When Channel Bonding is Beneficial for Opportunistic Spectrum Access Networks

Transmission over multiple frequency bands combined into one logical channel speeds up data transfer for wireless networks. On the other hand, the allocation of multiple channels to a single user decreases the probability of finding a free logical channel for new connections, which may result in a network-wide throughput loss. While this relationship has been studied experimentally, especially in the WLAN configuration, little is known on how to analytically model such phenomena. With the advent of Opportunistic Spectrum Access (OSA) networks, it is even more important to understand the circumstances in which it is beneficial to bond channels occupied by primary users with dynamic duty cycle patterns. In this paper we propose an analytical framework which allows the investigation of the average channel throughput at the medium access control layer for OSA networks with channel bonding enabled. We show that channel bonding is generally beneficial, though the extent of the benefits depend on the features of the OSA network, including OSA network size and the total number of channels available for bonding. In addition, we show that performance benefits can be realized by adaptively changing the number of bonded channels depending on network conditions. Finally, we evaluate channel bonding considering physical layer constraints, i.e. throughput reduction compared to the theoretical throughput of a single virtual channel due to a transmission power limit for any bonding size.Comment: accepted to IEEE Transactions on Wireless Communication

Raising Awareness on LGBTQ+ and Addiction

Often, adults in recovery may have limited understanding of the LGBTQ+ community and how sexual minority status may relate to drug addiction. It becomes a struggle when individuals lack awareness because one may not realize the negative effects it has on those who have struggled or are struggling with coming out which may lead to substance abuse, as well. To address the limited understanding, I created a 3-session curriculum about drug use and some obstacles that members of the LGBTQ+ community face

Work, Stress, and Christian Spiritual Coping

Stress is a common theme in today\u27s work environment. Stress can positively and negatively impact an individual\u27s ability to do work. It has been found that perceived stress at work can impact a person\u27s physical, emotional, and mental state. Studies show a correlation between stress with anxiety, depression, work efficiency, and burnout syndrome. Christian spiritual/ religious coping is one of the significant ways people cope when faced with stress. Spirituality is the belief in a Supreme Being, and Christianity is based on the belief in Jesus Christ as God and the director of humankind. Christian-based spiritual coping with work stress is influenced by the perception of work as a vocation and a direct command from God. Studies have shown that stress and spirituality have an inverse relationship, and thus one\u27s faith can be used as a predictor of how one is likely to react in a stressful work environment. While many studies have been carried out to explore the relationship between spirituality, religiosity, and coping, there is little research on how Christians apply their faith in the work environment. In this qualitative phenomenological study, the lived experiences with workplace stress and spiritual coping was examined in 12 Christian participants. Participants revealed that their faith plays a significant role in coping with workplace stress. Themes that emerged from the data were factors related to workplace stress, as well as psychological, behavioral, and spiritual strategies used to cope with stress. The faith practices that were most reported as helping participants cope with workplace stress were, Bible reading, church attendance, and inner-life connection. This research provides a better understanding of the lived experience of spiritual and religious coping with workplace stress among Christians

The First Amendment and Online Access to Information About Abortion: The Constitutional and Technological Problems with Censorship

To what extent could an abortion-restrictive state impede access to online information about abortion? After Dobbs, this question is no longer theoretical. This essay engages with this issue from both a legal and technological perspective, analyzing First Amendment jurisprudence as well as the technological implications of state-level online censorship. It concludes that the weight of Supreme Court precedent indicates that state attempts to censor information regarding out-of-state abortion services would violate the First Amendment. That said, the essay also recognizes that as Dobbs itself upended precedent, it is unclear what Supreme Court would do when ruling on questions regarding the extent of state power to limit access to information in this domain. The essay also considers the technological implications of state efforts to censor online access to information about abortion, concluding that these efforts would be mostly, though not completely, unsuccessful

Media Analysis and Journalistic Applications

Media has been a part of our lives now for a better part of over a century or more. From newspapers, radio, tv, film, music. All of these have impacted our lives since their creation and have influenced our society for better or worse for educational or not so educational purposes. Media in all of its aspects have been around for many years and that has translated to every part of our society. We see a film and we quickly talk about its whether it was good or bad but we analyze it. This goes for everyone from children to teenagers to adults. Teenagers in high school watch a new show or listen to a new song from their favorite artist and the next day they quickly talk about it with their friends the next in school. In this day and age, a “trend” might start regarding anything teens see on tv. Not only tv but we live in the age of social media which has overtaken our lives. Every social media site now lives on our phones and just like that we can quickly access anything we need from news to music to literally anything. This has either been a bad thing or a good thing depending on what the information being received is being used for. It all depends on how that information is being deciphered. But there it is also Educational Media and this takes us back to the late 60’s early 70’s a time of change in our country leaving the 60s behind and entering the 70’s and a small tv show by the name of Sesame Street
