Sensing the Metaverse: The microfoundations of complementor firms' dynamic sensing capabilities in emerging-technology ecosystems

Dynamic capabilities allow firms to adapt to rapidly changing environments, such as digital business ecosystems (DBEs) based on emerging technologies. Here, non-focal firms face specific challenges, since they have little leverage over the ecosystems in which they operate. In the case of the metaverse – which can be conceptualised as a series of emerging-technology-based DBEs – dynamic sensing capabilities (DSCs) are particularly important for grasping this potentially vast albeit vague opportunity.Our explorative study of 14 virtual reality companies operating in Germany operationalises the microfoundations of these DSCs. Based on 25 interviews with commercial and technical top management executives, we introduce taxonomic differentiation and explore the impact of size/resource base and business model/market type (B2B/B2C) on DSCs.We find that productive opportunism and bricolage behaviour allow non-focal firms to navigate the sheer complexity of the environment. Social screening helps to unlock tacit knowledge as do knowledge-creating routines such as technical experimentation and co-creation (with customers, suppliers and even competitors).Furthermore, our findings enlarge the understanding of DBEs as not horizontally competing but as being organised in a downstream–upstream relationship. Moreover, we find that (commercially oriented) opportunity screening is closely and crucially linked with dynamic seizing capabilities (e.g. customer-driven prototyping and business model development).

The Impact of Market and Non-Market-Based Environmental Policy Instruments on Firms’ Sustainable Technological Innovation: Evidence from Chinese Firms

A firm’s sustainable technological innovation (STI) is an important strategy to cope with the global challenges of the climate emergency and resource constraints. To encourage firms to pursue sustainable innovation, the government put its efforts into designing a proper environmental policy (EP). According to Porter’s hypothesis, a well-designed and flexible EP will advance the pace of a firm’s innovation. This paper argues that a flexible EP portfolio combining market and non-market-based EP instruments may affect a firm’s STI. Market-based EP instruments are cost-effective and consistent from a long-term view, whereas non-market-based EP instruments are more forceful and effective in the short term. Hence, these two kinds of EP instruments could complement each other. Furthermore, technical executives in top management teams will moderate the relationships between EP instruments and firms’ STI. Data analysis results of 618 Chinese public firms, who constantly participated in R&D activities during 2015–2019, supported these hypotheses. Contributions to EP and firm innovation theory, as well as suggestions for policymakers and firms’ top management teams, are discussed.

Formula for the success of humor journalism formats on television according to their professional teams

Success on television can be measured according to a series of variables. In this work, a theoretical review was carried out to determine its main factors, complemented with 34 in-depth interviews with the heads of the seven longest-running journalistic humor formats on Spanish television from 1990 to 2015. Owing to their importance in terms of broadcasting and support from society, these enable an evaluation of entertainment as it is linked to information, as both a societal need and technique for escapism, thus depicting the enhanced importance of the television medium in terms of how its content, characters, and structure form part of our collective history. The conclusions have a social character in revealing what the public has consumed, and an economic character, as they decipher what works on television, using a method based on five factors: content, technical execution, awards and reviews, audience, and context. The interviewees provide the keys to the success of the audiovisual cultural industry, characterized herein using 100 categories. For television professionals, success is a utopia that is achieved only by those who combine high-quality content and excellent technical execution, for which they receive awards and strong reviews that reinforce their image with the audience, whose numbers and opinion determine, together with the context, competition, and market conditions, their time on air. Their statements reveal that differentiation, talent, the backing of the network, and creative freedom based on tenacity are fundamental features. Achieving success is a complex task, with a proven formula that does not only represent a limitation but also enables innovative contributions from other genres.

Engineers and Execs Agree Shale Science Projects Are Worth It

_ It was a testimony to the impact science projects have had on the shale sector that kicked off the 15th Annual SPE Hydraulic Fracturing Technology Conference and Exhibition (HFTC) held in the Houston area. When the technical experts and executives gathered, they discussed how, after years of subsurface study, past beliefs have been dispelled and new learnings translated into multimillion- to billion-dollar business decisions. At the conference’s plenary session, attendees learned from Devon Energy about why the oil company has become a vocal champion of refracturing and the influence it had on a recent acquisition that doubled its position in the Eagle Ford Shale. Bakken Shale producer Hess Corp. tied more than a decade of work to its experimental wells that use fractures from other wells to produce oil, as well as its commitment to developing automated fracturing despite facing obstacles in industry collaboration. SM Energy also showcased a double minifrac test as an example of the new experiments guiding its unconventional strategy in the Eagle Ford and Austin Chalk formations found in south Texas. A closer look at what they had to say is here. Betting Big on Refracturing In SPE 212340, Devon offered fresh details on its big refracturing study in the Eagle Ford Shale—one that played into its decision to spend $1.8 billion last year on an acquisition in the south Texas play. It involved two parent wells originally stimulated in 2013 and then refractured in January 2022. As a result, Devon reports the respective estimated ultimate recovery (EUR) from each well soared by 27% and 46%. These are wells that had been producing about 20 to 25 B/D, and according to data shared in the paper, at least one of them topped 1,000 B/D in the weeks following the refracturing. Kourtney Brinkley described the recovery boost as a “significant step change” that helped the company realize a “need to incorporate recompletions into our development plans as we go forward.” The drilling and completions engineer who helped lead the project for Devon reported that the operator’s wider refrac program in the play has seen incremental EUR increases as high as 75% with the average being at around 50%. The figures translate to a rate of return between 97 to 220%, which she said makes them “very economic projects.” The project Brinkley outlined at the conference fell under the US Department of Energy’s (DOE) hydraulic fracturing test site program. With the help of federal funding, Devon was able to deploy an enviable array of diagnostic tools. An observation lateral was drilled to monitor refracturing along with new completions on the pad. About 420 ft of core was taken from the observation well to capture some of the pad’s parent well fracture system. The diagnostic kit included multiple fiber-optic installations, sealed wellbore pressure monitoring, downhole pressure gauges, ultrasonic imaging, and more. With this rare suite of technologies, Devon was able to learn exactly how poor the initial parent completions were while later seeing just how effective its refrac designs ended up being. First came the parent core-through that showed while a hydraulic fracture was present every 10 ft on average, the number of propped fractures represented just 8% of the total found. Ultrasonic imaging aligned, showing initial completion design netted a cluster efficiency rate of just 19%. Post-refrac, that number was increased to over 80%, which implies to Devon that there are a good degree more propped fractures today.

Review of the Literature on Partial Resections of the Gallbladder, 1898-2022: The Outline of the Conception of Subtotal Cholecystectomy and a Suggestion to Use the Terms 'Subtotal Open-Tract Cholecystectomy' and 'Subtotal Closed-Tract Cholecystectomy'.

Current descriptions of the history of subtotal cholecystectomy require more details and accuracy. This study presented a narrative review of the articles on partial resections of the gallbladder published between 1898 and 2022. The Scale for the Assessment of Narrative Review Articles items guided the style and content of this paper. The systematic literature search yielded 165 publications. Of them, 27 were published between 1898 and 1984. The evolution of the partial resections of the gallbladder began in the last decade of the 19th century when Kehr and Mayo performed them. The technique of partial resection of the gallbladder leaving the hepatic wall in situ was well known in the 3rd and 4th decades of the 20th century. In 1931, Estes emphasised the term 'partial cholecystectomy'. In 1947, Morse and Barb introduced the term 'subtotal cholecystectomy'. Madding and Farrow popularised it in 1955-1959. Bornman and Terblanche revitalised it in 1985. This term became dominant in 2014. From a subtotal cholecystectomy technical execution perspective, it is either a single-stage (when it includes only the resectional component) or two-stage (when it also entails closure of the remnant of the gallbladder or cystic duct) operation. Recent papers on classifications of partial resections of the gallbladder indicate the extent of gallbladder resection. Subtotal cholecystectomy is an umbrella term for incomplete cholecystectomies. 'Subtotal open-tract cholecystectomy' and 'subtotal closed-tract cholecystectomy' are terms that characterise the type of completion of subtotal cholecystectomy.

Video-based formative and summative assessment of surgical tasks using deep learning

To ensure satisfactory clinical outcomes, surgical skill assessment must be objective, time-efficient, and preferentially automated—none of which is currently achievable. Video-based assessment (VBA) is being deployed in intraoperative and simulation settings to evaluate technical skill execution. However, VBA is manual, time-intensive, and prone to subjective interpretation and poor inter-rater reliability. Herein, we propose a deep learning (DL) model that can automatically and objectively provide a high-stakes summative assessment of surgical skill execution based on video feeds and low-stakes formative assessment to guide surgical skill acquisition. Formative assessment is generated using heatmaps of visual features that correlate with surgical performance. Hence, the DL model paves the way for the quantitative and reproducible evaluation of surgical tasks from videos with the potential for broad dissemination in surgical training, certification, and credentialing.

Effects of eliminating visual cues on kinetic and kinematic parameters in back tuck somersault: A comparison between artistic gymnasts and parkour athletes

Purpose The aim of this study was to compare the effect of vision (i.e., open and closed eyes) on the kinetic and kinematic parameters of the standing back tuck somersault (SBTS) in artistic gymnasts and parkour athletes. Methods Eleven male parkour athletes (age 22.53 ± 2.36 years; height 1.72 ± 0.08 m; weight 69.58 ± 3.72 kg) and seven male artistic gymnasts (age 21.96 ± 2.64 years; height 1.62 ± 0.02 m; weight 63.54 ± 1.35 kg) participated in this study. Each subject was asked to perform the SBTS in the same condition (i.e., first open-eyes then closed-eyes). 2D kinetic and kinematic analysis was conducted. Results The results showed significant interaction (i.e., vision and sport) obtained at the take-off angle (p < 0.05 and d = 1.992), horizontal displacement (p < 0.05 and d = 1.906) and technical execution (p < 0.05 and d = 1.972). This interaction indicates that when vision is permitted, artistic gymnasts and parkour athletes were similar in all kinetic and kinematic parameters, and technical execution (p > 0.05). However, the elimination of vision during SBTS only affected parkour athletes (i.e., landing angle, ground reaction force, vertical velocity and technical execution, p < 0.05 and d >1.20) while artistic gymnasts remain unchanged. Conclusions We conclude that the specificity of the practice in each of the two sports disciplines influences the kinetic and kinematic control of the SBTS and suggests that with closed-eyes, the integration of afferent information relating to the vestibular and proprioceptive systems is different and specific to each discipline’s goal. Artistic gymnasts seem to be better skilled in the mechanical and technical control of the SBTS than parkour athletes.

The Main Forms of Advanced Training of Soviet Censors in the Second Half of the 1940s (proceeding from the materials of the State Archives of Kirovohrad Oblast)

The article aims to study the main forms of advanced training of Soviet censors in the second half of the 1940s. The scientific novelty is presented by the fact that the problem has not been studied in Ukrainian historiography in such a statement and within such a chronological framework. The research methodology is grounded on a combination of general scientific (analysis, synthesis, and generalization) and specialhistorical (historical-typological, historical-systemic, and historical-genetic) methods. The research is based on the principles of historicism, systematicity and scientific knowledge. It has been found that professional training of censors was carried out directly at the workplace. Several forms of advanced training were applied in parallel, namely: professional training, seminars, meetings of censorship workers (at regional, republican and all-Union levels) and the party education system. The main forms of control over the level of information assimilation by the censors necessary for the implementation of the tasks set before them by the Soviet authorities have been highlighted and considered. In particular, such forms of control included passing technical minimums and execution of training exercises on knowledge of the “List of information prohibited for publication in the open press”. The analysis of the sources proved that the majority of the censorship employees were self-taught, since no educational institution in the country trained specialists for the needs of Soviet censorship. The lack of experience and practical skills of employees of censorship bodies affected the quality of the censorship system work in general. Therefore, the Holovlit of the Ukrainian SSR controlled the professional training of censors constantly. The regime had to spend a lot of time training all new employees and regularly monitor the performance of the tasks assigned to them. The employees of the censorship bodies systematically raised their ideological and political level because they were to become the conductors of the comprehensive ideological control of the Soviet government and interfere in the creative process, professional activity and private life of citizens.

POSSIBILITIES TO OBJECTIFY THE TECHNICAL ELEMENTS OF MARTIAL ARTS - KICKBOXING WITH THE HELP OF KINEMATIC ANALYSIS

Knowing best the Romanian kickboxing trainings level, but also having a good sense of the levels from other martial arts we considered that by using cinematic analyzes through modern technology applicable to motor activities we can objectify the executions of the technical elements from kickboxing in order to have a new approach in terms of evaluating them. For this study, a system of inertial measurement units was used, capturing the movement of the entire human body performing specific kickboxing techniques, each sensor being composed of 3D gyroscopes, accelerometers and 3D magnetometers, small in size along with advanced algorithms and biomechanical models. The system used in the studio was MVN Awinda, the version based on sensor straps, which transmits data to the PC / laptop wirelessly. There are 17 motion tracking sensors attached to the body in order to reconstruct 3D the human movement. Through this study we wished to link the methodical indications from the specialty literature and concrete technical executions, proving that the biomechanics elements can be objectively measured. Some of the most used striking techniques were chosen, performed by high level Romanian kickboxers and monitored with said equipment in order to objectify them and extract information useful for conducting trainings. We measured key kinematic parameters and extracted precise data about punching velocity, hips and shoulder rotations and angle varations. Likewise, the research is meant to be a step for future studies, even in other sports disciplines and to encourage the use of technology in sports training.

Ex Vivo Evaluation of a Pressure-Sensitive Device to Aid Big Bubble Intrastromal Dissection in Deep Anterior Lamellar Keratoplasty.

To develop and perform ex vivo testing for a device designed for semiquantitative determination of intracorneal dissection depth during big bubble (BB) deep anterior lamellar keratoplasty. A prototype device connected to a syringe and cannula was designed to determine depth of intrastromal placement based on air rebound pressure emitted by a software controlled generator. Ex vivo testing of the device was conducted on human corneas mounted on an artificial anterior chamber in three experiments: (1) cannula purposely introduced at different depths measured with anterior segment optical coherence tomography, (2) cannula introduced as per the BB technique, and (3) simulation of the BB technique guided by the device. A positive pressure differential and successful BB were observed only when the cannula was positioned within 150 microns from the endothelial plane. In all successful BB cases (21/40), a repeatable increase in tissue rebound pressure was detected, which was not recorded in unsuccessful cases. The device was able to signal to the surgeon correct placement of the cannula (successful BB) in 16 of 17 cases and incorrect placement of the cannula (unsuccessful BB) in 8 of 8 cases (94.1% sensitivity, 100% specificity). In our ex vivo model, this novel medical device could reliably signal cannula positioning in the deep stroma for effective pneumatic dissection and possibly aid technical execution of BB deep anterior lamellar keratoplasty. A medical device that standardizes big bubble deep anterior lamellar keratoplasty could increase the overall success rate of the surgical procedure and aid popularization of deep anterior lamellar keratoplasty.

Based on the results of the evaluation, it was found that 95% of respondents were very satisfied in terms of system usability and were greatly helped by the operational side of the system in completing their work.

Execution of plies – basis of classical dance technique

We rest our endeavour on the fact that the correct technical execution of classical dance movements may lead to the development of specific motor skills and their accurate performance, hence leading to higher precision in movement. This will result in increased body stability when at rest and in motion, increased number of pirouette turns and in higher joint range of motion. This research aims at determining the interindividual differences occurring in similar training conditions in children learning classical dance techniques, and the way in which the proper acquisition of movement mechanisms helps improve the execution technique. Higher mobility of lower limb joints combined with the development of muscular strength in the lower body may lead to accurately performing the classical dance technical elements. We measure the subjects’ mobility of the lower limbs and the maximum amount of force generated by their lower body muscles during the first year of study. At the end of the year, after developing the basic skills, the subjects undergo retesting. Proper training at the appropriate time is an important indicator of measuring the accuracy of performing the motor skills developed over the years, thus contributing to a long and injury-free career of the dancers.

No association between dynamic trunk flexion strength and throwing velocity in elite women handball players

BACKGROUND: The relationship between strength and throwing velocity is much investigated in handball, but core strength is largely ignored. Only four studies have investigated the effect of core training on handball throwing velocity, reporting conflicting results in amateur players. However, lack of specificity and deficient technical execution of throwing in amateurs can obscure the results. OBJECTIVE: To examine the direct association between trunk flexion strength and throwing velocity in elite handball players, using women as a model. METHODS: Sixteen women players from an elite-level Norwegian handball team participated in the study. Strength in trunk flexion, shoulder extension, internal shoulder rotation, and forearm pronation was assessed using isokinetic dynamometer measurements (peak moment, total work, angular impulse). Throwing velocity in both the standing throw with run-up and the jump throw was determined from motion capture measurements. To account for arm strength, the association between trunk flexion strength and throwing velocity was examined using partial correlation analyses. RESULTS: No significant association was found between any measure of trunk flexion strength and throwing velocity for either throwing technique (explained variance ⩽ 13.7%). CONCLUSIONS: The results indicate that isolated, dynamic trunk flexion strength is not a differentiating factor for handball throwing velocity in elite women players.

Analysis of Game Actions and Performance in Young Soccer Players: A Study Using Sequential Analysis

The objective of this research is to analyze the performance of actions in a reduced game situation in a sample of young soccer players. This is a game format in which possession of the ball has to be maintained. The sample consisted of 85 young players aged between 12 and 16 years, observing a total of 58 reduced games and using an analysis instrument called the Game Performance Assessment Instrument (GPAI). The essential data quality analyses are carried out, including the use of correlation indexes, Cohen’s Kappa and the Phi index for intra- and inter-observer reliability. Generalizability and invariance analyses are also performed to estimate the reliability, validity and precision of the numerical structure and its generalizability to other samples or populations with similar distributions. An observational design of nomothetic, punctual and multidimensional types is used, and subsequently, a sequential analysis of the game actions is carried out from the observations. The results show significant relationships between decision-making behaviors (adequate and inadequate) and technical execution behaviors (adequate and inadequate). The findings have highlighted a clear relationship of interdependence between technical execution and decision making. This information is very useful for the design and planning of training oriented to the optimization of sport performance in soccer.

Keyhole Approaches Applied to Clipping of Acutely Ruptured Intracerebral Aneurysms—A Technical Note and Case Series

Evolution of keyhole techniques in aneurysm surgery allows for definitive surgical management of aneurysmal pathology with little disruption of normal surrounding tissue. While experienced vascular neurosurgeons are increasingly applying keyhole techniques to unruptured aneurysms, experience with ruptured aneurysms is limited. We sought to explore technical nuances and present operative outcomes for our series of 40 consecutive patients presenting with ruptured intracerebral aneurysms treated with surgical clipping via a keyhole approach. This study is a consecutive, single-surgeon, single-center retrospective case series of aneurysms clipped with keyhole approaches at Helen Joseph Hospital in Johannesburg, South Africa. Patients presenting with subarachnoid hemorrhage were worked up exclusively with computed tomography. On the basis of vessel location and unique anatomic features, aneurysms were clipped through one of these approaches: minipterional, supraorbital, or keyhole interhemispheric. Operative details were assessed on retrospective file review, and patient outcomes were assessed on clinic follow-up. A minipterional approach was used for 55% of cases, the supraorbital approach in 30% of cases, and the mini-interhemispheric approach in 15% of cases. The intraoperative aneurysm rupture rate was 26.2%. Complete aneurysm occlusion was achieved in 97.4% with none of the 40 cases requiring conversion of a keyhole to a larger craniotomy. A good outcome was achieved for 72.5% of patients (modified Rankin Scale score ≤2). For patients presenting with World Federation of Neurological Surgeons grade I to III subarachnoid hemorrhage, 92.9% achieved a good outcome. The present series supports the concept that sound technical execution of keyhole approaches, even in the setting of acutely ruptured cerebral aneurysms, is a viable option for clipping of intracranial aneurysms.

Integrating audio-video technology in teaching children the long jump and oina ball throw

The purpose of the research was to highlight the effect produced by audio-video technology on the training process conducted in two athletics events by using rating scales for technical execution, which were completed by the coach after watching the videos recorded for each participant. At the initial and final assessments, the investigated athletes performed two tests, namely the running long jump and long throw of the oina ball (140 g), which were video-recorded to measure their performance in meters. The videos recorded in the two testing phases and the two rating scales were used as tools for the assessment of technical execution. The study participants were 12 girls aged between 9 and 10 years. The training programme was implemented from September 2021 to July 2022, involved three training lessons per week and included daily 10-minute viewings of technical execution. The results of the athletes participating in the research highlighted progress in both the technical execution at all moments established by the rating scales and the performance achieved in the two tests. There was a significant difference with a large effect size between the initial and final assessments of the running long jump and long throw of the oina ball (r = 0.88).

Laterality assessment in martial artists through kinematic analysis of striking techniques

The purpose of this study was to objectively measure and highlight laterality differences in striking techniques between elite martial artists and to compare the results achieved by each athlete. The research hypothesis is that the kinematic analysis of both fighting stances (dominant and non-dominant sides) can reveal laterality differences for each athlete. We used an inertial measurement unit system based on 17 motion trackers consisting of 3D gyroscopes, 3D accelerometers and 3D magnetometers, namely the Xsens MVN Awinda system. We collected data on the striking techniques of 8 elite martial artists. The kinematic parameters were calculated and analysed for some of the most commonly used techniques in martial arts, more specifically, straight and roundhouse punches. In order to obtain information about the laterality levels of the monitored athletes, we compared the values of these parameters for technical execution on the dominant and non-dominant sides and highlighted significant differences through the non-parametric Wilcoxon Signed-Ranks Test of significance. To facilitate comparisons between athletes in terms of laterality, we designed an original rating scale and created diagrams based on their scores. The assessments carried out will contribute to both the management and individualisation of training and the choice of combat tactics in a much more informed way.

Implications of the choice of distance-based measures in assessing and investigating tumble turn performance.

Although the tumble turn in swimming has been studied extensively, no consensus exists about which measure is best suited to capture its performance. The aim of this study was to better understand the implications of choosing a particular distance-based performance measure for assessing and investigating tumble turn performance in freestyle swimming. To this end, a large set of retrospective turn data consisting of 2,813 turns performed by 160 swimmers was analyzed statistically in three steps. First, a mixed-effects model was derived for the entire data set, which showed that both performance level and sex had clear effects on the distance-based performance measures and performance determining variables studied in the literature. Second, repeated measures correlations were calculated for the entire data set and four performance level- and sex-based subgroups to determine the level of association between the performance measures. This analysis revealed that the performance measures were strongly correlated (r > 0.84 and p < 0.05 for all possible pairs), largely independent of performance level and sex. This finding implies that the choice of performance measure is not very critical when one is interested solely in the overall performance. In the third and last step, mixed-effects models were derived for the performance measures of interest to establish the importance of different turn-related actions for each measure, again for both the entire data set and the four subgroups separately. The results of this analysis revealed that performance measures with short(er) distances are more sensitive to changes in the adaptation time and reflect the wall contact time better than performance measures with long(er) distances, which in contrast are more useful if the focus is on the approach speed prior to the turn. In this final analysis, various effects of performance level and sex were found on the technical execution of the tumble turn.

New methods of sectional studies of the human pelvis and perineum

BACKGROUND: Currently, the issue of sectional studies in developing methods for expert assessment of pelvic organs and the perineum in road accidents, falls from a height, perineal intentional injury with any objects, and sexual crimes remain relevant.&#x0D; AIM: To develop standardized sectional methods for pelvic and perineal forensic examinations.&#x0D; MATERIALS AND METHODS: This study included 10 corpses of elderly and senile persons who are subject to forensic medical examination, no later than 12 h after death confirmation. We introduced three new methods for forensic studies of the pelvis and the perineum: the study of the human perineal organ complex (two males and one female); the method of perineal muscle isolation (two females and two males); the method of access the perineal center and associated muscles (two females and one male).&#x0D; RESULTS: Three new methods of pelvic and perineal forensic examination were developed and patented. The method of human perineal organ complex isolation allows expert studies to sample the organ complex of the pelvis and the perineal region in the corpse while preserving the topographic and anatomical relationships. This method is of particular importance for expert studies of corpses with extra body weight. The method of perineal muscle isolation was intended for visual access to examine the pelvic diaphragm muscles, intermuscular spaces, and/or sample tissue fragments for histological examination. The method to access the perineal center and associated muscles are intended for urological and obstetric study of the perineum and pelvic floor muscles.&#x0D; CONCLUSION: The proposed methods are recommended for sectional forensic studies in cases of suspicion of injuries and pathological processes of various genesis in the pelvic region and the perineum. These methods are simple in technical execution, as well as for expert studies of this area in corpses, with extra body weight, and do not require complex skills and special equipment.
