Brain-to-brain interface technology: A brief history, current state, and future goals.

A brain-to-brain interface (BBI), defined as a combination of neuroimaging and neurostimulation methods to extract and deliver information between brains directly without the need for the peripheral nervous system, is a budding communication technique. A BBI system is made up of two parts known as the brain-computer interface part, which reads a sender's brain activity and digitalizes it, and the computer-brain interface part, which writes the delivered brain activity to a receiving brain. As with other technologies, BBI systems have gone through an evolutionary process since they first appeared. The BBI systems have been employed for numerous purposes, including rehabilitation for post-stroke patients, communicating with patients suffering from amyotrophic lateral sclerosis, locked-in syndrome and speech problems following stroke. Also, it has been proposed that a BBI system could play an important role on future battlefields. This technology was not only employed for communicating between two human brains but also for making a direct communication path among different species through which motor or sensory commands could be sent and received. However, the application of BBI systems has provoked significant challenges to human rights principles due to their ability to access and manipulate human brain information. In this study, we aimed to review the brain-computer interface and computer-brain interface technologies as components of BBI systems, the development of BBI systems, applications of this technology, arising ethical issues and expectations for future use.

Perspectives and expectations of stroke survivors using egocentric cameras for monitoring hand function at home: a mixed methods study

Purpose Most stroke survivors have remaining upper limb impairment six months after stroke and require additional rehabilitation and help from family members to enhance their performance of daily activities. First-person (egocentric) video has been proposed to capture the activities of daily living (ADLs) of stroke survivors in order to assess their hand function at home. This study explored the experiences and expectations of stroke survivors regarding the use of egocentric cameras in daily life for rehabilitation applications. Methods Twenty-one chronic stroke survivors recruited for the study were asked to record three sessions of 1.5 h of video of their ADLs at home over two weeks. Their experiences and expectations after completing the recordings were discussed using a structured questionnaire and a semi-structured interview. The questionnaire and interview data were analysed using descriptive statistics and content analysis, respectively. The results were further integrated using a mixed methods analysis for mutual explanation and elaboration. Results The themes generated were Camera Usability, Privacy Concerns Related to Home Recordings, Future Use of the Camera in Public, and Information Usefulness. The participants perceived that the camera was easy to use, the information obtained from the recordings was beneficial, and no major concerns about recording at home. A discreet camera and a solution to privacy issues were prerequisites to recording tasks in public. Conclusions There was high acceptance among stroke survivors regarding the use of wearable cameras for rehabilitation purposes in the future. Concerns to be managed include discomfort, self-consciousness, and the privacy of others. Implications for rehabilitation The egocentric camera was easy for the stroke survivors to use at home. However, they expressed a preference for cameras to be less noticeable and lighter in the future to minimize self-consciousness and discomfort. Expectations for future use of an egocentric camera for upper limb rehabilitation at home from the perspectives of stroke survivors included receiving feedback on their hand function in daily life and guidance on how to improve function. Privacy concerns of stroke survivors regarding recording activities of daily living were mostly avoidable by planning in advance. However, some personal hygiene tasks and virtual meetings were recorded by accident. A checklist of common activities that may raise privacy issues can be provided along with the camera to serve as a reminder to avoid these issues.

Young adults’ intention to quit using JUUL

BackgroundWith research indicating some young audiences may desire to quit using JUUL, a high-nicotine e-cigarette, we sought to explore factors that may motivate them to quit. MethodsThis sequential, mixed methods study included a cross-sectional online survey of college students (n = 631) followed by in-person interviews (n = 51) with survey participants. Data were collected March-April 2019. The survey asked about intention to quit using JUUL. A latent class analysis (LCA) identified participant groups who would quit for various reasons. Participants were also asked ‘Can you be too old to JUUL?’ during the survey. During the interviews, participants were provided preliminary survey findings and asked about their perceptions of the data. Interview participants were also asked about their expectations for future use of JUUL. ResultsFour classes emerged from the LCA, indicating costs to self (i.e., harm to lungs/brain, price; 46.8%), financial costs (36.6%), all costs (e.g., social, monetary, health; 9.3%), and harm to self (7.3%) may have influenced our sample’s decision to quit using JUUL. Interviewees affirmed desires to quit using JUUL, especially after leaving college. Only 27.19% of survey participants reported an age threshold for using JUUL (M = 31.8 years, SD = 10.0); however, several interviewees explained that although someone could not be too old to JUUL, it would be ‘immature’ or ‘childish’ for adults who were not trying to quit smoking to use JUUL socially. DiscussionComprehensive tobacco control strategies such as taxing e-cigarettes, marketing campaigns, and nicotine cessation programs are needed to help nicotine dependent young adults quit using high-nicotine e-cigarettes.

Association Between School-Level Prevalence of Electronic Cigarette Use and Student-Level Use Behaviors, Pre-Use Intentions, and Risk Perceptions: Evidence From the 2014 US National Youth Tobacco Survey.

Adolescent electronic cigarette ("e-cigarette") use tripled in recent years, yet little is known about the school-level correlates of teenage e-cigarette use, harm and risk perceptions, or pre-use intentions to use. Multilevel regression and 2014 National Youth Tobacco Survey data were used to assess school-level e-cigarette prevalence and person-level e-cigarette use as well as age at initiation and frequency of use (among initiates), expectations for future use (among abstainers), and perceived e-cigarette addictivity and harm. Lifetime use was higher among students in medium- (odds ratio [OR] = 2.30, 95% confidence interval [CI] = 1.82, 2.89) and high- (OR = 4.66, 95% CI = 3.67, 5.90) versus low-use schools. Past 30-day use followed a similar pattern. Multilevel ordinal logistic models revealed that initiates from high-use schools reported more days of use in the past month (OR = 2.25, 95% CI = 1.52, 3.33) and higher age-at-first-use (OR = 1.45, 95% CI = 1.08, 2.00) than students at low-use schools. Expectations for future use were higher among abstainers from medium- and high- versus low-use schools, and among all students, perceived addictivity and harm caused by e-cigarettes were lower in medium- and high- versus low-use schools. School context is associated with multiple dimensions of e-cigarette use, pre-use intentions, and perceptions of e-cigarette health risks. The current study demonstrates a link between school prevalence of e-cigarette use and student-level use, as well as perceived risks of e-cigarette use, age of initiation and frequency of use among users, and intentions to use among abstainers. Health communication and prevention initiatives should target school social environments to promote nicotine abstinence and a culture of health.

Perceived risk of methamphetamine among Chinese methamphetamine users

BackgroundMethamphetamine use has grown considerably in China in recent years. Information about perceptions of risk on methamphetamine is important to facilitate health promotion efforts. MethodsUsing both survey data and qualitative interview data, the authors evaluate the perceived risk of methamphetamine use among Chinese users using a mixed-methods approach. Through Respondent Driven Sampling, the authors recruited a sample of 303 methamphetamine users in Changsha, China. ResultsA majority (59.1%) perceive that infrequent methamphetamine use poses no risk to the user, while 11.2% perceive at least moderate risk for light use. A majority (56.7%) perceived at least moderate risk associated with regular methamphetamine use. Most (82.2%) also perceive methamphetamine to be easily obtainable. A path model indicates that perceived risk shapes intentions to use and expectations of future use, as does perceived availability. Qualitatively, while addiction was the most common risk discussed by users, they differed on whether they perceived the drug addictive. Other concerns raised by interviewees included impaired cognition, mental health problems, physical harm, and social dysfunction. ConclusionWhile some users identify significant risks with methamphetamine, others do not perceive its use to be problematic. Collectively, these findings indicate that intervening upon perceptions of risk among Chinese methamphetamine users may be a means to influence intentions to use.

Evaluating a Concept for an Animal Welfare Assessment System Providing Decision Support Using Qualitative Interviews

AbstractQualitative interviews of farmers were carried out as part of a project focusing on developing animal welfare assessment systems (AWASs) in dairy, pig and mink production systems (26 farms in total). The aims of the interviews were to investigate farmers’ perceptions and experience of how an AWAS worked, and to explore their expectations for future use of AWASs. All interviews were taped, transcribed and analysed using a grounded-theory approach. The importance of different elements of the AWAS differed between farmers, and between farmers and the AWAS project implementation group. More direct associations between welfare assessment and production results (and other ‘common measures ‘) were requested by farmers. The whole AWAS ‘package’ was viewed as being too complex and expensive for most farmers, particularly as it involved multiple assessments over time. A range of themes emerged from the analysis. One of these, here referred to as ‘us and them’, is explored and discussed in this paper. Farmers were concerned that the AWAS could be used negatively in relation to consumers and political decisions, and they underlined that if the AWAS was to be used as a decision support tool (ie a system to assist them in making decisions about improvements in their herds and to guide their initiatives and improvements), it should include dialogue and details of local farm conditions. Qualitative interviews were found to provide valuable insight into farmers’ perceptions and expectations of animal welfare assessment methods.

Social Influences on Individual Drug USE: Three Distinct Sub-Cultures Among Agency Non-Attenders

This study was concerned with the similarities and differences between different groups of drug users. It examines social norms in each group, including group attitudes and concurrent drug use behaviour and considers changes over time. In-depth semi-structured interviews were carried out within each of seven distinct social groups of drug misusers. identified by using the snowballing method. Within the sample as a whole, extent of drug experience and severity of drug dependence were inversely correlated with age of first drug use. and positively correlated with a number of measures of poor self-care and antisocial behaviour. The qualitative data were examined for themes to distinguish between groups of drug users. The major themes to emerge were: drug misuse behaviours and patterns of misuse: social relationships: attitudes to drug misuse; and attitudes to risks and problems. Three homogeneous groups were identified from similarities and differences in these themes: young experimental users, moderate social users, and heavy chaotic users. These groups differed in their drug experience and in their expectations of future use. The similarities in drug use behaviour within groups and differences between groups indicate that social group membership may well influence individual attitudes and behaviour. The significance of these findings for policy and practice are considered.

Do Drug Prevention Effects Persist into High-School? How Project ALERT Did with Ninth Graders

Background. This article reports follow-up results during grade 9 for a multisite drug prevention program that curbed both marijuana and cigarette use during junior high. Based on the social influence model of prevention, the curriculum sought to motivate young people against drug use and to teach them skills for resisting pro-drug pressures. Methods. Thirty schools drawn from eight urban, rural, and suburban communities in California and Oregon were randomly assigned to three experimental conditions, two treatment groups and one control. Students in 20 schools received 11 lessons, 8 during grade 7 and 3 in grade 8; in 10 of the treatment schools, older teens assisted an adult teacher in program delivery. Students were pretested prior to the program (grade 7) and post-tested 24 months later (grade 9). Results. Earlier effects on cognitive risk factors (perceived consequences of drug use, normative beliefs, resistance self-efficacy, and expectations of future use) persisted through grade 9 in the teen leader schools; in the condition under which adults taught the lessons without teens, the prior beneficial effects on beliefs largely eroded. All of the earlier effects on actual use disappeared by grade 9, regardless of who taught the lessons. Conclusion. Continued reinforcement of earlier lessons may be required to sustain prevention gains through the transition to high school.

Changing adolescent propensities to use drugs: results from Project ALERT.

Do successful drug prevention programs suppress the risk factors they were intended to modify? This paper addresses that issue for Project ALERT, a school-based program for seventh and eighth graders that has been shown to curb both cigarette and marijuana use. Evaluated with over 4,000 students in an experimental test that included 30 diverse California and Oregon schools, the curriculum seeks to help young people develop both the motivation to avoid drugs and the skills they need to resist pro-drug pressures. Using regression analyses, we examine the program's impact on the intervening (cognitive) variables hypothesized to affect actual use: adolescent beliefs in their ability to resist, perceived consequences of use, normative perceptions about peer use and tolerance of drugs, and expectations of future use. The analysis depicts program effects for perceptions linked to each target substance (alcohol, cigarettes, and marijuana), across all students and for those at different levels of risk for future use. Results show that the curriculum successfully dampened cognitive risk factors from each of the above categories for both cigarettes and marijuana, indicating that social influence programs can mitigate a broad range of beliefs associated with the propensity to use drugs. However, it had a limited impact on beliefs about alcohol, the most widely used and socially accepted of the three drugs. Implications for drug prevention programs and practitioners are discussed.

Empirical effects of selected antecedent computer literacy skills on computer orientation of college students

Empirical evidence is presented regarding the relationship between certain basic computer related skills and perceptual orientations regarding understanding and applications. Specifically, typing and/or word processing skills were associated with a significantly greater degree of conceptual understanding of computer use as measured by self-report scales. With regard to the application dimension, only subjects indicating word processing skills were found to report significantly higher expectations of future use. Caution in generalizing these findings is urged due to the scope of the sample, college business majors, and the unidimensional dependent measures.
