Size isn't everything: Understanding the relationship between police workforce and crime problems

If and how policing affects crime has long been studied. On the relationship between police force size and crime, different authors come to different conclusions. This study examines the relationship between police resourcing, including workforce size, structure and stability over time using data for 42 police forces in the UK over a 13-year period.We construct two novel panel datasets. The first comprises measures of police workforce Size, Structure and Stability. The second provides measures of both crime frequency and crime severity. Issues of endogeneity make the modelling of the police-crime association complicated. Consequently, we analyse the data using a panel vector autoregression (PVAR) model which is capable of forecasting a temporal sequence of the interdependencies between police-crime relationships.Changes in total police personnel play an important role in reducing both crime frequency and severity, but the findings are more nuanced than this. Results highlight that the structure and stability of police organisations are important although these impacts are not always the same for crime volume and crime severity. We find that increases in frontline (non-sworn) support staff are associated with reductions in crime, while turnover rates of police staff are associated with increases in crime. In contrast, changes to the number of sworn police officers do not appear to be a good predictor of crime volume.The findings suggest that investment in frontline support staff and the development of strategies to retain skills and knowledge by reducing staff turnover may be efficient approaches for Police Forces to maximise the impact on crime of their workforce in resource-pressed policing settings. While previous research has found that police force size has a limited effect on crime, our findings indicate that more nuanced measurements of police resourcing are necessary to understand how police impact upon crime risk. The idea of police forces using basic officer-to-population ratios to make staffing decisions appears outdated and over-simplistic.

EFFICIENCY OF MONETARY POLICY IMPLEMENTATION AS A BASIS FOR CENTRAL BANK STABILISATION POLICY UNDER MARTIAL LAW (UKRAINIAN AND ISRAELI PRACTICES)

The purpose of the paper is to summarise and present the anti-crisis practices of a central bank during martial law in the country, based on the experience of the National Bank of Ukraine and the Bank of Israel. The research methodology is based on an analysis of reports, guidelines, statistical data, scientific articles, legislation bases, and other relevant materials. One of the methodological aspects of this study is a comparison of the knowledge acquired about the regulations implemented by the two central banks after the introduction of martial law in the countries. The objective is to identify potential lessons learned for the banking regulations of Ukraine and the State of Israel. The results of the study show that the practical implementation of stabilisation measures by central banks is crucial for achieving financial stability of the state both during and after wartime, as well as the ability to predict possible deepening of crises and minimise their consequences. The tools and methods used by these central banks differ. In particular, the NBU's main monetary policy instrument was foreign exchange interventions, while the BoI actively used the key policy rate. The proper formation of international currency reserves and the possibility of using them during a war-related crisis is critical for both countries. This fact confirms that crisis management has different types of scenarios. Each anti-crisis scenario is unique. This paper highlights the practical need for interaction between monetary and macroprudential policies of the central bank in wartime. It demonstrates various combinations of methods and instruments of the central bank's monetary policy. This study also shows the interdependence of the economies of these two countries. Practical implementation. This analysis provides insight into the anti-crisis activities of central banks during unpredictable periods in a country's life, namely, during martial law. At the present stage, banking systems do not often face the challenges of war. Therefore, studying each case is important for improving theoretical knowledge and deepening practical research. Value / Originality. The author of the study collected the experience and practices of stabilisation activities of the central banks of Ukraine and Israel during the war.

Individual differences in proprioceptive reorientation: a study on body characteristics and Posturography

ABSTRACT Spatial reorientation guided by the proprioceptive information derived from walking on a slanted floor has revealed large individual and sex differences. Here we addressed the role of body characteristics and measures of stability and balance-related sensory function from computerized dynamic posturography. Blindfolded participants walked in a slanted arena and had to identify the uphill direction (Perceptual task) and use the slope to remember the location of a target object (Memory task). Male participants performed better in the Perceptual task. In the Memory task, heavier participants made smaller errors, suggesting that body mass may influence how we navigate in the environment.

Differences in Trunk Acceleration-Derived Gait Indexes in Stroke Subjects with and without Stroke-Induced Immunosuppression.

Background: Stroke-induced immunosuppression (SII) represents a negative rehabilitative prognostic factor associated with poor motor performance at discharge from a neurorehabilitation unit (NRB). This study aims to evaluate the association between SII and gait impairment at NRB admission. Methods: Forty-six stroke patients (65.4 ± 15.8 years, 28 males) and 42 healthy subjects (HS), matched for age, sex, and gait speed, underwent gait analysis using an inertial measurement unit at the lumbar level. Stroke patients were divided into two groups: (i) the SII group was defined using a neutrophil-to-lymphocyte ratio ≥ 5, and (ii) the immunocompetent (IC) group. Harmonic ratio (HR) and short-term largest Lyapunov's exponent (sLLE) were calculated as measures of gait symmetry and stability, respectively. Results: Out of 46 patients, 14 (30.4%) had SII. HR was higher in HS when compared to SII and IC groups (p < 0.01). HR values were lower in SII when compared to IC subjects (p < 0.01). sLLE was lower in HS when compared to SII and IC groups in the vertical and medio-lateral planes (p ≤ 0.01 for all comparisons). sLLE in the medio-lateral plane was higher in SII when compared to IC subjects (p = 0.04). Conclusions: SII individuals are characterized by a pronounced asymmetric gait and a more impaired dynamic gait stability. Our findings underline the importance of devising tailored rehabilitation programs in patients with SII. Further studies are needed to assess the long-term outcomes and the role of other clinical features on gait pattern.

Design and Psychometric Evaluation of Nurses' Mobile Health Device Acceptance Scale (NMHDA-Scale): Application of the Expectation-Confirmation Theory.

The use of mobile tools in nursing care is indispensable. Given the importance of nurses' acceptance of these tools in delivering effective care, this issue requires greater attention. This study aims to design the Mobile Health Tool Acceptance Scale for Nurses based on the Expectation-Confirmation Theory and to evaluate it psychometrically. Using a Waltz-based approach grounded in existing tools and the constructs of the Expectation-Confirmation Theory, the initial version of the scale was designed and evaluated for face and content validity. Construct validity was examined through exploratory factor analysis, concurrent validity, and known-group comparison. Reliability was assessed using measures of internal consistency and stability. The initial version of the scale consisted of 33 items. During the qualitative and quantitative content validity stage, 1 item was added and 1 item was removed. Exploratory factor analysis, retaining 33 items, identified 5 factors that explained 70.53% of the variance. A significant positive correlation was found between the scores of the designed tool and nurses' attitudes toward using mobile-based apps in nursing care (r=0.655, P<.001). The intraclass correlation coefficient, Cronbach α, and ω coefficient were 0.938, 0.953, and 0.907, respectively. The 33-item scale developed is a valid and reliable instrument for measuring nurses' acceptance of mobile health tools.

Improving Threshold for Fault-Tolerant Color-Code Quantum Computing by Flagged Weight Optimization

Color codes are promising quantum error-correction (QEC) codes because they have an advantage over surface codes in that all Clifford gates can be implemented transversally. However, the thresholds of color codes under circuit-level noise are relatively low, mainly because measurements of their high-weight stabilizer generators cause an increase in the circuit depth and, thus, substantial errors are introduced. This makes color codes not the best candidate for fault-tolerant quantum computing. Here, we propose a method to suppress the impact of such errors by optimizing weights of decoders using conditional error probabilities conditioned on the measurement outcomes of flag qubits. In numerical simulations, we improve the threshold of the (4.8.8) color code under circuit-level noise from 0.14% to around 0.27%, which is calculated by using an integer programming decoder. Furthermore, in the (6.6.6) color code, we achieve a circuit-level threshold of around 0.36%, which is almost the same value as the highest value in the previous studies employing the same noise model. In both cases, the effective code distance is also improved compared to a conventional method that uses a single ancilla qubit for each stabilizer measurement. Thereby, the achieved logical error rates at low physical error rates are almost one order of magnitude lower than those of the conventional method with the same code distance. Even when compared to the single-ancilla method with a higher code distance, considering the increased number of qubits used in our method, we achieve lower logical error rates in most cases. This method can also be applied to other weight-based decoders, making the color codes more promising as candidates for the experimental implementation of QEC. Furthermore, one can utilize this approach to improve a threshold of wider classes of QEC codes, such as high-rate quantum low-density parity-check codes.

Influence falling income inequality for social stability: Case study of four European countries

AbstractThis study aims to assess the relationship between income inequality and social solidarity as a measure of societal stability, using European countries as a case study. Data from 20 European countries were included in the research. The primary dependent variable was defined as social solidarity, serving as an indicator of societal stability. The analysis of social solidarity was conducted concerning various social groups, including overall solidarity and solidarity towards vulnerable societal categories. Responses to questions were evaluated using the Likert scale. Income inequality within each country, measured by the Gini coefficient, was designated as the explanatory variable. Control variables were incorporated, including GDP per capita and the percentage of social expenditure relative to a country's GDP. The conducted analysis demonstrates a negative correlation between income inequality and the manifestation of social solidarity. The analysis of individual characteristics reveals that specific groups exhibit greater social solidarity compared to others. The conclusion drawn is that both lower and higher household income levels lead to a decrease in the overall manifestation of social solidarity in the face of increasing income inequality. The study's findings contribute theoretically to the discourse on income inequality and its impact on societal stability.

Economic Analysis of the Export Trends of Livestock and Livestock Products in India

Livestock provides livelihood to two-third of rural masses and employs about 8.8 per cent population of India. While dairying ensures livelihood to 70 million farm families. The study utilized export data from government sources and conducted a statistical analysis to assess trends and stability. Data revealed that the overall export value increased significantly from ₹22,092.62 crore in 2011-12 to ₹48,947.55 crore in 2021-22, reflecting a compound annual growth rate (CAGR) of 4.90%. Buffalo meat emerged as the leading export product, while dairy products exhibited a notable growth rate while dairy products and other categories showed varied growth. The instability index for the total exports was 19.02%, indicating moderate stability. State-wise analysis indicated Uttar Pradesh as the leading exporter, followed by Maharashtra and Haryana, with these three states together accounting for 85% of the total exports in 2021-22. The average growth rate of exports across states was 3.57%, demonstrating a stable growth pattern. Despite challenges posed by the COVID-19 pandemic, the sector showed resilience with a 13.98% growth in exports for 2021-22, aided by government initiatives. The analysis of dairy product exports highlighted a significant increase from ₹2,382.91 crore in 2020-21 to ₹4,742.70 crore in 2021-22, marking a 99% growth. The primary export destinations were the USA, Bangladesh, UAE, Saudi Arabia, Bahrain, and Malaysia. A transitional probability matrix revealed shifts in market shares, with notable increases in the USA and Bangladesh. Trade performance from 2011-22 showed that India's export share in dairy products improved from 0.03% to 0.135%, while import share decreased significantly. The instability index for exports was 63.53%, reflecting high volatility. Investing in advanced breeding technologies to increase productivity, and enhancing market access through trade agreements and promotional activities. Additionally, policies to manage volatility, such as price stabilization measures and export incentives, could further support industry growth.

Going straight home? Housing stability and post-prison reoffending in Aotearoa New Zealand

ABSTRACT International research has found that post-release stable accommodation is associated with reduced recidivism, however, research exploring this relationship in Aotearoa New Zealand and its potential causal nature is limited. Drawing on quantitative pre- and post-release interviews with people released from prison in Aotearoa New Zealand, this article examines their housing situations and the relationship between two measures of recidivism (re-sentencing and re-imprisonment) and two measures of housing stability (stable housing and residential mobility). Whilst stable housing is associated with a reduced risk of re-imprisonment, after controlling for confounding variables using inverse probability of treatment weighting, a direct causal relationship between housing stability and recidivism could not be found. We conclude that housing stability is therefore likely to be indicative of broader stability post-release and supports other factors related to successful reintegration, including the development of social capital.

Shaping coastal nature-based solutions: Perceptions and policy priorities of living shorelines

Coastal nature-based solutions, such as living shorelines, are promoted as shoreline stabilization alternatives to hard infrastructure in the United States. In the state of Florida, where sea level rise and increasing storms impact coastal areas, living shorelines are a state research priority to support coastal risk reduction and resilience goals. However, while the ecological benefits of living shorelines are well-documented, few studies have examined the social and institutional factors that hinder or support the design and implementation of living shorelines in Florida.Our study applies an integrated framework combining results from expert interviews with a policy analysis to evaluate decision-making contexts and considerations related to living shorelines in Florida. We present barriers and enablers of living shorelines as perceived by practitioners and marine contractors. Key barriers to adoption of living shorelines include rule or permitting-related mismatches, community-level use and access concerns, and environmental design uncertainties. Enablers include community-level education and incentives, increased demonstration projects, and criteria or policy standardization for living shorelines. We then connect these barriers and enablers to policy priority patterns drawn from coastal management plans in select Florida counties. These policy priority patterns involve defining nature-based and hard solutions, addressing public and private access concerns, and resolving restoration and conservation goals when considering living shorelines as an appropriate coastline stabilization and protection measure. By connecting on-the-ground practical experiences with insights from coastal management policies, our study provides a socio-institutional methodology and contextual baseline for the planning and implementation of living shorelines in Florida and similar coastal areas.

The use of small-arms stability measures in combat shooting assessments

The acquisition of weapons at scale requires objective measures to discriminate between products and inform decisions. Testing of weapons commonly occurs on known-distance ranges in static positions at static targets using accuracy and timing as the main variables of interest. However, testing weapons in more representative environments may better show variations in ergonomic-related factors such as centre-of-gravity (CoG) changes. This study aimed to examine the utility of weapon accelerations as a measure of stability, understand how stability changes with repeated shots and the responsiveness to changes in the CoG. Eighteen soldiers shot 60 times under four conditions: an unweighted rifle and the addition of a mass fixed at three different positions. A weapon-mounted accelerometer captured the accelerations of the weapon 200 ms before shot release. Twelve stability measures were calculated and reduced via a principal component analysis. Three of these metrics were then assessed for changes over the shots and between the four conditions. Decreased stability occurred over the 60 shots for all conditions, suggesting increasing fatigue. Stability only differed between one pair of conditions with one metric, implying that stability can be maintained with the different weapon configurations.

Towards more sustainable, nutritious, and affordable plant‐based milk alternatives: A critical review

AbstractThe consumer market has seen a surge in various types of plant‐based milk alternatives (PBMAs), driven by factors such as sustainability, ethics, and the availability of diverse options. However, the global adoption of PBMAs is still hindered by potential nutritional concerns and cost‐ineffectiveness. It is therefore paramount to understand the status and challenges of these alternatives, encompassing production, stabilization strategies, nutrition and health, digestion, and environmental impacts. This review provides a comprehensive examination of these aspects. We begin by scrutinizing the production processes and formulation strategies of PBMAs, followed by an exploration of fundamental stabilization aspects, including homogenization, emulsification, thickening, and quantitative measurements of stabilization. Additionally, we discuss their nutrition facts and potential health benefits, as well as potential differences in the digestion of nutrients from PBMAs. Importantly, their challenges and future directions are discussed individually, highlighting the need for a fundamental understanding and effective food technologies to develop sustainable, nutritious, tasty, and affordable PBMAs. For example, several critical aspects involve maximizing the use of plant materials (e.g., proteins, fibers, and bioactive compounds) and using reliable and unified life cycle analyses to guide the development. This review offers valuable insights for researchers, food technologists, and consumers seeking to navigate and develop the landscape of PBMAs effectively.

1999 – 2024, a Quarter Century of the Parr’s Electrophilicity ω Index

In 1999, Robert G. Parr introduced the electrophilicity w index as a measure of the electronic stabilization of a molecule when it acquires an additional amount of electron density. Numerous theoretical studies over the last 25 years have demonstrated the usefulness of this index in the study of polar reactions. The present MEDT study reinforces the relevance of Parr’s electrophilicity w index as a quantitative measure of the electrophilic character of species involved in a polar reaction.

A particle swarm optimization inspired global and local stability driven predictive load balancing strategy

In distributed systems and parallel computing, optimal load balancing is difficult. These abstract addresses load balancing in distributed situations, highlighting current solutions' flaws and emphasizing the need for new ones. Load balancing research includes centralized and distributed algorithms, heuristics, and predictive models. Despite various successful methods, workload adaptability, overhead reduction, and scaling to large systems remain unresolved. This study proposes a particle swarm optimization (PSO) load balancing method that considers global and local stability considerations. The proposed method uses PSO principles to balance exploration and exploitation and allocate resources among distributed nodes. Predictive components improve preventative load management by predicting workload changes. Global and local load balancing stability criteria distinguish this study. The recommended method considers global system-wide performance indicators, local node-level characteristics, and micro-level stability to maximize system efficiency. A dual-focus technique distinguishes the proposed load balancing strategy from others, solving dynamic distributed system challenges. The study examines load balancing system advances and suggests improvements and further research. More accurate prediction modeling, stability measures, and application-specific enhancements may be studied in the future. Experimental validation and real-world implementation of the recommended approach are necessary to determine its practicality and ability to handle modern distributed computing systems.

Management of Intraoperative Acetabular Fractures in Total Hip Arthroplasty: A Current Concept Review.

Intraoperative acetabular fractures (IAFs), a complication seldomly encountered in total hip arthroplasty, are typically a result of the impact of insertion of a cementless press-fit cup. Factors that contribute to the risk of these types of fractures include poor bone quality, highly sclerotic bone, and the use of a press-fit cup that is excessively large. The approach to management of these fractures is dependent on when they are identified. Immediate stabilization measures should be implemented for management of fractures detected during surgery. When fractures are detected postoperatively, the decision regarding conservative treatment is dependent on the stability of the implant and the specific fracture pattern. In the majority of cases, effective treatment of an acetabular fracture detected intraoperatively can be administered using a multi-hole revision cup along with anchoring screws in the various regions of the acetabulum. Selection of plate osteosynthesis of the posterior column is recommended when there is a large posterior wall fragment or pelvic discontinuity. In cases where anatomical dimensions allow, cup-cage reconstruction may offer a promising alternative to a combined hip procedure. The number of reports addressing the management of IAFs is limited. This review focuses on outlining the strategies that are currently available for management of this seldomly encountered complication.

Postural and spinal stability analysis for different floor sitting styles

In contrast to Western countries, traditional floor-seating cultures are prevalent in Korea, Japan, the Middle East, and Africa, where sitting on the floor in static positions such as squatting, kneeling, or sitting cross-legged is common. Most studies on sitting posture have predominantly focused on chair sitting in Western cultures, resulting in a cultural bias. This study aimed to investigate the effects of different cushion types (floor and traditional cushions of 3-cm, 5-cm, and 8-cm thickness) and seating postures (cross-legged, mother's leg, and kneeling) on measures of postural stability, trunk muscle activity, rotational spinal stability, and subjective postural stability in an Asian population. Forty right-hand and right-foot-dominant volunteers who did not experience activity-limiting back pain in the past 12 months were recruited. Multivariate analyses of variance (MANOVA) and ANOVA with a repeated-measures design were employed to assess the within-subject effects of the cushion type and seating posture. An alpha value of 0.05 was set for statistical significance. The results of this study suggest that preventing lordosis posture, seating on the floor, and maintaining a kneeling posture may reduce the loss of balance and trunk muscle fatigue. These results emphasize the need for additional ergonomic studies that focus on the seating traditions of Asian cultures.

Evaluation of Pyroxasulfone Crop Safety and Weed Control for California Tree Nut Orchards

Pyroxasulfone is a very long chain fatty acid (VLCFA) inhibitor (group 15) with potential for preemergence weed control in orchard crops and would be beneficial for reducing selection pressure for resistance to more commonly used herbicides, such as glyphosate. Pyroxasulfone is registered and widely used in corn and soybeans in the United States as a solo product and in several premix formulations. However, there is limited published information on the performance and safety of pyroxasulfone in tree nut orchard systems. To assess the potential fit for pyroxasulfone in this crop sector, a series of crop safety and weed control efficacy experiments were carried out in key California orchard crops and in fallow fields with common orchard weeds. The non-crop studies were conducted near Davis, CA, to evaluate winter annual weed control with pyroxasulfone in comparison with pendimethalin and indaziflam. In addition, an irrigation incorporation experiment was conducted in summer to evaluate the effects of incorporation timing on pyroxasulfone, pendimethalin, and indaziflam efficacy as a measure of relative stability. Orchard weed control experiments were conducted in spring in an almond orchard near Arbuckle, CA, and a walnut orchard near Davis, CA. The orchard experiments included pyroxasulfone, pendimethalin, and indaziflam in various rate combinations with glufosinate. To evaluate crop safety, 2-year experiments were conducted to evaluate repeated applications of above-label rates of pyroxasulfone at 1199 g·ha−1 and S-metolachlor at 14,010 g·ha−1 on 1- to 2-year-old almond, pistachio, and walnut trees near Davis. Pyroxasulfone performed similarly to commercial standards with up to 95% control of broadleaf and grass weeds with pyroxasulfone and indaziflam providing 96% to 100% control of annual bluegrass, and pyroxasulfone (293 g·ha−1) being the only herbicide to suppress (&gt;70%) common lambsquarters at 60 days after treatment (DAT). Other weeds controlled by pyroxasulfone include swinecress, redroot pigweed, yellow nutsedge, and Italian ryegrass. No differences were found among treatments in the incorporation timing study indicating adequate stability on the soil surface under summer conditions. Crop injury was not observed in the established orchards or the young orchard studies and there were no treatment effects on tree trunk diameter of almond, pistachio, and walnut in the 2-year crop safety experiments. These results indicate a potential for pyroxasulfone in California tree nut orchard systems that would be an additional site of action and beneficial for management of herbicide-resistant weeds in these crops.
