Child Abuse and Neglect: An Overview

Child abuse and neglect are serious global problems and can be in the form of physical, sexual, emotional or just neglect in providing for the child's needs. These factors can leave the child with serious, long-lasting psychological damage. Child maltreatment is a complex life experience occurs when a parent or caregiver does an intentional or potential damage to a child, including acts of commission and omission. Child abuse is not an uncommon event, but it is not always recognized. Identifying the real number of maltreated children is a challenge because of the large variability in reported prevalence data across studies. It is associated with important economic and social costs (such as physical and mental health, productivity losses, child welfare, criminal justice and special education costs) due to its high prevalence and its long-term and short-term consequences.

Understanding and application of crime of sabotaging production and operation in internet era

PurposeThe purpose of this study is to investigate the understanding and application of crime of sabotaging production and operation in internet era, and, at the same time, discuss the basic position for criminal law interpretation in cyberspace.Design/methodology/approachDoctrinal analysis and case study.FindingsAlong with the advent of the internet era, how to apply the traditional crime of sabotaging production and operation in virtual space has attracted people’s attention. The controversy caused by the conviction of malicious application of fake transactions is a typical example. The legal interest protected here includes not only the property value of the means of production itself, but also the expectation interest that can be obtained by normal production and operation activities. There is no reliable basis to believe that overlap of articles between special provision and general laws occurs in crime of sabotaging production and operation and crime of intentional damage of property. The production and operation activities carried out online can also be covered by crime of sabotaging production and operation, without doubt. Ejusdem Generis Rule should be fully respected, but crime of sabotaging production and operation has a dual structure of means behavior and purpose behavior, where the purpose behavior, sabotaging production and operation, is the key to the conviction. However, it is not necessarily premised on physical damage and violent characteristics. The understanding and application of traditional crimes should keep pace with the times in the internet era, and we should not stick to a completely rigid subjective interpretation.Originality/valueThis study demonstrates the possible application of crime of sabotaging production and operation in cyberspace, and clarifies many misunderstandings about this crime.

Measurement invariance of the distress tolerance scale among university students with and without a history of non-suicidal self-injury.

Non-suicidal self-injury (NSSI) is the intentional damage to one’s body tissue in the absence of suicidal intent. NSSI primarily serves an emotion regulation function, with individuals engaging in self-injury to escape intense or unwanted emotion. Low distress tolerance has been identified as a mechanism that underlies self-injury, and is commonly assessed using the self-report Distress Tolerance Scale. There are mixed findings regarding the factor structure of the Distress Tolerance Scale, with some researchers utilising a higher-order distress tolerance score (derived from the scores on the four lower-order subscales) and other researchers using the four subscales as unique predictors of psychological outcomes. Neither of these factor structures have been assessed among individuals with a history of self-injury. Of note, an inability to tolerate distress (thought to underlie NSSI) may limit an individual’s capacity to accurately observe and report specific thoughts and emotions experienced in a state of heightened distress, which may impact the validity of scores on the Distress Tolerance Scale. Therefore, measurement invariance should be established before attributing NSSI-related differences on the scale to true differences in distress tolerance. We compared the Distress Tolerance Scale higher-order model with the lower-order four factor model among university students with and without a history of NSSI. Our results indicated that the lower-order four factor model was a significantly better fit to the data than the higher-order model. We then tested the measurement invariance of this lower-order factor model among individuals with and without a history of NSSI, and established configural and full metric invariance, followed by partial scalar and full residual error invariance. These results suggest the four subscales of the Distress Tolerance Scale can be used to confidently discern NSSI-related differences in distress tolerance.

Social Network Analytics for Supervised Fraud Detection in Insurance.

Insurance fraud occurs when policyholders file claims that are exaggerated or based on intentional damages. This contribution develops a fraud detection strategy by extracting insightful information from the social network of a claim. First, we construct a network by linking claims with all their involved parties, including the policyholders, brokers, experts, and garages. Next, we establish fraud as a social phenomenon in the network and use the BiRank algorithm with a fraud-specific query vector to compute a fraud score for each claim. From the network, we extract features related to the fraud scores as well as the claims' neighborhood structure. Finally, we combine these network features with the claim-specific features and build a supervised model with fraud in motor insurance as the target variable. Although we build a model for only motor insurance, the network includes claims from all available lines of business. Our results show that models with features derived from the network perform well when detecting fraud and even outperform the models using only the classical claim-specific features. Combining network and claim-specific features further improves the performance of supervised learning models to detect fraud. The resulting model flags highly suspicions claims that need to be further investigated. Our approach provides a guided and intelligent selection of claims and contributes to a more effective fraud investigationprocess.

Dynamic probability assessment of urban natural gas pipeline accidents considering integrated external activities

Urban gas pipelines usually have high structural vulnerability due to long service time. The locations across urban areas with high population density make the gas pipelines easily exposed to external activities. Recently, urban pipelines may also have been the target of terrorist attacks. Nevertheless, the intentional damage, i.e. terrorist attack, was seldom considered in previous risk analysis of urban gas pipelines. This work presents a dynamic risk analysis of external activities to urban gas pipelines, which integrates unintentional and intentional damage to pipelines in a unified framework. A Bayesian network mapping from the Bow-tie model is used to represent the evolution process of pipeline accidents initiating from intentional and unintentional hazards. The probabilities of basic events and safety barriers are estimated by adopting the Fuzzy set theory and hierarchical Bayesian analysis (HBA). The developed model enables assessment of the dynamic probabilities of consequences and identifies the most credible contributing factors to the risk, given observed evidence. It also captures both data and model uncertainties. Eventually, an industrial case is presented to illustrate the applicability and effectiveness of the developed methodology. It is observed that the proposed methodology helps to more accurately conduct risk assessment and management of urban natural gas pipelines.

Deliberate destruction or damage to another's property caused by arson in 1960-2018

One of the most important elements of the criminological characteristic of intentional destruction of property through arson is the quantitative and qualitative indicators of the commission of this crime, which include the level, structure, dynamics and geography. A full characterization of intentional destruction or damage to property by arson requires consideration of a number of criminological elements, including quantitative and qualitative indicators of intentional destruction or damage to property by arson, characterization of the offender committing intentional destruction or damage to property by arson, cause damage to property by arson. The article looks at statistics from 1960-2018 that reflect the level of crimes related to the deliberate destruction or damage to another's property by arson. The analysis is based on official statistics of the Interior Ministry of Ukraine. The focus is on the dynamics of reported crimes. The study of statistics from 1960-2018 on the deliberate destruction or damage of another's property by means of arson allows to obtain a considerable amount of useful information about the mechanism and means of arson, about the conditions and circumstances under which it was prepared and committed, the identity of the offender, etc. Identifying typical methods of arson can be the basis for developing versions, determining the direction of the investigation and the most appropriate ways to search the offender, establishing and further eliminating the circumstances contributing to the arson. The purpose and purpose of this article is to investigate statistics from 1960-2018 that reflect the results of the activities of law enforcement agencies in the detection of crimes related to the deliberate destruction and damage to property, including those committed by arson. The overall crime rate can be traced to the tables provided in the article. Investigations can form the basis of law-making activities, as well as serve as a basis for further scientific inquiries concerning the criminal-law characteristics of intentional destruction or damage to property.

Application of supervised learning to validation of damage detection

Unsupervised learning methods are effective and suitable tools for damage detection. The main reason for the popularity of these methods in structural health monitoring originates from the fact that the process of learning can be implemented by information of the only normal condition called training data. In contrast, supervised learning methods require information of both normal and current conditions for the process of interest. Because civil engineering structures are expensive and complex, it is not reasonable and economical to impose intentional damage on providing training data. Hence, it is not simple to directly exploit supervised learning techniques in structural health monitoring. To deal with this limitation, this article proposes a novel two-level strategy including three algorithms for using the concepts of both unsupervised learning and supervised learning. The major contribution of this strategy is to consider supervised learning as a validation tool for damage detection. First, the results of damage detection are obtained from two unsupervised learning methods developed by Mahalanobis squared distance and a deep autoencoder neural network in the first two algorithms of the proposed strategy. The main objective is to separate accurate and confusing results of damage detection based on Type I and Type II errors. Second, the confusing results are fed into the third algorithm to train a classifier and compute their classification margins for making the final decision and validating damage detection. The effectiveness and applicability of the proposed strategy are assessed by a numerical concrete beam and an experimental laboratory frame. Results show that this strategy with the aid of the Naive Bayes classifier enables the unsupervised learning methods to make accurate decisions.

Safety and security of oil and gas pipeline transportation: A systematic analysis of research trends and future needs using WoS

The terrorist attack on the Abqaiq oil plant in Saudi Arabia on September 14, 2019 attracted global attention to the significant role of safety and security in the sustainable oil and gas supply chain and the vulnerability of supply infrastructures subject to intentional and unintentional damages. Different from other oil and gas supply infrastructures, oil and gas pipelines may be more vulnerable to accidental, natural and intentional threats due to their widespread distribution. Therefore a systematic and thorough review is carried out to investigate safety and security of oil and gas pipelines based on bibliometric analysis. First, a total of 598 publications between 1970 and 2019 related to safety and security of oil and natural gas pipelines was retrieved and refined from the database of Web of Science (WoS). The 598 publications are analyzed by the bibliometric software VOSviewer to obtain the temporal and regional distribution of publications, to identify “productive institutions” and “productive authors”, and create the cooperation networks between institutions and authors. Besides, the evolution of research topics and research methods are identified based on keywords and bibliographic analysis. Moreover, the main research topics and research methods are analyzed to obtain insight into the research evolutions and trends. Risk assessment, leakage, and corrosion are the main topics while QRA, fuzzy theory and the Bayesian network are the most frequently used research methods. To further improve the sustainability of oil and gas pipelines, this study provides and discusses future research needs such as pipeline security, environmental sustainability, pipeline system resilience. According to these results, the research on risk assessment based on Bayesian network and consequence analysis using CFD may increase in the future. Besides, more research and guidelines on pipeline security, resilience, and environmental impacts to better protect pipelines, are expected.

Experimental and numerical analysis of failure in flexible pipe by a mechanism of intentional damage

The use of flexible pipe in onshore applications is now commonplace; however, there is scarce information on the modes of failure that affect its mechanical integrity, so its application in a transmission systems is risky and should require further analysis. An experimental- numerical study was performed to observe changes in the mechanical response and failure modes in this type of pipes. Pipe was perforated at a working pressure of 30 kg/cm2 (426.7 psi) to simulate experimentally the conditions generated when a hot tapping hole is illegally made to plunder petroleum products. It was found that the different pipe sections have a relatively low mechanical strength, especially the layer made of high density polyethylene. Tension and compression tests were carried out to obtain the appropriate technical data to perform static simulations, considering an external hole as the failure mechanism. After finite element modeling, it was found that flexible pipe presented an initial collapse in the HDPE inner layer at a pressure of 21.09 kg/cm2 (300 psi), which coincided with the experimental collapse induced by hot tapping drilling. This type of damage had not been studied in flexible pipelines for onshore applications. The information provided is useful in making decisions for the proper materials selection involved in the transport of hydrocarbons onshore.

HISTORY OF ESTABLISHMENT AND DEVELOPMENT OF UKRAINIAN LEGISLATION ON CRIMINAL LIABILITY FOR INTENTIONAL DESTRUCTION OR DAMAGE OF HOUSING-RESIDENTIAL HOUSING

The relevance of the article is that the history of the development of legal protection of housing and communal services cannot be separated from the history of legal protection of the institution of communal property in Ukraine as a whole. However, it still remains insufficiently studied. In the scientific literature there are only a few mentions of legal protection or property in general, which after 1990 was legally called communal and in the most characteristic features resembles this form of ownership, is its historical predecessor. Analysis of the most important sources of criminal law in Ukraine, which existed at one or another historical stage of its development, shows that at all times the state has consistently paid attention to the protection of communal property. The level of protection of these relations could be different, depending on the socio-economic, political and other conditions of society, but in this case the task of protecting communal property was performed by criminal law. Ensuring the inviolability of housing and communal services was carried out by criminal law, primarily by establishing liability for various encroachments on them as part of the institution of communal property. It was found that the criminal legislation of the second half of the XIX - early XX centuries. had a systematized nature, formed a system of rules on crimes related to the destruction and damage of housing and communal services, which has an extensive nature. The encroachment was differentiated according to the object, the features of the object and a number of other circumstances. It is determined that the current stage of development of criminal liability for destruction or damage to housing and communal services is associated with the adoption in 2001 of the new Criminal Code of Ukraine. It is concluded that initially the intentional destruction or damage of housing and communal services was treated in criminal law as a component of intentional destruction or damage to property, but later this phenomenon evolved into a separate crime. There is also an increase in the content of criminally punishable methods of intentional destruction or damage to housing and communal services.

Object of Intentional Damage to Communications Lines (Article 360 of the Criminal Code of Ukraine)

With regard to absence of thorough researches of objects of intentional damage to communications lines in criminal law theory, the purpose of this article is to study the conceptual foundations of such objects’ structure and content. Considering the specifics of the topic, goals and outlined objectives, various general scientific, special-scientific and philosophical methods were used for an objective study of the subject and for formation of sound conclusions. Among them, in particular, systematic method was used in studying objects of intentional damage to communications lines; dogmatic method – to identify shortcomings and explore the possibilities for improving of structure of objects of the crime stipulated by Art. 360 of the Criminal Code of Ukraine; logical-semantic – in the process of in-depth study of categorical-conceptual apparatus concerning the objects of intentional damage to communications lines. In order to ensure the formation of new proposals (based on already existing in special literature) and with regard to definition of structure of objects of intentional damage to communications lines, a method of generalization was applied. Scientific novelty. Certain problems of objects of the crime stipulated by Art. 360 of the Criminal Code of Ukraine have been studied. Unlike the activities of public authorities, local self-government bodies, and associations of citizens, intentional damage of communication lines does not involve the effectuation of organizational, administrative or administrative-economic functions; the purpose of this norm is to protect people when the subject commits a crime, in order to influence management relations. Therefore, the crimes of intentional damage of the communication lines do not coincide in the essence of public relations with other crimes, located in Chapter XV of the Special part of the Criminal Code of Ukraine. Therefore, it is advisable to place the norm about an intentional damage of communication lines in Chapter VI of the Special Part of the Criminal Code of Ukraine. It is argued that the structural elements of the social relations of the generic object of the crime provided for in Art. 360 of the Criminal Code of Ukraine, belong to: 1) participants (individuals and legal entities, society and state); 2) the subject of relations (property as a whole and property relations); 3) social connection (providing participants with these property protection relationships in general and property relations). Conclusions. It is argued that necessary to amend the Criminal Code of Ukraine (namely to place the Art. 360 of the Criminal Code of Ukraine in Chapter VI of the Special part “Crimes against property” by supplementing the law on criminal liability with Art. 194-2 of the Criminal Code of Ukraine). It is scientifically proven that the direct object of the crime under Art. 360 of the Criminal Code of Ukraine are public relations that provide protection of property as a whole and property relations. Direct main object of the crime stipulated by the Art. 360 of the Criminal Code of Ukraine is public relations in the sphere of ensuring of private, collective and state proprietary rights (depending on victim); additional obligatory object of the crime under inquiry is public relations providing normal functioning of telecommunication networks and its elements; additional optional object of the crime under inquiry could be public relations ensuring continuous proving telecommunication services, state defensive capacity, normal functioning of emergency response and civil defense services etc.

Effect of Endometrial Scratch on Heparin Binding Epidermal Growth Factor Level in Women Undergoing Intrauterine Insemination

Despite many improvements in Assisted reproductive techniques during the last three decades, clinical pregnancy and live-birth rates still nearly 30–40% and 20–30%, respectively. To enhance endometrial receptivity many attempts done one of the endometrial scratching could provoke delay in endometrial maturation reforms asynchrony between endometrium and the concepts and indeed induce wound healing by producing a considerable raise in the local secretion of pro-inflammatory cytokines and growth factors like Heparin Binding Epidermal Growth Factor (HBEGF) and its receptors has role in mediate the receptivity, maturation, and decidualization of endometrium and facilitates the implantation and development of both placenta and embryo. All women were undergone IUI procedure. They divided into two groups. Intervention group who did endometrial scratching by using pipelle catheter in luteal phase of preceding cycle and another blood sample aspirated before scratch. Control group include women without intervention of endometrial scratch. Both groups underwent controlled ovarian stimulation, triggering of ovulation and another blood sample was aspirated at day of IUI to measure level of HBEGF. 14 days later with luteal support, BHCG test underwent in blood to check pregnancy. Higher pregnancy rate among patients with scratch group (5/20) 25% than non-interventional group (3/25)12%. These result showed that HBEGF level in scratch group (386.1±124.7) is significantly higher than control group (279±189.3) as P-value was (0.035). Moreover, the HBEGF level at day of IUI (455.67±157.34) and in pregnant (563.9±163.66) is significantly higher than before scratch in scratch group (279.0±124.67), (406.26±138.89), as P-values were (0.00007, 0.049) respectively. Intentional local damage to the endometrium is a cost–effective procedure can be used to enhance the uterine receptivity that may help to overcome implantation failure problem.

Factors Associated with Non-Suicidal Self-Injury (NSSI) in Iran: A Narrative Systematic Review

Background: Non-suicidal (NSSI) refers to the intentional damage of one’s own body without a suicidal intent, which involves common behaviors such as cutting, burning, scratching, and hitting the body. Identifying factors associated with the development and continuity of NSSI is a research priority, as prevention is crucial. The aim of the current study was to determine factors associated with NSSI in Iran. Materials and Methods: In this systematic review, Persian databases including Barakat Knowledge Network System, Magiran, SID, and international databases including Scopus, Medline, and Web of Science were searched for relevant publications in English and Persian by using the following Medical Subject Headings search terms: self-injurious OR deliberate self-harm OR deliberate self-harm OR self-destructive behavior OR non-suicidal self-injury AND Iran: from 1983 until September 2019. Two independent reviewers studied the full text of the articles and extracted the main results. The results of studies were classified and presented descriptively with a narrative approach. Results: A total of 334 articles were found of which 18 articles (n= 17343) met the inclusion criteria and were reviewed. More than half of the reviewed articles were cross-sectional (n=16). Three main themes were identified: factors associated with baseline characteristics (such as age and gender); mental disorders (such as depression); and psycho-social factors associated with mental disorders (such as self-concept disturbance). Conclusion: The meaning of identified main themes shows that the most important factor in occurrence of NSSI in Iranian patients is mental health status. Since the majority of studies were cross-sectional, the data do not yet justify risk factors. Therefore, longitudinal studies with adequate methodological qualities are recommended in future studies.

ТЛУМАЧЕННЯ ТЕРМІНУ «КРИТИЧНО ВАЖЛИВИЙ ОБ’ЄКТ ІНФРАСТРУКТУРИ» ПРИ КВАЛІФІКАЦІЇ... КРИМІНАЛЬНИХ ПРАВОПОРУШЕНЬ

Currently, the term «critically important infrastructure object» in the articles of the Special Part of the Criminal Code of Ukraine occurs in part two and note of Article 259 and in note of Article 360. At the same time, its proper interpretation in law enforcement practice is very important for the correct qualification of the relevant actions of the person and for the appointment of punishment adequate to their social danger. This highlights the need for a comprehensive essential and substantive characteristics of the term based on current legislation. The purpose of the article is to develop, based on the analysis of current legislation, a clear understanding of the essence and meaning of the term «critically important infrastructure object» in order to ensure the correct application of criminal law norms in which this term is used. Critical infrastructure objects need enhanced protection because their decommissioning, or even a partial disruption, can have devastating consequences not only for the state’s economy but also for national security in general. Therefore, the state system of protection of critical infrastructure should be built in such a way as to protect these objects as much as possible from threats, including any illegal encroachments. To do this, the entire available arsenal of tools should be used, including the tools of criminal law. Ukraine, developing its own state system of critical infrastructure protection, focuses mainly on the most significant experience in this area gained by the United States and the European Union. At the same time, the European Union is the subject of special attention also because the Constitution of our state enshrines a strategic course for full membership in this integration entity. In the absence of a basic legislative act that would regulate all aspects of the functioning of the state system of critical infrastructure protection, the interpretation of the term «critically important infrastructure object» used in certain criminal law norms, which is identical to the term «critical infrastructure object», is based, first of all, on the provisions of the current Law of Ukraine «On Basic Principles of Cyber Security of Ukraine», but it is also necessary to refer to the bylaws of the Cabinet of Ministers of Ukraine and the NBU adopted for its implementation. In practice, when qualifying the actions of a person under part two of Article 259 of the Criminal Code of Ukraine to establish the belonging of the object of knowingly false information to critical infrastructure, it is necessary to determine whether this object is included in the national list of critical infrastructure objects, or to one of the nine sectoral lists, or to the consolidated list of banks, which are referred by the NBU to critical infrastructure in the banking system of Ukraine. In this case, the presence of the object in at least one of these lists is a necessary and sufficient condition. It is obvious that the same algorithm of actions is suitable for use in establishing the presence of serious consequences of intentional damage or destruction of the telecommunications network, when a person’s actions are qualified under part three of Article 360 of the Criminal Code of Ukraine, taking into account paragraph 2 of the note to this article. However, in order to imperatively consolidate this approach, it is proposed to place in the note to this article, by analogy with Article 259 of the Criminal Code of Ukraine, a reference to the Law of Ukraine «On Basic Principles of Cyber Security of Ukraine».

SCYTHIAN GRAVE OF THE MOUND ORLYKOVA MOHILA IN THE SOUTH OF KIROVOGRAD REGION

The article publishes research materials of the Scythian burial intake from the excavations of the mound Orlikova Mogila near the village Bogdanovka, Bobrynetsky district of Kirovograd region (Northern part of the Black Sea Right-Bank Steppe). The grave was built in an earlier mound of the Bronze Age.
 The Bronze Age burial was located in the center and completely destroyed by Scythian grave. After the Scythian burial, the embankment was significantly enlarged, and also strengthened by stone krepida.
 By the time of the excavation, the mound had a height of more than 3.0 m and a diameter of more than 30 m.
 Scythian tomb had dimensions of 4 Ч 3 m and a depth of 2.8 m. From above it was covered with wooden deck and stone laying.
 Despite the devastating repeated robberies, the monument contains artifacts that can be interpreted as grave of a heavily armed warrior — man of 30—50 years old with a high social status. The deceased was accompanied by two dependent persons. Fragments of a metal shell made of plates, arrowheads, and fragments of two antique amphorae were found in the grave.
 Of great interest are the finds of bronze parts of a horse harness, located among the stones on the embankment. All these objects have traces of intentional damage, which, undoubtedly, is associated with a certain funeral ritual.
 Found objects, especially fragments of ancient amphorae, date the Scythian grave at the end of the 5th century BC.
 The appearance of such structures in the mounds of the Scythian pores in the northern limits of the steppe Black Sea region, apparently, should be associated with the promotion of Scythian nomads from the more southern regions

Non-Suicidal Self Injury: Indian Perspective

Self-injurious behavior or deliberate self-harm (DSH) in adolescents and young adults is an area of growing concern. Reports from clinics and emergency rooms are pointing to the increase in incidence. However, there are very few studies from India. Many of the people presenting with acts of self-harm do not have suicidal intent, and this has prompted the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5)[1] to propose a category of Nonsuicidal Self-Injury (NSSI) as a “Condition for Further Study” to encourage further research in this area. DSM-5 Proposed Criteria for NSSI requires an individual to engage in intentional self-inflicted damage to the surface of his/her body, on 5 or more days in the last 1 year, with the expectation that the injury will lead to only mild or moderate physical harm. NSSI is defined as ‘intentional destruction of one’s body tissue without suicidal intent’.

Practical security of continuous-variable quantum key distribution with reduced optical attenuation

In a practical CVQKD system, the optical attenuator can adjust the Gaussian-modulated coherent states and the local oscillator signal to an optimal value for guaranteeing the security of the system and optimizing the performance of the system. However, the performance of the optical attenuator may deteriorate due to the intentional and unintentional damage of the device. In this paper, we investigate the practical security of a CVQKD system with reduced optical attenuation. We find that the secret key rate of the system may be overestimated based on the investigation of parameter estimation under the effects of reduced optical attenuation. This opens a security loophole for Eve to successfully perform an intercept-resend attack in a practical CVQKD system. To close this loophole, we add an optical fuse at Alice's output port and design a scheme to monitor the level of optical attenuation in real time, which can make the secret key rate of the system evaluated precisely. The analysis shows that these countermeasures can effectively resist this potential attack.
