This study draws on a unique data set of 923 Swiss internet users who had their internet use tracked for at least 30 days on mobile and desktop devices and took part in a survey covering internet usage as well as person-level background variables. The analysis focuses on active usage time overall and on the major services Google Search, YouTube, WhatsApp, Instagram, Facebook, and the online newspaper 20 Minuten. The results showed that overall internet usage time was lower for older and higher-educated users based on both the tracking and survey data, and the reported usage time was consistently higher than the tracked usage time. The tracking data further revealed that internet users in all social groups spent the majority of their time online on a mobile device. The number of users of the major services varied mainly between age groups. These differences were less pronounced when it came to the time users spent engaging with these services. Over the course of a day, the major services varied in their frequency of use: for example, messaging peaked before noon and in the late afternoon, whereas online news use was comparably constant at a lower level.","PeriodicalId":361748,"journal":{"name":"Communication & Technology eJournal","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133028777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Partnering with a major telecommunication company, we field communication programs that provide either a “lump-sum mobile phone calling credit” or “monthly tranches of mobile phone calling credit” to a nationally representative set of low-income adults in Ghana during the crises. Individuals' inability to make unexpected calls, unexpected need to borrow SOS airtime, and to seek digital loans decreased dramatically relative to a control group. As a result, the programs led to a significant decrease in mental distress (-9.8%) and the likelihood of severe mental distress by -2.7 percentage points (quarter the mean prevalence), with null impact on consumption expenditure. Monthly mobile credits are more likely than lump-sum mobile credits to “sustain” larger impacts, suggesting that individuals may face time inconsistency and /or social pressure problems. We emphasize the value of communication and need for many installments of communication transfers during pandemics.","PeriodicalId":361748,"journal":{"name":"Communication & Technology eJournal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124904726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In all investigation, a photograph was always perceived as ‘proof of occurrence of an event’, due to a strong observation that, ‘seeing is believing ‘. Hence, images were considered as a ‘piece of truth’. Normally, an image is authentic if it is an originally recorded or captured from an actual scene or situation using any image capturing device. The captured image is expected to convey the original situation or scene at the source while capturing it in a real sense. In recent decades, due to the accessibility of modern photograph content altering software tools, it is very easy to transform the content of the image and therefore authenticity and integrity of the image is meager and tampering in digital images therefore does not require any specialist skills. This paper presents the modern methodological assessment and analysis of recent image forgery detection techniques. The various methods used in each stage of forgery detection techniques are also briefed. For an immediate reference, the tables of comparison are provided. The subject review paper is intended to help researchers to deliver useful understandings and modernized info about ongoing progress in forgery detection.","PeriodicalId":361748,"journal":{"name":"Communication & Technology eJournal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123760556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The investment levels of the region lag behind those of advanced economies and are impeding substantial progress on digital transformation. Using a database built for this analysis, which covers nearly 90% of Latin American countries for 2007-2017, we confirm the relevance of regulatory and institutional frameworks to explain investment trends in the sector. We also show that a “good” institutional quality contributes significantly to counteract partially a “bad” regulatory environment, and vice versa. Moreover, their impact is significantly stronger when good regulation and institutions interact, suggesting that joint reforms to improve institutions and the regulatory environment would pay off. In particular, improving cybersecurity and piracy control regulation, and fighting corruption and undue influence stand out as the priorities to increase telecommunication investment in Latin America.","PeriodicalId":361748,"journal":{"name":"Communication & Technology eJournal","volume":"133 S226","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132905571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surface Web includes all the websites that are indexed and available to the general public whereas the webpages which are not indexed come under the category of deep web. However, the gravest part of the Deep web is the Dark web. The Dark web is the concealed content of the World Wide Web. It requires specialized software, authentication and some configuration to access. TOR (The Onion Router) is a multilayer encryption technique which provides secrecy and privacy to the user. Many researches and surveys investigated that a majority of internet users consider Deep Web and Dark Web as the same thing. In order to demystify the same and provide a structural analysis of the Internet, this paper sheds light on the current composition of the Internet and the portion of the World Wide Web held by surface web, deep web and the dark web. It also discusses how the dark web is different from the deep web, mechanism of accessing the deep web, tor browser and the benefits of the dark web along with some of the real-life applications.","PeriodicalId":361748,"journal":{"name":"Communication & Technology eJournal","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127299444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inevitable gap between the potential and the extent to which Information Communication Technology is meeting crop marketing in the Agriculture Sector has continued to prompt further research into how the benefits of Information Communication Technology can be better allied. The study used both primary and secondary data to establish the problems and prospects of Information Communication Technology on crop marketing in the Agriculture Sector. The total population for the three districts analyzed comprising six camps under study was 7840; and the sample was 290. The findings revealed that some benefits to be gained by farmers, traders and agricultural workers using Information Communication Technology in crop marketing were that of interactivity which created opportunities and awareness on the availability of crops’ quality, quantity and location. The study concluded that timely knowledge about who was buying the crops, how much one paid and where they were located could be an important tool in decision making by traders, farmers and agricultural extension workers. It enables them to balance their activities. Unfortunately, information on crop marketing rarely reached farmers in rural areas due to poor signals and electricity power outages. It was therefore recommended that establishing market information centers and tele centers in rural areas could boost access to crop marketing information.","PeriodicalId":361748,"journal":{"name":"Communication & Technology eJournal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128366831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
