The aim of this paper is to present the application of quantitative methods in the analysis of foreign trade indicators of corn in Bosnia and Herzegovina. Subsequently, based on the analysis, the forecast of import and export parameters was created for the 2018-20 period which predicted that corn imports and exports would increase both in the natural and value form. Furthermore, it was established for the observed period that Serbia was the largest importer of this crop to Bosnia and Herzegovina, and that Turkey was a country to which the corn from Bosnia and Herzegovina was mostly exported. The research in this paper can serve the purpose of further planning and development of both the production and the markets of this crop and agriculture as a whole.

Background Because nearly 23,000 more neurosurgeons are needed globally to address 5 million essential neurosurgical cases that go untreated each year, there is an increasing interest in task-shifting and task-sharing (TS/S), delegating neurosurgical tasks to nonspecialists, particularly in low- and middle-income countries (LMICs). This global survey aimed to provide a cross-sectional understanding of the prevalence and structure of current neurosurgical TS/S practices in LMICs. Methods The survey was distributed to a convenience sample of individuals providing neurosurgical care in LMICs with a Web-based survey link via electronic mailing lists of continental societies and various neurosurgical groups, conference announcements, e-mailing lists, and social media platforms. Country-level data were analyzed by descriptive statistics. Results The survey yielded 127 responses from 47 LMICs; 20 countries (42.6%) reported ongoing TS/S. Most TS/S procedures involved emergency interventions, the top 3 being burr holes, craniotomy for hematoma evacuation, and external ventricular drain. Most (65.0%) believed that their Ministry of Health does not endorse TS/S (24.0% unsure), and only 11% believed that TS/S training was structured. There were few opportunities for TS/S providers to continue medical education (11.6%) or maintenance of certification (9.4%, or receive remuneration (4.2%). Conclusions TS/S is ongoing in many LMICs without substantial structure or oversight, which is concerning for patient safety. These data invite future clinical outcomes studies to assess effectiveness and discussions on policy recommendations such as standardized curricula, certification protocols, specialist oversight, and referral networks to increase the level of TS/S care and to continue to increase the specialist workforce.

U ovom radu sintetisana je serija segmentiranih poliuretanskih materijala primenom dverazličite vrste alifatičnih polikarbonatnih diola, oznaka T5651 (50% pentanskih i 50%heksanskih grupa kao ponavljajućih jedinica) i T4671 (30% butanskih i 70% heksanskihgrupa kao ponavljajućih jedinica u strukturi lanca). Segmentirani termoplastični poliuretanskimaterijali su ojačani nanočesticama glina sa slojevitom strukturom (montmorilonit ibentonit). Ispitivan je uticaj udela tvrdih segmenata i nanopunila na mehanička svojstva iapsolutno izduženje segmentiranih poliuretanskih elastomera i hibridnih materijala. Utvrđenoje da udeo tvrdih segmenata kod uzoraka na osnovu polikarbonatnog diola oznake T5651 neutiče na prekidnu čvrstoću, ali ima značajan uticaj na prekidnu čvrstoću elastomerastrukturiranih primenom polikarbonatne komponente oznake T4671. Smanjenje udela tvrdihsegmenata u znatnoj meri povećava prekidno izduženje. Dodatak 1 mas.% nanočesticaorganski modifikovanog bentonita utiče na znatno povećanje vrednosti prekidne čvrstoće iprekidnog izduženja poliuretanskih elastomera sa polikarbonatnom komponentom oznakeT5651, kao mekim segmentom (od 23.5 do 46.7 MPa i od 420 do 702%, redom). Elastomeristrukturirani primenom diola oznake T4671 i ojačani nanočesticama montmorilonita ibentonita pokazuju pogoršana mehanička svojstva u odnosu na neojačane poliuretane saistom vrstom polikarbonatne komponente kao mekog segmenta. Veću sposobnost izduženjapokazuju poliuretanski materijali strukturirani primenom polikarbonatnog prekursora oznakeT5651, usled veće pravilnosti u strukturi lanca polikarbonatnog diola koji sadrži isti brojpentanskih i heksanskih grupa.

The aim of the study was to evaluate reproductive parameters in a population of the Banija Spotted (BS) pig breed. A total of 69 breeding sows registered in the herdbook were analysed according to the Order of Parity (OP) (1st, 2nd, 3rd, joint 4th and 5th parity, and all parities). Basic descriptive statistical analyses were used to calculate reproductive parameters such as age at mating and farrowing, Age of the Boar (AB) at mating, gestation length and farrowing interval; the following parameters were analysed for Litter Size (LS): Total Number of Born (TNB), Number of Born Alive (NBA), Number of Still Born (NSB) and Number of Weaned (NW) piglets. Analyses were carried out using the GLM procedure in SAS, whereas the Pairwise Pearson PROC CORR procedure was used to calculate correlation coefficients (r) between LS traits. On average 8.26 TNB, 7.57 NBA, 0.67 NSB and 6.95 NW piglets were determined. Significant differences (P<0.05) were observed between 1st and 2nd, and 1st and 3rd OP for TNB and NBA. NW was significantly different (P<0.05) between 1st and 2nd OP, and between 3rd and joint 4th and 5th parities, with a significant (P<0.05) effect of Gestation Length (GL) and Farrowing Season (FS) on NBA in 2nd parity. A significant effect of Herd Group (HG) and AB on NBA was recorded in 3rd OP. Joint 4th and 5th parities with the lowest number of litters analysed showed a significant effect (P<0.05) of AB on TNB, NBA and NW, as well as of GL on NSB. High correlation coefficients (r = 0.7-0.9; P<0.05, per parity analysed) were found between TNB-NBA, TNB-NW and NBA-NW in all parities *Corresponding author: Prof. Krešimir Salajpal, DVM, PhD, Department of Animal Science, Faculty of Agriculture, University of Zagreb, Svetošimunska 25, HR-10000 Zagreb, Croatia, Phone: +385 1 2394 038; E-mail: ksalajpal@agr.hr DOI: 10.24099/vet.arhiv.0428

This study aimed to investigate the facilitative effect of observational practice combined with mental imagery on learning of soccer dribbling. 140 young boys with the average age of 14,52 (±2,96) and mental imagery score of 48,69 (±5,1), who were unfamiliar with the research task, voluntarily participated in this study. The participants were assigned to homogenous groups according to their pre-tests results as follow: 1- physical practice; 2- observational practice; 3-mental imagery practice; 4-physical-observational practice; 5-physical-mental imagery practice; 6- observational-mental imagery practice and 7- physical-observational-mental imagery practice. Then the participants completed three sessions including ninety trials. At the end of the final training session, an immediate retention test was conducted that followed by a delayed retention test after 48 hours. The results of One-Way ANOVA test indicated that in both immediate and delayed retention tests, the physical-observational-mental imagery group and the physical group had a better performance compared with other groups (p<.05). Furthermore, the combined physical-mental imagery group obtained higher scores in soccer dribbling task in comparison with the combined physical-observational group. The findings support the beneficial effects of cognitive interventions as well as physical practice.

The paper aims to empirically explore the impact of the Arabic Spring on the outflow of FDI in twelve selected countries in the North Africa region (Algeria, Tunisia, Morocco, Libya, Egypt and Mauritania) and the Mideast region (Bahrain, Kuwait, Oman, Lebanon, Jordan and the United Arab Emirates). The paper employs a panel data approach to exploit the time series nature of the relationship between FDI Outwards and its determinants (the market size, trade openness, government effectiveness, inflation and three dummy variables related to the Arab Spring) between 2000 and 2016. The findings revealed that the impact of the Arab Spring estimator is negatively correlated with FDI Outflows in the countries that witnessed the Arab Spring. It implies that conflicts and instability negatively affect FDI outflows. The findings of this study reveal that countries that have been affected by the Arab Spring directly (the North Africa region) experienced a greater decline of FDI outflows than countries that have been indirectly affected (the Mideast region). When the sample is restricted to North Africa it is shown that the FDI outflows may be influenced by the post Arab Spring effect, while there is no such statistically significant effect in the Mideast region. Thus, the study finds that FDI outflows in the North African countries are more determined by the effects of Arabic Spring countries than in the Mideastern countries.

Life transitions are an integral part of the human experience. However, research shows that lack of support during life transitions can result in adverse health outcomes. To better understand the support needs and structures of low-income women during transition to motherhood, we interviewed 10 women and their 14 supporters during the transition. Our findings suggest that support needs and structures of mothers evolve during transition, and that they also vary by socio-economic contexts. In this paper, we detail our study design and findings. Informed by our findings, we posit that all life-transitions are not the same, and that therefore, the optimal support intervention point varies for different life transitions. Currently there are no tools available to identify optimal support intervention points during life transitions. To this end, we also introduce a preliminary framework - the Strength-Stress-Analysis (SSA) framework - to identify optimal support intervention points during life-transitions.
