“I Used to Be an Offender—Now I'm a Defender”: Positive Psychology Approaches in the Facilitation of Posttraumatic Growth in Offenders

This study identifies positive psychology concepts and interventions in an offender rehabilitation program in South Africa. The concepts and interventions are cross-referenced to the literature and are found to conform to the principles of the good livesdesistance model (Laws & Ward, 2011). The study uses inductive thematic analysis (Braun & Clarke, 2006) to assess the impact of the program on fourteen ex-offenders and proposes an answer to the question, “What does desistance look like? ” (Maruna, 2001). In this study it appears that desistance may be related to posttraumatic growth (Tedeschi, 2011), and this raises the possibility that rehabilitation programs that encourage posttraumatic growth could be effective in facilitating desistance. Further research is recommended into programs that use positive psychology interventions and posttraumatic growth methods due to the fact that existing valid programs may be at risk of being rejected by authorities who use the “what works” and risks need responsivity model (Bonta & Andrews, 2007) as a benchmark.
How the Reformulation of OxyContin Ignited the Heroin Epidemic

Abstract We attribute the recent quadrupling of heroin death rates to the August 2010 reformulation of an oft-abused prescription opioid, OxyContin. The new abuse-deterrent formulation led many consumers to substitute an inexpensive alternative, heroin. Using structural break techniques and variation in substitution risk, we find that opioid consumption stops rising in August 2010, heroin deaths begin climbing the following month, and growth in heroin deaths was greater in areas with greater prereformulation access to heroin and opioids. The reformulation did not generate a reduction in combined heroin and opioid mortality: each prevented opioid death was replaced with a heroin death.
Primary Host VMM VM Secondary HostClient ’ s View Time Network Packet ( k ) Epoch ( i ) Pause Epoch

Fault tolerance has become increasingly critical for virtualized systems as growing amount of mission-critical applications are now deployed on virtual machines rather than directly on physical machines. However, prior hardware-based fault-tolerant systems require extensive modification to existing hardware, which makes them infeasible for industry practitioners. Although software-based techniques realize fault tolerance without any hardware modification, they suffer from significant latency overhead that is often orders of magnitude higher than acceptable. To realize practical low-latency fault tolerance in the virtualized environment, we first identify two bottlenecks in prior approaches, namely the overhead for tracking dirty pages in software and the long sequential dependency in checkpointing system states. To address these bottlenecks, we design a novel mechanism to asynchronously prefetch the dirty pages without disrupting the primary VM execution to shorten the sequential dependency. We then develop Phantasy, a system that leverages page-modification logging (PML) technology available on commodity processors to reduce the dirty page tracking overhead and asynchronously prefetches dirty pages through direct remote memory access via RDMA. Evaluated on 25 real-world applications, we demonstrate Phantasy can significantly reduce the performance overhead by 38% on average, and further reduce the latency by 85% compared to a state-of-the-art virtualization-based fault-tolerant system.
A Novel Approach for Representing Ice Microphysics in Models: Description and Tests Using a Kinematic Framework

Abstract This paper documents the development of a novel approach for representing ice microphysics in numerical models. In this approach, the ice particle mass–dimension and projected-area–dimension relationships vary as a function of particle size and rimed mass fraction. All ice microphysical processes and parameters are calculated in a self-consistent manner in terms of these mass–dimension and area–dimension relationships. The rimed mass fraction is predicted locally by separately predicting the ice mixing ratios acquired through water vapor deposition and through riming. The third predicted variable is the number concentration of ice particles. This approach allows representing in a natural way the gradual transition from small to large ice particles due to growth by water vapor deposition and aggregation and from unrimed crystals to graupel due to riming. In traditional approaches, these processes are treated by separating ice particles into predefined categories (such as cloud ice, snow, and graup.
Can Foreign Health Assistance Reduce the Medical Brain Drain?

In this article, we analyse the impact of foreign health aid on the emigration rates of physicians. The analysis is based on a dataset of physician emigration rates from 50 source countries between 1998 and 2004. First, we investigate the direct impact of health assistance using the generalised method of moments estimation, and we highlight the significant negative effect of foreign health assistance on the medical brain drain. Second, we show that this effect results more from technical assistance than from financial assistance. Finally, the robustness of our analysis is verified to confirm the validity of the results.
A review of global ocean temperature observations: Implications for ocean heat content estimates and climate change

The evolution of ocean temperature measurement systems is presented with a focus on the development and accuracy of two critical devices in use today (expendable bathythermographs and conductivity‐temperature‐depth instruments used on Argo floats). A detailed discussion of the accuracy of these devices and a projection of the future of ocean temperature measurements are provided. The accuracy of ocean temperature measurements is discussed in detail in the context of ocean heat content, Earth's energy imbalance, and thermosteric sea level rise. Up‐to‐date estimates are provided for these three important quantities. The total energy imbalance at the top of atmosphere is best assessed by taking an inventory of changes in energy storage. The main storage is in the ocean, the latest values of which are presented. Furthermore, despite differences in measurement methods and analysis techniques, multiple studies show that there has been a multidecadal increase in the heat content of both the upper and deep ocean regions, which reflects the impact of anthropogenic warming. With respect to sea level rise, mutually reinforcing information from tide gauges and radar altimetry shows that presently, sea level is rising at approximately 3 mm yr−1 with contributions from both thermal expansion and mass accumulation from ice melt. The latest data for thermal expansion sea level rise are included here and analyzed.
TWO FACTOR AUTHENTICATIONS FOR SECURED LOGIN IN SUPPORT OF EFFECTIVE INFORMATION PRESERVATION AND NETWORK SECURITY

In the present digital day with remarkable development in Computer sector, Single factor authentication, e.g. passwords, is no more examined as secure in the World Wide Web. It has never been less difficult in Securing the system and remote access. Simple, obvious and easy-to-guess passwords, such as names and age, are effortlessly found via computerized secret key gathering programs. The security and privacy threats through malware are always constantly growing both in quantity as well as quality. Expanded access to information increases weakness to hacking, cracking of passwords and online frauds. In this association the conventional login/password authentication is taken into account inadequately secure for several security-critical applications such as login to Mailing Accounts, Social Networks, Gadgets, Financial accounts, official secured networks, commercial websites online etc. Obliging more than one independent factor increases the difficulty of providing false credentials. Two-factor authentication proposal guarantee a higher protection level by extending the single authentication factor. This paper focuses on the implementation of two-factor authentication methods by using both users friendly traditional Alphanumeric Password and graphical Password as gateway for authentication. An attempt has been made by using two factor Authentication, and in this paper we describe the two factor Authentication system design and design implementation. Thus affording an additional password adds an extra layer of security.
Photocatalytic Activity, Surface Morphology, and Mechanical Properties of Atmospheric Plasma-treated HTPET Fiber with SnO2 Coating

SnO2 hydrosol made in the lab was deposited on HTPET fibers by dip-coating method. In order to improve the deposition of the coating layer and water adsorption properties of the fiber, atmospheric plasma treatment was used as pre-treatment to enhance the interaction at the interface. Photocatalytic properties of the samples coated with SnO2 under different plasma treatments were analyzed through the degradation of methylene blue under UV-light. The morphologies and surface modulus of SnO2 coated fibers were characterized by Scanning Electronic Microscope (SEM) and Atomic Force Microscopy (AFM), respectively. The effects of plasma treatment on water adsorption behavior of the fibers were examined by contact angle measurement instrument. Tensile tests were carried out to measure and assess the mechanical properties of HTPET fiber before and after plasma treatment and photocatalysis was done. The study revealed that the photocatalytic activity of SnO2 coated HTPET fibers were enhanced due to the wettability of HTPET surfaces improved by plasma treatment and varying degrees of surface etching which benefited SnO2 adhesion on HTPET fibers. Meanwhile, the modulus of monofilament surface increased under plasma treatment but decreased after phtotcatalysis. Mechanical properties of the fibers exhibited an opposite trend. It was found that the best photocatalytic activity of HTPET fibre was obtained under 100 w power plasma treatment.
Pulsed Laser Deposition of ITO: From Films to Nanostructures

Indium-tin oxide (ITO) films have been deposited by pulsed laser deposition (PLD) to achieve low resistivity and high transmittance in visible region. Important parameters governing the growth of ITO films, which include laser wavelength, substrate tempera - ture, and the background gas pressure, are discussed. By utilizing the energetic plasma in laser ablation of an ITO target, relatively low substrate temperature growth has been demonstrated. Room temperature deposition enables ITO films to be deposited on the polymer substrate. In addition, deposition in different background gases promotes the catalyst-free growth of nanostructured ITO films. In particular, deposition in Ar or He at optimized pressures enables the growth of highly crystalline ITO nanostructures, which include nanorods and nanowires due to the self-catalyzed growth from the plasma plume. The conditions which allow the pulsed laser deposition of ITO thin films and the growth of nanostructured ITO are reviewed and discussed.
The Russian growth path and TFP changes in light of estimation of the production function using quarterly data

This article presents estimations of a Cobb–Douglas production function with a steady change in total factor productivity (TFP) for the Russian economy using quarterly data for the favourable period 1998Q3–2008Q2 and the period 1995Q1–2010Q2 as well. Compiling our baseline data on capital and labour adjusted for utilisation, we explicitly present estimations of the coefficients (the capital distribution ratio and TFP) of the production function, which show that TFP is the major growth source, followed by the capital contribution. We also show results of the measurement of Russia's GDP gaps as the differences between potential and actual GDP based on the production function and the Hodrick–Prescott filter.

Simulation of the Intraseasonal Variance of the South American Summer Monsoon

Abstract This study reveals the inadequacy of the Center for Ocean–Land–Atmosphere Studies (COLA) atmospheric general circulation model (AGCM) and the National Centers for Environmental Prediction–National Center for Atmospheric Research (NCEP–NCAR) reanalysis to resolve the variance of the intraseasonal anomalies of outgoing longwave radiation (OLR) over the South American summer monsoon (SASM) domain and the equatorial eastern Pacific Ocean (EEPO) owing to their coarse horizontal resolution. However, when the NCEP–NCAR reanalysis is downscaled by roughly a factor of 2.5 using the Regional Spectral Model (RSM; control-A experiment), the simulation of the seasonal mean variance of intraseasonal anomalies of OLR improves significantly. But downscaling the results of the COLA AGCM (control-B experiment) by roughly a factor of 4 led to no further improvement. Using the novel technique of anomaly nesting, which replaces the climatology of the COLA AGCM of the nested variables at the lateral boundaries of the .
In situ trap properties in CCDs: the donor level of the silicon divacancy

The silicon divacancy is one of the main defects of concern in radiation damage studies of Charge-Coupled Devices (CCDs) and, being immobile at room temperature, the defect is accessible to a variety of characterisation techniques. As such, there is a large amount of (often conflicting) information in the literature regarding this defect. Here we study the donor level of the divacancy, one of three energy levels which lie between the silicon valence and conduction bands. The donor level of the divacancy acts as a trap for holes in silicon and therefore can be studied through the use of a p-channel CCD. The method of trap-pumping, linked closely to the process of pocket-pumping, has been demonstrated in the literature over the last two years to allow for in-situ analysis of defects in the silicon of CCDs. However, most work so far has been a demonstartion of the techinique. We begin here to use the technique for detailed studies of a specific defect centre in silicon, the donor level of the divacancy. The trap density post-irradiation can be found, and each instance of the trap identified independently of all others. Through the study of the trap response at different clocking frequencies one can measure directly the defect emission time constant, and through tracking this at different temperatures, it is possible to use Shockley-Read-Hall theory to calculate the trap energy level and cross-section. A large population of traps, all with parameters consistent with the donor level of the divacancy, has been studied, leading to a measure of the distribution of properties. The emission time constant, energy level and cross-section are found to have relatively large spreads, significantly beyond the small uncertainty in the measurement technique. This spread has major implications on the correction of charge transfer inefficiency effects in space applications in which high precision is required.
Evaluation of Antibacterial, Antifunfgal and Cytotoxic Potentials of Crude Metabolite of ANAM-39, a Marine Bacterium Isolated from Sundarbans, Bangladesh

The present study was undertaken to screen the antimicrobial, antifungal and cytotoxic potentials of crude metabolite of a marine bacterium isolated from a soil sample collected from Sundarbans, Bangladesh. Primary and secondary screenings for antimicrobial activity were conducted by cross streak and agar well diffusion method, respectively. The antifungal potency of the crude extract was also tested by agar well-diffusion method. The brine shrimp lethality test was conducted to determine the cytotoxic nature of crude metabolites, which showed that the degree of lethality of metabolite was directly proportional to the concentration (LC50 30.19 μg/ml). Further studies are needed to isolate and characterize the active principles present in the crude metabolite and determine their biological activity. The results of this investigation suggested that the soils of Sundarbans are rich sources of microorganisms with potent biological activities and systematic screening programs need to be conducted to explore the presence of pharmacologically active marine bacterial metabolites.

EFFECTS OF POLLEN TYPHAE TOTAL FLAVONE ON β-ARRESTIN-2/SRC/ AKT SIGNALING IN ADIPOSE TISSUES OF TYPE 2 DIABETIC RATS

Background: Pollen Typhae total flavone (PTF), the extract from Pollen Typhae, a Chinese herbal medicine, has been reported to improve insulin resistance in type 2 diabetic rats, but the potential mechanisms keep unclear. Materials and Methods: Type 2 diabetic model rats were induced by high-fat diet and low-dose streptozotocin, and then were administered PTF by intragastrical gavage. After treatment for 4 weeks, insulin receptor-β level in adipose tissues was determined by ELISA, and the protein expression was analyzed by western blotting. Results: Administration of PTF increased insulin receptor-β level and enhanced β-arrestin-2 protein expression in adipose tissues of type 2 diabetic rats. Although having no effect on the protein expression of Src or Akt, PTF promoted phosphorylation of Src at Tyr416 and Akt at Ser473. Conclusion: The results indicate that PTF has beneficial effects on the β-arrestin-2/Src/Akt signaling in adipose tissues of type 2 diabetic rats, implying the underlying mechanisms of PTF in ameliorating insulin resistance.
Paper : Earthquake Early Warning Technology Progress in Taiwan

The dense real-time earthquake monitoring network established in Taiwan is a strong base for the development of the earthquake early warning (EEW) system. In remarkable progress over the last decades, realtime earthquake warning messages are sent within 20 sec after an event using the regional EEW system with a virtual subnetwork approach. An onsite EEW approach using the first 3 sec of P waves has been developed and under online experimentation. Integrating regional and onsite systems may enable EEW messages to be issued within 10 sec after an event occurred in the near future. This study mainly discusses the methodology for determining the magnitude and ground motion of an event.
Interaction of Technological Marketing and Porter’s Five Competitive Forces on SME Competitiveness in South Africa

Principally, this study sought to investigate the influence of technological marketing on Porter’s five competitive forces model of SMEs in the Buffalo City Metropolitan Municipality. The research problem, herein, arises from a theoretical and pragmatic gap around the lack of consensus between the positive and negative impacts of technological marketing developments on industry structure. The study employed a quantitative method in data collection from a sample of 211 SME owners/managers in the retail and manufacturing sectors of Buffalo City Metropolitan Municipality, South Africa. The sample data was analysed using SEM. The principal finding of this study reveals that technological marketing has no significant impact on Porter’s five competitive forces. The findings have important implications for enhancing the adoption of new technologies in marketing SME products/services. DOI: 10.5901/mjss.2014. v5n4p254
