Abstract This paper is concerned with the evaluation and tabulation of certain integrals of the type (* 00 I(p, v; A) = J J fa t) ) e~cttxdt. In part I of this paper, a formula is derived for the integrals in terms of an integral of a hypergeometric function. This new integral is evaluated in the particular cases which are of most frequent use in mathematical physics. By means of these results, approximate expansions are obtained for cases in which the ratio b/a is small or in which b~a and is small. In part II, recurrence relations are developed between integrals with integral values of the parameters pt, v and A. Tables are given by means of which 7(0, 0; 1), 7(0, 1; 1), 7(1, 0; 1), 7(1,1; 1), 7(0, 0 ;0), 7(1, 0;'0), 7(0, 1; 0), 7(1, 1; 0), 7(0,1; - 1 ), 7(1,0; - 1 ) and 7(1,1; - 1 ) may be evaluated for 0 < b/a ^ 2, 0 ^ c/a ^ 2.

Tendon disorders are frequent and are responsible for substantial morbidity both in sports and in the workplace. Tendinopathy, as opposed to tendinitis or tendinosis, is the best generic descriptive term for the clinical conditions in and around tendons arising from overuse. Tendinopathy is a difficult problem requiring lengthy management, and patients often respond poorly to treatment. Preexisting degeneration has been implicated as a risk factor for acute tendon rupture. Several physical modalities have been developed to treat tendinopathy. There is limited and mixed high-level evidence to support the, albeit common, clinical use of these modalities. Further research and scientific evaluation are required before biological solutions become realistic options.

This article explores the metaphor of performance to investigate how tourism can be conceived as a set of activities, imbricated with the everyday, whereby conventions are reinforced and broken. By looking at the contexts in which tourism is regulated, directed and choreographed or, alternatively, is a realm of improvisation and contestation, I will consider the constraints and opportunities which shape the ways in which tourist space (here considered as ‘stages’) and performance are reproduced, challenged, transformed and bypassed. A range of examples will be used to exemplify the ways in which tourism is staged and performed. I will also focus on how the global proliferation of tourist practices and attractions acts to theme tourist space in highly commodified ways and simultaneously decentre normative modes of performing tourism.

This study investigated predictors of attachment security in a play context using a sample of 71 mothers and their 6-month-old infants. We sought to rethink the concept of maternal sensitivity by focusing on mothers' ability accurately to read the mental states governing infant behaviour. Five categories were devised to assess this ability, four of which were dependent on maternal responses to infant behaviours, such as object-directed activity. The fifth, mothers' Appropriate minded-related comments, assessed individual differences in mothers' proclivity to comment appropriately on their infants' mental states and processes. Higher scores in this fifth category related to a secure attachment relationship at 12 months. Maternal sensitivity and Appropriate mind-related comments were independent predictors of attachment security at 12 months, respectively accounting for 6.5% and 12.7% of its variance. We suggest that these findings are in line with current theorising on internal working models of attachment, and may help to explain security-related differences in mentalising abilities.

This study investigated relations between social interaction during infancy and children's subsequent theory of mind (ToM). Infant-mother pairs (N = 57) were observed in a free-play context at 6 months. Interactions were coded for (a) mothers' use of mental state language that commented appropriately on the infants' mental states, and (b) mothers' use of mental state language that did not appropriately reflect their infants' minds. A third variable was (c) security of attachment, which was assessed using the Strange Situation procedure at 12 months. Performance on a battery of ToM tasks at 45 and 48 months was positively correlated with (a), but was not related to (b) or (c). A regression analysis showed that mothers' use of appropriate mental state comments independently predicted overall ToM performance, accounting for 11% of the variance. Children's verbal ability was the only other independent predictor of ToM performance, accounting for 16% of the variance. These findings represent the earliest known social predictor of individual differences in ToM.

Semiotics, the science of signs, has long been recognised as an important discipline for understanding information and communications. Moreover it has found wide application in other areas of computer science, as it offers an effective insight into organisations and the computer systems that support them. An organisation may be viewed as a system of information and communication in which human actors, with the assistance of information technology, are able to process, represent, store and consume information. Computer systems that fit into an organisation and that support and enhance its performance and competitiveness, can be better delivered if semiotic principles are understood and applied. In this book, first published in 2000, semiotic methods are introduced and illustrated through three major case studies, which demonstrate how information systems can be developed to meet business requirements and support business objectives. It will appeal to academics, systems developers and analysts.

The upcoming fifth generation (5G) of wireless networks is expected to lay a foundation of intelligent networks with the provision of some isolated artificial intelligence (AI) operations. However, fully intelligent network orchestration and management for providing innovative services will only be realized in Beyond 5G (B5G) networks. To this end, we envisage that the sixth generation (6G) of wireless networks will be driven by on-demand self-reconfiguration to ensure a many-fold increase in the network performance and service types. The increasingly stringent performance requirements of emerging networks may finally trigger the deployment of some interesting new technologies, such as large intelligent surfaces, electromagnetic-orbital angular momentum, visible light communications, and cell-free communications, to name a few. Our vision for 6G is a massively connected complex network capable of rapidly responding to the users' service calls through real-time learning of the network state as described by the network edge (e.g., base-station locations and cache contents), air interface (e.g., radio spectrum and propagation channel), and the user-side (e.g., battery-life and locations). The multi-state, multi-dimensional nature of the network state, requiring the real-time knowledge, can be viewed as a quantum uncertainty problem. In this regard, the emerging paradigms of machine learning (ML), quantum computing (QC), and quantum ML (QML) and their synergies with communication networks can be considered as core 6G enablers. Considering these potentials, starting with the 5G target services and enabling technologies, we provide a comprehensive review of the related state of the art in the domains of ML (including deep learning), QC, and QML and identify their potential benefits, issues, and use cases for their applications in the B5G networks. Subsequently, we propose a novel QC-assisted and QML-based framework for 6G communication networks while articulating its challenges and potential enabling technologies at the network infrastructure, network edge, air interface, and user end. Finally, some promising future research directions for the quantum- and QML-assisted B5G networks are identified and discussed.

OBJECTIVE: This systematic review and meta-analysis examined the strength of association between rheumatoid arthritis and depression. In addition, we investigated the extent to which sociodemographic characteristics, level of pain, and method of assessing depression might affect the degree of depression. METHODS: CD-ROM databases and bibliographies were searched to identify all studies comparing depression in patients with rheumatoid arthritis and control subjects using standardized assessments. Effect sizes (Pearson's r) and probabilities were combined across studies. We examined the extent to which the association between rheumatoid arthritis and depression could be attributed to level of pain (using contrasts), sociodemographic differences between groups (combining methodologically restricted studies), and methods of assessing depression (examining heterogeneity across studies). RESULTS: Twelve independent studies comparing depression in patients with rheumatoid arthritis with depression in healthy control subjects were found. Effect sizes for depression were small to moderate (r =.21, p <.0001; heterogeneous). This effect was not reduced in studies controlling for sociodemographic characteristics (r =.27, p <.0001). The effect sizes did vary in a linear manner in proportion to the effect size for pain (z = 2.67, p =.0064). The effect sizes produced by different measures of depression were heterogeneous (chi(2) for Fisher's Z = 24.6, p =.0002), with the Hospital Anxiety and Depression Scale giving effect sizes most dissimilar to those of other measures. CONCLUSIONS: Depression is more common in patients with rheumatoid arthritis than in healthy individuals. This difference is not due to sociodemographic differences between groups, but it may be attributable, in part, to the levels of pain experienced. Variation in the methods of assessing depression partly accounts for the differences among studies examining the levels of depression in patients with rheumatoid arthritis.

This article provides population norms for the Short Form Perceived Stress Scale (PSS-4) and investigates the relationship between PSS-4 scores and sociodemographic variables. The PSS-4 was administered to an English sample (n = 1568) and was found to have acceptable psychometric properties. Sociodemographic variables explained 19.5% of variance in PSS-4 scores, and mean PSS-4 scores were significantly different from the mean scores reported in Cohen and Williamson's original study. Greater levels of perceived health status, greater levels of social support, being male and being older were predictive of lower PSS-4 scores. Norm values for interpreting PSS-4 scores are presented.

Advances in information and signal processing technologies have a significant impact on autonomous driving (AD), improving driving safety while minimizing the efforts of human drivers with the help of advanced artificial intelligence (AI) techniques. Recently, deep learning (DL) approaches have solved several real-world problems of complex nature. However, their strengths in terms of control processes for AD have not been deeply investigated and highlighted yet. This survey highlights the power of DL architectures in terms of reliability and efficient real-time performance and overviews state-of-the-art strategies for safe AD, with their major achievements and limitations. Furthermore, it covers major embodiments of DL along the AD pipeline including measurement, analysis, and execution, with a focus on road, lane, vehicle, pedestrian, drowsiness detection, collision avoidance, and traffic sign detection through sensing and vision-based DL methods. In addition, we discuss on the performance of several reviewed methods by using different evaluation metrics, with critics on their pros and cons. Finally, this survey highlights the current issues of safe DL-based AD with a prospect of recommendations for future research, rounding up a reference material for newcomers and researchers willing to join this vibrant area of Intelligent Transportation Systems.

High-speed actions are known to impact soccer performance and can be categorized into actions requiring maximal speed, acceleration, or agility. Contradictory findings have been reported as to the extent of the relationship between the different speed components. This study comprised 106 professional soccer players who were assessed for 10-m sprint (acceleration), flying 20-m sprint (maximum speed), and zigzag agility performance. Although performances in the three tests were all significantly correlated (p < 0.0005), coefficients of determination (r(2)) between the tests were just 39, 12, and 21% for acceleration and maximum speed, acceleration and agility, and maximum speed and agility, respectively. Based on the low coefficients of determination, it was concluded that acceleration, maximum speed, and agility are specific qualities and relatively unrelated to one another. The findings suggest that specific testing and training procedures for each speed component should be utilized when working with elite players.

A study by a ITiCSE 2001 working group ("the McCracken Group") established that many students do not know how to program at the conclusion of their introductory courses. A popular explanation for this incapacity is that the students lack the ability to problem-solve. That is, they lack the ability to take a problem description, decompose it into sub-problems and implement them, then assemble the pieces into a complete solution. An alternative explanation is that many students have a fragile grasp of both basic programming principles and the ability to systematically carry out routine programming tasks, such as tracing (or "desk checking") through code. This ITiCSE 2004 working group studied the alternative explanation, by testing students from seven countries, in two ways. First, students were tested on their ability to predict the outcome of executing a short piece of code. Second, students were tested on their ability, when given the desired function of short piece of near-complete code, to select the correct completion of the code from a small set of possibilities. Many students were weak at these tasks, especially the latter task, suggesting that such students have a fragile grasp of skills that are a prerequisite for problem-solving.

This paper uses elements of Weberian and Foucauldian social theory to speculate on the consequences of recent higher education change in the UK. We argue that changes in the political, institutional and funding environment have produced forms of HE organization that increase the power of management and diminish the autonomy of professional academics. These new forms of organization, which are increasingly bureaucratic and utilize sophisticated systems of surveillance, will make academics increasingly instrumental in their attitudes and behaviour. We conclude that the rationalization of HE should be resisted, but that nostalgia for a previous order should not be part of that resistance. `Mass' higher education organizations are not simply good or bad, but their rationale and consequences need to be clearly thought through if their negative aspects are to be addressed.

Plastic waste is a distinctive indicator of the world-wide impact of anthropogenic activities. Both macro- and micro-plastics are found in the ocean, but as yet little is known about their ultimate fate and their impact on marine ecosystems. In this study we present the first evidence that microplastics are already becoming integrated into deep-water organisms. By examining organisms that live on the deep-sea floor we show that plastic microfibres are ingested and internalised by members of at least three major phyla with different feeding mechanisms. These results demonstrate that, despite its remote location, the deep sea and its fragile habitats are already being exposed to human waste to the extent that diverse organisms are ingesting microplastics.

The objective of the study was to examine the 1-year cumulative incidence of episodic neck pain and to explore its associations with individual risk factors, including a history of previous neck injury. A baseline cross-sectional survey of an adult general population sample made up of all 7669 adults aged 18-75 years, registered with two family practices in South Manchester, United Kingdom, identified the study population of adults with no current neck pain. This study population was surveyed again 12 months later to identify all those who had experienced neck pain during the follow-up period. At follow-up, cumulative 1-year episode incidence of neck pain was estimated at 17.9% (95% confidence interval 16.0-19.7%). Incidence was independent of age, but was more common in women. A history of previous neck injury at baseline was a significant risk factor for subsequent neck pain in the follow-up year (risk ratio 1.7, 95% confidence interval 1.2-2.5), independent of gender and psychological status. Other independent baseline risk factors for subsequent neck pain included number of children, poor self-assessed health, poor psychological status and a past history of low back pain. We have carried out a prospective study in a general population sample and demonstrated that established risk factors for chronic pain predict future episodes of neck pain, and shown that in addition a history of neck injury is an independent and distinct risk factor. This finding may have major public health and medicolegal implications.

In order to determine whether acromegaly is still associated with increased mortality, a hospital case note review of all patients with acromegaly followed up in Stoke-on-Trent since 1967 was carried out. Of 79 subjects identified, 51 are alive and being monitored and 28 have died. Mortality was compared to the general population by life table analysis. Secretion of growth hormone was assessed and compared in dead and alive patients. The effect of diabetes, hypertension, and growth hormone secretion on long-term outcome was assessed. Acromegaly is still associated with increased mortality, with an overall ratio of observed to expected deaths equal to 2.68 (95% C.I. 1.8-3.9; p < 0.001), but the survival of 31 (39%) patients whose growth hormone level had been reduced to below 5 mU/l was equal to that of the general population (O/E = 1.42; 95% C.I. 0.46-3.31: p > 0.05). The dead patients had had significantly higher growth hormone levels than those still alive, but mortality did not appear to be influenced by diabetes or hypertension. The cause of death was vascular in 57% of cases. Growth hormone hypersecretion is still associated with excess mortality in acromegaly. The present study suggests that the therapeutic objective should be to lower average daytime growth hormone levels to less than 5 mU/l. There is need for a large study to compare different modes of treatment in terms of their effect on growth hormone secretion and on long-term outcome.

The construct validity of maternal mind-mindedness (MM) was investigated in the context of its relations with children's later understanding of mind. MM measures were obtained from infant-mother (N = 52) interactions at 6 months, and from maternal interviews at 48 months. Children's understanding of mind was assessed using theory of mind (ToM) tasks at 45 and 48 months, and a stream of consciousness (SoC) task at 55 months. One of the early MM measures--mothers' appropriate mind-related comments--was a positive independent predictor of: (a) MM at 48 months, and (b) ToM and SoC performance at 45 to 55 months. Path analyses suggested direct links between mothers' use of appropriate mind-related comments and children's later understanding of mind.

Abstract Meta‐regression analysis (MRA) can provide objective and comprehensive summaries of economics research. Their use has grown rapidly over the last few decades. To improve transparency and to raise the quality of MRA, the meta‐analysis of economics research‐network (MAER‐Net) has created the below reporting guidelines. Future meta‐analyses in economics will be expected to follow these guidelines or give valid reasons why a meta‐analysis must deviate from them.

Abstract The current research tested if explicit anti‐conspiracy arguments could be an effective method of addressing the potentially harmful effects of anti‐vaccine conspiracy theories. In two studies, participants were presented with anti‐conspiracy arguments either before, or after reading arguments in favor of popular conspiracy theories concerning vaccination. In both studies, anti‐conspiracy arguments increased intentions to vaccinate a fictional child but only when presented prior to conspiracy theories. This effect was mediated by belief in anti‐vaccine conspiracy theories and the perception that vaccines are dangerous. These findings suggest that people can be inoculated against the potentially harmful effects of anti‐vaccine conspiracy theories, but that once they are established, the conspiracy theories may be difficult to correct.
