Validating crime prevention through environmental design construct through checklist using structural equation modelling

To date, there has been limited empirical exploration of Crime Prevention Through Environmental Design (CPTED) measures to appraise their efficiency. The intention of the present study is to validate CPTED dimensions and its respective indicators developed to measure the CPTED construct. This construct is measured using four main dimensions, namely natural surveillance, access control, territoriality and exterior maintenance. The aim of this study is to identify factors that contribute in measuring the CPTED construct. The scale was administered by using on-site observation of a sample of 164 respondents in a typical residential area in Penang, Malaysia. The validation is carried out by employing the Confirmatory Factor Analysis using AMOS. The analysis was conducted by testing the higher order dimensionality of the CFA driven first-order solution by examining a second-order model. The final CPTED construct consists of four main dimensions with its respective indicators.     

Internal validation of reduced PCR reaction volume of the Qiagen Investigator® Argus X-12 QS Kit from blood samples on FTA cards

The onus of proof in criminal cases is beyond any reasonable doubt, and the issue on the lack of complete internal validation data can be manipulated when it comes to justifying the validity and reliability of the X-chromosomal short tandem repeats analysis for court representation. Therefore, this research evaluated the efficiency of the optimized 60% reduced volumes for polymerase chain reaction (PCR) amplification using the Qiagen Investigator® Argus X-12 QS Kit, as well as the capillary electrophoresis (CE) sample preparation for blood samples on Flinder's Technology Associates (FTA) cards. Good-quality DNA profile (3000–12,000 RFU) from the purified blood sample on FTA card (1.2 mm) were obtained using the optimized PCR (10.0 μL of PCR reaction volume and 21 cycles) and CE (9.0 μL Hi-Di™ Formamide and 0.3 μL DNA Size Standard 550 [BTO] and 27 s injection time) conditions. The analytical and stochastic thresholds were 100 and 200 RFU, respectively. Hence, the internal validation data supported the use of the optimized 60% reduced PCR amplification reaction volume of the Qiagen Investigator® Argus X-12 QS Kit as well as the CE sample preparation for producing reliable DNA profiles that comply with the quality assurance standards for forensic DNA testing laboratories, while optimizing the analytical cost.     

Openness, Uncertainty, and Social Spending: Implications for the Globalization— Welfare State Debate

We extend the literature on openness and spending in developing countries arguing that the effect of increasing openness depends on both regime type and the level of openness. Democracies respond to increases in openness by increasing spending while dictatorships respond by decreasing spending. However, the degree to which countries pursue the strategy of choice depends on the level of openness. In autarkic countries, an increase in import competition has more severe consequences for perceptions of job insecurity and dislocation. In response, government management of openness will be more vigorous under these conditions regardless of whether the leader increases or decreases spending. Economic selection mechanisms at work will produce an outcome wherein, at higher levels of openness, further import liberalization has smaller effects on perceptions of job insecurity and dislocation. Hence, both the demand and the supply of government management of openness will be lower.     

Renewal Acute Toxicity of Broad-Spectrum Herbicide,Paraquat Dichloride in Channa punctatus (Bloch)

Abstract

Paraquat dichloride (PD) is a major contaminant in aquatic environment and is a cause of concern to different organisms, especially to fishes, as it causes different changes in behavioral and morphological to aquatic creatures. Hence, the objectives of the study are to examine the acute toxicity, behavioral and morphological alterations in air-breathing teleost fish, Channa punctatus (CP) (Bloch). Renewal acute toxicity was performed to calculate the lethal concentration (LC₅₀) by Finney’s probit analysis to CP by exposure to wide range of PD concentrations (30, 60, 90, 120, 150?mg/L) for 24, 48, 72 and 96?h. The LC₅₀ values determined are 93.36, 82.22, 67.93 and 65.87?mg/L for 24, 48, 72 and 96?h, respectively. Maximum allowable toxicant concentrations (MATC) defined by LC₅₀ value is found to be 0.6587?mg/L. The upper and lower 95 percent confidence limit (Fiducial limit) are in narrow range for 24, 48, 72 and 96?h, respectively, and thus results of the experiments are considered good. Fiducial limit calculated helps us to state that the LC50 falls within the specified limit and helps in constructing of toxicity curve. LC50 value gradually decreases with increase in time. Mortality rate was dose-time dependent and increased with increase in concentration. The behavioral changes provide biologically relevant endpoints in evaluating toxicity testing. Deviation from baseline behavior was noticed. Morphological deformities were also seen. The present study provides a clear indication of the toxicity of PD, and is highly toxic even at low level. Hence, it is recommended that appropriate eco-toxicological risk assessment should be made and indiscriminate use of PD by farmers should be discouraged particularly in areas close to aquatic environment.     

Evaluation of Skin Surface as an Alternative Source of Reference DNA Samples: A Pilot Study

An acceptable area for collecting DNA reference sample is a part of the forensic DNA analysis development. The aim of this study was to evaluate skin surface cells (SSC) as an alternate source of reference DNA sample. From each volunteer (n = 10), six samples from skin surface areas (forearm and fingertips) and two traditional samples (blood and buccal cells) were collected. Genomic DNA was extracted and quantified then genotyped using standard techniques. The highest DNA concentration of SSC samples was collected using the tape/forearm method of collection (2.1 ng/μL). Cotton swabs moistened with ethanol yielded higher quantities of DNA than swabs moistened with salicylic acid, and it gave the highest percentage of full STR profiles (97%). This study supports the use of SSC as a noninvasive sampling technique and as a extremely useful source of DNA reference samples among certain cultures where the use of buccal swabs can be considered socially unacceptable.     

Oil price changes and stock market returns: cointegration evidence from emerging market

The aim of this paper is to examine whether changes in nominal oil prices (Brent and West Texas Intermediate (WTI)) affect the stock market returns in the context of an emerging market framework. The Autoregressive Distributed Lag bounds testing approach of cointegration is used to test for the long run relation between the two variables, where the daily stock market index return is calculated using the first difference in the natural logarithms of stock market index. Further, we test for the stability of the cointegration relationship by examining the sensitivity analysis where diagnostic tests for serial correlation (namely the Breusch–Godfrey serial correlations LM test) and cumulative sum of recursive residuals (CUSUM) are employed. Using daily data from January 3, 2000 to December 9, 2015, the findings suggest that there is long run integration between oil prices and stock returns series in which the daily oil price shocks have a negative impact on stock returns. The highly significant error correction coefficient indicates high rate of convergence to equilibrium. In addition, the Toda and Yamamoto (J Econom 66(2):225–250, 1995) Granger non‐causality test indicates significant bidirectional causality between stock market returns and Brent nominal oil price, meanwhile there is unidirectional causality running from WTI oil price to stock market returns. These findings are, up to some extent, meaningful for investors, portfolio managers and policy makers.
