High-Intensity Interval Training vs. Repeated-Sprint Training in Tennis

Fernandez-Fernandez, J, Zimek, R, Wiewelhove, T, and Ferrauti, A. High-intensity interval training vs. repeated-sprint training in tennis. J Strength Cond Res 26(1): 53–62, 2012—The aim of this study was to compare the effects of high-intensity interval training (HIIT) and repeated-sprint training (RST) on aerobic fitness, tennis-specific endurance, linear and repeated-sprint ability (RSA), and jumping ability. Thirty-one competitive male tennis players took part in a training intervention of 6 weeks. The players were matched into 3 groups, HIIT (n = 11), RST (n = 12), or control group (CON, n = 9). The results showed significant time × intervention interactions for &OV0312;O2peak, with a significant increase in the &OV0312;O2peak level of 6.0% in HIIT (p = 0.008) and 4.9% in RST (p = 0.010), whereas no changes occurred in CON. However, the following differences were found between the intervention groups: The HIIT-induced greater improvements in tennis-specific endurance (HIIT 28.9% vs. RST 14.5%; p < 0.05) and RST led to a significant improvement in RSA (i.e., reduction in the mean sprint time of 3.8%; p < 0.05). Neither training strategy induced any effects on jumping and sprinting abilities. Both training interventions showed similar improvements in general aerobic fitness. Also, the present results suggest that RST represents a time-efficient stimulus for a simultaneous improvement of general and tennis-specific aerobic fitness as well for RSA.
Professional and Personal Factors Associated with Gerontological Practice: Implications for Training and Education

Professional practice with older adults is performed in a variety of settings and across a broad range of areas. Planning for care throughout the end of life represents an increasingly important aspect of work with older adults as a result of the nation's aging demographic and concomitant health care needs. Community-based geriatric case managers represent a growing cadre of professionals encountering frail older adults with future care needs that can be anticipated in advance; however, little is known regarding specific professional and personal factors associated with greater practice in this area. This article presents the findings from a study of 148 community-based case managers' advance care planning practices, conducted in the Southeastern United States. Correlational analyses revealed specific gerontological skills, educational activities, and personal experiences in advance care planning that was highly correlated with practice. Implications for training are discussed.
The Effect of Perceived Value, Satisfaction and Self-Congruity on the Revisit Intention and the Word-of-Mouth Intention

As competition increases, ski resort managers need to search for ways to attract previous visitors or to gain new visitors through word-of-mouth. This study examined the impact of skiers` perceived value, satisfaction and self-congruity on the revisit intention and the positive word-af-mouth intention. Total respondents were also segmented into a promotion-focus and prevention-focus individuals then later examined the differences in the effect of independent variables between groups in order to suggest a managerial direction that will enhance business competency of ski resorts. Results from regression analysis showed that all independent variables utilized in this study were good predictors of two dependent variables. Specially, satisfaction was a highly significant predictor. Promotion and prevention-focused individuals were also differed in evaluating the importance of independent variables for their revisit and word-of-mouth intention. It means that self-regulatory focus is an effective variable for segmentation. More specifically, satisfaction was the only variable influencing the revisit intention for promotion-focused individuals; whereas both satisfaction and self-congruity had significant effects on the revisit intention for prevention-focused individuals. All independent variables had significant effects on the word-of-mouth intention, except self-congruity for promotion-focused individuals. This research suggests several managerial implications on the findings based on the analysis and the characteristics of the visitors.
Atrial Natriuretic Peptide Decreases Circulatory Capacitance in Areflexic Rats

The short-term hemodynamic response to atrial natriuretic peptide appears to be partly mediated by decreased venous return, which could result from increased circulatory capacitance or decreased blood volume. To determine if rat atrial natriuretic peptide 99–126 (0.5 μg/kg/min IV for 30–70 minutes) dilated capacitance vessels or decreased blood volume, mean circulatory filling pressure (measured during brief circulatory arrest by inflating an intraatrial balloon) and blood volume (5lCr-erythrocytes) were measured in anesthetized rats. Mean circulatory filling pressure, central venous pressure, and blood volume decreased by 0.4 mm Hg, 0.5 mm Hg, and 3.4 ml/kg, respectively. To determine the total circulatory pressure-volume relationship without influence from autonomic reflexes, mean circulatory filling pressure and blood volume were measured in spinal-cord-transected rats before and immediately after infusing or withdrawing 5 ml blood. Atrial natriuretic peptide decreased mean circulatory filling pressure, central venous pressure, and blood volume by 0.9 mm Hg, 1.7 mm Hg, and 8.0 ml/kg, respectively, and displaced the pressure-volume relationship toward the pressure axis by decreasing extrapolated unstressed volume. Similar results were obtained in spinal-cord-transected rats that had initial vascular tone restored to a greater level by noreplnephrine infusion. In anephric rats, atrial natriuretic peptide decreased central venous pressure by 0.3 mm Hg and blood volume by 1.6 ml/kg. The results indicate that short-term infusion of atrial natriuretic peptide reduced circulatory capacitance in rats and suggest that this reduction resulted from 1) diminished blood volume due to urinary fluid loss followed by passive vascular recoil and 2) active venoconstriction. These findings are consistent with the hypothesis that intravascular volume contraction and increased resistance to venous return are factors that contribute to the diminished venous return following atrial natriuretic peptide.
Just-In-Time Adaptive Intervention to Sit Less and Move More in People With Type 2 Diabetes: Protocol for a Microrandomized Trial

Background Reducing sedentary behavior and increasing physical activity in people with type 2 diabetes (T2D) are associated with various positive health benefits. Just-in-time adaptive interventions offer the potential to target both of these behaviors through more contextually aware, tailored, and personalized support. We have developed a just-in-time adaptive intervention to promote sitting less and moving more in people with T2D. Objective This paper presents the study protocol for a microrandomized trial to investigate whether motivational messages are effective in reducing time spent sitting in people with T2D and to determine what behavior change techniques are effective and in which context (eg, location, etc). Methods We will use a 6-week microrandomized trial design. A total of 22 adults with T2D will be recruited. The intervention aims to reduce sitting time and increase time spent standing and walking and comprises a mobile app (iMove), a bespoke activity sensor called Sedentary Behavior Detector (SORD), a messaging system, and a secured database. Depending on the randomization sequence, participants will potentially receive motivational messages 5 times a day. Results Recruitment was initiated in October 2022. As of now, 6 participants (2 female and 4 male) have consented and enrolled in the study. Their baseline measurements have been completed, and they have started using iMove. The mean age of 6 participants is 56.8 years, and they were diagnosed with T2D for 9.4 years on average. Conclusions This study will inform the optimization of digital behavior change interventions to support people with T2D Sit Less and Move More to increase daily physical activity. This study will generate new evidence about the immediate effectiveness of sedentary behavior interventions, their active ingredients, and associated factors.

Sensitivity of the Human Binaural Cortical Steady State Response to Interaural Level Differences

Objectives: Periodic alternations of the interaural correlation of a noise stimulus evoke an auditory steady state response that can be measured at the scalp, providing an objective measure of binaural integration. The purpose of this study was to examine the effect of interaural level differences on this steady state response. Design: Auditory steady state responses at 4 and 8 Hz were recorded to 4 Hz cycles of interaural correlation change of a Gaussian noise in normal-hearing listeners. Responses were recorded with symmetric presentation levels of 80, 60, and 40 dB SPL and with interaural asymmetries ranging from 10 to 40 dB, varying in 10-dB steps. Results: The 8 Hz response was sensitive to interaural level asymmetry and fell to 50% strength at an asymmetry of 18 dB, although the response was detectable to an asymmetry of 30 dB. A simultaneously present 4 Hz response showed no sensitivity to interaural level difference. Significant responses were recorded in all participants. Conclusions: The 8 Hz auditory steady state response to a 4 Hz change in noise interaural correlation might be useful as an objective measure of binaural integration in asymmetric hearing loss. Response amplitude is more negatively affected by small amounts of interaural asymmetry than by large reductions in overall presentation level.
Organizational development facilitates effective regulation compliance

Purpose – Aims to explain how application of organizational development (OD) can facilitate compliance with regulations imposed by an external government agency on university operations.Design/methodology/approach – A total of 2,000 students and 150 staff were directly affected by the regulation, with the remaining university population potentially affected.

OD worked well within the devolved, multi‐campus, multidisciplinary and organizationally complex environment of the university. OD proved to .
PARENTAL/SOCIAL INFLUENCES ON PERFECTIONISM AND ADULT ATTACHMENT ORIENTATIONS

Abstract We developed and tested a model for predicting insecure adult attachment orientations that includes indexes of parental expectations and criticism along with measures of adaptive and maladaptive perfectionism. Parental and social performance expectations were significant predictors of adaptive and maladaptive perfectionism. Maladaptive perfectionism was found to fully mediate associations involving parental and other social performance expectations and our indices of adult attachment orientation. Adaptive perfectionism, though significantly associated with adult attachment orientations, was not found to mediate this relationship. Moderator effects also were found between the different forms of parental and social influences in their prediction of adult attachment orientations, with parental criticism emerging as a key enhancing negative factor. Results position perfectionism as a personality characteristic that develops in part from parental relational influences and that holds implications for c.
Perceptions of academic quality and approaches to studying among disabled and nondisabled students in distance education

There is little systematic evidence on the experience of disabled students in higher education. In this study, equal numbers of disabled and nondisabled students taking courses with the UK Open University were surveyed with regard to their approaches to studying and perceptions of the academic quality of their courses. Students with dyslexia or other specific learning difficulties, students with mental health difficulties and students with fatigue were more likely to exhibit a surface approach, and less likely to exhibit organised studying, than were nondisabled students. In the first two groups, this was associated with lower ratings of the quality of their courses. Nevertheless, the differences were not large, either in absolute terms or in the proportion of variance in the students’ scores that they explained. The impact of disability on students’ perceptions of the academic quality of their courses and on their approaches to studying appears to be relatively slight.
Perceptions of Opinion “Climates” and Willingness to Discuss the Issue of Abortion

This 1986 survey of 432 Madison, Wisconsin, residents describes an elaborated version of Elisabeth Noelle-Neumann's model of the “spiral of silence. ” Consistent with her hypotheses, persons whose opinions were congruent with those of the national majority were more willing to speak to a stranger than were those whose opinions were shared only by a minority; however, the same result was not obtained for either a different mode of expression or system level. Factors such as involvement and knowledge were found to directly influence opinion expression, whereas education and gender were found to be indirectly related to expression.
Design and implementation of data survival in unattended wireless sensor networks

In Wireless Sensor Networks, the base station is generally the only unconditionally trusted entity. If it is not connected for a period of time, the network is left unattended and sensor nodes cannot offload data in real time. Thus, until the base station becomes available, adversaries can compromise some sensor nodes and selectively destroy data. In order to prevent such attacks, providing the so-called “data survival”, some strategies can be employed. In this paper, we propose a new strategy based on the concept of secure multi-party protocols. The main advantages of the proposed strategy are not limited to the security, since it (1) preserves privacy, (2) enables the use o data aggregation, (3) enforces a level of trust among nodes, which collaborate to compute functions. Additionally, we implement and evaluate the proposed solution using a real sensor platform. Results show the low cost of the scheme in terms of energy consumption and processing time.
A Longitudinal Analysis of Job Satisfaction, Commitment, and Intention to Leave

Investigators of the relationship among the two attitude measures: Job satisfaction and job commitment, and intention to leave a job, generally used cross-sectional analysis. Using a longitudinal design over a five-month period, the present study examined the causal link between intention to leave and each of the attitude measures. A total of 39 policemen agreed to complete the questionnaire twice. Results showed that an increase in commitment causes a decrease in the intention to leave. Although not significant, the trend for job satisfaction was in the same direction. Intention to leave was not a cause of either attitude measure. Some of the implications of the present findings and suggestions for future research are discussed. Les etudes sur la relation entre l'intention de quitter son emploi et les mesures des deux attitudes que sont la satisfaction et l'implication au travail ont generalement fait appel a la methode transversale. A partir d'un plan d'enquete longitudinal s'etendant sur une periode de cinq mois, notre recherche a porte sur le lien causal existant entre le projet de demission et chacune des deux attitudes. 59 agents de police ont accepte de remplir deux fois le questionnaire. Il apparait qu'un accroissement de l'implication entraine un declin du projet de depart. Il en est de meme pour la satisfaction professionnelle, bien que le liaison ne soit pas significative. L'envie de demissionner ne determine aucune des deux mesures d'attitudes. On examine les consequences de ces resultats et des suggestions pour les recherches a venir sont avancees.
The Field Trip Milieu: Learning and Behavior as a Function of Contextual Events.

AbstractA Study to assess the impact of school field trips on attitudes, behavior, and learning was conducted with 1% third and fifth grade children. Half the children went on an all-day field trip to a nature center to learn about the biology of trees; the other half were taught the same lesson outside their classroom during their regular science period. As measured by pre- and posttests, field experiences resulted in significant immediate learning and 30-day retention for all groups. Observational measures revealed that student behavior varied as a function of age and environmental context. A model is proposed that relates learning and behavior to both developmental level and environmental novelty.
The GDNF-GFRα1 complex promotes the development of hippocampal dendritic arbors and spines via NCAM

The formation of synaptic connections during nervous system development requires the precise control of dendrite growth and synapse formation. Although glial cell line-derived neurotrophic factor (GDNF) and its receptor GFRα1 are expressed in the forebrain, the role of this system in the hippocampus remains unclear. Here, we investigated the consequences of GFRα1 deficiency for the development of hippocampal connections. Analysis of conditional Gfra1 knockout mice shows a reduction in dendritic length and complexity, as well as a decrease in postsynaptic density specializations and in the synaptic localization of postsynaptic proteins in hippocampal neurons. Gain- and loss-of-function assays demonstrate that the GDNF-GFRα1 complex promotes dendritic growth and postsynaptic differentiation in cultured hippocampal neurons. Finally, in vitro assays revealed that GDNF-GFRα1-induced dendrite growth and spine formation are mediated by NCAM signaling. Taken together, our results indicate that the GDNF-GFRα1 complex is essential for proper hippocampal circuit development. Summary: Postsynaptic engagement of GDNF and GFRα1 is required for proper development of hippocampal dendritic arbors and spine maturation through NCAM signaling.
Calibration Research: Where Do We Go from Here?

Research on calibration remains a popular line of inquiry. Calibration is the degree of fit between a person’s judgment of performance and his or her actual performance. Given the continued interest in this topic, the questions posed in this article are fruitful directions to pursue to help address gaps in calibration research. In this article, we have identified six research directions that if productively pursued, could greatly expand our knowledge of calibration. The six research directions are: (a) what are the effects of varying the anchoring mechanisms from which calibration judgments are made, (b) how does calibration accuracy differ as a function of incentives and task authenticity, (c) how do students self-report the basis of their calibration judgments, (d) how do group interactions and social comparisons affect calibration accuracy, (e) what is the relation between absolute and relative accuracy, and (f) to what extent does calibration accuracy predict achievement? To help point the way to where we go from here in calibration research, we provide these research questions, propose research methods designed to address them, and identify prior, related studies that have shown promise in leading the way to fill these gaps in the literature.
Transfer of Carbon Dioxide within Cultures of Microalgae: Plain Bubbling versus Hollow‐Fiber Modules

In attempts to improve the metabolic efficiency in closed photosynthetic reactors, availability of light and CO2 are often considered as limiting factors, as they are difficult to control in a culture. The carbon source is usually provided via bubbling of CO2‐enriched air into the culture medium; however, this procedure is not particularly effective in terms of mass transfer. Besides, it leads to considerable waste of that gas to the open atmosphere, which adds to operation costs. Increase in the interfacial area of contact available for gas exchange via use of membranes might be a useful alternative; microporous membranes, in hollow‐fiber form, were tested accordingly. Two hollow‐fiber modules, different in both hydrophilicity and outer surface area, were tested and duly compared, in terms of mass transfer, versus traditional plain bubbling. Overall volumetric coefficients (KLa) for CO2 transfer were 1.48 × 10−2 min−1 for the hydrophobic membrane, 1.33 × 10−2 min−1 for the hydrophilic membrane, and 7.0 × 10−3 min−1 for plain bubbling. A model microalga, viz. Nannochloropsis sp. , was cultivated using the two aforementioned membrane systems and plain bubbling. The produced data showed slight (but hardly significant) increases in biomass productivity when the hollow‐fiber devices were used. However, hollow‐fiber modules allow recirculation of unused CO2, thus reducing feedstock costs. Furthermore, such indirect way of supplying CO2 offers the additional possibility for use of lower gas pressures, as no need to counterbalance hydrostatic heads exists.
External and Internal Morphology of the BAR 1002'00 Orrorin tugenensis Femur

Late Miocene fossils from the Lukeino Formation in Kenya's Tugen Hills are assigned to Orrorin tugenensis. Of 20 fossils recovered there to date, 3 are proximal femurs. One of these, BAR 1002′00, preserves an intact head connected to the proximal shaft by an elongated neck. Although this fossil is comparable in size to Pan troglodytes, computerized tomography scans of the neck-shaft junction of BAR 1002′00 reveal that the cortex is markedly thinner superiorly than inferiorly, differing from the approximately equal cortical thicknesses observed in extant African apes, approaching the condition in later hominids, and indicating that O. tugenensis was bipedal.
Objects-in-Use and Organizing in Action Nets

In this article, the authors engage in, and contribute to, the discussion about the role of objects (material arrangements) in processes of organizing. The point of departure of the study was a critical incident at a hospital when a drop infusion pump failed. By following the action, that is, to apply an action net perspective, initiated by incident aiming to secure the ongoing care and treatment of patients on the ward, the authors are able to illustrate the relation between objects-in-use (such as boundary objects) and ongoing organizing practices, and how such organizing activities are dependent on, and conditioned by, material arrangements and objects. Furthermore, they also show that objects, far from being stable entities, are also being constructed, deconstructed, and reconstructed—dependent on what is appropriate in a specific time and place, and as part of ongoing organizing.
