The understanding of visitor images is an important subject for tourism destination marketers. Although an increasing number of empirical studies explore images of several tourism destinations worldwide, limited research has been focussed on the tourism destination image of conflict areas. This study examines the image of Bethlehem by analysing Bethlehem's visitors' online publishing. Data was collected from popular travel blog sites, which include online posts about Bethlehem and its visitors' beliefs and evaluations. The results revealed that destination specific attributes in addition to primary image attributes are essential to understand the visitors' image of a conflict area. This study suggests that destination marketers of conflict areas should first accept their unique destination attributes, which do not change rapidly. The visitors' perceptions of Bethlehem and its people are based on more functional and psychological attributes than on holistic impressions. Destination marketers of conflict areas should craft a unique branding strategy that fits their destination best.

This study aims to understand how alternative tourism can contribute to the destination image of Palestine, given its negative image in the media. It proposes a framework for various destination image aspects and applies this framework in the context of alternative tourism in Palestine. It seeks to explore the key image formation factors, the perceived images of Palestine, and the post-visit behaviours of tourists who had engaged in alternative tourism in Palestine. This research contributes in fulfilling intriguing gaps in the Palestinian destination’s image literature, as well as the alternative tourism field that has emerged manifestly in Palestine. This study is exploratory in nature applying qualitative methodology by using open-ended questions in email interviews, and the interviews were analysed using thematic analysis. The empirical results proved that tourists who had visited Palestine and engaged in alternative tourism, had positive destination images, opposite to the ones portrayed in the media that show Palestine as a dangerous place to visit. Finally, this research provides academic and managerial implications.

Neighborhood image processing operations on Field Programmable Gate Array (FPGA) are considered as memory intensive operations. A large memory bandwidth is required to transfer the required pixel data from external memory to the processing unit. On-chip image buffers are employed to reduce this data transfer rate. Conventional image buffers, implemented either by using FPGA logic resources or embedded memories are resource inefficient. They exhaust the limited FPGA resources quickly. Consequently, hardware implementation of neighborhood operations becomes expensive, and integrating them in resource constrained devices becomes unfeasible. This paper presents a resource efficient FPGA based on-chip buffer architecture. The proposed architecture utilizes full capacity of a single Xilinx BlockRAM (BRAM36 primitive) for storing multiple rows of input image. To get multiple pixels/clock in a user defined scan order, an efficient duty-cycle based memory accessing technique is coupled with a customized addressing circuitry. This accessing technique exploits switching capabilities of BRAM to read 4 pixels in a single clock cycle without degrading system frequency. The addressing circuitry provides multiple pixels/clock in any user defined scan order to implement a wide range of neighborhood operations. With the saving of 83% BRAM resources, the buffer architecture operates at 278 MHz on Xilinx Artix-7 FPGA with an efficiency of 1.3 clock/pixel. It is thus capable to fulfill real time image processing requirements for HD image resolution (1080 × 1920) @103 fcps.

The huge number of images shared on the Web makes effective cataloguing methods for efficient storage and retrieval procedures specifically tailored on the end-user needs a very demanding and crucial issue. In this paper, we investigate the applicability of Automatic Image Annotation (AIA) for image tagging with a focus on the needs of database expansion for a news broadcasting company. First, we determine the feasibility of using AIA in such a context with the aim of minimizing an extensive retraining whenever a new tag needs to be incorporated in the tag set population. Then, an image annotation tool integrating a Convolutional Neural Network model (AlexNet) for feature extraction and a K-Nearest-Neighbours classifier for tag assignment to images is introduced and tested. The obtained performances are very promising addressing the proposed approach as valuable to tackle the problem of image tagging in the framework of a broadcasting company, whilst not yet optimal for integration in the business process.

If the ratio m/p tends to zero, where m is the number of factors m and p the number of observable variables, then the inverse diagonal element of the inverted observable covariance matrix (σ pjj) -1 tends to the corresponding unique variance ψ jj for almost all of these (Guttman, 1956). If the smallest singular value of the loadings matrix from Common Factor Analysis tends to infinity as p increases, then m/p tends to zero. The same condition is necessary and sufficient for (σ pjj) -1 to tend to ψ jj for all of these. Several related conditions are discussed. © 2006 The Psychometric Society.

This paper reports on an experiment comparing students’ results on image-rich numeracy problems and on equivalent word problems. Given the well reported problematic nature of word problems, the hypothesis is that students score better on image-rich numeracy problems than on comparable word problems. To test the hypothesis a randomized controlled trial was conducted with 31,842 students from primary, secondary, and vocational education. The trial consisted of 21 numeracy problems in two versions: word problems and image-rich problems. The hypothesis was confirmed for the problems used in this experiment. With the insights gained we intend to improve the assessment of students’ abilities in solving quantitative problems from daily life.

This paper presents a method for generating player-driven narratives from visual inputs by exploring the visual analysis capabilities of multimodal large language models. By employing Bartle’s taxonomy of player types—Achievers, Explorers, Socializers, and Killers—our method creates stories that are tailored to different player characteristics. We conducted a fourfold experiment using a set of images extracted from a well-known game, generating distinct narratives for each player type that are aligned with the visual elements of the input images and specific player motivations. By adjusting narrative elements to emphasize achievement for Achievers, exploration for Explorers, social connections for Socializers, and competition for Killers, our system produced stories that adhere to established narratology principles while resonating with the characteristics of each player type. This approach can serve as a helping tool for game designers, offering new insights into how players might engage with game worlds through personalized image-driven narratives.

Objective: In myocardial perfusion single-photon emission computed tomography (SPECT), abdominal activity often interferes with the evaluation of perfusion in the inferior wall, especially after pharmacological stress. In this randomized study, we examined the effect of carbonated water intake versus still water intake on the quality of images obtained during myocardial perfusion images (MPI) studies. Methods: A total of 467 MIBI studies were randomized into a carbonated water group and a water group. The presence of intestinal activity adjacent to the inferior wall was evaluated by two observers. Furthermore, a semiquantitative analysis was performed in the adenosine subgroup,using a count ratio of the inferior myocardial wall and adjacent abdominal activity. Results: The need for repeated SPECT in the adenosine studies was 5.3 % in the carbonated water group versus 19.4 % in the still water group (p = 0.019). The inferior wall-to-abdomen count ratio was significantly higher in the carbonated water group compared to the still water group (2.11 ± 1.00 vs. 1.72 ± 0.73, p\0.001). The effect of carbonated water during rest and after exercise was not significant. Conclusions: This randomized study showed that carbonated water significantly reduced the interference of extra-cardiac activity in adenosine SPECT MPI.

Medical imaging practice changed dramatically with the introduction of digital imaging. Although digital imaging has many advantages, it also has made it easier to delete images that are not of diagnostic quality. Mistakes in imaging—from improper patient positioning, patient movement during the examination, and selecting improper equipment—could go undetected when images are deleted. Such an approach would preclude a reject analysis from which valuable lessons could be learned. In the analog days of radiography, saving the rejected films and then analyzing them was common practice among radiographers. In principle, reject analysis can be carried out easier and with better tools (ie, software) in the digital era, provided that rejected images are stored for analysis. Reject analysis and the subsequent lessons learned could reduce the number of repeat images, thus reducing imaging costs and decreasing patient exposure to radiation. The purpose of this study, which was conducted by order of the Dutch Healthcare Inspectorate, was to investigate whether hospitals in the Netherlands store and analyze failed imaging and, if so, to identify the tools used to analyze those images.

Public transgressions by group members threaten the public image of a group when outside observers perceive them as representative of the group in general. In three studies, we tested the effectiveness of rejection of a deviant group member who made a racist comment in public, and compared this to several other strategies the group could employ to protect their image. In Study 1 (N¼75) and Study 2 (N¼51), the group was judged less racist after rejecting the deviant than after claiming a non-racist position or not responding to the transgression. Perceived typicality of the deviant partially mediated this effect in Study 2. In Study 3 (N¼81), the group was judged least racist after forcing the deviant to apologize and as most racist after denying the severity of the transgression. Results also showed a negative side-effect of rejection. Perceived exclusion of the deviant contributed to a perception of the group as disloyal to its members, which resulted in a less favorable overall group evaluation. Potential benefits and risks of rejection, denial, and apologies are further discussed in the General Discussion.
