Sun Zhigang's Death and Reform of Detention System

The Measures on Aid and Management for Urban Vagrants and Beggars, issued by the State Council in mid-July, took effect on August 1. It marks a further improvement of China’s mechanism to aid urban vagrants and beggars. The new regulation has been enacted to replace the two-decade-old Measures for the Internment and Deportation of Urban Vagrants and Beggars. This policy reform has stemmed from the astounding case of Sun Zhigang, a young man that was brutally beaten to death while in custody at the Guangzhou Detention Center.

Control of diffuse P-pollutants by multiple buffer/detention structures by Yuqiao Reservoir, North China

A case study on the transport process of agricultural diffuse P-pollutants was conducted in an experimental watershed locating in the north bank of Yuqiao Reservoir during 2001 and 2002. It was found that diversified artificial and natural buffer/detention landscape structures distributing along the ephemeral stream channel in this watershed played an important role of pollutants removal on downstream water quality, especially they have control effect on the diffuse P-pollutants transport process. Surface flow velocity was reduced sharply after passing through these structures. During continuous runoff events, the removal rate of TSS, TP, TDP, DRP by the whole system were 66.7%, 60.7%, 48.4%, and 43.3%, respectively. During discontinuous runoff events, removal rate of pollutants by the whole system was higher due to there was no or little surface water and pollutants exported from the watershed, of which removal rate of pollutants all exceeded 99%. The statistical analysis results of runoff events(n=8) indicated that dry pond was the steadiest structure for controlling diffuse P-pollutants export.

On-site stormwater detention for Australian development projects: Does it meet frequent flow management objectives?

On-site stormwater detention (OSD) is a conventional component of urban drainage systems, designed with the intention of mitigating the increase to peak discharge of stormwater runoff that inevitably results from urbanization. In Australia, singular temporal patterns for design storms have governed the inputs of hydrograph generation and in turn the design process of OSD for the last three decades. This paper raises the concern that many existing OSD systems designed using the singular temporal pattern for design storms may not be achieving their stated objectives when they are assessed against a variety of alternative temporal patterns. The performance of twenty real OSD systems was investigated using two methods:(1) ensembles of design temporal patterns prescribed in the latest version of Australian Rainfall and Runoff, and (2) real recorded rainfall data taken from pluviograph stations modeled with continuous simulation. It is shown conclusively that the use of singular temporal patterns is ineffective in providing assurance that an OSD will mitigate the increase to peak discharge for all possible storm events. Ensemble analysis is shown to provide improved results. However, it also falls short of providing any guarantee in the face of naturally occurring rainfall.

Incidence of Interpersonal Violence among Individuals with Drug Addiction Receiving Compulsory Treatment: A Survey at Two Drug Detention Centers in Hunan, China

Detention basins as best management practices for water quality control in an arid region

Flood control detention basins （DBs） can act as water quality control structures or best management practices （BMPs）. A key pollutant that DBs serve to settle out is particulate phosphorus, which adsorbs onto sediment. This study examines the sediment phosphorus concentration and its relationship with the particle size of sediment microcosms from pre- and post-rain event samples obtained from six DBs located in Clark County, Nevada. DBs were allotted a land use classification to determine if there was a correlation between the sediment phosphorus concentration and surrounding land use. The curve number method was used to calculate the runoff and subsequent phosphorus carried into the DB by the runoff. Our data show sediment phosphorus concentrations to he highest in soils from undeveloped areas. Runoff amount also plays a substantial role in determining the amount of phosphorus brought into the DB by sediment. This research has implications for improvement of water quality in arid regions.

Efficiency of locally available filter media on fluoride and phosphate removal for household water treatment system

Since conventional water treatment is not affordable in developing countries,looking for locally available and alternative treatment options is mandatory.Removal of fluoride and phosphate can be achieved by designing appropriate filtration media from different materials such as sand,calcined clay,pumice,scoria and bone char.This study was designed to determine the removal efficiency of these locally available filter media with respect to detention time and pH.The filtration apparatuses(tank) were filled separately with stone,gravel with grain size 0.6-4.75 mm and 40 cm deep,sand(ES = 0.15—0.35 mm and UC = 1.5-3),calcined clay,pumice,scoria and bone char with grain size 0.25-0.5 inch.Water samples were prepared using glass bottles with fluoride concentrations of 6 and 8 mg/1 and phosphate concentration of 4 mg/1.Laboratory analysis was carried out before and after filtration to determine the removal efficiency of each medium.It was found that the highest removal of fluoride was achieved by bone char(89.65%),followed by pumice(82.4%).However,bone char has rather increased the concentration of phosphate by 63.8%.Sand was the most efficient media to remove phosphate,managing to remove by 70%.Therefore,it is an attractive option to use these locally available,environmental friendly and appropriate technologies for efficient removal of both fluorine and phosphate at the household or community water treatment level.

The research on direct-drive wave energy conversion system and performance optimization

A direct-drive wave energy conversion system based on a three-phase permanent magnet tubular linear generator （PMTLG） and a heaving buoy is proposed to convert wave energy into electrical energy. Sufficient experimental methods are adopted to compare the computer simulations, the validity of which is verified by the experiment results from a wave tank laboratory. In the experiment, the motion curves of heaving buoy are with small fluctuations, mainly caused by the PMTLG＇s detent force. For the reduction of these small fluctuations and a maximum operational efficiency of the direct-drive wave energy conversion system, the PMTLG＇s detent force minimization technique and the heaving buoy optimization will be discussed. It is discovered that the operational efficiency of the direct-drive wave energy conversion system increases dramatically after optimization. The experiment and optimization results will provide useful reference for the future research on ocean wave energy conversion system.

Numerical analysis and evaluation of groundwater recession in a flood detention basin

This study analyzes the groundwater environment in the Yangzhuang flood detention basin in Henan Province,China.A numerical model of groundwater flow is established based on the hydrogeological conditions in the basin and changes of groundwater level in the flood detention basin under flood detention and recession conditions.The results show that during flood diversion and storage,the groundwater level in the basin rises,mainly in four flood detention zones,with a maximum rise of 1.0 m.After the floodwater recedes,the groundwater level slowly drops in the detention basin along with flood discharge,finally returning to its original level fifty days later.This study indicates that groundwater recession in the flood detention basin is a slow process,where the rise of groundwater level may cause environmental problems such as soil swamping.

Mental Disorders and Associated Factors among Adolescents in Juvenile Detention, Dar es Salaam, Tanzania

Introduction: The number of children and adolescents admitted in Dar es Salaam juvenile centers due to misbehavior and criminal offences has risen from 20 to 30 per month. Increasing aberrant behaviors in children have been linked to mental disorders. Assessment of presence mental health disorders as the main cause of these behaviors would be important to restore mental health of children and assist the system to impose a fair trial. Objective: This study aimed to determine the presence of mental disorders and associated factors among children and adolescents within Dar es Salaam juvenile systems and explore factors that may affect their mental health while in juvenile home. Methods: The mixed research method was used to estimate prevalence of mental disorders by a cross-sectional study and a qualitative method was applied to evaluate mental disorders according to DSM IV TR criteria. Results: The overall prevalence of mental dysfunction by mental status evaluation was 3%: 95% (CI;25.3 - 43.2;n =37 out of 108). The younger age group (13 - 15) years presented with a prevalence of 30%: 95% (CI;14.7 - 44.5) while the older adolescents (16 - 17 years) had a prevalence of 55%: 95% (CI;43.3 - 67.1). Attention deficit disorder was found in some children, some had history of drug and alcohol abuse, with few sexual disorders, depression and brief psychotic reaction and was found to be common among adolescent with unstable family situations such as death of parents, divorce of parents, and single parented children. Conclusion: Findings are suggestive that there is a presence of underlying mental disorders in some of the adolescents in the juvenile detention. Thus mental health screening for children in juvenile homes should be made mandatory in order to identify causes of aberrant behavior as well as provide treatment, prevent complications and maintain mental health of these children. Mental health screening for such children would also assist in conducting a fair trial for these emancipated children.

Diagnostic procedures and classification of antisocial behavior in Norwegian inmates in preventive detention

In official Norwegian government reports’ prison statistics, it is claimed that the prevalence of Dissocial Personality Disorder (DPD) or Antisocial Personality Disorder (APD) among inmates in preventive detention is approximately 50%. Furthermore, previous findings have described a practice in which forensic examiners use the DSM SCID axis II for APD to confirm an ICD 10 diagnosis of DPD. Clinical investigation supported by the use of SCID Axis II for quality assurance was performed on almost half the population of inmates (46.4%) in preventive detention at a high security prison. The inmates had all committed severe violent acts including murder. All the information obtained by applying the DSM IV-TR criteria was tested against the ICD-10 Research Criteria (ICD-10-RC) for Dissocial Personality Disorder (ICD-10, DPD). It was found that all inmates met the ICD-10-RC for (DPD) and the DSM-IV-TR definition for Adult Antisocial Behavior (AAB). On the other hand, none met the DSM-IV-TR criteria for (APD). The SCID Axis II failed to identify inmates with APD because the DSM-IV-TR C-criteria, referring to symptoms of childhood Conduct Disorder (CD), were not met. These findings raise important questions since the choice of diagnostic system may influence whether a person’s clinically described antisocial behaviour should be classified as a personality disorder or not. For the inmates, a diagnosis of APD or DPD may compromise their legal rights and affect decisions on prolongation of the preventive detention. Studies have shown that combining the DSM and the ICD diagnostic systems may have consequences for the reliability of the diagnosis.

Pre-trial Detention Houses and Protection of Detainees' Rights in China

Detainees’ rights in pre-trial detention houses are a means of assessing a country’s human rights protection. As a legal facility for carrying out criminal detention, a pre-trial detention house should remain neutral and safeguard detainees’ substantive and procedural rights. It should be an important base for the country to respect and protect human rights. At the macro level, protecting detainees’ rights comprises two aspects: 1) procedural rights, regarding which the principle of presumption of innocence should be applied; and 2) detainee treatment, regarding which the principle of socialization should be applied. At the current stage of China’s rights protection situation, China should improve detainees’ rights, such as the right to have an individual bed, the rights to health care and religious freedom, rules regarding the use of legirons, and transparency and independent monitoring mechanisms.

Human Rights for Detainees in Prisons and Detention Centers

China protects human rights of detainees in the entire process of the judicial system, from the making of law, to the administrationof justice, law enforcement and legal supervision. According to China＇s Constitution, detainees enjoy the following political rights： 1. All the rights that have not been deprived of just like ordinary citizens, including the fight of voting, the right to speech and publication; the fight to human dignity and non-humiliation, the right to non-infringement of personal safety, lawful property right and freedom of religious belief;

Numerical simulation of profile control by clay particles after polymer flooding

A three-dimensional,two-phase,five-component mathematical model has been developed to describe flow characteristics of clay particles and flocs in the profile control process,in which the clay particle suspension is injected into the formation to react with residual polymer.This model considers the reaction of clay particles with residual polymer,apparent viscosity of the mixture,retention of clay particles and flocs,as well as the decline in porosity and permeability caused by the retention of clay particles and flocs.A finite difference method is used to discretize the equation for each component in the model.The Runge-Kutta method is used to solve the polymer flow equation,and operator splitting algorithms are used to split the flow equation for clay particles into a hyperbolic equation for convection and a parabolic equation for diffusion,which effectively ensures excellent precision,high speed and good stability.The numerical simulation had been applied successfully in the 4-P1920 unit of the Lamadian Oilfield to forecast the blocking capacity of clay particle suspension and to optimize the injection parameters.

Application of a Coupled Land Surface-Hydrological Model to Flood Simulation in the Huaihe River Basin of China

A hydrological simulation in the Huaihe River Basin(HRB) was investigated using two different models: a coupled land surface hydrological model(CLHMS), and a large-scale hydrological model(LSX-HMS). The NCEP-NCAR reanalysis dataset and observed precipitation data were used as meteorological inputs. The simulation results from both models were compared in terms of flood processes forecasting during high flow periods in the summers of 2003 and 2007, and partial high flow periods in 2000. The comparison results showed that the simulated streamflow by CLHMS model agreed well with the observations with Nash-Sutcliffe coefficients larger than 0.76, in both periods of 2000 at Lutaizi and Bengbu stations in the HRB, while the skill of the LSX-HMS model was relatively poor. The simulation results for the high flow periods in 2003 and 2007 suggested that the CLHMS model can simulate both the peak time and intensity of the hydrological processes, while the LSX-HMS model provides a delayed flood peak. These results demonstrated the importance of considering the coupling between the land surface and hydrological module in achieving better predictions for hydrological processes, and CLHMS was proven to be a promising model for future applications in flood simulation and forecasting.

Optimal design of FRMSM to decrease detent force

An optimal configuration of the flux-reversal linear synchronous motor (FRLSM) with the optimal number of attachment permanent magnets (PMs) was presented. The optimal model of 2 000 N was designed to reduce the detent force by redesigning the air-gap structure and skewing. The design parameters,mover PMs and stator core,were selected for optimal design by DOE. The thrust and the detent force of the designed optimal models were compared by finite element analysis (FEA). As a result,the thrust of the optimal model is slightly decreased by 1.97% compared with the basic model,and the detent force of the optimal model is greatly decreased by 88.47% compared with the basic model.

Design strategy for detent force reduction of permanent magnet linear synchronous motor

The detent force of a permanent magnet linear synchronous motor （PMLSM） is analyzed and the corresponding optimization methods are presented to reduce it. The detent force, which is divided into two components, i.e. resulting from the end effect and resulting from the slotting effect, can be analyzed respectively by the finite element method （FEM）. To reduce the detent force arising from the end effect, several optimal design techniques are utilized, namely, adopting the suitable length and end shape of the primary armature. The detent force resulting from the slotting effect is reduced by means of skewing and adjusting the width of the magnets mounted on the secondary armature, and adopting the fractional slots of the primary armature. The validity of the analytical detent force predictions and the effectiveness of the detent force reduction techniques are verified by the experimental measurements.

Experience of Planning the Local Climate Change Adaptation Plan in Taoyuan

Based on the experience of emergency operation on earthquake and flooding in local and foreign countries, the secondary disasters of fire, damage of critical infrastructure usually harmed lives or disturbed living condition. In order to safeguard people＇s lives and property safety, Taoyuan City Government, except for elementary public facilities, added standardized disaster prevention parks and detention ponds in the zone-expropriation project at Chunglu area. The zone-expropriation project at Chunglu, Taoyuan is designed for 487,600 residents in 2021. The area of public facilities of park, school, road and green land is 50.7 ha, 41.88% of total development area of 122.06 ha, in which, the capacity of disaster prevention parks at Chunglu area is designed for 3,164 refugee in 7.54 ha. An underground storage construction, withstand 7-magnitude earthquake, could supply the amount of water consumption of 3 L daily per person, lasting at least four weeks. The capacity of two detention ponds is 87,800 m3. During normal times, the disaster prevention park and detention ponds can be used as a recreational space for residents. When a disaster occurs, shelters are set up in the parks to accommodate residents to protect lives and property. And, detention ponds could adjust outflow discharge into neighborhood drainage system to mitigate disaster happening. Because the construction of standardized disaster prevention park with climate change needs much more land area, the acquisition of private land area is very difficult either general acquisition or zone expropriation in urban area. During each stage of zone expropriation, the support of landlord and Mayor Wu is very important. By means of public participation, information meeting was held hundreds times and revised content according to landlord＇s positive opinion. Moreover, the design idea and content was discussed with consultant-company mutually from time to time. Fortunately, this project is finished successfully and got award from Public Construction Council of Taiwan in 2014.

Northeast Asia amid Korean Detente

Northeast Asia has all along been a place of great importance for major powers in the Far East. Because of its special geographical position, these powers have competed against each other for spheres of influence in the region since the very beginning of the 20th century. Therefore, the present detente on the Korean peninsula will inevitably affect some big powers’ interests and exert a far-reaching influence on Asia-Pacific and world security situation.

Epidemiological and Psychosocial Profile of Juvenile Delinquency: Case Study of Delinquent Children and Adolescents under Court Order in Benin (2015)

Background: Given the scale of juvenile delinquency in Benin, families, judicial bodies and the society seemed overwhelmed. The objective was to study the epidemiological and psychosocial profile of delinquent children and adolescents under court order (DCAUCO) in Benin civil prisons in 2015. Methods of study: It was a descriptive and cross-sectional study which involved 117 children aged 11 to 18 years, recruited from 6th May to 10th September 2015 in nine Civil Prisons and a Child and Adolescent Care Center in Benin. Data were collected through face-to-face interview between the interviewer and the interviewee in addition to ASSIST-WHO, Family Assessment Device and ParentalAcceptance and Rejection Scale. Results: The average age was 16.1 ± 1.1 years, ranging from 11 to 18 years. Sex ratio M/F was 22.4. School dropout rate was 76.9%. Orphans represented 53.9%. The proportion of juvenile offenders coming from broken families was 30.8%. Theft (46.2%) and rape (19.7%) were the main offenses committed. 99.1% had no criminal records and the judge requested for all of them a detention warrant. Psychoactive substance consumption records (46.2%) were found, including: alcohol (46.2%), tobacco (23.9%), and cannabis (10.3%). They felt maternal and paternal absence respectively in 48.7% and 44.4% cases and pleaded guilty in 71.8%. Pleading guilty was a resilience factor on which the counseling would have to rely for their rehabilitation and social reintegration.
