Copyright on the WWW: Linking and Liability

The World Wide Web (WWW) is so often used as a way of interacting with the Internet that many people mistakenly confuse the two, referring to the Internet as the Web and vice versa. Of course, the Internet and its native applications predate the development of the WWW protocols by decades. Still, given the overwhelming amount of available Internet bandwidth now devoted to the transmission of web pages, there is no doubt that the WWW is the interface of choice for most users of the world\u27s most pervasive computer network. The WWW is not the Internet, but there can be no doubt that it is the Internet\u27s first killer app

Declines in prevalence of adolescent substance use disorders and delinquent behaviors in the USA: A unitary trend?

AbstractBackgroundDownward trends in a number of adolescent risk behaviors including violence, crime, and drug use have been observed in the USA in recent years. It is unknown whether these are separate trends or whether they might relate to a general reduction in propensity to engage in such behaviors. Our objectives were to quantify trends in substance use disorders (SUDs) and delinquent behaviors over the 2003–2014 period and to determine whether they might reflect a single trend in an Externalizing-like trait.MethodsWe analyzed data from 12 to 17 year old participants from the National Survey on Drug Use and Health, a representative survey of the household dwelling population of the USA, across the 2003–2014 period (N = 210 599). Outcomes included past-year prevalence of six categories of substance use disorder and six categories of delinquent behavior.ResultsTrend analysis suggested a net decline of 49% in mean number of SUDs and a 34% decline in delinquent behaviors over the 12-year period. Item Response Theory models were consistent with the interpretation that declines in each set of outcomes could be attributed to changes in mean levels of a latent, Externalizing-like trait.ConclusionsOur findings suggest that declines in SUDs and some delinquent behaviors reflect a single trend related to an Externalizing-like trait. Identifying the factors contributing to this trend may facilitate continued improvement across a spectrum of adolescent risk behaviors.</jats:sec

Integrating Wellness within Group Counseling for Latinx Adolescents

Latinx adolescents may begin middle school with lower levels of life satisfaction and hope. In the current study, we implemented a small-series (N = 4) single-case research design to evaluate the impact of a group counseling wellness experience to increase Latinx adolescents\u27 life satisfaction and hope. Analysis of participants\u27 scores on outcome measures yielded treatment effects indicating that the group counseling wellness experience may be effective for increasing hope and life satisfaction. Implications for school counselors are provided

Exploring the Impact of a Positive Psychology Intervention with Latina/o Adolescents

Latina/o adolescents may begin middle school with lower levels of life satisfaction, hope, and self-compassion. In the current study, a small-series (N = 5) single-case research design was implemented to evaluate the impact of a positive psychology group counseling experience to increase Latina/o adolescents’ life satisfaction, hope, and self-compassion. Analysis of participants’ scores on outcome measures yielded treatment effects indicating that the positive psychology group counseling experience may be effective for increasing hope, life satisfaction, and self-compassion. Given that the positive psychology approach was a promising approach for improving Latina/o adolescents’ positive outcomes, implications for school counselors to integrate positive psychology into treatment processes are presented

Beekeeping in Jalisco, México

The purpose of this study was to analyze the socioeconomic factors that influence the beekeeping process and describe the current situation in beekeeping technology development in the south and southeast regions of Jalisco. The study was conducted by reviewing secondary sources of documentary information and the primary information was obtained by means of a survey, analyzing demographic, social, technological, and economic variables. From January to April 2011, a stratified sampling was conducted of six strata of beekeepers, with a final sampling of 183 beekeepers. We applied a frequency analysis, ANOVA (Waller-Duncan), and contingency tables (χ2). The average age observed for the beekeepers was 47 years, with fewer women participating in the activity, and an above national average level of education. The majority keep their apiaries in rented premises, a high percentage outside the municipality where they live. The honey obtained is multiflora and the main harvest is in the autumn, with a honey yield per hive below the national average. A number of problems affect the production sector including environmental factors, production costs, and varroa. We observed little diversification; in addition to honey only beeswax is recovered, and only a minority keep a record of production costs. There is wide participation in beekeeping associations and in training provided by different public and private bodies. There is a willingness to adopt new technologies and equipment for honey production with good practice standards

Dementia Prevalence and Onchocerca volvulus Infection among Rural Elderly Persons in the Ntui Health District, Cameroon: A Population-Based Study

Recent research suggests that infection with Onchocerca volvulus induces neurocognitive decline. This study sought to compare the cognitive outcomes of elderly persons based on onchocerciasis infection status and report the overall prevalence of dementia in the rural Ntui Health District in Cameroon. A community-based approach was used to recruit 103 participants aged ≥60 years. Dementia screening was done using the Community Screening Interview for Dementia (CSID) tool with a cut-off value of ≤29.5. O. volvulus infection was determined via microscopic examination of skin snips and serological testing of Ov16 antibodies using rapid diagnostic tests. Overall, the prevalence of dementia was 10.7%. Among the tested individuals, 17.9% (15/84) and 62.1% (41/66) were positive for O. volvulus and Ov16 antibodies, respectively. A multivariable linear regression model of CSID scores found a significant positive association with education level (8.654; 95% CI: 2.0870 to 15.222). However, having a positive skin snip for O. volvulus (−3.399; 95% CI: −6.805 to 0.007) and inhaling tobacco (−5.441; 95% CI: −9.137 to −1.744) tended to lower the CSID scores. Ongoing onchocerciasis transmission in the Ntui Health District may constitute a risk factor for dementia. Strengthening onchocerciasis elimination and adopting healthier lifestyles would contribute to dementia prevention among the elderly residing in endemic communities

Mesenchymal Stem Cells and Extracellular Vesicles: An Emerging Alternative to Combat COVID-19

The global SARS-CoV-2 outbreak has been accompanied with severe socio-economic and health burdens that will ripple through history. It is now known that SARS-CoV-2 induces a cytokine storm that leads to acute respiratory distress syndrome and systemic organ damage. With no definitive nor safe therapy for COVID-19 as well as the rise of viral variants the need for an urgent treatment modality is paramount. Mesenchymal stem cells (MSCs) and their extracellular vesicles (EVs) have long been praised for their anti-viral, anti-inflammatory and tissue regenerative capabilities. MSCs and their EVs are now being studied for their possible use as a treatment modality for COVID-19. In this review we explore their capabilities and outline the evidence of their use in ALI, ARDS and COVID-19
