R U with Some1? Using Text Message Experience Sampling to Examine Television Coviewing as a Moderator of Emotional Contagion Effects on Enjoyment

Viewers regularly watch television with others, but the role of coviewing is often overlooked in entertainment effects models. Further, the models are rarely investigated in natural settings, limiting their ecological validity. The current study used experience sampling via text message to examine college students’ daily coviewing behaviors. Momentary assessments were taken 3 times a day for 1 week. Respondents reported their happiness during viewing and the enjoyableness of their experiences. Consistent with emotional contagion theory, data suggest that increases in emotional intensity mediated the effect of emotional contagion on program enjoyment, but only among respondents who reported coviewing with someone else. These results provide preliminary evidence that social context is partially responsible for contagious transfer of affect during entertainment experiences.     

Centered but not Caught in the Middle: Stepchildren's Perceptions of Dialectical Contradictions in the Communication of Co-Parents

The researchers adopted a dialectical perspective to study how stepchildren experience and communicatively manage the perception of feeling caught in the middle between their parents who are living in different households. The metaphor of being caught in the middle is powerful for stepchildren and this metaphor animated their discourse. A central contribution of the present study was to understand the alternative to being caught in the middle and what this alternative means to stepchildren. Reflected in the discourse of stepchildren is that to feel not caught in the middle is to feel centered in the family. Stepchildren's desire to be centered in the family was animated by the dialectic of freedom–constraint, which co-existed within the contradictions of openness–closedness and control–restraint. These contradictions are detailed in the analysis, along with advice to parents from the perspective of stepchildren. Implications for the interaction of stepchildren and their parents are discussed.     

The Librarian's Role in Linking Patients to Their Personal Health Data and Contextual Information

The objective of this project was to make an institution's patients aware of a new patient portal with contextual links to MedlinePlus. Through partnerships with information technology personnel and LSU Health Shreveport clinics, the Health Sciences Library created and distributed promotional and educational materials and instructed patients on how to use MyChart and access reliable consumer health information via MedlinePlus Connect. Although most patients were not interested in coming to the library for demonstrations, many of them expressed interest in using MyChart. The contextual information in MedlinePlus Connect worked well for most topics. The institutional team leader for MyChart expressed gratitude for librarian involvement.     

Conservation from conception: Commissioning an installation by Cai Guo-Qiang

Over a period of six years, the Queensland Art Gallery / Gallery of Modern Art and Chinese artist Cai Guo-Qiang developed and realized the major art installation Heritage (2013). The artwork comprises 99 life-sized imitation animals congregating at a waterhole and covers 1104 m² of floor space. This paper reviews aspects of the commission, construction, and completion of Heritage – a very large-scale, technically complex contemporary installation. From commission to acquisition, the project was a highly collaborative undertaking and is an interesting example of unconventional conservation. This paper, written from curatorial and conservation perspectives, describes this cooperative endeavour.     

The Family Environment of “Quick-Witted” Persons: Birth Order,Family Communication Patterns,and Creative Facility

“Creative facility” refers to the ease, rapidity, or fluency with which people are able to formulate and produce novel, appropriate messages. Previous research indicates that people differ in this regard and that the phenomenon is linked to various personality and cognitive-style variables. This study aims to investigate whether aspects of family structure (i.e., birth order) and family processes (i.e., family communication patterns) are related to creative facility. Results indicated a significant interaction between birth order and family conversation orientation such that, for first-borns, higher levels of conversation orientation were associated with slower message production. No effects were observed for family conformity orientation. Among the implications of the findings is the need to assess birth order in studies of family communication patterns.     

Effects of strength and endurance exercise order on endocrine responses to concurrent training

The present study examined the effect of strength and endurance training order on the endocrine milieu associated with strength development and performance during concurrent training. A randomised, between-groups design was employed with 30 recreationally resistance-trained males completing one of four acute experimental training protocols; strength training (ST), strength followed by endurance training (ST-END), endurance followed by strength training (END-ST) or no training (CON). Blood samples were taken before each respective exercise protocol, immediately upon cessation of exercise, and 1?h post cessation of exercise. Blood samples were subsequently analysed for total testosterone, cortisol and lactate concentrations. Ability to maintain 80% 1RM during strength training was better in ST and ST-END than END-ST (both p?<?.05). Immediately following the respective exercise protocols all training interventions elicited significant increases in testosterone (p?<?.05). ST and END-ST resulted in greater increases in cortisol than ST-END (both p?<?.05). The testosterone:cortisol ratio was similar following the respective exercise protocols. Blood lactate concentrations post-training were greater following END-ST and ST than ST-END (both p?<?.05). Conducting endurance exercise prior to strength training resulted in impaired strength training performance. Blood cortisol and lactate concentrations were greater when endurance training was conducted prior to strength training than vice versa. As such, it may be suggested that conducting endurance prior to strength training may result in acute unfavourable responses to strength training when strength training is conducted with high loads.     

Influence of cold-water immersion on limb blood flow after resistance exercise*

This study determined the influence of cold (8°C) and cool (22°C) water immersion on lower limb and cutaneous blood flow following resistance exercise. Twelve males completed 4 sets of 10-repetition maximum squat exercise and were then immersed, semi-reclined, into 8°C or 22°C water for 10-min, or rested in a seated position (control) in a randomized order on different days. Rectal and thigh skin temperature, muscle temperature, thigh and calf skin blood flow and superficial femoral artery blood flow were measured before and after immersion. Indices of vascular conductance were calculated (flux and blood flow/mean arterial pressure). The colder water reduced thigh skin temperature and deep muscle temperature to the greatest extent (P?<?.001). Reductions in rectal temperature were similar (0.2–0.4°C) in all three trials (P?=?.69). Femoral artery conductance was similar after immersion in both cooling conditions, with both conditions significantly lower (55%) than the control post-immersion (P?<?.01). Similarly, there was greater thigh and calf cutaneous vasoconstriction (40–50%) after immersion in both cooling conditions, relative to the control (P?<?.01), with no difference between cooling conditions. These findings suggest that cold and cool water similarly reduce femoral artery and cutaneous blood flow responses but not muscle temperature following resistance exercise.     

Effect of 6 weeks of endurance training on the lactate minimum speed

The aim of this study was to assess the sensitivity of the lactate minimum speed test to changes in endurance fitness resulting from a 6 week training intervention. Sixteen participants (mean +/- s: age 23+/-4 years; body mass 69.7+/-9.1 kg) completed 6 weeks of endurance training. Another eight participants (age 23+/-4 years; body mass 72.7+/-12.5 kg) acted as non-training controls. Before and after the training intervention, all participants completed: (1) a standard multi-stage treadmill test for the assessment of VO2max, running speed at the lactate threshold and running speed at a reference blood lactate concentration of 3 mmol x l(-1); and (2) the lactate minimum speed test, which involved two supramaximal exercise bouts and an 8 min walking recovery period to increase blood lactate concentration before the completion of an incremental treadmill test. Additionally, a subgroup of eight participants from the training intervention completed a series of constant-speed runs for determination of running speed at the maximal lactate steady state. The test protocols were identical before and after the 6 week intervention. The control group showed no significant changes in VO2max, running speed at the lactate threshold, running speed at a blood lactate concentration of 3 mmol x l(-1) or the lactate minimum speed. In the training group, there was a significant increase in VO2max (from 47.9+/-8.4 to 52.2+/-2.7 ml x kg(-1) x min(-1)), running speed at the maximal lactate steady state (from 13.3+/-1.7 to 13.9+/-1.6 km x h(-1)), running speed at the lactate threshold (from 11.2+/-1.8 to 11.9+/-1.8 km x h(-1)) and running speed at a blood lactate concentration of 3 mmol x l(-1) (from 12.5+/-2.2 to 13.2+/-2.1 km x h(-1)) (all P < 0.05). Despite these clear improvements in aerobic fitness, there was no significant difference in lactate minimum speed after the training intervention (from 11.0+/-0.7 to 10.9+/-1.7 km x h(-1)). The results demonstrate that the lactate minimum speed, when assessed using the same exercise protocol before and after 6 weeks of aerobic exercise training, is not sensitive to changes in endurance capacity.
