Many established firms make use of zigbee modules and heavy processors which in turn adds up to the cost. Installation of this system is also complicated and requires changing the complete cabling and panels. As a result, this technology is far away from mass implementation and is available to a few percent of population worldwide i.e. 7.7%. The approximate cost of installing one automated switch is 3000 Indian Rupee. In this paper we aim to substantially reduce the cost of home automation without compromising the product quality by deploying our module by using Wi-Fi with our circuit and adapting our module to current cabling system present in respective homes. The module will possess an advantage of detecting the switching status of mechanical switches present along with it. Using Wi-Fi module will have numerous advantages over other protocols as Wi-Fi is compatible with smart phones, routers and PCs. It will not require any additional components for internet connectivity. Internet connectivity will mean that the user will be able to control the appliances worldwide. Our module will use MQTT (Message Queuing Telemetry Transport) for robust pub-sub architecture. The user will be able to control appliances with application installed on user’s smart phone or PC. We’ll be able to monitor all the switching of appliances without any load on our module. All the major processing is shifted on the server side which will in turn keep our module fast.

The study was undertaken to determine the incidence of the reactions as to correct their cause and prevent recurrences. Materials and Methods: It was a retrospective review of all transfusion-related adverse events reported within 2014–2015. They were analyzed as per the protocol laid down by the department. Results: A total of 31,074 units of blood components were issued during the study period and 28 patients developed transfusion reactions. Maximum cases were due to allergic reaction (n = 15, 53.57%) and were mostly females. Packed red blood cells were also the most common component associated with the transfusion reactions. Conclusion: Allergic reaction was the most common acute transfusion reaction followed by febrile nonhemolytic transfusion reaction. Sensitization of all the health personnel involved in the transfusion chain and strict hemovigilance program enforcement will help in improving the safety of blood transfusion.

The developed system has features like controlling the appliances and intrusion detection. Controlling can be done through the App as well as manually. The system also helps in monitoring humidity and room temperature. The home automation becomes important because it gives the user the comfort and ease for using the home appliances. The implementation and design of wireless home automation control uses MQTT protocol technology. The mobile application via Wi-Fi is used to control the selective home appliances with integral security and protection. The device (Wi-Fi module) ESP8266 Node MCU has been used with a relay module and a dimmer circuit module, which consists of optocoupler, triac and a voltage regulator to control the voltage of the incandescent bulb and the fan, whereas the florescent light is connected with the relay module. The IR sensor is a motion sensor used for detecting intrusion and get...

However, firms of higher productivity also have less volatile markups, i.e, they adjust their markups less frequently than do firms of lower productivity. Such heterogeneous and complex firm behavior may be the reason why we are unable to explain the lack of response of aggregate prices to exchange rate movements. JEL Classification: F14, F41

Using monthly data on tariffs and employment, I find that in the period of January 2017 to March 2019, commuting zones more exposed to Chinese retaliatory tariffs experienced a decline in employment growth, whereas U.S. import tariffs had no immediate effect on employment growth. I also study the employment effects of a hypothetical trade war between the United States and China by calculating counterfactual employment changes under three different retaliation scenarios and find that had the U.S. imposed tariffs in the 1991-2007 period on all products, the large job-destroying effect of the ‘China shock’ would not have occurred, irrespective of the retaliation strategy pursued by China. However in the post-recession period of 2010-2016, the ‘China shock’ no longer exists and therefore U.S. import tariffs would not have had a job-creating effect. This ...

This paper estimates the effects of import exposure from China on employment in U.S. occupations from 2002 to 2014. After obtaining occupation-specific measures of Chinese import exposure and sorting occupations in tertiles from low to high wage, from routine to non-routine, and from low to high education, we find that Chinese import competition reduces employment in lower-indexed occupations under each sorting criteria. The employment reduction in the lowest tertile of occupations occurs in Chinese-trade exposed and unexposed sectors, which suggests the existence of local labor market effects in the presence of a strong regional concentration of lower-indexed occupations.

The first chapter provides evidence on the short-run and long-run distributional effects of tariff shocks on employment in the United States. Using monthly data on tariffs and employment, I find that in the period of January 2017 to March 2019, commuting zones more exposed to Chinese retaliatory tariffs experienced a decline in employment growth, whereas U.S. import tariffs had no immediate effect on employment growth. I also study the employment effects of a hypothetical trade war between the United States and China by calculating counterfactual employment changes under three different retaliation scenarios and find that had the U.S. imposed tariffs in the 1991-2007 period on all products, the large job-destroying effect...
