peeking, peer collaboration, outside assistance and student-staff collusion and seven different countermeasures were considered - proctors, biometry, mingling, shuffling, random drawing, sequencing and broadcasting. Both students and teachers perceived cheating as easier with e-exams, and especially with bring your own device. They also thought some countermeasures would be easier to implement with e-exams.
PURPOSE: A generic hotspot assessment of social impacts from a product was conducted, using a laptop computer as a case. The aims of the case study were to identify social hotspots of the laptop and ...to test and evaluate the methodology. METHODS: The case study was based on the social LCA methodology described in the Guidelines for social LCA and included the product system from ‘cradle to grave’ as well as the impacts on all relevant stakeholders. We focused on a simplified list of materials and used mainly country-specific data. RESULTS AND DISCUSSION: A new method for impact assessment of hotspots was developed. The total activity in each phase was distributed among countries. The countries were divided into groups related to the extent of activity in the product system, as well as to their performance on a subcategory. High values in both groups were highlighted and hotspots were identified. The results revealed some hotspots, some hot countries and some hot issues, all indicating a risk of negative social impacts in the product system of a laptop. It also identified workers and the local community as the stakeholders most at risk of negative social impacts. Among the hotspots identified, the following subcategories were of importance: safe and healthy living conditions, social benefit/social security, access to material resources, involvement in areas with armed conflicts, community engagement (lack of), corruption, and access to immaterial resources. CONCLUSIONS: The study showed it is possible to conduct a social LCA on a generic complex product using the Guidelines, even though data collection was impaired by lack of data and low data quality. It identified methodological issues that need further attention, for example the indicator impact pathways. Still, it is clear that new insights can be gained by social LCA, where the life cycle perspective and the systematic approach help users identify potentially important aspects that could otherwise have been neglected.
The use of computers has been shown to have the potential for detrimental effects on the musculoskeletal system. Previous research has identified risk factors for computer-related musculoskeletal ...symptoms (MSS) in the workforce, but the focus of investigation on university students is comparatively recent. There appears to be a relative paucity of research into computer-related MSS in European universities and none to date in Ireland. The primary aim of this study was to determine the prevalence of computer-related MSS in a cohort of undergraduate university students in Ireland. The cross-sectional study design involved a questionnaire of two parts. Part A was a questionnaire adapted from previously used questionnaires and included questions relating to demographic information regarding age, gender, year of study, hand dominance and details of computer use. Part B was a modified (to include only computer-related symptoms) Nordic Musculoskeletal Questionnaire. A total of 312 Health Sciences students were surveyed and 241 responded, giving an overall response rate of 76.9%. All students used a computer, with 95.4% using a laptop. Although the reported duration of computer use was quite low, the prevalence of computer-related MSS was high (52.8%). Increased prevalence of MSS was significantly associated with year of college, average daily laptop use and right hand dominance. A considerable proportion of students reported that MSS impacted on their work (18.3%) and leisure activities (23.6%) and furthermore 17.1% sought medical attention. The current study suggests that further research should be carried out on students from other disciplines and on students in other European universities to facilitate a greater understanding of the risk factors for computer-related MSS in undergraduate students.
•All students used computers, laptop more than desktop.•The prevalence of computer-related MSS was high.•MSS prevalence increased significantly year-on-year.•MSS were significantly associated with daily computer use and hand dominance.•Computer-related MSS impacted on students lives.
Multimodal transportation is a key component of modern logistics systems, especially for long-distance transnational transportation. This paper explores the various alternative routes for laptop ...exports from Chongqing, China to Rotterdam, the Netherlands. It selects seven available routes for laptop transportation from Chongqing to Rotterdam. The multimodal model was adopted to demonstrate alternative routes using various factors such as transport cost, transfer cost, transit time, transport distance, document charge, port congestion surcharge, customs charge, confidence index and so on. Among possible alternative routes, the results indicate that the route 6 was the fastest routes except for the air transport (route 7), while the route 1 was the cheapest and safest way. Nonetheless, route 1 may be not suitable for the laptop transport due to the importance of timeliness. The logisticians may able to utilize this research's findings to make a balance between transit time and transport cost for effective multimodal transport of laptops from Chongqing to Rotterdam.
Laptop is a desktop personal computer (PC) whose dimensions are reduced to increase flexibility in its use. However, the large number of products will make it difficult for consumers to choose a ...laptop that suits the needs of consumers who want to buy it.The purpose of this research is to help buyers who want to buy laptop products according to their needs by making a Decision Support System (DSS). There are 12 criteria considered in this research, price, processor, RAM capacity, hard disk capacity, SSD capacity, V-RAM capacity, maximum RAM upgrade capacity, laptop weight, screen size, screen type, screen refresh rate, and screen resolution. Choosing a laptop product there is a criterion value of a laptop product and a value of preference criteria from the buyer as a decision maker. Also the criteria values on laptop products have different contributions to the overall value of the laptop product. Thus, the methods used are Analytical Hierarchy Process (AHP), Profile Matching (PM) with linear interpolation, and Simple Addictive Weighting (SAW) to determine the recommended options. Lastly, SPK that has been made will be able to provide recommendations best alternative choices and best suit the needs of buyers for selecting laptop products.
This study investigated the effects of note-taking styles on college students' learning achievement and cognitive load in a 6-week lecture-based computer network course. Fortytwo students were ...randomly assigned into one of three groups, which consisted of collaborative note-taking, laptop note-taking, and traditional longhand note-taking. The results showed that students in the collaborative note-taking group did better on learning achievement and cognitive load than students in the other two groups. Particularly, students in the collaborative note-taking group had a significantly higher rate of learning achievement and a significantly lower level of extraneous load than students in the longhand note-taking group.
