Overcoming alcohol and other drug addiction as a process of social identity transition: the social identity model of recovery (SIMOR)

Abstract In recent years, there has been an increasing focus on a recovery model within alcohol and drug policy and practice. This has occurred concurrently with the emergence of community- and strengths-based approaches in positive psychology, mental health recovery and desistance and rehabilitation from offending. Recovery is predicated on the idea of substance user empowerment and self-determination, using the metaphor of a “journey”. Previous research describing recovery journeys has pointed to the importance of identity change processes, through which the internalised stigma and status of an “addict identity” is supplanted with a new identity. This theoretical paper argues that recovery is best understood as a personal journey of socially negotiated identity transition that occurs through changes in social networks and related meaningful activities. Alcoholics Anonymous (AA) is used as a case study to illustrate this process of social identity transition. In line with recent social identity theorising, it is proposed that (a) identity change in recovery is socially negotiated, (b) recovery emerges through socially mediated processes of social learning and social control and (c) recovery can be transmitted in social networks through a process of social influence.
BIOSORPTION OF NI ( II ) FROM INDUSTRIAL EFFLUENT BY CAULERPA RACEMOSA AND ULVA LACTUCA

Environmental pollution is serious global problem; it leads research towards remediation technique by applying biological method. Marine algal treatment for the biosorption of metal is found promising technique because of its availability and low cost, it absorbs toxic metals from the waste water. The biosorption capacity of the seaweed is depend on chemical constitution of their cell wall and presence of molecules with various functional groups which interacts with metal ions. This research paper focuses on biosorption of nickel (II) by using marine algal biomass of Caulerpa racemosa and Ulva lactuca (Chlorophyceae) and study of Langmuir and Freundlich adsorption isotherms and kinetics. The study indicates both the isotherm models observed favorable; the Freundlich model indicates higher adsorption capacity of the biomass. This study shows Ulva lactuca gives higher biosorption yield as compare to Caulerpa racemosa. The kinetic study indicates the reaction follows pseudo second order model observed in both marine algal biomass. Thus, it can be used as an effective technique in heavy metal removal from the contaminated environment.
Consolidating Service Engineering Ontologies : Building Service Ontology from SOA Modeling Language (SoaML)

As a term for characterizing a process of devising a service system, the term ‘service engineering’ is still regarded as an ‘open’ research challenge due to unspecified details and conflicting perspectives. This paper presents consolidated service engineering ontologies in collecting, specifying and defining relationship between components pertinent within the context of service engineering. The ontologies are built by way of literature surveys from the collected conceptual works by collating various concepts into an integrated ontology. Two ontologies are produced: general service ontology and software service ontology. The software-service ontology is drawn from the informatics domain, while the generalized ontology of a service system is built from both a business management and the information system perspective. The produced ontologies are verified by exercising conceptual operationalization of the ontologies in adopting several service orientation features and service system patterns. The proposed ontologies are demonstrated to be sufficient to serve as a basis for a service engineering framework.
Self-Assembled Nanoparticles of Ribozymes with Poly(ethylene glycol)-b-Poly(L-lysine) Block Copolymers

Complex nanoparticle formation of poly(ethylene glycol)-b-poly(L-lysine) (PEG-b-PLL) block copolymers with ribozyme (Rzs) in an aqueous solution was studied. Nanoparticles formed from PEG-b-PLL and Rzs have about 100 nm in an effective diameter with the hydrophilic PEG segments stabilizing and surrounding the core of complexes formed between the PLL segments and Rzs. The block copolymer having a higher positive charge formed relatively smaller complex nanoparticles. The profile of the ethidum bromide (EtBr) displacement assay and images of agarose gel electrophoresis revealed the condensation of Rzs to form complex nanoparticles above a critical weight ratio, r (r: 4.0 for PEG5000-b-PLL1920 and 3.0 for PEG5000-b-PLL3840). Furthermore, the PEG-b-PLL/Rz complex nanoparticle showed high resistance against RNase attack in biological fluids.
Modeling the influence of deep water application of dispersants on the surface expression of oil: A sensitivity study

Although the effects of chemical dispersants on oil droplet sizes and ascent speeds are well-known, the fate and transport of dispersed oil droplets of different sizes under varying hydrodynamic conditions can be difficult to assess with observations alone. We used a particle tracking model to evaluate the effect of changes in droplet sizes due to dispersant application on the short-term transport and surface expression of oil released under conditions similar to those following the 3 June 2010 riser cutting during the Deepwater Horizon event. We used simulated injections of oil droplets of varying size and number under conditions associated with no dispersant application and with dispersant application at 50% and 100% efficiency. Due to larger droplet sizes in the no-dispersant scenario, all of the simulated oil reached the surface within 7 h, while only 61% and 28% of the oil reached the surface after 12 h in the 50% and 100% dispersant efficiency cases, respectively. The length of the surface slick after 6 h was 2 km in the no-dispersant case whereas there was no surface slick after 6 h in the 100% dispersant case, because the smaller oil droplets which resulted from dispersant application had not yet reached the surface. Model results suggest that the application of dispersants at the well head had the following effects: (1) less oil reached the surface in the 6-12 h after application, (2) oil had a longer residence time in the water-column, and (3) oil was more highly influenced by subsurface transport.
Balanced Anesthesia with Dexmedetomidine added Desflurane or Sevoflurane in Spinal Surgery

Objectives: Sevoflurane and desflurane inhalational anesthetics are used for fast-track neuroanesthesia. Dexmedetomidine is used to provide analgesia, sedation and hemodynamic stability. Other anesthetic and analgesic requirements decrease when dexmedetomidine is administered, thus it is an interesting option for intraoperative agent for general anesthesia. We aim to compare desflurane and sevoflurane with dexmedetomidine in the operating room (OR) and Post-Anesthesia Care Unit (PACU) by using Fast-Tract -Criteria (FTC) and Aldrete Criteria (AC) for spinal surgery patients. Methods: A double-blind study was conducted. One hundred ASA I-II patients aged 18–65 were randomly divided into two groups. Following the standard anesthesia induction, Group (D+D) (n=50) received 2–4 % desflurane + 0.2 μg/kg/h dexmedetomidine and Group (S+D) (n=50) received 1-3 % sevoflurane + 0.2 μg/kg/h dexmedetomidine in 60 % N2O for anesthesia management. Extubation times, and FTC and AC were evaluated in the OR at the 5th and 10th minutes and in PACU at the 5th, 15th and 25th minutes. P< 0.05 was considered significant. Results: Demographic features of the patients in the two groups were similar. Extubation time in Group (D+D) was shorter than that in Group (S+D) (5.9 ± 2.4 and 8.3 ± 3.9 min respectively, p=0.001). In OR at the 10th min, and in PACU at the 5th min; Group (D+D) had a higher AC score than did Group (S+D) (p=0.001), and also at the 15th min., Group (D+D) had a higher FTC (P=0.01) and AC (p=0.007) scores than did Group (S+D). In all the patients, targeted discharge points were achieved at the 25th minute in PACU Conclusions: Balanced anesthesia with desflurane / dexmedetomidine combination is superior to sevoflurane / dexmedetomidine in extubation time and time to reach an AC ≥ 9 and FTC ≥ 13 in spinal surgery.
Molecular Epidemiology and Air Pollution

The relationship between exposure to B[a]P and the level of DNA adducts and chromosomal aberrations in winter 2010 in Ostrava inhabitants was surprising, as the results did not correspond with the expected dose effect relationship. Therefore Rossner et al. [61] put forward a hypothesis about a possible adaptive response, indicating that this outcome may be affected by DNA repair. In 64 subjects from Prague and 75 subjects from Ostrava they investigated the levels of oxidative stress markers (8-oxodG, 15-F2t-IsoP, protein carbonyls) and cytogenetic parameters [F G /100, % AB.C. and acentric fragments (ace)], and their relationship with the expression of genes participating in base excision repair (BER) and non-homologous end-joining (NHEJ) by quantitative PCR. Multivariate analyses revealed that subjects living in Ostrava had increased odds of having above-median levels of XRCC5 expression (OR; 95% CI: 3.33; 1.03–10.8; q = 0.046). Above-median levels of 8-oxodG were associated with decreased levels of vitamins C (OR; 95% CI: 0.37; 0.16–0.83; p = 0.016) and E (OR; 95% CI: 0.25; 0.08–0.75; p = 0.013), which were elevated in subjects from Ostrava. They suggest that air pollution by c-PAHs affects XRCC5 expression, which probably protect subjects from Ostrava against the induction of a higher frequency of translocations; elevated vitamin C and E levels in the Ostrava subjects decrease the levels of 8-oxodG. Such changes in gene expression were not observed in the 4 subjects from Prague after 3 weeks stay in Ostrava, their reaction differed from subjects with long residence time in OSTR. of having above-median levels of XRCC5 expression (OR; 95% CI: 3.33; 1.03–10.8; q = 0.046). Above-median levels of 8-oxodG were associated with decreased levels of vitamins C (OR; 95% CI: 0.37; 0.16–0.83; p = 0.016) and E (OR; 95% CI: 0.25; 0.08–0.75; p = 0.013), which were elevated in subjects from Ostrava. They suggest that air pollution by c-PAHs affects XRCC5 icity strong correlation between B[a]P and other c-PAH content in all EOMs tested in these studies (r = 0.98; p<0.001) suggests that B[a]P may be used as an in mixtures.
Biomechanism of Abfraction Lesions

Introduction: Caries and dental trauma are mostly responsible for the loss of hard tooth tissue. However, other destructive processes that originate on the external surface and affect the teeth and cause irreversible loss to the tooth structure are also described such as erosion, abrasion, attrition and abfraction. Objective: The purpose of this study was a finite elements method study of the mechanism of abfraction formation caused by external loads. Material and methods: A two-dimensional mathematical finite elements analysis model was generated for analysis, using intact normal human mandibular canine. The finite elements are type of 2D. A denser mesh with a large number of EF was build in the area of interest in order to obtain the best replica of the tooth and the most faithful analyses of the situation. Results: As a result of the present study using simulations of different values and positions of the loads, both vertical and oblique, on a healthy tooth, it was evident that the most stress-prone area with the highest risk of mechanic damage is the cervical area of the tooth. Conclusions: Oblique loads lead to lateral flexure of the tooth and vertical loads lead to axial compression. Vertical direction of loads result in higher values of the stress in the lesionned area. The study shows that one of the possible causes of cervical lesion is the direction and magnitude of loads combined with the morphology of the tooth in question.
Time-aware collaborative ﬁtering: a review

Collaborative Filtering (CF) has been a popular research topic in the ﬁeld of recommender systems. Traditional CF algorithms rely on the assumption that data is stationary and disregards the dynamic nature of usage data. However, user preferences typically change over time, and traditional static CF algorithms do not have the ability to reﬂect these changes. In the past few years a new generation of CF algorithms has emerged that considers temporal eﬀects. This paper provides a short survey on these time-aware CF algorithms and challenges for the near future.
UnderVolt_FNN: An Energy-Efficient and Fault-Resilient Low-Voltage FPGA-based DNN Accelerator

There is continually growing interest to accelerate DNNs using FPGAs, e.g., Microsoft Catapult [3], thanks to FPGAs inherently power-efficient architecture and their capability for streaming-fashion data marshalling and computation on the massively parallel FPGA structure. However, in comparison to ASIC-based accelerators, e.g. Google TPU [2] and IBM TrueNorth [1], their energy efficiency is still a key concern. In order to bridge this gap, we propose UnderVolt FNN, a novel FPGA-based accelerator that leverages aggressive undervolting for improving the energy efficiency of DNNs in the inference phase, without compromising the inference accuracy and performance. Toward this goal, we first extensively characterize the behavior of undervolting faults on real FPGAs, and accordingly, propose a fault mitigation technique to prevent the DNNs accuracy loss. In consequence, UnderVolt FNN achieves 25.2% of the total power savings gain without compromising the DNNs accuracy and performance. We believe that the proposed technique has potential to improve the energy-efficiency of enterprise systems such as Microsoft Catapult.
Adsorption of Heavy Metals by Salvinia Biomass and Agricultural Residues

Batch adsorption experiments were performed to study adsorption potential of agricultural residues viz. rice straw, wheat straw and Salvinia plant biomass for removal of heavy metals such as Cr, Ni, and Cd. Plant materials were used in different combinations. Heavy metal removal efficiency was more at low metal concentration (35 mg/L). Salvinia biomass possessed higher efficiency for removing heavy metals such as Cr, Ni and Cd followed by a combination where three materials (rice straw, wheat straw, Salvinia biomass) were taken together in comparison to other combinations. The adsorption data fitted in Langmuir and Freundlich isotherm models.The present investigations revealed that agricultural residues such as rice straw and wheat straw along with Salvinia biomass can serve as low-cost alternative for removal of heavy metals from wastewaters.
Enhanced antioxidant enzyme activity in tissues and reduced total oxidative stress in plasma by the effect of Swietenia macrophylla king seeds in type II diabetes rats

The complications of diabetes are mainly as a result imbalance between oxidative stress and antioxidant defence. Several plant products are being reported to be effective in this condition including Swietenia macrophylla king. The aim of this study was to find out whether the aqueous extract of these seeds have any effect on the antioxidant enzyme activity in liver and kidney tissues and on the total oxidative stress in plasma in the experimental type II diabetic rats. Streptozotocin was used to induce diabetes except in the control group. The activities of the antioxidant enzymes in the tissues extracts. The activities of the antioxidant enzymes in the tissues extracts and total oxidative stress in plasma were estimated using standardized methods.The extract fed rats show significantly increased activity of superoxide dismutase (U/mg), Catalase (U/mg) and glutathione peroxidise (U/mg) in the liver (5.12±0.21, 45.03±1.19, 2.69±0.02 respectively) and kidney tissues (5.66±0.06, 89.61±0.27, 2.93±0.01, respectively) than the diabetic control animals (3.08±0.21, 33.01± 1.36, 1.94±0.08 in liver and 3.60±0.07, 40.42±1.73, 2.21±0.05 in kidney respectively). Total oxidative stress was found significantly decreased (82.5±0.05 FORT U) in the animals treated with extract compared to the diabetic controls (100±0.63 FORT U). We conclude that the extract of Swietenia macrophylla king seeds effectively reduce the oxidative stress in plasma as well as increase the antioxidant enzyme defence in the antioxidant enzyme defence in the tissues of experimental diabetic rats.
Toxicities of New Drugs for Melanoma Treatment and their Management

Adjuvant immunotherapy for stage III melanoma is mainly based on interferon-α2b (IFN-α2b) even if its efficacy is quite limited. In fact, only about the 20% of patients showed an improve‐ ment in relapse-free survival as demonstrated in randomized observation-controlled trials without a clear effect on overall survival [3]. FDA approved high-dose interleukin-2 (IL-2) for the treatment of advanced stage melanoma, on the basis of its ability to elicit durable responses in a small percentage of patients [4, 5]. However, the durable response rate is only 10-20% and toxicities associated with IL-2 are quite severe.
3D Cell Nuclear Morphology: Microscopy Imaging Dataset And Voxel-Based Morphometry Classification Results

Cell deformation is regulated by complex underlying biological mechanisms associated with spatial and temporal morphological changes in the nucleus. Quantitative analysis of changes in size and shape of nuclear structures in 3D microscopic images is important not only for investigating nuclear organization, but also for detecting and treating pathological conditions such as cancer. Multiple methods have been proposed to classify cell and nuclear morphological phenotypes in 3D, however, there is a lack of publicly available 3D data for the evaluation and comparison of such algorithms. To address this problem, we present a dataset containing a of total of 1,433 segmented nuclear and 3,282 nucleolar binary masks. We also provide a baseline evaluation of a number of popular classification algorithms using voxel-based morphometric measures. Original and derived imaging data are made publicly available for downloading on the project web-page: http://www.socr. umich.edu/projects/3d-cell-morphometry/data.html.
Observations and Predictions of Arctic Climatic Change: Potential Effects on Marine Mammals

Recent analyses have revealed trends over the past 20-30 years of decreasing sea ice extent in the Arctic Ocean coincident with warming trends. Such trends may be indicative of the polar amplifications of warming predicted for the next several decades in response to increasing atmospheric CO2. We have summarized these predictions and nonuniform patterns of arctic climate change in order to address their potential effects on marine mammals. Since recent trends in sea ice extent are nonuniform, the direct and indirect effects on marine mammals are expected to vary geographically. Changes in the extent and concentration of sea ice may alter the seasonal distributions, geographic ranges, patterns of migration, nutritional status, reproductive success, and ultimately the abundance and stock structure of some species. Ice-associated seals, which rely on suitable ice substrate for resting, pupping, and molting, may be especially vulnerable to such changes. As recent decreases in ice coverage have been more extensive in the Siberian Arctic (60 E-180 E) than in the Beaufort Sea and western sectors, we speculate that marine mammal populations in the Siberian Arctic may be among the first to experience climate-induced geographic shifts or altered reproductive capacity due to persistent changes in ice extent. Alteration in the extent and productivity of ice-edge systems may affect the density and distribution of important ice-associated prey of marine mammals, such as arctic cod, Boreogadus saida , and sympagic ("with ice") amphipods. Present climate models, however, are insufficient to predict regional ice dynamics, winds, mesoscale features, and mechanisms of nutrient resupply, which must be known to predict productivity and trophic response. Therefore, it is critical that mesoscale process-oriented studies identify the biophysical coupling required to maintain suitable prey availability and ice-associated habitat for marine mammals on regional arctic scales. Only an integrated ecosystems approach can address the complexity of factors determining reproductivity and cascading trophic dynamics in a warmer Arctic. This approach, integrated with monitoring of key indicator species (e.g., bowhead whale, ringed seal, and beluga), should be a high priority.
Relationship between HIV Positive Status Announcement and Smoking among Infected-Individuals in Bamako, Mali

Background: The announcement of HIV-positive status is a critical moment of psycho-social destabilization that can induce changes in the behavior of an individual such a beginning or increased tobacco consumption. Objective: The objective was to study the relationship between the HIV positive status announcement and smoking behavior among people living with human immunodeficiency virus (HIV) in Bamako after the discovering their status. Methods: We did a descriptive cross-sectional study over six months from January to June 2012. Data were collected by interviewing HIV infected patients in three health care centers, departments of pulmonary diseases, department of infectious and tropical diseases and the largest HIV clinic in Mali (CESAC of Bamako). All participants have signed an informed consent before the interview. Data were analyzed using Epi-Info version 7.1. 5.2 software. Results: A total of 301 HIV-infected people were included, 24% patients were current smokers 6.3% former smokers and 69.7% non-smokers. Smokers were male in majority with 93.2%. After their HIV infection status announcement, 64.9% have increased their tobacco consumption while 10.8% have decreased their consumption. Majority of patients have a good knowledge of the health risks of smoking. Of those who continue to smoke, 83.8% reported that they tried and fail to stop smoking at least one time. The main reason of their cessation was the effect on their health. And the main reason for the failure was the constant thinking of the disease. Conclusion: The announcement of the HIV positivity status must be accompanied by psychosocial support helping to overcome the emotion and stress and a smoking cessation program must be added to HIV screening program.
A study on Artificial Potential Fields

Having dealt with a very basic local sensing based path finding algorithm -tangent bug in the first homework, we will focus on again a very simple reactive path planning method, artificial potential fields(APF). APF is a reactive approach since the trajectories are not planned explicitly but obtained while executing actions by differentiating a function what is called potential function. A potential function is differentiable realvalued function U : R → R. The output of a potential function can be taken as the energy and it’s negative gradient as the net-force acting on the robot. In this report, two different potential functions are presented; attractive-repulsive potential function, and navigation function. These two functions are tested in a simulation environment with various configurations. Experiments are done on the robocup small-size league robot soccer platform that I have been started developing with the first homework. At the end, we see that both methods have some limitations and innate problems.
