Published: April 2021

Objectives: we investigated on the degree of homogeneity in the employment of some working tools among primary care paediatricians working in the province of Bergamo. Methods: through the compilation of an online questionnaire, we retrospectively evaluated data recorded from February 24 to May 3 2019, by 85 paediatricians. Results: the data analysis showed a larger employment of point of care testing for paediatricians relying on nurses activity (p=0.03), and a lower number of outpatient visits for paediatricians without office staff (p=0.06). A rough doubling in heterogeneity was assessed in the employment of point of care testing when compared to the other working tools (coefficient of variation 0.66 vs. 0.27-0.37). Conclusions: these data address to the worthiness of shared procedures referring to the employment of working tools in paediatric primary care.
Leila, de Tino Freitas e Thais Beltrame
Authors: Grazioli Fabiano Tadeu
Published: April 2021

Os temas polêmicos, como o abuso sexual, quando abordados pela literatura infantil, ganham uma dimensão que só a arte pode fomentar junto aos pequenos leitores: permitem-se observar através de uma lupa, de um microscópio e, assim, ganham a visibilidade que merecem (ou necessitam) na sociedade. É o caso da obra Leila, livro ilustrado, com textos de Tino Freitas e ilustrações de Thais Beltrame, que despontou no sistema literário infantil no final do primeiro semestre de 2019. O trabalho apresenta, inicialmente, algumas reflexões sobre a obra em questão, a partir de seu enredo, conjugando o que informa ao leitor as narrativas verbal e visual, e dialogando, quando possível, com alguns pressupostos teóricos sobre o livro ilustrado, a partir do que considera Hunt (2010). Na seção seguinte, são realizadas aproximações entre a obra em análise e alguns pressupostos teóricos da literatura para a infância, momento em que são aproveitados estudos de Aguiar (2001), Bajard (2007), Colomer (2003, 2007), Gregorin Filho (2009), Souza (2014, 2016), Petit (2009), Hunt (2010), Reyes (2010), Zilberman (2003), entre outros. Tais estudos, mesmo não abordando o tema diretamente, deixam a margem necessária para que a literatura pensada para a criança inclua, no bojo de suas discussões, a temática do abuso sexual, à medida que eles depõem a favor da construção de um artefato artístico capaz de levar o leitor ao conhecimento de si mesmo e do Outro.
Placenta, verbo presente

Published: April 2021

O artigo discute o tempo linguístico em Água Viva, de Clarice Lispector, à luz da semiótica europeia. Tempo esse, o lispectoriano, que pode ser quanto dura um pensamento, como a própria autora escreveu. A narrativa interessa-se por tudo que é, pelo ser daquilo que ela descreve como it, que não é a coisa ontológica. É, por assim dizê-lo, o Deus, o mistério, o primeiro. A ela, parece-nos, importam as relações, um projeto geral, abstrato e sensivelmente poético que garante à língua a possibilidade de ultrapassagem semântica de quaisquer limites, mostrando a força das construções sintagmáticas no percurso da significação.

Upper Extremity Deep Vein Thrombosis After Botulinum Toxin Injection: A Case Report
Authors: Lim Nana , Lee Geun Su , Won Ki Hong , Kang Jin Sun , Lee Sung Hoon , Kang Eun Young , Lee Hyun Kyung , Cho Youn Kyung
Published: April 2021

Botulinum toxin (BoNT) injection is widely used to improve spasticity. However, after the treatment, the patient may experience pain, inflammation, swelling and redness at the injection site. In this case, we addressed deep vein thrombosis (DVT) after BoNT treatment of the upper limb. A male aged 37 years had spasticity and dystonia in his left upper extremity. BoNT-A 100 U was injected into the left biceps brachii and an equal amount into the brachialis to relieve spasticity. After three days, he developed redness and painful swelling in the left upper arm and the next day, through the upper extremity computed tomography venography, DVT was identified in the left cephalic vein. The thrombus resolved after the anticoagulation therapy with rivaroxaban (Xarelto). We hypothesized the role of mainly three mechanisms in the development of DVT in this case: repetitive strenuous activity, relative stasis due to reduced muscle tone, and possible direct mechanical damage to the vessel wall.

Adolescents in communicating about their sexual and reproductive health (SRH) issues are faced with the obstacles created by expected social norms and taboos related to sexuality and gender. This study aims to determine the relationship between adolescent-parent communication and its relationship with safe sex behaviour among adolescents.

The study was a descriptive cross-sectional. Data was collected from 400 adolescents in Ife-East local government using a pre-tested semi-structured questionnaire. We used a multistage sampling technique to select the required study subjects. We carried out simple frequencies and chi-square.

 Fifty –five percent (55.3%) of the respondents were females, while 44.8% are males. The mean age (±SD) of the participants was 15.50 ±1.55years. Of the respondents, only 37% had good knowledge of sexual and reproductive health issues, while 63% had poor knowledge of sexual and reproductive health issues. The predictors of adolescent parent communication among respondents are private schools (OR=2.546, P = 0.005, CI=1.327-4.885), Female sex (OR=12.128, P<0.001, CI=11.590 – 25.534),   family size (OR=14.772, P= 0.003, CI=13.037 –20.015) and good knowledge of sexual and reproductive health issues (OR=19.521, P= 0.007, CI=19.521 –29.078).  There is a statistically significant relationship between adolescent parent communication and safe sexual behaviour (X²=152.998, P <0.001, df = 1).

The findings of our study revealed that adolescents were not communicating much with parents about sexual and reproductive health issues; and that there is an association between adolescent parent communication and safe sexual behaviour.

Authors: Kombusadee Tivapron , Kurukodt Jurairat
Published: April 2021

It is widely known that systematically developed training manuals can be used to improve knowledge and practical skills and promote positive attitude of trainees. This research thus aimed to develop a training manual to help reduce the use of pesticides by para rubber farmers in Nonkheng Sub-district, So Phisai District, Bueng Khan Province, Thailand. The research was divided in to 3 stages. The first stage investigated the scenarios in which pesticides were used of the para rubber famers while the second stage dealt with the development of a training manual for promoting the reduction of the use of pesticides and hazardous chemicals by the farmers. The final stage was the evaluation for the efficiency of the developed training manual by applying it with 48 volunteered para rubber famers for 2 days. The findings revealed that the training manual had an efficiency of index at 80.38/80.89. After training with the manual, the farmers’ levels of knowledge increased tal 67.40%, while the overall post-test scores on knowledge, attitude, and practice skills in reducing the use of pesticides were found to be significantly higher (p < 0.05) than those of the pre-test. It can be concluded that the developed training manual can be effectively used to improve the knowledge, attitude, and practical skills of the trainees.
Text-Based Video: The Effectiveness of Learning Math in Higher Education Through Videos and Texts
Authors: Ghilay Yaron
Published: April 2021

The Text-Based Video (TBV) model is a particular case of the more general Video-Based Learning (VBL) model in which an instructor’s curriculum is fully covered by high-quality videos and texts. The aim of this study is to test the effectiveness of the TBV model by examining and comparing its two main components: Videos and texts.

The model is based on the creation of high-quality texts which form the basis for high-quality video clips. It is designed to improve learning in quantitative courses in higher education.

The research was based on a sample of students  who enrolled in the course Mathematics for Business Administration at the Neri Bloomfield School of Design and Education, Haifa, Israel that was based on the TBV model. The course was given during the five academic years 2016-2021 using different teaching formats: face-to-face learning, distance learning and blended learning. Learners were asked to answer an online questionnaire that assessed the characteristics and advantages/disadvantages of TBV.

The findings show that although students preferred watching videos based on texts over reading those texts alone, students opined that the combination of video and text was by far the most effective instructional method. All results were identical regardless of whether face-to-face, distance or blended learning was used.

A Large Scale, Knowledge Intensive Domain Development Methodology
Authors: Bagchi Mayukh
Published: April 2021

Since time immemorial, organization and visualization has emerged as the pre-eminent natural combination through which abstract concepts in a domain can be understood, imbibed and communicated. In the present era of big data and information explosion, domains are becoming increasingly intricate and facetized, often leaving traditional approaches of know­ledge organization functionally inefficient in dynamically depicting intellectual landscapes. The paper attempts to present, ab initio, a step-by-step conceptual domain development methodology using know­ledge graphs, rooted in the rudiments of interdisciplinary know­ledge organization and know­ledge cartography. It briefly highlights the implementation of the proposed methodology on business domain data, and considers its research ramifications, originality and limitations from multiple perspectives. The paper concludes by summarizing observations on the entire work and particularizing future lines of research.
Die US-Geheimdienste im Zeitalter der Weltkriege
Authors: Sassmann Bernhard
Published: April 2021

With the US’ rise to world power, Americans started to discuss their national intelligence services on a broad scale. This book analyses how the US got from A (‘spying is un-American’) to B (‘spying is essential for survival’). Focusing on the era of the World Wars and the immediate aftermath of World War II, it also reveals the strategies with which intelligence veterans sought to persuade their fellow Americans of the necessity of peacetime intelligence. With respect to American public debate, the first half of the 20th century thus marks the beginning of a paradox that is emblematic of American intelligence culture until this day: America’s most secret organisations are, at the same time, among its most publicised.

Authors: Alamoudi Abdullah , Abdallah Yousif
Published: April 2021

Cross-sectional imaging approaches play a key role in assessing bleeding brain injuries. Doctors commonly determine bleeding size and severity in CT and MRI. Separating and identifying artifacts is extremely important in processing medical images. Image and signal processing are used to classify tissues within images closely linked to edges. In CT images, a subjective process takes a stroke ‘s manual contour with less precision. This chapter presents the application of both image and signal processing techniques in the characterization of Brain Stroke field. This chapter also summarizes how to characterize the brain stroke using different image processing algorithms such as ROI based segmentation and watershed methods.
Effect of Transition Metal on Structural and Dielectric Properties of Mg0.5Tm0.5Fe2O4 (Tm = Zn and Cu) System
Authors: Saxena Pallavi , Yadav Anand
Published: April 2021

This study explored the structural and dielectric features of Mg0.5Tm0.5Fe2O4 (Tm = Zn and Cu) that were synthesized by the Solid-state reaction (SSR) method. The X-ray powder diffraction (XRD) analysis reveals that the prepared samples are single-phase cubic structure without any impurity. Rietveld-refined X-ray diffraction results reveal the formation of cubic structure and all the peaks of Mg0.5Zn0.5Fe2O4 and Mg0.5Cu0.5Fe2O4 are perfectly indexed in the cubic (Fd-3 m) structure. Dielectric constant and dielectric loss variation with frequency were also explored. Both decrease when the relevant alternating field is increasing and become constant at high frequencies which reflects the important role of interfacial polarization. Furthermore, the Mg0.5Cu0.5Fe2O4 having the smallest crystallite size (~ 44.73 nm) has a high dielectric constant (~ 4.41 × 104) value as compare to Mg0.5Zn0.5Fe2O4.
The Role of Introns for the Development of Inflammation-Mediated Cancer Cell
Authors: Rokeya Begum , Asrafuzzaman Mohammad , Tabassum Rashid Maliha , Nawar Shaeri
Published: April 2021

Cancer and inflammation are connected by intrinsic pathways and extrinsic pathway where the intrinsic pathway is activated by genetic events including mutation, chromosomal rearrangement or amplification, and the inactivation of tumor-suppressor genes, as well as the extrinsic pathway, is the inflammatory or infectious conditions that increase the cancer risk. On the other hand, introns are non-coding elements of the genome and play a functional role to generate more gene products through splicing out, transcription, polyadenylation, mRNA export, and translation. Moreover, introns also may act as a primary element of some of the most highly expressed genes in the genome. Intron may contain their regulatory function as CRISPR system which is activated after the demand of specific gene for specific protein formation where those are required for gene expression, they go for transcription and rest of them form splicing. This chapter will focus on the plausible role of introns to influence the genetic events of inflammation-mediated cancer cell development.

Published: April 2021

Chirality is one of the basic factors that influence a wide range of activities from chemical synthesis to tissue construction in life phenomena. Recently, researchers have attempted to use chirality as an optical signal. In animals, it is used to transmit information to insects and crustaceans, and it has also been confirmed that it promotes growth in plants. This chapter presents a new organic system that produces a chiral optical signal, that is, circularly polarized luminescence (CPL), which has been attracting attention in recent years. In particular, the chapter is focused on the generating CPL through chirality induction with the chiral self-assembling phenomenon and explaining its application as an optical film.

Authors: Khojastehfard Zahra , Salarfard Mahla , Hamedi Shokouh Sadat , Feyzabadi Zohre , Golmakani Nahid
Published: April 2021

Background: Postpartum hemorrhage (PPH) is a leading cause of mortality and morbidity worldwide. Anethum graveolens (dill) is one of the recommended herbs to reduce bleeding. Objectives: This study aimed to evaluate the efficacy of rectal suppository of Anethum graveolens on the postpartum hemorrhage (PPH). Methods: Following a randomized clinical design, 70 eligible pregnant women admitted for vaginal delivery to Umm-al-Banin Hospital in Mashhad (Iran) in 2018 were recruited in this trial. Subjects were selected by available method and randomly assigned into two groups of intervention and control. Both groups, immediately after the delivery, received routine hospital interventions. Instantly after the expulsion of the placenta, the intervention group received the first dose of rectal suppository and the subsequent doses up to five doses at intervals of 30 min. PPH was measured by weighing the blood bags and pads for 4h after labor. Data were collected using a sample selection checklist, demographic and pregnancy information forms, birth, infant, and placenta information forms, and partograph sheets. Data were analyzed by SPSS version 22 using an independent t-test or the Mann-Whitney test. Results: The two groups were homogeneous in terms of mediating variables. The mean bleeding rate at the end of the first fourth after delivery was 306.2 ± 11.2 cc in the control group and 282.4 ± 9.6 cc in the intervention group. Therefore, there was a statistically significant difference concerning post-delivery bleeding between the two groups (P = 0.001). Conclusions: Based on the findings, the rectal suppository of Anethum graveolens could effectively reduce the PPH without any adverse effects. Therefore, this efficient herbal approach is suggested to overcome the PPH.

Published: April 2021

Background: Dermoscopic features of cutaneous squamous cell carcinoma (cSCC) have been widely studied, but their accuracy should be further investigated.

Objectives: This study assessed the diagnostic accuracy of a set of predetermined dermoscopic structures for 3 variants of cSCC, namely Bowen disease, keratoacanthoma and invasive cSCC.

Methods: Dermoscopic images of 56 histopathologically confirmed cSCC lesions (9 Bowen disease lesions, 7 keratoacanthomas, and 40 invasive cSCCs) were examined, and the diagnostic accuracy of dermoscopic structures was assessed. Discriminative ability of statistically significant positive predictors was determined using receiver operating characteristic (ROC) curves, and defined as an area under the ROC curve >0.700.

Results: Dermoscopic structures with statistical significance and discriminative ability were: for Bowen disease, clustered glomerular vessels and erosions; for keratoacanthoma, a central keratin plug; and for invasive cSCC, a mixed color of the background. Clustered and glomerular vessels had, for Bowen disease, perfect diagnostic accuracy, with: sensitivity of 88.9% for both features; specificity of 97.9% and 93.6%, respectively; positive predictive value (PPV) of 88.9% and 72.7%, respectively; and negative predictive value (NPV) of 97.8% for both. Erosions had, for BD, high specificity (87.2%) and NPV (91.1%), but low sensitivity (55.6%) and PPV (45.5%). A central keratin plug had, for keratoacanthoma, high specificity (87.8%) and NPV (93.5%), but low sensitivity (57.1%) and PPV (40%). A mixed background color had, for invasive cSCC, high specificity (81.3%) and PPV (89.7%), but low sensitivity (65%) and NPV (48.2%).

Conclusion: Dermoscopy accurately differentiates BD, through clustered glomerular vessels, from keratoacanthoma and invasive cSCC. Dermoscopic structures of keratoacanthoma and invasive cSCC overlap, and only histopathologic analysis differentiates them precisely.
Ordinary and Extraordinary
Authors: Bracken W. Jerome ,   The National Catholic Bioethics Center
Published: April 2021

A theological and historical background is needed for understanding the terms ordinary and extraordinary regarding the care required for one seriously ill. This background is theological, since one’s care is directed to our life on earth and our ultimate happiness that comes from God. So, one needs the knowledge given by God in revelation and in natural law written in our hearts. Besides our own powers of acting, we need the help of others as well as of God, through his grace and sacraments. The historical view is given because situations change, and so our judgment must change. In God’s law, one must eat to live but not if it becomes a torture. Domingo de Soto gave the name ordinary for the former and extraordinary for the latter. With the arrival of anesthesia and antiseptics, the pain and terrible outcomes, which made amputation an extraordinary means, no longer did so.
The Loss of Language, The Language of Loss
Authors: Atchley J. Heath ,   Philosophy Documentation Center
Published: April 2021

This essay is a philosophical reading of Don DeLillo’s novel, The Body Artist, and his essay, “In the Ruins of the Future.” Focusing on the issues of loss, mourning, and terror after the attacks of September the 11th, I argue that DeLillo gives a picture of mourning as something that occurs through a loss of language. This loss does not end language; instead, it occurs through language.

Results of an empirical study on the effectiveness of urgent measures in the Republic of Serbia
Authors: Bošković Aleksandar , Kesić Tanja
Published: April 2021

Contemporary legislation, not only criminal and criminal proceedings law, has entered a new stage, that is currently underway and that is reflected in significant reforms and new legislation, as well as seeking new solutions to increase efficiency in preventing and combating domestic violence. The Republic of Serbia embarked on this path by adopting the Law on Prevention of Domestic Violence, which should primarily intensify the preventive action of the competent state bodies in cases of domestic violence. The Law on Prevention of Domestic Violence started to be applied on June 1, 2017 and given the fact that it has been applied for the past three years, it is necessary to carry out an adequate analysis and to evaluate whether it has increased efficiency when it comes to combating domestic violence. In this regard, the subject of this paper is primarily the analysis of the practical application of urgent measures provided by the Law imposed by the police, the public prosecutor and the court. This research will cover a period of two years of applying of the law, i.e. the period from June 1, 2017 to May 31, 2019. During the research, the statistical method was used along with the methods of analysis, deduction, comparison and description. The paper will analyse: both the total and the individual number of urgent measures imposed by the police; territorial distribution of the imposed urgent measures on the territory of the Republic of Serbia; imposing of extended urgent measures by the court, and a significant aspect of this research will be dedicated to the issue of violations of the imposed urgent measures.
Russian information operations in the Ukrainian armed conflict
Authors: Putnik Nenad , Milosavljević Branislav
Published: April 2021

The ultimate goals and basic forms of social conflict have remained unchanged throughout history. Nevertheless, today there is an evident expansion in the application of new methods, techniques and means for waging war. The continuous fusion of revolutionary achievements in the field of computers, satellite communications and the media has radically improved the possibilities of warfare, despite the fact that technological achievements have not substantially changed the geostrategic and political-economic goals of the war itself. Cyberspace provided enormous opportunities for conducting special propaganda actions as well as for carrying out attacks via computer networks on enemy information systems and thus expanded the space for conducting information operations. Information operations can be conducted independently or in support of conventional, kinetic, conflict. The authors of the paper point out the importance that information operations have in modern armed conflicts on the example of the conflict in Ukraine. In the introduction, an overview of different conceptual definitions of information operations is given. Then, an analysis of the Russian theoretical and strategic-doctrinal approach to information warfare was conducted. After that, the specifics of information operations from the point of view of their content, scope, place and role in modern armed conflicts, on the Ukrainian example, are explained. The paper should be viewed as a starting point for a broader discourse, because it is not possible to discuss this issue comprehensively in all its complexity within the given format. The dramatic events in Ukraine have unequivocally indicated to us that the information aspect of the hybrid war should not be underestimated or neglected.

Neurofibromatoses are a set of different genetic disorders that have a common characteristic of the appearance of nervous system tumors. There are three forms of the disease, of which type 1 neurofibromatosis (NF 1) is the most common. NF 1 is an inherited autosomal-dominant disease, with a high rate of new mutations. In addition to the many physical manifestations and complications that occur in persons with NF 1, there are also numerous cognitive difficulties, including lower general intellectual functioning, learning difficulties, but also problems in attention, visual abilities, executive functions, and speech. Attention disorders are up to three times more common in people with NF 1, while learning disabilities are present in more than half of these subjects. Disturbances in the field of visuospatial perception are recognisable even in the preschool period. About 80% of children with NF1 exhibit various speech and language disorders: slow early speech development, slower vocabulary enrichment, syntactic, semantic and phonological speech disorders. Disruption of executive functions will manifest itself in the areas of working memory, organisation, planning / problem solving. This will reflect as the underperformance in academic achievement. Nearly one-third of these persons have emotional and social problems.
The performance of police duties in the context of the principles governing the operation of the state administrative authorities
Authors: Bulatović Petar
Published: April 2021

Police duties represent a part of the internal affairs performed by the Police, by applying the police authority, measures and actions. The new concept of combating crime is based on the preventive activities of the police and judiciary. In this sense, the police affairs can be approached from different aspects. The primary role of the police is in the criminal and misdemeanor procedure, but, as it can be concluded in the text of this paper, the administrative activities of the police in preventing, detecting, and solving criminal acts, misdemeanors, and other crimes are also very important. So, the paper deals with the issues that significantly helped the main topic of this research paper to be analyzed in the best possible way. This paper analyzes the issues related to the affairs of the Ministry of Internal Affairs, the organization and competence of the police, the principles of operation of the state administrative bodies, police affairs and criminal and misdemeanor procedure as well as administrative activities of the police in preventing, detecting and solving crimes and other offenses. The primary legal texts being consulted were the Law on Police and the Law on State Administration, in addition to consulting two important rulebooks in this area - the Rulebook on police powers and the Rulebook on the manner of performing individual police duties.

The aim of this study is to analyze how the process parameters affect the mechanical properties of butt joints obtained by friction stir welding (FSW). The experimental study was performed by the FSW of sheets having a thickness equal to 6 mm and made of aluminum alloys AA2024 T351, varying the process parameters, namely rotational speed and welding speed. The following welding parameters were used: the rotation speed of the tool did not change and amounted to 750 rpm, and the welding speed was 73, 116,150 mm / min. The welds were obtained without the presence of errors and with an acceptable flat surface of the compound. Tensile tests were performed orthogonally to the welding direction on specimens having the welding nugget placed in the middle of gage length. Vickers hardness measurement was conducted perpendicular to the welding direction, a cross-section of the weld joint. The hardness profiles were obtained along 3 horizontal and 63 vertical directions. Bend testing was carried out according to EN 910 The bending specimens were tested using face and root side of the joint in tension.
Algebraic Algorithms for Betweenness and Percolation Centrality
Authors: Tumurbaatar Altansuren , Sottile Matthew
Published: April 2021

In this paper, we explored different ways to write the algebraic version of betweenness centrality algorithm.
Particularly, we focused on Brandes' algorithm [Brandes, Journal of Mathematical Sociology, 2001]. We aimed for algebraic betweenness centrality that can be parallelized easily. We proposed 3-tuple geodetic semiring as an extension to the usual geodetic semiring
with 2-tuples [Batagelj, Journal of Mathematical Sociology, 1994]. Using the 3-tuple geodetic semiring, Dijkstra's and Brandes' algorithm, we wrote more concise and general algebraic betweenness centrality (ABC) algorithm which is valid for weighted and directed graphs. We also proposed an alternative version of ABC using the usual geodetic semiring with 2-tuple where we used a simple way to construct shortest path tree after computing shortest path distances in the usual geodetic semiring. This allows us to avoid computational complexity of ABC implementation using 3-tuple geodetic semiring. We used numba [Lam et al., LLVM'15, 2015] to optimize and parallelize ABC. We evaluated the performance of ABC using 2-tuple geodetic semiring as compared to NetworkX [Hagberg et al., SciPy 2008, 2008], a common python package for graph algorithms. We did scalability experiments on parallel ABC and showed its total speedup. We also showed that with small modification, ABC can be adapted to algebraicly compute other centrality measures such as percolation centrality.
Schematic Representation of Large Biconnected Graphs

Published: April 2021

Suppose that a biconnected graph is given, consisting of a large component plus several other smaller components, each separated from the main component by a separation pair.
We investigate the existence and the computation time of schematic representations of the structure of such a graph where the main component is drawn as a disk, the vertices that take part in separation pairs are points on the boundary of the disk, and the small components are placed outside the disk and are represented as non-intersecting lunes connecting their separation pairs.
We consider several drawing conventions for such schematic representations, according to different ways to account for the size of the small components.
We map the problem of testing for the existence of such representations to the one of testing for the existence of suitably constrained $1$-page book-embeddings and propose several polynomial-time algorithms.

Published: April 2021

Introduction: Crowd logistics is a widely accepted concept in times of the growing popularity of sharing economy solutions. The popularity of e-commerce and a tendency to provide same-day delivery are the main reasons for their development. Developing those trends requires new products and services, now available on the market, known in the transport area as crowd logistics solutions. Purpose: The purpose of the paper is to provide a tool for assessing crowd-logistics solutions, taking into consideration customers’ requirements. The text includes groups of environmental, economic, and social criteria to facilitate the choice of the best crowd logistics solution for freight transport. Methodology: The research is based on the critical analysis of different sources (literature, European Commission reports, other reports and analyses) and practical solutions in the field of crowd logistics. The main data analysis method is the Analytic Hierarchy Process, usually used to evaluate variants in decision-making processes. This method was chosen because of the variety of data types (quantitative and qualitative) and formats, its popularity, universality, and replicability. Results: This paper contains ready-to-use weights for the assessment of crowd logistics solutions. The proposed set of criteria and weights can be a useful tool for customers to evaluate the sharing- -economy services landscape in the areas they manage.
Albania, the human factor and sustainable development: a lesson from the present
Authors: Arta Musaraj
Published: April 2021

Albania as all Balkan countries in general, in the past 20 years faced with deep and continuous socio-economic change which resulted not simply in a totally newly shaped economy, but also in new and unexperienced paths of human resources developments. This referring to the qualitative, quantitative and diversification terms, brings the age of new professions and connections between the academic development and advancement and the adaption with the real necessities of the labor market. Adding to this complex and mobile situation the effect on their economy of the last financial crisis, the turbulence level is expected to be increased . Practitioners and researchers must understand connections and make up different scenarios which will face with a very unpredictable environment. Not surprisingly, Albania as some other southwestern European countries, due to the low level of integration into the international financial market, their mainly domestic market for goods and services produced by them, did not suffer the same consequences as other neighboring countries. But even the effect of downsizing their economies will affect Albanian economy too, because the payment balance and foreign trade balance as well as due to the widening of globalization in its domestic economy, which Albania cannot afford to avoid any longer. At the same time, the country must take in consideration the economic structure change and its adoption with the EU countries economic structure. These two main challenges can be afforded with substantial foreign investments and the most attractive resource has proved to be the human one. Sustainable development of human resources for a national sustainable development, requires making pro-active decision regarding their development and planning. The welfare of countries more and more is not being measured by the GDP pro capita, instead it is being used the term” life quality” which calls for decision making process aiming to increase and not simply exploit, which pro-actively develops qualitative human resources . This because a major factor for development is direct foreign investment. This drives Albania as well as other Balkan countries shift from naturally gifted with human resources due to the high nativity toward having attractive human resources in terms of quality and diversity related to actual and future trends of economy structuring and development. The paper deals with issues related to economic and human development by comparing two major factors in the case of Albania: the quality of human resources, role of foreign investments in the Albanian economic development and effects of human resources have on them and the careful planning of human resources development driven by actual and future trends of economic development. At the same time, the paper analyses the necessity to link the didactic offer of universities and high schools and market driving forces.
