Cycling Power Profile Characteristics of National-Level Junior Triathletes

Stevens, CJ, Bennett, KJM, Novak, AR, Kittel, AB, and Dascombe, BJ. Cycling power profile characteristics of national-level junior triathletes. J Strength Cond Res 33(1): 197-202, 2019-With the draft-legal rule recently introduced to junior triathlon competition, it has become difficult to assess cycling performance through race results. Therefore, this study assessed the cycling power profile characteristics of national-level junior triathletes to assist with physical assessment and program design. Thirteen male (17.0 ± 1.0 years) and 11 female (17.2 ± 1.3 years) national-level junior triathletes completed a cycling power profile that consisted of maximal intervals that lasted 6, 15, 30, 60, 240, and 600 seconds in duration. Each power profile was completed on a LeMond ergometer using the subject's own bicycle, with power output and cadence recorded for all intervals. Mean power output values for males (783 ± 134, 768 ± 118, 609 ± 101, 470 ± 65, 323 ± 38, and 287 ± 34 W) were significantly (p ≤ 0.05) higher than those for females (554 ± 92, 510 ± 89, 437 ± 75, 349 ± 56, 248 ± 39, and 214 ± 37 W) across all intervals, respectively. Peak power output values for males across the 6- and 15-second intervals (1,011 ± 178 and 962 ± 170 W) were also significantly higher than those for females (674 ± 116 and 624 ± 114 W), respectively (p ≤ 0.05). Developing junior triathletes should aim to increase their capacity across the power profile above the mean values listed. Athletes should further aim to have power outputs equal to that of the best performers and beyond to ensure that they can meet the demands of any competition situation.

2298 Central autonomic network dysfunction implicated in alcohol-related intimate partner violence

OBJECTIVES/SPECIFIC AIMS: Most incidents of partner violence occur when one or both partners have been drinking, however, the mechanism through which this association exists is unclear. The neural circuits that support self-regulation of emotion and social behavior, as well as autonomic influences on the heart, are co-localized in the brain and represent an integrated bidirectional regulatory system. These physiological regulatory processes are mediated by a neural substrate known as the central autonomic network which includes the peripheral autonomic nervous system. The central autonomic network modulates biobehavioral resources in emotion by flexibly responding to physiological arousal in response to changing situational demands, and serves a fundamental role in emotion regulation and goal-directed motor behavior, and this circuit can be indexed with heart rate variability (HRV). METHODS/STUDY POPULATION: In total, 17 distressed violent (DV) partners (11 females, 6 males) were matched to a sample of distressed nonviolent (DNV) partners (7 female, 6 males) were matched on age, sex, and relationship satisfaction and participated in a placebo-controlled alcohol administration study with an emotion-regulation task during which electroencephalography, HRV, and galvanic skin response (GSR) measures were collected. In the alcohol condition, participants were administered a mixture of 100 proof vodka and cranberry juice calculated to raise their blood alcohol concentration to 0.08%. In the placebo condition, participants consumed a volume of juice equivalent to that consumed in the alcohol condition, but without alcohol. Alcohol and placebo conditions were counter-balanced across participants as were the presentation the blocks of evocative and neutral partner stimuli and emotion-regulation condition (watch vs. do not react). RESULTS/ANTICIPATED RESULTS: Results show that DV partners show greater cortical arousal than DNV partners on measures event-related spectral perturbations, which are mean log event-loced deviations from baseline-mean power at each frequency of the electroencephalography power spectra, when intoxicated and viewing evocative partner stimuli in the “do not react” emotion regulation condition. Results also show a statistically significant 2 (alcohol vs. placebo)×2 (watch vs. do not react)×2 (DV partners vs. DNV partners) interaction of the respiratory sinus arrhythmia measure of HRV when viewing evocative partner behavior (F=7.102, p=0.019, partial η2=0.353). Findings indicate that DV partners have lower HRV than DNV partners across conditions, but particularly when acutely intoxicated and trying not to react to their partners’ evocative behavior. Similarly, results also show a statistically significantly 2 (alcohol vs. placebo)×2 (watch vs. do not react)×2 (DV partners vs. DNV partners) interaction on GSR (F=71.452, p=0.000, partial η2=0.749). GSR findings indicate that DV partners also have lower GSR when acutely intoxicated and trying not to react to their partners’ evocative behavior. DISCUSSION/SIGNIFICANCE OF IMPACT: These results suggest that increases in intimate partner violence under acute alcohol intoxication may be the result of dysfunction of the central autonomic network, especially when DV partners are trying to suppress a behavioral response to their partners’ evocative behavior in conflict. The neurophysiological patterns evidenced by DV partners is consistent with a state of vigilance to threat, and reduced ability inhibit prepotent, but inappropriate responses. They also suggest that HRV may be an important target for intervention with partner with a history of intimate partner violence. One method may be heart rate variability biofeedback which has been shown to increase parasympathetic nervous system functioning, autonomic stability, and emotion regulation.

When does performance management foster team effectiveness? A mixed‐method field study on the influence of environmental extremity

SummaryOrganizations operating in extreme environments rely on teams to tackle the highly demanding and complex situations. This study aims to provide new insights into the management of such teams by exploring the influence of environmental extremity on the relationship between performance management and team effectiveness. Mixed‐method and multilevel analyses of police teams working in different levels of environmental extremity suggest that environmental extremity moderates the relationship between performance management features and team effectiveness. Both the vertical alignment of performance management and constructive feedback have a positive effect on team effectiveness. However, these positive effects are constrained in teams working in heightened levels of environmental extremity. The effects of performance management consistency and two‐way communication on team effectiveness are more nuanced and dependent on environmental extremity. When teams operate in heightened levels of environmental extremity, both features are positively related to team effectiveness. When teams operate in lower levels of environmental extremity, performance management consistency is not significantly related to team effectiveness and two‐way communication is negatively related to team effectiveness. These results provide a nuanced understanding of how performance management engenders team effectiveness in extreme environments.

Uncovering expected teaching actions in attention-demanding teaching situations

During the teaching process, a multitude of problems arise in establishing and maintaining relationships with students. The need to fully understand teaching requires more detailed and explicit knowledge regarding the ways teachers perceive and think about their classroom actions. This collective case study focuses on investigating teachers’ expectations of their teaching actions as well as the varying levels of intensity within differential teaching investments in expected teaching actions. Structured interviews were conducted with 10 primary school teachers, and the data were analysed using a primarily inductive coding scheme. The results provide a detailed exploration of two approaches, the interactional approach and the instructional approach, and their respective teaching methods. In both approaches, teachers’ investments in expected teaching actions illustrate a continuum of low and high intensities. The results may assist in gaining a better understanding of the situational demands of teaching. By being more conscious of their teaching actions, teachers can develop their pedagogical skills more deliberately.

Resilience through interpretive practice – A study of robotic surgery

The paper provides an ethnographic description of robotic surgery, along with task and work-domain analyses of it, with focus on surgeons’ adaptation to situational demands. Thereby, the study conducted ties in with the discussions on resilience and interpretive practice, theoretical approaches that consider human capability and improvisation in activity as sources of safety. The study methods include observations of operations, video analyses, interviews and self-confrontation sessions (i.e., surgeons commenting on video samples of their own work). The results are summarised in a conceptual model encompassing the basic elements that enable robotic surgery as an activity: manual, perceptual, social, and cognitive aspects are covered at three hierarchical levels, from strategies and planning to routinised techniques. Uncertainties and complexities that render adaptation challenging are elaborated upon. Robotic surgery could be considered a complex form of navigation since where anticipatory interaction with the environment is needed – the surgeon creates the landscape where the operation takes place, and tissues are identified and separated by palpation, albeit without tactile feedback, and with careful consideration of the patient’s health. In this challenging environment conflictual aims are to be addressed: minimal damage should be induced while one removes the cancer. The findings suggest that resilient activity is manifested in an interpretive human–environment connection wherein appropriate generic principles and aims guide more specific work actions; a hierarchy in adaptation to situational demands can therefore be identified as the specific actions, usually based on relatively fixed routines, vary and adapt in line with higher-level principles.

Association Between Work-Related Stress and Coronary Heart Disease: A Review of Prospective Studies Through the Job Strain, Effort-Reward Balance, and Organizational Justice Models.

Work‐related stress is an example of a psychosocial risk factor that has become of interest in today's ever‐demanding, fast‐paced, and globalized society, although its link to adverse health and in particular coronary heart disease (CHD) is incompletely understood. In this review, we will

The use and evolution of design methods in professional design practice

Through interviews, observation and document reviews, we investigated how design methods are applied and developed in a Norwegian design company with a focus on safety-critical systems. Our analysis revealed that design methods are used and developed through pragmatic, cyclic evolutions which vary across projects. Particular methods are adapted to fit situational demands, designers' skillsets and the organisation of design activities. We introduce the pragmatic evaluation model, a framework to cyclically evaluate and evolve design methods in professional design practice. The proposed model can provide opportunities for research aimed at understanding how design methods can be adapted and evolved to support professional design practice.

Stress appraisals of UK soccer academy coaches: an interpretative phenomenological analysis

Knowledge of how sports coaches appraise stress is sparse. This study investigates coaches’ cognitive appraisals and explores the transactional nature of how coaches experience stress. Ten academy soccer coaches were interviewed using a semi-structured guide. Interpretative phenomenological analysis was employed to explore coaches’ lived experiences of stressful situations. Coaches identified a range of situational demands including performance expectations, conflicting tasks, and managing relationships. Demands were evaluated in terms of perceived psychological danger. Coaches appraised their ability to meet these demands through resources such as self-efficacy, autonomy and social support. Emotional and behavioural consequences of coaches’ cognitive appraisals were also revealed. Findings provide a deeper understanding into the specific cognitive appraisals of coaches, revealing that determinants of stress appraisals are interdependent and complex.

Training Needs for Adaptive Coordination: Utilizing Task Analysis to Identify Coordination Requirements in Three Different Clinical Settings

A team’s ability to coordinate and adapt their performance to meet situational demands is critical to excellent patient care. The goal of this article is to identify common coordination characteristics that enable health care action teams to ensure effective patient care and to discuss specific examples of adaptive coordination within the health care setting. Task analyses were conducted to identify situational demands, in three different clinical settings: cardiac anesthesia, pediatric sepsis simulation, and trauma resuscitation. Each task analysis identified specific coordination requirements for pertinent tasks. The research team compared these task analyses, identified emerging themes, and agreed on core coordination characteristics common across all three environments by consensus through iterative abductive analysis. Findings across these diverse clinical settings showed that expert action teams (a) continually appraise their dynamic environment, (b) identify and define points of coordination, and (c) respond to the demands of nonroutine events by making coordination highly explicit. Specific examples of adaptive coordination within the health care setting are discussed, and implications for training are articulated. Findings are also pertinent outside of health care and may contribute to the understanding of coordination behaviors within action teams across multiple settings.

Eyewitness Memory in Face-to-Face and Immersive Avatar-to-Avatar Contexts.

Technological advances offer possibilities for innovation in the way eyewitness testimony is elicited. Typically, this occurs face-to-face. We investigated whether a virtual environment, where interviewer and eyewitness communicate as avatars, might confer advantages by attenuating the social and situational demands of a face-to-face interview, releasing more cognitive resources for invoking episodic retrieval mode. In conditions of intentional encoding, eyewitnesses were interviewed 48 h later, either face-to-face or in a virtual environment (N = 38). Participants in the virtual environment significantly outperformed those interviewed face-to-face on all episodic performance measures – improved correct reporting reduced errors, and increased accuracy. Participants reported finding it easier to admit not remembering event information to the avatar, and finding the avatar easier to talk to. These novel findings, and our pattern of retrieval results indicates the potential of avatar-to-avatar communication in virtual environments, and provide impetus for further research investigating eyewitness cognition in contemporary retrieval contexts.

Re-actualizing a cultural exclusion zone

The rise of modernity in the 19th century can, among other things, be vividly illustrated by the phenomenal advance of medical profession and, in particular, surgery as its most radical form. In the 20th century, the doctor has already been steadily associated with the phenomenon of power. Medical experiments on human subjects are generally recognized as one of the most extreme manifestations of this discursive nexus. Despite considerable amount of historical research, predominantly dealing with the experiences of Nazi medicine and its patients in concentration camps and some other disciplinary institutions, as well as somewhat gloomy attraction providing for unabated fascination on the part of trivial literature, such experiments have not yet become an established literary topos. The elusive nature of this phenomenon which belongs to the kern of post-war anxiety, but is rarely addressed to, allows me to attest to the fact that human experiments, especially those conducted in Nazi concentration camps, have become a cultural «exclusion zone». Nonetheless, there is a whole range of texts in which attempts has been made to overcome the cultural taboo and to give voice to the victims of human vivisection. Two of them – Friedrich Durrenmatt’s Suspicion and Marcel Beyers The Flying Foxes – are analyzed in this paper against the backdrop of the so called «intellectual witness» – a concept proposed by Geoffrey Hartman and meaning a distanced witnessing, mostly on behalf of younger generations or, as in case with Durrenmatt, of those who stayed aside of the World War II. In both novels, the narrative structures of intellectual witnessing serve to surmount the metaphorizing tendency which turns the reality of human experiments into tropes corroborating the author’s idea or concept. Combining documentary elements with the elements of trivial fiction, Durrenmatt and Beyer make significant strides in deconstructing the naive «over-identifying» with the victims, as well as their overt fictionalization. As a result, they manage to open the possibility of witness beyond the perspective of eyewitnesses, and at the same time subjugate this rearticulation of the past to the demands of the present situation that facilitates it. This perilous duality reveals the ethical double bind which seems to be inherent to the most reactualizations of utterly traumatic historical experiences, such as human experimentation, transformed into «exclusion zones» and then voiced through intellectual witness and other forms of «secondary witness». In order to become an object of witnessing, those traumatic experiences must correspond to the anxieties of the present originating from them. While triggering the reactualization process, such anxieties, however, also subject the experience of concrete victims to the desiderata of a traumatized «(intellectual) witness» and, in such a way, misuse the tragedy as a means of the witness’s coming to terms with his or her own trauma.

Concepts, control, and context: A connectionist account of normal and disordered semantic cognition.

Semantic cognition requires conceptual representations shaped by verbal and nonverbal experience and executive control processes that regulate activation of knowledge to meet current situational demands. A complete model must also account for the representation of concrete and abstract words, of taxonomic and associative relationships, and for the role of context in shaping meaning. We present the first major attempt to assimilate all of these elements within a unified, implemented computational framework. Our model combines a hub-and-spoke architecture with a buffer that allows its state to be influenced by prior context. This hybrid structure integrates the view, from cognitive neuroscience, that concepts are grounded in sensory-motor representation with the view, from computational linguistics, that knowledge is shaped by patterns of lexical co-occurrence. The model successfully codes knowledge for abstract and concrete words, associative and taxonomic relationships, and the multiple meanings of homonyms, within a single representational space. Knowledge of abstract words is acquired through (a) their patterns of co-occurrence with other words and (b) acquired embodiment, whereby they become indirectly associated with the perceptual features of co-occurring concrete words. The model accounts for executive influences on semantics by including a controlled retrieval mechanism that provides top-down input to amplify weak semantic relationships. The representational and control elements of the model can be damaged independently, and the consequences of such damage closely replicate effects seen in neuropsychological patients with loss of semantic representation versus control processes. Thus, the model provides a wide-ranging and neurally plausible account of normal and impaired semantic cognition.

Versión española del COPE-48: Evaluación del afrontamiento en pacientes psiquiátricos ambulatorios

Introduction: In clinical settings, the COPE questionnaire allows to assess the strategies people use to cope with stressful situations and therefore, if needed, to modify them through psychological treatment. Objective: The aim of this study is to offer to the Spanish-speaking scientific community the Spanish version of the COPE-48 along with the psychometric properties obtained in a sample of adults with psychopathology. Material and Methods: The sample consisted of 301 participants (62.5% women). Results: The average internal consistency of the scales was 0.81. Our results showed a gender pattern in the use of the coping strategies. Conclusions: In clinical settings, the administration of the COPE-48 allows a quick, easy and accurate assessment of the most frequently used strategies to cope with highly demanding situations. This knowledge makes possible to intervene with psychological treatment and whenever appropriate to establish, enhance or minimize the strategies needed to face difficult situations.

A Study On Assessment Of Stress And Its Management In Hospital Employess

Stress refers to the strain from the conflict between our external environment and us, leading to emotional and physical pressure. In our fast paced world, it is impossible to live without stress, whether you are a student or a working adult. There is both positive and negative stress, depending on each individual’s unique perception of the tension between the two forces. Stress bears deliberating effects on both the employees and the employer. As per Dr H seyles, Stress is defined as “a state of psychological and physiological imbalance resulting from the disparity between situational demand and the individual’s ability and motivation to meet those needs”. The word stress has its origin in the Latin word string ere to draw tight. In the 17thcentury the word was used to describe affliction and hardship. The meaning of the word later included the concepts of pressure, strain or force. Today the description of stress includes an outside stimulus and the person’s response to it. Several studies have focused on the possible relation between stress, illness and different ways people respond to it. These studies distinguish the various aspects of stress which a person may face in life, e.g. stress at home, in personal life or at work. This review focuses on stress at work, with particular emphasis to the nursing profession, in an attempt to explore possible management strategies that may decrease it (Golubic etal., 2009, Lu et al. 2009).

Mindfulness and leadership flexibility

PurposeIn a context of great complexity, many authors have focused on the beneficial effects of leadership flexibility (Denison et al., 1995), a capacity theoretically associated with mindfulness. The purpose of this paper is to better understand the relationship between mindfulness and behavioral flexibility in leaders.Design/methodology/approachData were collected from two samples: 100 active leaders from diverse economic sectors and 62 students pursuing an executive MBA degree.FindingsThe results show that mindfulness is positively associated with the overall score for leader flexibility, and with its two dualities: self-assertive and directive vs collaborative and supportive, and long-term strategy vs short-term execution. Specifically, four of the five dimensions of mindfulness (nonreactivity, nonjudging, acting with awareness and describing) were positively correlated with the overall flexibility score.Practical implicationsThe results suggest that by developing mindfulness, managers might be better able to adapt their leadership style to the demands of different situations. To that end, interventions based on mindfulness are worthwhile options for use within organizations, particularly in the context of leadership development programs.Originality/valueWhile most models of leadership assume a linear relationship between certain leadership behaviors and performance, other voices suggest that effective leaders need to possess great behavioral flexibility so that they can adapt with agility to the multiple needs of the people and situations around them. Few studies have examined the factors that may play a role in leadership flexibility.

Victim Precipitation: Let's Not Silence That Voice

Cortina, Robello, and Holland (2018) advance a case for the danger of using the victim precipitation model in industrial-organizational (I-O) psychology—a model that is interpreted as suggesting that characteristics and behaviors of victims may influence criminals to select them as targets, in effect blaming victims for crimes committed against them. This “victim blaming” found its way into criminology, criminal justice, sociology, and other disciplines, resulting in revictimization and in the exoneration of violent criminals, among other undesirable outcomes. We agree with Cortina and colleagues that these outcomes, then and now, are unacceptable: Victims cannot and should not be blamed for their aggressors’ actions, and aggressors should unequivocally be held accountable for their crimes. This extends to workplace mistreatment. Using the operationalizations of generalized workplace harassment, workplace incivility, sexual harassment, and abusive supervision as guides (Rospenda & Richman, 2004, as cited by Cortina et al., 2018; Magley, Williams, & Langhout, 2001; Tepper, 2000; Walsh & Magley, 2014), we define workplace mistreatment as any interpersonal interaction in the workplace that creates an oppressively intimidating, hostile, or offensive working environment that extends beyond acceptable evaluative and professional actions given situational demands (e.g., poor performance reviews, layoffs during downsizing/mergers/acquisitions, discipline, etc.). Although an unpopular point of view, we maintain that whether or not victims influence the contexts that facilitate victimization in the workplace is an empirical question. This research continues to be scientifically valuable, relevant, and practical, and it is necessary to more fully understand workplace mistreatment (Barling, 1996; Cortina, Magley, Williams, & Langhout, 2001). Two principal reasons drive this position: (a) the lack of scientific, data-driven evidence to support the exclusion of the victim precipitation model and (b) the potential harmful premise of its replacement, the perpetrator predation model. Elucidating our thoughts on these reasons will occupy our commentary.

Human echolocators adjust loudness and number of clicks for detection of reflectors at various azimuth angles.

In bats it has been shown that they adjust their emissions to situational demands. Here we report similar findings for human echolocation. We asked eight blind expert echolocators to detect reflectors positioned at various azimuth angles. The same 17.5 cm diameter circular reflector placed at 100 cm distance at 0°, 45° or 90° with respect to straight ahead was detected with 100% accuracy, but performance dropped to approximately 80% when it was placed at 135° (i.e. somewhat behind) and to chance levels (50%) when placed at 180° (i.e. right behind). This can be explained based on poorer target ensonification owing to the beam pattern of human mouth clicks. Importantly, analyses of sound recordings show that echolocators increased loudness and numbers of clicks for reflectors at farther angles. Echolocators were able to reliably detect reflectors when level differences between echo and emission were as low as −27 dB, which is much lower than expected based on previous work. Increasing intensity and numbers of clicks improves signal-to-noise ratio and in this way compensates for weaker target reflections. Our results are, to our knowledge, the first to show that human echolocation experts adjust their emissions to improve sensory sampling. An implication from our findings is that human echolocators accumulate information from multiple samples.

Does mood help or hinder executive functions? Reactivity may be the key

Our ability to utilize executive functioning (EF) in day-to-day life is influenced by our mood, which consists of two fundamental dimensions reflecting positive and negative affect. It remains unclear, however, what impact these affective experiences have on our executive skills and whether this association may be influenced by individual differences in emotional reactivity. Our study investigated the interplay of emotional reactivity, naturally occurring variations in affective dimensions underlying mood, and latent constructs of response inhibition and working memory in an undergraduate sample. Reactivity moderated an association between negative affect and EF, such that high-reactive individuals performed better on EF tasks when experiencing high levels of negative affect whereas low-reactive individuals showed the converse pattern. These results are discussed through the lens of mood-related effects on information processing styles and the availability of cognitive resources to cope with current situational demands. An implication of this work is that emotional reactivity is an important factor in understanding how affective experiences influence executive skills and, by extension, everyday function.

Perfectionistic Cognitions: Stability, Variability, and Changes Over Time

ABSTRACTThe construct of perfectionistic cognitions is defined as a state-like construct resulting from a perfectionistic self-schema and activated by specific situational demands. Only a few studies have investigated whether and how perfectionistic cognitions change across different situations and whether they reflect stable between-person differences or also within-person variations over time. We conducted 2 studies to investigate the variability and stability of 3 dimensions of perfectionistic cognitions while situational demands changed (Study 1) and on a daily level during a highly demanding period of time (Study 2). The results of both studies revealed that stable between-person differences accounted for the largest proportion of variance in the dimensions of perfectionistic cognitions and that these differences were validly associated with between-person differences in affect. The frequency of perfectionistic cognitions increased during students' first semester at university, and these average within-person changes were different for the 3 dimensions of perfectionistic cognitions (Study 1). In addition, there were between-person differences in the within-person changes that were validly associated with concurrent changes in closely related constructs (unpleasant mood and tense arousal). Within-person variations in perfectionistic cognitions were also validly associated with variations in unpleasant mood and tense arousal from day to day (Study 2).

The Main Trends and Principles of Modern Linguistics

The article identifies and describes the main trends and principles of modern linguistics such as integrativity, anthropocentricity, communicativeness, dialogicness, discursiveness, culturecentricity, interest in deep language knowledge, which interact even in one research. Taking the human factor into account is the most important characteristic of post-nonclassical science, and therefore the anthropocentric vector of modern linguistic research contributes to the emergence of most of these principles. In the twenty-first century, all humanities including linguistics are changing under the new demands of the modern social situation: first of all, due to a higher level of synthesis of humanities, their integrativity not only among themselves, but also with natural sciences. For such a complex research object as language, representatives of many sciences can contribute - from molecular biology, genetics, neurophysiology and psychology to anthropology, neurolinguistics and analytical philosophy. Research specialization should be found, as V.I. Vernadsky points out, “not in science, but in problems”, because the removal of information barriers between the sciences gives a powerful impetus for the research development. Thanks to these tendencies and principles, linguistics started exploring the problems that previously were not part in its sphere of interest. Now the sphere of interest of linguistics includes everything that meets the requirements of sign systems theory and allows to see the deep semantic foundations of language, human mentality and culture.
