Static Nature

Purpose The purpose of this paper is to analyze the design and implementation of the police crackdown strategy employed in Mexico City and to discuss its limitations toward a medium-to-long-term reduction of crime rates for six types of robberies. Design/methodology/approach The present work employs generalized autoregressive conditional heteroscedasticity (GARCH) models to estimate the effect of police operations on the volatility of the rates of six types of robberies in Mexico City, as well as their persistence over time. Findings Results suggest that the concentration of policing in certain high-criminality spaces reduces crime rates in the immediate term; however, its permanence is contingent on policing design and behavioral characteristics of the targeted crime. Specifically, the Mexico City police crackdown strategy seems to be better suited for combating crimes of a “non-static” nature than those of a “static” nature. Research limitations/implications Due to the nature of the data used for this research, the performed analysis does not enable a precise determination of whether the crime rates respond to temporal or spatial displacement. Practical implications Considering the obtained results, a re-design of Mexico City’s police crackdown strategy is suggested for the sustained reduction of the number of reported cases of robberies of a static nature. Originality/value Despite their importance, few studies have measured the impact of police crackdowns on city-level crime rates and whether their effect is temporary or permanent. The present study proposes the use of GARCH models in order to integrate the study of this phenomenon into criminal time series models.

Complex Eigenvalues

Purpose Discrete eigenvalues occur in eddy current problems in which the solution domain was truncated on its edge. In case of conductive material with a hole, the eigenvalues are complex numbers. Their computation consists of finding complex roots of a complex function that satisfies the electromagnetic interface conditions. The purpose of this paper is to present a method of computing complex eigenvalues that are roots of such a function. Design/methodology/approach The proposed approach involves precise determination of regions in which the roots are found and applying sets of initial points, as well as the Cauchy argument principle to calculate them. Findings The elaborated algorithm was implemented in Matlab and the obtained results were verified using Newton’s method and the fsolve procedure. Both in the case of magnetic and nonmagnetic materials, such a solution was the only one that did not skip any of the eigenvalues, obtaining the results in the shortest time. Originality/value The paper presents a new effective method of locating complex eigenvalues for analytical solutions of eddy current problems containing a conductive material with a hole.

The Impact

In recent years, human capital has become increasingly emphasized as a factor of economic growth. Managing human capital could stimulate the whole economy to better performance in competitiveness. Although these indicators include several variables, there is no precise determination of which indicator mostly affects the country's economic growth. This paper summarizes the knowledge and approaches of several authors in the field of economic growth, knowledge economy, competitiveness, innovations and individual elements affecting these areas. It outlines the findings and provides some insight into the impact of individual factors on economic growth across recent studies. The main goal is to obtain information about the impact of education, its support, and its influence on economic performance on the example of empirical data documenting the qualitative parameters of the workforce. The use of selected indicators indicated their impact on the change in economic performance. The partial objective is to identify an indicator or set of indicators that could express the impact of human capital on economic growth. The study involved research methods such as analyzes, statistical methods such as correlation and p-value, and prediction for the next period based on past developments. The research object is the V4 countries – the Czech Republic, Slovakia, Hungary, and Poland. The findings pointed to the strong impact of the analyzed factors on economic growth. Besides, they showed which of the known ways to increase the efficiency of the labor factor were actually or little used in the sample countries. Undoubtedly, there is also an indicative and interesting comparison within a group or with other economies at a comparable economic and social development level. Finally, improvements to the current situation were proposed. The systematization of literary sources and approaches to economic growth helps identify possible proposals for improving competitiveness in the future, using innovative approaches.

The Impact

PurposeThe primary purpose of this paper is to empirically investigate the impact of educational attainment on crime rates across 33 Indian states over the period 2001 to 2013. This paper also examines the role of various macroeconomic, socio-economic and demographic factors in determining the variation of crimes in India.Design/methodology/approachFirst, this paper provides a representative theoretical model and discusses the possible relationship between crime and education. Second, the paper applies a dynamic panel data (DPD) model to extract more precise, unbiased and reliable estimates of the effect of education in abating different crime rates. The main advantage of using the dynamic panel model is to address the problem of endogeneity in some regressors and capture the time persistent effect of education on crime.FindingsEmpirical findings reveal that a 1% increase in gross enrolment ratio leads to the reduction of total crime by 8%. However, a unique finding identifies a positive association between tertiary education and economic crime. This finding further goes against the general belief that criminals tend to be less educated than non-criminals.Practical implicationsThis paper recommends that instead of punishment and mandatory law enforcement for offenders, increase in government expenditure and different educational attainment ratios can go a long way to combat crime in India, which has posed a serious threat to the stability of society. Furthermore, utilizing the information on offenders' educational attainment in examining the crime rates can be a future research agenda for policymakers.Originality/valueThis study contributes to the empirical debate of ‘crime-education nexus’ by examining the role of education on crime in India. This study is the first of its kind that focuses on the aspects of crime and education more recently and investigates the relationship between crime and education due to the recent changes in educational attainment ratios and crime rate.

The Impact

Purpose – The purpose of this paper is to examine the impact of the Jordanian anti-money laundering law and its instructions on the Jordanian banking industry. The anti-money laundering law in Jordan is newly enacted, but there are new developments not covered by the law. For instance, the revolutionary wave known as the Arab Spring surrounding Jordan has increased the crime rates in Jordan, and it has also reduced international coordination and cooperation to encounter money laundering operations. The emergence of new means for money transfer is affecting the efficiency and speed of bank transfers. Subsequently, the impact of the law on Jordanian banks is unknown. Design/methodology/approach – This paper relies on the Jordanian Anti-Money Laundering and Counter Terrorist Financing Law 2007 as a primary source of information. The relevant Jordanian anti-money laundering instructions that have directly been affecting banks include the Jordanian Anti Money Laundering and Counter Terrorist Financing Instructions Number (51) 2010. These instructions were considered the most important legislation for the purpose of this paper. Findings – While the Jordanian anti-money laundering law is based on certain principles, the effectiveness of the law is unknown. The Arab Spring, particularly the Syrian revolution, has negatively increased the crime rates and money laundering activities in Jordan. To make matters worse, the international cooperation and coordination between countries in combating money laundering are not at the required level, and this has encouraged money laundering groups to exploit the situation. Only time will tell whether the banks will be able to cope sufficiently with the increased anti-money laundering obligations. Obviously, it is critical at this stage to establish effective coordination between legislators, regulators and the banking industry to minimize problems encountered by the banks, thereby to ensure effective implementation of the law. Originality/value – This paper provides an examination of the impact of the Jordanian anti-money laundering law that has directly affected banks. It is hoped that this paper would provide some insight into this particular area for academics, practitioners, the legal advisers, banks and policy-makers not only in Jordan but also elsewhere. In view of the international nature of money laundering and banking, there will be significant interest in how the anti-money laundering law affects banks operation in Jordan.

Subject The impact of the 'gag rule'. Significance US President Donald Trump on January 23 re-instated the 1984 Mexico City Policy, which prevents US family planning funding from going to foreign organisations that give information about abortion, and expanded it to include all US funding assistance. Known as the ‘global gag rule’, the policy is likely to end up restricting funding for women's health services in general. Impacts The inadvertent effects of the gag rule-- eg, unsafe abortions -- could in principle be offset by higher funding for contraceptive services. However, such an increase in funding is unlikely to occur. This is set to reverse gains in maternal mortality globally.

Purpose This study aims to examine the unexpected portion of the pension discount rate to determine if the pension discount rate is being used to manage earnings for both financially healthy and financially unhealthy firms as categorized based upon their Altman z-score for bankruptcy. Design/methodology/approach Regression analysis is conducted with the unexpected portion of the pension discount rate as the dependent variable and various metrics indicating potential firm strengths and weaknesses as the independent variables. Findings This study finds evidence that suggests managers for both groups of firms are using their choice of discount rate to manage bottom-line earnings. These findings highlight the patterns of various firm choice differences found between the two groups and the magnitude of the differences between the groups. Originality/value Three streams of literature are considered in this research: earnings management, defined pension plans and z-score bankruptcy. This study extends prior research by examining the unexpected portion of the pension discount rate based on the z-score determination of whether a firm is considered financially healthy or financially unhealthy. Our findings highlight the impact of various firm choice differences found between the two groups of firms.

✓ Methods for localizing the posteroventral globus pallidus internus are described. The authors' techniques include the use of microelectrodes to record single-unit activity and to microstimulate in human pallidum and its surrounding structures. This technique allows a precise determination of the locations of characteristic cell types in sequential trajectories through the external and internal segments of the pallidum. The location of the optic tract can be determined from microstimulation-evoked visual sensations and recordings of flash-evoked potentials. In addition, microstimulation-evoked motor and sensory responses allow the internal capsule to be identified. The data collected using this technique are an important adjunct to selecting optimum sites to place electrocoagulation lesions for stereotactic posteroventral pallidotomy for refractory Parkinson's disease.

PurposeThe purpose of this research is to analyse the influence of mobile word of mouth (m-WOM), received at the physical store, which “challenges” the consumer's preferences in a webrooming experience. The impacts of the social relationship between the sender and the receiver of the m-WOM and product category (electronics versus fashion accessories) are examined.Design/methodology/approachAn online experiment was carried out which manipulated the presence and type of challenging m-WOM, and product category, in a 3 × 2 between-subjects factorial design. The participants were 204 consumers recruited through a market research agency. Their perceptions about the helpfulness of the m-WOM, and their product preferences and choices, were analysed.FindingsReceiving in-store m-WOM was perceived as helpful by webroomers and affected their preferences and choices. For electronics online reviews posted by anonymous customers were more influential than friends' opinions, whereas the opposite was the case with fashion accessories. The trustworthiness and expertise of the m-WOM source may explain the effects of m-WOM.Practical implicationsm-WOM entails challenges and opportunities for retailers in the omnichannel era. The findings suggest that allowing customers to access m-WOM may be beneficial; however, retailers must consider the type of m-WOM that may be most suitable for their businesses. Recommendations for referral and review sites are also offered.Originality/valueThis study examines the impact of challenging m-WOM on shopping experiences, combining online, mobile and physical channels. The results revealed the importance of the information source and product category in the determination of consumers' perceptions of helpfulness, preferences and choice.

Purpose There is a lack of understanding in the literature on the relation between parks and house price in relation to crime in Scandinavian context. This paper aims to investigate the effect of the amenity value of accessibility to parks on apartment prices with reference to crime rates in parks in Stockholm. Design/methodology/approach This paper analyses the effects of park proximity and crime in parks on apartment prices by using geographic information systems and hedonic modelling. Findings Findings show that the proximity of parks as an environmental amenity has an effect on apartment prices. The results also demonstrate that the impact of parks on apartment prices is different in the different segments of the apartment market in Stockholm. Moreover, various types of parks may differ in their impact, for instance, grass parks and park blocks are more desirable in Stockholm than landscape parks and neighbourhood parks. The effects of crimes in parks influence apartment prices negatively. Originality/value This paper provides a new methodology by using the shortest distance to a park as a main variable. The shortest distance to a park variable is considered a better choice than using park as an aggregate measure. To the best of the author’s knowledge, this is the first study that investigates the effect of specific park types, for instance, grass parks, neighbourhood parks, landscape parks and park blocks, in Stockholm housing market.

The Impact

Purpose Because that the crime in a wide way impacts the life of the people in the big metropolis, researchers have treated the question from several angles. The purpose of the paper, under the umbrella of operational research, is to develop a model of the ordering of police strategies, in the fight against crime in general, according to a certain criminal demand. Design/methodology/approach For the construction of the impact matrix of the strategies under the reduction of crime rates, considering a portfolio of crimes, a questionnaire applied to specialists was used. In a second moment, defined the criteria and strategies to be ordered, the multicriteria ELECTRE IV method was used, which with the help of the J-Electre software emulated the systematized data in the impact matrix and produced the final ordering of the most efficient strategies, in the fight against crime, in the perception of decision-makers. Findings As a result, the research revealed that policing strategies directed at solving specific crimes are the most effective in the perception of decision-makers after the emulation of data with the ELECTRE IV method. Research limitations/implications As research implications, it can be inferred that the use of multicriteria methods in the modeling of problems in the area of public security can contribute to rationalization of the use of the means available in the fight against crime in large cities. The research showed that it is possible to use customized policing strategies to a certain reality. Practical implications The method presented in this research is directly related to the major strategies: problem-oriented policing and hot spot policing. This method allows public safety managers to consider the possibility of combining different law enforcement strategies in each context. In this sense, the use of the multiple-criteria decision analysis (MCDA) (ELECTRE IV) method allows the evaluation of a large set of alternatives according to a set of established criteria, speeding up the process and reducing subjectivity, allowing the manager to analyze several scenarios with greater clarity and impartiality and choosing an alternative that best solves the proposed problem. The expected result is the rationalization of the available means applied in the search for the reduction of crime rates. Social implications The customization of policing strategies, according to criminal demands, implies the efficient way to reduce criminal charges. Reducing criminal rates enables the development of the local economy, tourism and the quality of life of people by exercising their freedom to the full. Originality/value The originality lies in filling a gap in the literature with the elaboration of the impact matrix of policing strategies in reducing criminal indices, and in their associated use in ordering strategies through a multicriteria method.
