Market Orientation of Theatres in Bosnia and Herzegovina

Market orientation has lately become one of the major research issues in Bosnia and Herzegovina, mainly because of the country transition to market economy. This process requires essential changes in business behavior of organizations which need to become market oriented. Our study measures the level of market orientation of theaters in Bosnia and Herzegovina. We tried to find out up to which level theaters in Bosnia and Herzegovina implement activities known as intelligence generation, intelligence dissemination and responsiveness. Research results show that the level of market orientation is, according to three MARKOR subscales, low. Theaters collect information from their environments and they have a certain process of organizational communication which results in the level of functional compatibility of (re)actions aimed to the market. Nevertheless, the conclusion is that all the analyzed activities are in their early stages of development.market orientation, business behavior

Ethnocentrism and Animosity in Consumer Behavior in Bosnia and Herzegovina and Implication for Companies

This study attempts to examine ethnocentrism of B&H consumers, animosity tendencies, and consumers' notions of products originating from two neighboring countries - Croatia and Slovenia.The aim is to expose the causal relation between the expression of an individual's animosity,her/his understanding of neighboring countries' image, and her/his degree of ethnocentrism. Klein, Ettenson and Morris (1998)argued that animosity (one of COI-Country of Origin Image aspects) affects consumer behavior, but not the assessment of products originating from this country. This study seeks to examine this argument. The regression analysis confirmed this assumption on a sample of 300 B&H consumers. Additionally one marketing scale and one psychological scale were used: one for measuring consumer ethnocentrism, and the other for measuring country of origin image. This study used the method of mall intercepts - intercepting customers in large shopping malls. Data was processed using ACNOVA, Cronbach alpha and hierarchical regression analysis

The relative contribution of war experiences and exile-related stressors to levels of psychological distress among Bosnian refugees.

This study examined the relative contribution of 2 exile-related variables-social isolation and daily activity level-and war experiences of violence and loss, to levels of PTSD and depressive symptomatology in 2 groups of Bosnian refugees, 1 clinical group (N = 59) and the other a nonclinical community (N = 40) group. As hypothesized, exposure to war-related violence was highly predictive of PTSD symptoms in both groups; in addition, social isolation was significantly related to PTSD symptomatology in the community group. In contrast, depressive symptomatology was accounted for primarily by the exile-related stressors. For the clinical group, depressive symptoms were also accounted for by experiences of war-related loss. The implications of these findings for mental health interventions with refugees are considered. KEY WORDS: war; exile; distress. Indtroduction Research on the mental health of refugees has focused primarily on understanding the etiological role of premigration, war-related experiences in the development of posttraumatic stress disorder (PTSD) and major depressive disorder (MDD), the two most frequently documented psychiatric syndromes in studies of refugee population

Antibiotic hyper-resistance in a class I aminoacyl-tRNA synthetase with altered active site signature motif

Antibiotics target key biological processes that include protein synthesis. Bacteria respond by developing resistance, which increases rapidly due to antibiotics overuse. Mupirocin, a clinically used natural antibiotic, inhibits isoleucyl-tRNA synthetase (IleRS), an enzyme that links isoleucine to its tRNAIle for protein synthesis. Two IleRSs, mupirocin-sensitive IleRS1 and resistant IleRS2, coexist in bacteria. The latter may also be found in resistant Staphylococcus aureus clinical isolates. Here, we describe the structural basis of mupirocin resistance and unravel a mechanism of hyper-resistance evolved by some IleRS2 proteins. We surprisingly find that an up to 103-fold increase in resistance originates from alteration of the HIGH motif, a signature motif of the class I aminoacyl-tRNA synthetases to which IleRSs belong. The structural analysis demonstrates how an altered HIGH motif could be adopted in IleRS2 but not IleRS1, providing insight into an elegant mechanism for coevolution of the key catalytic motif and associated antibiotic resistance.ISSN:2041-172

Noninvasively recorded high-gamma signals improve synchrony of force feedback in a novel neurorehabilitation brain–machine interface for brain injury

Objective.Brain injury is the leading cause of long-term disability worldwide, often resulting in impaired hand function. Brain-machine interfaces (BMIs) offer a potential way to improve hand function. BMIs often target replacing lost function, but may also be employed in neurorehabilitation (nrBMI) by facilitating neural plasticity and functional recovery. Here, we report a novel nrBMI capable of acquiring high-γ(70-115 Hz) information through a unique post-traumatic brain injury (TBI) hemicraniectomy window model, and delivering sensory feedback that is synchronized with, and proportional to, intended grasp force.Approach. We developed the nrBMI to use electroencephalogram recorded over a hemicraniectomy (hEEG) in individuals with TBI. The nrBMI empowered users to exert continuous, proportional control of applied force, and provided continuous force feedback. We report the results of an initial testing group of three human participants with TBI, along with a control group of three skull- and motor-intact volunteers.Main results. All participants controlled the nrBMI successfully, with high initial success rates (2 of 6 participants) or performance that improved over time (4 of 6 participants). We observed high-γmodulation with force intent in hEEG but not skull-intact EEG. Most significantly, we found that high-γcontrol significantly improved the timing synchronization between neural modulation onset and nrBMI output/haptic feedback (compared to low-frequency nrBMI control).Significance. These proof-of-concept results show that high-γnrBMIs can be used by individuals with impaired ability to control force (without immediately resorting to invasive signals like electrocorticography). Of note, the nrBMI includes a parameter to change the fraction of control shared between decoded intent and volitional force, to adjust for recovery progress. The improved synchrony between neural modulations and force control for high-γsignals is potentially important for maximizing the ability of nrBMIs to induce plasticity in neural circuits. Inducing plasticity is critical to functional recovery after brain injury

Hemicraniectomy in Traumatic Brain Injury: A Noninvasive Platform to Investigate High Gamma Activity for Brain Machine Interfaces

Brain-machine interfaces (BMIs) translate brain signals into control signals for an external device, such as a computer cursor or robotic limb. These signals can be obtained either noninvasively or invasively. Invasive recordings, using electrocorticography (ECoG) or intracortical microelectrodes, provide higher bandwidth and more informative signals. Rehabilitative BMIs, which aim to drive plasticity in the brain to enhance recovery after brain injury, have almost exclusively used non-invasive recordings, such electroencephalography (EEG) or magnetoencephalography (MEG), which have limited bandwidth and information content. Invasive recordings provide more information and spatiotemporal resolution, but do incur risk, and thus are not usually investigated in people with stroke or traumatic brain injury (TBI). Here, in this paper, we describe a new BMI paradigm to investigate the use of higher frequency signals in brain-injured subjects without incurring significant risk. We recorded EEG in TBI subjects who required hemicraniectomies (removal of a part of the skull). EEG over the hemicraniectomy (hEEG) contained substantial information in the high gamma frequency range (65-115 Hz). Using this information, we decoded continuous finger flexion force with moderate to high accuracy (variance accounted for 0.06 to 0.52), which at best approaches that using epidural signals. These results indicate that people with hemicraniectomies can provide a useful resource for developing BMI therapies for the treatment of brain injury
