Draft paper for Criminal Investigation Workshop

“Society cannot afford investigative interviewing to be poor. This affects people’s perceptions of the criminal justice system. The guilty get away, the innocent are convicted, justice for children and vulnerable adults is inadequate. Poor interviewing is of no value to anyone; it is a waste of time, resources and money. No one wins. People will not come forward if they have no confidence in the quality of investigators’ interviewing techniques”. Milne and Bull (1999, pg 191):
Seasonal variation in the song structure of tui (Prosthemadera novaeseelandiae)

Birdsong has evolved to help individual birds attract mates and defend territories. The breeding season is a critical period in the life history of many songbird species and previous studies indicate that bird vocal behaviour changes at the onset of breeding season. In this study, we compared the complex songs of a seasonal-breeding New Zealand honeyeater, the tui (Prosthemadera novaeseelandiae), between breeding and non-breeding seasons. We found that males' songs in the breeding season contained significantly greater proportions of trill components compared with songs in the non-breeding season. Trill rate and consistency may be related to individual quality and therefore might signal to rivals and potential mates the quality of the singer. This is the first study to show the differences in singing behaviour of tui between seasons and provides a basis for future studies to explore the drivers of this seasonal variation in song behaviour.
Governmental partnerships for language learning: A commercial language platform for young workers in Colombia

In June 2015, the Colombian government via the Labor Ministry announced a project for young workers called 40.000 Primeros Empleos. In the framework of this project, the Ministry of Labor signed an alliance with the language platform Duolingo as a strategy to provide participants with English learning opportunities and a free language certificate. With the help of a monitoring and evaluation perspective, this study describes Colombian English language learning policies and their relationship with the labour market. The discussion presented here intends to maximize the outcomes of these kinds of agreements and to provide insights for researchers and national stakeholders willing to carry out similar projects in their countries. Certification is also thoroughly analyzed as a means of estimating the possible impact of this partnership.
Virtual Secure Coprocessing on General-purpose Processors

Cryptographic processing is a critical component of secure Internet-connected computing systems. Furthermore, the methods employed to manage, store, and exercise a user’s cryptographic keys greatly affect the security offered by cryptographic operations. Software-only user key management schemes contain numerous security weaknesses. Thus, many systems protect keys with distributed protocols or supplementary hardware devices, which include smart cards and cryptographic coprocessors. However, these key protection mechanisms suffer from various combinations of user inconvenience, inflexibility, performance penalties, and high cost. In this paper, we propose architectural features for general-purpose processors that facilitate virtual secure coprocessing. We describe modest hardware modifications and a trusted software library that allow generalpurpose processors to perform flexible, high-performance, and protected cryptographic computation. The hardware additions include a small key store in the processor, encryption engines at the cache-memory interface, a few new instructions, and minor hardware platform modifications. With these enhancements, users can store, transport, and employ their secret keys to safely complete cryptographic operations in the presence of insecure software. In addition, we enable users to securely access their keys on any Internet-connected computing device (that includes our modifications) without requiring auxiliary hardware such as smart cards.
Land application of spent gypsum from ditch filters: phosphorus source or sink?

Agricultural drainage ditches can provide a direct connection between fields and surface waters, and some have been shown to deliver high loads of phosphorus (P) to sensitive water bodies. A potential way to reduce nutrient loads in drainage ditches is to install filter structures containing P sorbing materials (PSMs) such as gypsum to remove P from ditch flow. The objective of this study was to determine the effect of land-application of gypsum removed from such filters on soil P forms and concentrations. Gypsum was saturated at two levels on a mass basis of P and applied to two soils of contrasting texture, a silt loam and a sandy loam and applied at both a high and low rate. The treated soils were incubated in the laboratory at 25˚C, and samples were collected at 1, 7 and 119 days after initiation. Soil type, time after application, gypsum rate, and P saturation level all had a significant impact on soil P forms and concentrations. However, it appears that land application of spent filter gypsum at realistic rates would have little effect on soluble P concentrations in amended soils.
The Long run Relationship between Savings and Investment in Ethiopia: a Cointegration and ECM Approach

The long run relationship between saving and investment has been a serious debate in the empirical literature following the pioneering work of Feldstein and Horioka (1980). Most of these works are cross country studies and do not use long period data. The difficulty with such studies is the homogeneity assumption across the countries. Therefore country specific studies are needed to throw more light on the issue. For Ethiopia, such long period studies are either scant or do not exist. This paper tries to fill this gap and attempts to study the causal link between savings and investment in Ethiopia using cointegration method. The evidence suggests that there is no causation between savings and investment in either direction in Ethiopia. Based on these results some policy measures are recommended. Key words: Saving, Investment, Cointegration, ECM, causality, Capital mobility and Current account balance.
Potential of carapeba (Eugerres brasilianus) for aquaculture production

Eugerres brasilianus is an appreciated commercial species in the market of the northeastern region of Brazil. The purpose of this study was to analyze and determine the diet, reproductive period, and management of carapeba in recirculating aquaculture systems. The fishes were caught with a gillnet at two different places near the Sao Francisco River mouth. The stomach content was analyzed according to the frequency of occurrence method, using the index of relative importance, assessing the degsubjectedree of stomach repletion. The reproductive period was established by determining the gonadosomatic index and gonad maturation stages. The behavior and management of the fish were observed in captivity when subjected to artificial diets in cultivation tanks. The striped carapeba is best feed at dusk, mainly Crustacea Amphipoda, Insecta Chironomidae and Crustacea Tanaidacea. The species has parceled spawning, which occurs from February to March and from July to September. There are morphological differences between males and females, especially in the urogenital papilla, size and color. In captivity, the best fish density was between 7 and 8 fish m /-3 , showing a good rates of centesimal composition, adapting well to the supplied diet.
Pomen ultrazvočne preiskave pri prepoznavanju poškodbe osrednjega živčevja pri nedonošenčkih

Cranial ultrasonography (US) is a reliable tool to detect the most frequently occurring congenital and acquired brain abnormalities in preterm neonates. Appropriate equipment, including a dedicated ultrasound machine and appropriately sized transducers with special settings for cranial US of the newborn brain, and ample experience of the ultrasonographist are required to obtain optimal image quality. When, in addition, supplemental acoustic windows are used whenever indicated, and cranial US imaging is performed from admission throughout the neonatal period, the majority of the lesions will be diagnosed, and information on timing and evolution of brain injury as well as on ongoing brain maturation will be obtained. For exact determination of site and extent of lesions, for detection of lesions that (largely or partially) remain beyond the scope of cranial US and for depiction of myelination, a single, well-timed MRI examination is invaluable in many high-risk neonates. However, as cranial US allows serial bedside imaging it should be used as the primary brain imaging modality in high-risk neonates. Citirajte kot/Cite as: Soltirovska Šalamon a, Paro Panjan D.

Appraisal of Metal Contamination in Soil around Industrial Areas of Chennai , Tamil Nadu , India

Copyright © 2016 Frontiers of Current Trends in Engineering and Technology, ACET 42 Abstract: The concentration of metals (Al, Fe, Mn, Ti, Cr, Co, Ni, Cu, Zn and Pb) was studied in urban topsoil to identify the metal contamination due to modern urbanization and industrial developments. The soil samples were collected from the top portion of the soil layer (0-25 cm). The accumulation of elements in the soil was analyzed using X-ray fluorescence spectrometer. Metal contamination was calculated using Index formulas such as enrichment factor (EF), Geo accumulation index (Igeo), contamination factor (CF) and pollution load index (PLI). The trace elements are derived from anthropogenic process. Maximum concentrations of Pb, Zn and Cu was noticed near by the road side soils and are specifically derived from the high road traffic volume and leaded fuel combustion in the urban environment. The other enriched metals (Cr and Mn) were derived from industrial wastes like chrome electroplating industries. The correlation results suggest that the strong correlation between Cr, Cu and Zn indicates their common origin, especially from urban development, such as electro chrome plating industries, sewage sludge and urban runoff.
Hereditary Nephrogenic Diabetes Insipidus: Molecular Basis of the Defect and Potential Novel Strategies for Treatment

The antidiuretic hormone vasopressin regulates water reabsorption in the nephron by inducing apical plasma membrane exocytosis of the water channel aquaporin 2 in the kidney collecting duct principal cells. Disruption of this physiological mechanism by genetic alteration of either the vasopressin type 2 receptor gene or the aquaporin 2 gene, results in a rare genetic disorder known as nephrogenic diabetes insipidus, which main hallmark are polyuria and polydipsia. Over the last decades, analysis of patients affected by this disease helped genetists, clinicians, cell and molecular biologists and pharmacologists to better understand the physiology of water reabsorption in the kidney, the molecular basis of the disease and to propose protocols for rapid diagnosis and pharmacological handling of the disease. Much still remains to be done in terms of targeted therapy to make sure that these patients benefit from an improved quality of life. In this article we provide an overview on the most recent strategies under investigation for rescuing the mutated gene products activity or for bypassing defective vasopressin receptor signaling.
Micromachining of Materials using Femtosecond Laser Pulses - A Parametric Study

In the presented research, I have undertaken the problem of femtosecond laser interactions with matter, under various laser pulse parameters and considering a wide group of materials, i.e. metals, plastics, graphene, silicon. There is a considerable interest in the precise material micro and nanomachining with ultrashort laser pulses. It is well established, that the quality of ablation process with femtosecond laser is much better than when using long pulse lasers. The use of femtosecond laser pulses creates an attractive opportunity for high quality micromachining of many groups of materials and opens an interesting field in fundamental research. The objective of the fundamental research proposed within this research is a complex study of the physical phenomena occurring during shortpulsed (femtosecond) laser interactions with matter. Although the research topic itself is very popular in the scientific community, it is relatively little elucidated. A better examination of the effects of electromagnetic irradiation on the materials in the femtosecond regime will provide a better understanding of the subject. The experimental results obtained from this project and theoretical considerations will provide a verification of the existing theories on laser-matter interactions. Additionally, the experimental investigations will be carried out on novel materials, i.e. graphene. I have specifically taken under investigation the laser ablation phenomena, which occurs during a highly energetic laser irradiation of the material and results in detachment of microparticles from the material. The physics of the ablation process in an ultrashort laser pulses regime differs from the ablation caused by the long (nanosecond and picoseconds) laser pulses. The nature of the process is more complex with the short pulses and the complete, research based understanding of the phenomena is not available yet. 2 STATE OF THE ART
The determinants of Aboriginal employment income

According to the 1986 Census, the average Aboriginal male in full-time employment had an income which was 71 per cent of that of the average non-Aboriginal male. The gap between the incomes of the average Aboriginal and non-Aboriginal female was less by 11 percentage points. This study uses Ordinary Least Square (OLS) regression techniques to decompose this gap into that part which can be attributed to differences between Aborigines and non-Aborigines in certain measured characteristics, for example education and labour market experience, and that part which remains unexplained by these measured differences. Differences between groups in the monetary rewards received for a given set of labour market endowments may arise because of discrimination between groups or because of differences in their labour supply behaviour. The results of this study show that most of the difference in income between Aboriginal and non-Aboriginal men can be accounted for by differences in their labour market endowments but there remains some part which is attributed to different rewards for these endowments. Endowment differences were less important in accounting for differences in the income of Aboriginal and non-Aboriginal women. The paper concludes with some discussion of the implications for policy.
Data Mining the Effects of Testing Conditions on Brain Biomechanical Properties

Traumatic brain injury is highly prevalent in the United States. However, despite its frequency and significance there is little understanding of how the brain responds during injurious loading. A confounding problem is that because testing conditions vary between assessment methods, brain biomechanics cannot be fully understood. Data mining techniques, which are commonly used to determine patterns in large data sets, were applied to illicit how changes in testing conditions affect the mechanical response of the brain to high strain rate testing. High strain rate data was collected from published literature and Fuzzy C-means clustering applied to show that the data cluster based on strain rate, confirming that the brain is indeed strain rate-dependent. Self-organizing maps were used to conduct a sensitivity analysis to provide the following ranking of parameters by significance: (1) Age, (2) Strain rate, (3) Matter, (4) Testing temperature, (5) Storage temperature, (6) Diameter, (7) Thickness, and (8) Postmortem preservation time.
Linking business process and software system

Enterprise necessitates to follow the rapid evolution of its business processes and rapidly adapt the existing software systems to its arising needs. A preliminary requirement is that the software subsystems are available and interoperable. A widely diffused solution is moving the adopted software solutions toward an evolving architecture, such as the one based on services. The objective of the research presented in this paper is to support the reuse of the existing software systems in a Service Oriented Architecture. The proposed solution is based on the idea that a Service Oriented Architecture can be obtained from a wide range of existing pieces of software. Such code components can be extracted from the existing software systems by identifying those ones supporting the business activities. Then, the paper proposes an approach for identifying the parts of software candidate to support a business process activity and it is based on the recovering of the links existing between the model of a business process and the supporting software systems.
On the determination of internal optical mode loss of semiconductor lasers

Use is made of a numerical simulation of the light—current characteristic to examine the errors which may arise in the determination of the optical mode loss (αi) from the cavity length dependence of the external differential efficiency (ηextd). In particular, we focus on the effects of incomplete Fermi level pinning and carrier leakage, and show that αi can only be determined correctly if ηextd is determined under conditions where it is invariant both with current level and temperature.
A search for non-pulsating, chemically normal stars in the δ Scuti instability strip using Kepler data

We identify stars in the δ Sct instability strip that do not pulsate in p modes at the 50-μmag limit, using Kepler data. Spectral classification and abundance analyses from high-resolution spectroscopy allow us to identify chemically peculiar stars, in which the absence of pulsations is not surprising. The remaining stars are chemically normal, yet they are not δ Sct stars. Their lack of observed p modes cannot be explained through any known mechanism. However, they are mostly distributed around the edges of the δ Sct instability strip, which allows for the possibility that they actually lie outside the strip once the uncertainties are taken into account.We investigated the possibility that the non-pulsators inside the instability strip could be unresolved binary systems, having components that both lie outside the instability strip. If misinterpreted as single stars, we found that such binaries could generate temperature discrepancies of ∼300 K – larger than the spectroscopic uncertainties, and fully consistent with the observations. After these considerations, there remains one chemically normal nonpulsator that lies in the middle of the instability strip. This star is a challenge to pulsation theory. However, its existence as the only known star of its kind indicates that such stars are rare. We conclude that the δ Sct instability strip is pure, unless pulsation is shut down by diffusion or another mechanism, which could be interaction with a binary companion.
Automatic Image Segmentation Using Graph Cut

Image segmentation is the process of partitioning an image into multiple segments, so as to change the representation of an image into something that is more meaningful and easier to analyze. Several generalpurpose algorithms and techniques have been developed for image segmentation. Image segmentation refers to partition of an image into different regions that are homogenous or similar and inhomogeneous in some characteristics as the new graph cut approach is an emerging technique for image segmentation, as it can minimize an energy function composed of data term estimated in feature space and smoothness term estimated in an image domain. Previous approaches using graph cuts have shown good performance for image segmentation, they manually obtained prior information to estimate the data term, thus automatic image segmentation is one of issues in application using the graph cuts method. As it requires low computational complexity and is therefore very feasible for real-time image segmentation processing. In the experiments, we investigated problems of previous methods such as mean shift segmentation, watershed technique and automatic graph cut based image segmentation As a result, the graph cut method showed better performance than previous methods.
On Optimising Risk Exposures with Trend-Following Strategies in Currency Overlay Portfolios

This paper proposed an optimisation mechanism in the currency overlay portfolios construction process, an area that has not been explored in the literature that tend to focus on pre-determined fixed weights, such as the trading volume of currencies from the survey of the Bank for International Settlement, to construct overlay portfolios and may not always be optimal. This paper optimises the portfolio using the Cholesky Decomposition-based multivariate TVC (Time varying correlation)-GARCH and CC (Constant correlation) GARCH models as allocation schemes, with underlying currencies’ returns originated from a moving average-based trend following single FX strategy in a certain hedging criterion. This paper includes a FX strategy based on the equally weighted (average) of the three different single moving average days to determine hedging needs underlying the hedging criterion. The paper uses the returns of the strategies of EW (equally weighted)-TFX and TFX to construct the optimal currencies overlay portfolios. The findings reveal the EW-TFX portfolios with the TVC-GARCH scheme have the best risk-adjusted portfolio returns. There are some evidences on the significant differences of the portfolios' returns of the EW-TFX overlay portfolios with other currencies portfolios, hence supporting the outperformance. The findings also support existing evidence in the literature.
Spatially Resolved Potential Distribution in Carbon Nanotube Cross‐Junction Devices

Crossed-nanotube junctions, the basic constituents of carbon nanotube networks, are investigated by scanning photocurrent microscopy. The location of the predominant electrostatic potential drop, at the electrical contacts or at the junction, is found to be highly dependent on the transport regime. Also, whereas Schottky barriers are formed at M-S (metal-semiconductor) nanotube crossings, isotype heterojunctions are formed at S-S ones (figure).
