The success of any business depends fundamentally on the possibility of balancing (symmetry) needs and their satisfaction, that is, the ability to properly define a set of success indicators. It is necessary to continuously monitor and measure the indicators that have the greatest impact on the achievement of previously set goals. Regarding transportation companies, the rationalization of transportation activities and processes plays an important role in ensuring business efficiency. Therefore, in this paper, a model for evaluating performance indicators has been developed and implemented in three different countries: Bosnia and Herzegovina, Libya and Serbia. The model consists of five phases, of which the greatest contribution is the development of a novel rough additive ratio assessment (ARAS) approach for evaluating measured performance indicators in transportation companies. The evaluation was carried out in the territories of the aforementioned countries in a total of nine companies that were evaluated on the basis of 20 performance indicators. The results obtained were verified throughout a three-phase procedure of a sensitivity analysis. The significance of the performance indicators was simulated throughout the formation of 10 scenarios in the sensitivity analysis. In addition, the following approaches were applied: rough WASPAS (weighted aggregated sum product assessment), rough SAW (simple additive weighting), rough MABAC (multi-attributive border approximation area comparison) and rough EDAS (evaluation based on distance from average solution), which showed high correlation of ranks by applying Spearman's correlation coefficient (SCC).

Abstract Background Headache is the symptom of pain in the face, head or neck that causes disability in most people with medical and neurological disorders. It frequently co-occurs with most chronic diseases such as epilepsy and significantly impacts the quality of life. However, epidemiologic data from different studies showed different rates of prevalence. Therefore, we conducted this review to summarize the available epidemiologic evidence on the topic and formulate recommendations for future research and clinical practice. Methods We followed the preferred reporting items for systematic review and meta-analysis (PRISMA) guidelines. We systematically searched the literature using popular databases such as PubMed, EMBASE, Psych-INFO, and SCOPUS. We further scanned the reference lists of the eligible studies to supplement our electronic search. The Comprehensive Meta-Analysis software version 3.0 (CMA 3.0) was used to conduct a meta-analysis. Subgroup and sensitivity analysis were performed and Cochran’s Q- and the I2- test were used to assess the source of heterogeneity. The funnel plot and Egger’s regression tests were used to assess potential publication bias. Results A total of 17 studies conducted both in developed and developing countries including 5564 study participants were combined in this meta-analysis. The pooled estimated prevalence of headache among patients with epilepsy was 48.4%. The pooled estimated prevalence of Inter-Ictal headache (IIH) (42.2%) and Postictal headache (PIH) (43.1%) were higher when compared to tension-type headache (TTH) (26.2%), migraine with aura (26.0%) and migraine without aura (10.4%). The pooled prevalence of headache was 50.6% and 49.5% for developed and developing countries respectively. The pooled prevalence of headache among patients with epilepsy was considerably higher among females (63.0%) when compared to males (33.3%). Moreover, the pooled estimated prevalence of headache among patients with epilepsy was ranging from 46.0% to 52.2% in a leave-one-out sensitivity analysis. Conclusion The pooled estimated prevalence of headache among patients with epilepsy was considerably high (48.4%). Screening and appropriate management of headaches among patients with epilepsy are warranted.

Estate Property

The built heritage began to be seen not only as a real estate property and an object of cultural value but also as a multifaceted and multidimensional cultural good in the second half of the 20th century. It has increasingly attracted the interests of economists, who attempted to measure not only its economic impact, but also the total economic value. The spectrum of the categories of the economic value of the built heritage and the valuation methods applied has expanded in the course of time. Currently it encompasses market and nonmarket economic values and numerous valuation techniques based on the stated and revealed data, including the Contingent Valuation method (CVm). The number of contingent valuation (CV) studies aimed at valuing the non-market benefits of the built heritage in developed and developing countries is growing. However, the post-communist transition countries are quite an exception. The applications of the CVm in the developing countries have demonstrated that the sociocultural context must be taken into account and the special measures must be applied in order to get the reliable results. This sensitivity of the CVm to the sociocultural context encourages analyzing the peculiarities of its application in the post-communist transition countries. The main aim of the article is to determine the peculiarities of the social environment of the post-communist transition countries and their possible influence on the CV results. The findings of the research can be useful not only to the fields of CV survey design and benefit transfer, but also to the broad and rapidly developing field of the post-communist studies, for the better understanding the hidden values and potential of the built heritage properties, and the sustainable management of the built environment. Santrauka Antrojoje XX a. pusėje nekilnojamasis kultūros paveldas patraukė ekonomikos srityje dirbančių mokslininkų dėmesį. Bandoma įvertinti ne tik ekonominę paveldo įtaką, bet ir bendrąją jo ekonominę vertę. Laiku bėgant buvo nustatytas platus nekilnojamojo kultūros paveldo teikiamų ekonominių verčių spektras ir plėtojami vertinimo metodai joms nustatyti. Šiuo metu pripažįstama, kad nekilnojamasis kultūros paveldas gali teikti ne tik rinkos, bet ir ne rinkos ekonomines vertes, kurioms nustatyti taikoma nemažai vertinimo metodų, grindžiamų tiek egzistuojančiais rinkų duomenimis, tiek sociologinių apklausų teikiamais duomenimis. Vienas tokių metodų – numatomojo vertinimo metodas. Šis metodas vis plačiau taikomas nekilnojamojo kultūros paveldo ne rinkos vertėms nustatyti tiek išsivysčiusiose, tiek besivystančiose šalyse. Visgi pereinamąjį laikotarpį išgyvenančios postkomunistinės valstybės šiuo požiūriu yra išimtis. Numatomojo vertinimo metodo taikymo besivystančiose valstybėse patirtis parodė, kad, taikant šį metodą, būtina įvertinti sociokultūrinį vietos kontekstą ir imtis papildomų priemonių siekiant vertinimo rezultatų patikimumo ir tikslumo. Sociokultūrinio konteksto įtaka numatomojo vertinimo metodo taikymo galimybėms skatina paanalizuoti šio metodo taikymo ypatumus postkomunistinėse valstybėse. Straipsnio tikslas – išskirti pereinamojo laikotarpio postkomunistinių valstybių socialinės aplinkos ypatumus ir nustatyti galimą jų įtaką numatomojo vertinimo metodo taikymo galimybėms. Tyrimo rezultatai gali būti naudingi ne tik toliau tobulinant numatomojo vertinimo metodą, bet ir sparčiai plėtojamai postkomunistinių studijų sričiai ir siekiant darnaus užstatytos aplinkos vystymosi.
