“…1 1 Flows of electronics goods such as computer, semiconductors, and cellphones have proven difficult to model (Gruber et al, 2016). Cellphones and semiconductors have proven especially difficult because so much of the value-added comes from imported parts and components (see, e.g., Carton, Mongardini, & Li, 2018, and Cheung et al, 2012). We thus exclude cellphones and semiconductors from our estimation. We use the four leading exporting countries to avoid using countries that did not trade much with each other over part of the sample period, because these trading partners can have large percentage changes in trade due to idiosyncratic factors such as a trading company opening up a new branch rather than due to macroeconomic variables such as real exchange rates and real income.…”

Does a country’s export structure impact the way that exchange rates affect trade? Do more sophisticated products exhibit lower demand elasticities? Using panel data for major exporters over the 1992–2016 period and dynamic ordinary least squares techniques, we find that price elasticities are higher for low-technology goods such as textiles and footwear than for high-technology goods such as pharmaceuticals and medical equipment. We also find that elasticities are larger for less advanced countries such as China than for more advanced countries such as Switzerland. We draw policy implications from these findings for countries exposed to safe haven capital flows, for countries facing long-term appreciation pressures and for countries that specialise in low-technology exports.

The purpose of this research is to build an android based pathfinding adventure game where user gets information about Indonesian culture, especially the traditional houses including the folk songs and the traditional weapons in certain areas. The method used is by questionnaires, interviews, observation, and literature study. This application also implements the A* algorithm to solve the pathfinding problems. The result of this research is "The Adventure of BipBop" app that can make the user can feel the experience of playing that is not only entertaining but also as a medium to convey about the culture of Indonesia and help preserve the traditional house of Indonesia. Most of the respondents find out that the application can provide Indonesian culture well (91.7%). Furthermore, this application can realize about 84.5% of players to help preserve the traditional culture in Indonesia.

“…Because presbyopia is diagnosed in middle-aged or older individuals, its incidence has risen in parallel with the increase in mean population age during the last decades. Handheld screen-enabled devices that include smartphones, tablets, and e-readers have had an exponential increase in use during the last 15 years, starting with the launch of the first iteration of the iPhone in 2007, with annual sales of smartphones numerically surpassing those of personal computers since 2011 3 . Although adoption of handheld screen-enabled devices in older adults has been slower, by 2021, 83% of adults aged 50 to 64 years and 61% of those 65 years or older owned a smartphone, whereas approximately 53% of adults also own a tablet device 4…”

Correction of Presbyopia Alone Does Not Adequately Protect against Digital Eye Strain from Handheld Devices

SIGNIFICANCE:The use of screen-enabled handheld devices has increased exponentially during the last few years among the older adults. Up until now, a general suggestion for preventing symptoms of digital eye strain with large screen use was to address any existing refractive error, including presbyopia. It is unclear whether this advice is of consequence in the case of smaller handheld devices. PURPOSE:The aim of this study was to examine whether correcting presbyopia ameliorates the negative effect on digital screen use, examining handheld devices where these issues are expected to be more acute with presbyopic individuals.METHODS: This is a cross-sectional study of 120 consecutive participants who had received correction for presbyopia during the past month and returned for a routine follow-up examination. The participants filled in a demographics questionnaire, questions on time spent online and using devices with digital screens, data on their eye complaints, and the validated Digital Eye Strain Questionnaire (DESQ). RESULTS:The DESQ factor scores and total score correlated with the near addition (P < .001). Higher DESQ scores were associated (by order of magnitude) with higher near addition and a lower amount of time spent using a handheld screen-enabled device (P < .001) while controlling for age and type of corrective lenses. CONCLUSIONS:Results indicate that older adults are at an additional disadvantage while using handheld screen-enabled devices compared with younger adults: they are more likely to be presbyopes and need higher near addition, yet increasing near addition does not guarantee greater comfort in the use of smartphones but rather increase the likelihood of experiencing digital eye strain symptoms.
