IoT forensics: Exploiting unexplored log records from the HIKVISION file system

CCTV surveillance systems are IoT products that can be found almost everywhere. Their digital forensic analysis often plays a key role in solving crimes. However, it is common for these devices to use proprietary file systems, which frequently hinders a complete examination. HIKVISION is a well-known manufacturer of such devices that typically ships its products with its proprietary file system. The HIKVISION file system has been analyzed before but that research has focused on the recovery of video footage. In this paper, the HIKVISION file system is being revisited regarding the log records it stores. More specifically, these log records are thoroughly examined to uncover both their structure and meaning. These unexplored pieces of evidence remain unexploited by major commercial forensic software, yet they can contain critical information for an investigation. To further assist digital forensic examiners with their analysis, a Python utility, namely the Hikvision Log Analyzer, was developed as part of this study that can automate part of the process.     

Psychopathy among condemned capital murderers

Psychopathy is an important forensic mental health construct. Despite this importance, the research base of psychopathy among individuals convicted of capital murder is limited. Archival data were collected from a sample of 636 persons convicted of capital murder and sentenced to death in the State of California. Psychopathy was assessed using the Psychopathy Checklist – Revised (PCL-R) instrument. Data on criminal careers and other behavioral disorders were also extracted. The sample mean PCL-R total score was 23.31 (SD = 9.92) and one-third of individuals in this sample were considered clinically psychopathic with PCL-R total scores of 30 or greater. Factor analytic examination yielded support for four facets: affective, interpersonal, lifestyle, and antisocial. Criterion validity findings revealed positive correlations of psychopathy scores with Antisocial Personality Disorder (ρ = 0.72), Conduct Disorder (ρ = 0.46), sexual sadism (ρ = 0.24), Oppositional Defiant Disorder (ρ = 0.20), ADHD (ρ = 0.15), arrest charges (r = 0.56), prison sentences (r = 0.53), and age of arrest onset (r = −0.57). Individuals convicted of capital murder and sentenced to death reflect heterogeneity in psychopathy with some individuals exhibiting pronounced psychopathic features.     

Accuracy of comparison decisions by forensic firearms examiners

This black box study assessed the performance of forensic firearms examiners in the United States. It involved three different types of firearms and 173 volunteers who performed a total of 8640 comparisons of both bullets and cartridge cases. The overall false-positive error rate was estimated as 0.656% and 0.933% for bullets and cartridge cases, respectively, while the rate of false negatives was estimated as 2.87% and 1.87% for bullets and cartridge cases, respectively. The majority of errors were made by a limited number of examiners. Because chi-square tests of independence strongly suggest that error probabilities are not the same for each examiner, these are maximum-likelihood estimates based on the beta-binomial probability model and do not depend on an assumption of equal examiner-specific error rates. Corresponding 95% confidence intervals are (0.305%, 1.42%) and (0.548%, 1.57%) for false positives for bullets and cartridge cases, respectively, and (1.89%, 4.26%) and (1.16%, 2.99%) for false negatives for bullets and cartridge cases, respectively. The results of this study are consistent with prior studies, despite its comprehensive design and challenging specimens.     

China–Pakistan Economic Corridor (CPEC) development projects and entrepreneurial potential of locals

This research explores a very important issue arising from the initiation of China–Pakistan Economic Corridor (CPEC) in Pakistan, as the major impact seems to be focused towards small businesses and how they will cope in this competitive market once Chinese businesses enter in the country. According to scholars and officials, CPEC will generate several business opportunities for the local Pakistani community. However, studies related to the CPEC project are limited and only focused on the development of the CPEC project in various aspects alone. The existing study examined the local entrepreneur's attitude and intention in the context of CPEC using a sample of 255 survey questionnaires. Structural equation modeling was used to test the proposed hypotheses. Data were gathered from the existing business community in Karachi, Pakistan. The results validated most of the hypotheses showing positive attitude towards entrepreneurs and intention towards CPEC development project. Specifically, local transportation and accessibility of cities show a significant relationship with a positive attitude. Similarly, the attitude of entrepreneurs also shows a positive relationship with entrepreneur's intention towards CPEC development projects. Findings have important theoretical and practical implications for policymakers of CPEC in creating an overall entrepreneurial ecosystem.     

A semiotic analysis of intergeneric borrowings in print advertisements in Jordan

This paper presents a semiotic analysis of Arabic print advertisements in Jordan. In particular it investigates the phenomenon of intergeneric borrowings. The focus of the study is to provide interpretation of the connoted meanings of these borrowings in light of the sociocultural context that has given rise to them. It also aims to show how these borrowings and the other signs intersemiotically complement each other to achieve their communicative function. To this end, a variety of print advertisements were collected from three major daily newspapers in Jordan, Al-Rai, Ad-Dustour, and Al-Ghad. The analysis draws on Chandler's model of semiotic analysis. The analysis has revealed that the borrowings in the sample data represent specific values derived from the viewers’ sociocultural and ideological repertoire. Some of them have the functions of building rapport through creating a celebrative or humorous atmosphere, word play, word replacement, and ambiguity connoted by references to popular culture and mundane situations, while some have the function of creating credibility, commitment, and morality through references to religious discourse and cultural memory.     

The corporate political strategy and its integration with market strategy in transitional China

• The paper provides an integrated strategy framework of political and market strategy aiming to respond to the external environment including political issues: (1) In strategic analysis stage, firm should incorporate non‐market issue analysis, selection and evaluation mechanism; (2) In strategic choice stage, firm should expand its strategic choice scope into political fields. The paper actually explores the taxonomy of CPS in transitional China; (3) Firm should pay attention to the integration between political strategy and market strategy. Finally, some theoretical and practicing implications are provided.

Corporal Punishment of Children: A Multi-Generational Perspective

This paper presents a study on the self-reported usage and attitudes toward corporal punishment (CP) by a four generation sample of Jewish families in Jerusalem. The study included 655 participants: 200 adolescents, 208 young mothers, 199 old mothers, and 48 grandmothers, and tested for inter-generational and familial role differences. Results have shown that participants’ attitudes toward CP correlates significantly with age group; however, it does not correlate with family role. Implications of the results for practitioners who seek to reduce usage of CP are suggested.

On the Lived Experience of Battered Women Residing in Shelters

We present a qualitative study of battered women, which examined their experiences while staying at shelters. In-depth, semi-structured interviews were conducted with 18 battered women staying at shelters. The interviews elicited four main themes: the women’s perceptions of the shelter; the woman’s perceptions of herself and her life experiences; the woman’s perceptions of her relations with other battered women at the shelter; and the woman’s perceptions of her relations with the staff of the shelter. The paper concludes with a discussion of the limitations of the study, implications for future research, implications for theory development, and implications for therapy and intervention with the problem of wife battering.
