Since the Pew Research Center's Internet & American Life Project first started tracking teen cell phone use, the age at which American teens acquire their first cell phone has consistently grown younger. In Pew Internet's 2004 survey of teens, 18% of 12-year-olds owned a cell phone. In 2009, 58% of 12 year-olds own a cell phone. We also have found that cell phone ownership increases dramatically with age: 83% of teens age 17 now own a cell phone, up from 64% in 2004.
Personal privacy in the networked age is limited by three dimensions of “veillance.” They shape people’s behavior and their anxieties about the future of privacy. Lee Rainie will present the latest survey findings from the Pew Research Center about how people try to navigate this new environment in their relationship with government, commercial enterprises, and each other. He will also discuss how some technologists are trying to respond.

Kristen Purcell was invited to speak this Thursday, August 12th, with the staff of the online news site Philly.com. She will share data on online news and information consumption from Pew Internet’s report Understanding the Participatory News Consumer (link). Kristen will highlight some findings about local news coverage that were not included in the original report. Roughly four in ten adults say there is currently not enough news coverage of their neighborhood or local community (38%) or that there is not enough coverage of their state (39%). These “local news enthusiasts” are slightly younger and more mobile than other adults, and are more engaged in social network site use and in commenting on and sharing news they find online.

Abstract
Cell phones have become a norm in the society today. In fact, many people are likely to be surprised if they meet a person who does not own a cell phone. Therefore, there is a higher chance that more than one in two people possess a cell phone, and this number is increasing as the days go by. The influence that these cell phones have on society has become huge. For instance, they have made several advances through modern technology, which has made it possible for people to be connected with friends and family.
Keywords: cell phones influence.
Introduction
Today, cell phones have become a major part of society. In fact, almost everyone owns a cell phone, and the chances of finding someone making a phone call or texting away on the high-tech devices are very high. Contrary to the belief that cell phones have catastrophic effects on people, this view is actually misleading. In as much as many people think that there is a connection between cell phone usage and some type of cancers, this view remains to be a perception rather than a fact. In addition, society has continued to reap some positive aspects with the use of cell phones since these values far much outweigh the negative issues (Nakaya, 2015). Ultimately, many social disasters have been averted with the use of cell phones. Therefore, this paper aims to show that cell phones are not dangerous as perceived by many people.
Quite a number of people think that cell phones have some adverse effects on their lives, which may not be true. In fact, the statements by the Federal Communications Commission (FCC) and Food and Drug Administration, as well as point to peer-reviewed studies have concluded that cell phone usage is not associated with the increase of brain tumors or the inception of other health-related problems. These agencies and studies contend that no increase in brain tumor rates has been witnessed despite the fact that millions of people the world over are in possession of cell phones. A study, which was conducted on 358,403 Danish Citizens on Oct. 20, 2011-the largest study that has ever been conducted to date -, concluded that there was no association between the long-term usage of phones (10 years+) and tumors of the brain or the central nervous system (cellphones.procon.org/)
Cell phones have also shaped the society in a positive way. People always want to be connected to their family, friends, and colleagues. These little hand-held devices make it possible. With a cell phone, people have a way of communicating constantly. Aside from remote areas that cell phone industry has not reached, people can, from any part of the country, stay in contact with those who are important to them. It is also possible to conduct any business meeting with a client while driving to meet another (Ling, 2014). In fact, communication ...

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Yesterday was National HIV Testing Day and much of what I ’m going to show you today relates to our efforts to connect people with HIV prevention and treatment services
This data is also part of our toolkit. We use this to inform our work and to inform our colleagues…not you in the room…you ’ve likely bought into the idea. But many of our colleagues have not. Use the data.
Legacy of activism and activity….lots of stakeholders involved in the process.

There is so much information on the internet, sometimes it is a challenge to find what services are available without specific direction. 1. Housing and Urban Development ’s (HUD): Housing Opportunities for Persons with AIDS Program 2. Substance Abuse Mental Health Services Administration's (SAMHSA): Center for Mental Health Services 3. Health Resources and Services Administration (HRSA) 4. Center for Disease control and Prevention (CDC) 5. Office of Population Affairs (OPA) On each of these sites you can find a Health center Ryan White HIV/AIDS program HIV testing and counseling site Agencies that provide care for HIV/AIDS, hepatitis, STIs, tuberculosis Mental health services Substance abuse services Housing opportunities for persons with AIDS Family planning provider
Some are many layers deep in the agency ’s hierarchy Finding agency websites is hard Not recognizable URLs
10 months All of this information and resources pre-existed. AIDS.gov facilitated a conversation between the five agencies. Presented to the Federal HIV/AIDS Web Council in April 2009 Representatives of each of these agencies 1. Built relationships with the various agencies - brought everyone together at the beginning. Identified who at each agency was best able to provide the technical feedback and assistance we needed. (challenge) 2. Communicated directly with the technical teams, either in-agency or contractors, became essential to the success of the Locator. Once they knew the technical specifics - better communicate programmatic issues: budget and staff time Maintaining the relationships with both program folks and technical has been key - corrections or other inquiries from individuals using the Locator. 3. Technical magic Format data
Launched in February 2010
Through the locator, we ’re able to reach each owner of data to correct and update HUD, CDC, SAMHSA, HRSA, OPA Responsive government Positive response Blog post about the experience Build trust for AIDS.gov project
The original concept was to have the locator on the AIDS.gov website. Increased availability Widgets extended the reach beyond the AIDS.gov website and beyond the HIV/AIDS community. Widgets - small application that you can embed in a social network, blog, or website.
Received around 28,000 visits/searches since it first launched Widget – how many people loaded a page with the widget National HIV Testing Day – 1,000 searches we created a special look for the locator widgets Asked partners to place the widget on their web sites. loaded ~1.6 million times (Meaningless: of those 1.6 million loads 2000 real searches) Doesn ’t even mean eyeballs (below the fold) Measured by interactions on the widget and Google analytics on locator.aids.gov
Studies in Austrailia, Kenya, Virgina, Boston, etc.. The SMS reminder programme started in late 2008 at a large Australian sexual health clinic. SMS reminders were recommended 3–6 monthly for MSM considered high-risk based on self-reported sexual behaviour. The evaluation compared HIV negative MSM who had a HIV/STI test between 1 January and 31 August 2010 and received a SMS reminder (SMS group) with those tested in the same time period (comparison group) and pre-SMS period (pre-SMS group, 1 January 2008 and 31 August 2008) who did not receive the SMS. HIV/STI re-testing rates were measured within 9 months for each group. Baseline characteristics were compared between study groups and multivariate logistic regression used to assess the association between SMS and re-testing and control for any imbalances in the study groups. Results There were 714 HIV negative MSM in the SMS group, 1084 in the comparison group and 1753 in the pre-SMS group. In the SMS group, 64% were re-tested within 9 months compared to 30% in the comparison group (p<0.001) and 31% in the pre-SMS group (p<0.001). After adjusting for baseline differences, re-testing was 4.4 times more likely (95% CI 3.5 to 5.5) in the SMS group than the comparison group and 3.1 times more likely (95% CI 2.5 to 3.8) than the pre-SMS group. Conclusion SMS reminders increased HIV/STI re-testing among HIV negative MSM. SMS offers a cheap, efficient system to increase HIV/STI re-testing in a busy clinical setting.
