Vaccines against drugs of abuse: a viable treatment option?

Science.gov (United States)

Kantak, Kathleen M

2003-01-01

Drug addiction is a chronically relapsing brain disorder. There is an urgent need for new treatment options for this disease because the relapse rate among drug abusers seeking treatment is quite high. During the past decade, many groups have explored the feasibility of using vaccines directed against drugs of abuse as a means of eliminating illicit drug use as well as drug overdose and neurotoxicity. Vaccines work by inducing drug-specific antibodies in the bloodstream that bind to the drug of abuse and prevent its entry into the brain. The majority of work in this area has been conducted with vaccines and antibodies directed against cocaine and nicotine. On the basis of preclinical work, vaccines for cocaine and nicotine are now in clinical trials because they can offer long-term protection with minimal treatment compliance. In addition, vaccines and antibodies for phencyclidine, methamphetamine and heroin abuse are currently under development. An underlying theme in this research is the need for high concentrations of circulating drug-specific antibodies to reduce drug-seeking and drug-taking behaviour when the drug is repeatedly available, especially in high doses. Although vaccines against drugs of abuse may become a viable treatment option, there are several drawbacks that need to be considered. These include: a lack of protection against a structurally dissimilar drug that produces the same effects as the drug of choice;a lack of an effect on drug craving that predisposes an addict to relapse; and tremendous individual variability in antibody formation. Forced or coerced vaccination is not likely to work from a scientific perspective, and also carries serious legal and ethical concerns. All things considered, vaccination against a drug of abuse is likely to work best with individuals who are highly motivated to quit using drugs altogether and as part of a comprehensive treatment programme. As such, the medical treatment of drug abuse will not be radically

CryoSat data over the Greenland Ice Sheet are used to continue elevation height change data over the Greenland ice sheet, following a decade of detailed monitoring of ice sheet changes with GRACE and IceSat. The combination and validation of the different data for measuring changes is quantified...... by using available airborne lidar data from IceBridge and CryoVEx. There is a special challenge of using CryoSat as fill-in between EnviSat and Sentinel-3 for the longterm measurements of surface elevation changes, a key essential climate variable in the ESA Climate Change Initiative. Another challenge...... is the joint utilization of both altimetry and gravity field change measurements for consistent estimates of regional change patterns. In the paper we analyze GRACE, IceSat and CryoSat data since 2003, and present consistent estimates of overall mass changes with average values around -220 GT/year, showing...

Heck, Nicholas C.; Sorensen, James L.

2014-01-01

Little is known about the needs or characteristics of transgender individuals in substance abuse treatment settings. Transgender (n=199) and non-transgender (cisgender, n=13440) individuals were compared on psychosocial factors related to treatment, health risk behaviors, medical and mental health status and utilization, and substance use behaviors within a database that documented individuals entering substance abuse treatment in San Francisco, CA from 2007–2009 using logistic and linear regression analyses (run separately by identified gender). Transgender men (assigned birth sex of female) differed from cisgender men across many psychosocial factors, including having more recent employment, less legal system involvement, greater incidence of living with a substance abuser, and greater family conflict, while transgender women (assigned birth sex of male) were less likely to have minor children than cisgender women. Transgender women reported greater needle use and HIV testing rates were greater among transgender women. Transgender men and women reported higher rates of physical health problems, mental health diagnoses, and psychiatric medications but there were no differences in service utilization. There were no differences in substance use behaviors except that transgender women were more likely to endorse primary methamphetamine use. Transgender individuals evidence unique strengths and challenges that could inform targeted services in substance abuse treatment. PMID:24561017

Friedmann, P D; Lemon, S C; Stein, M D

2001-09-01

To determine whether certain types of transportation assistance improve outpatient treatment retention beyond thresholds shown to have therapeutic benefits, we analyzed data from 1,144 clients in 22 outpatient methadone maintenance (OMM) programs and 2,031 clients in 22 outpatient drug-free (ODF) programs in the Drug Abuse Treatment Outcomes Study (DATOS), a national, 12-month, longitudinal study of drug abuse treatment programs. Directors' surveys provided information about provision of car, van, or contracted transportation services or individual vouchers/payment for public transportation. Chart-abstracted treatment retention was dichotomized at 365 days for OMM and 90 days for ODF. Separate multivariate hierarchical linear models revealed that provision of car, van, or contracted transportation services improved treatment retention beyond these thresholds for both OMM and ODF, but individual vouchers or payment for public transportation did not. Future research should validate whether car, van, or contracted transportation services improve retention and other treatment outcomes in outpatient drug abuse treatment.

2012-12-01

Childhood sexual abuse (CSA) involves multiple complex factors that make the evaluation of therapeutic interventions especially complicated. PTSD prevalence rates of CSA are approximately 37 % -53 %. Several other psychiatric sequelae of CSA exist. CSA appears to disrupt brain and body physiology. One co-located service delivery model reported a 52 % linkage rate of CSA survivors with mental health treatment. This article reviews current literature on the treatment of CSA, including psychosocial interventions, pharmacotherapy, and early preventative interventions. It also provides an update on the short- and long-term sequelae of CSA and implications for future research directions. A literature search of papers published in the last 3 years was conducted using the keywords treatment, sexual abuse, childhood, epigenetics, resilience and review, and searching the following databases: PsycInfo, PubMed, Substance Abuse and Mental Health Services Administration, and Centers for Disease Control.

CubeSat evolution: Analyzing CubeSat capabilities for conducting science missions

Science.gov (United States)

Poghosyan, Armen; Golkar, Alessandro

2017-01-01

Traditionally, the space industry produced large and sophisticated spacecraft handcrafted by large teams of engineers and budgets within the reach of only a few large government-backed institutions. However, over the last decade, the space industry experienced an increased interest towards smaller missions and recent advances in commercial-off-the-shelf (COTS) technology miniaturization spurred the development of small spacecraft missions based on the CubeSat standard. CubeSats were initially envisioned primarily as educational tools or low cost technology demonstration platforms that could be developed and launched within one or two years. Recently, however, more advanced CubeSat missions have been developed and proposed, indicating that CubeSats clearly started to transition from being solely educational and technology demonstration platforms to offer opportunities for low-cost real science missions with potential high value in terms of science return and commercial revenue. Despite the significant progress made in CubeSat research and development over the last decade, some fundamental questions still habitually arise about the CubeSat capabilities, limitations, and ultimately about their scientific and commercial value. The main objective of this review is to evaluate the state of the art CubeSat capabilities with a special focus on advanced scientific missions and a goal of assessing the potential of CubeSat platforms as capable spacecraft. A total of over 1200 launched and proposed missions have been analyzed from various sources including peer-reviewed journal publications, conference proceedings, mission webpages as well as other publicly available satellite databases and about 130 relatively high performance missions were downselected and categorized into six groups based on the primary mission objectives including "Earth Science and Spaceborne Applications", "Deep Space Exploration", "Heliophysics: Space Weather", "Astrophysics", "Spaceborne In Situ

An investigation of scale effects in family substance abuse treatment programs

2010-07-01

Full Text Available Abstract This short report investigates scale effects in family substance abuse treatment programs. In Massachusetts, the family substance abuse treatment programs were much more costly than other adult residential treatment models. State officials were concerned that the "scale" or size of these programs (averaging just eight families was too small to be economical. Although the sample size (just nine programs was too small to permit reliable inference, the data clearly signalled the importance of "scale effects" in these family substance abuse treatment programs. To further investigate scale effects in family substance abuse treatment programs, data from the Center for Substance Abuse Treatment's (CSAT's Residential Women and Children and Pregnant and Postpartum Women (RWC-PPW Demonstration were re-analyzed, focusing on the relationship between cost per family-day and the estimated average family census. This analysis indicates strong economies of scale up until an average family census of about 14, and less apparent scale effects beyond that point. In consideration of these and other study findings, a multidisciplinary interagency team redesigned the Massachusetts' family treatment program model. The new programs are larger than the former family treatment programs, with each new program having capacity to treat 11 to 15 families depending on family makeup.

Illicit drug users sustain the epidemics of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), hepatitis C (HCV), and sexually transmitted infections (STIs). Substance abuse treatment programs present a major intervention point in stemming these epidemics. As a part of the "Infections and Substance Abuse" study, established by the National Drug Abuse Treatment Clinical Trials Network, sponsored by National Institute on Drug Abuse, three surveys were developed; for treatment program administrators, for clinicians, and for state and District of Columbia health and substance abuse department administrators, capturing service availability, government mandates, funding, and other key elements related to the three infection groups. Treatment programs varied in corporate structure, source of revenue, patient census, and medical and non-medical staffing; medical services, counseling services, and staff education targeted HIV/AIDS more often than HCV or STIs. The results from this study have the potential to generate hypotheses for further health services research to inform public policy.

Culturally competent substance abuse treatment with transgender persons.

Nuttbrock, Larry A

2012-01-01

Transgender individuals are misunderstood and inadequately treated in many conventional substance abuse treatment programs. This article reviews current concepts regarding the definition and diversity of transgenderism and summarizes the existing literature on the prevalence and correlates of substance use in transgendered populations. Examples of culturally competent and gender-sensitive treatment in specialized settings are cited, with a call to extend these initiatives throughout the gamut of service venues that engage transgender individuals. Cultural competence combined with gender sensitivity should improve the effectiveness of substance abuse treatment for transgender individuals and will contribute to the goal of providing effective services in an increasingly diverse society.

Soil Aquifer Treatment (SAT) and Constructed Wetlands (CW) Applications for Nutrients and Organic Micropollutants (OMPs) Attenuation Using Primary and Secondary Wastewater Effluents

KAUST Repository

Hamadeh, Ahmed F.

2014-06-01

Constructed wetlands (CW) and soil aquifer treatment (SAT) represent natural wastewater treatment systems (NWTSs). The high costs of conventional wastewater treatment techniques encourage more studies to investigate lower cost treatment methods which make these appropriate for developing and also in developed countries. The main objective of this research was to investigate the removals of nutrients and organic micropollutants (OMPs) through SAT, CW and the CW-SAT hybrid system. CWs are an efficient technology to purify and remove different nutrients as well as OMPs from wastewater. They removed most of the dissolved organic matter (DOC), total nitrogen (TN), ammonium and phosphate. Furthermore, CWs aeration could be used as one of the alternatives to reduce CWs footprint by around 10%. The vegetation in CWs plays an essential role in the treatment especially for nitrogen and phosphate removals, it is responsible for the removal of 15%, 55%, 38%, and 22% for TN, dissolved organic nitrogen (DON), nitrate and phosphate, respectively. CWs achieved a very high removal for some OMPs; they attenuated acetaminophen, caffeine, fluoxetine and trimethoprim (>90%) under different redox conditions. Moreover, it was found that increasing temperature (up to 36 C) could enhance the removals of atenolol, caffeine, DEET and trimethoprim by 17%, 14%, 28% and 45%, respectively. On the other hand, some OMPs, were found to be removed by vegetation such as: acetaminophen, caffeine, fluoxetine, sulfamethoxazole, and trimethoprim. Moreover, atenolol, caffeine, fluoxetine and trimethoprim, showed high removal (>80%) through SAT system. It was also found that, temperature increasing and using primary instead of secondary effluent could enhance the removal of some OMPs. The CWs performance study showed that these systems are adapted to the prevailing extreme arid conditions and the average percent removals are about, 88%, 96%, 98%, 98% and 92%, for COD, BOD and TSS, ammonium and phosphate

It is unclear whether racial differences in treatment effect exist for individuals in substance abuse and domestic violence programs. This study examined racial differences in treatment effect among substance dependent Caucasian and African-American male intimate partner violence (IPV) offenders court mandated to an integrated substance abuse and domestic violence treatment. From baseline to completion of treatment (week 12), 75 participants (39 Caucasian; 36 African-American) were assessed on demographics, substance use, legal characteristics, and use of violence (physical, verbal, and psychological). African-American men served more months incarcerated in their life than Caucasian men. Both groups showed decreases in their use of physical violence and alcohol abuse over treatment. Caucasian men also showed a decrease in their use of verbal abuse. At treatment completion, both groups showed a reduction in physical abuse and alcohol abuse. Caucasian men showed a reduction in their use of verbal abuse, but African-American men did not. Substance dependent African-American male IPV offenders may benefit from interventions that thoroughly target communication skills in addition to issues of substance abuse and IPV to reduce use of verbal abuse and improve treatment outcomes among African American men.

Full Text Available Abstract Background Opiates are the main drugs of abuse, and Methadone Maintenance Treatment (MMT is the most widely administered drug addiction treatment program in Iran. Our study aimed to investigate patterns of pre-treatment drug abuse, addiction treatment history and characteristics of patients in MMT in Tehran. Methods We applied a stratified cluster random sampling technique and conducted a cross-sectional survey utilizing a standard patient characteristic and addiction history form with patients (n = 810 in MMT. The Chi-square test and t-test served for statistical analyses. Results A clear majority of the participants were men (96%, more than 60% of whom were between 25 and 44 years of age, educated (89% had more than elementary education, and employed (>70%. The most commonly reported main drugs of abuse prior to MMT entry were opium (69% and crystalline heroin (24%. The patients’ lifetime drug experience included opium (92%, crystalline heroin (28%, cannabis (16%, amphetamines (15%, and other drugs (33%. Crystalline heroin abusers were younger than opium users, had begun abusing drugs earlier, and reported a shorter history of opiate addiction. Conclusion Opium and crystalline heroin were the main drugs of abuse. A high rate of addiction using more dangerous opiate drugs such as crystalline heroin calls for more preventive efforts, especially among young men.

Full Text Available The causes of drug abuse and criminal behavior are closely linked. Not surprisingly, there is a high percentage of prisoners who during sentence execution abuse or are dependent on drugs. Antisocial personality disorder can be considered a common predictor of committing criminal offenses and drug abuse. A review of studies has revealed a high prevalence of inmates who use drugs while serving a sentence. Also, prison environment represents only a new context of the continuum of drug abuse by inmates. There are different theoretical approaches in explaining this phenomenon. Treatment programs based on empirically validated principles that guarantee the effectiveness, may be one strategy for solving the problem of drug abuse in prisons, with multiple positive effects.

Daughters, Stacey B; Richards, Jessica M; Gorka, Stephanie M; Sinha, Rajita

2009-12-01

Substance abuse treatment programs are often characterized by high rates of premature treatment dropout, which increases the likelihood of relapse to drug use. Negative reinforcement models of addiction emphasize an individual's inability to tolerate stress as a key factor for understanding poor substance use treatment outcomes, and evidence indicates that dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis contributes to an individual's inability to respond adaptively to stress. The aim of the current study was to examine whether HPA axis response to stress is predictive of treatment retention among a sample of drug users in residential substance abuse treatment. Prospective study assessing treatment retention among 102 individuals enrolled in residential substance abuse treatment. Participants completed two computerized stress tasks, and HPA axis response to stress was measured via salivary cortisol at five time points from baseline (pre-stress) to 30 min post-stress exposure. The main outcome measures were treatment dropout (categorical) and total number of days in treatment (continuous). A significantly higher salivary cortisol response to stress was observed in treatment dropouts compared to treatment completers. Further, Cox proportional hazards survival analyses indicated that a higher peak cortisol response to stress was associated with a shorter number of days to treatment dropout. Results indicate that a higher salivary cortisol level in response to stress is associated with an inability to remain in substance abuse treatment. These findings are the first to document a biological marker of stress as a predictor of substance abuse treatment dropout, and support the development and implementation of treatments targeting this vulnerability.

Targeting the treatment of drug abuse with molecular imaging

2007-01-01

Although imaging studies in and of themselves have significant contributions to the study of human behavior, imaging in drug abuse has a much broader agenda. Drugs of abuse bind to molecules in specific parts of the brain in order to produce their effects. Positron emission tomography (PET) provides a unique opportunity to track this process, capturing the kinetics with which an abused compound is transported to its site of action. The specific examples discussed here were chosen to illustrate how PET can be used to map the regional distribution and kinetics of compounds that may or may not have abuse liability. We also discussed some morphological and functional changes associated with drug abuse and different stages of recovery following abstinence. PET measurements of functional changes in the brain have also led to the development of several treatment strategies, one of which is discussed in detail here. Information such as this becomes more than a matter of academic interest. Such knowledge can provide the bases for anticipating which compounds may be abused and which may not. It can also be used to identify biological markers or changes in brain function that are associated with progression from drug use to drug abuse and also to stage the recovery process. This new knowledge can guide legislative initiatives on the optimal duration of mandatory treatment stays, promoting long-lasting abstinence and greatly reducing the societal burden of drug abuse. Imaging can also give some insights into potential pharmacotherapeutic targets to manage the reinforcing effects of addictive compounds, as well as into protective strategies to minimize their toxic consequences

2010-11-01

Full Text Available Abstract Background Despite high levels of substance use disorders in Cape Town, substance abuse treatment utilization is low among people from disadvantaged communities in Cape Town, South Africa. To improve substance abuse treatment utilization, it is important to identify any potential barriers to treatment initiation so that interventions to reduce these barriers can be implemented. To date, substance abuse research has not examined the factors associated with substance abuse treatment utilization within developing countries. Using the Behavioural Model of Health Services Utilization as an analytic framework, this study aimed to redress this gap by examining whether access to substance abuse treatment is equitable and the profile of variables associated with treatment utilization for people from poor communities in Cape Town, South Africa. Methods This study used a case-control design to compare 434 individuals with substance use disorders from disadvantaged communities who had accessed treatment with 555 controls who had not accessed treatment on a range of predisposing, treatment need and enabling/restricting variables thought to be associated with treatment utilization. A hierarchical logistic regression was conducted to assess the unique contribution that the need for treatment, predisposing and enabling/restricting variable blocks made on substance abuse treatment utilization. Results Findings revealed that non-need enabling/restricting variables accounted for almost equal proportions of the variance in service utilization as the need for treatment variables. These enabling/restricting variables also attenuated the influence of the treatment need and predisposing variables domains on chances of treatment utilization. Several enabling/restricting variables emerged as powerful partial predictors of utilization including competing financial priorities, geographic access barriers and awareness of treatment services.

Methadone versus buprenorphine for the treatment of opioid abuse in pregnancy: science and stigma.

Science.gov (United States)

Holbrook, Amber M

2015-01-01

The past decade has seen an increase in rates of opioid abuse during pregnancy. This clinical challenge has been met with debate regarding whether or not illicit and prescription opioid-dependent individuals require different treatment approaches; whether detoxification is preferable to maintenance; and the efficacy of methadone versus buprenorphine as treatment options during pregnancy. The clinical recommendations resulting from these discussions are frequently influenced by the comparative stigma attached to heroin abuse and methadone maintenance versus prescription opioid abuse and maintenance treatment with buprenorphine. While some studies have suggested that a subset of individuals who abuse prescription opioids may have different characteristics than heroin users, there is currently no evidence to suggest that buprenorphine is better suited to treatment of prescription opioid abuse than methadone. Similarly, despite its perennial popularity, there is no evidence to recommend detoxification as an efficacious approach to treatment of opioid dependence during pregnancy. While increased access to treatment is important, particularly in rural areas, there are multiple medical and psychosocial reasons to recommend comprehensive substance abuse treatment for pregnant women suffering from substance use disorders rather than office-based provision of maintenance medication. Both methadone and buprenorphine are important treatment options for opioid abuse during pregnancy. Methadone may still remain the preferred treatment choice for some women who require higher doses for stabilization, have a higher risk of treatment discontinuation, or who have had unsuccessful treatment attempts with buprenorphine. As treatment providers, we should advocate to expand available treatment options for pregnant women in all States.

Abstract Background The rise of authorized marijuana use in the U.S. means that many individuals are using cannabis as they concurrently engage in other forms of treatment, such as substance abuse counseling and psychotherapy. Clinical and legal decisions may be influenced by findings that suggest marijuana use during treatment serves as an obstacle to treatment success, compromises treatment integrity, or increases the prevalence or severity of relapse. In this paper, the author reviews the ...

Metaphyseal fractures mimicking abuse during treatment for clubfoot

Background. Metaphyseal injuries resembling the classic metaphyseal lesion (CML) of abuse may occur as the result of serial casting during treatment of clubfoot deformity. Mentioned in the orthopedic literature in 1972, this iatrogenic fracture has not been described in the radiologic literature nor has the similarity to injuries occurring with abuse been previously recognized. Objective. To describe the mechanism and radiographic appearance of metaphyseal injury observed during serial casting of clubfoot. Note similarities to the CML of abuse. Materials and methods. Eight children ranging in age from 1 to 4 months underwent casting for clubfoot. Five orthopedic surgeons from three different institutions performed the casting. Two patients had spina bifida and one, arthrogryposis. A complete skeletal survey was performed on one child who was abused; there was no suspicion of abuse in the remaining seven. Results. All children manifest injury with periosteal new bone. One child had clear evidence of abuse with 24 rib fractures. X-rays of lower extremities in short leg casts revealed bilateral tibial metaphyseal fractures. Four other children had metaphyseal fractures resembling the CML of abuse, and three developed an area of sclerosis within the metaphysis. Conclusion. In the setting of serial casting for equinovarus deformity, metaphyseal injury even the CML of abuse may be noted. Since inflicted injuries are almost always unobserved and explanations rarely offered, the fact that the CML occurs as a result of orthopedic manipulation may offer some further insight concerning the pathogenesis of this well-described abuse injury.

Correlates of substance abuse treatment completion among disadvantaged communities in Cape Town, South Africa

Directory of Open Access Journals (Sweden)

Pasche Sonja

2010-03-01

Full Text Available Abstract Background Completion of substance abuse treatment is a proximal indicator of positive treatment outcomes. To design interventions to improve outcomes, it is therefore important to unpack the factors contributing to treatment completion. To date, substance abuse research has not examined the factors associated with treatment completion among poor, disadvantaged communities in developing countries. This study aimed to address this gap by exploring client-level factors associated with treatment completion among poor communities in South Africa. Methods Secondary data analysis was conducted on cross-sectional survey data collected from 434 persons residing in poor communities in Cape Town, South Africa who had accessed substance abuse treatment in 2006. Results Multiple regression analyses revealed that therapeutic alliance, treatment perceptions, abstinence-specific social support, and depression were significant partial predictors of treatment completion. Conclusions Findings suggest that treatment completion rates of individuals from poor South African communities can be enhanced by i improving perceptions of substance abuse treatment through introducing quality improvement initiatives into substance abuse services, ii strengthening clients' abstinence-oriented social networks and, iii strengthening the counselor-client therapeutic alliance.

Predictors of substance abuse treatment need and receipt among homeless women.

Tucker, Joan S; Wenzel, Suzanne L; Golinelli, Daniela; Zhou, Annie; Green, Harold D

2011-04-01

Many homeless women do not receive needed treatment for substance abuse. This study identified social network and other predisposing factors associated with perceived need for and receipt of substance abuse treatment among 273 homeless women who screened positive for past-year substance abuse. Perceived treatment need was more likely among women with drug-using sex partners, a denser network, and an arrest history but less likely for those with a minor child and a longer history of homelessness. Receiving treatment was more likely among women who received informational support from their sex partners and who had an arrest history but less likely among those who had a more street-based social network, had a minor child, considered themselves homeless, and recently needed mental health treatment. Treatment services researchers should attend more closely to social contextual factors, as well as the more traditional individual factors, to understand access and barriers to treatment.

Melnick, Gerald; Wexler, Harry K; Chaple, Michael; Cleland, Charles M

2009-03-01

Previous studies demonstrated the relationship between consensus among both staff and clients with client engagement in treatment and between client consensus and 1-year treatment outcomes. The present article explores the correlates of staff consensus, defined as the level of agreement among staff as to the importance of treatment activities in their program, using a national sample of 80 residential substance abuse treatment programs. Constructive conflict resolution had the largest effect on consensus. Low client-to-staff ratios, staff education, and staff experience in substance abuse treatment were also significantly related to consensus. Frequency of training, an expected correlate of consensus, was negatively associated with consensus, whereas frequency of supervision was not a significant correlate. The implications of the findings for future research and program improvement are discussed.

Relationship of trauma exposure and substance abuse to self-reported violence among men and women in substance abuse treatment.

Clark, C Brendan; Reiland, Sarah; Thorne, Chris; Cropsey, Karen L

2014-05-01

Past research showed a relationship between substance abuse and aggression and past trauma and aggression. The nature of the relationships between substance use, trauma, and aggression is inconclusive. The current research hypothesized greater aggression among those with a history of substance abuse and trauma compared with those without such a history and an additive relationship between substance abuse and trauma on aggression. Participants were 615 individuals in a substance abuse treatment program for individuals under criminal justice supervision. Data were collected from face-to-face interviews and self-report measures. Univariate and multivariate analyses assessed the relationships among substance use, trauma, and aggression. Participants with a history of trauma and regular substance use reported the highest rates of homicidal ideation, problem behaviors, and person offenses. Participants in this group also reported greater desire for help managing their stress and tension, dealing with problems in their intimate relationships, developing healthier relationships in general, and learning prosocial approaches to express their feelings. Substance abusing participants who experienced trauma reported more externalizing behaviors and a greater desire for coping- and social-skills training than participants who abused substances but did not report a history of trauma. This suggests that participants in substance abuse treatment programs may have improved outcomes with the addition of components to address these issues.

A rationale and model for addressing tobacco dependence in substance abuse treatment

Directory of Open Access Journals (Sweden)

Richter Kimber P

2006-08-01

Full Text Available Abstract Most persons in drug treatment smoke cigarettes. Until drug treatment facilities systematically treat their patients' tobacco use, millions will flow through the drug treatment system, overcome their primary drug of abuse, but die prematurely from tobacco-related illnesses. This paper reviews the literature on the health benefits of quitting smoking for drug treatment patients, whether smoking causes relapse to other drug or alcohol abuse, the treatment of tobacco dependence, and good and bad times for quitting smoking among drug treatment patients. It also presents a conceptual model and recommendations for treating tobacco in substance abuse treatment, and provides references to internet and paper-copy tools and information for treating tobacco dependence. At present, research on tobacco treatment in drug treatment is in its infancy. Although few drug treatment programs currently offer formal services, many more will likely begin to treat nicotine dependence as external forces and patient demand for these services increases. In the absence of clear guidelines and attention to quality of care, drug treatment programs may adopt smoking cessation services based on cost, convenience, or selection criteria other than efficacy. Because research in this field is relatively new, substance abuse treatment professionals should adhere to the standards of care for the general population, but be prepared to update their practices with emerging interventions that have proven to be effective for patients in drug treatment.

Comparison of drug treatment histories of single and multiple drug abusers in detox.

Science.gov (United States)

Greberman, S B; Jasinski, D

2001-01-01

This study was undertaken to determine differences in previous treatment patterns in individuals currently using different numbers of substances. Medical records of 1198 inpatient detoxification (detox) admissions were analyzed. Numbers of past admissions to completed detox, methadone, or other types of drug abuse treatment were totaled and ranked to determine most frequent type. Within gender, treatment histories of single and multiple drug abusers usually do not differ. The one exception is male multiple drug abusers ages 26-30, who show increased admissions. Possible explanations are that men do not seek treatment before developing medical complications of addiction or until external factors influence admission. There were differences in treatment histories between genders in multiple drug abusers only. Before age 30, women reported increased treatment of certain types. Possible explanations are that treatment priority is given to women who are, or may be, pregnant. Also, younger men may not enter or complete treatment. Previous treatment history may influence many behaviors. The results of this study delineate several valuable indicators for assessing past history.

Study protocol: a randomized controlled trial of a computer-based depression and substance abuse intervention for people attending residential substance abuse treatment

2012-02-01

Full Text Available Abstract Background A large proportion of people attending residential alcohol and other substance abuse treatment have a co-occurring mental illness. Empirical evidence suggests that it is important to treat both the substance abuse problem and co-occurring mental illness concurrently and in an integrated fashion. However, the majority of residential alcohol and other substance abuse services do not address mental illness in a systematic way. It is likely that computer delivered interventions could improve the ability of substance abuse services to address co-occurring mental illness. This protocol describes a study in which we will assess the effectiveness of adding a computer delivered depression and substance abuse intervention for people who are attending residential alcohol and other substance abuse treatment. Methods/Design Participants will be recruited from residential rehabilitation programs operated by the Australian Salvation Army. All participants who satisfy the diagnostic criteria for an alcohol or other substance dependence disorder will be asked to participate in the study. After completion of a baseline assessment, participants will be randomly assigned to either a computer delivered substance abuse and depression intervention (treatment condition or to a computer-delivered typing tutorial (active control condition. All participants will continue to complete The Salvation Army residential program, a predominantly 12-step based treatment facility. Randomisation will be stratified by gender (Male, Female, length of time the participant has been in the program at the commencement of the study (4 weeks or less, 4 weeks or more, and use of anti-depressant medication (currently prescribed medication, not prescribed medication. Participants in both conditions will complete computer sessions twice per week, over a five-week period.

2006-09-01

Full Text Available Abstract Background Despite the importance of identifying co-occurring psychiatric disorders in substance abuse treatment programs, there are few appropriate and validated instruments available to substance abuse treatment staff to conduct brief screen for these conditions. This paper describes the development, implementation and validation of a brief screening instrument for mental health diagnoses and trauma among a diverse sample of Black, Hispanic and White women in substance abuse treatment. With input from clinicians and consumers, we adapted longer existing validated instruments into a 14 question screen covering demographics, mental health symptoms and physical and sexual violence exposure. All women entering treatment (methadone, residential and out-patient at five treatment sites were screened at intake (N = 374. Results Eighty nine percent reported a history of interpersonal violence, and 70% reported a history of sexual assault. Eighty-eight percent reported mental health symptoms in the last 30 days. The screening questions administered to 88 female clients were validated against in-depth psychiatric diagnostic assessments by trained mental health clinicians. We estimated measures of predictive validity, including sensitivity, specificity and predictive values positive and negative. Screening items were examined multiple ways to assess utility. The screen is a useful and valid proxy for PTSD but not for other mental illness. Conclusion Substance abuse treatment programs should incorporate violence exposure questions into clinical use as a matter of policy. More work is needed to develop brief screening tools measures for front-line treatment staff to accurately assess other mental health needs of women entering substance abuse treatment

Risk factors among adolescent substance abusers have been shown to correlate with substance use severity. Characteristics related to severity, such as demographic and family factors, peer influences, psychiatric co-morbidity and HIV risk behaviors, are examined for a sample of adolescent cannabis users entering treatment. These data are from a clinical trial study utilizing blocked random assignment of clients to one of five treatment conditions. The study targeted adolescents entering outpatient treatment for primarily cannabis abuse or dependence. Treatment and research facilities in four metropolitan areas of the US were used to recruit study participants. Treatment was delivered in outpatient drug-free settings. Participants were 600 clients, ages 12-18, admitted to outpatient substance abuse treatment programs for cannabis problems, 96% with DSM-IV diagnoses of substance abuse or dependence, with the remaining 4% having at least one symptom of dependence plus significant problems indicating need for treatment. The Global Appraisal of Individual Needs (GAIN) was used to collect the information presented in this paper. The GAIN incorporates DSM-IV criteria for substance use disorders, conduct disorder and attention deficit hyperactivity disorder, as well as dimensional (scale) measures for physical and mental health. All participants reported at least one symptom of substance use disorders, and 46% met the DSM-IV criteria for substance dependence, while 50% met criteria for a diagnosis of abuse. Only 20% of the participants perceived any need for help with problems associated with their drug or alcohol use. Clients participating in the study typically presented multiple problems at treatment entry, most often including conduct disorder, attention deficit hyperactivity disorder (ADHD), internal (mental) distress, and physical health distress. The co-occurrence of conduct disorder and ADHD was found in 30% of the sample. Clients meeting criteria for substance

Propulsion for CubeSats

Lemmer, Kristina

2017-05-01

At present, very few CubeSats have flown in space featuring propulsion systems. Of those that have, the literature is scattered, published in a variety of formats (conference proceedings, contractor websites, technical notes, and journal articles), and often not available for public release. This paper seeks to collect the relevant publically releasable information in one location. To date, only two missions have featured propulsion systems as part of the technology demonstration. The IMPACT mission from the Aerospace Corporation launched several electrospray thrusters from Massachusetts Institute of Technology, and BricSAT-P from the United States Naval Academy had four micro-Cathode Arc Thrusters from George Washington University. Other than these two missions, propulsion on CubeSats has been used only for attitude control and reaction wheel desaturation via cold gas propulsion systems. As the desired capability of CubeSats increases, and more complex missions are planned, propulsion is required to accomplish the science and engineering objectives. This survey includes propulsion systems that have been designed specifically for the CubeSat platform and systems that fit within CubeSat constraints but were developed for other platforms. Throughout the survey, discussion of flight heritage and results of the mission are included where publicly released information and data have been made available. Major categories of propulsion systems that are in this survey are solar sails, cold gas propulsion, electric propulsion, and chemical propulsion systems. Only systems that have been tested in a laboratory or with some flight history are included.

This paper assesses whether chemically dependent adolescents with comorbid learning disorders (LDs) derived less effective treatment results when compared to chemically dependent adolescents without LD and examines the moderating effects of prior treatments, treatment length, and treatment completion. Two hundred one adolescents were recruited between 1992 and 1993 from Massachusetts residential treatment centers and subsequently followed up 6 months after enrollment. Compared to chemically dependent teenagers without LD, those with LD were twice as likely to re-use substances at least once by follow-up. LD teenagers were more likely to attend Alcoholics/Narcotics Anonymous if they had prior admissions to treatment programs and longer treatment length. LD teenagers who completed treatment also experienced a greater decrease in current depression compared to LD teenagers not completing the treatment. This study is the first to consider outcomes of substance abuse treatment for adolescents with LD and contributes to the growing literature on comorbidity and substance abuse treatment.

Knight, Danica K.; Broome, Kirk M.; Edwards, Jennifer R.; Flynn, Patrick M.

2009-01-01

Staff turnover is a significant issue within substance abuse treatment, with implications for service delivery and organizational health. This study examined factors associated with turnover among supervisors in outpatient substance abuse treatment. Turnover was conceptualized as being an individual response to organizational-level influences, and predictors represent aggregate program measures. Participants included 532 staff (including 467 counselors and 65 clinical/program directors) from 90 programs in four regions of the USA. Using logistic regression, analyses of structural factors indicated that programs affiliated with a parent organization and those providing more counseling hours to clients had higher turnover rates. When measures of job attitudes were included, only parent affiliation and collective appraisal of satisfaction were related to turnover. Subsequent analyses identified a trend toward increased supervisory turnover when satisfaction was low following the departure of a previous supervisor. These findings suggest that organizational-level factors can be influential in supervisory turnover. PMID:19949883

Efforts to understand how to improve the delivery of substance abuse treatment have led to a recent call for studies on the "business of addiction treatment." This study adapts an innovative survey tool to collect baseline management practice data from 147 addiction treatment programs enrolled in the Network for the Improvement of Addiction Treatment 200 project. Measures of "good" management practice were strongly associated with days to treatment admission. Management practice scores were weakly associated with revenues per employee but were not correlated with operating margins. Better management practices were more prevalent among programs with a higher number of competitors in their catchment area.

SAT projects' effectiveness: managerial aspects

Discussion provided below in the text and on the presentation transparencies is based on hands-on experience of SAT projects' implementation which have been or being conducted in several countries, and intended to develop or upgrade NPP personnel training. We will 'risk' to say that no comprehensive system, training system in particular, can work without feedback. A powerful tool to establish a controllability of a training process is to measure (using certain criteria) trainees' performance., training process, employees' qualification, on-job human performance, overall plant performance, and then (using certain algorithms) to provide feedback control to training and the whole organization with clear understanding and grading whether we deal with training-related root causes or not. In this way a training effectiveness may be considered as a feature that shows to what extent training is producing a desired result (e.g. developing needed skills, knowledge and attitudes, enhancing quality, safety and productivity, establishing cost-effective training, etc.). In order to design a training system with the features of feedback control, the SAT projects are implemented. In this respect SAT is more 'systems' rather than 'systematic' approach. Obviously, the criteria to evaluate a training system should be established. SAT implementation may be considered as a corrective action to fix the problems associated with the deficiencies in personnel competence or ineffectiveness of training system. But each corrective action or initiative related to a training system development should be generated and justified through normal process of evaluation and systematic needs analysis. The effectiveness of a training development project shall be evaluated against the overall goal and specific objectives of a project. The ultimate overall goal of SAT project implementation is to develop or upgrade NPP personnel training programmes and the whole training system in order to provide

First Nations and Inuit youth who abuse solvents are one of the most highly stigmatized substance-abusing groups in Canada. Drawing on a residential treatment response that is grounded in a culture-based model of resiliency, this article discusses the cultural implications for psychiatry's individualized approach to treating mental disorders. A systematic review of articles published in The Canadian Journal of Psychiatry during the past decade, augmented with a review of Canadian and international literature, revealed a gap in understanding and practice between Western psychiatric disorder-based and Aboriginal culture-based approaches to treatment and healing from substance abuse and mental disorders. Differing conceptualizations of mental health and substance abuse are discussed from Western psychiatric and Aboriginal worldviews, with a focus on connection to self, community, and political context. Applying an Aboriginal method of knowledge translation-storytelling-experiences from front-line workers in a youth solvent abuse treatment centre relay the difficulties with applying Western responses to Aboriginal healing. This lends to a discussion of how psychiatry can capitalize on the growing debate regarding the role of culture in the treatment of Aboriginal youth who abuse solvents. There is significant need for culturally competent psychiatric research specific to diagnosing and treating First Nations and Inuit youth who abuse substances, including solvents. Such understanding for front-line psychiatrists is necessary to improve practice. A health promotion perspective may be a valuable beginning point for attaining this understanding, as it situates psychiatry's approach to treating mental disorders within the etiology for Aboriginal Peoples.

CarbonSat Constellation

Sun, Wei; Tobehn, Carsten; Ernst, Robert; Bovensmann, Heinrich; Buchwitz, Michael; Burrows, John P.; Notholt, John

1 Carbon dioxide (CO2) and methane (CH4) are the most important manmade greenhouse gases (GHGs) which are driving global climate change. Currently, the CO2 measurements from the ground observing network are still the main sources of information but due to the limited number of measurement stations the coverage is limited. In addition, CO2 monitoring and trading is often based mainly on bottom-up calculations and an independent top down verification is limited due to the lack of global measurement data with local resolution. The first CO2 and CH4 mapping from SCIAMACHY on ENVISAT shows that satellites add important missing global information. Current GHG measurement satellites (GOSAT)are limited either in spatial or temporal resolution and coverage. These systems have to collect data over a year or even longer to produce global regional fluxes products. Conse-quently global, timely, higher spatial resolution and high accuracy measurement are required for: 1. A good understanding of the CO2 and CH4 sources and sinks for reliable climate predic-tion; and 2. Independent and transparent verification of accountable sources and sinks in supporting Kyoto and upcoming protocols The CarbonSat constellation idea comes out the trade off of resolution and swath width during CarbonSat mission definition studies. In response to the urgent need to support the Kyoto and upcoming protocols, a feasibility study has been carried out. The proposed solution is a constellation of five CarbonSat satellites in 614km LTAN 13:00, which is able to provide global, daily CO2 and CH4 measurement everywhere on the Earth with high spatial resolution 2 × 2 km and low uncertainty lt;2ppm (CO2) and lt;8ppb (CH4). The unique global daily measurement capability significantly increases the number of cloud free measurements, which enables more reliable services associated with reduced uncertainty, e.g. to 0.15ppm (CO2) per month in 10km and even more timely products.

Many authors have suggested adapting treatment programs to the specific needs of sexual abusers. However, little research has been conducted to understand what these patients seek in therapy or what elements play a key role in keeping them in treatment. In this pilot study, fifteen (N=15) pedophile sexual abusers from La Macaza clinic for sexual abusers were interviewed. Plan analysis was used to investigate the most prevalent components involved in staying in or leaving therapy. Results suggest that many components involved in the plans leading to doing and to avoiding treatment were similar. Differences were found in regards to the outcome of confrontations with the therapists, a tendency to isolate and overcomply, guilt related to the abuse, a need for a stable environment, and a need to be accepted. These results are discussed along with possible ways to improve the patients' involvement in treatment.

Technology-based applications represent a promising method for providing efficacious, widely available interventions to substance abuse treatment patients. However, limited access to communication technology (i.e., mobile phones, computers, internet, and e-mail) could significantly impact the feasibility of these efforts, and little is known regarding technology utilization in substance abusing populations. A survey was conducted to characterize utilization of communication technology in 266 urban, substance abuse treatment patients enrolled at eight drug-free, psychosocial or opioid-replacement therapy clinics. Survey participants averaged 41 years of age and 57% had a yearly household income of less than $15,000. The vast majority reported access to a mobile phone (91%), and to SMS text messaging (79%). Keeping a consistent mobile phone number and yearly mobile contract was higher for White participants, and also for those with higher education, and enrolled in drug-free, psychosocial treatment. Internet, e-mail, and computer use was much lower (39-45%), with younger age, higher education and income predicting greater use. No such differences existed for the use of mobile phones however. Concern regarding the digital divide for marginalized populations appears to be disappearing with respect to mobile phones, but still exists for computer, internet, and e-mail access and use. Results suggest that mobile phone and texting applications may be feasibly applied for use in program-client interactions in substance abuse treatment. Careful consideration should be given to frequent phone number changes, access to technology, and motivation to engage with communication technology for treatment purposes.

The effects of a Self-Alert Training (SAT program in adults with ADHD

Directory of Open Access Journals (Sweden)

Simona eSalomone

2015-02-01

Full Text Available Attention-Deficit/Hyperactivity Disorder (ADHD, a neuropsychiatric condition characterised by attention and impulsivity problems, is one of the most common behavioral disorders. The first line of treatment for ADHD is psychostimulant medication, but this has limited effectiveness, particularly in adults, and is often associated with adverse side-effects. Thus, it is imperative that new non-pharmaceutical approaches to treatment are developed. This study aims to evaluate the impact of a non-pharmacological Self-Alert Training (SAT intervention on ADHD symptom prevalence, psychological and cognitive functioning, and on everyday functional impairment in adults with ADHD. Fifty-one adult participants with a current diagnosis of ADHD were randomized to either SAT or a Control Training (CT program. They were assessed at baseline, immediately following the 5-week training period, and after 3 months using ADHD symptoms scales, as well as a series of neuropsychological tests and psychological questionnaires. Subjective ratings of everyday life attention and memory problems were also collected. The SAT group showed significant improvements in ADHD inattentive and impulsive symptoms, depressive symptoms and in self-efficacy ratings compared to the CT group at both post-training and at the 3-month assessment. Pre-post improvements in SAT participants on untrained cognitive tasks measuring selective attention and executive functions were also observed. Finally, the SAT group reported improved subjective ratings of everyday life attention at both assessment points. This pattern of results suggests that SAT may be beneficial in treating ADHD symptoms as well as psychological and cognitive impairments in adult ADHD. A large-scale randomized controlled trial is needed.

Herbst, Karen L; Ussery, Christopher; Eekema, Alyna

2017-09-20

Background Lipedema is a common painful subcutaneous adipose tissue (SAT) disorder in women affecting the limbs. SAT therapy is a manual therapy to improve soft tissue quality. Objective Determine if SAT therapy improves pain and structure of lipedema SAT. Design Single arm prospective pilot study. Setting Academic medical center. Patients Seven women, 46 ± 5 years, weight 90 ± 19 kg, with lipedema. Intervention Twelve 90-min SAT therapy sessions over 4 weeks. Outcomes Dual X-ray absorptiometry (DXA) scans, SAT ultrasound (Vevo 2100), leg volumetrics, skin caliper assessment, tissue exam, weight, resting metabolic rate, pain assessment, lower extremity functional scale (LEFS) and body shape questionnaire (BSQ) at baseline and end of study. Results Weight, resting metabolic rate and BSQ did not change significantly. Limb fat over total body fat mass (p = 0.08) and trunk fat over total body mass trended down from baseline (p = 0.08) by DXA. Leg volume and caliper assessments in eight of nine areas (p < 0.007), LEFS (p = 0.002) and average pain (p = 0.007) significantly decreased from baseline. Fibrosis significantly decreased in the nodules, hips and groin. Ultrasound showed improved SAT structure in some subjects. Side effects included pain, bruising, itching, swelling and gastroesophageal reflux disease. All women said they would recommend SAT therapy to other women with lipedema. Limitations Small number of subjects. Conclusion SAT therapy in 4 weeks improved tissue structure, perceived leg function, and volume although shape was not affected. While side effects of SAT therapy were common, all women felt the therapy was beneficial.

Can MDMA play a role in the treatment of substance abuse?

Science.gov (United States)

Jerome, Lisa; Schuster, Shira; Yazar-Klosinski, B Berra

2013-03-01

A wider array of treatments are needed for people with substance abuse disorders. Some psychedelic compounds have been assessed as potential substance abuse treatments with promising results. MDMA may also help treat substance abuse based on shared features with psychedelic compounds and recent reports indicating that MDMAassisted psychotherapy can reduce symptoms of PTSD. Narrative reports and data from early investigations found that some people reduced or eliminated their substance use after receiving MDMA, especially in a therapeutic setting. MDMA is a potent monoamine releaser with sympathomimetic effects that may indirectly activate 5-HT2A receptors. It increases interpersonal closeness and prosocial feelings, potentially through oxytocin release. Findings suggest that ecstasy, material represented as containing MDMA, is associated with deleterious long-term effects after heavy lifetime use, including fewer serotonin transporter sites and impaired verbal memory. Animal and human studies demonstrate moderate abuse liability for MDMA, and this effect may be of most concern to those treating substance abuse disorders. However, subjects who received MDMA-assisted psychotherapy in two recent clinical studies were not motivated to seek out ecstasy, and tested negative in random drug tests during follow-up in one study. MDMA could either directly treat neuropharmacological abnormalities associated with addiction, or it could indirectly assist with the therapeutic process or reduce symptoms of comorbid psychiatric conditions, providing a greater opportunity to address problematic substance use. Studies directly testing MDMA-assisted psychotherapy in people with active substance abuse disorder may be warranted.

NASA's PhoneSat project tests whether spacecraft can be built using smartphones to launch the lowest-cost satellites ever flown in space. Each PhoneSat nanosatellite is one cubesat unit - a satellite in a 10 cm (approx. 4 inches) cube or about the size of a tissue box - and weighs approximately 1 kg (2.2 pounds). Engineers believe PhoneSat technology will enable NASA to launch multiple new satellites capable of conducting science and exploration missions at a small fraction of the cost of conventional satellites.

Solving SAT problem by heuristic polarity decision-making algorithm

Institute of Scientific and Technical Information of China (English)

无

2007-01-01

This paper presents a heuristic polarity decision-making algorithm for solving Boolean satisfiability (SAT). The algorithm inherits many features of the current state-of-the-art SAT solvers, such as fast BCP, clause recording, restarts, etc. In addition, a preconditioning step that calculates the polarities of variables according to the cover distribution of Karnaugh map is introduced into DPLL procedure, which greatly reduces the number of conflicts in the search process. The proposed approach is implemented as a SAT solver named DiffSat. Experiments show that DiffSat can solve many "real-life" instances in a reasonable time while the best existing SAT solvers, such as Zchaff and MiniSat, cannot. In particular, DiffSat can solve every instance of Bart benchmark suite in less than 0.03 s while Zchaff and MiniSat fail under a 900 s time limit. Furthermore, DiffSat even outperforms the outstanding incomplete algorithm DLM in some instances.

2012-01-01

Three substance abuse treatment centres set up a benchmarking project for routine outcome management (ROM) of structured cognitive behavioral treatments for outpatients with a substance use disorder. To present the results of five years benchmarking. All patients were included at intake and the follow-up assessment was performed by a call-center nine months later. Twice a year aggregated data were fed back to management and treatment teams. Since 2005, clinical outcome data, including substance abuse data, have been collected for more than half of all 15.786 treated patients. At follow-up, nine months after intake, 23% was abstinent, 28% reported moderate substance use and 49% reported excessive substance use. The Dutch centres for the treatment of substance abuse were successful in setting up ROM projects to monitor and compare the development and the effects of outpatient addiction treatments. The clinical results are acceptable and correspond to the results of the American project called match. It is not yet clear whether the biannual feedback of aggregated outcomes to management and treatment teams has contributed to the creation of learning organisations, but it has provided transparency and has made it possible for teams to learn from the outcomes.

Assessing the Impact of Recycled Water Quality and Clogging on Infiltration Rates at A Pioneering Soil Aquifer Treatment (SAT Site in Alice Springs, Northern Territory (NT, Australia

Directory of Open Access Journals (Sweden)

Karen E. Barry

2017-03-01

Full Text Available Infiltration techniques for managed aquifer recharge (MAR, such as soil aquifer treatment (SAT can facilitate low-cost water recycling and supplement groundwater resources. However there are still challenges in sustaining adequate infiltration rates in the presence of lower permeability sediments, especially when wastewater containing suspended solids and nutrients is used to recharge the aquifer. To gain a better insight into reductions in infiltration rates during MAR, a field investigation was carried out via soil aquifer treatment (SAT using recharge basins located within a mixture of fine and coarse grained riverine deposits in Alice Springs, Northern Territory, Australia. A total of 2.6 Mm3 was delivered via five SAT basins over six years; this evaluation focused on three years of operation (2011–2014, recharging 1.5 Mm3 treated wastewater via an expanded recharge area of approximately 38,400 m2. Average infiltration rates per basin varied from 0.1 to 1 m/day due to heterogeneous soil characteristics and variability in recharge water quality. A treatment upgrade to include sand filtration and UV disinfection (in 2013 prior to recharge improved the average infiltration rate per basin by 40% to 100%.

2009-01-01

This research was conducted at a Substance Abuse Forum designed to address local community needs by focusing on Evidence-Based Practices (EBPs) in addiction treatment. The purpose of the study was to assess substance abuse treatment professionals’ readiness to adopt EBPs, experience with EBPs, and attitudes toward EBPs, as well as agency support for EBPs. A total of 119 addiction treatment providers completed pre-test measures, and 82% completed a post-test. Eighty-three percent of participants reported using some EBPs in the past year, and 75% reported currently using EBPs. Participants who were currently licensed or certified in addictions had less negative attitudes toward EBPs than those without credentials. While respondents reported agency support for EBPs, most expressed interest in further training. This study underscores the movement toward EBPs in addiction treatment and the need for effective dissemination and training in this area. PMID:18724657

Full Text Available Sally StevensSouthwest Institute for Research on Women (SIROW and Department of Gender and Women’s Studies (GWS, University of Arizona, Tucson, AZ, USAAbstract: Research on the incidence, etiology and substance abuse treatment needs of lesbian, bisexual and transgender (LBT women is limited. Most research indicates higher levels of alcohol and drug abuse among these populations compared to their heterosexual counterparts, with recent research indicating that substance abuse is a particular concern for transgender individuals and an increasing problem among younger LBT individuals. Risk factors and reasons for substance abuse among sexual minority women are similar to those of heterosexual women, yet are substantially complicated by issues of family rejection and lack of social support, stigma and minority stress, as well as abuse and harassment. Historically, substance abuse prevention, early intervention, and clinical treatment programs were designed to meet the needs of the sexual majority population with relatively few programs designed to incorporate the specific needs of sexual minorities. This article reviews findings from previous studies and utilizes new data collected from community-based and residential substance abuse treatment programs to (1 examine issues relevant to LBT women and substance use, and (2 make recommendations for tailoring substance abuse treatment programs to meet the needs of these populations.Keywords: lesbian, bisexual, transgender, substance abuse, family rejection, social support, stigma, minority stress, abuse, harassment

Robertson, Glen A.; Young, David; Kim, Tony; Houts, Mike

2013-01-01

Technologies under development for the proposed Nuclear Cryogenic Propulsion Stage (NCPS) will require an un-crewed demonstration mission before they can be flight qualified over distances and time frames representative of a crewed Mars mission. In this paper, we describe a Massively Clustered CubeSats platform, possibly comprising hundreds of CubeSats, as the main payload of the NCPS demo mission. This platform would enable a mechanism for cost savings for the demo mission through shared support between NASA and other government agencies as well as leveraged commercial aerospace and academic community involvement. We believe a Massively Clustered CubeSats platform should be an obvious first choice for the NCPS demo mission when one considers that cost and risk of the payload can be spread across many CubeSat customers and that the NCPS demo mission can capitalize on using CubeSats developed by others for its own instrumentation needs. Moreover, a demo mission of the NCPS offers an unprecedented opportunity to invigorate the public on a global scale through direct individual participation coordinated through a web-based collaboration engine. The platform we describe would be capable of delivering CubeSats at various locations along a trajectory toward the primary mission destination, in this case Mars, permitting a variety of potential CubeSat-specific missions. Cameras on various CubeSats can also be used to provide multiple views of the space environment and the NCPS vehicle for video monitoring as well as allow the public to "ride along" as virtual passengers on the mission. This collaborative approach could even initiate a brand new Science, Technology, Engineering and Math (STEM) program for launching student developed CubeSat payloads beyond Low Earth Orbit (LEO) on future deep space technology qualification missions.

Mejía, Bertha; Zea, Paloma; Romero, Martha; Saldívar, Gabriela

2015-02-09

In the past decade, several studies have focused on the treatment needs of female inmates with substance abuse problems. An important finding has been that these women are more likely to report histories of sexual, physical, and emotional abuse-at rates varying from 77% to 90%. The trauma resulting from this kind of abuse is a key contributing factor in behavioral problems in adolescence and subsequent delinquency, substance abuse, and criminality in adulthood. This was a retrospective clinical study. A convenience sample of 112 women who entered the program's treatment groups consecutively for one year form part of the study. Information on traumatic events was obtained using some questions from the Initial Trauma Review. It explores whether the participant experienced physical abuse, sexual abuse, disasters, automobile accidents, or witnessed violence under the age of 18. It also examines experiences as an adult, including sexual and physical abuse, attacks by others who are not intimate partners, and abuse by authorities. Revictimization in sexual abuse was found in 78.1% of participants. Significant differences were identified between women who had experienced a traumatic sexual event from a person five years their senior before the age of 18 and then suffered from sexual violence as an adult, and women who had never undergone either of these events (x(2) = 11.3, df 112/1, p = abuse, the figure was 82.17%. Differences were observed between women who were revictimized through physical abuse before and after the age of 18 (x(2) = 5.91, df 112/1, p = child and subsequently physical violence from their parents, and women who had not undergone either of these events (x(2) = 3.48, df 112/1, p = <.05). Investment in treatment in these areas during the prison sentence and after release may contribute to preventing these women from become repeat offenders.

A new assay for determining ganglioside sialyltransferase activities lactosylceramide-2,3-sialyltransferase (SAT I and monosialylganglioside-2,3-sialyltransferase (SAT IV.

Directory of Open Access Journals (Sweden)

Cynthia Q Sun

Full Text Available A new assay for the determination of lactosylceramide-2,3-sialyltransferase (SAT I, EC 2.4.99.9 and monosialoganglioside sialyltransferase (SAT IV, EC 2.4.99.2 is described. The assay utilised the commercially available fluorophore labelled sphingolipids, boron dipyrromethene difluoride (BODIPY lactosylceramide (LacCer, and BODIPY-monosialotetrahexosylganglioside (GM1 as the acceptor substrates, for SAT I and SAT IV, respectively. HPLC coupled with fluorescence detection was used to analyse product formation. The analysis was performed in a quick and automated fashion. The assay showed good linearity for both BODIPY sphingolipids with a quantitative detection limit of 0.05 pmol. The high sensitivity enabled the detection of SAT I and SAT IV activities as low as 0.001 μU, at least 200 fold lower than that of most radiometric assays. This new assay was applied to the screening of SAT I and SAT IV activities in ovine and bovine organs (liver, heart, kidney, and spleen. The results provided evidence that young animals, such as calves, start to produce ganglioside sialyltransferases as early as 7 days after parturition and that levels change during maturation. Among the organs tested from a bovine source, spleen had the highest specific ganglioside sialyltransferase activity. Due to the organ size, the greatest total ganglioside sialyltransferase activities (SAT I and SAT IV were detected in the liver of both bovine and ovine origin.

PhoneSat 2.4, carried into space on November 19, 2013 aboard a Minotaur I rocket from the Mid-Atlantic Regional Spaceport at NASAs Wallops Flight Facility in Virginia, is the first of the PhoneSat family to use a two-way S-band radio to allow engineers to command the satellite from Earth. This mission also serves as a technology demonstration for a novel attitude determination and control system (ADCS) that establishes and stabilizes the satellites attitude relative to Earth. Unlike the earlier PhoneSats that used a Nexus One, PhoneSat 2.4 uses the Nexus S smartphone, which runs Googles Android operating system, and is made by Samsung Electronics Co., Suwon, So. Korea. The smartphone provides many of the functions needed by the satellite such as a central computer, data memory, ready-made interfaces for communications, navigation and power all pre-assembled in a rugged electronics package.

Enhancing SAT-Based Test Pattern Generation

Institute of Scientific and Technical Information of China (English)

LIU Xin; XIONG You-lun

2005-01-01

This paper presents modeling tools based on Boolean satisfiability (SAT) to solve problems of test generation for combinational circuits. It exploits an added layer to maintain circuit-related information and value justification relations to a generic SAT algorithm. It dovetails binary decision graphs (BDD) and SAT techniques to improve the efficiency of automatic test pattern generation (ATPG). More specifically, it first exploits inexpensive reconvergent fanout analysis of circuit to gather information on the local signal correlation by using BDD learning, then uses the above learned information to restrict and focus the overall search space of SAT-based ATPG. Its learning technique is effective and lightweight. The experimental results demonstrate the effectiveness of the approach.

Over the last decade, consumer technology has vastly improved its performances, become more affordable and reduced its size. Modern day smartphones offer capabilities that enable us to figure out where we are, which way we are pointing, observe the world around us, and store and transmit this information to wherever we want. These capabilities are remarkably similar to those required for multi-million dollar satellites. The PhoneSat project at NASA Ames Research Center is building a series of CubeSat-size spacecrafts using an off-the-shelf smartphone as its on-board computer with the goal of showing just how simple and cheap space can be. Since the PhoneSat project started, different suborbital and orbital flight activities have proven the viability of this revolutionary approach. In early 2013, the PhoneSat project launched the first triage of PhoneSats into LEO. In the five day orbital life time, the nano-satellites flew the first functioning smartphone-based satellites (using the Nexus One and Nexus S phones), the cheapest satellite (a total parts cost below $3,500) and one of the fastest on-board processors (CPU speed of 1GHz). In this paper, an overview of the PhoneSat project as well as a summary of the in-flight experimental results is presented.

The goal of KidSat was to provide young students with the opportunity to participate directly in the NASA space program and to enhance learning in the process. The KidSat pilot project was focused on using a color digital camera, mounted on the space shuttle, to take pictures of the Earth. These could be used to enhance middle school curricula. The project not only benefited middle school students, who were essentially the Science Team, responsible for deciding where to take pictures, but it also benefited high school students and undergraduates, who were essentially the Project Team, responsible for the development and implementation of the project. KidSat flew on three missions as part of the pilot project: STS-76, STS-81, and STS-86. This document describes the goals, project elements, results, and data for the three KidSat missions that made up the pilot program.

Barlow, J; Johnston, I; Kendrick, D; Polnay, L; Stewart-Brown, S

2006-07-19

Child physical abuse and neglect are important public health problems and recent estimates of their prevalence suggest that they are considerably more common than had hitherto been realised. Many of the risk factors for child abuse and neglect are not amenable to change in the short term. Intervening to change parenting practices may, however, be important in its treatment. Parenting programmes are focused, short-term interventions aimed at improving parenting practices in addition to other outcomes (many of which are risk factors for child abuse e.g. parental psychopathology, and parenting attitudes and practices), and may therefore be useful in the treatment of physically abusive or neglectful parents. To assess the efficacy of group-based or one-to-one parenting programmes in addressing child physical abuse or neglect. A range of biomedical and social science databases were searched including MEDLINE, EMBASE, CINAHL, PsychINFO, Sociofile, Social Science Citation Index, ASSIA, the Cochrane Library, Campbell Library (including SPECTR and CENTRAL), National Research Register (NRR) and ERIC, from inception to May 2005. Only randomised controlled trials or randomised studies that compared two treatments were included. Studies had to include at least one standardised instrument measuring some aspect of abusive or neglectful parenting. In the absence of studies using objective assessments of child abuse, studies reporting proxy measures of abusive parenting were included. Only studies evaluating the effectiveness of standardised group-based or one-to-one parenting programmes aimed at the treatment of physical child abuse or neglect were included. Studies were also only eligible for inclusion if they had targeted parents of children aged 0-19 years who had been investigated for physical abuse or neglect. The treatment effect for each outcome in each study was standardised by dividing the mean difference in post-intervention scores for the intervention and treatment

A study was performed that evaluated the feasibility of Ka-band communication system to provide CubeSat/SmallSat high rate science data downlink with ground antennas ranging from the small portable 1.2m/2.4m to apertures 5.4M, 7.3M, 11M, and 18M, for Low Earth Orbit (LEO) to Lunar CubeSat missions. This study included link analysis to determine the data rate requirement, based on the current TRL of Ka-band flight hardware and ground support infrastructure. Recent advances in Ka-band transceivers and antennas, options of portable ground stations, and various coverage distances were included in the analysis. The link/coverage analysis results show that Cubesat/Smallsat missions communication requirements including frequencies and data rates can be met by utilizing Near Earth Network (NEN) Ka-band support with 2 W and high gain (>6 dBi) antennas.

This study of 23 boys (ages 6 to 14) in a residential psychiatric treatment program found nine of the boys were encopretic (27 times the incidence of encopresis in the general population of boys 10-12). Seven of the nine boys had histories of sexual abuse by males, suggesting that encopresis may be a marker of sexual abuse. (DB)

Predicting substance-abuse treatment providers' communication with clients about medication assisted treatment: a test of the theories of reasoned action and planned behavior.

Science.gov (United States)

Roberto, Anthony J; Shafer, Michael S; Marmo, Jennifer

2014-01-01

The purpose of this investigation is to determine if the theory of reasoned action (TRA) and theory of planned behavior (TPB) can retrospectively predict whether substance-abuse treatment providers encourage their clients to use medicated-assisted treatment (MAT) as part of their treatment plan. Two-hundred and ten substance-abuse treatment providers completed a survey measuring attitudes, subjective norms, perceived behavioral control, intentions, and behavior. Results indicate that substance-abuse treatment providers have very positive attitudes, neutral subjective norms, somewhat positive perceived behavioral control, somewhat positive intentions toward recommending MAT as part of their clients' treatment plan, and were somewhat likely to engage in the actual behavior. Further, the data fit both the TRA and TPB, but with the TPB model having better fit and predictive power for this target audience and behavior. The theoretical and practical implications for the developing messages for substance-abuse treatment providers and other health-care professionals who provide treatment to patients with substance use disorders are discussed.

Solving the SAT problem using Genetic Algorithm

Directory of Open Access Journals (Sweden)

Arunava Bhattacharjee

2017-08-01

Full Text Available In this paper we propose our genetic algorithm for solving the SAT problem. We introduce various crossover and mutation techniques and then make a comparative analysis between them in order to find out which techniques are the best suited for solving a SAT instance. Before the genetic algorithm is applied to an instance it is better to seek for unit and pure literals in the given formula and then try to eradicate them. This can considerably reduce the search space, and to demonstrate this we tested our algorithm on some random SAT instances. However, to analyse the various crossover and mutation techniques and also to evaluate the optimality of our algorithm we performed extensive experiments on benchmark instances of the SAT problem. We also estimated the ideal crossover length that would maximise the chances to solve a given SAT instance.

Attachment as an organizer of behavior: implications for substance abuse problems and willingness to seek treatment

Directory of Open Access Journals (Sweden)

Troutman Beth

2006-11-01

Full Text Available Abstract Background Attachment theory allows specific predictions about the role of attachment representations in organizing behavior. Insecure attachment is hypothesized to predict maladaptive emotional regulation whereas secure attachment is hypothesized to predict adaptive emotional regulation. In this paper, we test specific hypotheses about the role of attachment representations in substance abuse/dependence and treatment participation. Based on theory, we expect divergence between levels of maladaptive functioning and adaptive methods of regulating negative emotions. Methods Participants for this study consist of a sample of adoptees participating in an ongoing longitudinal adoption study (n = 208. The Semi-Structured Assessment of the Genetics of Alcohol-II 41 was used to determine lifetime substance abuse/dependence and treatment participation. Attachment representations were derived by the Adult Attachment Interview [AAI; 16]. We constructed a prior contrasts reflecting theoretical predictions for the association between attachment representations, substance abuse/dependence and treatment participation. Results Logistic regression was used to test our hypotheses. As predicted, individuals classified as dismissing, preoccupied or earned-secure reported the highest rates of substance abuse/dependence. Individuals classified as dismissing reported significantly lower rates of treatment participation despite their high rates of substance abuse/dependence. As expected, the continuous-secure group reported lowest rates of both substance abuse/dependence and treatment participation. Conclusion The findings from this study identify attachment representations as an influential factor in understanding the divergence between problematic substance use and treatment utilization. The findings further imply that treatment may need to take attachment representations into account to promote successful recovery.

Sims, William H.

2015-01-01

This paper will discuss a proposed CubeSat size (3 Units / 6 Units) telemetry system concept being developed at Marshall Space Flight Center (MSFC) in cooperation with Auburn University. The telemetry system incorporates efficient, high-bandwidth communications by developing flight-ready, low-cost, PROTOFLIGHT software defined radio (SDR) payload for use on CubeSats. The current telemetry system is slightly larger in dimension of footprint than required to fit within a 0.75 Unit CubeSat volume. Extensible and modular communications for CubeSat technologies will provide high data rates for science experiments performed by two CubeSats flying in formation in Low Earth Orbit. The project is a collaboration between the University of Alabama in Huntsville and Auburn University to study high energy phenomena in the upper atmosphere. Higher bandwidth capacity will enable high-volume, low error-rate data transfer to and from the CubeSats, while also providing additional bandwidth and error correction margin to accommodate more complex encryption algorithms and higher user volume.

Mothers who abuse substances are likely to have insecure emotional attachment with their children, placing their children at risk for social-emotional and psychiatric conditions. Sobriety does not inevitably improve parenting. We tested recruitment methods, audiovisual (AV) recording procedures, the protocol for identifying child abuse risk, the coding of mother-child interactions, and retention of the sample for repeated measures as the first phase in examining mother-child relational quality of women in substance abuse treatment. This innovative study involved AV recordings to capture the in-vivo mother-child interactional behaviors that were later coded and analyzed for mean scores on the 64-item Parent-Child Relational Quality Assessment. Repeated measurement was planned during treatment and two months after discharge from treatment. The pilot involved a small sample (n = 11) of mother-child (interaction behaviors were identified. Mothers showed less enthusiasm and creativity but matched their child's emotional state. The children showed appropriate motor skill items and attachment behaviors. The dyad coding showed less mutual enjoyment between the mother and child. Eight of the participants could not be located for the second measurement despite multiple contact methods. AV recordings capture rich, descriptive information that can be coded for interactional quality analysis. Repeated measurement with this cohort was not feasible, thus needing to assess for additional/more frequent contacts to maintain the sample.

Camp, J M; Krakow, M; McCarty, D; Argeriou, M

1992-01-01

There is increased interest in documenting the characteristics and treatment outcomes of clients served with Alcohol, Drug Abuse, and Mental Health Block Grant funds. The evolution of federal client-based management systems for substance abuse treatment services demonstrates that data collection systems are important but require continued support. A review of the Massachusetts substance abuse management information system illustrates the utility of a client-based data set. The development and implementation of a comprehensive information system require overcoming organizational barriers and project delays, fostering collaborative efforts among staff from diverse agencies, and employing considerable resources. In addition, the need to develop mechanisms for increasing the reliability of the data and ongoing training for the users is presented. Finally, three applications of the management information system's role in shaping policy are reviewed: developing services for special populations (communities of color, women, and pregnant substance abusers, and injection drug users), utilizing MIS data for evaluation purposes, and determining funding allocations.

Link, Thomas W; Hefner, Jennifer L; Ford, Eric W; Huerta, Timothy R

2016-01-01

Website development for health care has only been prevalent in the last two and a half decades. The first websites were electronic versions of brochures providing hardly any interaction with the consumer or potential consumer. The percentage of consumers that use the internet during the decision-making process for health care providers continues to rise. As a result, the websites of health care providers are becoming more of a representation of the facility and creating an organizational image rather than a brochure-like informational page. The purpose of this study was to analyze substance abuse treatment center's websites in the State of California with the goal of informing the management of substance abuse centers regarding an effective and inexpensive means to closing the marketing gaps in the industry. This brief research report presents the results of employing an automated web-crawler to assess website quality along five dimensions: accessibility, content, marketing, technology, and usability score. The sample mean scores for all dimensions were between 4 and 6 on a 10-point scale. On average larger facilities had higher quality websites. The low mean scores on these dimensions indicate that that substance abuse centers have significant room for improvement of their website's. Efficiently spending marketing funds to increase the effectiveness of a treatment center's website can be a low cost way for even small facilities to increase market competitiveness.

2018-04-01

Sexual abuse has been widely studied as a risk factor in anorexia nervosa, but data on its influence on treatment outcomes are scarce. Hence, we compared short- and long-term outcomes of inpatient enhanced cognitive-behavioural therapy (CBT-E) in patients with anorexia nervosa who had and had not suffered sexual abuse. Eighty-one patients were recruited, and body mass index (BMI), Eating Disorder Examination, Brief Symptom Inventory, and Work and Social Adjustment Scale scores were recorded before and after treatment, and at 6- and 12-month follow-ups. Twenty patients (24.7%) reported experiencing childhood sexual abuse before anorexia nervosa onset, while 61 (75.3%) reported none. Both groups displayed similar characteristics before treatment, and similarly large increases in BMI, eating-disorder, general psychopathology, and work and social functioning from baseline to 12-month follow-up. Based on these findings, childhood sexual abuse does not appear to compromise outcomes in patients with anorexia nervosa treated via intensive CBT-E. Copyright © 2017 Elsevier B.V.

Wen, Y. L.; Yang, Y.; Zhang, H.; Lou, B.

2017-12-01

Nowadays, we were facing with water resource shortage along with water pollution. It was important to undertake the cost effective technology to treat polluted water whilst encourage water reuse. Soil aquifer treatment (SAT) was an efficient technology, using the infiltration process of mediation, adsorption and biodegradation on the pollutants in the environment to achieve the goal of recycling water. For a better understanding of the transport and attenuation of para-nitrophenol (P-NP) and the change of microbial community at the stress of p-nitrophenol in soil aquifer treatment system, two column experiments were operated to investigate the physical, chemical, and microbial dynamics. At the same time, the bio-augment method was used to enhance the SAT biodegradation system. The SAT column experiment was operated about 38 days, which demonstrated that two reduction zones were revealed at the middle of the column and the biodiversity of the microbial community could be destroyed under the P-NP stress. Absorption was the main removal mechanism according to the obtained experimental data. By using the displacement method, the BIO-SAT system was operated about 36 days, which showed perfect outcome for the P-NP removal at a higher concentration. From the PCR-DGGE and high throughput sequencing study, enhanced bacteria could form a stable biological community with indigenous communities. Through the Canonical Correspondence Analysis (CCA) microbial degradation and environmental factors, the results showed that the pH was a very important parameter affects the degradation of nitrophenol degradation bacteria. The metal ions under the condition of low concentration can promote the growth of microbial degradation. This study provide valuable result on the attenuation potential of for the bio-enhanced SAT system (BIO-SAT). (No Image Selected)

Full Text Available Rehabilitation and treatment centers are organizations that provide services for children and adolescents, with the main goal being to implement a “mental health” treatment plan for the individuals under their care. These organizations, which provide a continuous 24-hour service, may differ from one another in terms of the specific programs and treatment methods they apply. The Oğuz Kağan Köksal Children and Youth Center was established in the Adana Province to provide for the treatment and rehabilitation of girls between the ages of 8 and 18 who have been subject to abuse or neglect, who suffer from alcohol/substance abuse, who are in need of treatment for mental problems and/or who live on the streets. A study was made of 72 girls who had been admitted to the institution for treatment and rehabilitation since 2004 with a history abuse and neglect. The girls were assessed with the Beck Depression Inventory (BDI, the State Anxiety Inventory (STAI-I, the Trait Anxiety Inventory (STAI-II and the Maudsley Obsessive Compulsive Inventory (MOCI upon being admitted to the institution and at the end of their stay (i.e. their discharge. The differences between the mean admission and discharge scores of the girls in the BDI, STAI-I, STAI-II and MOCI assessments was determined to be statistically significant (p<0.001. According to the duration of stay groups (0–3 months; 4–6 months; 7–9 months and ≥10 months, a statistically significant difference was identified between the mean admission and discharge scores of children who remained in the institution for 3–7 months, with the post-treatment scores of the inventories being significantly lower in comparison to the baseline values (p≤0.05. These results suggest discharging patients from the center prior to their third month of stay or a stay period of longer than seven months does not affect with any significance the scores of the depression, anxiety and obsession inventories.

Saxena, Preeta; Messina, Nena; Grella, Christine E

2014-04-01

This study explores outcome variation among women offenders who participated in gender-responsive substance abuse treatment (GRT). In order to identify subgroups of participants that may differentially benefit from this treatment, secondary analyses examined the interaction between randomization into GRT and a history of abuse (physical/sexual) on depression and number of substances used post- treatment. The sample consisted of 115 incarcerated women assessed at baseline and 6- and 12-months post parole. Longitudinal regression showed that women reporting abuse randomized into GRT had significantly reduced odds of depression ( OR = .29, p < .05, 95% CI = .10 - .86) and lowered rates of number of substances used ( IRR = .52, p < .05, 95% CI = 0.28-0.98), in comparison to those who reported abuse and were randomized to the non-GRT group. GRT for women offenders who have experienced prior abuse would maximize the benefits of the trauma-informed, gender-sensitive intervention.

LESSONS FROM THE EVALUATION OF A PUBLIC OUT-PATIENT SUBSTANCE ABUSE TREATMENT PROGRAMME IN THE WESTERN CAPE

Directory of Open Access Journals (Sweden)

Strebel, Anna

2013-05-01

Full Text Available Substance abuse is widely regarded as a major health and social problem in South Africa, and particularly in the Western Cape (Corrigall, Ward, Stinson, Struthers, Frantz, Lund, Flisher & Joska, 2007; Myers, Fakier & Louw, 2009. The complex nature of patterns of substance abuse, as well as the particular problems associated with this abuse, has implications for the development and implementation of treatment interventions. The most common primary drug of abuse in the Western Cape amongst patients admitted to treatment programmes is methamphetamine (known locally as “tik” (Dada, Plüddemann, Parry, Vawda & Fourie, 2012. The previous decade saw a dramatic rise in methamphetamine (hereafter indicated as MA use, particularly among youths, with over half the patients in treatment for MA abuse being younger than 25 years (Plüddemann, Parry, Dada, Bhana, Bachoo & Fourie, 2010. MA is also often used in combination with other drugs, and this prevalence of poly-substance abuse needs to be taken into account in the planning of services (Harker, Kader, Myers, Falkier, Parry, Flisher, Peltzer, Ramlagan & Davids, 2008.

Full Text Available Aims Drug addiction is a mental, social, and economic problem that comes from abnormal and illicit consumption of substances such as alcohol, opium, hashish, and etc., making the addict psychologically and physiologically dependent to those substances. This study was designed and performed to evaluate the pattern of drug abuse change in the addicts visiting addiction treatment centers of Kashan City, Iran. Instrument & Methods This retrospective descriptive research was performed on 4066 persons referred to addiction treatment and harm reduction therapy centers, monitored by Kashan University of Medical Sciences, during 2004 to 2008. After coding, data were entered into the SPSS 16 software. Chi-square and one-way ANOVA was used to analyze the data. Findings The main reasons of the tendency to drugs were not having fun (72.5%, family problems (55% and not having knowledge (22.7%. The use of opium was the highest in all the years while the crack was used by 7.1% of drug addicts in 2004 and increased to 76% in 2007. 92.8% of drug abuses were through fumigation, 33.7% through injection, 48% orally and 8.6% through inhalants. Conclusion Youths are the most vulnerable age group to drug addiction. Easy access to illegal drugs, wrong friends, and curiosity are of the significant factors spreading drug addiction.

Effects of Methadone Maintenance Treatment on Decision-Making Processes in Heroin-Abusers: A Cognitive Modeling Analysis

Directory of Open Access Journals (Sweden)

Arash Khodadadi

2010-05-01

Full Text Available A B S T R A C TIntroduction: Although decision-making processes have become a principal target of study among addiction researchers, few researches are published according to effects of different treatment methods on the cognitive processes underlying decision making up to now. Utilizing cognitive modeling method, in this paper we examine the effects of Methadone maintenance treatment (MMT on cognitive processes underlying decision-making disorders in heroin-abusers. Methods: For this purpose, for the first time, we use the balloon analog risk task (BART to assess the decision-making ability of heroin-abusers before and after treatment and compare it to the non heroin-dependent subjects. Results: Results demonstrate that heroin-abusers show more risky behavior than other groups. But, there is no difference between the performance of heroin-abusers after 6 months of MMT and control group. Modeling subjects’ behavior in BART reveals that poor performance in heroin-abusers is due to reward-dependency and insensitivity to evaluation. Discussion: Results show that 6 months of MMT decreases reward-dependency and increases sensitivity to evaluation.

Wagenmans, Anouk; Van Minnen, Agnes; Sleijpen, Marieke; De Jongh, Ad

2018-01-01

Background : It is assumed that PTSD patients with a history of childhood sexual abuse benefit less from trauma-focused treatment than those without such a history. Objective : To test whether the presence of a history of childhood sexual abuse has a negative effect on the outcome of intensive trauma-focused PTSD treatment. Method : PTSD patients, 83% of whom suffered from severe PTSD, took part in a therapy programme consisting of 2 × 4 consecutive days of Prolonged Exposure (PE) and EMDR therapy (eight of each). In between sessions, patients participated in sport activities and psycho-education sessions. No prior stabilization phase was implemented. PTSD symptom scores of clinician-administered and self-administered measures were analysed using the data of 165 consecutive patients. Pre-post differences were compared between four trauma groups; patients with a history of childhood sexual abuse before age 12 (CSA), adolescent sexual abuse (ASA; i.e. sexual abuse between 12 and 18 years of age), sexual abuse (SA) at age 18 and over, or no history of sexual abuse (NSA). Results : Large effect sizes were achieved for PTSD symptom reduction for all trauma groups (Cohen's d  = 1.52-2.09). For the Clinical Administered PTSD Scale (CAPS) and the Impact of Event Scale (IES), no differences in treatment outcome were found between the trauma (age) groups. For the PTSD Symptom Scale Self Report (PSS-SR), there were no differences except for one small effect between CSA and NSA. Conclusions : The results do not support the hypothesis that the presence of a history of childhood sexual abuse has a detrimental impact on the outcome of first-line (intensive) trauma-focused treatments for PTSD.

The main CryoSat mission objectives are to measure the regional and basin-scale changes in the thickness of the sea-ice and, in the elevation of the ice sheets and mountain glaciers. Beside its ice-monitoring objective, CryoSat also provides valuable observations for the oceanographic community. The CryoSat data are processed by ESA both over the ocean and ice surfaces with two independent processors. These data need to be routinely Quality-Controlled and thoroughly Validated (QCV). Based on the QCV outcomes from ESA multi-national partners and the feedback from the scientific community, the data products continuously evolve in order to accommodate a wide range of users over the Sea ice, the Land Ice and the Ocean domains. The main objectives of this paper are to give an overview of main CryoSat QCV results and product improvements; as well as to present the processing algorithm upgrades being implemented for future ice and ocean Baselines.

Sex differences in drug abuse: Etiology, prevention, and treatment.

Science.gov (United States)

Evans, Suzette M; Reynolds, Brady

2015-08-01

This special issue exemplifies one of the major goals of the current editor of Experimental and Clinical Psychopharmacology (Dr. Suzette Evans): to increase the number of manuscripts that emphasize females and address sex differences. Taken together, these articles represent a broad range of drug classes and approaches spanning preclinical research to treatment to better understand the role of sex differences in drug abuse. While not all studies found sex differences, we want to emphasize that finding no sex difference is just as important as confirming one, and should be reported in peer-reviewed journals. It is our intention and hope that this special issue will further advance scientific awareness about the importance of accounting for sex differences in the study of substance abuse. Participant sex is an essential variable to consider in developing a more comprehensive understanding of substance abuse. Rather than viewing investigating sex differences as burdensome, investigators should seize this opportune area ripe for innovative research that is long overdue. (c) 2015 APA, all rights reserved).

The SAT protein (SATp) of porcine parvovirus (PPV) accumulates in the endoplasmic reticulum (ER), and SAT deletion induces the slow-spreading phenotype. The in vitro comparison of the wild-type Kresse strain and its SAT knockout (SAT - ) mutant revealed that prolonged cell integrity and late viral release are responsible for the slower spreading of the SAT - virus. During PPV infection, regardless of the presence or absence of SATp, the expression of downstream ER stress response proteins (Xbp1 and CHOP) was induced. However, in the absence of SATp, significant differences in the quantity and the localization of CHOP were detected, suggesting a role of SATp in the induction of irreversible ER stress in infected cells. The involvement of the induction of irreversible ER stress in porcine testis (PT) cell necrosis and viral egress was confirmed by treatment of infected cells by ER stress-inducing chemicals (MG132, dithiothreitol, and thapsigargin), which accelerated the egress and spreading of both the wild-type and the SAT - viruses. UV stress induction had no beneficial effect on PPV infection, underscoring the specificity of ER stress pathways in the process. However, induction of CHOP and its nuclear translocation cannot alone be responsible for the biological effect of SAT, since nuclear CHOP could not complement the lack of SAT in a coexpression experiment. IMPORTANCE SATp is encoded by an alternative open reading frame of the PPV genome. Earlier we showed that SATp of the attenuated PPV NADL-2 strain accumulates in the ER and accelerates virus release and spreading. Our present work revealed that slow spreading is a general feature of SAT - PPVs and is the consequence of prolonged cell integrity. PPV infection induced ER stress in infected cells regardless of the presence of SATp, as demonstrated by the morphological changes of the ER and expression of the stress response proteins Xbp1 and CHOP. However, the presence of SATp made the ER stress more severe and

We present the results of a study conducted by the National Academies of Sciences, Engineering, and Medicine. The study focused on the scientific potential and technological promise of CubeSats. We will first review the growth of the CubeSat platform from an education-focused technology toward a platform of importance for technology development, science, and commercial use, both in the United States and internationally. The use has especially exploded in recent years. For example, of the over 400 CubeSats launched since 2000, more than 80% of all science-focused ones have been launched just in the past four years. Similarly, more than 80% of peer-reviewed papers describing new science based on CubeSat data have been published in the past five years.We will then assess the technological and science promise of CubeSats across space science disciplines, and discuss a subset of priority science goals that can be achieved given the current state of CubeSat capabilities. Many of these goals address targeted science, often in coordination with other spacecraft, or by using sacrificial or high-risk orbits that lead to the demise of the satellite after critical data have been collected. Other goals relate to the use of CubeSats as constellations or swarms, deploying tens to hundreds of CubeSats that function as one distributed array of measurements.Finally, we will summarize our conclusions and recommendations from this study; especially those focused on nearterm investment that could improve the capabilities of CubeSats toward increased science and technological return and enable the science communities’ use of CubeSats.

Ducharme, Lori J; Chandler, Redonna K; Harris, Alex H S

2016-01-01

The National Institute on Alcohol Abuse and Alcoholism (NIAAA), National Institute on Drug Abuse (NIDA), and Veterans Health Administration (VHA) share an interest in promoting high quality, rigorous health services research to improve the availability and utilization of evidence-based treatment for substance use disorders (SUD). Recent and continuing changes in the healthcare policy and funding environments prioritize the integration of evidence-based substance abuse treatments into primary care and general medical settings. This area is a prime candidate for implementation research. Recent and ongoing implementation projects funded by these agencies are reviewed. Research in five areas is highlighted: screening and brief intervention for risky drinking; screening and brief intervention for tobacco use; uptake of FDA-approved addiction pharmacotherapies; safe opioid prescribing; and disease management. Gaps in the portfolios, and priorities for future research, are described. Published by Elsevier Inc.

CubeSat Integration into the Space Situational Awareness Architecture

Morris, K.; Wolfson, M.; Brown, J.

2013-09-01

Lockheed Martin Space Systems Company has recently been involved in developing GEO Space Situational Awareness architectures, which allows insights into how cubesats can augment the current national systems. One hole that was identified in the current architecture is the need for timelier metric track observations to aid in the chain of custody. Obtaining observations of objects at GEO can be supported by CubeSats. These types of small satellites are increasing being built and flown by government agencies like NASA and SMDC. CubeSats are generally mass and power constrained allowing for only small payloads that cannot typically mimic traditional flight capability. CubeSats do not have a high reliability and care must be taken when choosing mission orbits to prevent creating more debris. However, due to the low costs, short development timelines, and available hardware, CubeSats can supply very valuable benefits to these complex missions, affordably. For example, utilizing CubeSats for advanced focal plane demonstrations to support technology insertion into the next generation situational awareness sensors can help to lower risks before the complex sensors are developed. CubeSats can augment the planned ground and space based assets by creating larger constellations with more access to areas of interest. To aid in maintaining custody of objects, a CubeSat constellation at 500 km above GEO would provide increased point of light tracking that can augment the ground SSA assets. Key features of the Cubesat include a small visible camera looking along the GEO belt, a small propulsion system that allows phasing between CubeSats, and an image processor to reduce the data sent to the ground. An elegant communications network will also be used to provide commands to and data from multiple CubeSats. Additional CubeSats can be deployed on GSO launches or through ride shares to GEO, replenishing or adding to the constellation with each launch. Each CubeSat would take images of

The outcomes of counseling and testing programs related to human immunodeficiency virus (HIV) infection and risk of infection among injection drug users (IDUs) are not well known or understood. A counseling and testing outcome of potential public health importance is attaining admission to drug abuse treatment by those IDUs who are either infected or who are at high risk of becoming infected. The authors investigated factors related to admission to drug abuse treatment among 519 IDUs who received HIV counseling and testing from September 1987 through December 1990 at a men's prison and at community-based testing sites in Worcester, MA. By June 1991, 123 of the 519 IDUs (24 percent) had been admitted to treatment. Variables associated with their admission included a long history of drug injection, frequent recent drug injection, cleaning injection equipment using bleach, prior drug treatment, and a positive HIV test result. Logistic regression analyses, controlling for effects of recruitment site, year, sex, and area of residence, generally confirmed the associations. IDUs in the study population who were HIV-infected sought treatment or were admitted to treatment more frequently than those who were not infected. The results indicate that access to drug abuse treatment should be facilitated for high-risk IDUs and for those who have begun to inject drugs recently.

Vulnerability to drug abuse is related to both reward seeking and impulsivity, two constructs thought to have a biological basis in the prefrontal cortex (PFC). This review addresses similarities and differences in neuroanatomy, neurochemistry and behavior associated with PFC function in rodents and humans. Emphasis is placed on monoamine and amino acid neurotransmitter systems located in anatomically distinct subregions: medial prefrontal cortex (mPFC); lateral prefrontal cortex (lPFC); anterior cingulate cortex (ACC); and orbitofrontal cortex (OFC). While there are complex interconnections and overlapping functions among these regions, each is thought to be involved in various functions related to health-related risk behaviors and drug abuse vulnerability. Among the various functions implicated, evidence suggests that mPFC is involved in reward processing, attention and drug reinstatement; lPFC is involved in decision-making, behavioral inhibition and attentional gating; ACC is involved in attention, emotional processing and self-monitoring; and OFC is involved in behavioral inhibition, signaling of expected outcomes and reward/punishment sensitivity. Individual differences (e.g., age and sex) influence functioning of these regions, which, in turn, impacts drug abuse vulnerability. Implications for the development of drug abuse prevention and treatment strategies aimed at engaging PFC inhibitory processes that may reduce risk-related behaviors are discussed, including the design of effective public service announcements, cognitive exercises, physical activity, direct current stimulation, feedback control training and pharmacotherapies. A major challenge in drug abuse prevention and treatment rests with improving intervention strategies aimed at strengthening PFC inhibitory systems among at-risk individuals.

Reasons for dropout from drug abuse treatment: symptoms, personality, and motivation.

Science.gov (United States)

Ball, Samuel A; Carroll, Kathleen M; Canning-Ball, Monica; Rounsaville, Bruce J

2006-02-01

Previous research has identified risk factors for early attrition from substance abuse treatment, but has not assessed reasons for dropout from the client's perspective. Interview and self-report assessment data were collected from 24 clients who prematurely terminated outpatient treatment to evaluate their subjective reasons for dropping out and the association of these reasons with demographic and clinical variables. Items from scales indicating problems with client motivation or conflicts with program staff were the most commonly endorsed. The severity of participant's symptoms and logistical problems interfering with appointments were less commonly reported as reasons for dropping out. Demographic, substance abuse, and motivational stage indicators were infrequently associated with subjective reasons for dropout. In contrast, indicators of maladaptive personality functioning were strongly associated with many reasons for dropping out, especially concerns about privacy and boundary issues within the program. Results from this preliminary evaluation will guide the development of an instrument and intervention focused on dropout risk factors and treatment reengagement.

This research examined electronic cigarette (e-cigarette) use by individuals in treatment for substance abuse, a population with a high prevalence of tobacco use and poor smoking cessation outcomes. We surveyed 1127 individuals from 24 substance abuse treatment centers across the United States. Bivariate analyses and logistic regression were used to examine factors associated with daily (N = 87) versus weekly (N = 81) e-cigarette use. Among the full sample, 59.8% reported any lifetime use of e-cigarettes, with 23.6% reporting past 30-day use. Daily e-cigarette users were more likely to have used second-generation, tank-type e-cigarettes, χ2(1,N = 165) = 11.54, p = .001, used more flavors overall, t(168) = 2.15, p = .03, and were more likely to report using their e-cigarette continuously throughout the day, χ2(4,N = 168) = 16.7, p = .002, compared to weekly e-cigarette users. Over half (57.7%) of the daily and weekly e-cigarette users reported having an e-cigarette device that broke. The logistic regression model adjusting for clinic type and days with poor mental health found that daily e-cigarette users were significantly more likely than weekly e-cigarette users to be from methadone clinics (adjusted odds ratio [AOR] = 2.40, p = .04), and former smokers (AOR = 6.37, p users in substance abuse treatment were more likely to be from methadone clinics and former cigarette smokers. However, the majority (73.6%) of daily e-cigarette users were current cigarette smokers. E-cigarette device type reliability (eg, breakage) may be an important factor to consider among drug treatment and other populations with lower socioeconomic status. This study found several differences in the device type, flavors, and use characteristics of daily versus weekly e-cigarette users. While majority of e-cigarette users in substance abuse treatment were current cigarette smokers, daily e-cigarette users were more likely to be former cigarette smokers.

"Who can you tell?" Features of Arab culture that influence conceptualization and treatment of childhood sexual abuse.

Science.gov (United States)

Haboush, Karen L; Alyan, Hala

2013-01-01

The literature on child sexual abuse reflects growing recognition of the manner in which culture impacts the conceptualization, experience, and treatment of such cases. Despite heightened visibility of Arab Americans within the United States, population due to recent media attention, little empirical research exists on the occurrence of child sexual abuse within this population. Arab culture is often characterized by an emphasis on collectivism and familial obligations, and such features may prove to either facilitate or impede assessment and treatment of child sexual abuse, depending on how they are manifested. In terms of reporting child sexual abuse, cultural values pertaining to shame and honor as well as the stigma attached to mental health problems may influence the response to abuse. As such, enhancing the cultural competence of the therapist is key to facilitating effective cultural practice. Empirical research is required to investigate and substantiate these concepts as they relate to child sexual abuse in Arab-American populations.

Despite strong interest in improving collaborations between correctional and substance abuse treatment organizations, there is a lack of empirical data describing the existing practices. The current study used a national survey of correctional administrators to examine organizational factors related to cross-agency collaboration and integration activities between corrections and substance abuse treatment organizations. Using a measure of collaboration that scaled cross-agency activities from less structured, informal networking and coordination to more structured and formalized levels of cooperation and collaboration, we found that different correctional settings (e.g., community corrections, jails, prisons) differed significantly in terms of their collaborative activities with substance abuse treatment agencies. We also found that the organizational characteristics that were associated with different levels of collaboration and integration differed across the correctional settings. Further research is needed to better understand how and why correctional agencies decide to formalize collaborative arrangements with treatment agencies and whether these efforts lead to more favorable outcomes.

2015-07-01

Methylphenidate, an amphetamine-like prescription medication for attention deficit hyperactivity disorder (ADHD) was suspected as being abused among methadone maintenance treatment (MMT) patients. We tested its presence in the routine urine monitoring of all patients in both Tel Aviv and Las Vegas MMT clinics. Data on demographic and addiction history, ADHD (Wender Utah Rating Scale), cognitive impairment (Mini Mental State Exam), and lifetime DSM-IV-TR psychiatric diagnosis from admission were retrieved, and retention following 6 months. None of the 190 patients in Las Vegas tested positive for methylphenidate, while 14.7% (45/306) did in Tel Aviv. Abusers were less educated (p = 0.01), had higher ADHD scores (p = 0.02), lower cognitive scores (p = 0.05), and a higher benzodiazepine (BDZ) abuse rate (p cannabis, opiates, and cocaine abuse and infectious disease. Of the methylphenidate abuse 42.2% have take-home methadone dose privileges. Not like opiate use, being methylphenidate positive did not relate to 6-months retention. Compared to Tel Aviv, Las Vegas patients were more educated, with lower BDZ, and cocaine abuse. The greater abuse of methylphenidate among ADHD subjects might indicate their using it as self-medication, raising a possible indication for its prescription for that subgroup of MMT patients. The high rate of methylphenidate abuse in Israel needs future study. Copyright © 2015 Elsevier Inc. All rights reserved.

Today's CubeSats mostly operate their communications at UHF- and S-band frequencies. UHF band is presently crowded, thus downlink communications are at lower data rates due to bandwidth limitations and are unreliable due to interference. This research presents an end-to-end robust, innovative, compact, efficient and low cost S-band uplink and X-band downlink CubeSat communication system demonstration between a balloon and a Near Earth Network (NEN) ground system. Since communication systems serve as umbilical cords for space missions, demonstration of this X-band communication system is critical for successfully supporting current and future CubeSat communication needs. This research has three main objectives. The first objective is to design, simulate, and test a CubeSat S- and X-band communication system. Satellite Tool Kit (STK) dynamic link budget calculations and HFSS Simulations and modeling results have been used to trade the merit of various designs for small satellite applications. S- and X-band antennas have been tested in the compact antenna test range at Goddard Space Flight Center (GSFC) to gather radiation pattern data. The second objective is simulate and test a CubeSat compatible X-band communication system at 12.5Mbps including S-band antennas, X-band antennas, Laboratory for Atmospheric and Space Physics (LASP) /GSFC transmitter and an S-band receiver from TRL-5 to TRL-8 by the end of this effort. Different X-band communication system components (antennas, diplexers, etc.) from GSFC, other NASA centers, universities, and private companies have been investigated and traded, and a complete component list for the communication system baseline has been developed by performing analytical and numerical analysis. This objective also includes running simulations and performing trades between different X-band antenna systems to optimize communication system performance. The final objective is to perform an end-to-end X-band CubeSat communication system

Cohn, Amy; Najavits, Lisa M

2014-04-01

Victimization by and perpetration of domestic violence are associated with co-occurring mental and substance use disorders. This study used data from the National Survey of Substance Abuse Treatment Services to examine differences in organizational factors, treatment approaches offered, and client-level factors among 13,342 substance abuse treatment facilities by whether or not they offered domestic violence services. Only 36% of the facilities offered domestic violence services. Those that offered such services were more likely than those that did not to treat clients with co-occurring disorders. Principal-components analysis reduced eight treatment approaches to two factors: psychosocial services and traditional substance abuse services. Regression models indicated that the frequency with which psychosocial services were offered depended on the percentage of clients with co-occurring disorders who were being treated in the facility and whether or not that facility offered domestic violence services. Specifically, facilities that did not offer domestic violence services and that had a high percentage of clients with co-occurring disorders were more likely to offer psychosocial services than facilities that offered domestic violence services. A larger proportion of facilities offering domestic violence services offered traditional substance abuse treatment services, compared with facilities not offering domestic violence services, but this relationship was not contingent on the percentage of clients with co-occurring disorders at each facility. Improved efforts should be made to tailor treatments to accommodate the links between domestic violence, mental disorders, and substance abuse.

Substance abuse treatment following a natural disaster is often met with challenges. If treatment is available, facilities may be unequipped to service an influx of patients or provide specialized care for unique populations. This paper seeks to evaluate trends in substance abuse treatment over time and assess changes pre- and post-Hurricane Katrina. Substance abuse treatment admission data (N = 42,678) from New Orleans, Louisiana, for years 2000 through 2012 were obtained from the Treatment Episode Data Set. Admissions were examined to evaluate demographic, socioeconomic, psychiatric, and criminality trends in substance abuse treatment and assess changes following Hurricane Katrina. Treatment admissions have decreased from 2000 to 2012. About one in five admissions had a psychiatric illness in addition to a substance abuse problem. A staggering 76% of admissions with a psychiatric illness were referred by the criminal justice system post-Katrina as compared to pre-Katrina. Rates of alcohol and marijuana admissions have remained stable from 2000 to 2012. Cocaine/crack admissions have declined and admissions who abused heroin have increased over time. Treatment admissions stabilized following Hurricane Katrina; however, since 2009, they have begun to decline. Targeted exploration of factors affecting admission to treatment in New Orleans with populations such as the homeless, those with a psychiatric illness in addition to a substance abuse problem, and those referred by the criminal justice system is essential. The results of this study assist in identifying variations in substance abuse treatment characteristics for those admitted to treatment in New Orleans.

The selection of tasks for analysis is made based on the decision tree that incorporates management's expectations of task difficulty and importance. The training setting (e.g., OJT, classroom, simulator, or laboratory) and the steps necessary to prepare the final training plan (along with example training plans for RO/SRO) was presented. The On-the-Job Training Manual is composed of a special video of each system that guides the trainee through a specified route in the plant showing the keypoints about the specific system. This Manual includes scanned photos of the main components and very detailed layout drawings to quickly walk-through a system. Two data bases were established to keep track of all the systems and tasks associated with a job post and to maintain the JPMs. SAT application in Spain, Argentina, Novovoronezh (Russia), and Hungary has varied by the time and human resources necessary to develop a complete SAT or a simplified SAT (which omits the taxonomic code for obtaining knowledge and skills associated to each task). An example of simulator training program materials and its correlation with the JPMs was presented along with a simulator evaluation guide showing how to assess RO/SRO behaviour

NASA Ames Research Center and the George Washington University have developed an electric propulsion subsystem that can be integrated into the PhoneSat bus. Experimental tests have shown a reliable performance by firing three different thrusters at various frequencies in vacuum conditions. The three thrusters were controlled by a SmartPhone that was running the PhoneSat software. The subsystem is fully operational and it requires low average power to function (about 0.1 W). The interface consists of a microcontroller that sends a trigger pulses to the PPU (Plasma Processing Unit), which is responsible for the thruster operation. Frequencies ranging from 1 to 50Hz have been tested, showing a strong flexibility. A SmartPhone acts as the main user interface for the selection of commands that control the entire system. The micro cathode arc thruster MicroCAT provides a high 1(sub sp) of 3000s that allows a 4kg satellite to obtain a (delta)V of 300m/s. The system mass is only 200g with a total of volume of 200(cu cm). The propellant is based on a solid cylinder made of Titanium, which is the cathode at the same time. This simplicity in the design avoids miniaturization and manufacturing problems. The characteristics of this thruster allow an array of MicroCATs to perform attitude control and orbital correcton maneuvers that will open the door for the implementation of an extensive collection of new mission concepts and space applications for CubeSats. NASA Ames is currently working on the integration of the system to fit the thrusters and PPU inside a 1.5U CubeSat together with the PhoneSat bus into a 1.5U CubeSat. This satellite is intended to be deployed from the ISS in 2015 and test the functionality of the thrusters by spinning the satellite around its long axis and measure the rotational speed with the phone byros.

The 3D Printing the Complete CubeSat project is designed to advance the state-of-the-art in 3D printing for CubeSat applications. Printing in 3D has the potential to increase reliability, reduce design iteration time and provide greater design flexibility in the areas of radiation mitigation, communications, propulsion, and wiring, among others. This project is investigating the possibility of including propulsion systems into the design of printed CubeSat components. One such concept, an embedded micro pulsed plasma thruster (mPPT), could provide auxiliary reaction control propulsion for a spacecraft as a means to desaturate momentum wheels.

Nigeria, the most populous country in Africa and the 8th most populous in the world with a population of over 154 million, does not have current data on substance abuse treatment demand and treatment facilities; however, the country has the highest one-year prevalence rate of Cannabis use (14.3%) in Africa and ranks third in Africa with respect to the one-year prevalence rate of cocaine (0.7%) and Opioids (0.7%) use. This study aimed to determine the types, spread and characteristics of the substance abuse treatment centers in Nigeria. The study was a cross sectional survey of substance abuse treatment centers in Nigeria. Thirty-one units were invited and participated in filling an online questionnaire, adapted from the European Treatment Unit/Program Form (June 1997 version). All the units completed the online questionnaire. A large proportion (48%) was located in the South-West geopolitical zone of the country. Most (58%) were run by Non-Governmental Organizations. Half of them performed internal or external evaluation of treatment process or outcome. There were a total of 1043 for all categories of paid and volunteer staff, with an average of 33 staff per unit. Most of the funding came from charitable donations (30%). No unit provided drug substitution/maintenance therapy. The units had a total residential capacity of 566 beds. New client admissions in the past one year totalled 765 (mean = 48, median = 26.5, min = 0, max = 147) and 2478 clients received services in the non-residential units in the past year. No unit provided syringe exchange services. The study revealed a dearth of substance abuse treatment units (and of funds for the available ones) in a country with a large population size and one of the highest prevalence rates of substance abuse in Africa. The available units were not networked and lacked a directory or an evaluation framework.

This paper introduces the Japan Canada Joint Collaboration Satellites - Formation Flying (JC2Sat-FF) project. JC2Sat-FF is a joint project between the Canadian Space Agency (CSA) and the Japan Aerospace Exploration Agency (JAXA) with the end goal of building, launching and operating two 20kg- class nanosatellites for technical demonstration of formation flight (FF) using differential drag technique, relative navigation using commercial off-the-shelf (COTS) dual band GPS receivers and far infra-red radiance measurement. A unique aspect of this project is that the two JC2Sats are developed by a united small team consisting of engineers and researchers from both agencies. Technical exchange in this international team gives stimulation to the members and generates a synergistic effect for the project.

Women who experience intimate partner violence (IPV) victimization are more likely to struggle with substance abuse problems than are women who do not experience IPV. Given the connection between IPV victimization and substance abuse, recommended practices urge collaboration between domestic violence service agencies and substance abuse treatment agencies to provide comprehensive services for women with these co-occurring problems. However, domestic violence and substance abuse services have unique histories of development that have led to distinct ways of service delivery. To promote successful collaborations, service providers and researchers are developing strategies to foster relationships across the two service sectors. The authors conducted a review of this emerging body of knowledge with the aim of assembling recommendations for strategies to foster collaboration between domestic violence and substance abuse services. The authors identified 15 documents for review inclusion and our analysis established 5 categories of documents. Findings yield key collaboration strategies and recommended service models. In addition, the review determined the existence of considerable challenges to promoting collaborative relationships between domestic violence and substance abuse treatment service sectors.

CubeSat Material Limits for Design for Demise

2014-01-01

The CubeSat form factor of nano-satellite (a satellite with a mass between one and ten kilograms) has grown in popularity due to their ease of construction and low development and launch costs. In particular, their use as student led payload design projects has increased due to the growing number of launch opportunities. CubeSats are often deployed as secondary or tertiary payloads on most US launch vehicles or they may be deployed from the ISS. The focus of this study will be on CubeSats launched from the ISS. From a space safety standpoint, the development and deployment processes for CubeSats differ significantly from that of most satellites. For large satellites, extensive design reviews and documentation are completed, including assessing requirements associated with re-entry survivability. Typical CubeSat missions selected for ISS deployment have a less rigorous review process that may not evaluate aspects beyond overall design feasibility. CubeSat design teams often do not have the resources to ensure their design is compliant with re-entry risk requirements. A study was conducted to examine methods to easily identify the maximum amount of a given material that can be used in the construction of a CubeSats without posing harm to persons on the ground. The results demonstrate that there is not a general equation or relationship that can be used for all materials; instead a limiting value must be defined for each unique material. In addition, the specific limits found for a number of generic materials that have been previously used as benchmarking materials for re-entry survivability analysis tool comparison will be discussed.

Psychostimulant abuse continues to present legal, socioeconomic and medical challenges as a primary psychiatric disorder, and represents a significant comorbid factor in major psychiatric and medical illnesses. To date, monotherapeutic drug treatments have not proven effective in promoting long-term abstinence in psychostimulant abusers. In contrast to clinical trials utilizing monotherapies, combinations of dopamine (DA) agonists and selective 5-HT3, 5HT2A/2C, or NK1 antagonists have shown robust efficacy in reversing behavioral and neurobiological alterations in animal models of psychostimulant abuse. One important temporal requirement for these treatments is that the 5-HT or NK1 receptor antagonist be given at a critical time window after DA agonist administration. This requirement may reflect a necessary dosing regimen towards normalizing underlying dysfunctional neural circuits and “addiction memory” states. Indeed, chronic psychostimulant abuse can be conceptualized as a consolidated form of dysfunctional memory maintained by repeated drug- or cue-induced reactivation of neural circuit and subsequent reconsolidation. According to this concept, the DA agonist given first may reactivate this memory circuit, thereby rendering it transiently labile. The subsequent antagonist is hypothesized to disrupt reconsolidation necessary for restabilization, thus leading progressively to a therapeutically-mediated abolishment of dysfunctional synaptic plasticity. We propose that long-term abstinence in psychostimulant abusers may be achieved not only by targeting putative mechanistic pathways, but also by optimizing drug treatment regimens designed to disrupt the neural processes underlying the addicted state.

Despite the high prevalence and known morbidity and mortality caused by cigarette smoking, 60% to 70% of substance abuse treatment programs lack smoking cessation counseling or fail to offer pharmacotherapy for smoking cessation, including those programs designed to meet the needs of drug-dependent pregnant patients. Previous studies of staff knowledge, attitudes, and practices (S-KAP) at general substance abuse/HIV treatment programs have suggested that staff may contribute to the deficiency in smoking cessation treatment in these settings. It is not known whether similar deficiencies exist at perinatal substance abuse treatment programs. This study compared cigarette S-KAP in perinatal substance abuse (n = 41) and general substance abuse/HIV treatment (Veterans Affairs [VA] medical center, hospital-, and community-based) workforce samples (n = 335). Significant differences were seen between the 2 groups on all measures, but perinatal staff compared favorably to general staff only on measures of barriers to smoking cessation services. Perinatal staff compared unfavorably on all other measures: knowledge, beliefs/attitudes, self-efficacy, and smoking cessation practices. Pair-wise comparisons of knowledge and beliefs/attitudes revealed a significant difference between perinatal and VA staff; of self-efficacy, between perinatal and staff at all other settings; and of smoking cessation practices, between perinatal and VA and community-based staff. These results-showing deficiencies of perinatal staff on most S-KAP measures-are concerning and suggest that identifying gaps in and improving S-KAP in perinatal substance abuse programs is urgently needed, for which the VA may provide an efficacious model.

Contingency management interventions that provide tangible incentives based on objective indicators of drug abstinence have improved treatment outcomes of substance abusers, but have not been widely implemented in community drug abuse treatment settings. To compare outcomes achieved when a lower-cost prize-based contingency management treatment is added to usual care in community methadone hydrochloride maintenance treatment settings. Random assignment to usual care with (n = 198) or without (n = 190) abstinence incentives during a 12-week trial. Six community-based methadone maintenance drug abuse treatment clinics in locations across the United States. Three hundred eighty-eight stimulant-abusing patients enrolled in methadone maintenance programs for at least 1 month and no more than 3 years. Participants submitting stimulant- and alcohol-negative samples earned draws for a chance to win prizes; the number of draws earned increased with continuous abstinence time. Total number of stimulant- and alcohol-negative samples provided, percentage of stimulant- and alcohol-negative samples provided, longest duration of abstinence, retention, and counseling attendance. Submission of stimulant- and alcohol-negative samples was twice as likely for incentive as for usual care group participants (odds ratio, 1.98; 95% confidence interval, 1.42-2.77). Achieving 4 or more, 8 or more, and 12 weeks of continuous abstinence was approximately 3, 9, and 11 times more likely, respectively, for incentive vs usual care participants. Groups did not differ on study retention or counseling attendance. The average cost of prizes was 120 dollars per participant. An abstinence incentive approach that paid 120 dollars in prizes per participant effectively increased stimulant abstinence in community-based methadone maintenance treatment clinics.

Latino Americans report underutilization of treatment and poor treatment response for substance use and abuse compared to other racial/ethnic groups; thus, it is important to assess factors that contribute to these disparities. The current study objective was to assess the influence of family conflict on substance abuse treatment response in a sample of Latino Americans using two different yet complementary analyses. First, ordinary least squares regression was used to assess the association between overall family conflict and pre- and post-treatment substance use. Second, repeated measures latent class analysis was used to identify groups based on family member conflict and timing of conflict during treatment. Findings indicated that family conflict contributed unique variance to concurrent substance use; however pre-treatment family conflict was not related to post-treatment outcomes. Results also identified three distinct family conflict groups: no/low conflict, pre-treatment conflict, and post-treatment conflict who differed in pre- and post-treatment substance use. Post hoc investigation revealed that those who experienced pre-treatment conflict but low post-treatment conflict showed the greatest decrease in substance use. Findings highlight the importance of considering family conflict during all stages of treatment for Latino American substance users. Copyright © 2015 Elsevier Inc. All rights reserved.

Objective To examine factors associated with Medicaid acceptance for substance abuse (SA) services by outpatient SA treatment programs. Data Sources Secondary analysis of 2003–2006 National Survey of Substance Abuse Treatment Services data combined with state Medicaid policy and usage measures and other publicly available data. Study Design We used cross-sectional analyses, including state fixed effects, to assess relationships between SA treatment program Medicaid acceptance and (1) program-level factors, (2) county-level sociodemographics and treatment program density, and (3) state-level population characteristics, SA treatment-related factors, and Medicaid policy and usage. Data Extraction Methods State Medicaid policy data were compiled based on reviews of state Medicaid-related statutes/regulations and Medicaid plans. Other data were publicly available. Principal Findings Medicaid acceptance was significantly higher for programs: (a) that were publicly funded and in states with Medicaid policy allowing SA treatment coverage; (b) with accreditation/licensure and nonprofit/government ownership, as well as mental- and general-health focused programs; and (c) in counties with lower household income. Conclusions SA treatment program Medicaid acceptance related to program-, county, and state-level factors. The data suggest the importance of state policy and licensure/accreditation requirements in increasing SA program Medicaid access. PMID:21105870

Gonzalez, M.

1995-01-01

The NPP engineering support functional area comprises seven common positions: reactor engineer, in-service inspection engineer, performance reliability engineer, system-maintenance engineer, station modification engineer, quality assurance engineer, and regulatory compliance engineer. The primary duties and tasks of each was presented. In Spain, a simplified SAT approach was used to analyze the training needs of these positions. The basic difference between the comprehensive SAT and the simplified method is that the simplified approach uses no taxonomy codes and the task elements are not analyzed to obtain the knowledge and skills. Resulting in an economy of time and personnel resources, this process makes use of job competencies and a top table analysis conducted by subject matter experts. An example of a JPM prepared using the simplified SAT approach was shown. Examples of the simplified approaches used in Russia, France, and USA were also discussed

Miniature scientific-grade magnetic sensors for CubeSats

2016-07-01

Micro- and nanosatellites have become more attractive due to their low development and launch cost. A class of nanosatellites defined by the CubeSat standard allows standardizing CubeSat preparation and launch, thus making the projects more affordable. Because of the complexity of sensors miniaturization to install them onboard CubeSat, the majority of CubeSat launches are aimed the technology demonstration or education missions. The scientific success of CubeSat mission depends on the sensors quality. In spite that the sensitivity of the magnetic sensors strongly depends on their size, the recent development in this branch allows us to propose tiny but sensitive both AC and DC magnetometers. The goal of the present report is to introduce the new design of miniature three-component sensors for measurement of vector magnetic fields - for quasi-stationary and slowly fluctuating - flux-gate magnetometer (FGM) - and for alternative ones - search-coil magnetometer (SCM). In order to create magnetometers with the really highest possible level of parameters, a set of scientific and technological problems, mostly aimed at the sensor construction improvement, was solved. The most important parameter characterizing magnetometer quality is its own magnetic noise level (NL). The analysis of the NL influencing factors is made and the ways to decrease it are discussed in the report. Construction details and technical specifications of miniature but sensitive FGM and SCM for the CubeSat mission are presented. This work is supported by EC Framework 7 funded project 607197.

A novel solid-angle tomosynthesis (SAT) scanning scheme

International Nuclear Information System (INIS)

Zhang Jin; Yu, Cedric

2010-01-01

Purpose: Digital tomosynthesis (DTS) recently gained extensive research interests in both diagnostic and radiation therapy fields. Conventional DTS images are generated by scanning an x-ray source and flat-panel detector pair on opposite sides of an object, with the scanning trajectory on a one-dimensional curve. A novel tomosynthesis method named solid-angle tomosynthesis (SAT) is proposed, where the x-ray source scans on an arbitrary shaped two-dimensional surface. Methods: An iterative algorithm in the form of total variation regulated expectation maximization is developed for SAT image reconstruction. The feasibility and effectiveness of SAT is corroborated by computer simulation studies using three-dimensional (3D) numerical phantoms including a 3D Shepp-Logan phantom and a volumetric CT image set of a human breast. Results: SAT is able to cover more space in Fourier domain more uniformly than conventional DTS. Greater coverage and more isotropy in the frequency domain translate to fewer artifacts and more accurately restored features in the in-plane reconstruction. Conclusions: Comparing with conventional DTS, SAT allows cone-shaped x-ray beams to project from more solid angles, thus provides more coverage in the spatial-frequency domain, resulting in better quality of reconstructed image.

Ogle, Richard L; Baer, John S

2003-11-01

Two personalized substance abuse assessment and feedback interventions were tested for effectiveness in engaging female domestic violence shelter residents in substance abuse treatment. One hundred forty-seven residents were assessed for quantity andfrequency of substance use, negative consequences due to use, motivation to change substance use behavior, and psychopathological symptoms related to substance abuse. Assessment identified (33) 22% of participants as heavy substance users. Twenty of the 33 heavy-using residents received one of two personalized substance use feedback interventions:face-to-face feedback or writtenfeedbackplaced in shelter mailboxes. Treatment engagement was defined as attending at least one substance abuse treatment session within 30 days after the intervention. Results showed a significant difference in treatment engagement rates in favor of the face-to-face feedback group (60% vs. 0%). The results provide preliminary data suggesting that substance abuse assessment can be effectively accomplished in the shelter environment and that the face-to-face feedback procedure may be an effective intervention to bridge the service linkage problem between domestic violence services and substance abuse treatment.

Cigarette smoking is common among patients in substance abuse treatment. Tobacco control programs have advocated for integrated tobacco dependence treatment into behavioral healthcare, including within substance abuse treatment facilities (SATFs) to reduce the public health burden of tobacco use. This study used data from seven waves (2006 to 2012) of the National Survey of Substance Abuse Treatment Services (n=94,145) to examine state and annual changes in the provision of smoking cessation services within US SATFs and whether changes over time could be explained by facility-level (private vs public ownership, receipt of earmarks, facility admissions, acceptance of government insurance) and state-level factors (cigarette tax per pack, smoke free policies, and percent of CDC recommended tobacco prevention spending). Results showed that the prevalence of SATFs offering smoking cessation services increased over time, from 13% to 65%. The amount of tax per cigarette pack, accepting government insurance, government (vs private) ownership, facility admissions, and CDC recommended tobacco prevention spending (per state) were the strongest correlates of the provision of smoking cessation programs in SATFs. Facilities that received earmarks were less likely to provide cessation services. Adult smoking prevalence and state-level smoke free policies were not significant correlates of the provision of smoking cessation services over time. Policies aimed at increasing the distribution of tax revenues to cessation services in SATFs may offset tobacco-related burden among those with substance abuse problems. Copyright © 2017.

Elder abuse is an increasingly important issue that must be addressed in a systematic and coordinated way. Our objective was to evaluate the perceived feasibility of establishing an elder abuse care program at hospital-based sexual assault and domestic violence treatment centers in Ontario, Canada. In July 2012, a questionnaire focused on elder abuse care was distributed to all of Ontario's Sexual Assault/Domestic Violence Treatment Centre (SA/DVTC) Program Coordinators/Managers. We found that the majority of Program Coordinators/ Managers favored expansion of their program mandates to include an elder abuse care program. However, these respondents viewed collaboration with a large network of well trained professionals and available services in the community that address elder abuse as integral to responding in a coordinated manner. The expansion of health services to address the needs of abused older adults in a comprehensive and integrated manner should be considered as an important next step for hospital-based violence care programs worldwide.

Propp, A. M.; Benmergui, J. S.; Turner, A. J.; Wofsy, S. C.

2017-12-01

In this study, we investigate the new information that will be provided by MethaneSat, a proposed satellite that will measure the total column dry-air mole fraction of methane at 1x1 km or 2x2 km spatial resolution with 0.1-0.2% random error. We run an atmospheric model to simulate MethaneSat's ability to characterize methane emissions from the Barnett Shale, a natural gas province in Texas. For comparison, we perform observation system simulation experiments (OSSEs) for MethaneSat, the National Oceanic and Atmospheric administration (NOAA) surface and aircraft network, and Greenhouse Gases Observing Satellite (GOSAT). The results demonstrate the added benefit that MethaneSat would provide in our efforts to monitor and report methane emissions. We find that MethaneSat successfully quantifies total methane emissions in the region, as well as their spatial distribution and steep gradients. Under the same test conditions, both the NOAA network and GOSAT fail to capture this information. Furthermore, we find that the results for MethaneSat depend far less on the prior emission estimate than do those for the other observing systems, demonstrating the benefit of high sampling density. The results suggest that MethaneSat would be an incredibly useful tool for obtaining detailed methane emission information from oil and gas provinces around the world.

Sex-specific substance abuse treatment for female healthcare professionals: implications.

Koos, Erin; Brand, Michael; Rojas, Julio; Li, Ji

2014-01-01

Gender plays a significant role in the development and treatment of substance abuse disorders. Sex-specific treatment for girls and women has recurrently proven more effective, with better outcomes than traditional treatment. Research on impaired healthcare professionals (HCPs) has largely focused on men, garnering little attention for women and sex differences. With the increasing numbers of female HCPs, it is imperative to identify potential sex differences that may have implications for treatment. Our study compared a convenience sample of male and female HCPs with substance abuse disorders treated in an outpatient program to identify sex differences that may have implications for treatment. Our sample consisted of 96 HCPs (54 men, 42 women) and 17 non-healthcare professional (N-HCP) women. All of the participants were evaluated using the program's clinical interview and the Personality Assessment Inventory (PAI). Chart review data contained categorical variables, qualitative variables, diagnoses, and psychological test scores. A second analysis was conducted through two separate comparisons: the PAI results of comparing impaired female HCPs with impaired male HCPs and the PAI results of comparing impaired female HCPs with impaired female N-HCPs. Statistically significant differences indicated more male participants received prior treatment and more intensive treatment than female participants. More female subjects reported being diagnosed as having a comorbid psychiatric condition and taking psychotropic medications. Several statistically significant differences in the PAI scores were found. Among female HCPs, elevations were found in anxiety, depression, paranoia, and borderline personality disorder. Substantive differences, although not statistically significant, were elevations in somatic complaints and anxiety disorders in female HCPs. In the comparison of female HCPs and N-HCPs, the only statistically significant difference was the significantly higher

Although studies on the initiation of substance abuse abound, the body of literature on prescription opioid abuse (POA) etiology is small. Little is known about why and how the onset of POA occurs, especially among high-risk populations. In this study we aimed to fill this important knowledge gap by exploring the POA initiation experiences of 90 prescription opioid abusers currently in treatment and their narrative accounts of the circumstances surrounding their POA onset. This research was conducted within a storyline framework, which operates on the premise that the path to drug abuse represents a biography or a process rather than a static condition. Audiotapes of in-depth interviews were transcribed, coded, and thematically analyzed. Analyses revealed the presence of four trajectories leading to POA. This study adds to the limited research on POA etiology by not only illuminating the psychosocial factors that contribute to POA onset, but also by situating initiation experiences within broader life processes. The study findings provide crucial insights to policymakers and interventionists in identifying who is at risk for POA, and more important, when and how to intervene most efficaciously.

In the US, the spiraling costs of substance abuse and mental health treatment caused many state Medicaid agencies to adopt managed behavioral health care (MBHC) plans during the 1990s. Although research suggests that these plans have successfully reduced public sector spending, their impact on the quality of substance abuse treatment has not been established. The Massachusetts Medicaid program started a risk-sharing contract with MHMA, a private, for-profit specialty managed behavioral health care (MBHC) carve-out vendor on July 1, 1992. This paper evaluates the carve-out s impact on spending per inpatient episode and three proxy measures of quality: (i) access to inpatient treatment (ii) 30-day re-admissions and (iii) continuity of care. Medicaid claims for inpatient treatment were collapsed into episodes. Clients were tracked across the five-year period and an interrupted time series design was used to compare the three quality outcomes and spending in the year prior to (FY1992) and the four years during MHMA (FY1993-FY1996). Logistic and linear regression models were used to control for race, disability status, age, gender and primary diagnosis. Despite a 99% reduction in the use of hospital-based settings, access to 24-hour services overall increased by 38%, largely due to an expansion in the use of freestanding detoxification and acute residential services. Continuity improved by 73%. Nevertheless, rates of 7-day (58%) and 30-day (24%) readmission increased significantly, even after controlling for increases in disability status. Per episode spending decreased by 76% ($2,773), characterized by a dramatic spending reduction in FY1993 that was maintained but not augmented in subsequent years. The carve-out had mixed effects on the quality of substance abuse treatment. While one of the three measures (readmission rates) deteriorated, two improved (access and continuity). Rapid re-admissions were strongly associated with shorter lengths of stay, suggesting that

Synergy between ground-based and satellite radar observations of clouds and precipitation is important for refining the algorithms to retrieve hydrometeor microphysical parameters, improvements in the retrieval accuracy, and better understanding the advantages and limitations of different retrieval approaches. The new dual-frequency (Ka- and W-band, 35 GHz and 94 GHz) fully polarimetric scanning U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Research Facility cloud radars (SACRs-2) are advanced sensors aimed to significantly enhance remote sensing capabilities (Kollias et al. 2016). One of these radars was deployed as part of the third ARM Mobile Facility (AMF3) at Oliktok Point, Alaska (70.495o N, 149.886oW). The National Aeronautics and Space Administration (NASA) CloudSat satellite, which is part of the polar-orbiting A-train satellite constellation, passes over the vicinity of the AMF3 location (typically within 0-7 km depending on a particular overpass) on a descending orbit every 16 days at approximately 13:21 UTC. The nadir pointing W-band CloudSat cloud profiling radar (CPR) provides vertical profiles of reflectivity that are then used for retrievals of hydrometeor parameters (Tanelli et al. 2008). The main objective of the AMF3 CloudSat overpasses intensive operating period (IOP) campaign was to collect approximately collocated in space and time radar data from the SACR-2 and the CloudSat CPR measurements for subsequent joint analysis of radar variables and microphysical retrievals of cloud and precipitation parameters. Providing the reference for the SACR-2 absolute calibration from the well-calibrated CloudSat CPR was another objective of this IOP. The IOP objectives were achieved by conducting seven special SACR-2 scans during the 10.5-min period centered at the exact time of the CloudSat overpass over the AMF3 (~1321 UTC) on six dates of the CloudSat overpasses during the three-month period allocated to this IOP. These six days

Spaceflight crews will be exposed to levels of radiation which exceed those experienced on the ground. In order to reduce the uncertainty in the evaluation of risks it is necessary to validate the responses of biological systems in space under conditions which simulate exposure levels expected during exploration class missions. The LifeSat system provides the experimental capabilities to satisfy these goals. Specifically, LifeSat is capable of long duration flights of up to 60 days, is able to fly directly into trapped radiation belts and in circular or eccentric polar orbits, has the ability to provide artificial gravity and imposes fewer restrictions than the STS on the use of hazardous materials such as chemical fixatives. These features along with reference missions and experiments are discussed with respect to radiation research goals

CloudSat Education Network (CEN): Partnerships to improve the understanding of clouds in formal and informal settings. Since The CloudSat satellite launched in 2006 the Formal and Informal education programs for the mission have been focused on bringing an understanding about the mission science and the importance of clouds, climate & weather science. This has been done by creating and strengthening partnership and collaboration within scientific and educational communities around the country and the world. Because CloudSat was formally recognized as a Earth System Science Pathfinder campaign with the GLOBE program, the CEN developed a set of field protocols for student observations that augmented the GLOBE atmosphere protocols when there was a satellite overpass. This shared process between GLOBE & CloudSat resulted in the training & creation of CEN schools that are both GLOBE schools and CloudSat schools, and also produced three GLOBE partnerships that specialize in cloud science education and outreach. In addition, the CEN has developed productive relationships with other NASA missions and EPO teams. Specifically, in collaboration with the NASA CERES mission projects S'Cool and MyNASAData, we have co-presented at NSTA conferences and with schools participating in a NASA EPOESS-funded formal education project. This collaborative work has been a very real benefit to a wide variety of audiences needing to strengthen their understanding of clouds and their roles in the earth system, and we hope will serve as a model to future missions looking to involve the public in mission science.

This study evaluated a novel drug abuse treatment, the Therapeutic Workplace. In this treatment, patients are paid to perform jobs or to participate in job training. Salary is linked to abstinence by requiring patients to provide drug-free urine samples to gain access to the workplace. Pregnant and postpartum drug abuse patients (N = 40) were randomly assigned to a Therapeutic Workplace or usual care control group. Therapeutic Workplace participants were invited to work 3 hr every weekday for 6 months and could earn up to $4,030 in vouchers for abstinence, workplace attendance, and performance. On average, 45% of participants attended the workplace per day. Relative to controls, the Therapeutic Workplace nearly doubled patients' abstinence from opiates and cocaine (33% vs. 59% of thrice-weekly urine samples drug negative, respectively, p Workplace can effectively treat heroin and cocaine abuse in pregnant and postpartum women.

Using Additive Manufacturing to Print a CubeSat Propulsion System

CubeSats are increasingly being utilized for missions traditionally ascribed to larger satellites CubeSat unit (1U) defined as 10 cm x 10 cm x 11 cm. Have been built up to 6U sizes. CubeSats are typically built up from commercially available off-the-shelf components, but have limited capabilities. By using additive manufacturing, mission specific capabilities (such as propulsion), can be built into a system. This effort is part of STMD Small Satellite program Printing the Complete CubeSat. Interest in propulsion concepts for CubeSats is rapidly gaining interest-Numerous concepts exist for CubeSat scale propulsion concepts. The focus of this effort is how to incorporate into structure using additive manufacturing. End-use of propulsion system dictates which type of system to develop-Pulse-mode RCS would require different system than a delta-V orbital maneuvering system. Team chose an RCS system based on available propulsion systems and feasibility of printing using a materials extrusion process. Initially investigated a cold-gas propulsion system for RCS applications-Materials extrusion process did not permit adequate sealing of part to make this a functional approach.

The knowledge of foot-and-mouth disease virus (FMDV) dynamics and epidemiology in Nigeria and the West Africa subregion is important to support local and regional control plans and international risk assessment. Foot-and-mouth disease virus serotype South African territories (SAT)1 was isolated, identified and characterized from an FMD outbreak in cattle in Nigeria in 2015, 35 years after the last report of FMDV SAT1 in West Africa. The VP1 coding sequence of the Nigerian 2015 SAT1 isolates diverges from reported SAT1 topotypes resulting in a separate topotype. The reporting of a novel FMDV SAT1 strain in the virus pool 5 (West and Central Africa) highlights the dynamic and complex nature of FMDV in this region of Africa. Sustained surveillance is needed to understand the origin, the extent and distribution of this novel SAT1 topotype in the region as well as to detect and monitor the occurrence of (re-)emerging FMDV strains. © 2017 Blackwell Verlag GmbH.

How Serious of a Problem is Staff Turnover in Substance Abuse Treatment? A Longitudinal Study of Actual Turnover1

Science.gov (United States)

Eby, Lillian T.; Burk, Hannah; Maher, Charleen P.

2010-01-01

In the substance abuse treatment field, the annual turnover rate is cited as being anywhere between 19 and 50 percent (Johnson & Roman, 2002; Gallon, Gabriel, & Knudsen, 2003; Knudsen et al., 2003; McLellan et al., 2003). However, no research to date has evaluated these claims by tracking turnover longitudinally using organizational turnover data from substance abuse treatment centers. This research presents the results of a longitudinal study designed to systematically examine actual turnover among counselors and clinical supervisors. Twenty-seven geographically dispersed treatment organizations, serving a wide range of clients in the public and private sector, provided data for the study over a two year time span (2008–2009). The annual turnover rate was 33.2% for counselors and 23.4% for clinical supervisors. For both groups the majority of turnover was voluntary (employee-initiated). Specific reasons for turnover were largely consistent across the two groups, with the most common reason being a new job or new opportunity. The findings are discussed in terms of the unique employment context of substance abuse treatment. Practical recommendations are also discussed to help stem the tide of turnover in the field of substance abuse treatment. PMID:20675097

Substance Abuse-Specific Knowledge Transfer or Loss? Treatment Program Turnover versus Professional Turnover among Substance Abuse Clinicians

2014-01-01

This longitudinal study investigated the extent to which substance abuse (SA) clinician turnover is associated with SA-specific knowledge loss due to change in professions (professional turnover) versus SA-specific knowledge transfer due to movement from one SA clinical setting to another (treatment program turnover). For this study, clinicians had to voluntarily leave their current treatment program. Eligible clinicians completed a quantitative survey while employed and a qualitative post-employment exit interview 1 year later. Compared to those that exited the SA profession (N = 99), clinicians who changed treatment programs (N = 120) had greater SA-specific formal knowledge and were more likely to be personally in recovery. No differences were found between the two groups in terms of SA-specific practical knowledge. PMID:25115318

On the verge of an astronomy CubeSat revolution

Shkolnik, Evgenya L.

CubeSats are small satellites built in standard sizes and form factors, which have been growing in popularity but have thus far been largely ignored within the field of astronomy. When deployed as space-based telescopes, they enable science experiments not possible with existing or planned large space missions, filling several key gaps in astronomical research. Unlike expensive and highly sought after space telescopes such as the Hubble Space Telescope, whose time must be shared among many instruments and science programs, CubeSats can monitor sources for weeks or months at time, and at wavelengths not accessible from the ground such as the ultraviolet, far-infrared and low-frequency radio. Science cases for CubeSats being developed now include a wide variety of astrophysical experiments, including exoplanets, stars, black holes and radio transients. Achieving high-impact astronomical research with CubeSats is becoming increasingly feasible with advances in technologies such as precision pointing, compact sensitive detectors and the miniaturization of propulsion systems. CubeSats may also pair with the large space- and ground-based telescopes to provide complementary data to better explain the physical processes observed.

Liu, Kunqi; Zhang, Jingmin; Liu, Gang; Kang, Lishan

Satisfiability (SAT) problem is an NP-complete problem. Based on the analysis about it, SAT problem is translated equally into an optimization problem on the minimum of objective function. A hybrid differential evolution algorithm is proposed to solve the Satisfiability problem. It makes full use of strong local search capacity of hill-climbing algorithm and strong global search capability of differential evolution algorithm, which makes up their disadvantages, improves the efficiency of algorithm and avoids the stagnation phenomenon. The experiment results show that the hybrid algorithm is efficient in solving SAT problem.

Satellite monitoring of visible emissions at night has been established as a useful capability for environmental monitoring and mapping the global human footprint. Pioneering work using Defense Meteorological Support Program (DMSP) sensors has been followed by new work using the more capable Visible Infrared Imaging Radiometer Suite (VIIRS). Beginning in 2014, we have been investigating the ability of small visible light cameras on CubeSats to contribute to nighttime Earth science studies via point-and-stare imaging. This paper summarizes our recent research using a common suite of simple visible cameras on several AeroCube satellites to carry out nighttime observations of urban areas and natural gas flares, nighttime weather (including lighting), and fishing fleet lights. Example results include: urban image examples, the utility of color imagery, urban lighting change detection, and multi-frame sequences imaging nighttime weather and large ocean areas with extensive fishing vessel lights. Our results show the potential for CubeSat sensors to improve monitoring of urban growth, light pollution, energy usage, the urban-wildland interface, the improvement of electrical power grids in developing countries, light-induced fisheries, and oil industry flare activity. In addition to orbital results, the nighttime imaging capabilities of new CubeSat sensors scheduled for launch in October 2017 are discussed.

The overview of the Systematic Approach to Training (SAT) was presented, with particular emphasis given to the applied model (versus the theoretical model) and to the involvement of plant management. Discussion included the benefits and advantages of applied SAT compared to the conventional approach, (which likely was not systematic in nature). For example, formal structured on-the-job training (OJT) was compared to the traditional ''Come, I show you'' form of OJT. Each of the five phases of SAT - analysis, design, development, implementation, and evaluation - was presented and with a focus on two aspects of SAT. First, SAT is a dynamic continuous not discrete model; and second, two phases are critical to the overall success of SAT implementation - analysis (especially needs analysis) and evaluation (especially feedback). These two phases are absolutely essential to ensure the ''self-correcting'' attribute of the SAT model. Finally, examples of problems that could occur if the SAT model fails or weakens; for instance, if OJT becomes unstructured, or if training materials are not kept current

Assessment and Treatment of Abuse Risk in Opioid Prescribing for Chronic Pain

Directory of Open Access Journals (Sweden)

Robert N. Jamison

2011-01-01

Full Text Available Opioid analgesics provide effective treatment for noncancer pain, but many physicians have concerns about adverse effects, tolerance, and addiction. Misuse of opioids is prominent in patients with chronic back pain and early recognition of misuse risk could help physicians offer adequate patient care while implementing appropriate levels of monitoring to reduce aberrant drug-related behaviors. In this review, we discuss opioid abuse and misuse issues that often arise in the treatment of patients with chronic back pain and present an overview of assessment and treatment strategies that can be effective in improving compliance with the use of prescription opioids for pain. Many persons with chronic back pain have significant medical, psychiatric and substance use comorbidities that affect treatment decisions and a comprehensive evaluation that includes a detailed history, physical, and mental health evaluation is essential. Although there is no “gold standard” for opioid misuse risk assessment, several validated measures have been shown to be useful. Controlled substance agreements, regular urine drug screens, and interventions such as motivational counseling have been shown to help improve patient compliance with opioids and to minimize aberrant drug-related behavior. Finally, we discuss the future of abuse-deterrent opioids and other potential strategies for back pain management.

Johnson, Michael

2015-04-01

iCubeSat, the Interplanetary CubeSat Workshop, is an annual technical workshop for researchers working on an exciting new standardised platform and opportunity for planetary and space scientists. The first workshop was held in 2012 at MIT, 2013 at Cornell, 2014 at Caltech with the 2015 workshop scheduled to take place on the 26-27th May 2015 at Imperial College London. Mission concepts and flight projects presented since 2012 have included orbiters and landers targeting asteroids, the moon, Mars, Venus, Saturn and their satellites to perform science traditionally reserved for flagship missions at a fraction of their cost. Some of the first missions proposed are currently being readied for flight in Europe, taking advantage of multiple ride share launch opportunities and technology providers. A review of these and other interplanetary CubeSat projects will be presented, covering details of their science objectives, instrument capabilities, technology, team composition, budget, funding sources, and the other programattic elements required to implement this potentially revolutionary new class of mission.

A hybrid bit-encoding for SAT planning based on clique-partitioning

Science.gov (United States)

Tapia, Cristóbal; San Segundo, Pablo; Galán, Ramón

2017-09-01

Planning as satisfiability is one of the most efficient ways to solve classic automated planning problems. In SAT planning, the encoding used to convert the problem to a SAT formula is critical for the performance of the SAT solver. This paper presents a novel bit-encoding that reduces the number of bits required to represent actions in a SAT-based automated planning problem. To obtain such encoding we first build a conflict graph, which represents incompatibilities of pairs of actions, and bitwise encode the subsets of actions determined by a clique partition. This reduces the number of Boolean variables and clauses of the SAT encoding, while preserving the possibility of parallel execution of compatible (non-neighbor) actions. The article also describes an appropriate algorithm for selecting the clique partition for this application and compares the new encodings obtained over some standard planning problems.

The role of culture in substance abuse treatment programs for American Indian and Alaska Native communities.

Science.gov (United States)

Legha, Rupinder Kaur; Novins, Douglas

2012-07-01

Culture figures prominently in discussions regarding the etiology of alcohol and substance abuse in American Indian and Alaska Native (AI/AN) communities, and a substantial body of literature suggests that it is critical to developing meaningful treatment interventions. However, no study has characterized how programs integrate culture into their services. Furthermore, reports regarding the associated challenges are limited. Twenty key informant interviews with administrators and 15 focus groups with clinicians were conducted in 18 alcohol and substance abuse treatment programs serving AI/AN communities. Transcripts were coded to identify relevant themes. Substance abuse treatment programs for AI/AN communities are integrating culture into their services in two discrete ways: by implementing specific cultural practices and by adapting Western treatment models. More important, however, are the fundamental principles that shape these programs and their interactions with the people and communities they serve. These foundational beliefs and values, defined in this study as the core cultural constructs that validate and incorporate AI/AN experience and world view, include an emphasis on community and family, meaningful relationships with and respect for clients, a homelike atmosphere within the program setting, and an “open door” policy for clients. The primary challenges for integrating these cultural practices include AI/AN communities' cultural diversity and limited socioeconomic resources to design and implement these practices. The prominence of foundational beliefs and values is striking and suggests a broader definition of culture when designing services. This definition of foundational beliefs and values should help other diverse communities culturally adapt their substance abuse interventions in more meaningful ways.

Choi, Sam; Adams, Susie M; MacMaster, Samuel A; Seiters, John

2013-01-01

A significant number of individuals with co-occurring substance abuse and mental health disorders do not engage, stay, and/or complete residential treatment. The purpose of this study is to identify factors during the initial phase of treatment which predict retention in private residential treatment for individuals with co-occurring substance use and mental health disorders. The participants were 1,317 individuals with co-occurring substance abuse and mental health disorders receiving treatment at three residential treatment centers located in Memphis, TN, Malibu, CA, and Palm Springs, CA. Bivariate analysis and logistic regression were utilized to identify factors that predict treatment retention at 30 days. The findings indicate a variety of factors including age, gender, types of drug, Addiction Severity Index Medical and Psychiatric scores, and readiness to change. These identified factors could be incorporated into pretreatment assessments, so that programs can initiate preventive measures to decrease attrition and improve treatment outcomes.

This study had two aims. First, to examine female substance abusers' perceptions regarding factors that contribute to their retention (and therefore positive treatment outcomes in a women-only therapeutic community in Northern Israel. Second, to explore pretreatment internal and external factors including demographic, personal and environmental factors, factors associated with substance use and with the treatment process, and networks of support that contribute to retention and abstinence.Methods: The study was a conducted using a mixed methods approach. Semi-structured qualitative interviews examining perceptions towards treatment were conducted in five focus groups (n = 5 per group; total n = 25. Intake assessments and a battery of questionnaires examining pretreatment internal and external factors related to treatment retention and abstinence were collected from 42 women who were treated in the program during the 2 year study period. Twenty-three women who completed the 12 month program were compared to the 19 women who did not, using chi-square for categorical variables and t-tests for continuous variables. Nineteen of the 23 women who completed the questionnaires also completed a post-treatment follow-up questionnaire.Results: A content analysis of the interviews revealed five central themes: factors associated with treatment entry; impact of treatment in a women-only setting; significant aspects of treatment; difficulties with the setting; prospects for the future

Jogerst, Gerald J; Daly, Jeanette M; Galloway, Lara J; Zheng, Shimin; Xu, Yinghui

2012-01-01

Substance abuse by either victim or perpetrator has long been associated with violence and abuse. Sparse research is available regarding elder abuse and its association with substance abuse. The objective of this study was to evaluate the association of state-reported domestic elder abuse with regional levels of substance abuse. Census demographic and elder abuse data were sorted into substate regions to align with the substance use treatment-planning regions for 2269 US counties. From the 2269 US counties there were 229 substate regions in which there were 213,444 investigations of abuse. For the other Ns (reports and substantiations) there were fewer counties and regions. See first sentence of data analyses and first sentence of results. Elder abuse report rates ranged from .03 to .41% (80 regions), investigation rates .001 to .34% (229 regions), and substantiation rates 0 to .22% (184 regions). Elder abuse investigations and substantiations were associated with various forms of substance abuse. Higher investigation rates were significantly associated with a higher rate of any illicit drug use in the past month, a lower median household income, lower proportion of the population graduated high school, and higher population of Hispanics. Higher substantiation rates were significantly associated with higher rate of illicit drug use in the past month and higher population of Hispanics. It may be worthwhile for administrators of violence programs to pay particular attention to substance abuse among their clients and in their community's environment, especially if older persons are involved. Measures of documented elder abuse at the county level are minimal. To be able to associate substance abuse with elder abuse is a significant finding, realizing that the substance abuse can be by the victim or the perpetrator of elder abuse.

Full Text Available The research aimed to investigate the opinion of professionals in law and health areas on the profile of the sexual abuser of children within the family and the effectiveness of the type of penalty he suffers. The offender is someone who probably does not enjoy enough sanity to control its inclination to unlawful and may or may not be classified as mentally ill. The research covers the incidence and effects of this event on intra-family life. Deals with this issue in order to establish a new legal paradigm in the context of the penalties in the most private sphere of criminal law. The work aims to demonstrate the social relevance of the topic and the need for an effective regulatory sweater for sexual abusers, especially the intra-family and makes a clear proposal for legislative changes with regard to this type of crime, arguing the need to adapt the law the objective reality. It argues that psychoanalytic treatment of offenders as a means of punishment is more important than the simple deprivation of liberty. It argues that the current legislation is incipient and inadequate for such cases and this opinion supported by a significant number of experts. This is not to defend this criminal who practice sexual abuse, but to seek solutions to impunity and respect for the principle of individualization of punishment.

To examine whether change in total sleep time during an integrative, behavioral sleep intervention is associated with aggression. Specifically, we tested whether adolescents who reported experiencing aggressive thoughts or actions after treatment had worse treatment trajectories (e.g., less total sleep time across treatment) than adolescents with no aggressive thoughts or actions after treatment. Nonpharmacologic open trial with 9 weeks of weekly assessment. University of Arizona Sleep Research Laboratory Twenty-three adolescents recently treated for substance abuse in outpatient community centers. Six-week integrative, behavioral sleep intervention. Weekly sleep-summary indexes were calculated from daily sleep diaries and entered as dependent variables in a series of growth-curve analyses. Statistically significant Session x Post-treatment Aggressive Ideation interactions emerged when predicting changes in total sleep time, gamma13 = 9.76 (SE = 4.12), p aggressive ideation and the frequency of substance use, as assessed at baseline. A similar pattern of results was seen for self-reported aggressive actions occurring during conflicts. These pilot data suggest that inadequate sleep in substance-abusing adolescents may contribute to the experiencing of aggressive thoughts and actions. Limitations include a small sample size and a restricted assessment of aggression. Nonetheless, these findings lend preliminary support to the breadth of therapeutic effectiveness of an integrative, behavioral sleep-therapy program for adolescents with a history of substance abuse and related behaviors.

Attenuation of bulk organic matter, nutrients (N and P), and pathogen indicators during soil passage: Effect of temperature and redox conditions in simulated soil aquifer treatment (SAT)

KAUST Repository

Abel, Chol D T

2012-07-22

Soil aquifer treatment (SAT) is a costeffective natural wastewater treatment and reuse technology. It is an environmentally friendly technology that does not require chemical usage and is applicable to both developing and developed countries. However, the presence of organic matter, nutrients, and pathogens poses a major health threat to the population exposed to partially treated wastewater or reclaimed water through SAT. Laboratory-based soil column and batch experiments simulating SAT were conducted to examine the influence of temperature variation and oxidation-reduction (redox) conditions on removal of bulk organic matter, nutrients, and indicator microorganisms using primary effluent. While an average dissolved organic carbon (DOC) removal of 17.7 % was achieved in soil columns at 5 °C, removal at higher temperatures increased by 10 % increments with increase in temperature by 5 °C over the range of 15 to 25 °C. Furthermore, soil column and batch experiments conducted under different redox conditions revealed higher DOC removal in aerobic (oxic) experiments compared to anoxic experiments. Aerobic soil columns exhibited DOC removal 15 % higher than that achieved in the anoxic columns, while aerobic batch showed DOC removal 7.8 % higher than the corresponding anoxic batch experiments. Ammonium-nitrogen removal greater than 99 % was observed at 20 and 25 °C, while 89.7 % was removed at 15 °C, but the removal substantially decreased to 8.8 % at 5 °C. While ammonium-nitrogen was attenuated by 99.9 % in aerobic batch reactors carried out at room temperature, anoxic experiments under similar conditions revealed 12.1 % ammonium-nitrogen reduction, corresponding to increase in nitrate-nitrogen and decrease in sulfate concentration. © Springer Science+Business Media B.V. 2012.

SAT, a flexible and optimized Web application for SSR marker development

Rami Jean-François

2007-11-01

Full Text Available Abstract Background Simple Sequence Repeats (SSRs, or microsatellites, are among the most powerful genetic markers known. A common method for the development of SSR markers is the construction of genomic DNA libraries enriched for SSR sequences, followed by DNA sequencing. However, designing optimal SSR markers from bulk sequence data is a laborious and time-consuming process. Results SAT (SSR Analysis Tool is a user-friendly Web application developed to minimize tedious manual operations and reduce errors. This tool facilitates the integration, analysis and display of sequence data from SSR-enriched libraries. SAT is designed to successively perform base calling and quality evaluation of chromatograms, eliminate cloning vector, adaptors and low quality sequences, detect chimera or partially digested sequences, search for SSR motifs, cluster and assemble the redundant sequences, and design SSR primer pairs. An additional virtual PCR step establishes primer specificity. Users may modify the different parameters of each step of the SAT analysis. Although certain steps are compulsory, such as SSR motifs search and sequence assembly, users do not have to run the entire pipeline, and they can choose selectively which steps to perform. A database allows users to store and query results, and to redo individual steps of the workflow. Conclusion The SAT Web application is available at http://sat.cirad.fr/sat, and a standalone command-line version is also freely downloadable. Users must send an email to the SAT administrator tropgene@cirad.fr to request a login and password.

Two kinds of cloud products obtained from Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO), CloudSat, and Moderate Resolution Imaging Spectroradiometer (MODIS) are compared and analyzed in this study: Clouds and the Earth's Radiant Energy System (CERES)-CALIPSO-CloudSat-MODIS (CCCM) product and CloudSat radar-lidar products such as GEOPROF-LIDAR and FLXHR-LIDAR. Compared to GEOPROF-LIDAR, low-level (40°). The difference occurs when hydrometeors are detected by CALIPSO lidar but are undetected by CloudSat radar. In the comparison of cloud radiative effects (CREs), global mean differences between CCCM and FLXHR-LIDAR are mostly smaller than 5 W m-2, while noticeable regional differences are found. For example, CCCM shortwave (SW) and longwave (LW) CREs are larger than FXLHR-LIDAR along the west coasts of Africa and America because the GEOPROF-LIDAR algorithm misses shallow marine boundary layer clouds. In addition, FLXHR-LIDAR SW CREs are larger than the CCCM counterpart over tropical oceans away from the west coasts of America. Over midlatitude storm-track regions, CCCM SW and LW CREs are larger than the FLXHR-LIDAR counterpart.

In recent years, CubeSats have considerably extended their range of possible applications, from a low cost means to train students and young researchers in space related activities up to possible complementary solutions to larger missions. Increasingly popular, whereas CubeSats are still not a solution for all types of missions, they offer the possibility of performing ambitious scientific experiments. Especially worth considering is the possibility of performing Distributed Space Missions, in which CubeSat systems can be used to increase observation sampling rates and resolutions, as well as to perform tasks that a single satellite is unable to handle. The cost of access to space for traditional Earth Observation (EO) missions is still quite high. Efficient architecture design would allow reducing mission costs by employing CubeSat systems, while maintaining a level of performance that, for some applications, could be close to that provided by larger platforms, and decreasing the time needed to design and deploy a fully functional constellation. For these reasons many countries, including developing nations, agencies and organizations are looking to CubeSat platforms to access space cheaply with, potentially, tens of remote sensing satellites. During disaster management, real-time, fast and continuous information broadcast is a fundamental requirement. In this sense, a constellation of small satellites can considerably decrease the revisit time (defined as the time elapsed between two consecutive observations of the same point on Earth by a satellite) over remote areas, by increasing the number of spacecraft properly distributed in orbit. This allows collecting as much data as possible for the use by Disaster Management Centers. This paper describes the characteristics of a constellation of CubeSats built to enable access over the most remote regions of Brazil, supporting an integrated system for mitigating environmental disasters in an attempt to prevent the

Denial of human rights, gender disparities, and living in a war zone can be associated with severe depression and poor social functioning, especially for female drug abusers. This study of Afghan women in drug abuse treatment (DAT) centers assesses (a) the extent to which these women have experienced human rights violations and mental health problems prior to entering the DAT centers, and (b) whether there are specific risk factors for human rights violations among this population. A total of 176 in-person interviews were conducted with female patients admitted to three drug abuse treatment centers in Afghanistan in 2010. Nearly all women (91%) reported limitations with social functioning. Further, 41% of the women indicated they had suicide ideation and 27% of the women had attempted suicide at least once 30 days prior to entering the DAT centers due to feelings of sadness or hopelessness. Half of the women (50%) experienced at least one human rights violation in the past year prior to entering the DAT centers. Risk factors for human rights violations among this population include marital status, ethnicity, literacy, employment status, entering treatment based on one's own desire, limited social functioning, and suicide attempts. Conclusions stemming from the results are discussed.

Substance Abuse Counselors' Recovery Status and Self-Schemas: Preliminary Implications for Empirically Supported Treatment Implementation.

Science.gov (United States)

Nielson, Elizabeth M

2016-01-01

The purpose of this paper is to better understand the relationship between substance abuse counselors' personal recovery status, self-schemas, and willingness to use empirically supported treatments for substance use disorders. A phenomenological qualitative study enrolled 12 practicing substance abuse counselors. Within this sample, recovering counselors tended to see those who suffer from addiction as qualitatively different from those who do not and hence themselves as similar to their patients, while nonrecovering counselors tended to see patients as experiencing a specific variety of the same basic human struggles everyone experiences, and hence also felt able to relate to their patients' struggles. Since empirically supported treatments may fit more or less neatly within one or the other of these viewpoints, this finding suggests that counselors' recovery status and corresponding self-schemas may be related to counselor willingness to learn and practice specific treatments.

Does comorbid alcohol and substance abuse affect electroconvulsive therapy outcome in the treatment of mood disorders?

Science.gov (United States)

Moss, Lori; Vaidya, Nutan

2014-03-01

Antidepressant medications remain the principal agents used to treat patients with mood disorders, although 30% to 40% of these patients do not improve. One of the factors associated with poor medication response is alcohol and substance abuse. Persons with mood disorders are at the greatest risk for suicide, and alcoholism is a significant additional risk factor. Electroconvulsive therapy (ECT) is shown to be the most effective treatment for major depression especially when associated with psychosis, catatonia, and suicide intent. However, similar to most antidepressant trials, patients with depression and comorbid alcohol and substance abuse are excluded from ECT efficacy studies. Through a retrospective chart review, we compared response to ECT in patients with mood disorder and comorbid alcohol and drug abuse to those with mood disorder only. From 2004 to 2010, 80 patients with mood disorder received ECT. Fifty of these had comorbid alcohol or drug abuse. Using a 10-item psychopathology scale, we compared pre- and post-ECT symptom severity between the 2 groups. Outcome was determined by measuring a decrease in the pre-ECT and post-ECT score using Wilcoxon rank tests, with statistical significance at P = 0.05. There was no difference between the 2 groups in most demographics, ECT medication, or seizure quality. There was no difference in ECT outcome between those with comorbid alcohol abuse and those without based on percent decrease in pre- and post-ECT symptom scores (abuse: mean [SD], 0.89 [0.2] vs nonabuse: mean [SD], 0.93 [0.16]; Wilcoxon, 1332; P = 0.086). When we compared those who met the criteria for alcohol or drug dependence (19 patients) with those with no abuse, there was a trend for the dependence group to not do as well (dependence: mean [SD], 0.83 [0.25] vs nonabuse: mean [SD], 0.93 [0.16]; Wilcoxon, 405; P = 0.053). Those with combined drug and alcohol abuse (18 patients) did have a significantly worse outcome (combined: mean [SD], 0.82 [0

Meijer, Y. J.; Ingmann, P.; Löscher, A.

2012-04-01

The CarbonSat candidate mission is part of ESA's Earth Explorer Programme. In 2010, two candidate opportunity missions had been selected for feasibility and preliminary definition studies. The missions, called FLEX and CarbonSat, are now in competition to become ESA's eighth Earth Explorer, both addressing key climate and environmental change issues. In this presentation we will provide a mission overview of CarbonSat with a focus on science. CarbonSat's primary mission objective is the quantification and monitoring of CO2 and CH4 sources and sinks from the local to the regional scale for i) a better understanding of the processes that control carbon cycle dynamics and ii) an independent estimate of local greenhouse gas emissions (fossil fuel, geological CO2 and CH4, etc.) in the context of international treaties. A second priority objective is the monitoring/derivation of CO2 and CH4 fluxes on regional to global scale. These objectives will be achieved by a unique combination of frequent, high spatial resolution (2 x 2 km2) observations of XCO2 and XCH4 coupled to inverse modelling schemes. The required random error of a single measurement at ground-pixel resolution is of the order of between 1 and 3 ppm for XCO2 and between 9 and 17 ppb for XCH4. High spatial resolution is essential in order to maximize the probability for clear-sky observations and to identify flux hot spots. Ideally, CarbonSat shall have a wide swath allowing a 6-day global repeat cycle. The CarbonSat observations will enable CO2 emissions from coal-fired power plants, localized industrial complexes, cities, and other large emitters to be objectively assessed at a global scale. Similarly, the monitoring of natural gas pipelines and compressor station leakage will become feasible. The detection and quantification of the substantial geological greenhouse gas emission sources such as seeps, volcanoes and mud volcanoes will be achieved for the first time. CarbonSat's Greenhouse Gas instrument will

The Cryogenic On-orbit Liquid Depot-Storage, Acquisition, and Transfer (COLD-SAT) satellite presents some unique safety issues. The feasibility study conducted at NASA-Lewis desired a systems safety program that would be involved from the initial design in order to eliminate and/or control the inherent hazards. Because of this, a hazards analysis method was needed that: (1) identified issues that needed to be addressed for a feasibility assessment; and (2) identified all potential hazards that would need to be controlled and/or eliminated during the detailed design phases. The developed analysis method is presented as well as the results generated for the COLD-SAT system.

Sampling and sensitivity analyses tools (SaSAT for computational modelling

Directory of Open Access Journals (Sweden)

Wilson David P

2008-02-01

Full Text Available Abstract SaSAT (Sampling and Sensitivity Analysis Tools is a user-friendly software package for applying uncertainty and sensitivity analyses to mathematical and computational models of arbitrary complexity and context. The toolbox is built in Matlab®, a numerical mathematical software package, and utilises algorithms contained in the Matlab® Statistics Toolbox. However, Matlab® is not required to use SaSAT as the software package is provided as an executable file with all the necessary supplementary files. The SaSAT package is also designed to work seamlessly with Microsoft Excel but no functionality is forfeited if that software is not available. A comprehensive suite of tools is provided to enable the following tasks to be easily performed: efficient and equitable sampling of parameter space by various methodologies; calculation of correlation coefficients; regression analysis; factor prioritisation; and graphical output of results, including response surfaces, tornado plots, and scatterplots. Use of SaSAT is exemplified by application to a simple epidemic model. To our knowledge, a number of the methods available in SaSAT for performing sensitivity analyses have not previously been used in epidemiological modelling and their usefulness in this context is demonstrated.

Sundström, Mira; Pelander, Anna; Simojoki, Kaarlo; Ojanperä, Ilkka

2016-01-01

The most severe consequences of drug abuse include infectious diseases, overdoses, and drug-related deaths. As the range of toxicologically relevant compounds is continually changing due to the emergence of new psychoactive substances (NPS), laboratories are encountering analytical challenges. Current immunoassays are insufficient for determining the whole range of the drugs abused, and a broad-spectrum screening method is therefore needed. Here, the patterns of drug abuse in two groups of drug users were studied from urine samples using a comprehensive screening method based on high-resolution time-of-flight mass spectrometry. The two groups comprised drug abusers undergoing opioid maintenance treatment (OMT) or drug withdrawal therapy and routinely visiting a rehabilitation clinic, and drug abusers with irregular attendance at a harm reduction unit (HRU) and suspected of potential NPS abuse. Polydrug abuse was observed in both groups, but was more pronounced among the HRU subjects with a mean number of concurrent drugs per sample of 3.9, whereas among the regularly treated subjects the corresponding number was 2.1. NPS and pregabalin were more frequent among HRU subjects, and their abuse was always related to drug co-use. The most common drug combination for an HRU subject included amphetamine, cannabis, buprenorphine, benzodiazepine, and alpha-pyrrolidinovalerophenone. A typical set of drugs for treated subjects was buprenorphine, benzodiazepine, and occasionally amphetamine. Abuse of several concurrent drugs poses a higher risk of drug intoxication and a threat of premature termination of OMT. Since the subjects attending treatment used fewer concurrent drugs, this treatment could be valuable in reducing polydrug abuse. Copyright © 2015 John Wiley & Sons, Ltd.

Mothership - Affordable Exploration of Planetary Bodies through Individual Nano-Sats and Swarms

One concept to enable broad participation in the scientific exploration of small bodies is the Mothership mission architecture which delivers third-party nano-sats, experiments, and sensors to a near Earth asteroid or comet. Deep Space Industries' Mothership service includes delivery of nano-sats, communication to Earth, and visuals of the asteroid surface and surrounding area. It allows researchers to house their instruments in a low-cost nano-sat platform that does not require the high-performance propulsion or deep space communication capabilities that otherwise would be required for a solo asteroid mission. This enables organizations with relatively low operating budgets to closely examine an asteroid with highly specialized sensors of their own choosing, while the nano-sats can be built or commissioned by a variety of smaller institutions, companies, or agencies. In addition, the Mothership and its deployed nano-sats can offer a platform for instruments which need to be distributed over multiple spacecraft. The Mothership is designed to carry 10 to 12 nano-sats, based upon a variation of the Cubesat standard, with some flexibility on the specific geometry. The Deep Space Nano-Sat reference design is a 14.5 cm cube, which accomodates the same volume as a traditional 3U Cubesat. This design was found to be more favorable for deep space due to its thermal characteristics. The CubeSat standard was originally designed with operations in low Earth orbit in mind. By deliberately breaking the standard, Deep Space Nano-Sats offer better performance with less chance of a critical malfunction in the more hostile deep space environment. The first mission can launch as early as Q4 2017, with subsequent, regular launches through the 2020's.

Alcohol abuse and related disorders treatment of alcohol dependence

Full Text Available Alcohol abuse and alcoholism are the leading causes of worse health and increased mortality rates. Excessive alcohol consumption is the third leading cause of the global burden of diseases and a leading factor for lower lifespan and higher mortality. Alcohol abuse decreases working capacity and efficiency and requires the increased cost of the treatment of alcohol-induced disorders, which entails serious economic losses. The unfavorable medical and social consequences of excessive alcohol use determine the importance of effective treatment for alcoholism. The goals of rational pharmacotherapy of alcohol dependence are to enhance GABA neurotransmission, to suppress glutamate neurotransmission, to act on serotonin neurotransmission, to correct water-electrolyte balance, and to compensate for thiamine deficiency. Alcoholism treatment consists of two steps: 1 the prevention and treatment of alcohol withdrawal syndrome and its complications (withdrawal convulsions and delirium alcoholicum; 2 antirecurrent (maintenance therapy. Benzodiazepines are the drugs of choice in alleviating alcohol withdrawal and preventing its convulsive attacks and delirium alcoholicum. Diazepam and chlordiazepoxide are most commonly used for this purpose; the safer drugs oxazepam and lorazepam are given to the elderly and patients with severe liver lesions. Anticonvulsants having normothymic properties, such as carbamazepine, valproic acid, topiramate, and lamotrigine, are a definite alternative to benzodiazepines. The traditional Russian clinical practice (clearance detoxification has not a scientific base or significant impact on alcohol withdrawal-related states in addicts. Relapse prevention and maintenance therapy for alcohol dependence are performed using disulfiram, acamprosate, and naltrexone; since 2013 the European Union member countries have been using, besides these agents, nalmefene that is being registered in Russia.

Care offered in these settings will engage substance-using patients in an integrated and patient-centered environment that addresses physical and mental health comorbidities and follows a chronic care model. This expansion of SUD services presents a great need for evidence-based practices useful in general medical settings, and reveals several research gaps to be addressed. The National Drug Abuse Treatment Clinical Trials Network of the National Institute on Drug Abuse can serve an important role in this endeavor. High-priority research gaps are highlighted in this commentary. A discussion follows on how the National Drug Abuse Treatment Clinical Trials Network can transform to address changing patterns in SUD care to efficiently generate evidence to guide SUD treatment practice within the context of recent US health care legislation.

The objectives of the present study were to estimate the psychiatric comorbidity of Taiwanese heroin users seeking treatment and to identify the gender differences in psychiatric comorbidity and drug use behavior. Subjects were interviewed using a structured questionnaire on drug use behavior and the Mini International Neuropsychiatric Interview for psychiatric disorders. Of the subjects, 58.5% of the male and 62.5% of the female subjects had at least one non-substance-use axis I psychiatric disorder or antisocial personality disorder. Compared to male subjects, female subjects were younger, were less educated, had higher rates of unemployment and had earlier onset of illicit drug use. Female subjects were 11-fold more likely than male subjects to exhibit suicidal behavior. Among heroin abusers in the present study, female subjects were more widely exposed to unfavorable social factors and had substantially higher incidence of suicidal behavior than male subjects. Drug treatment centers should be aware of these gender differences and pay particular attention to comorbid depressive disorders and suicidal behavior of female heroin abusers.

Fennell, D C; Fishel, A H

1998-01-01

To examine the effects of a structured, time-limited parent training group on abusive or potentially abusive parents. A pretest-posttest control group design was used with consenting parents (N = 18) to examine the effects of Systematic Training for Effective Parenting (STEP) on abusive parents' perceptions of their children's behaviors and on the parents' potential to physically abuse. The Adlerian Parental Assessment of Child Behavior Scale and the Child Abuse Potential Inventory were used to measure treatment effects. After participating in STEP, abusive parents had significantly more positive perceptions of their children and were significantly less potentially abusive. Using volunteers, the project cost an average of $100 for each parent. The research lends empirical support to individual psychology and family systems theory. Future research is indicated using larger samples to examine lay vs. professional leadership of the groups, as well as comparisons of different parenting programs with abusive parents.

2016-01-01

For smokers with substance use disorders (SUD), perceived barriers to quitting smoking include concerns unique to effects on sobriety as well as usual concerns. We expanded our Barriers to Quitting Smoking in Substance Abuse Treatment (BQS-SAT) scale, added importance ratings, validated it, and then used the importance scores to predict smoking treatment response in smokers with substance use disorders (SUD) undergoing smoking treatment in residential treatment programs in two studies (n = 184 and 340). Both components (General Barriers, Weight Concerns) were replicated with excellent internal consistency reliability. Construct validity was supported by significant correlations with pretreatment nicotine dependence, smoking variables, smoking self-efficacy, and expected effects of smoking. General Barriers significantly predicted 1-month smoking abstinence, frequency and heaviness, and 3-month smoking frequency; Weight Concerns predicted 1-month smoking frequency. Implications involve addressing barriers with corrective information in smoking treatment for smokers with SUD. PMID:26979552

Nielson, Elizabeth M.

2016-01-01

Purpose The purpose of this paper is to better understand the relationship between substance abuse counselors’ personal recovery status, self-schemas, and willingness to use empirically supported treatments for substance use disorders. Methods A phenomenological qualitative study enrolled 12 practicing substance abuse counselors. Results Within this sample, recovering counselors tended to see those who suffer from addiction as qualitatively different from those who do not and hence themselves as similar to their patients, while nonrecovering counselors tended to see patients as experiencing a specific variety of the same basic human struggles everyone experiences, and hence also felt able to relate to their patients’ struggles. Discussion Since empirically supported treatments may fit more or less neatly within one or the other of these viewpoints, this finding suggests that counselors’ recovery status and corresponding self-schemas may be related to counselor willingness to learn and practice specific treatments.

The treatment outcome of drug-abusing adolescents treated with a 12-Step approach. The study compares drug use outcome data at 6 and 12 months post-treatment among three groups of adolescents: those who completed treatment, those who did not and those on a waiting list. Also, among treatment completers, residential and outpatient samples were compared on outcome. The treatment site is located in the Minneapolis/St Paul area of Minnesota. Two hundred and forty-five drug clinic-referred adolescents (12-18 years old), all of whom met at least one DSM-III-R substance dependence disorder. One hundred and seventy-nine subjects received either complete or incomplete 12-Step, Minnesota Model treatment and 66 were waiting list subjects. In addition to demographics and clinical background variables, measures included treatment involvement, treatment setting and drug use frequency at intake and follow-up. Absolute and relative outcome analyses indicated that completing treatment was associated with far superior outcome compared to those who did not complete treatment or receive any at all. The percentage of treatment completers who reported either abstinence or a minor lapse for the 12 months following treatment was 53%, compared to 15 and 28% for the incompleter and waiting list groups, respectively. Favorable treatment outcome for drug abuse was about two to three times more likely if treatment was completed. Also, there were no outcome differences between residential and outpatient groups. Alcohol was the most common drug used during the follow-up period, despite cannabis being the preferred drug at intake.

Full Text Available Child abuse is a pervasive social and medical problem that remains a major cause of disability and death among children. The annual incidence of abuse is estimated to be 15 to 42 cases per 1,000 children and appears to be increasing. Fractures are the second most common presentation of physical abuse after skin lesions, and approximately one third of abused children will eventually be seen by an orthopedic surgeon. We report a 7-month-old boy who was suspected to be abused. Our diagnosis was based on findings of multiple fractures, delay in seeking medical treatment and discrepancy between the history of illness and the clinical findings. He sustained multiple fractures in variety of healing, namely fractures on left supracondylar humeri, left radius and ulna, right radius and ulna, both femora, right tibia, and left tibia and fibula. Radiological examination was an important modality in revealing the possibility of abuse on this child. He had received medical treatment, protection, consultation team for the parents and an underway police investigation. (Med J Indones 2004; 13: 59-65 Keywords: child, abuse

Full Text Available Background Drug abuse is a major problem in the communities and has many harmful effects on human body. Objectives The current study aimed to compare the efficacy of matrix method on anxiety and attitude of male crack abusers referred to addiction treatment centers in Tonkabon, Iran, in 2014. Patients and Methods The current semi -experimental study included 1,000 males referred to addiction treatment centers in Tonkabon with crack abuse history in 2014. Based on Morgan sample volume formula, 278 males with anxiety and higher attitude to drug abuse were randomly selected from 1,000 males referred to addiction treatment centers in Tonkabon. Then, 30 subjects were reselected out of them and equally assigned into two groups of experimental and control, 15 subjects in each group. The experimental group received 24 sessions of 30 - 60 minutes matrix treatment method in group, but the control group received no training. At the end of training period the post-test was carried out. The research findings confirmed the efficacy of matrix method on anxiety and attitude to crack abuse among those referring to the addition treatment center. Results The single covariance analysis of ANCOVA indicated that the value of Eta about 72% of variance of anxiety variable and about 76% of variance of drug abuse variable are taken in to account for variable of group. The intervention was effective in reducing anxiety and attitude to crack in males. Evaluating the adjusted mean showed the effectiveness of matrix method on anxiety and attitude to crack abuse in males. Conclusions The research result showed that matrix method affected the reduction of methamphetamine and attitude to crack abuse in males referred to the addition treatment center.

This study examined suicide ideation, attempts, and subsequent mental health service among a sample of 948 youth from substance abuse treatment facilities across the United States. Youth were surveyed at intake and every 3 months for a 1-year period. Thirty percent of youth reported ideating in at least one interview, and 12% reported attempting suicide; almost half of all youth reported receiving outpatient mental health treatment at least once, and close to one-third of all youth reported being on prescription drugs for an emotional or behavioral problem. Higher levels of conduct disorder symptoms were associated with both ideation and attempts, while higher levels of depressive symptoms and being female were associated with ideation only. Among all youth, older youth were less likely to receive outpatient and prescription drug treatment, and Black and Hispanic youth were less likely to receive prescription drug treatment than White youth. Among youth who reported ideating, those with conduct disorder were less likely to receive prescription drug treatment 3 months later. These findings emphasize a high prevalence of suicide risk behavior in substance abuse treatment programs and provide insight into the specialized treatment youth in substance abuse treatment at risk for suicide currently receive. 2008 APA, all rights reserved

The majority of U.S. adults with substance abuse or dependence are gainfully employed. However, little is known about outcomes among stably employed people in treatment for substance dependence. Participants (N = 212) entering a residential treatment program completed the Addiction Severity Index (ASI) at intake and 6 and 12 months follow-up. Significant improvements were seen in absenteeism, number of employment problem days, and whether their job was in jeopardy 12 months later. Overall, 65% were retained by their original employer. ASI composite alcohol, drug, legal, family, and psychiatric scores also improved significantly. Continuous abstinence was achieved by 65% and 51% at 6 and 12 months, respectively. Although less likely to be referred to treatment by their employer, women responded to treatment as well as men, reporting similar abstinence rates and overall quality of life during the year following discharge from treatment.

Gregory J. Marchant

2005-01-01

Full Text Available The current study examined the effect of high school graduation exams on states' graduation rates, states' aggregated SAT scores, and individual students' SAT scores. Three data sources were used: One source identified states requiring a standardized test for graduation; the NCES provided state aggregated data on graduation rates for the class of 2002; and the College Board provided its 2001 SAT database for all test-takers. After controlling for students' demographic characteristics (e.g., race, family education and income, GPA and class rank, regression analyses revealed that states requiring graduation exams had lower graduation rates and lower SAT scores. Individually, students from states requiring a graduation exam performed more poorly on the SAT than did students from states not requiring an exam. The impact of high stakes tests' on students' motivation to stay in school and on the teaching of critical thinking skills (tested by the SAT are discussed.

Social exclusion, personal control, self-regulation, and stress among substance abuse treatment clients.

The purpose of this study was to examine the relationship of social exclusion, personal control, and self-regulation to perceived stress among individuals who participated in publicly funded substance abuse treatment. Participants entered treatment between June 2006 and July 2007 and completed a 12-month follow-up survey by telephone (n=787). The results of the OLS regression analysis indicate that individuals with greater social exclusion factors (e.g. greater economic hardship, lower subjective social standing, greater perceived discrimination), lower perceived control of one's life, and lower self-regulation had higher perceived stress. Furthermore, a significant interaction was found suggesting a stress-buffering effect of personal control between subjective social standing and perceived stress. Interestingly, income status was not significantly related to perceived stress, while economic hardship, which assesses participants' inability to meet basic expenses, was significantly associated with perceived stress. Future research should examine how to integrate the AA/NA teaching about powerlessness and its role in recovery with the importance of increased personal control and self-control in decreasing perceived stress. Implications for future research and substance abuse treatment are discussed. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Efficient and Reliable Solar Panels for Small CubeSat Picosatellites

Directory of Open Access Journals (Sweden)

Ivo Vertat

2014-01-01

Full Text Available CubeSat picosatellites have a limited area of walls for solar cells assembling and the available area has to be effectively shared with other parts, such as planar antennas, optical sensors, camera lens, and access port. With standard size of solar cell strings, it is not possible to construct a reliable solar panel for CubeSat with redundant strings interconnection. Typical solar panels for CubeSat consist of two solar cell strings serially wired with no redundancy in case of solar string failure. The loss of electric energy from one solar panel can cause a serious problem for most picosatellites due to minimum margin in the blueprints of the picosatellite subsystem power budget. In this paper, we propose a new architecture of solar panels for PilsenCUBE CubeSat with a high level of redundancy in the case of solar string failure or following switched power regulator failure. Our solar panels use a high efficiency triple junction GaInP2/GaAs/Ge in the form of small triangle strings from the Spectrolab Company. A suitable technology for precise solar cell assembling is also discussed, because CubeSat picosatellites are usually developed by small teams with limited access to high-end facilities.

The SAT process objectives as applied to Spanish NPPs are: Perform JTA for selected job positions at the NPPs; develop the associated training plans; develop training support media; prepare training instructors as teachers and as task analysts; develop a SAT database. A lesson-learned from the task assessments conducted at Spanish NPPs is that the final task list should be obtained with full participation of workers so that they feel the final training plan has been developed taking into account their own opinion and experience. The breakdown of the tasks into its elements and the concordant job performance measure was presented. The process of determining knowledge and skills associated with the task elements and the structure and use of the taxonomy codes (for component, system, and academic skills and knowledge) was shown and explained. Based on the Spanish experience, the average time devoted to analyze a complete task is 5.33 person-hours per task. This data has permitted training and plant management to allocate the NPP human resources to support the analysis phase of SAT (which can be very time-consuming)

Back to Basics: Solving Games with SAT

Directory of Open Access Journals (Sweden)

QUER, S.

2016-08-01

Full Text Available Games became popular, within the formal verification community, after their application to automatic synthesis of circuits from specifications, and they have been receiving more and more attention since then. This paper focuses on coding the "Sokoban" puzzle, i.e., a very complex single-player strategy game. We show how its solution can be encoded and represented as a Bounded Model Checking problem, and then solved with a SAT solver. After that, to cope with very complex instances of the game, we propose two different ad-hoc divide-and-conquer strategies. Those strategies, somehow similar to state-of-the-art abstraction-and-refinement schemes, are able to decompose deep Bounded Model Checking instances into easier subtasks, trading-off between efficiency and completeness. We analyze a vast set of difficult hard-to-solve benchmark games, trying to push forward the applicability of state-of-the-art SAT solvers in the field. Those results show that games may provide one of the next frontier for the SAT community.

Introduction to the overlapped cloud properties derived from polar-orbiting (MODIS) and geostationary (GOES-12, -13, Meteosat-8, -9, etc.) meteorological satellites, which are produced at the NASA Langley Research Center (LaRC) cloud research & development team (NASA lead scientist: Dr. Patrick Minnis). Comparison of the LaRC CERES MODIS Edition-3 overlapped cloud properties to the CALIPSO and the CloudSat active sensing data. High clouds and overlapped clouds occur frequently as deduced by CALIPSO (44 & 25%), CloudSat (25 & 4%), and MODIS (37 & 6%). Large fractions of optically-thin cirrus and overlapped clouds are deduced from CALIPSO, but much smaller fractions are from CloudSat and MODIS. For overlapped clouds, the averaged upper-layer CTHs are about 12.8 (CALIPSO), 10.9 (CloudSat) and 10 km (MODIS), and the averaged lower-layer CTHs are about 3.6 (CALIPSO), 3.2 (CloudSat) and 3.9 km (MODIS). Based on comparisons of upper and lower-layer cloud properties as deduced from the MODIS, CALIPSO and CloudSat data, more enhanced passive satellite methods for retrieving thin cirrus and overlapped cloud properties are needed and are under development.

This paper describes the development of a comprehensive treatment program for combat veterans diagnosed with posttraumatic stress disorder (PTSD) and substance abuse (SA). Outcome data are presented on 46 male patients who completed treatment between 1996 and 1998. The treatment approach, defined by a detailed manual, integrates elements of cognitive-behavioral skills training, constructivist theory approaches, SA relapse prevention strategies, and peer social support into a group-focused program. The Clinician-Administered PTSD Scale (CAPS) and the Addiction Severity Index (ASI) were used to assess treatment effectiveness at discharge and 6- and 12-month follow-up. Significant symptom changes revealed on CAPS and ASI scores at discharge and follow-up are analyzed. Discussion focuses on hypotheses regarding treatment effectiveness, study limitations, and suggestions for further research.

Cheng, Tyrone C; Lo, Celia C

2014-01-01

A study with 591 low-income women examined domestic violence's role in treatment seeking for mental health or substance abuse problems. (The women resided in one of two California counties.) Following Aday's behavioral model of health services utilization, the secondary data analysis considered the women's need, enabling, and predisposing factors. Generalized estimating equations analyzed the women's longitudinal records of treatment seeking. Results showed that those in the sample who were likely to seek treatment had experienced three or more controlling behaviors and only one abusive behavior. Multivariate data analysis showed treatment-seeking women were likely to be white and older; responsible for few dependent children; not graduates of high school; employed; not participating in Medicaid; diagnosed; and perceiving a need for treatment. The implications of these results for services and policies are discussed.

Alexithymia in Egyptian Substance Abusers.

El Rasheed, Amany Haroun

2001-03-01

Alexithymia is thought of as a trait that predisposes to drug abuse. Moreover, it is suggested to be related to type of the substance abused, with the worst-case scenario including a worse prognosis as well as tendency to relapse or even not to seek treatment at all. To address this important subject in Egyptian patients, a sample of 200 Egyptian substance abusers was randomly selected from inpatients in the Institute of Psychiatry, Ain Shams University, Egypt. The study also included 200 group-matched controls. DSM-IV criteria were used for assessment of substance use disorders, and toxicologic urine analysis was used to confirm the substances of abuse. Toronto Alexithymia Scale (TAS)-Arabic version was used for assessment of alexithymia. It was found that alexithymia was significantly more prevalent in the substance use disorders group as compared to healthy controls. It was also found that among the substance use disorders group, alexithymics reported more polysubstance abuse, more opiate use (other than heroin IV), lower numbers of hospitalizations, lower numbers of reported relapses, and a lower tendency to relapse as a result of internal cues compared to patients without alexithymia. Statistically significant associations were also found between alexithymia and more benzodiazepine abuse and nonpersistence in treatment. The results suggest that alexithymia should be targeted in a treatment setting for substance use disorders.

Due to demographic changes there will be a fraction of elderly patients with substance use disorders. However, only a few data have been published about elderly abusers of prescription drugs. Since substance abuse is frequently comorbid with psychiatric disorders, treatment in a psychiatric hospital is often needed. In this explorative study elderly people with prescription drug abuse who required psychiatric inpatient treatment should be characterized. This study was part of the gerontopsychiatry study Berlin (Gepsy-B), an investigation of the data of all older inpatients (≥ 65 years) admitted to a psychiatric hospital within a period of 3 years. Among 1266 documented admissions in 110 cases (8.7 %) (mean age: 75.7 ± 7.1 years) prescription drug abuse, mostly of benzodiazepines was diagnosed. Females showed benzodiazepine abuse more often than males. In only a small proportion of the cases the reason for admission was withdrawal of prescribed drugs. 85.5 % suffered from psychiatric comorbidity, mostly depression. As risk factors for abuse depressive symptoms (OR: 3.32) as well as concurrent nicotine (OR: 2.69) or alcohol abuse (OR: 2.14) were calculated. Psychiatric inpatient treatment was primarily not necessary because of prescription drug abuse but because of other psychopathological symptoms. © Georg Thieme Verlag KG Stuttgart · New York.

The National Institute on Drug Abuse established the National Drug Abuse Treatment Clinical Trials Network (CTN) to conduct trials of promising substance abuse treatment interventions in diverse clinical settings and to disseminate results of these trials. This article focuses on three dimensions of CTN's organizational functioning. First, a longitudinal dataset is used to examine CTN's formation as a network of interorganizational interaction among treatment practitioners and researchers. Data indicate strong relationships of interaction and trust, but a decline in problem-centered interorganizational interaction over time. Second, adoption of buprenorphine and motivational incentives among CTN's affiliated community treatment programs (CTPs) is examined over three waves of data. Although adoption is found to increase with CTPs' CTN participation, there is only modest evidence of widespread penetration and implementation. Third, CTPs' pursuit of the CTN's dissemination goals are examined, indicating that such organizational outreach activities are underway and likely to increase innovation diffusion in the future.

Globally, patterns of the use of psychoactive substances have been changing. To evaluate the trend in two five year periods, 1992 to 1997 versus 2002 to 2007, of alcohol and substance use disorders and associated variables in patients admitted to a drug abuse treatment facility. This was a comparative cross-sectional study involving all patients admitted into Drug Abuse Treatment, Education, and Research (DATER), Unit of the Neuropsychiatric Hospital, Aro, Nigeria within the study period. All subjects had a structured psychiatric interview, a physical examination, laboratory investigations and DATER Questionnaire protocols that elicited socio-demographic, drug and family variables. The patients in 2002 to 2007 versus those of 1992 to 1997 were younger (chi squared 13.29; p,0.01). More last borns were using drugs by 2002 to 2007 (chi squared, 11.37; p,0.01). Cannabis was the most abused drug in 2002 to 2007 (53.5%) as compared to cocaine (44%) in 1992 to 1997 (chi squared 35.5; p,0.001). Polydrug abuse was high in the two periods but significantly the drug combination changed to cannabis in combination with alcohol in 2002 to 2007 as against cocaine in combination with opiates in 1992 to 1997 chi squared 45.3, p 0.001). More patients had co-morbid psychiatric disorders in 2000 to 2007 (67.6% as against 38.5% in 1992 to 1999 chi squared 28.32, p,0.001). In both periods, co-morbidity associated with cannabis use rather than any other drug of abuse as the odds ratio was greater than one. The findings in the trend in the two five year periods underscore the imperatives of continuous evaluation of the drug abuse patient population in treatment which may help drive changes in treatment inputs.

To date, few studies have examined the effect of interagency collaboration on substance abuse assessment ity of Southern California and treatment completion for parents who are involved in child welfare. The purpose of this paper is to: (1) describe a statewide, interagency collaborative program aimed at providing targeted substance abuse assessment and treatment to parents engaged in the child welfare system; (2) document the specialized assessment and treatment outcomes for parents engaged through this collaborative program; and (3) determine factors related to successful treatment completion for parents involved in the child welfare system. This is a retrospective study of an open cohort of 13,829 individuals admitted to the New Jersey Child Protection Substance Abuse Initiative (CPSAI) program from October 1, 2009, through September 30, 2010. Data were drawn from two unique administrative data sources. Multivariate Cox regression models were used to explore factors related to successfil treatment completion for parents involved in the child welfare system. Trend analysis for the total sample in the CPSAI program revealed that, of the 10,909 individuals who received a CPSAI assessment, 59% were referred to treatment. Of those referred to treatment, 40% enrolled in a treatment program. Once enrolled in a treatment program, 55% completed or were in the process of completing substance abuse treatment. These findings suggest that when adequate screening and treatment is available through a streamlined process, many of the ethnic and gender disparities present among other populations of individuals seeking treatment are minimized. Utilizing inherent child welfare case factors appears to be an important motivating element that aids parents during the assessment and treatment process.

1996-01-01

The Nuclear Power Training Center Ltd. (NTC) was established in June 1972 to train PWR plant operators. Operator training was started in Apr. 1974. Presently we have three full-scope, control-room simulators. Recently IAEA recommended that its Systematic Approach to Training (SAT) be used for the training of NPP personnel. We thoroughly examined the SAT-based process and compared it against the NTC training program. As a result, we have recognized that the NTC training program satisfies the SAT-based training process. We now intend to improve the feedback step of the NTC training system. Our efforts continue to produce a relevant program at the forefront of our profession. (author)

Impact of dissociation and interpersonal functioning on inpatient treatment for early sexually abused adults

Directory of Open Access Journals (Sweden)

Ellen K. K. Jepsen

2013-12-01

Full Text Available Background: Little is known about the possible predictors of treatment outcome in early chronically sexually abused adults. The current study aimed to investigate what impact initial levels of dissociation and pre-treatment negative change in interpersonal functioning have on treatment response after 3 months of first-phase trauma inpatient treatment as well as after a period of 1 year the patients returned to their usual lives. Methods: The sample comprised 48 inpatients with childhood sexual abuse histories and mixed trauma-related disorders who were examined at discharge and prospectively followed up for a period of 1 year under naturalistic conditions. Outcome variables were general psychiatric symptoms and interpersonal problems as measured with the Symptom Check List-Revised (SCL-R and the Inventory of Interpersonal Problems (IIP Circumplex. Results: The central findings were that pathological dissociation and deterioration in interpersonal functioning prior to admittance predicted general psychiatric symptom levels and interpersonal problems at the end of treatment and at 1-year follow-up. Pathological dissociation, involving memory and identity problems, alone predicted negative outcome at the end of treatment. The findings at 1-year follow-up indicate that it is not pathological dissociation in isolation that affects outcomes, but rather the interaction between dissociation and change in interpersonal functioning prior to treatment. Conclusion: These findings indicate the need of addressing dissociation and interpersonal problems in treatment planning and favor an integrated treatment approach for complex trauma patients. Future research should investigate whether and how this leads to better outcome, including long-term maintenance of gains after the end of treatment.

This study aimed at identifying the factors that contribute to delaying the access of alcohol abuse patients to specific treatment centres in the Autonomous Region of Valencia (Spain). 563 patients from Addictive Behaviours Units (UCA) and Alcohology Units (UA) were interviewed. A survey was conducted which included items on previous requested treatment in other centres and on barriers of accessibility to treatment in specific ambulatory centres. A descriptive analysis and t-student and ANOVA with Scheffé post-hoc tests were carried out. 59.7% of respondents said they had requested previous treatment in non-specific resources due to physical or psychical trouble that they now relate to their alcohol use although they did not do so at the time, in addition to being motivated by their own alcohol abuse (42.8%). The most attended resources were Primary Care and Specialist Unit Care. Women showed a higher demand for treatment in Mental Health Services (p gender differences in barriers that delay access to treatment do exist. It is necessary to build gender-adapted intervention guidelines to be used in Primary Care and Mental Health services to reduce the accessibility barriers to treatment.

Cudmore, Alan

2015-01-01

Current technology and budget trends indicate a shift in satellite architectures from large, expensive single satellite missions, to small, low cost distributed spacecraft missions. At the center of this shift is the SmallSatCubesat architecture. The primary goal of the Pi-Sat project is to create a low cost, and easy to use Distributed Spacecraft Mission (DSM) test bed to facilitate the research and development of next-generation DSM technologies and concepts. This test bed also serves as a realistic software development platform for Small Satellite and Cubesat architectures. The Pi-Sat is based on the popular $35 Raspberry Pi single board computer featuring a 700Mhz ARM processor, 512MB of RAM, a flash memory card, and a wealth of IO options. The Raspberry Pi runs the Linux operating system and can easily run Code 582s Core Flight System flight software architecture. The low cost and high availability of the Raspberry Pi make it an ideal platform for a Distributed Spacecraft Mission and Cubesat software development. The Pi-Sat models currently include a Pi-Sat 1U Cube, a Pi-Sat Wireless Node, and a Pi-Sat Cubesat processor card.The Pi-Sat project takes advantage of many popular trends in the Maker community including low cost electronics, 3d printing, and rapid prototyping in order to provide a realistic platform for flight software testing, training, and technology development. The Pi-Sat has also provided fantastic hands on training opportunities for NASA summer interns and Pathways students.

Recently KAERI has developed severe accident management guidance to establish Korea standard severe accident management system. On the other hand PC-based severe accident training simulator SATS has been developed, which uses MELCOR computing code as the simulation engine. SATS graphically displays and simulates the severe accident progression with interactive user inputs. The control capability of SATS makes a severe accident training course more interesting and effective. In this paper the development and functions of HyperKAMG module are explained. Furthermore easiness and effectiveness of the HyperKAMG-SATS system in severe accident management are described

Implementing solutions to barriers to on-site HIV testing in substance abuse treatment: a tale of three facilities.

Hood, Kristina B; Robertson, Angela A; Baird-Thomas, Connie

2015-04-01

Due to the scarcity of resources for implementing rapid on-site HIV testing, many substance abuse treatment programs do not offer these services. This study sought to determine whether addressing previously identified implementation barriers to integrating on-site rapid HIV testing into the treatment admissions process would increase offer and acceptance rates. Results indicate that it is feasible to integrate rapid HIV testing into existing treatment programs for substance abusers when resources are provided. Addressing barriers such as providing start-up costs for HIV testing, staff training, addressing staffing needs to reduce competing job responsibilities, and helping treatment staff members overcome their concerns about clients' reactions to positive test results is paramount for the integration and maintenance of such programs.

2014-10-01

Systematically identifying reasons that clients enter substance abuse treatment may allow clinicians to immediately focus on issues of greatest relevance to the individual and enhance treatment engagement. We developed the Survey of Treatment Entry Pressures (STEP) to identify the specific factors that precipitated an individual's treatment entry. The instrument contains 121 items from 6 psychosocial domains (i.e., family, financial, social, medical, psychiatric, legal). The current study examined the STEP's psychometric properties. A total of 761 participants from various treatment settings and modalities completed the STEP prior to treatment admission and 4-7 days later. Analyses were performed to examine the instrument's psychometric properties including item response rates, test-retest reliability, internal consistency, and factor structure. The items displayed adequate test-retest reliability and internal consistency within each psychosocial domain. Generally, results from exploratory and confirmatory factor analyses support a 2-factor structure reflecting type of reinforcement schedule. The study provides preliminary support for the psychometric properties of the STEP. The STEP may provide a reliable way for clinicians to characterize and capitalize on a client's treatment motivation early on which may serve to improve treatment retention and therapeutic outcomes. © 2014 Wiley Periodicals, Inc.

Changes in the sexual self-schema of women with a history of childhood sexual abuse following expressive writing treatment.

2017-03-01

Sexual self-schemas are cognitive generalizations about the sexual self that influence the processing of sexually pertinent information and guide sexual behavior. Until recently sexual self-schemas were exclusively assessed with self-report instruments. Recent research using the meaning extraction method, an inductive method of topic modeling, identified 7 unique themes of sexual self-schemas: family and development, virginity, abuse, relationship, sexual activity, attraction, and existentialism from essays of 239 women (Stanton, Boyd, Pulverman, & Meston, 2015). In the current study, these themes were used to examine changes in theme prominence after an expressive writing treatment. Women (n = 138) with a history of childhood sexual abuse completed a 5-session expressive writing treatment, and essays on sexual self-schemas written at pretreatment and posttreatment were examined for changes in themes. Women showed a reduction in the prominence of the abuse, family and development, virginity, and attraction themes, and an increase in the existentialism theme. This study supports the validity of the 7 themes identified by Stanton and colleagues (2015) and suggests that expressive writing may aid women with a history of sexual abuse to process their abuse history such that it becomes a less salient aspect of their sexual self-schemas.

Although p53-mediated cell-cycle arrest, senescence, and apoptosis remain critical barriers to cancer development, the emerging role of p53 in cell metabolism, oxidative responses, and ferroptotic cell death has been a topic of great interest. Nevertheless, it is unclear how p53 orchestrates its activities in multiple metabolic pathways into tumor suppressive effects. Here, we identified the SAT1 (spermidine/spermine N 1 -acetyltransferase 1) gene as a transcription target of p53. SAT1 is a rate-limiting enzyme in polyamine catabolism critically involved in the conversion of spermidine and spermine back to putrescine. Surprisingly, we found that activation of SAT1 expression induces lipid peroxidation and sensitizes cells to undergo ferroptosis upon reactive oxygen species (ROS)-induced stress, which also leads to suppression of tumor growth in xenograft tumor models. Notably, SAT1 expression is down-regulated in human tumors, and CRISPR-cas9-mediated knockout of SAT1 expression partially abrogates p53-mediated ferroptosis. Moreover, SAT1 induction is correlated with the expression levels of arachidonate 15-lipoxygenase (ALOX15), and SAT1-induced ferroptosis is significantly abrogated in the presence of PD146176, a specific inhibitor of ALOX15. Thus, our findings uncover a metabolic target of p53 involved in ferroptotic cell death and provide insight into the regulation of polyamine metabolism and ferroptosis-mediated tumor suppression.

behavioral and psychological results by itself, early trauma may also lead to biological effects. Especially traumas during neuron plasticity phase may lead hypersensitivity of neuroendocrine stress response. Early life stresses are shown to lead changes in corticotrophin releasing factor system in preclinical and clinical phase studies. In the treatment of sexual abuse, emotional process related with trauma should be focused on. This process may be conducted with play therapy. Development of higher level defense mechanism, increasing ego capacity, orientation to social activity and personal activity according to skills is aimed. For the elimination of guiltiness related with stigmatization, the child should be told that it is not herhis fault to incorporate into sexual interaction and the culprit is abuser. It is fairly important for medical staff, school and family to have sufficient information about sexual abuse for prevention and early recognition.

Barriers to Quitting Smoking Among Substance Dependent Patients Predict Smoking Cessation Treatment Outcome.

2016-05-01

For smokers with substance use disorders (SUD), perceived barriers to quitting smoking include concerns unique to effects on sobriety as well as usual concerns. We expanded our Barriers to Quitting Smoking in Substance Abuse Treatment (BQS-SAT) scale, added importance ratings, validated it, and then used the importance scores to predict smoking treatment response in smokers with substance use disorders (SUD) undergoing smoking treatment in residential treatment programs in two studies (n=184 and 340). Both components (general barriers, weight concerns) were replicated with excellent internal consistency reliability. Construct validity was supported by significant correlations with pretreatment nicotine dependence, smoking variables, smoking self-efficacy, and expected effects of smoking. General barriers significantly predicted 1-month smoking abstinence, frequency and heaviness, and 3-month smoking frequency; weight concerns predicted 1-month smoking frequency. Implications involve addressing barriers with corrective information in smoking treatment for smokers with SUD. Copyright © 2016 Elsevier Inc. All rights reserved.

Integration of CubeSat Systems with Europa Surface Exploration Missions

Erdoǧan, Enes; Inalhan, Gokhan; Kemal Üre, Nazım

2016-07-01

Recent studies show that there is a high probability that a liquid ocean exists under thick icy surface of Jupiter's Moon Europa. The findings also show that Europa has features that are similar to Earth, such as geological activities. As a result of these studies, Europa has promising environment of being habitable and currently there are many missions in both planning and execution level that target Europa. However, these missions usually involve extremely high budgets over extended periods of time. The objective of this talk is to argue that the mission costs can be reduced significantly by integrating CubeSat systems within Europa exploration missions. In particular, we introduce an integrated CubeSat-micro probe system, which can be used for measuring the size and depth of the hypothetical liquid ocean under the icy surface of Europa. The systems consist of an entry module that houses a CubeSat combined with driller measurement probes. Driller measurement probes deploy before the system hits the surface and penetrate the surface layers of Europa. Moreover, a micro laser probe could be used to examine the layers. This process enables investigation of the properties of the icy layer and the environment beneath the surface. Through examination of different scenarios and cost analysis of the components, we show that the proposed CubeSat systems has a significant potential to reduce the cost of the overall mission. Both subsystem requirements and launch prices of CubeSats are dramatically cheaper than currently used satellites. In addition, multiple CubeSats may be used to dominate wider area in space and they are expandable in face of potential failures. In this talk we discuss both the mission design and cost reduction aspects.

In the field of mobile satellite communications, a system based on low-earth-orbit satellites (LEO-SAT's) such as the Iridium system has been proposed. The LEO-SAT system is able to offer mobile telecommunication services in high-latitude areas. Rain degradation, fading and shadowing are also expected to be decreased when the system is operated at a high elevation angle. Furthermore, the propagation delay generated in the LEO-SAT system is less pronounced than that in the geostationary orbit satellite (GEO-SAT) system and, in voice services, the effect of the delay is almost negligible. We proposed a concept of a broad-band mobile satellite communication system with LEO-SAT's and Optical ISL. In that system, a fixed L-band (1.6/1.5 GHz) multibeam is used to offer narrow band service to the mobile terminals in the entire area covered by a LEO-SAT and steerable Ka-band (30/20 GHz) spot beams are used for the wide band service. In this paper, we present results of a study of LEO-SAT microwave link between a satellite and a mobile terminal for a broad-band mobile satellite communication system. First, the results of link budget calculations are presented and the antennas mounted on satellites are shown. For a future mobile antenna technology, we also show digital beamforming (DBF) techniques. DBF, together with modulation and/or demodulation, is becoming a key technique for mobile antennas with advanced functions such as antenna pattern calibration, correction, and radio interference suppression. In this paper, efficient DBF techniques for transmitting and receiving are presented. Furthermore, an adaptive array antenna system suitable for this LEO-SAT is presented.

Johannesen, Jason K; Lurie, Jessica B; Fiszdon, Joanna M; Bell, Morris D

2013-01-01

The Social Attribution Task-Multiple Choice (SAT-MC) uses a 64-second video of geometric shapes set in motion to portray themes of social relatedness and intentions. Considered a test of "Theory of Mind," the SAT-MC assesses implicit social attribution formation while reducing verbal and basic cognitive demands required of other common measures. We present a comparability analysis of the SAT-MC and the new SAT-MC-II, an alternate form created for repeat testing, in a university sample (n = 92). Score distributions and patterns of association with external validation measures were nearly identical between the two forms, with convergent and discriminant validity supported by association with affect recognition ability and lack of association with basic visual reasoning. Internal consistency of the SAT-MC-II was superior (alpha = .81) to the SAT-MC (alpha = .56). Results support the use of SAT-MC and new SAT-MC-II as equivalent test forms. Demonstrating relatively higher association to social cognitive than basic cognitive abilities, the SAT-MC may provide enhanced sensitivity as an outcome measure of social cognitive intervention trials.

Conventional (pulse-limited) altimeters determine the sea surface height with an accuracy of a few centimeters over the open ocean. Sea surface heights and tide-gauge sea level serve as each other’s buddy check. However, in coastal areas, altimetry suffers from numerous effects, which degrade its...... conventional altimeters. In this study, we explore the potential of CryoSat-2 to provide valid observations in the Norwegian coastal zone. We do this by comparing time series of CryoSat-2 sea level anomalies with time series of in situ sea level at 22 tide gauges, where the CryoSat-2 sea level anomalies...... are averaged in a 45-km area around each tide gauge. For all tide gauges, CryoSat-2 shows standard deviations of differences and correlations of 16 cm and 61%, respectively. We further identify the ocean tide and inverted barometer geophysical corrections as the most crucial, and note that a large amount...

The behavior along the potabilization process of 29 pharmaceuticals and 12 drugs of abuse identified from a total of 81 compounds at the intake of a drinking water treatment plant (DWTP) has been studied. The DWTP has a common treatment consisting of dioxychlorination, coagulation/flocculation and sand filtration and then water is splitted in two parallel treatment lines: conventional (ozonation and carbon filtration) and advanced (ultrafiltration and reverse osmosis) to be further blended, chlorinated and distributed. Full removals were reached for most of the compounds. Iopromide (up to 17.2 ng/L), nicotine (13.7 ng/L), benzoylecgonine (1.9 ng/L), cotinine (3.6 ng/L), acetaminophen (15.6 ng/L), erythromycin (2.0 ng/L) and caffeine (6.0 ng/L) with elimination efficiencies ≥ 94%, were the sole compounds found in the treated water. The advanced treatment process showed a slightly better efficiency than the conventional treatment to eliminate pharmaceuticals and drugs of abuse. Copyright © 2011 Elsevier Ltd.

Abuse of prescription drugs.

Science.gov (United States)

Wilford, B B

1990-01-01

An estimated 3% of the United States population deliberately misuse or abuse psychoactive medications, with severe consequences. According to the National Institute on Drug Abuse, more than half of patients who sought treatment or died of drug-related medical problems in 1989 were abusing prescription drugs. Physicians who contribute to this problem have been described by the American Medical Association as dishonest--willfully misprescribing for purposes of abuse, usually for profit; disabled by personal problems with drugs or alcohol; dated in their knowledge of current pharmacology or therapeutics; or deceived by various patient-initiated fraudulent approaches. Even physicians who do not meet any of these descriptions must guard against contributing to prescription drug abuse through injudicious prescribing, inadequate safeguarding of prescription forms or drug supplies, or acquiescing to the demands or ruses used to obtain drugs for other than medical purposes.

We present two cases of infants who died under suspicious circumstances. After clinical and legal investigations, non-accidental constrictive asphyxia inflicted by one of the parents was established. The first case presents a to date not yet reported, unique mechanism of trauma. In order to stop his daughter from crying, the father admitted that he sometimes sat on his baby while she was lying on the bed. Occasionally increasing his force by pulling with his hands on the bottom of the bed. In the second case tight swaddling and encircling chest compression was the causative mechanism. In both cases the father was sentenced to imprisonment with mandate psychiatric care. Only two previous reports of this uncommon and relatively unknown cause of child abuse, called constrictive asphyxia, are known. In all reported cases static loading of the chest resulted in rib fractures and demise of the child. This rare abusive mechanism should be known to pediatric radiologists and pathologists.

Burckhardt, Rachel M; Escalante-Semerena, Jorge C

2017-11-01

Soil is a complex niche, where survival of microorganisms is at risk due to the presence of antimicrobial agents. Many microbes chemically modify cytotoxic compounds to block their deleterious effects. Streptothricin is a broad-spectrum antibiotic produced by streptomycetes that affects Gram-positive and Gram-negative bacteria alike. Here we identify the SatA (for s treptothricin a ce t yltransferase A , formerly YyaR) enzyme of Bacillus subtilis as the mechanism used by this soil bacterium to detoxify streptothricin. B. subtilis strains lacking satA were susceptible to streptothricin. Ectopic expression of satA + restored streptothricin resistance to B. subtilis satA ( Bs SatA) strains. Purified Bs SatA acetylated streptothricin in vitro at the expense of acetyl-coenzyme A (acetyl-CoA). A single acetyl moiety transferred onto streptothricin by SatA blocked the toxic effects of the antibiotic. SatA bound streptothricin with high affinity ( K d [dissociation constant] = 1 μM), and did not bind acetyl-CoA in the absence of streptothricin. Expression of B. subtilis satA + in Salmonella enterica conferred streptothricin resistance, indicating that SatA was necessary and sufficient to detoxify streptothricin. Using this heterologous system, we showed that the SatA homologue from Bacillus anthracis also had streptothricin acetyltransferase activity. Our data highlight the physiological relevance of lysine acetylation for the survival of B. subtilis in the soil. IMPORTANCE Experimental support is provided for the functional assignment of gene products of the soil-dwelling bacilli Bacillus subtilis and Bacillus anthracis This study focuses on one enzyme that is necessary and sufficient to block the cytotoxic effects of a common soil antibiotic. The enzyme alluded to is a member of a family of proteins that are broadly distributed in all domains of life but poorly studied in B. subtilis and B. anthracis The initial characterization of the enzyme provides insights into its

Development of a Solar Array Drive Assembly for CubeSat

Science.gov (United States)

Passaretti, Mike; Hayes, Ron

2010-01-01

Small satellites and in particular CubeSats, have increasingly become more viable as platforms for payloads typically requiring much larger bus structures. As advances in technology make payloads and instruments for space missions smaller, lighter and more power efficient, a niche market is emerging from the university community to perform rapidly developed, low-cost missions on very small spacecraft - micro, nano, and picosatellites. In just the last few years, imaging, biological and new technology demonstration missions have been either proposed or have flown using variations of the CubeSat structure as a basis. As these missions have become more complex, and the CubeSat standard has increased in both size (number of cubes) and mass, available power has become an issue. Body-mounted solar cells provide a minimal amount of power; deployable arrays improve on that baseline but are still limited. To truly achieve maximum power, deployed tracked arrays are necessary. To this end, Honeybee Robotics Spacecraft Mechanisms Corporation, along with MMA of Nederland Colorado, has developed a solar array drive assembly (SADA) and deployable solar arrays specifically for CubeSat missions. In this paper, we discuss the development of the SADA.

Interpreting force concept inventory scores: Normalized gain and SAT scores

Directory of Open Access Journals (Sweden)

Jeffrey J. Steinert

2007-05-01

Full Text Available Preinstruction SAT scores and normalized gains (G on the force concept inventory (FCI were examined for individual students in interactive engagement (IE courses in introductory mechanics at one high school (N=335 and one university (N=292 , and strong, positive correlations were found for both populations ( r=0.57 and r=0.46 , respectively. These correlations are likely due to the importance of cognitive skills and abstract reasoning in learning physics. The larger correlation coefficient for the high school population may be a result of the much shorter time interval between taking the SAT and studying mechanics, because the SAT may provide a more current measure of abilities when high school students begin the study of mechanics than it does for college students, who begin mechanics years after the test is taken. In prior research a strong correlation between FCI G and scores on Lawson’s Classroom Test of Scientific Reasoning for students from the same two schools was observed. Our results suggest that, when interpreting class average normalized FCI gains and comparing different classes, it is important to take into account the variation of students’ cognitive skills, as measured either by the SAT or by Lawson’s test. While Lawson’s test is not commonly given to students in most introductory mechanics courses, SAT scores provide a readily available alternative means of taking account of students’ reasoning abilities. Knowing the students’ cognitive level before instruction also allows one to alter instruction or to use an intervention designed to improve students’ cognitive level.

Baktur, Reyhan

2016-01-01

The goal of the Integrated Solar-Panel Antenna Array for CubeSats (ISAAC) project is to design and demonstrate an effective and efficien toptically transparent, high-gain, lightweight, conformal X-band antenna array that is integrated with the solar panels of a CubeSat. The targeted demonstration is for a Near Earth Network (NEN)radio at X-band, but the design can be easilyscaled to other network radios for higher frequencies. ISAAC is a less expensive and more flexible design for communication systemscompared to a deployed dish antenna or the existing integrated solar panel antenna design.

Hospitalization of adolescents for psychiatric and substance abuse treatment. Legal and ethical issues.

Science.gov (United States)

Schwartz, I M

1989-11-01

It has been estimated that as many as 12%-15% of the nations 63 million children are in need of mental health treatment. We have a responsibility to do everything we can to see to it that these children receive the services they need. Unfortunately, there is mounting evidence that a significant proportion of our health care resources are being misspent on the unnecessary and inappropriate hospitalization of children and youths in psychiatric and substance abuse treatment programs. More alarming is the evidence of poor quality programs, abusive practices, and greed. The intense competition to capture a "share of the market" and turn a profit or keep a nonprofit hospital from closing its doors is contributing to unprofessional and unethical advertising and public relations practices. In the end these practices will reflect poorly on the broader mental health and health care community. Hopefully, the stakeholders in the system will recognize these problems and assume a leadership role in turning the situation around. If not, we can expect intervention from forces outside the system (e.g., courts, elected public officials, public interest groups, the business community, and child advocates).

Continuous quality improvement in substance abuse treatment facilities: How much does it cost?

Hunt, Priscillia; Hunter, Sarah B; Levan, Deborah

2017-06-01

Continuous quality improvement (CQI) has grown in the U.S. since the 1970s, yet little is known about the costs to implement CQI in substance abuse treatment facilities. This paper is part of a larger group randomized control trial in a large urban county evaluating the impact of Plan-Study-Do-Act (PDSA)-CQI designed for community service organizations (Hunter, Ober, Paddock, Hunt, & Levan, 2014). Operated by one umbrella organization, each of the eight facilities of the study, four residential and four outpatient substance abuse treatment facilities, selected their own CQI Actions, including administrative- and clinical care-related Actions. Using an activity-based costing approach, we collected labor and supplies and equipment costs directly attributable to CQI Actions over a 12-month trial period. Our study finds implementation of CQI and meeting costs of this trial per facility were approximately $2000 to $10,500 per year ($4500 on average), or $10 to $60 per admitted client. We provide a description of the sources of variation in these costs, including differing intensity of the CQI Actions selected, which should help decision makers plan use of PDSA-CQI.

Behavioral Couples Treatment for Substance Use Disorder: Secondary Effects on the Reduction of Risk for Child Abuse.

Science.gov (United States)

Kelley, Michelle L; Bravo, Adrian J; Braitman, Abby L; Lawless, Adrienne K; Lawrence, Hannah R

2016-03-01

Risk for child abuse was examined prior to and after behavioral couples treatment (BCT) among 61 couples in which one or both parents were diagnosed with substance use disorder (SUD). All couples were residing with one or more school-age children. Mothers and fathers completed pretreatment, post-intervention, and 6-month post-intervention follow-up assessments. Results of piecewise latent growth models tested whether the number of BCT sessions attended and number of days abstinent from drugs and alcohol influenced relationship satisfaction and its growth over time, and in turn if relationship satisfaction and change in relationship satisfaction influenced risk for child abuse. For both mothers and fathers, attending more BCT sessions lead to a direct increase in relationship satisfaction, which in turn led to stronger reductions in risk for child abuse. This effect was maintained from the post-intervention through the 6-month post-intervention follow-up. For fathers, number of days abstinent significantly influenced reduction in child abuse potential at post-intervention via relationship satisfaction. This indirect effect was not present for mothers. The overall benefits of BCT on mothers' and fathers' risk for child abuse suggest that BCT may have promise in reducing risk for child abuse among couples in which one or both parents have SUD.

Identifying the substance abuse treatment needs of caregivers involved with child welfare.

Science.gov (United States)

Chuang, Emmeline; Wells, Rebecca; Bellettiere, John; Cross, Theodore P

2013-07-01

Parental substance use significantly increases risk of child maltreatment, but is often under-identified by child protective services. This study examined how agency use of standardized substance use assessments and child welfare investigative caseworker education, experience, and caseload affected caseworkers' identification of parental substance abuse treatment needs. Data are from a national probability sample of permanent, primary caregivers involved with child protective services whose children initially remained at home and whose confidential responses on two validated instruments indicated harmful substance use or dependence. Investigative caseworkers reported use of a formal assessment in over two thirds of cases in which substance use was accurately identified. However, weighted logistic regression indicated that agency provision of standardized assessment instruments was not associated with caseworker identification of caregiver needs. Caseworkers were also less likely to identify substance abuse when their caseloads were high and when caregivers were fathers. Implications for agency practice are discussed.

After the successful launch of CryoSat-2 in April 2010, the first direct validation campaign of the satellite is planned for spring 2011. DTU Space has been involved in ESA’s CryoSat Validation Experiment (CryoVEx) with airborne activities since 2003. To validate the prelaunch performance...... of the CryoSat radar altimeter (SIRAL), an airborne version of the SIRAL altimeter (ASIRAS) has been flown together with a laser scanner in 2006 and 2008. Of particular interest is to study the penetration depth of the radar altimeter over both land- and sea ice. This can be done by comparing the radar...... and laser measurements with in situ observations. Here, an overview of the prelaunch airborne campaigns is given, together with results of the ASIRAS performance over land- and sea ice. The observations, used in this study, are obtained from the Greenland ice sheet and from both multiyear and first year sea...

SAT2 Foot-and-Mouth Disease Virus Structurally Modified for Increased Thermostability.

Foot-and-mouth disease virus (FMDV), particularly strains of the O and SAT serotypes, is notoriously unstable. Consequently, vaccines derived from heat-labile SAT viruses have been linked to the induction of immunity with a poor duration and hence require more frequent vaccinations to ensure protection. In silico calculations predicted residue substitutions that would increase interactions at the interpentamer interface, supporting increased stability. We assessed the stability of the 18 recombinant mutant viruses in regard to their growth kinetics, antigenicity, plaque morphology, genetic stability, and temperature, ionic, and pH stability by using Thermofluor and inactivation assays in order to evaluate potential SAT2 vaccine candidates with improved stability. The most stable mutant for temperature and pH stability was the S2093Y single mutant, while other promising mutants were the E3198A, L2094V, and S2093H single mutants and the F2062Y-H2087M-H3143V triple mutant. Although the S2093Y mutant had the greatest stability, it exhibited smaller plaques, a reduced growth rate, a change in monoclonal antibody footprint, and poor genetic stability properties compared to those of the wild-type virus. However, these factors affecting production can be overcome. The addition of 1 M NaCl was found to further increase the stability of the SAT2 panel of viruses. The S2093Y and S2093H mutants were selected for future use in stabilizing SAT2 vaccines. IMPORTANCE Foot-and-mouth disease virus (FMDV) causes a highly contagious acute vesicular disease in cloven-hoofed livestock and wildlife. The control of the disease by vaccination is essential, especially at livestock-wildlife interfaces. The instability of some serotypes, such as SAT2, affects the quality of vaccines and therefore the duration of immunity. We have shown that we can improve the stability of SAT2 viruses by mutating residues at the capsid interface through predictive modeling. This is an important finding for

SAT for NPP personnel training in USA

International Nuclear Information System (INIS)

Spinney, R.

1995-01-01

This discussion addressed the experience with the application of SAT at USA NPPs. In particular, the transition of NPP training processes, staff composition, and reporting structure from the TMI accident to present. As well, oversight and guidance activities of the INPO and more intensive inspection by the NRC began during this period. The average NPP training staff grew to 30-40 per unit, along with a change in reporting line from plant to corporate management. With the reduction of resources occurring in the late 1980s, overall training staff size decreased, the composition changed, and reporting line reverted to plant management. The overall lessons-learned for application of the SAT consisted of the need for simplification, management involvement, and exploitation of the technology

2014-03-01

In February 2012, a massive new foot-and-mouth disease (FMD) outbreak struck Egypt. In this work, one-step RT-PCR assays were used for in-house detection and differentiation of foot-and-mouth disease virus (FMDV) in Egypt in this year using pan-serotypic and serotype-targeting sequence primers. FMDV SAT2 was the dominant virus in the examined isolates from the epidemic. The complete VP1 coding regions of two isolates were sequenced. The two isolates had 99.2 % sequence identity to most contemporary Egyptian SAT2 reference viruses, whereas they had 89.7-90.1 % identity to the SAT2/EGY/2/2012 isolate, which was collected from Alexandria, Egypt, and previously sequenced by WRLFMD. Phylogenetic analysis showed that Egypt had one topotype and two lineage of FMDV SAT2 in 2012. The Egyptian and the Palestinian 2012 strains were associated mainly with topotype VII, lineage SAT2/VII/Ghb-12, while the virus isolated from Alexandria Governorate belonged to the SAT2/VII/Alx-12 lineage. Topotype VII also comprised lineages that included strains isolated from Libya in 2012 and 2003. Furthermore, within the same topotype, the Egyptian SAT2/2012 isolates were related to strains from Saudi Arabia, Sudan, Eritrea, Cameroon and Nigeria. Nevertheless, more epidemiological work with neighboring countries is needed to prevent cross-border spread of disease and to reach a precise conclusion about the origin of the 2012 FMDV SAT2 emergency in the Middle East.

SAT Encoding of Unification in EL

Science.gov (United States)

Baader, Franz; Morawska, Barbara

Unification in Description Logics has been proposed as a novel inference service that can, for example, be used to detect redundancies in ontologies. In a recent paper, we have shown that unification in EL is NP-complete, and thus of a complexity that is considerably lower than in other Description Logics of comparably restricted expressive power. In this paper, we introduce a new NP-algorithm for solving unification problems in EL, which is based on a reduction to satisfiability in propositional logic (SAT). The advantage of this new algorithm is, on the one hand, that it allows us to employ highly optimized state-of-the-art SAT solvers when implementing an EL-unification algorithm. On the other hand, this reduction provides us with a proof of the fact that EL-unification is in NP that is much simpler than the one given in our previous paper on EL-unification.

Full Text Available Background: Childhood sexual abuse (CSA is a common occurrence and a robust, yet non-specific, predictor of adult psychopathology. While many demographic and abuse factors have been shown to impact this relationship, their common and specific effects remain poorly understood. Objective: This study sought to assess the prevalence of Axis I disorders in a large sample of help-seeking victims of sexual trauma, and to examine the common and specific effects of demographic and abuse characteristics across these different diagnoses. Method: The participants were attendees at four treatment centres in Denmark that provide psychological therapy for victims of CSA (N=434. Axis I disorders were assessed using the Millon Clinical Multiaxial Inventory-III (MCMI-III. Multivariate logistic regression analysis was used to examine the associations between CSA characteristics (age of onset, duration, number of abusers, number of abusive acts and 10 adult clinical syndromes. Results: There was significant variation in the prevalence of disorders and the abuse characteristics were differentially associated with the outcome variables. Having experienced sexual abuse from more than one perpetrator was the strongest predictor of psychopathology. Conclusions: The relationship between CSA and adult psychopathology is complex. Abuse characteristics have both unique and shared effects across different diagnoses.

Substance abuse: medical and slang terminology.

Science.gov (United States)

Hamid, Humera; El-Mallakh, Rif S; Vandeveir, Keith

2005-03-01

Substance abuse is among one of the major problems plaguing our society. It has come to the attention of several healthcare professionals that a communication gap exists between themselves and substance abusers. Most of the time the substance abusers are only familiar with the slang terms of abused substances, a terminology that medical professionals are usually unaware of. This paper is an attempt to close that communication gap, allowing health care professionals to understand the slang terminology that their patients use, thus enabling them to make appropriate treatment decisions. In addition, the article presents some key features (including active ingredient, pharmacological classification, medical use, abuse form, usage method, combinations used, effects sought, long-term possible effects, and detectability in urine) of the most commonly abused substances.

Pseudo LRM waveforms from CryoSat SARin acquisition

Scagliola, Michele; Fornari, Marco; Bouffard, Jerome; Parrinello, Tommaso; Féménias, Pierre

2016-04-01

CryoSat was launched on the 8th April 2010 and is the first European ice mission dedicated to the monitoring of precise changes in the thickness of polar ice sheets and floating sea ice. The main payload of CryoSat is a Ku-band pulsewidth limited radar altimeter, called SIRAL (Synthetic interferometric radar altimeter). When commanded in SARIn (synthetic aperture radar interferometry) mode, through coherent along-track processing of the returns received from two antennas, the interferometric phase related to the first arrival of the echo is used to retrieve the angle of arrival of the scattering in the across-track direction. When SIRAL operates in SAR or SARin mode, the obtained waveforms have an along-track resolution and a speckle reduction which is increased with respect to the pulse-limited waveforms. Anyway, in order to analyze the continuity of the geophysical retrieved parameters among different acquisition modes, techniques to transform SARin mode data to pseudo-LRM mode data are welcome. The transformation process is known as SAR reduction and it is worth recalling here that only approximate pseudo-LRM waveforms can be obtained in case of closed burst acquisitions, as SIRAL operates. A SAR reduction processing scheme has been developed to obtain pseudo-LRM waveforms from CryoSat SARin acquisition. As a trade-off between the along-track length on Earth surface contributing to one SARin pseudo-LRM waveform and the noisiness of the waveform itself, it has been chosen a SAR reduction approach based on the averaging of all the SARin echoes received each 20Hz, resulting in one pseudo-LRM waveform for each SARin burst given the SARin burst repetition period. SARin pseudo-LRM waveforms have been produced for CryoSat acquisition both on ice and sea surfaces, aiming at verifying the continuity of the retracked surface height over the ellipsoid between genuine LRM products and pseudo-LRM products. Moreover, the retracked height from the SARin pseudo-LRM has been

DebriSat - A Planned Laboratory-Based Satellite Impact Experiment for Breakup Fragment Characterization

Liou, J.-C.; Fitz-Coy, N.; Werremeyer, M.; Huynh, T.; Voelker, M.; Opiela, J.

2012-01-01

DebriSat is a planned laboratory ]based satellite hypervelocity impact experiment. The goal of the project is to characterize the orbital debris that would be generated by a hypervelocity collision involving a modern satellite in low Earth orbit (LEO). The DebriSat project will update and expand upon the information obtained in the 1992 Satellite Orbital Debris Characterization Impact Test (SOCIT), which characterized the breakup of a 1960 's US Navy Transit satellite. There are three phases to this project: the design and fabrication of an engineering model representing a modern, 50-cm/50-kg class LEO satellite known as DebriSat; conduction of a laboratory-based hypervelocity impact to catastrophically break up the satellite; and characterization of the properties of breakup fragments down to 2 mm in size. The data obtained, including fragment size, area ]to ]mass ratio, density, shape, material composition, optical properties, and radar cross ]section distributions, will be used to supplement the DoD fs and NASA fs satellite breakup models to better describe the breakup outcome of a modern satellite. Updated breakup models will improve mission planning, environmental models, and event response.

Low- and middle-income countries (LMIC) lack the research infrastructure and capacity to conduct rigorous substance abuse and mental health effectiveness clinical trials to guide clinical practice. A partnership between the Florida Node Alliance of the United States National Drug Abuse Treatment Clinical Trials Network and the National Institute of Psychiatry in Mexico was established in 2011 to improve substance abuse practice in Mexico. The purpose of this partnership was to develop a Mexican national clinical trials network of substance abuse researchers and providers capable of implementing effectiveness randomized clinical trials in community-based settings. A technology transfer model was implemented and ran from 2011-2013. The Florida Node Alliance shared the "know how" for the development of the research infrastructure to implement randomized clinical trials in community programs through core and specific training modules, role-specific coaching, pairings, modeling, monitoring, and feedback. The technology transfer process was bi-directional in nature in that it was informed by feedback on feasibility and cultural appropriateness for the context in which practices were implemented. The Institute, in turn, led the effort to create the national network of researchers and practitioners in Mexico and the implementation of the first trial. A collaborative model of technology transfer was useful in creating a Mexican researcher-provider network that is capable of changing national practice in substance abuse research and treatment. Key considerations for transnational technology transfer are presented.

Microsatellites also known as simple sequence repeats (SSRs) consist of 1-6 nucleotide long repeating units. The importance of mitochondrial SSRs (mtSSRs) in fields like population genetics, plant phylogenetics and genome mapping motivated us to develop MitoSatPlant, a repository of plant mtSSRs. It contains information for perfect, imperfect and compound SSRs mined from 92 mitochondrial genomes of green plants, available at NCBI (as of 1 Feb 2014). A total of 72,798 SSRs were found, of which PCR primers were designed for 72,495 SSRs. Among all sequences, tetranucleotide repeats (26,802) were found to be most abundant whereas hexanucleotide repeats (2751) were detected with least frequency. MitoSatPlant was developed using SQL server 2008 and can be accessed through a front end designed in ASP.Net. It is an easy to use, user-friendly database and will prove to be a useful resource for plant scientists. To the best of our knowledge MitoSatPlant is the only database available for plant mtSSRs and can be freely accessed at http://compubio.in/mitosatplant/.

Opioid Addiction and Abuse in Primary Care Practice: A Comparison of Methadone and Buprenorphine as Treatment Options

Science.gov (United States)

Bonhomme, Jean; Shim, Ruth S.; Gooden, Richard; Tyus, Dawn; Rust, George

2014-01-01

Opioid abuse and addiction have increased in frequency in the United States over the past 20 years. In 2009, an estimated 5.3 million persons used opioid medications nonmedically within the past month, 200 000 used heroin, and approximately 9.6% of African Americans used an illicit drug. Racial and ethnic minorities experience disparities in availability and access to mental health care, including substance use disorders. Primary care practitioners are often called upon to differentiate between appropriate, medically indicated opioid use in pain management vs inappropriate abuse or addiction. Racial and ethnic minority populations tend to favor primary care treatment settings over specialty mental health settings. Recent therapeutic advances allow patients requiring specialized treatment for opioid abuse and addiction to be managed in primary care settings. The Drug Addiction Treatment Act of 2000 enables qualified physicians with readily available short-term training to treat opioid-dependent patients with buprenorphine in an office-based setting, potentially making primary care physicians active partners in the diagnosis and treatment of opioid use disorders. Methadone and buprenorphine are effective opioid replacement agents for maintenance and/or detoxification of opioid-addicted individuals. However, restrictive federal regulations and stigmatization of opioid addiction and treatment have limited the availability of methadone. The opioid partial agonist-antagonist buprenorphine/naloxone combination has proven an effective alternative. This article reviews the literature on differences between buprenorphine and methadone regarding availability, efficacy, safety, side-effects, and dosing, identifying resources for enhancing the effectiveness of medication-assisted recovery through coordination with behavioral/psychological counseling, embedded in the context of recovery-oriented systems of care.

Smith, Russell; Wachal, Jocelyn

2000-01-01

The Nebraska SATS project is a state-level component of NASA's Small Aircraft Transportation System (SATS). During the next several years the project will examine several different factors affecting SATS implementation in Nebraska. These include economic and taxation issues, public policy issues, airport planning processes, information dissemination strategies, and systemic change factors. This background paper profiles the general aviation system in Nebraska. It is written to provide information about the "context" within which SATS will be pursued. The primary focus is thus on describing and providing background information about the current situation. A secondary focus is on drawing general conclusions about the ability of the current system to incorporate the types of changes implied by SATS. First, some brief information on the U.S. aviation system is provided. The next two sections profile the current general aviation aircraft and pilot base. Nebraska's system of general aviation airports is then described. Within this section of the paper, information is provided on the different types of general aviation airports in Nebraska, airport activity levels and current infrastructure. The fourth major section of the background paper looks at Nebraska's local airport authorities. These special purpose local governments oversee the majority of the general aviation airports in the state. Among the items examined are total expenditures, capital expenditures and planning activities. Next, the paper provides background information on the Nebraska Department of Aeronautics (NDA) and recent Federal funding for general aviation in Nebraska. The final section presents summary conclusions.

Full Text Available The aim of this research is to determine the specifics of opiate addiction in women in our environment, so as to create a specific plan of action in preventing and treatment opiate addiction in women based on the conducted description and results analysis. The sample consists of 32 examinees. Sociodempgraphic questionnaire and widely applied ASI structured interview (McLellan, Cacciola, 1982 were used. The results are in accordance with foreign research. 62.5% of opiate addicted women live with someone who is a drug addict, either as a family member or a partner. 40.6% of the examinees were physically abused, 21.9% were sexually abused as well, and 43.7% were positive for HCV. Positive criminal status and doing illegal business were present in 56% of the examinees. 56.3% of the examinees reported depression, while 84.4% are anxious. 65.6% are unemployed. Research results indicate some significant specifics of opiate addiction in women, with regard to which valuable recommendations for prevention and treatment can be made in our environment. Prevention and treatment must be multidisciplinary with the emphasis on the preserved capacities and the development of positive behavior in opiate addicted women.

This study used mixed methods to explore youth attitudes about recovery-related needs and important drug-avoidance behaviors after treatment. Focus groups were conducted with 118 substance using youth in treatment (four residential and 10 outpatient settings) throughout Los Angeles County. The average age was 17.4 (SD = 2.9); 78.3% were male, 66.1% Latino; and most were in treatment for primary marijuana (40.9%) or methamphetamine (30.4%) abuse. Quantitatve results from the drug-avoidance activity survey identified the following factors youth rated as important to their recovery after treatment: lifestyle improvement activities (95.7%); changing personal drug behaviors (89.6%); drug environment/culture change activities (82.5%); with the least important being therapeutic activities (78.5%). Qualitative findings from focus groups that asked what youth think are important for recovery programs to address after treatment revealed the following four areas: (1) recovery promotion to developmentally appropriate activities (95%); (2) facilitating the use of coping skills to deal with stress (85%); (3) offering alternative recovery support options (not just abstinence only) (75%); and (4) continuing to provide substance use education (65%). Findings highlight essential aspects of recovery in terms of need and drug-avoidance behaviors considered important to youth in treatment. Such information will help to better address clinical and recovery support models aimed at relapse prevention to ensure that the perceived problems of substance-abusing youth are adequately met.

Soil aquifer treatment using advanced primary effluent

KAUST Repository

Sharma, Saroj K.; Hussen, Mustefa; Amy, Gary L.

2011-01-01

Soil aquifer treatment (SAT) using primary effluent (PE) is an attractive option for wastewater treatment and reuse in many developing countries with no or minimal wastewater treatment. One of the main limitations of SAT of PE is rapid clogging of the infiltration basin due to high suspended solid concentrations. Some pre-treatment of PE before infiltration is likely to reduce this limitation, improve performance of SAT and help to implement this technology effectively. The effects of three pre-treatment options namely sedimentation (SED), coagulation (COAG) and horizontal roughing filtration (HRF) on SAT were analyzed by conducting laboratory-scale batch and soil column experiments. The sedimentation and coagulation pre-treatments led to less head loss development and reduction of clogging effect. The head loss development in soil column using PE + COAG and PE + SED was reduced by 85 and 72%, respectively, compared to PE alone without any pretreatment. The overall dissolved organic carbon (DOC) removal of pre-treatments and soil column collectively were 34, 44, 51 and 43.5% for PE without any pre-treatment, PE + SED, PE+ COAG and PE + HRF, respectively. Coagulation pre-treatment of PE was found to be the most effective option in terms of suspended solids, DOC and nitrogen removal. Sedimentation pre-treatment of PE could be attractive where land is relatively less expensive for the construction of sedimentation basins. © IWA Publishing 2011.

Touchscreen Sustained Attention Task (SAT) for Rats.

Bangasser, Debra A; Wicks, Brittany; Waxler, David E; Eck, Samantha R

2017-09-15

Sustained attention is the ability to monitor intermittent and unpredictable events over a prolonged period of time. This attentional process subserves other aspects of cognition and is disrupted in certain neurodevelopmental, neuropsychiatric, and neurodegenerative disorders. Thus, it is clinically important to identify mechanisms that impair and improve sustained attention. Such mechanisms are often first discovered using rodent models. Therefore, several behavior procedures for testing aspects of sustained attention have been developed for rodents. One, first described by McGaughy and Sarter (1995), called the sustained attention task (SAT), trains rats to distinguish between signal (i.e., brief light presentation) and non-signal trials. The signals are short and thus require careful attention to be perceived. Attentional demands can be increased further by introducing a distractor (e.g., flashing houselight). We have modified this task for touchscreen operant chambers, which are configured with a touchscreen on one wall that can present stimuli and record responses. Here we detail our protocol for SAT in touchscreen chambers. Additionally, we present standard measures of performance in male and female Sprague-Dawley rats. Comparable performance on this task in both sexes highlights its use for attention studies, especially as more researchers are including female rodents in their experimental design. Moreover, the easy implementation of SAT for the increasingly popular touchscreen chambers increases its utility.

This pilot study compared the pharmacologic treatment history and clinical outcomes observed in pediatric outpatients with psychiatric disorders exposed to drugs of abuse in utero to those of an age-matched, sex-matched and psychiatric disorder-matched, non-drug-exposed group. In this matched cohort study, medical records of children treated at an academic, child and adolescent psychiatry outpatient clinic were reviewed. Children with caregiver-reported history of prenatal drug exposure were compared with a non-drug-exposed control group being cared for by the same providers. Patients were rated with the Clinical Global Impressions-Severity scale (CGI-S) throughout treatment. The changes in pre-treatment and post-treatment CGI-S scores and the total number of medication trials were determined between groups. The drug-exposed group (n = 30) had a higher total number of lifetime medication trials compared with the non-drug-exposed group (n = 28) and were taking significantly more total medications, at their final assessment. Unlike the non-drug-exposed group, the drug-exposed group demonstrated a lack of clinical improvement. These results suggest that in utero drug-exposed children may be more treatment-refractory to or experience greater side effects from the pharmacologic treatment of psychiatric disorders than controls, although we cannot determine if early environment or drugs exposure drives these findings.

Mursaleen, Leah R; Stamford, Jonathan A

2016-01-04

The term "drug of abuse" is highly contextual. What constitutes a drug of abuse for one population of patients does not for another. It is therefore important to examine the needs of the patient population to properly assess the status of drugs of abuse. The focus of this article is on the bidirectional relationship between patients and drug abuse. In this paper we will introduce the dopaminergic systems of the brain in Parkinson's and the influence of antiparkinsonian drugs upon them before discussing this synergy of condition and medication as fertile ground for drug abuse. We will then examine the relationship between drugs of abuse and Parkinson's, both beneficial and deleterious. In summary we will draw the different strands together and speculate on the future merit of current drugs of abuse as treatments for Parkinson's disease. Copyright © 2015 Elsevier Inc.

Family treatment for bipolar disorder and substance abuse in late adolescence.

Science.gov (United States)

Miklowitz, David J

2012-05-01

The initial onset of bipolar disorder occurs in childhood or adolescence in about 50% of patients. Early-onset forms of the disorder have a poorer prognosis than adult-onset forms and are frequently characterized by comorbid substance abuse. Clinical trials research suggests that family psychoeducational approaches are effective adjuncts to medication in stabilizing the symptoms of bipolar disorder in adults and youth, although their efficacy in patients with comorbid substance use disorders has not been systematically investigated. This article describes the family-focused treatment (FFT) of a late adolescent with bipolar disorder and polysubstance dependence. The treatment of this patient and family required adapting FFT to consider the family's structure, dysfunctional alliance patterns, and unresolved conflicts from early in the family's history. The case illustrates the importance of conducting manual-based behavioral family treatments with a psychotherapeutic attitude, including addressing unstated emotional conflicts and resistances that may impede progress. © 2012 Wiley Periodicals, Inc.

Personal networks of women in residential and outpatient substance abuse treatment.

Kim, HyunSoo; Tracy, Elizabeth; Brown, Suzanne; Jun, MinKyoung; Park, Hyunyong; Min, Meeyoung; McCarty, Chris

This study compared compositional, social support, and structural characteristics of personal networks among women in residential (RT) and intensive outpatient (IOP) substance abuse treatment. The study sample included 377 women from inner-city substance use disorder treatment facilities. Respondents were asked about 25 personal network members known within the past 6 months, characteristics of each (relationship, substance use, types of support), and relationships between each network member. Differences between RT women and IOP women in personal network characteristics were identified using Chi-square and t -tests. Compared to IOP women, RT women had more substance users in their networks, more network members with whom they had used substances and fewer network members who provided social support. These findings suggest that women in residential treatment have specific network characteristics, not experienced by women in IOP, which may make them more vulnerable to relapse; they may therefore require interventions that target these specific network characteristics in order to reduce their vulnerability to relapse.

Over the past 20 years, satellite radar altimetry has shown its ability to revolutionize our understanding of the ocean and climate. These advances were mainly limited to ice-free regions, leaving aside large portions of Polar Regions. Launched in 2010, the polar-orbiting CryoSat Satellite was designed to measure the changes in the thickness of polar sea ice and the elevation of the ice sheets and mountain glaciers. To reach this goal, the CryoSat products have to meet the highest performance, through constant improvements of the associated Instrument Processing Facility. Since April 2015, the CryoSat ice products are generated with the Baseline C; which represents a major processor upgrade. Several improvements have been implemented belong this new Baseline, such as SAR retracker optimized for Freeboard retrieval and a coarse slant correction, which is applied directly on the stack data in conjunction with the window delay alignment. The resulting waveforms show more power and the trailing edge is modified, leading to improved L2 geophysical parameters. This paper provides an overview of the CryoSat data characteristics, assessment and exploitation over Polar Regions. In this respect, new science-oriented diagnostics have been implemented to thoroughly understand the signatures within the altimeter signals over sea-ice and land ice areas, to validate the data and therefore propose potential way of improvements for next CryoSat processing Baselines.

Morton, Cory M.; Simmel, Cassandra; Peterson, N. Andrew

2014-01-01

This study investigates the relationship between concentrations of on- and off-premises alcohol outlets and rates of child abuse and neglect. Additionally, the study seeks to locate protective features of a neighborhood's built environment by investigating the potentially moderating role that access to substance abuse treatment and prevention services plays in the relationship between alcohol outlet density and child maltreatment. Using a cross-sectional design, this ecological study utilized data from 163 census tracts in Bergen County, New Jersey, on reports of child abuse and neglect, alcohol outlets, substance abuse treatment and prevention facilities, and the United States Census to investigate the linkages between socioeconomic structure, alcohol availability, and access to substance abuse service facilities on rates of child abuse and neglect. Findings indicate areas with a greater concentration of on-premises alcohol outlets (i.e., bars) had higher rates of child neglect, and those with easier access to substance abuse services had lower rates of neglect, controlling for neighborhood demographic and socioeconomic structure. Additionally, the relationship between on-premises alcohol outlet density and rates of child neglect was moderated by the presence of substance abuse service facilities. A greater concentration of off-premises outlets (i.e., liquor stores) was associated with lower rates of physical abuse. Findings suggest that the built environment and socioeconomic structure of neighborhoods have important consequences for child well-being. The implications for future research on the structural features of neighborhoods that are associated with child well-being are discussed. PMID:24529493

Electrospray Thrusters for Attitude Control of a 1-U CubeSat

Science.gov (United States)

Timilsina, Navin

With a rapid increase in the interest in use of nanosatellites in the past decade, finding a precise and low-power-consuming attitude control system for these satellites has been a real challenge. In this thesis, it is intended to design and test an electrospray thruster system that could perform the attitude control of a 1-unit CubeSat. Firstly, an experimental setup is built to calculate the conductivity of different liquids that could be used as propellants for the CubeSat. Secondly, a Time-Of-Flight experiment is performed to find out the thrust and specific impulse given by these liquids and hence selecting the optimum propellant. On the other hand, a colloidal thruster system for a 1-U CubeSat is designed in Solidworks and fabricated using Lathe and CNC Milling Machine. Afterwards, passive propellant feeding is tested in this thruster system. Finally, the electronic circuit and wireless control system necessary to remotely control the CubeSat is designed and the final testing is performed. Among the propellants studied, Ethyl ammonium nitrate (EAN) was selected as the best propellant for the CubeSat. Theoretical design and fabrication of the thruster system was performed successfully and so was the passive propellant feeding test. The satellite was assembled for the final experiment but unfortunately the microcontroller broke down during the first test and no promising results were found out. However, after proving that one thruster works with passive feeding, it could be said that the ACS testing would have worked if we had performed vacuum compatibility tests for other components beforehand.

Quantum communication is a prime space technology application and offers near-term possibilities for long-distance quantum key distribution (QKD) and experimental tests of quantum entanglement. However, there exists considerable developmental risks and subsequent costs and time required to raise the technological readiness level of terrestrial quantum technologies and to adapt them for space operations. The small-space revolution is a promising route by which synergistic advances in miniaturization of both satellite systems and quantum technologies can be combined to leap-frog conventional space systems development. Here, we outline a recent proposal to perform orbit-to-ground transmission of entanglement and QKD using a CubeSat platform deployed from the International Space Station (ISS). This ambitious mission exploits advances in nanosatellite attitude determination and control systems (ADCS), miniaturised target acquisition and tracking sensors, compact and robust sources of single and entangled photons, and high-speed classical communications systems, all to be incorporated within a 10 kg 6 litre mass-volume envelope. The CubeSat Quantum Communications Mission (CQuCoM) would be a pathfinder for advanced nanosatellite payloads and operations, and would establish the basis for a constellation of low-Earth orbit trusted-nodes for QKD service provision.

Emirates Institution for Advanced Science and Technology (EIAST) was established by the Dubai Government in 2006. After three years of working together with Satrec Initiative (South Korea), EIAST was able to launch DubaiSat-1 on the 29th of July 2009. Building on the success of DubaiSat-1 and the roll out of the knowledge transfer program, UAE engineers were involved in almost 70% of the total build and design of DubaiSat-2. Targeting the commercial market, DubaiSat-2 was launched on the 21st of November 2013 for capturing 1-meter resolution images. The 1st Cal/Val phase was the most critical phase in the satellite life-time, where most of the initial measurements took place. This phase extended over the period of 25/11/2013 till 12/12/2013. Moreover, this phase included most of the relative calibration tasks, color balancing and band matching. 2nd Cal/Val phase included most of the debugging and the pointing accuracy calibration tests. This phase extended over the period of 11/02/2014 till 09/03/2014. This phase emphasized on the calibration of the pointing accuracy. The 3rd Cal/Val phase included fine tuning for the Gyro system to further increase the stability of the satellite and thus improve the pointing accuracy. Moreover, new techniques were implemented to the Pan-Sharpening and to the MTF compensation procedures to enhance the final product. This phase extended over the period of 04/05/2014 till 21/05/2014.

Full Text Available Substance abuse and dependence among the employed have massive cost implications for South Africa. Employers are legally obliged to provide opportunities for the treatment of substance dependence before dismissal is considered. Problem areas are the following: inadequate identification of employees with substance-abuse problems, infrequent treatment referrals, and overlooking of substance abuse in the workplace. This article attempts to address these issues by providing an overview of literature dealing with the problem of substance abuse and dependence in the workplace. Addressing this problem calls for specialist intervention measures, which are discussed in the article.

Nilsson, Maria; Sonne, Charlotte

2013-04-01

Wernicke-Korsakoff syndrome is a condition with high morbidity and mortality and occurs as a consequence of thiamine deficiency. Clinical symptoms are often ambiguous and post-mortem examinations show that the syndrome is underdiagnosed and probably undertreated. There is sparse clinical evidence concerning optimal dosage and duration of treatment. This article reviews the current literature and concludes that all patients with a history of alcohol abuse should be treated with high dosage IV thiamine for an extended period of time, albeit further research is needed.

Este trabalho centra-se em atividades na fase de pré-lançamento do satélite COROT, da agência espacial francesa (CNES), a ser lançado em 2005. O satélite será dedicado à sismologia estelar e à procura de exoplanetas. Nosso programa de trabalho centra-se em dois pontos principais: (1) efetuar uma procura detalhada nos campos COROT de alvos astrofísicos de especial interesse; (2) participar das análises espectroscópicas prévias de alvos selecionados para determinação de parâmetros físicos das estrelas com a maior precisão possível. Na presente etapa, priorizou-se o primeiro ponto do projeto. Foi feito um levantamento geral dos objetos astrofísicos encontrados nos dois campos de observação, centrados em 06H50M e 18H50M, com raios de 10 minutos. Concluiu-se que as estrelas B-Be deverão ser observadas no campo sismológico, enquanto que as anãs brancas deverão sê-lo no campo exoplanetário. Objetos a serem observados foram escolhidos de forma a estarem próximos de alvos principais dos programas centrais do satélite. Paralelamente, estudos e pesquisas bibliográficas foram feitos para compreender os assuntos de interesse principal, ou seja, as pulsações não-radiais de estrelas Ob-Be

Full Text Available Background: In the recent decades increasing number of women have been seeking deaddiction services. Despite that the report data is very limited from India. Objectives: The present research aimed to study the demographic and clinical profile of women seeking deaddiction treatment at a tertiary care center in North India. Materials and Methods: Retrospective structured chart review of 100 women substance abusers seeking treatment at a deaddiction center between September 1978 and December 2011. Results: A typical case was of 36.3 years age, married (65%, urban (61%, nuclear family (59% based housewife (56%, with good to fair social support (69%. The commonest substance of abuse was tobacco (60%, followed by opioids (27%, alcohol (15%, and benzodiazepines (13%. The common reasons for initiation of substance use were to alleviate frustration or stress (49% and curiosity (37%. Family history of drug dependence (43%, comorbidity (25%, and impairments in health (74%, family (57%, and social domains (56% were common. Only a third of the sample paid one or more follow visit, and of those 58% were abstinent at the last follow-up. Significant predictors identified were being non-Hindu and higher educational years for abstinent status at follow-up. Conclusion: The common substances of abuse were tobacco, opioids, and alcohol and benzodiazepines; and family history of drug abuse and comorbidity were common. The follow-up and outcome were generally poor. This profile gives us some clues to address a hidden health problem of the community.

Evidence for the effectiveness of linezolid in neurosurgical infections (NSIs) is growing. The comfortable oral dosage and tolerance of linezolid opens the possibility for sequential antimicrobial treatment (SAT) in stable patients after a period of intravenous treatment. To evaluate the efficacy and safety of SAT with oral linezolid in patients with NSI and to analyse the cost implications, an observational, non-comparative, prospective cohort study was conducted on clinically stable consecutive adult patients at the Neurosurgical Service. Following intravenous treatment, patients were discharged with SAT with oral linezolid. A total of 77 patients were included. The most common NSIs were: 41 surgical wound infections, 20 subdural empyemas, 18 epidural abscesses, and 16 brain abscesses. Forty-four percent of patients presented two or more concomitant NSIs. Aetiological agents commonly isolated were: Propionibacterium acnes (36 %), Staphylococcus aureus (23 %), Staphylococcus epidermidis (21 %) and Streptococcus spp. (13 %). The median duration of the SAT was 15 days (range, 3-42). The SAT was interrupted in five cases due to adverse events. The remainder of the patients were cured at the end of the SAT. A total of 1,163 days of hospitalisation were saved. An overall cost reduction of €516,188 was attributed to the SAT. Eight patients with device infections did not require removal of the device, with an additional cost reduction of €190,595. The mean cost saving per patient was €9,179. SAT with linezolid was safe and effective for the treatment of NSI. SAT reduces hospitalisation times, which means significant savings of health and economic resources.

Different immunotherapeutic approaches are in the pipeline for the treatment of drug dependence. "Drug vaccines" aim to induce the immune system to produce antibodies that bind to drugs and prevent them from inducing rewarding effects in the brain. Drugs of abuse currently being tested using these new approaches are opioids, nicotine, cocaine, and methamphetamine. In human clinical trials, "cocaine and nicotine vaccines" have been shown to induce sufficient antibody levels while producing few side effects. Studies in humans, determining how these vaccines interact in combination with their target drug, are underway. However, although vaccines can become a reasonable treatment option for drugs of abuse, there are several disadvantages that must be considered. These include i) great individual variability in the formation of antibodies, ii) the lack of protection against a structurally dissimilar drug that produces the same effects as the drug of choice, and iii) the lack of an effect on the drug desire that may predispose an addict to relapse. In addition, a comprehensive overview of several crucial ethical issues has not yet been widely discussed in order to have not only a biological approach to immunotherapy of addiction. Overall, immunotherapy offers a range of possible treatment options: the pharmacological treatment of addiction, the treatment of overdoses, the prevention of toxicity to the brain or the heart, and the protection of the fetus during pregnancy. So far, the results obtained from a small-scale experiment using vaccines against cocaine and nicotine suggest that a number of important technical challenges still need to be overcome before such vaccines can be approved for clinical use.

Galanter, M; Keller, D S; Dermatis, H; Egelko, S

2000-01-01

This report examines the impact of managed care (MC) and related developments on substance abuse treatment, and evaluates how it has been associated with a decline in the availability of proper treatment for many addicted patients. A trend toward carve-out and for-profit MC organizations is associated with lower financial incentives for intensive treatment than in earlier staff-model and not-for-profit MC organizations. The value of substance abuse insurance coverage has declined by 75% between 1988 and 1998 for employees of mid-to large-size companies, compared with only an 11.5% decline for general health insurance. The shift towards MC has also been associated with a drastic reduction in frequency and duration of inpatient hospitalization, and there is no clear evidence that this reduction has been offset by a corresponding increase in outpatient support. In a survey of physicians treating addiction, the majority felt that MC had a negative impact on detoxification and rehabilitation, and on their ethical practice of addiction medicine.

2015-09-01

Full Text Available Objective: This study was an attempt to compare cognitive functioning in substance abusers and addicts under methadone treatment with normal individuals. Method: The current study was a causal-comparative one. The statistical population of this research consisted of all male substance abusers who had referred to addiction treatment centers of Khoy city in 2013. The total of 40 addicts under methadone treatment, 40 active drug users, and 40 non-addicts were selected as the participants of this study via convenience sampling method. Wisconsin Card Sorting Test and Wechsler Memory Scale were administered to the three groups for data collection purposes. Results: The results showed that the substance abusers’ scores in Wisconsin card sorting test and Wechsler memory scale were significantly different from those of addicts under methadone treatment and normal individuals. In the same way, there was a significant difference between addicts under methadone treatment and normal individuals in terms of cognitive function however, there was no significant difference between these two groups in terms of perseveration error. Conclusion: It can be concluded that chronic use of psychoactive substances causes damage to multiple brain regions such as prefrontal cortex and hippocampus and, thereby, it leads to cognitive malfunctioning in these areas.

Novel approaches for the treatment of psychostimulant and opioid abuse - focus on opioid receptor-based therapies.

Science.gov (United States)

Bailey, Chris P; Husbands, Stephen M

2014-11-01

Psychostimulant and opioid addiction are poorly treated. The majority of abstinent users relapse back to drug-taking within a year of abstinence, making 'anti-relapse' therapies the focus of much current research. There are two fundamental challenges to developing novel treatments for drug addiction. First, there are three key stimuli that precipitate relapse back to drug-taking: stress, presentation of drug-conditioned cue, taking a small dose of drug. The most successful novel treatment would be effective against all three stimuli. Second, a large number of drug users are poly-drug users: taking more than one drug of abuse at a time. The ideal anti-addiction treatment would, therefore, be effective against all classes of drugs of abuse. In this review, the authors discuss the clinical need and animal models used to uncover potential novel treatments. There is a very broad range of potential treatment approaches and targets currently being examined as potential anti-relapse therapies. These broadly fit into two categories: 'memory-based' and 'receptor-based' and the authors discuss the key targets here within. Opioid receptors and ligands have been widely studied, and research into how different opioid subtypes affect behaviours related to addiction (reward, dysphoria, motivation) suggests that they are tractable targets as anti-relapse treatments. Regarding opioid ligands as novel 'anti-relapse' medication targets, research suggests that a 'non-selective' approach to targeting opioid receptors will be the most effective.

Neighborhood alcohol outlet density and rates of child abuse and neglect: moderating effects of access to substance abuse services.

Morton, Cory M; Simmel, Cassandra; Peterson, N Andrew

2014-05-01

This study investigates the relationship between concentrations of on- and off-premises alcohol outlets and rates of child abuse and neglect. Additionally, the study seeks to locate protective features of a neighborhood's built environment by investigating the potentially moderating role that access to substance abuse treatment and prevention services plays in the relationship between alcohol outlet density and child maltreatment. Using a cross-sectional design, this ecological study utilized data from 163 census tracts in Bergen County, New Jersey, on reports of child abuse and neglect, alcohol outlets, substance abuse treatment and prevention facilities, and the United States Census to investigate the linkages between socioeconomic structure, alcohol availability, and access to substance abuse service facilities on rates of child abuse and neglect. Findings indicate areas with a greater concentration of on-premises alcohol outlets (i.e., bars) had higher rates of child neglect, and those with easier access to substance abuse services had lower rates of neglect, controlling for neighborhood demographic and socioeconomic structure. Additionally, the relationship between on-premises alcohol outlet density and rates of child neglect was moderated by the presence of substance abuse service facilities. A greater concentration of off-premises outlets (i.e., liquor stores) was associated with lower rates of physical abuse. Findings suggest that the built environment and socioeconomic structure of neighborhoods have important consequences for child well-being. The implications for future research on the structural features of neighborhoods that are associated with child well-being are discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

Tapentadol, a Schedule II opioid with a combination of µ-opioid activity and norepinephrine reuptake inhibition, is used for the management of moderate to severe acute and chronic pain. Its dual mechanism of action is thought to reduce opioid-related side effects that can complicate pain management. Since approval, tapentadol has been tracked across multiple outcomes suggesting abuse liability, and a pattern of relatively low, although not absent, abuse liability has been found. This retrospective cohort study further details the abuse liability of tapentadol as an active pharmaceutical ingredient (API) when immediate-release as well as extended-release formulations were on the market together (fourth quarter of 2011 to second quarter of 2016). Tapentadol (API) was compared with tramadol, hydrocodone, morphine, oxycodone, hydromorphone, and oxymorphone across Poison Center, Drug Diversion, and Treatment Center Programs Combined data streams from the Researched Abuse, Diversion and Addiction-Related Surveillance system. Findings suggest the public health burden related to tapentadol to date is low, but present. Event rates of abuse per population-level denominators were significantly lower than all other opioids examined. However, when adjusted for drug availability, event rates of abuse were lower than most Schedule II opioids studied, but were not the lowest. Disentangling these 2 sets of findings further by examining various opioid formulations, such as extended-release and the role of abuse-deterrent formulations, is warranted. This article presents the results from an examination of tapentadol API across the Researched Abuse, Diversion and Addiction-Related Surveillance System: a broad and carefully designed postmarketing mosaic. Data to date from Poison Center, Drug Diversion, and Treatment Centers combined suggest a low, but present public health burden related to tapentadol. Copyright © 2018. Published by Elsevier Inc.

Tracking Dynamic Northern Surface Water Changes with High-Frequency Planet CubeSat Imagery

Directory of Open Access Journals (Sweden)

Sarah W. Cooley

2017-12-01

Full Text Available Recent deployments of CubeSat imagers by companies such as Planet may advance hydrological remote sensing by providing an unprecedented combination of high temporal and high spatial resolution imagery at the global scale. With approximately 170 CubeSats orbiting at full operational capacity, the Planet CubeSat constellation currently offers an average revisit time of <1 day for the Arctic and near-daily revisit time globally at 3 m spatial resolution. Such data have numerous potential applications for water resource monitoring, hydrologic modeling and hydrologic research. Here we evaluate Planet CubeSat imaging capabilities and potential scientific utility for surface water studies in the Yukon Flats, a large sub-Arctic wetland in north central Alaska. We find that surface water areas delineated from Planet imagery have a normalized root mean square error (NRMSE of <11% and geolocation accuracy of <10 m as compared with manual delineations from high resolution (0.3–0.5 m WorldView-2/3 panchromatic satellite imagery. For a 625 km2 subarea of the Yukon Flats, our time series analysis reveals that roughly one quarter of 268 lakes analyzed responded to changes in Yukon River discharge over the period 23 June–1 October 2016, one half steadily contracted, and one quarter remained unchanged. The spatial pattern of observed lake changes is heterogeneous. While connections to Yukon River control the hydrologically connected lakes, the behavior of other lakes is complex, likely driven by a combination of intricate flow paths, underlying geology and permafrost. Limitations of Planet CubeSat imagery include a lack of an automated cloud mask, geolocation inaccuracies, and inconsistent radiometric calibration across multiple platforms. Although these challenges must be addressed before Planet CubeSat imagery can achieve its full potential for large-scale hydrologic research, we conclude that CubeSat imagery offers a powerful new tool for the study and

Drug abuse in the world quite astonish and tend to increase. The increase and decrease on the number of drug abusers showed a pattern of spread that had the same characteristics with patterns of spread of infectious disease. The susceptible infected removed (SIR) and susceptible exposed infected removed (SEIR) epidemic models for infectious disease was developed to study social epidemic. In this paper, SEIR model for disease epidemic was developed to study drug abuse epidemic with rehabilitation treatment. The aims of this paper were to analogize susceptible exposed infected isolated recovered (SEIIrR) model on the drug abusers, to determine solutions of the model, to determine equilibrium point, and to do simulation on β. The solutions of SEIIrR model was determined by using fourth order of Runge-Kutta algorithm, equilibrium point obtained was free-drug equilibrium point. Solutions of SEIIrR showed that the model was able to suppress the spread of drug abuse. The increasing value of contact rate was not affect the number of infected individuals due to rehabilitation treatment.

The economic impact of alcohol abuse and alcoholism.

Burke, T R

1988-01-01

The economic effects of alcohol abuse are as damaging to the nation as the health effects, affecting the family, the community, and persons of all ages. Underaged drinking is interfering with children's development, affecting the nation's ability to respond to economic challenge in the future. The college aged may be the most difficult to educate about alcohol abuse because of drinking patterns established at an early age and susceptibility to advertising inducements. Health care costs for families with an alcoholic member are twice those for families without one, and up to half of all emergency room admissions are alcohol related. Fetal alcohol syndrome is one of the top three known causes of birth defects, and is totally preventable. Alcohol abuse and alcoholism are estimated to have cost the nation $117 billion in 1983, while nonalcoholic drug abuse that year cost $60 billion. Costs of alcohol abuse are expected to be $136 billion a year by 1990, mostly from lost productivity and employment. Between 6 and 7 million workers are alcoholic, with an undetermined loss of productivity, profits, and competitiveness of American business. Alcohol abuse contributes to the high health care costs of the elderly beneficiaries of Federal health financing programs. Heavily affected minorities include blacks, Hispanics, and Native Americans. Society tends to treat the medical and social consequences of alcohol abuse, rather than its causes. Although our experience with the consequences of alcohol abuse is greater than that for any other drug, public concern for its prevention and treatment is less than for other major illnesses or abuse of other drugs. Alcohol abuse is a problem being given high priority within the Department in an effort to create a national agenda on the issue and to try to impart a greater sense of urgency about the problems. Ways are being explored to integrate alcoholism activities into more Departmental programs. Employee assistance programs for alcohol

High satisfaction with iron chelation is a major determinant for adherence to ICT in beta-thalassaemia major (β-TM) patients. In this study, a new tool to assess different domains of satisfaction for available forms of ICT was developed and validated. The impact of patients' satisfaction with ICT has been tested. Items were generated via focus groups and a preliminary version with 24 items (ICT-Sat) with an additional item for treatment preference and a knowledge questionnaire (KQ) was developed. 170 β-TM patients from three Thalassaemia centers in Egypt, aged 2-32 years received three questionnaires to fill in; the new ICT-Sat, a KQ, and a previously validated tool for satisfaction with ICT (SICT) and retested 4-6 weeks later to ensure re-test reliability. Type of chelation, drug related adverse events, compliance with ICT, and serum ferritin level (SF) during the year prior to the study as well as available cardiac T2*data were recorded. One hundred and fifty two β-TM patients completed all questionnaires; median age was 12 years. The final 15 remaining ICT-Sat items, yielding to four domain scores, explained 70.6% of the total variance. The "perceived effectiveness" and "fear and worries" domains of the ICT-Sat correlated significantly with the domains "perceived effectiveness" and "acceptance" of the SICT. Patients treated with oral ICT were more satisfied with perceived effectiveness, and their side effects. A new clinically based ICT-Sat tool was developed and revealed good psychometric characteristics. Adherence to ICT was better correlated with "perceived effectiveness" and SF level.

Hoffman, Kim A.; Green, Carla A.; Ford, James H.; Wisdom, Jennifer P.; Gustafson, David H.; McCarty, Dennis

2012-01-01

Process and quality improvement techniques have been successfully applied in health care arenas, but efforts to institute these strategies in alcohol and drug treatment are underdeveloped. The Network for the Improvement of Addiction Treatment (NIATx) teaches participating substance abuse treatment agencies to use process improvement strategies to increase client access to, and retention in, treatment. NIATx recommends five principles to promote organizational change: 1) Understand and involve the customer; 2) Fix key problems; 3) Pick a powerful change leader; 4) Get ideas from outside the organization; and 5) Use rapid-cycle testing. Using case studies, supplemented with cross-agency analyses of interview data, this paper profiles participating NIATx treatment agencies that illustrate application of each principle. Results suggest that the most successful organizations integrate and apply most, if not all, of the five principles as they develop and test change strategies. PMID:22282129

 Although individualized homeopathic treatment is effective for depression in climacteric women, there is a lack of well-designed studies of its efficacy for depression in battered women or in post-traumatic stress disorder. The aim of this study was to assess the association between individualized homeopathic treatment or fluoxetine and response to depression treatment in climacteric women with high levels of domestic violence, sexual abuse or marital dissatisfaction.  One hundred and thirty-three Mexican climacteric women with moderate-to-severe depression enrolled in the HOMDEP-MENOP Study (a randomized, placebo-controlled, double-blind, double-dummy, three-arm trial, with a 6-week follow-up study) were evaluated. Domestic violence, marital dissatisfaction and sexual abuse were assessed at baseline. Response to depression treatment was defined by a decrease of 50% or more from baseline score of Hamilton scale. Association between domestic violence, sexual abuse, and marital dissatisfaction and response to depression treatment was analyzed with bivariate analysis in the three groups. Odds ratio (OR) and 95% confidence interval (CI) were calculated.  Homeopathy versus placebo had a statistically significant association with response to depression treatment after adjusting for sexual abuse (OR [95% CI]: 11.07 [3.22 to 37.96]), domestic violence (OR [95% CI]: 10.30 [3.24 to 32.76]) and marital dissatisfaction (OR [95% CI]: 8.61 [2.85 to 25.99]).  Individualized homeopathic treatment is associated with response to depression treatment in climacteric women with high levels of domestic violence, sexual abuse or marital dissatisfaction. Further studies should be conducted to evaluate its efficacy specifically for post-traumatic stress disorder in battered women. CLINICALTRIALS.

Operators of a constellation of CubeSats have to confront a number of daunting challenges that can be cost prohibitive, or operationally prohibitive, to missions that could otherwise be enabled by a satellite constellation. Challenges including operations complexity, intersatellite communication, intersatellite navigation, and time sharing tasks between satellites are all complicated by operating with the usual CubeSat size, power, and budget constraints. EDSN pioneers innovative solutions to these problems as they are presented on the nano-scale satellite platform.
