Self-harm behavior displays a higher prevalence in prison, 11 to 14 times greater than in the general population. Our study extended the current research in self-harm by examining dynamic factors of self-harm in adolescents over their sentence in the Romanian juvenile prison system. <strong>Method: </strong>The present research examined longitudinal predictors of self-harm behaviors in 439 adolescent inmates (Mage = 16.21;5.2% female, 94.8% male), enrolled in prison during 2011-2012, following them for two years. A series of time-to-event analyses were applied to start from the time of the subject’s internment in the juvenile prison system. <strong>Results:</strong> Findings from the multivariate survival analyses show that adherence to self-harm conduct in prison was consistently influenced by family factors and prison contexts;although low ability to cope with frustration, sensitivity and emotion dysregulation also mattered. Keeping the other covariates invariant, serving a prison sentence in a closed regime reduces the probability of remaining free of self-harm events, increasing the monthly hazard of self-harm by a factor of 5.26 on average (HR = 5.26, 95% CI = 2.37 - 11.64) compared to the open regime. <strong>Conclusion:</strong> A greater focus on longitudinal studies may help improve the screening process and also follow the progress of each juvenile to warrant the efficacy of preventive programs in self-harm, according to their emerging needs. 展开更多

Background: Research suggests that a small number of persistent violent offenders are responsible for a majority of prison violence and tend to behave violently to a disproportionate amount. However, literature on patterns of violence in juvenile prisoners is limited. Method: In order to explore how subjects engage in violence while incarcerated in the juvenile prison system, the authors will examine both proximal and distal predictors of violent behavior among juveniles in custody. This study adds to the current empirical research by longitudinally examining dynamic risk factors of recurrent violent behavior across a population of juvenile prisoners (Mage = 16.21;94.8% male) in custody in the Romanian juvenile justice system, starting from their entry date until the end of the follow-up period (Me = 2 years). Results: Results from a series of repeated aggressive events survival analyses show evidence of a long-term deleterious association between pre-incarceration risk factors and poor developmental trajectory associated with violence. Adherence to destructive conduct in prison was consistently influenced by low ability to cope with the prison environment, although education level and family factors also mattered. Implications for prison professionals and forensic practitioners are presented. Conclusion: Recurring aggressive behavior is frequent for individuals who experience complex adverse experiences during childhood, suggesting that screening youths upon their admission into juvenile justice settings should include an assessment of their basic self-regulation needs. A greater focus on longitudinal studies may help improve the screening process and also follow the progress of each juvenile to warrant the efficacy of preventive programs in self-harm, according to their emerging needs. 展开更多

During the Tang Dynasty,incarcerated prisoners enjoyed various rights during their detention,including access to clothing,food,medical care,hygiene,rest,and burial arrangements.Under specific conditions,prisoners were even granted leave for family events such as funerals or weddings.The Rules for Prison Officials(Yuguanling)detailed the rights and safeguards for prisoners and set clear guidelines on the use of restraints during detention.Additionally,the Statutes on Deciding Cases(Duanyu Lü)outlined explicit penalties for judicial officials who failed to ensure prisoner rights or committed related violations.Interrogation processes adhered to strict procedural and substantive requirements,including direct questioning by judges,the avoidance of cases involving personal connections or conflicts of interest,evidence-based cross-examinations,careful investigation of circumstances,and consistent rulings across similar cases.The Tang legal code imposed comprehensive,detailed,and stringent limits on the application of coercive interrogations,specifying restrictions on tools,methods,subjects,and extent.Any breaches of these restrictions were met with severe punishments.While the concept of“human rights”did not appear in Tang legal and administrative texts,these laws and regulations embody abundant principles of people-centered governance,benevolence,and human rights concepts.Systematic examination of these ideas,values,and principles—when integrated with the Marxist perspective on human rights—can enrich China’s contemporary human rights practice,contribute to articulating China’s unique narrative on human rights,and play a role in constructing a distinctly Chinese discourse on human rights.Such efforts could provide Chinese wisdom and proposals for the advancement of human rights globally. 展开更多

BACKGROUND Prisons can be a reservoir for infectious diseases,including severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),due to the very intimate nature of the living spaces and the large number of people forced to share them.AIM To investigate the SARS-CoV-2 epidemiology in prisons,this study evaluated the infection incidence rate in prisoners who underwent nasopharyngeal swabs.METHODS This is an observational cohort study.Data collection included information on prisoners who underwent nasopharyngeal swab testing for SARS-CoV-2 and the results.Nasopharyngeal swab tests for SARS-CoV-2 were performed between 15 February 2021 and 31 May 2021 for prisoners with symptoms and all new arrivals to the facility.Another section included information on the diagnosis of the disease according to the International Classification of Diseases,Ninth Revision,and Clinical Modification.RESULTS Up until the 31 May 2021,79.2%of the prisoner cohort(n=1744)agreed to a nasopharyngeal swab test(n=1381).Of these,1288 were negative(93.3%)and 85 were positive(6.2%).A significant association[relative risk(RR)]was found only for the risk of SARS-CoV-2 infection among foreigners compared to Italians[RR=2.4,95%confidence interval(CI):1.2-4.8].A positive association with SARS-CoV-2 infection was also found for inmates with at least one nervous system disorder(RR=4,95%CI:1.8-9.1).The SARS-CoV-2 incidence rate among prisoners is significantly lower than in the general population in Tuscany(standardized incidence ratio 0.7,95%CI:0.6-0.9).CONCLUSION In the prisoner cohort,screening and rapid access to health care for the immigrant population were critical to limiting virus transmission and subsequent morbidity and mortality in this vulnerable population. 展开更多

Introduction: Hepatitis B virus (HBV) infection is a major public health problem in Cameroon. Garoua city is the headquarters of the North Region of Cameroon, where the HBV prevalence is among the highest of the country. The aim of this study was to determine the prevalence of HBsAg carriage and associated factors among persons incarcerated in the Garoua Central Prison. Methods: It was a cross-sectional study conducted from July 1 to July 31, 2023 at the Garoua Central prison. We included all prisoners willing to participate in the study and who gave their verbal consent. We collected data using a pre-established data entry form and we used rapid test for blood screening for HBV surface antigen (HBs Ag) with ELISA confirmation. Data were analyzed using the R<sup>®</sup> software for Windows. After the univariate analysis, we selected associated variables to HBV infection with p-value p-value was set at 5%. Results: We included 1389 prisoners out of which 97.6% were male. The median age (IQR) of the study population was 28 (23 - 35) years. The median (IQR) duration of incarceration was 12 (6 - 26) months and the mean (±sd) number of incarcerations was 1.24 (±0.6). HBV prevalence was estimated at 14.8% (95% CI: 13.0 - 16.7). Upon uni- and multivariate analysis, no risk factor was significantly associated with viral hepatitis B infection in our study population. Conclusion: The prevalence of Hepatitis B was high in the Garoua Central Prison, but there were no additional risk factors for HBV infection. There is a need to include the Garoua Central Prison and by the way other prisons in the country in the chronic viral hepatitis care program. 展开更多

The“prisoner’s dilemma”illustrates that everyone is rationally thinking about maximizing their own interests and taking their own best strategies,but the end result is counterproductive.In Prisoner’s Dilemma Richard Powers describes multiformareas of dilemma;to lose balance;to make choices;and ask each other:what to do next?It is a master trope for relaying the permanent impasse or dilemma of cooperation versus defection.In most cases,the prisoner's dilemma is more about the number of defeats in the game,and even a major loss of society.Individual rationality is likely to be a collective disregard,and if everyone is acting on the principle of self-interest,it is often the result that everyone is lost.Powers expresses his philosophical insight:Until a cooperative instead of antagonistic solution is collectively agreed upon,we still remain imprisoned in an interminable and oppressive struggle and conflict decided by self-interest and rational control,which is also a moral response to historical consciousness of postmodernism. 展开更多

The intentional ingestion of foreign objects(IIFO) is described more commonly in prison populations than in the general population, with an estimated annual incidence of 1 in 1900 inmates in our state correctional facilities. Incidents often involve ingestion of small metal objects(e.g., paperclips, razor blades) or other commonly available items like pens or eating utensils. Despite ingestion of relatively sharp objects, most episodes can be clinically managed with either observation or endoscopy. Surgery should be reserved for those with signs or symptoms of gastrointestinal perforation or obstruction. For those with a history of IIFO, efforts should focus on prevention of recurrenceas subsequent episodes are associated with higher morbidity, significant healthcare and security costs. The pattern of IIFO is often repetitive, with escalation both in frequency of ingestions and in number of items ingested. Little is known about successful prevention strategies, but efforts to monitor patients and provide psychiatric care are potential best-practice strategies. This article aims to provide state-of-the art review on the topic, followed by a set of basic recommendations. 展开更多

The iterated prisoner's dilemma(IPD) is an ideal model for analyzing interactions between agents in complex networks. It has attracted wide interest in the development of novel strategies since the success of tit-for-tat in Axelrod's tournament. This paper studies a new adaptive strategy of IPD in different complex networks, where agents can learn and adapt their strategies through reinforcement learning method. A temporal difference learning method is applied for designing the adaptive strategy to optimize the decision making process of the agents. Previous studies indicated that mutual cooperation is hard to emerge in the IPD. Therefore, three examples which based on square lattice network and scale-free network are provided to show two features of the adaptive strategy. First, the mutual cooperation can be achieved by the group with adaptive agents under scale-free network, and once evolution has converged mutual cooperation, it is unlikely to shift. Secondly, the adaptive strategy can earn a better payoff compared with other strategies in the square network. The analytical properties are discussed for verifying evolutionary stability of the adaptive strategy. 展开更多

AIM:Recent studies in Iran has shown that prevalence of hepatitis C virus (HCV) infection among Iranian prisoners is high, in spite of low HCV seroprevalence in general population. METHODS: This study was carried out in the central prison of Hamedan - Iran, in year 2002. Inmates were interviewed using a standard questionnaire including demographic, imprisonment history and HCV-related risk behaviors items. Thereafter, the sera drawn from the participants were tested for anti-HIV and anti-HCV antibodies. RESULTS: A total number of 427 drug abuser inmates participated in our study. Three hundred and ninety-seven (93%) were men and 30 (7%) were women. Total number of IV drug abusers (IDA) and non-IV drug abusers (NIDA) was 149 (34.9%) and 278 (65.1%), respectively. The overall rate of antibody positivity among inmates was 0.9% for HIV and 30% for HCV. Of all IDAs, 31.5% and of NIDAs, 29.1% had serological evidence of HCV infection. CONCLUSION: The seroprevalence of HCV infection among drug abuser prisoners in comparison with the general population in Iran, is very high (30% vs in italics 0.2%). Our results indicate the importance of policies to prevent transmission of HCV infection during and following incarceration. 展开更多

We analyzed prevalently the articles appearing on Pub Med in the last ten years. HCV infection is frequent in prisoners, prevalences ranging from 3.1% to 38% according to the HCV endemicity in the geographical location of the prison and in the countries of origin of the foreign prisoners and to the prevalence of intravenous drug use, which is the most important risk factor for HCV infection, followed by an older age of prisoners and previous prison terms. HCV replication in anti-HCVpositive cases varies from 45% to 90% in different studies, and the most common HCV genotypes are generally 1 and 3. The response to antiviral treatment is similar in prisoners to that of the general population. Unfortunately, treatment is administered less frequently to prisoners because of the difficulties in management and follow-up. The new directly acting antivirals offer a good therapy option for inmates because of their good efficacy, short duration of treatment and low incidence of side effects. The efforts of the prison authorities and medical staff should be focused on reducing the spread of HCV infection in prisons by extending the possibility of follow-up and treatment to more prisoners with chronic hepatitis C. 展开更多

This paper studies the continuous prisoner's dilemma games (CPDG) on Barabasi-Albert (BA) networks.In the model,each agent on a vertex of the networks makes an investment and interacts with all of his neighboring agents.Making an investment is costly,but which benefits its neighboring agents,where benefit and cost depend on the level of investment made.The payoff of each agent is given by the sum of payoffs it receives in its interactions with all its neighbors.Not only payoff,individual's guilty emotion in the games has also been considered.The negative guilty emotion produced in comparing with its neighbors can reduce the utility of individuals directly.We assume that the reduction amount depends on the individual's degree and a baseline level parameter.The group's cooperative level is characterized by the average investment of the population.Each player makes his investment in the next step based on a convex combination of the investment of his best neighbors in the last step,his best history strategies in the latest steps which number is controlled by a memory length parameter,and a uniformly distributed random number.Simulation results show that this degree-dependent guilt mechanism can promote the evolution of cooperation dramatically comparing with degree-independent guilt or no guilt cases.Imitation,memory,uncertainty coefficients and network structure also play determinant roles in the cooperation level of the population.All our results may shed some new light on studying the evolution of cooperation based on network reciprocity mechanisms. 展开更多

Aim of this research is to explore the relation of hunting with aggressiveness. For this purpose, two samples of prison inmates (who were students of the prison secondary school) were collected (class A = 23, class B = 12). The network indicators for superficial, idiosyncratic and strategic behavior (particularly, aggressiveness), applied in Bekiari and Hasanagas (2016), which were based on the primary network variables (outdegree, indegree, Katz status, pagerank, authority) were used. Non-network variables were also used for the criminal profile of the inmates. The data were sampled with questionnaire. Spearman test was conducted for detecting correlation between aggressiveness and hunting and Principal Component Analysis was used for formulating a typology. The following results were produced: The criminal profile seems hardly to be related with hunting experience or attitude. The relation of hunting experience and attitude with the superficial, idiosyncratic and strategic aggressiveness was examined. These three occasions of aggressiveness are expected to describe the incidental reaction, impulsive and adaptive reaction, respectively. The hunting is quite irrelevant to the incidental reaction. The impulsiveness seems to be more strongly correlated with hunting. In case of adaptiveness, there are many similarities with impulsiveness. The typology which is based on the existence (or not) of hunting experience seems to be more insightful, as it reveals a gradual involvement of aggressiveness dimensions, from incidentality to impulsiveness and further to adaptiveness. The following behavioral patterns of gradually enhanced aggressiveness appear: incidentally just provoking, impulsively being aggressive but without harming, and adaptively being aggressive and harming. 展开更多
