Workplace Trust

In research on trust in the organizational context, there is some agreement evolving that trust should be measured with respect to various foci. The Workplace Trust Survey (WTS) by Ferres (2002) provides reliable assessment of coworker, supervisor, and organizational trust. By means of a functionally equivalent translation, we developed a German version of the questionnaire (G-WTS) comprising 21 items. A total of 427 employees were surveyed with the G-WTS and questionnaires concerning several work-related attitudes and behaviors and 92 of these completed the survey twice. The hypothesized three-dimensional conceptualization of organizational trust was confirmed by confirmatory factor analysis. The G-WTS showed good internal consistency and retest reliability values. Concerning convergent validity, all of the three G-WTS dimensions positively predicted job satisfaction. In terms of discriminant validity, Coworker Trust enhanced group cohesion; Supervisor Trust fostered innovative behavior, while Organizational Trust was associated with affective commitment. Theoretical and practical contributions as well as opportunities for future research with the G-WTS are discussed.

The article discusses the reasonsfor an expert to participate in legal proceedings. The gnoseological reason for that consists of the bad quality of materials subject to examination that renders the examination either completely impossible or compromises objective, reasoned and reliable assessment of the findings. The procedural reason consists ofa proscription for an expert to collect evidence himself or herself. The author investigates into the ways of how an expert can participate in legal proceedings. If the defense invites an expert to participate in the proceedings, then it is recommended that his or her involvement should be in the presence of attesting witnesses and recorded in the protocol. In the course of the legal proceedings an expert has the following tasks: adding initial data, acquiring new initial data, understanding the situation of the incident, acquiring new objects to be studied, including samples for examination. An expert’s participation in legal proceedings differs from the participation of a specialist or an examination on the scene of the incident. The author describes the tasks that an expert solves in the course of legal proceedings, the peculiarities ofan investigation experiment practices, the selection of samples for an examination, inspection, interrogation.

Challenges of assessment might come up from different reasons or circumstances which generate huge obstacles and dissatisfactions for teachers and students in the same time. Meanwhile, teachers of foreign languages see them as barriers or complications due to an effective and reliable assessment. Firstly, this paper elaborates on theoretical part of assessment, as a crucial tool to measure students’ performance of speaking, as a significant English skill, and then it is presented the elaboration of challenge and its sub-challenges during my work as an English assistant at my tutorial classes on a specific course such as “Integrated English Skill III”, particularly focusing on speaking skill. After it, there is an expansion of others’ research done on this issue, supported by different teaching approaches, and relying on others’ work related to such issue. And at the end of this paper it can be found the summary and recommendations, which wereconducted from the empirical research.

The Embung Bengawan Project in Tarakan City has several jobs requiring heavy equipment including mechanical soil removal activities. Activity of mechanical soil movement is a series in work of loading and transportation equipment. In order to achieve optimal mechanical soil removal targets, it is necessary to know the performance of the machine during the mechanical soil removal process. The optimization of production is the way to obtain production that is in accordance with optimal conditions of mechanical devices. This paper discusses the optimization of dump truck queue time and the number of dump trucks. Performance calculation tool using the method of production capacity of the tool, and calculate the optimal queue using the Queue Model method. Calculation using queuing model method obtained by result of time required by 3 excavator unit and with combined amount of dump truck will give result of cost equal to Rp 48,097,711 / day, and dump truck waiting time in queue to 1 minute. Then the optimal time is obtained by operating 3 units of excavators with a cost difference of Rp 3,572,826 / day from the real condition of the field that operates 2 excavator units

Control Surfaces

Mechanical devices that include home appliances, automobiles, and airplanes are typically driven by electric motors or combustion engines through gearboxes and other linkages. Airplane wings, for example, have hinged control surfaces such as ailerons. Now imagine a wing that has no hinged control surfaces or linkages but that instead bends or warps to assume an appropriate shape, like the wing of a bird. Such a device could be enabled using an electro-active polymer technology based on electronic artificial muscles. Artificial muscles act directly on a structure, like our leg muscles that are attached by tendon to our bones and that through phased contraction enable us to walk. Sensory feedback from our muscles enables proprioceptive control. So, for artificial muscles to be used appropriately we need to pay attention not only to mechanisms for muscle actuation but also to how we can incorporate self-sensing feedback for the control of position.

This article focuses on the practice of machine theater that originated from courtly spectacles in Italy during the Renaissance and developed throughout Western and Central Europe during the seventeenth century. Defined by rapid scene changes and special effects, machine plays reflect the Baroque fascination with both mechanical devices and the law of optics—or scenery perspective—to produce wonder while displaying royal power and prestige. The aim of this article is threefold: to provide an overview of the origins and development of machine theater, to examine the transmission and dissemination of stagecraft knowledge, and to look at the changing nature of machine plays performed by public theater companies, which took advantage of stage machinery innovations to broaden their repertoire, attract a larger audience, and remain competitive.

IntroductionMajor orthopedic surgery, particularly total joint replacement or hip fracture, represents a high risk of future development of postoperative venous thromboembolism and warrants the routine use of prophylaxis with either mechanical devices or pharmacological agents. The aim of prophylaxis is to prevent fatal pulmonary embolism (PE) and the morbidity of deep vein thrombosis (DVT), particularly the development of post-thrombotic syndrome. Patterns of clinical practice, with respect to the prevention of venous thromboembolism and the appropriate use of anticoagulants for the treatment of thrombotic disease, have been strongly influenced by recent consensus conferences.1,2 Rules of evidence for assessing the literature have been applied to all recommendations regarding the prevention and treatment of thrombotic disease. These results were extrapolated using evidence gleaned from major clinical disorders and are based only on nonrandomized clinical trials or case series.1-3 Data from a large number of Level I clinical trials in patients undergoing orthopedic surgery have provided answers to many of the questions regarding prophylaxis of venous thromboembolism. In this review, we will discuss the prevention of venous thromboembolism following orthopedic surgery and discuss some of the controversial issues where further studies are required.

Abstract The identification of gastrointestinal (GI) motility disorders requires the evaluation of regional GI transit, and the development of alternative methodologies in animals has a significant impact on translational approaches. Therefore, the purpose of this study was to validate an easy and low-cost methodology (alternate current biosusceptometry – ACB) for the assessment of regional GI transit in rats through images. Rats were fed a test meal containing magnetic tracer and phenol red, and GI segments (stomach, proximal, medial and distal small intestine, and cecum) were collected to assess tracer’s retention at distinct times after ingestion (0, 60, 120, 240, and 360 min). Images were obtained by scanning the segments, and phenol red concentration was determined by the sample’s absorbance. The temporal retention profile, geometric center, gastric emptying, and cecum arrival were evaluated. The correlation coefficient between methods was 0.802, and the temporal retention of each segment was successfully assessed. GI parameters yielded comparable results between methods, and ACB images presented advantages as the possibility to visualize intrasegmental tracer distribution and the automated scan of the segments. The imaging approach provided a reliable assessment of several parameters simultaneously and may serve as an accurate and sensitive approach for regional GI research in rats.

Point Of Care Ultrasonography

<b><i>Background:</i></b> Lingering congestion portends poor outcomes in patients with heart failure (HF) and is a key target in their management. Studies have shown that physical exam has low yield in this setting and conventional methods for more precise assessment and monitoring of volume status (e.g., body weight, natriuretic peptides, and chest radiography) have significant inherent shortcomings. <b><i>Summary:</i></b> Point of care ultrasonography (POCUS) is a noninvasive versatile bedside diagnostic tool that enhances the sensitivity of conventional physical examination to gauge congestion in these patients. It also aids in monitoring the efficacy of decongestive therapy and bears prognostic significance. In this narrative review, we discuss the role of focused sonographic assessment of the heart, venous system, and extravascular lung water/ascites (i.e., the pump, pipes, and the leaks) in objective assessment of fluid volume status. <b><i>Key Messages:</i></b> Since each of the discussed components of POCUS has its limitations, a combinational ultrasound evaluation guided by the main clinical features would be the key to reliable assessment and effective management of congestion in patients with HF.
