Effects of a Web–Mail Mode on Response Rates and Responses to a Care Experience Survey: Results of a Randomized Experiment

Abstract Patient experience surveys are vital to evaluating healthcare provider performance. However, declining response rates over time and questions about whether responses reflect the perspectives of all patients under care have raised concerns. One proposed approach to address these concerns is web-based survey administration, a mode that has not been studied in the hospice setting. We tested a sequential web–mail mode for administering a care experience survey in this unique setting, where family caregivers respond after the patient dies. Sampled caregivers of 15,515 patients who died March–August 2021 while receiving care from 56 hospices across the US were randomized to one of four survey modes: mail-only, telephone-only, mail–telephone (mail with telephone follow-up), or web–mail (email invitation to a web survey with mail follow-up). Email addresses were available for 31.3 percent of sampled eligible caregivers. Relative to mail-only (estimated response rate = 35.1 percent), response rates were significantly higher for web–mail (39.7 percent) and mail–telephone (45.3 percent) and significantly lower for telephone-only (31.5 percent). The web–mail response rate was similar to the mail-only response rate among caregivers without email addresses (35.2 versus 34.3 percent), but substantially higher among caregivers with email addresses (49.6 versus 36.7 percent). Web–mail and mail-only respondents reported similar experiences for 26 of 27 evaluative items. Among eligible sampled caregivers, several patient/caregiver characteristics differed by caregivers’ email address availability, but web–mail and mail-only respondents did not differ on any characteristic. A web–mail mode is feasible for surveying bereaved caregivers about care experiences, producing substantially higher response rates than single-mode approaches, with increasing benefits for hospices with higher proportions of caregivers with email addresses. Findings may be applicable to surveys of other sensitive topics and to populations that prefer asynchronous survey modes.

Implementation of Mail Server Based Of Squirrelmail Using Virtualization Technology at Universitas Muhammadiyah Sumatera Utara

Server virtualization technology is the use of one physical machine by several server operating systems. The design and implementation of this mail server was built using Debian.5 as the base operating system server. The design and implementation of mail servers is built using the dns server, web server and mail server / squirrelmail, configured using the help of the virtualbox application as a server. DNS (Domain Name System) is a system that stores information about host names and domain names in the form of scattered databases (distributed databases) on a computer network, for example the Internet. The application used to handle the delivery of mail messages is the mail server. This mail server always receives messages from e-mail clients that the user uses, or maybe from other e-mail servers. Web mail functions to send and view e-mail messages through a web browser. The squirrelmail configuration is done by running the conf.pl: $ / var / www / wemail / config / conf.pl script. Exchange Server services include: Directory Service, Simple Mail Transfer Protocol (SMTP), Post Office Protocol (POP3), IMAP (Internet Message Access Protocol), Complementary Services, System Attendants. For Mail Server Delivery Process can be seen in number5.2.

Development of an international survey attitude scale: measurement equivalence, reliability, and predictive validity

Declining response rates worldwide have stimulated interest in understanding what may be influencing this decline and how it varies across countries and survey populations. In this paper, we describe the development and validation of a short 9-item survey attitude scale that measures three important constructs, thought by many scholars to be related to decisions to participate in surveys, that is, survey enjoyment, survey value, and survey burden. The survey attitude scale is based on a literature review of earlier work by multiple authors. Our overarching goal with this study is to develop and validate a concise and effective measure of how individuals feel about responding to surveys that can be implemented in surveys and panels to understand the willingness to participate in surveys and improve survey effectiveness. The research questions relate to factor structure, measurement equivalence, reliability, and predictive validity of the survey attitude scale.The data came from three probability-based panels: the German GESIS and PPSM panels and the Dutch LISS panel. The survey attitude scale proved to have a replicable three-dimensional factor structure (survey enjoyment, survey value, and survey burden). Partial scalar measurement equivalence was established across three panels that employed two languages (German and Dutch) and three measurement modes (web, telephone, and paper mail). For all three dimensions of the survey attitude scale, the reliability of the corresponding subscales (enjoyment, value, and burden) was satisfactory. Furthermore, the scales correlated with survey response in the expected directions, indicating predictive validity.

The Effect of Utilitarian and Hedonic Value Provided by Web Advertising Mail on Open-market Firm’s Loyalty

본 연구에서는 마케팅과 서비스 분야에서 많이 이용되는 실용적 가치와 쾌락적 가치의 효과가 오픈마켓의 기업의 충성도에 미치는 영향을 분석하였다. 보다 구체적으로, 고객들이 이미 지각하고 있는 오픈마켓 기업의 관계몰입 정도와 연령, 성별을 통제한 상태에서, 오픈마켓 서비스 운영관리자들이 그들의 잠재적인 고객들에게 보낸 웹 메일의 정보에 대해 고객들이 지각한 실용적 가치와 쾌락적 가치가 오픈마켓 기업의 충성도에 미치는 영향을 알아보고자 하였다. 아울러, 관계몰입과 연령 혹은 관계몰입과 성별이 통제된 상태에서, 연령과 성별에 따라 웹 광고메일이 제공한 실용적, 쾌락적 가치가 오픈마켓 기업의 충성도에 미치는 영향력에 대한 조절효과를 파악하고자 하였다. 연구 결과, 관계몰입의 정도와 연령, 성별이 모두 통제되었을 때, 실용적 가치와 쾌락적 가치 모두 오픈마켓 기업의 충성도에 유의한 영향력을 미치는 것으로 나타났다. 마지막으로, 실용적 가치가 오픈마켓의 기업의 충성도에 미치는 영향력에서 연령과 성별에 따른 통계적인 차이는 존재하지 않았지만, 쾌락적 가치는 앞선 관계에서 연령과 성별에 따른 통계적 차이가 있음을 실증적으로 입증되었다.In this study, we mainly examined the effect of utilitarian and hedonic values prevalently used in the marketing and services literatures on the firm’s loyalty in open market. For specific, in control of the level of open market firm’s relational commitment already perceived by customers, age and gender, we intend to examine the effect of web mail information that open market service operators provide their potential users on the firm’s loyalty in open market in terms of utilitarian and hedonic values. In addition, in control of either relational commitment and age or relational commitment and gender, we also investigate the moderating effects of web mail information which provides potential customers with utilitarian and hedonic values on the firm’s loyalty in open market. Our results show that both utilitarian value and hedonic value significantly affect the open market firm’s loyalty under controlling all variables including the relational commitment, age and gender. Lastly, even if there is no statistical difference in the influences of utilitarian value on the firm’s loyalty in terms of age and gender, we empirically validated that the statistical difference is found in the influences of hedonic value on the firms’ loyalty in the same situation.

Straightlining: Overview of Measurement, Comparison of Indicators, and Effects in Mail–Web Mixed-Mode Surveys

Straightlining occurs when survey respondents give identical (or nearly identical) answers to items in a battery of questions using the same response scale, which may reduce data quality. Despite its potential importance, research examining straightlining does not use a standard measurement technique. Further, while mixed-mode studies are increasing in prevalence, few studies compare straightlining behavior in mail versus web surveys. Our article has the following goals: (1) describe and evaluate methods for detecting straightlining and (2) examine effects of education and mode of administration on straightlining in two mail/web mixed-mode surveys. Data for Study 1 are from a 2010 survey of alcohol beliefs and consumption in which 7,200 young adults were sampled from driver’s license records in Wisconsin and randomly assigned to mail–web (mail followed by web) or web–mail (web followed by mail) treatments. Data for Study 2 are from a 2013 survey about a public university and its affiliated health organizations that used an address-based sample and randomly assigned households to one of the three experimental groups: mail-only, web-only, and web–mail. We identify and examine five methods for measuring straightlining: simple nondifferentiation, mean root of pairs, maximum identical rating, standard deviation of battery, and scale point variation. The overall results replicate previously reported findings of a negative association between education and straightlining behaviors except for the standard deviation of battery measure in Study 1. Controlling for gender, race/ethnicity, and education, mode of administration was not significantly related to straightlining for any of the measures, suggesting straightlining behavior is stable across mail and web forms of self-administration.

Characterizing Social Networks and Communication Channels in a Web-Based Peer Support Intervention.

Web and mobile (mHealth) interventions have promise for improving health outcomes, but engagement and attrition may be reducing effect sizes. Because social networks can improve engagement, which is a key mechanism of action, understanding the structure and potential impact of social networks could be key to improving mHealth effects. This study (a) evaluates social network characteristics of four distinct communication channels (discussion board, chat, e-mail, and blog) in a large social networking intervention, (b) predicts membership in online communities, and (c) evaluates whether community membership impacts engagement. Participants were 299 cancer survivors with significant distress using the 12-week health-space.net intervention. Social networking attributes (e.g., density and clustering) were identified separately for each type of network communication (i.e., discussion board, blog, web mail, and chat). Each channel demonstrated high levels of clustering, and being a community member in one communication channel was associated with being in the same community in each of the other channels (φ = 0.56-0.89, ps < 0.05). Predictors of community membership differed across communication channels, suggesting that each channel reached distinct types of users. Finally, membership in a discussion board, chat, or blog community was strongly associated with time spent engaging with coping skills exercises (Ds = 1.08-1.84, ps < 0.001) and total time of intervention (Ds = 1.13-1.80, ps < 0.001). mHealth interventions that offer multiple channels for communication allow participants to expand the number of individuals with whom they are communicating, create opportunities for communicating with different individuals in distinct channels, and likely enhance overall engagement.

Analysis of Cloud Computing Technology

Cloud computing is the good delivery model of cloud service over the internet. In this global world everyone used cloud computing. The technology was economically accepted because of less expensive. Internet is backbone for cloud computing technology. The cloud computing applied in Business, IT sector, social network sites, web mail etc. cloud is a 24X7 nonstop service element. Previous year back if any communication to other people from one place to another place only believes post mail and telephone link. Example, post mail is a late process to send to specific area. But there is a question how much person using letter mail today. In this system is totally changed and peoples are depend upon modern technology. Cloud is a tremendously developing technology in global world Cloud is an extreme benefit and good deployment model. Logically it is outsourced from the third-party, Example Google Drive is a world largest online storage. Till large amount of people nervous while they are using cloud computing, they are concern about the security risk. The paper discusses various risk threat and vulnerabilities located in cloud.

A Comparative Study of Email Forensic Tools

Over the last decades, email has been the major carrier for transporting spam and malicious contents over the network. Email is also the primary source of numerous criminal activities on the Internet. Computer Forensics is a systematic process to retain and analyze saved emails for the purpose of legal proceedings and other civil matters. Email analysis is challenging due to not only various fields that can be forged by hackers or malicious users, but also the flexibility of composing, editing, deleting of emails using offline (e.g., MS Outlook) or online (e.g., Web mail) email applications. Towards this direction, a number of open source forensics tools have been widely used by the practitioners. However, these tools have been developed in an isolated manner rather than a collaborative approach. Given that email forensic tool users need to understand to what extent a tool would be useful for his/her circumstances and conducting forensic analysis accordingly. In this paper, we examine a set of common features to compare and contrast five popular open source email forensic tools. The study finds that all email forensic tools are not similar, offer diverse types of facility. By combining analysis tools, it may be possible to gain detailed information in the area of email forensic.

A Comparison of Virtual Lab Solutions for Online Cyber Security Education

INTRODUCTION Over past decade, there has been a rapid expansion of using practical laboratory exercises to instruct information security courses using online in both academic and commercial settings. WebCT/Blackboard, Desire to Learn, Pearson Learning Studio and proprietary systems such as UMUC's WebTycho, are just some examples of learning management systems (LMS) that have been used in support of online higher education degree programs. The primary advantages of LMS are to facilitate student learning by incorporating a variety of online technologies including web mail, chat rooms, group collaboration and discussion boards along with serving as central repository for course content. However, when it comes to instructing technology-based courses, including information security courses, online educational offerings have something in common with traditional face-to-face instructional methods (e.g., lectures, literature review, reading assignment, etc.) in that while being essential they are not sufficient in themselves. To supplement their online degree programs, several educational institutions have implemented hands-on labs (often called virtual labs) using virtualization (Burd, Seazzu, & Conway, 2009; Fuertes, Lopez de Vergara, & Meneses, 2009; Li, Jones, & Augustus, 2011; Li, Toderick & Lunsford, 2009; Rajendran, Veilumuthu, & Divya, 2010; Tao, Chen, & Lin, 2010; Willems & Meinel, 2008, 2012; Yen, 2010; Zenebe & Anyiwo, 2010). The use of hands on labs, in support of learning outcomes, is strongly supported by educational theory as a productive and effective pedagogical practice. Major theories that support use of this include Tomei's (2001) taxonomy and Gardner's (1993) theory of multiple intelligences. Tomei's taxonomy is a widely accepted educational model that provides framework for proper use of in classroom. The virtual lab touches on many of levels of Tomei's taxonomy and provides students with valuable higher order experiences. In exploration-teaching paradigm, students begin with a directed experience of fundamental principles underlying concepts being taught. This experience is then modified systematically to demonstrate refinements of these principles. Ultimately, students can use ways these refinements are structured to try out additional modifications on their own initiative. Tomei's Taxonomy is a widely accepted educational model that provides framework for proper use of in classroom (Powell et al., 2008). Instructional at this level of taxonomy offers numerous strategies that encourage learning by infusing into curriculum. The application of for integration represents the creation of new technology-based materials, combining otherwise disparate technologies to teach (Tomei, 2001, p. 20). The objective of integration is to develop new, previously non-existent, innovative instructional materials to enhance learning experience. For example, infusion aligns itself well with decision-making and integration levels of Tomei's taxonomy. At decision-making level, students must apply electronic tools for research and problem solving (Tomei, 2001, p. 20). Additionally, virtual lab exercises allow both students and instructors to consider consequences of inappropriate uses of technology and also allows them to assimilate into a personal learning style (Tomei, 2001, p. 20. These instructional activities align with Integration level of Tomei's Taxonomy and further reinforce higher order skills that provide students with an enriching online learning experience. Table 3 in Appendix B illustrates how infusion of virtual labs for two UMUC Cybersecurity courses corresponds to Tomei's taxonomy. …

Virtual Lab for Online Cyber Security Education

INTRODUCTION There has been a rapid expansion of using practical laboratory exercises to instruct information security courses using online technology in both academic and commercial settings. WebCT, Blackboard, and UMUC's internally developed WebTycho, are just some examples of learning management systems (LMS), that have been used in support of online higher education degree programs. The primary advantages of these LMS are to facilitate student learning by incorporating a variety of online technologies including web mail, chat rooms, group collaboration and discussion boards along with serving as central repository for course content. However, when it comes to instructing technology based courses, including information security courses, online educational offerings have something in common with traditional face to face instructional methods (e.g., lectures, literature review, reading assignment, etc.) in that while being essential they are not sufficient in themselves.

The use of hands on labs, in support of learning outcomes, is strongly supported by educational theory as a productive and effective pedagogical practice. Major theories that support the use of this technology include Bloom's Taxonomy and Gardener's theory of Multiple Intelligences. It is a commonly held belief that students learn more efficiently when engaged in higher order thinking. Hands-on lab exercises provide the means to challenge students with these higher order tasks. The use of virtual lab technology is focused in the analysis, synthesis, and evaluation areas of the taxonomy. This is evidenced by the use of the technology in the classroom. As the students are using the virtual lab, they are constantly forced to make very quick connections between what they know and what they are experiencing. In addition, the real-time environment provides an excellent opportunity for the students to make predictions regarding network intrusion and hacker behavior and to test assumptions without damaging an existing network infrastructure. This type of learning and experimenting is an essential element of an effective information security curriculum. In addition, a virtual lab infrastructure can provide a flexible and cost-effective platform that allow for running multiple operating systems and for sharing computing resources. University of Maryland University College (UMUC) founded in 1947, has been offering online courses since 1985. As cyber attacks are being waged all over the world the demand for cyber security professionals has never been greater, UMUC began offering its graduate level online cyber security degree program in Fall 2010 that included launching a computing laboratory based on virtualization technology. The virtual lab requirements included the following objectives: R1. Accessible, secure and seamless access must be provided to the remote virtual lab. This means students will not have to reserve a time to use a virtual resource and that online lab service must be available around the clock, 365 days a year. R2. The remote virtual server must reliably serve a significant number of concurrent users with limited resources. No significant delay should be observed with a large number of concurrent users. R3. The virtual machine (VM) must be configured with the appropriate operating system(s) and include the required security tools for each lab exercise. In order to minimize requirements for students (e.g., configuring or installing software on their own machines), a pool of virtual machines (VM)s and a cloud based network are necessary. R4. Students must have privileged access rights on the virtual machines to execute security or network tools. …

전자메일 서버의 웹 기반 성능 모니터링 시스템 구현

본 논문에서는 대용량 전자메일 서버의 성능 데이터를 수집해 그 분석 결과를 웹 기반으로 관리자에게 제공하는 모니터링 시스템을 구현하였다. 이를 위해 전자메일 서버의 성능 데이터 수집 항목을 도출하고, 각 항목별 측정 임계치를 설정하여 전자메일 서버의 성능을 객관적인 수치로 표현될 수 있도록 하였다. 전자메일 서버의 성능 데이터 수집은 SCOM 2007 서버 모니터링 도구를 이용하였으며, 성능 분석 파라미터 설정은 마이크로소프트사에서 제공하는 Exchange 서버 관리 팩과 SCOM 2007에서 제공하는 모니터링 규칙을 이용하였다. ASP.NET 프레임워크 기반의 C# 프로그래밍을 통해 웹 기반의 성능 모니터링 프로그램을 개발했으며, 성능 분석 결과는 관리자에게 웹 기반의 성능보고서, 장애 보고서 및 가용성 보고서 형태로 제공된다. 장애 요소를 사전에 효율적으로 감지할 수 있어 본 시스템 적용 전후 비교시 60% 이상 장애 건수를 줄일 수 있었으며, 장애 발생시에도 복구에 소요되는 시간을 획기적으로 단축할 수 있었다. In this paper we implemented a web-based performance monitoring system for web mail server. For this system we derived performance monitoring items and fixed its threshold values for each measuring items. We used the SCOM 2007 server monitoring tool for collecting the performance data of web mail server and Exchange server management pack and server monitoring rules of SCOM 2007 to set the performance analysis parameters. We implemented this performance monitoring system using C# programming based on the ASP.NET framework. This system supports web-based performance report, failure report and resource availability report from the performance analysis results. Therefore the manager can easily detect the failures of web mail server in advance and decrease the number of failure over 60%. Also this system helps manager to minimize the recovery time when the failure occurs.

Automatic Email Configuration System Using Multimodal Authentication Interfaces for Smartphones

Email services are among the services most frequently utilized by smartphone users. However, setting up a smartphone email service is very frustrating for ordinary users as the process requires knowledge of complicated email server protocols and types of security. To eliminate the inconvenience, a method in which web mail setting information is preconfigured within an app has been applied to representative smartphone email accounts. However, it is not practical nor realistic to store all web mail setting information in the app; furthermore, private server setting information for schools, working areas and so on, has to be separately established by users. In this paper, we propose a system that removes these inconveniences faced when setting up smartphone email services. The proposed system automatically downloads setting information preconfigured on the email server for users.

Mitigating the Distributed Denial of Service (DDoS) Attacks in Campus Local Area Network(CLAN)

The Campus Local Area Network (CLAN) of academic institutions interconnect computers ranging from one hundred to about twenty five hundred and these computers are located in academic building(s), hostel building(s), faculty quarter(s), students amenities centre, etc all around the campus. The students, faculty and the supporting staff members use the network primarily for internet usage at both personal and professional levels and secondarily for usage of the available services and resources. Various web based services viz: Web Services, Mail Services, DNS, and FTP services are generally made available in the campus LAN. Apart from these services various intranet based services are also made available for the users of the LAN.&#x0D; Campus LAN users from the hostels change very frequently and also sometime become targets (we call as soft targets) to the attackers or zombie because of either inadequate knowledge to protect their own computer/ laptop, which is also a legitimate node of the campus LAN; or their enthusiastic nature of experimentation. The interconnectivity of these legitimates nodes of the campus LAN and that of the attackers in the World Wide Web, make the computers connected in the LAN (nodes) an easy target for malicious users who attempt to exhaust the resources by launching Distributed Denial-of-Service (DDoS) attacks. In this paper we present a technique to mitigate the distributed denial of service attacks in campus wide LAN by limiting the bandwidth of the affected computers (soft targets) of the virtual LAN from a unified threat management (UTM) firewall. The technique is supported with help of bandwidth utilization report of the campus LAN with and without implementation of bandwidth limiting rule; obtained from the UTM network traffic analyzer. The graphical analyzer report on the utilization of the bandwidth with transmitting and receiving bits of the campus LAN after implementation of our bandwidth limiting rule is also given.

E-Library using the Mobile OPAC

In the todays Communication world, mobile and its applications are the most emerging trends. Mobile applications are the exact replacements of web based applications. Based on this statistics we are planning to migrate web based application of college library to mobile application. In most of the college website we see applications like latest news, Attendance, Login and Registrations, EBooks, Forums, Results, Chat application, Web Mail, etc.. Based on the same we would to do the same thing in a mobile application. The reason behind the work is that the mobile applications do not need any third party browsers, or they don't need any domain registration. So in order to take the advantages of all this limitations we are planning to develop the mobile applications. Now the main important modules that I want to implement on my mobile application is OPAC (Online Public Access Catalogue) for a library account. Using OPAC mechanism in mobile one can just access the library account of his/her from anywhere using his mobile device, So that they can check the availability of books in the library instead of going to library. They can even check the number of books that are taken in there account and its submission date, fine to be paid in case.
