Authors: La Red Martinez David L. , Acosta Julio C.
Published: February 2019

In the groups of processes in distributed systems is necessary to make decisions based on agreements; these processes may operate in distributed teams; processes may require the use of shared resources in the form of mutual exclusion. The following question arises: what decision models will be necessary to generate incorporating the cognitive perspective (mechanisms of self-regulation, autonomy, referential circularity, etc., should take into account; it is required to incorporate these aspects through variables and procedures added to the variables and procedures of the classical computer science; new models that improve the performance of the classics, incorporating new concepts, variables and procedures, will generate [18], [12], [20], [21], [22], [58]) to classical models, which transcend the traditional approach to the computer science? (are considered classical models for access to data structures shared in the form of mutual exclusion using critical regions (from memory), the centralized algorithm, the Lamport distributed algorithm, improved by Ricart and Agrawala, token ring algorithm, among others [49], [51], [52], [54], [55], [56]).

Published: February 2019

We are facing the challenge of increasing application of new technological solutions in the public administration among which are the concept of ontology and the increasing exchange of knowledge and information with which we deal in this paper. This should be the primary drivers of power for the transition of work of the public administration to the new concept of e-m-i-Government. In this paper we perceive the IT situation in this region, development trend of ontology in the public administration and we suggest the solutions for public administration in Bosnia and Herzegovina to implement new solutions. In this paper we suggest the process organization of work and serving in the public administration as a basis for more efficient and more effective implementation of ontologies and the exchange of knowledge with the use of new technological solutions. Likewise, we propose the solution which is based on a single access point for all service users regardless of the communication channel. The implementation of ontologies and intelligence in the public administration will observe as the basis for offering services, personalization and self-service.

E- government and innovation in Italian Public Administration: A business approach
Authors: Comite Ubaldo
Published: February 2019

E-Government consists of a strategic instrument for re-formulating the organization and the operation of Public Administrations, acting as a catalyst of trends and changes. It not only represents a resource that allows economic and operational advantages to be obtained, but is also an instrument that is capable of modifying the pre-existing operational mechanisms of the organization, guaranteeing a fast adaptation to continuous changes in the external environment. The use of e-Government not only facilitates the internal activities of the Public Administration, but also has the advantage of facilitating the relationship between different administrations, as well as the interaction with citizens and with businesses. The impact that e-Government can have is that of a better Public Administration, in that it allows public policies to be optimized, the quality of services to be raised, the involvement of the citizens to be widened, and other specific fundamental activities to be improved.The present work intends to illustrate the comprehensive framework of the public administration system in Italy and of the main tendencies in progress, paying particular attention to the development of new management logic, considering e-Government not only as a merely technological phenomenon, but also analyzing it in its full meaning with regards to the process of change and modernization of the public administration.
Effect of employee demographic characteristics and job characteristics on job satisfaction among employees in the banking industry: A case of commercial banks in Nakuru Town, Kenya
Authors: Ngigi Elizabeth Wanjiru , Kipkebut Dinah Jeruto
Published: February 2019

The banking industry in Kenya is operating in an environment that is becoming increasingly complex due to increased competition, rapid technological changes, globalisation and growth of alternative banking institutions. In order for the banks to achieve success and to satisfy their customer needs, they must attract and retain a satisfied workforce as a source of competitive advantage. The objective of the present study is to examine the effects of demographic characteristics (age, gender, marital status, education, tenure and bank sector) and job characteristics (namely; job autonomy, job variety, role stress, co-worker and supervisory support) on job satisfaction among employees in commercial banks in Nakuru Town in Kenya. The sample of the study consisted of 126 employees drawn from a population of 180 employees from three (3) locally owned banks and five (5) foreign-owned banks. Questionnaires were used to collect data which were analysed using inferential statistics which included Independent Samples T-Test, One Way Analysis Of Variance (ANOVA), Pearsons Correlation and Multiple Regression analysis. The results showed that (a) demographic characteristics partially influenced job characteristics and job satisfaction; (b) Job autonomy, job variety, co-worker and supervisory support had significant, positive effects on job satisfaction; (c) Role stress did not have a significant effect on job satisfaction. The study recommends that bank managers adopt various managerial interventions in order to create a pleasant and supportive work environment in which job satisfaction will thrive.

A study on pre-retting and post-retting water of waterbodies from a selected area of Bangladesh
Authors: Akhter Md. Shamim
Published: February 2019

The study was conducted to analyze the pre and post-retting water of five randomly selected ponds regarding the parameters viz. BOD5, COD, TSS, TDS, TKN, TP, CI, PH, Ec PH, and EC. BOD5 (ranging from 110 to 215 mg/l and 170 to 237 mg/l, respectively)and COD (227 mg/l to 310 and 299 to 403 mg/l, respectively)values of both pre and post-retting water of all the ponds were much higher than recommended values. Values of TSS, TKN, TP tests of both pre and post-retting water of the ponds reflected higher values than recommended values. Whereas, TDS(213 to 501 mg/l and 210 to 595 mg/l, respectively) and Cl (51 to 300mg/l and 50 to 305 mg/l, respectively) values were less than recommended values. PH values were within the recommended range of PH 6 to PH 9. All these results indicates that jute-retting is may not be the one and only factor to deteriorate the water quality of ponds. Jute-retting causes transitory water pollution in the water bodies only which can be minimized or removed by different ways. To find out specific way(s) to minimize or eradicate this transitory pollution  further research is required.

Published: February 2019

SauvignonBlanc wine grape was characterized for their various morphological, physiological and biochemical parameters grafted on different rootstocks. Significant differences were recorded for all the parameters studied. The studies on vegetative parameters revealed that the rootstock influences the vegetative growth thereby increasing the photosynthetic activities of a vine. The highest photosynthesis rate was recorded in 140-Ru grafted vine followed by Fercal whereas the lowest in Salt Creek rootstock grafted vines.The rootstock influenced the changes in biochemical constituents in the grafted vine thereby helping the plant to store enough food material. Significant differences were recorded for total carbohydrates, proteins, total phenols and reducing sugar. The vines grafted on1103-Pshowed highest carbohydrates and starch followed by 140-Ru,while the least amount of carbohydrates were recorded in 110-R and Salt Creek grafted vines respectively.Among the different rootstock graft combinations, Fercal showed highest amount of reducing sugar, proteins and phenols, followed by 1103-P and SO4, however, the lowest amount of reducing sugar, proteins and phenols were recorded with 110-R grafted vines.The vines grafted on different rootstocks showed changes in nutrient uptake. Considering this, the physico-biochemical characterization of grafted vine may help to identify particularrootstocks combination that could influence a desired trait in commercial wine grape varieties after grafting.

Published: February 2019

The objective of this study was to find a rapid determination of the freshness of tomato (Solanum lycopersicum L.) and pepper (Capsicum annuum L.)fruits using portable chlorophyll fluorescence imaging instrument. To assess the fresh quality of tomato and pepper fruits, an imaging anlaysis of the photochemical responses of pericarp or exocarp of tomato and pepper fruits was performed with fruits preserved under the different storage conditions. The observed chlorophyll imaging photos were numerically transformed to the photochemical parameters on the basis of chlorophyll fluorescence.The storage conditions for fruits were regulated as follows; room temperature (control), heat (42°C), wet (25°C and 80% relative humidity), and chilling (4°C) conditions.

Chlorophyll fluorescence imaging (CFI) method showed that the decrease in Fv/Fmratios of pepper fruits was lower at room temperatureand under wet condition than the other conditions. Although Fv/Fmratios and Î¦PSII values in tomato fruits showed low fluorescence responses, the changing patterns have permitted to determine th freshness. In heat condition, the photochemical parameters calculated from the images of Fv/Fm ratios, Î¦PSII and non-photoquenching (NPQ) were also available to determine the freshness of fruits. In our study, it was clearly indicated that the chillingcondition was the suitable condition for thelong storage of tomato and pepper fruits. The CFI analysis is applicable as a rapid screening method for the determination of freshness of tomato and pepper fruits.

Published: February 2019

The açaí palm (Euterpe oleracea Mart.) is a tree native to the Amazonia. In some states in the region, growth of the planted area has been observed, but the difficulty in obtaining substrates which are viable for the production of seedlings is high. It was intended in a first step to evaluate the effect of seed size and substrates upon germination and in the second step, to evaluate the initial growth of seedlings of E. oleracea on different substrates. The experimental design was a completely randomized design in 2 x 2 factorial scheme with four replications at 100 seeds. Germination percentage, percentage of abnormal seedlings, shoot and root length and dry weight of the seedlings were evaluated after 70 days. In the second step, completely randomized design in 9 x 6 factorial scheme with five replications with four seedlings/ plot was utilized. At 60, 90 , 120 , 150 , 180 and 210 days after transplanting, shoot height and diameter of the stem of the plant were assessed, number of leaves were determinate at 90, 120 , 150, 180 and 210 dat and at 210 dat, determinations of dry weight of the shoot and root system were conducted. These samples were put in an oven with forced air circulation at 60 ºC for 72 hours. Açaí seeds considered large present greater germination percent as compared with small seeds and the substrate sand provides greater percentage of seed germination. The substrates composed of 75% (soil+sand) + 25% manure and with 75% (soil+sand) + 25% carbonized rice husk present better development of açai seedlings.
Hidden Gender Violence in the War on Organized Crime in Ciudad Juarez, Chihuahua, Mexico (2010-2011)
Authors: Ortega Rosalba
Published: February 2019

Militarization[1] in this country Mexico is a fundamental factor of political definition due to the loss of life[2] that it has represented, and the impact on public life stemming from the constant violation of the human rights of men, but especially for women, who have both seen their everyday life modified. This fight against organized crime, some have defined it as a war against the people, which pretends to be a war on drug trafficking. In Ciudad Juarez, we already know that the presence of the army and police on the streets does not increase safety, and instead, gender violence is exposed in deaths that occur constantly, so that militarization and impunity are the key to reading the new events as part of a hegemonic project, in which the bodies and humanity are no longer relevant.

Published: February 2019

The objective of this work was to evaluate the effects of forest conversion at to agricultural production on some biological indicators to quantify their relationship in subtropical ecosystems. The experimental design was in romized complete blocks, with four treatments: subtropical rainforest (F), yerba mate crops (I) (Ilex paraguariensis SH.); citrus crops (C) (Citrus unshiu Marc.); tobacco crops (T) (Nicotiana tabacum L.). Soil samples were taken from 0-0.10, 0.10-0.20, 0.20-0.30m deep. The variables measured were: APA, clay content, pH, total nitrogen (N), available phosphorus (P), respiration (RE) soil organic carbon (SOC). These soils showed an acid reaction clay content over 650 g.kg-1. SOC N content were higher in soils under subtropical rainforest, intermediate under citrus crops, lower under tobacco yerba mate crops. The highest APA was found under subtropical rainforest decreased in the three depths. In all treatments, APA was higher in the superficial layer; the 76% of APA variability was explained by N P. APA can indicate changes in soil quality, when comparing subtropical rainforest to agricultural systems. APA does not indicate effects between soils under different crops. Our data suggest that acid phosphatase activity is closely associated to soil nitrogen organic content as energy source.Â

Published: February 2019

A two-years old male mixed breed dog weighing 11 kg was brought to the Veterinary Teaching Hospital by its owner because he noticed a pigmented skin zone with a mass lateral to the penis. The patient was in good clinical condition. On clinical examination, only one testicle was found within the scrotum, and a mass lateral to the right site of the penis was present; upon palpation, the mass was presumed to be a testicle. An ultrasound examination confirmed the presence of an ectopic testicle in that position. The dog had normal fertility and testosterone levels were normal. The patient underwent bilateral orchiectomy and was discharged the following day. The peculiarity of this case is the presence of two independent scrota, an ectopic testicle and its adnexa passing through the abdominal wall, was not supposed to be due a migration along the typical male gonad path during descent.

Authors: Somkuwar Ramhari , BHANGE MAHADEV A , TAWARE P B
Published: February 2019

Different rootstocks were characterized for their various morphological, physiological and biochemical parameters. Significant differences were observed for most of the parameter studied. Rootstocks such as 110-R, 99-R, Dogridge and 1103-P had significant higher contents of carbohydrates, starch, phenols, proteins and reducing sugar. Rootstocks Dogridge, 110-R and Salt Creek also recorded highest rate of photosynthesis and transpiration rate at singe leaf level, which is an important mechanism in overcoming drought tolerance. Phenolic content in the rootstocks such as Dogridge, 110-Rand V. longii, may help in reducing the incidence of major grape diseases in profitable table varieties, if grafted onto these rootstocks.Â  Thus, the physio-biochemical characterization of rootstock may help to identify particular rootstocks that could influence a desired trait in commercial table or wine grape varieties after grafting.In the present investigation, the rootstocks such as 110-R, 99-R 1103-P and Dogridge recorded the highest value for total carbohydrates, phenols, proteins, reducing sugar and gas exchange parameters which may help these rootstocks in overcoming the incidence of important disease and drought toleranceÂ  and lead to a better rooting percentage.

Authors: Abdullahi Rakiya , S Lihan , R Edward , L S Demie
Published: February 2019

Public concerned about food safety and quality have raised interest in manipulating soil nutrients management strategies that could reduce potential threat on environment and sustain food production. Recently, the application of arbuscular mycorrhizal fungi (AMF)as bio-fertilizer has gained recognition especially, in low-input agriculture. The fungi are known to improve plant nutrition and growth. However, this effect may differ according to soil properties and nutrients concentration. A greenhouse experiment was conducted to investigate the effect of AMF and poultry manure (PM) on growth and nutrients contents in maize compared to chemical fertilizer; and to determine the effect of soil properties on colonization potential of AMF. The experiment consists of 13 treatments combinations in 2 soil types (loam and peat), viz; 6 application rates of composted PM in tones (t) ha-1 (0, 4, 6, 8, 10 and 12) and 2 levels of AMF; inoculated (+AMF) and un-inoculated (-AMF) plus recommended dose of NPK (RD NPK). Un-inoculated plants showed no symptoms of root colonization and recorded no AMF spore under both soils. Addition of PM stimulated AMF colonization and sporulation, the highest root colonization (RC %) and spore counts were recorded at 8 t PM+AMF under loam and 12 t PM+AMF in peat soils. Shoot dry biomass at 8 and 12 t PM+AMF under loam and peat were comparable to RD NPK. Applying 8 and 12 t PM+AMF in loam and peat recorded the highest N& K comparable to RD NPK. However, P content in shoot were statistically higher at 8,10 & 12 t PM+AMF in loam and at 12 t PM+AMF in peat compared to RD NPK. Application of 10 & 12 t PM+AMF in loam significantly decreased plant growth, lowered AMF RC%, and nutrient content (N & K). There was a strong positive correlation between shoot dry biomass and RC % in loam (R2= 0.740 P<0.01) and peat (R2=0.884 P<0.01). From the results of this study, it could be concluded that AMF have increased the efficiency use of PM and their integration have the potential to improve plant growth due to enhanced nutrientsÂ  uptake and stimulated RC% in both soils. Results also indicated significantly higher shoot dry biomass, nutrients content (N, P, & K), spore counts and RC % in loam soil compared to peat, indicating that soil properties has a significant influence on effectiveness AMF.Â

Published: February 2019

A pot experiment was conducted to assess the fate and recovery of urea-N applied to sorghum (Sorghum sudanense) both in the presence and in the absence of sewage sludge. For a better understanding of the interaction between urea N and N originating from sewage sludge, 15N isotope technique was used. 15N-labeled urea was added to soil at 0, 60, 100 kg N.ha-1, and unlabeled sewage sludge was added at 0 and 45 kg N.ha-1. In the absence of sewage sludge, 15N recovery (15NR) was 34% of the 15N- Urea applied at 60 kg N.ha-1. It increased to 55% as the urea N rate increased to 100 kg N.ha-1. Co-application of sewage sludge with the highest dose of urea led to a decrease of urea 15NR by 11% as compared to that in the absence of sewage sludge. Application of sewage sludge significantly improved the immobilization of urea-derived N in soil, from 13 to 42 % and from 24 to 31% of 60 and 100 kg N urea applied respectively. Thus, sewage sludge ensured prolonged and continued availability of fertilizer N to plants thereby leading to reduce N loss and to higher fertilizer use efficiency.
Light Quantum Induces The Measurement Paradox
Authors: Puccini Antonio
Published: February 2019

We learn from Quantum Mechanics that the observation of the microscopic world, the measurement (M) of a quantum object, i.e. a particle, inexorably modifies the physical system we wish to examine.

What happens is that with the M it takes place a reduction of the state vectors, that is the ‘wave function collapse’ of the measured particle.

Why does it happen? No one knows.

The enigma of the so-called Measurement Paradox, in our opinion, could be solved if we considered that the light quantum(LQ), as suggested by the Principle of Equivalence Mass-Energy, carries out a dynamic-mass equivalent to its energy. The LQ is indispensable to carry out a M. 

No M can be carried out without using the quantum of light.

Calculus show that a photon of the optic band hits an electron with a momentum bigger than the mass of the electron itself.

This may explain why the M induces the implosion of the quantum object observed, together with the collapse of its wave function, giving rise to the Measurement Paradox.

Two case studies are analysed and compared. According to the results, the case study based on the combination of a heat pump cycle with an organic Rankine cycle, is the paradigm of a reversible 100% efficient combined cycle. The case study based on a heat pump cycle and a reversible heating-cooling based cycle is the paradigm of a super-efficient combined cycle that yields a 1.486 power ratio (PR) or 148.6% efficiency. Further, the case based on a heat pump cycle with a regenerative irreversible heating-cooling based cycle, is the paradigm of energy conversion and energy generation that yields a 1.29 PR or 129% efficiency assuming limited irreversibilities.

In this work, we studied the structural and magnetic properties of multiferroic La1-xYxFeO3 perovskites, (x= 0.0, 0.05, 0.1, 0.15, 0.25 and 0.3) which synthesized through Sol-gel auto-combustion technique using a citric acid as a fuel. The room temperature synchrotron X-ray diffraction (XRD) analysis revealed that the all the synthesized samples consisted of the polycrystalline orthorhombic structure perovskites(space group pnma), and tolerance factor confirmed the phase stability of the prepared perovskite system.The Williamson-Hall plot based on synchrotron XRD data were employed to estimate the average particle diameter and varies from 18 nmto 27.8 nm.For a deeper insight of the crystal structure, high resolution transmission microscopy imaging (HRTEM) was performed. The estimated values of crystallite size from HRTEM and synchrotron XRD data were coincident. Many of crystallographic parameters and electron density measurements were calculated by Rietveld refinement of synchrotron XRD data. La1-xYxFeO3 perovskite crystalsarecanted antiferromagnets with a weak ferromagnetism in room temperature.The magnetic properties were gotten through analyzing the magnetization versus temperature M(T) and M(H) hysteresis loop which characterized by a vibrating sample magnetometer (VSM). The molecular structure showed the decrease of the tilting of the octahedra  with increasing Y content trying to strengthen the ferromagnetic character. Selected Area Electron Diffraction (SAED) patterns of the investigated samples exhibited spotty ring patterns,confirming the polycrystalline character.The orthoferrite La1-xYxFeO3 crystalsare a promising candidate for optical device applications in broad temperature range and high power system.

The given investigation was undertaken to evaluate the performance of black gram (vigna mungo L.) under different salinity levels (i.e. 50mM, 100mM and 150mM NaCl) and to find out the remedial effect of two doses of S (i.e. 2mM and 4mM) against salinity stress on growth of studied crop by providing tolerance against salinity stress. The experiment was carried out in Botany department, Jinnah University for women, Nazimabad, Karachi, in controlled laboratory condition by using plate culture technique followed as completely randomized design with three replication of each treatment. The observation of given research showed that the percentages of shoot and root length and Fresh and dry seedling weights were higher in control treatment. The low (50mM NaCl) level of salinity treatment had no deleterious effects on plant vegetative growth, while at higher concentration of NaCl (100mM), all the growth parameters were drastically reduced. Both application rates of MgSO4 were found satisfactory to eliminate the negative effect of saline environment inside rhizosphere by promoting plant tolerance against stress thus support treated plants growth and development.

Stains for Cellular Features cellular features such as presence of capsule, spores and flagella were screened using India ink stain which creates a clear zone around the bacteria cell in gram negative strains, and Malachite stain which stains spores green and bacteria cell red. Differential Staining (Gram Staining Procedures) was done in which the bacteria were first stained with crystal violet and then treated with mordant in order to fix the stain inside the cell. Identification of microbial organisms down to species level was done using molecular biology technique by cleavage of microbial DNA Sequence using restriction enzymes (RE).

Results: Results showed that most of the greywaters from these local bathrooms were mainly gram negative bacteria. The most disseminated species are Salmonella typhi, Vibrio cholera, Escherichia coli, Campylobacter jejuni, Staphylococcus aureus and Shigella dysenteriea, according to various restriction enzymes specific to each bacterium. The RE obtained at Collaborative Research Inc. 1365, Main Street, Massachusetts, USA; do show any abnormal cleavage pattern of the DNA sequence during electrophoresis and RE DNA digestion. Most species of the microbes were highly present in greywater from local bathrooms in Maihula, Mayokam and Garbabi. It was however not high in Bali and Suntai. Highest percentage of contamination was seen in Garbabi, Garba-Chede, Jamtari and Daka; with Campylobacter jejuni the dominant bacterium species present.

Conclusion: The results showed that in areas sampled, the greywaters from local bathrooms contained mainly gram negative pathogenic bacteria with potential threat to lives, and Campylobacter jejuni, Vibrio cholera, Salmonella typhi, and E. coli were the dominant organisms.

In this research work, the effect of mound soil on concrete produced with river sand was investigated. A mixed proportion of 1.1.8:3.7 with water cement ratio of 0.47 were used. The percentage replacement of river sand with mound soil is 0%, 5%, 10%, 20%, 30% and 40%. Concrete cubes of 150mm x 150mm x150mm of river sand/mound soil were cast and cured at 3, 7, 28, 60 and 90 days respectively. At the end of each hydration period, the three cubes for each hydration period were crushed and their average compressive strength recorded. A total of ninety (90) concrete cubes were cast. The result of the compressive strength test for 5- 40% replacement of river sand with mound soil ranges from 24.00 -42.58N/mm2 a against 23.29-36.08N/mm2 for the control test (0% replacement).The workability of concrete produced withÂ 5- 40% replacement of river sand with mound soil ranges from 47- 62mm as against 70mm for the control test.

Calpastatin gene, an endogenous inhibitor of calpain enzyme, is important for maintaining muscle texture and postmortem degradation of myofibrils.Â  Present study was carried out for the identification of SNPs in the inhibitory region of calpastatin gene in common carp Cyprinus carpio var. communis for genetic improvement of genotypes. Primers were designed from cDNA sequences of Atlantic salmon (AFV08638.1), Rainbow trout (NP_001118010.1) and cDNA as well as genomic DNA sequences of Zebra fish (NM_001130591.2) to amplify the CAST gene in Common carps. Four exons (13, 14, 19 and 20) and intervening introns demarcated by zebrafish genomic data base of 316 and 311 base pairs were amplified. The sequencing and insilico translation was done for the identification and characterization calpastatin. The results showed that Cyprinus carpio var. communis have two highly conserved sequence motifs DTLPP, GYR repeats in the inhibitory domain which corresponds to the exon-14 and exon-20 of Zebra fish. The single amino acid change in the inhibitory motif G (GGT)/X (X = Q 394aa (CAA) in Danio rio, Sequence ID: ref|NP_001124063.2, E 491aa (GAG) in Salmo salar, Sequence ID: ref|NP_001167162.1, K 223aa (AAG) in Onchorhyncus mykiss long isoform, Sequence ID: ref|NP_001118010.1, and E 54aa (GAG) in Onchorhyncus mykiss short isoform, Sequence ID: ref|NP_001118117.1) have role in the diversification of inhibitory activity of the protein due to species diversification. Another interesting characteristic feature of the inhibitory motif of exon-20 in Common carps having Glysine (GGT) amino acid and rest instead of Glutamic acid (GAG) at 548th aa in Danio rio and 689th aa Salmo salar. It was also observed that Common carp shear (94-95%) CAST gene sequence with Zebra fish while as only (52-54%) sequence homology was observed with Atlantic salmon and Rainbow trout due to species divergence. Phylogenetic analyses of different species revealed telosts are more primitive than tetrapods. Variations observed in inhibitory domain play important role in postmortem proteolysis. Development of markers for meat tenderness and fillet quality based on the mutations in the inhibitory region will help in selecting genotypes of better fillet/texture quality.

The BI is a new trend in public sector organizations that requires investigating the critical success factors (CSFs) which would provide a sound guidelines for determining the criteria to be considered during BI implementation. However, there is no sufficient empirical evidences that provide better understanding of the CSFs for the BI implementation in public sector organizations. This paper aims to identify the CSFs for BI system in the context of public sector organizations. This study adopts a mixed method approach using survey research method and qualitative interview using Jordanian public sector organization case. The findings of this research revealed that top management support, clear vision and strategic planning, team skills, user participation, organizational structure, user access and development technology are the most critical factors to BI implementation success in the public sector organizations. The findings of this study could assist the practitioners in the public sector organizations in planning, managing and implementing their BI projects properly by focusing on those CSFs of BI systems that provide them a better understanding to address issues and concerns related to BI implementation.

Key sectors of Optimal Economic Restructuring Constrained by Environmental Protection: A Structured Input-Output Analysis Approach
Authors: Vaninsky Alexander
Published: February 2019

This paper introduces a tool to discover key sectors of a national or regional economy whose shares should be adjusted to offer optimal economic development constrained by environmental protection. The suggested approach uses an appropriately structured input-output model to find the projected gradient of economic development and the projected antigradient of CO2 emissions. The former is measured as Gross Domestic Product (GDP), the latter, as energy consumption. A linear combination of the two, in a proportion corresponding to the relative importance of GDP and CO2 emissions, determines the direction of optimal economic restructuring. It provides the maximum weighted difference between an increase in the GDP and a decrease in CO2 emissions. The main components of the direction vector show the key sectors. One of the advantages of the suggested approach is its reliance on gross output, final product, and energy consumption only; it does not use the intermediate inputs in the calculations. The United States case study is considered as an example.

Published: February 2019

At present time the world economy is in a very difficult position - on the one hand, the economic indicators in many leading countries of the world proceed to fall; on the other hand, scientists cannot find an explanation for this and bring the countries out of a prolonged recession. All these cause the search for new mechanisms of economy functioning. And it does not require to invent something new, rather "to take a dive" into the economic history of individual states and to identify mechanisms of their successful development. The presented study is an attempt to analyze the reasons of the growth of the Soviet economy (USSR), throughout its development, in the context of organizational changes in the management system.
