TO THE ISSUE OF STANDARDIZATION OF THE TECHNOLOGY OF SCENE EXAMINATION (INVESTIGATION)
Authors: Poltavskyi A.
Published: May 2019

The article is devoted to one of the most frequently faced crime investigation procedure – scene examination (investigation), during which an investigator and a specialist to recognize, record, collect, transport and store trace information before conducting expert examination. Their activity, in this case, consists of a number of main stages: the recognition of traces on the subjects, which at the time of the commission of crimes could have formed traces and which (subjects with traces) can be collected; the recognition of traces on the subjects, which cannot be collected; recording, collecting, packing of traces on the subjects and traces; transportation of collected subjects with traces and traces to the pre-trial investigation authorities, its storage until sending them to the institution of forensic examinations; samples’ obtaining for comparative examination; transportation of subjects with traces and traces and samples for expert research. These main stages constitute the technology of scene examination (investigation), which (technology), in the general context, is defined as a set of knowledge, information about the sequence of separate work operations in the production process of something.

The analysis of the integration of the concept of “technology” in forensic science and forensic expertology showed that the general understanding of the term “technology” there is no classification of technologies, their structure and content, and the order of representation at a practical level for the implementation into crime investigation.

The article illustrates some shortcomings of scene examination (investigation). The analysis of regulations that adjusting scene examination (investigation) shows that they do not have detailed instructions for the implementation of specific actions by specialists. In the opinion of the author, the solution of problematic issues should be the standardization of the institutions’ activities that provide for the conduct of scene examination (investigation) and expert research. The article briefly deals with the history of international standardization, the state of standardization in Ukraine, analyzes the provisions of the international standard ISO 21043-2: 2018 “Recognition, recording, collecting, transport and storage of items” (which have potential forensic significance).

According to the results of the research, conclusions were made on the necessity of implementation into the work of the institutions that provide scene examination (investigation) and expert research, quality management systems in accordance with the requirements of ISO/IEC 17020 ISO/IEC 17025, as well as the harmonization of the international standard ISO 21043-2: 2018 as a national regulatory document (National Standards of Ukraine (DSTU)) with the further implementation into practical activities on crime detection.

TYPES OF THE SIGHNS AND METHODS OF THEIR DIAGNOSTIC ANALYSIS IN THE LINGUISTIC RESEARCH OF ORAL SPEECH
Authors: Ovannisian А.
Published: May 2019

The article examines a set of issues related to the features of the classification of signs of oral speech for various diagnostic and evaluation criteria:

– by their stability / instability;

– by their origin (congenital / acquired);

– by their nature (dynamic / static);

– according to the form of implementation (materially expressed / hidden);

– according to their functional purpose (monofunctional / multifunctional);

– by their composition (simple / complex / complex /;

– by their classification significance (general / private);

– by frequency of implementation in speech, etc.

All listed classification groups of signs are described both in the content plan and in the functional one, that is, the features of their identification, evaluation of the factors under the influence of which they formed and the evaluation of their diagnostic and identification significance are analyzed. Such an approach to their study is due to the fact that the possibility of correlating a trait with a particular area of ​​scientific knowledge is not always obvious and unambiguous. Different properties of the human person can be realized in his speech in the form of one and the same sign. For example, a more closed version of the pronunciation of sound [a] can manifest itself as an individual feature of the articulation of a particular person, as a sign of speech in a non-native language or a dialect feature (a common sign that is studied in the framework of sociolinguistics, psycholinguistics and linguistics), as a sign of imitation which is studied in the framework of psycholinguistics, sociolinguistics, linguistics), as an accidental (unstable) feature, the manifestation of which is due to the physical state of the speaker, nicative situation (eating, jogging in the process of speaking), etc. Therefore, understanding the nature of the origin and realization of a particular sign in speech is a fundamental condition for its correct classification, on the basis of which an objective assessment of its diagnostic and identification significance is subsequently achieved in the complex of signs of a particular person’s speech and, consequently, of his forming expert conclusions.

The article also outlines the principles for the classification of signs according to their composition by dividing them into three groups: simple signs, complex and complex. Particular attention is paid to complex features (for example, signs of cross-language interference), which consist of simple signs and are established after analyzing the signs of the components. As a result, complex signs are often not fully investigated, which can lead to the bias of the expert’s conclusions.

Key words: linguistic study of oral speech, diagnostic analysis, idiolect, classification, sign, evaluation of the significance of the sign, complex of signs, persistent sign, intensity of manifestation of signs, interlingual interference, level of linguistic research.
PROBLEM ASPECTS ON DETERMINING THE INTERFERING FACTORS IN STUDIED SIGNATURES PERFORMED BY MANUSCRIPTED METHOD
Authors: Bandurko V.
Published: May 2019

The article is devoted to the consideration of problematic situations that may arise when determining interfering factors (natural, artificial) when in the investigated signature their combined effect manifests itself or the presence of the same information content under the influence of various interfering factors is found.

Considering the possibility of such complex cases arising from the ambiguity of the origin of interfering factors, with insufficient information content of the signature, an insignificant number of free samples identifying features that prevailed over others, the ability to explain the differences and the lack of full confidence in the categorical expert is a probable form of conclusion.

To sum up it can be concluded that handwriting experts obtain scientific research on the identification of interfering factors affecting the signer. The level of knowledge and experience of the expert, the perfection of research methods, etc. will play an important role.

Key words: signature, interfering factors, natural, artificial.
ON THE ISSUE OF THE FAKE IDENTIFICATION DOCUMENTS
Authors: Naumenko S.
Published: May 2019

Summarizing the foregoing, we can draw the following conclusions: documents made on a polymer basis have both certain advantages and disadvantages, most of the drawbacks are connected with the use of decentralized personalization, insufficiently effective control over consumable materials and the possibility to reuse the original form for the processing a fake document. The advantage of identification documents is the use in their production and centralized personalization of modern technological solutions, which ensures the presence of a complex of security features. Therefore, in order to ensure the proper level of examination of identification documents, experts should be provided with samples or electronic collections with a description of security features and equipped with modern equipment.

Key words: fake, identification documents, expert research.
GROUP IDENTIFICATOIN OF CARTRIDGE CASES DISCHARGED FROM HOMEMADE SUB-MACHINE GUNS
Authors: Hiverts P.
Published: May 2019

The increasing number of homemade sub-machine guns in caliber 9 mm Parabellum received for examination, as well as cartridge cases discharged from this weapon, made it necessary to single out the marks which can be used for group identification. The article gives the results of generalizing and systematization of marks observed during the examinations made in the laboratory. This work singles out the marks and traces which can be observed on the cartridge case surface and can be used for the identification of the type and model of the firearm. The construction features of homemade sub-machine guns were investigated. Among these features are the construction based on open bolt mechanical scheme, the use of static firing pin, methods of barrel assembling and fixing into the body of the weapon, which can lead to the appearance of a hole in the chamber, etc. The article also shows the influence of the tool processing on leaving special marks and traces on the breach face. These marks can also be used for the group identification.

Based on the results of the research the article distinguishes between the main signs, which can be used for group identification, the sings similar to the ones known in factory-made weapons and the signs typical of homemade firearms.

The first group consists of the marks of ejector and the extractor cutouts and the firing pin mark. For these sings the article describes special characteristics which makes it possible to distinguish them from the marks commonly observed on the factory-made examples.

To the marks typical of homemade sub-machine guns can be applied breach face marks, cartridge case deformation, caused by differences between the sizes of the chamber and the cartridge, cartridge deformation while shooting when the cartridge case is not supported by the chamber, perforation of the sidewall of the cartridge case, etc.

The article also discusses the issue of cartridge case comparison and individual identification. Great variety of the traces and marks as a result of low-quality tool processing was revealed. This can be the factor which makes comparison more difficult. However, the big number of individual marks observed on the cartridge cases makes it possible to come to well-grounded conclusion.

Key words: cartridge cases, submachine guns, type and kind of weapon, expert practice.

The popularity of asphalt mixes on a polymer-bitumen binder is caused by the desire to ensure the operational reliability of road pavements due to the axle load of vehicle and the intensity of traffic. In addition, the use of an appropriate type of binder has become an important direction in ensuring the operational reliability of asphalt concrete pavements, suitable for the specific conditions of the region, marked with PG. The provision of required set of properties of the polymer-bitumen binder largely depends on the percentage of the polymer and on the type of plasticizer used. The article presents the results of comparative tests of polymer-bitumen binders with the use of six different plasticizing agents. The dependence of changes in the indicators of modified binders and their thermal stability is investigated. Recommendations are given to maintain the required level of physical and mechanical parameters of polymer-bitumen binder.

Published: May 2019

The article presents processing module of experimental thermal characteristics of machine tools in real time using high order derivatives. It is developed in a high level programming language. This module is a part of automated system of tests and diagnostics of machines thermal state. The module is equipped with a graphical user interface; it works in real time, allows performing procedures for smoothing experimental thermal characteristics and determining their prognostic values. This allows building curves of speed, acceleration and sharpness of temperature change over the time. The developed software module implements a new algorithm based on the Horner’s method. The practice of developing algorithmic software shows that the chosen method is very convenient and effective for machine implementation, due to the absence of a division operation at each computational step. It is experimentally confirmed that the total costs of performing the calculations of high order derivatives of an arbitrary degree polynomial using the Horner’s method according to the described algorithm are acceptable for real-time calculations on a standard personal computer. Data temperature and temperature movements of the machine working bodies can be processed using the developed algorithms. In addition, this algorithm allows calculating the value of the approximating polynomial and simultaneously obtaining the values of all its derivatives at a given point. This allows to solve the problem of "shift in time by step" of the position of characteristic points.

Provider Resistance to Evidence-Based Practice in Schools: Why It Happens and How to Plan for It in Evaluations
Authors: Saavedra Lissette M. , Morgan-Lopez Antonio A. , Yaros Anna C. , Buben Alex , Trudeau James V.
Published: May 2019

Evidence-based practice is often encouraged in most service delivery settings, yet a substantial body of research indicates that service providers often show resistance or limited adherence to such practices. Resistance to the uptake of evidence-based treatments and programs is well-documented in several fields, including nursing, dentistry, counseling, and other mental health services. This research brief discusses the reasons behind provider resistance, with a contextual focus on mental health service provision in school settings. Recommendations are to attend to resistance in the preplanning proposal stage, during early implementation training stages, and in cases in which insufficient adherence or low fidelity related to resistance leads to implementation failure. Directions for future research include not only attending to resistance but also moving toward client-centered approaches grounded in the evidence base.

Published: May 2019

Purpose – the purpose of this research is to find the benchmark, triggering a significant shift of the EU transport infrastructure construction sector from usual labour to the IT-based project implementation. The work aims to find obstacles that hold off IT from booming in this sector.

Research methodology – following the literature overview, three bills of quantities of sample transport infrastructure construction projects selected as the objects for analysis and the mathematical-statistical method was applied to actually completed projects to find the benchmark for costs of respective IT development.

Findings – the findings of this work suggest a 10% benchmark of project scope, applicable for IT innovations at the expense of human labour demand.

Research limitations – EU financial support and public procurements of investment projects are mostly applicable for investment phase. This research is therefore limited to the analysis of investment activities.

Practical implications – the industry stakeholders would welcome the IT if innovations developed with the budget not exceeding the benchmark. IT researchers and developers could use the results for cost adjustments of their offered solutions to the EU transport construction companies.

Originality/Value – this work encourages discussions on initiation of the initiatives at the political level aiming to the requalification of the existing unemployed labour force in order to meet the current labour demand in the construction market as a whole.

Authors: Radavičienė Indrė , Dikčius Vytautas , Slavuta Veranika
Published: May 2019

Purpose – this paper aims to examine the effect of framing price promotion on consumers’ purchase intentions. The main purpose of this paper is to analyse the impact of percentage and monetary price discount frames, discount levels of 20%, 40%, 60% and 80% on customer behavioural intention and perception within a high-end hospitality industry context.

Research methodology – this study considers 8 manipulated sample scenarios that have been developed. In summary, the experiment consisted of 2×4 designs of the high-end hospitality industry. Two independent variables were included in the experiment: two discount formats (€-off, %-off) and four discount levels to instigate the impact it has on the behavioural intentions and perceptions.

Findings – research has proved that in the high-end hospitality industry, different price discount frames and levels have a significant impact on customer behavioural intentions and perceptions.

Research limitations – the results of this study show that the threshold for the discount rate may depend on the type of hotel. Therefore, in the future, the impact of a discount on several hotels of different levels should be assessed in one study.

Practical implications – the practical implication for service firms that want to use price discount promotions to encourage sales and increase revenue is that they should carefully consider the price range and the value or quality of image they intend to signal when using these different price discount frames and the service they are selling to determine the discount level to use.

Originality/Value – this paper is valuable to high-end service marketers that seek to use price discount promotions to encourage sales and increase revenue.

Published: May 2019

Purpose – ageing population causes a number of economic and social problems related to changes in the labour market. This study aims to evaluate the effect of the ageing population on the labour force which is the main indicator of the labour market in EU member states. Research methodology – in order to achieve the aim of the study we applied the following methods: i) trend analysis to estimate and present population and changes of labour force over period, and ii) decomposition method to examine the effects of population and labour force structure in terms of age changes on size of labour force. Findings – over the 2003–2017 period volume of the labour force has declined in Romania, Lithuania, Portugal, Latvia and Greece. This negative effect is influenced by both depopulation and structural changes in the workforce, including population ageing. Size of the labour force has increased in 23 countries, but in 11 of them, these positive changes were influenced by the rising of population activity, while depopulation it influenced negatively. Research limitations – research results support the theoretical approach that ageing population may negatively affect the labour market but do not provide ways to solve this problem and this is the implication for further research. Practical implications – the obtained results are useful for policymakers of the labour market (including pension reforms). Originality/Value – the study contributes to scientific literature by sufficient understanding of ageing population problems that occur in labour market and fills the gap in research of ageing population impact on the labour market, using data of EU member states.

Competitiveness factors in the innovative enterprises
Authors: Decyk Kamil
Published: May 2019

The research problem was to determine the relationship between having an action plan related to innovations
by innovative enterprises and the type and degree of these enterprises’ use of competitiveness factors. The objective of
the research was to identify and assess competitiveness factors in innovative enterprises taking into consideration their
strategic plans related to innovation management. For achieving this objective, the following research methods were
used: analysis of national and foreign literature resources, survey measurement (observation technique), direct and indirect interview, research tool: questionnaire. The results were analyzed with statistical methods such as arithmetic
mean, Mann-Whitney U test, Chi-square test (χ2), and measures of the association including Pearson's contingency
coefficient and Cramér’s V coefficient were applied.
The analysis of the results showed that the assessment of competitiveness factors such as innovativeness, quality, marketing and logistics activities differed with statistical significance depending on whether the firm had a long-term action
plan related to innovations. The research also showed a relationship between competing using innovativeness and having
an action plan related to innovations. However, this relationship was not statistically significant. As a result, the research
hypothesis can be neither rejected nor confirmed.
The conducted research proves that it is worth for innovative enterprises to develop long-term action plans related to

Purpose – one of the essential activity of the university is academic study process. The aim of the article to
reveal the complexity of the study process and evaluate the significance of the criteria that compose it.
Research methodology – university study process content analysis was based on the concept of Internal Study Quality
Assurance for higher education institutions formulated by the Bologna Process. The multi-criteria decision-making
method Analytical Hierarchy Process was used to achieve the aim.
Findings – the experts who participated in the research represented three universities. According to experts opinions,
we can conclude that the significance of the criteria of the study process is different among different experts.
Research limitations – selection of only one process of university performance – study process – seen as the main
limitation of performed research.
Practical implications – the proposed set of indicators can help universities to measure the quality of their study process
in order to achieve better performance. These results also could be useful for other Universities.

significant criteria that could provide Universities better understanding in which way to develop the university study process
A structured framework for sustainable supplier selection using a combined BWM-CoCoSo model
Authors: Hashemkhani Zolfani Sarfaraz , Chatterjee Prasenjit , Yazdani Morteza
Published: May 2019

Purpose – sustainability in industrial organizations is becoming one of the predominant concepts in the context of modern industrialization due to global warming, economic significance, and social awareness. These have
prompted a huge concern toward sustainable supply chain management (SSCM) to be adopted and promoted as an
innovative business model. Supplier evaluation and selection play a significant role in SSCM for taking appropriate
procurement decisions.
Research methodology – a hybrid MADM model based on Best Worst Method (BWM) and Combined Comprise Solution (CoCoSo) method.
Findings – a case study in the steel industry is presented to demonstrate the effectiveness of the proposed approach. The
results show the potentiality of the proposed model in resolving complex sustainability issues in the SCM environment.
Research limitations – other weighting techniques like the analytic network process (ANP) and decision making trial
and evaluation laboratory (DEMATEL) approaches can also be combined and performances can be compared.
Practical implications – the proposed model can be used by the organizations to select the most appropriate suppliers
who contribute to the movement of the SC towards sustainability.
Originality/Value – a multi-criteria evaluation model has been proposed for solving a sustainable supplier selection
problem while considering economic, environmental and social criteria simultaneously by integrating BWM-COCOSO
