The Remediation of Love: Text Messaging as Writing

Within the range of communications technologies constituting the contemporary mediascape, text messaging on mobile phones (or SMS for short message system, or simply ‘texting’) has been compared, for example, to postcard writing or classic epistolarity (letter writing, as in Goethe’s epistolary novel The Sorrows of Young Werther). What is the nature of the relationship between SMS writing and other forms of ‘classic’ writing? Can text messaging be considered as ‘writing’ at all? Partly inspired by Bolter and Grusin’s notion of remediation, in this essay I will consider text messaging in the context of other media technologies and practices. Bolter and Grusin discuss how media continually engage with each other by re-activating each other’s features in an iterative process. Here, I attempt to illustrate the mutual linkages that position SMS messages within the mediascape. Text messaging feeds off and into other communication practices. Moreover, these linkages change over time, contributing to the practice’s resilience towards certain other communications technologies and its dynamic relationships with others.
Discretionary power on the front line: A bottom-up perspective on corporate language management

This paper investigates the communication practices used by front-line employees to cross language boundaries in the context of English language policies implemented by the management of three multinational corporations (MNCs) headquartered in Scandinavia. Based on an analysis of interview and document data, our findings show that employees face a number of different language boundaries in their everyday work, and that ad hoc and informal solutions in many cases are vital for successful cross-language communication. We introduce the concept of 'discretionary power' to explain how and why front-line employees diverge from the corporate language policies, and emphasise the role of individual agency in the implementation of language policy. With a focus on the communication practices of front-line employees, the paper contributes with a bottom-up, employee-centred perspective on corporate language management, emphasising the importance of paying attention to the micro level of everyday interactions in the study of language policy and practice.
Decreased circulating levels of oxytocin in obesity and newly diagnosed type 2 diabetic patients.

CONTEXT AND OBJECTIVE Oxytocin can affect energy homeostasis and has interesting potential as a metabolic disease therapeutic. We detected serum oxytocin levels in obese (OB) and type 2 diabetes mellitus (T2DM) subjects and investigated the relationships between serum oxytocin levels and glycolipid metabolism, insulin resistance, pancreatic β-cell function, and inflammation. PATIENTS AND METHODS A total of 176 subjects were enrolled in the study, including 88 patients with newly diagnosed T2DM and 88 subjects with normal glucose tolerance (NGT). NGT and T2DM groups were divided into normal-weight (NW) and OB subgroups. We analyzed the concentrations of oxytocin by ELISA. Oral glucose tolerance testing was done, and hemoglobin A1c (HbA1c), blood lipids, and highly sensitive C-reactive protein (hs-CRP) were also measured. Insulin resistance and pancreatic β-cell function were assessed by homeostasis model assessment (HOMA). RESULTS Serum oxytocin levels were lower in the T2DM group than in the NGT group (P < .01). The levels of serum oxytocin in OB subjects were also lower than those in NW subjects (P < .01). Serum oxytocin levels were negatively correlated with body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), HbA1c, fasting plasma glucose (FPG), 2-hour plasma glucose, fasting insulin (FINS), 2-h insulin, total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), HOMA of insulin resistance (HOMA-IR), and hs-CRP and positively correlated with HOMA of β-cell function (HOMA-β) (P < .05). Multiple stepwise regression analysis showed that 2-hour plasma glucose, BMI, and TC were associated with serum oxytocin levels (P < .05). Logistic regression analyses demonstrated that serum oxytocin was significantly associated with T2DM (P < .01). CONCLUSIONS Serum oxytocin levels were decreased in T2DM as well as OB subjects.
A semi-analytical simplified approach to compute lightning radiated electric fields at long distances taking into account ionospheric reflection

In this paper, we present a semi-analytical simplified approach based on the ray tracing method to estimate radiated electric fields associated with lightning return strokes, taking into account ionospheric reflections. The field transfer function at each frequency and each grazing angle is determined by applying the generalized Snell's law of refraction, and the antenna radiation pattern concept is used to obtain the source illumination efficiency, from which the radiated field is derived. The proposed method is validated using as reference full-wave FDTD simulations.
Somatoform disorders: The role of consultation liaison psychiatry

The somatoform disorders are encountered commonly in both primary and secondary care. Despite their high incidence, few hospitals have teams with the expertise to manage this group of conditions. The lack of appropriate carers leads to inappropriate care, including increased numbers of admissions and investigations, to the detriment of the patients. The absence of appropriate care also increases the cost to the health services. Multidisciplinary Consultation Liaison (C-L) Psychiatry teams operate within non-psychiatric settings and are dedicated to the mental health care of patients presenting in these areas. Their unique skills and approaches offer support and education to these non-psychiatric teams and care to this group of patients. They are thus ideally placed to assess, diagnose and manage individuals presenting with somatoform disorders. Unfortunately, these teams are not widely available, largely because the current climate within psychiatry leads services to concentrate on what is defined as serious mental illness, a term usually used synonymously with psychotic disorders, despite the large number of people suffering from somatoform disorders and the cost of their care. The dislike that some colleagues have for this group of conditions may further hamper the creation of these services. In order to provide efficient assessment of and treatment for individuals with somatoform disorders, C-L Psychiatry teams must be created to lead clinical development, research and training in this discipline. These teams will also lead on the further research required.
The role of head movements and signal spectrum in an auditory front/back illusion

We used a dynamic auditory spatial illusion to investigate the role of self-motion and acoustics in shaping our spatial percept of the environment. Using motion capture, we smoothly moved a sound source around listeners as a function of their own head movements. A lowpass filtered sound behind a listener that moved in the direction it would have moved if it had been located in the front was perceived as statically located in front. The contrariwise effect occurred if the sound was in front but moved as if it were behind. The illusion was strongest for sounds lowpass filtered at 500 Hz and weakened as a function of increasing lowpass cut-off frequency. The signals with the most high frequency energy were often associated with an unstable location percept that flickered from front to back as self-motion cues and spectral cues for location came into conflict with one another.
Relationships between training load, injury, and fitness in sub-elite collision sport athletes

Abstract The purpose of this study was to develop statistical models that estimate the influence of training load on training injury and physical fitness in collision sport athletes. The incidence of training injuries was studied in 183 rugby league players over two competitive seasons. Participants were assessed for height, body mass, skinfold thickness, vertical jump, 10-m, 20-m and 40-m sprint time, agility, and estimated maximal aerobic power in the off-season, pre-season, mid-season, and end-season. Training load and injury data were summarised into pre-season, early-competition, and late-competition training phases. Individual training load, fitness, and injury data were modelled using a logistic regression model with a binomial distribution and logit link function, while team training load and injury data were modelled using a linear regression model. While physical fitness improved with training, there was no association (P = 0.16 – 0.99) between training load and changes in physical fitness during any of the training phases. However, increases in training load during the early-competition training phase decreased (P = 0.04) agility performance. A relationship (P = 0.01 – 0.04) was observed between the log of training load and odds of injury during each training phase, resulting in a 1.50 – 2.85 increase in the odds of injury for each arbitrary unit increase in training load. Furthermore, during the pre-season training phase there was a relationship (P = 0.01) between training load and injury incidence within the training load range of 155 and 590 arbitrary units. During the early and late-competition training phases, increases in training load of 175 – 620 arbitrary units and 145 – 410 arbitrary units, respectively, resulted in no further increase in injury incidence. These findings demonstrate that increases in training load, particularly during the pre-season training phase, increase the odds of injury in collision sport athletes. However, while increases in training load from 175 to 620 arbitrary units during the early-competition training phase result in no further increase in injury incidence, marked reductions in agility performances can occur. These findings suggest that reductions in training load during the early-competition training phase can reduce the odds of injury without compromising agility performances in collision sport athletes.
Two Aromatic Residues in the PB2 Subunit of Influenza A RNA Polymerase Are Crucial for Cap Binding*

mRNAs are capped at their 5′-end by a unique cap structure containing N7-methyl guanine. Recognition of the cap structure is of paramount importance in some of the most central processes of gene expression as well as in some viral processes, such as priming of influenza virus transcription. The recent resolution of the structure of three evolutionary unrelated cap binding proteins, the vaccinia viral protein VP39, the eukaryotic translation factor eIF4E, and the nuclear cap-binding protein CBP20 showed that the recognition of the cap structure is achieved by the same general mechanism, i.e. by “sandwiching” of the N7-methyl guanine of the cap structure between two aromatic amino acid residues. The purpose of the present study was to test whether a similar cap recognition mechanism had independently evolved for the RNA polymerase of influenza virus. Combining in vivo and in vitro methods, we characterized two crucial aromatic amino acids, Phe363 and Phe404, in the PB2 subunit of the viral RNA polymerase that are essential for cap binding. The aromaticity of these two residues is conserved in influenza A, B, and C and even in the divergent Thogoto virus PB2 subunits. Thus, our results favor a similar mechanism of cap binding by the influenza RNA polymerase as in the evolutionary unrelated VP39, eIF4E, and CBP20.
Milton Friedman and the Case for Flexible Exchange Rates and Monetary Rules

Milton Friedman was a strong proponent of flexible exchange rates accompanied by a domestic monetary rule. He believed that such a combination would deliver superior economic performance and would also be more consistent with democratic principles than a regime based on fixed exchange rates and discretionary monetary policy. John Taylor’s recent proposal of a rules-based international monetary system –- based on flexible exchange rates and a Taylor rule for each country - is very much in that spirit and represents a modern rendition of Friedman’s views. Under both the Friedman and Taylor proposals, instead of policy coordination among countries there would be policy harmonization.
What Moves Stock Prices? The Role of News, Noise, and Information

We develop a return variance decomposition model to separate the role of different types of information and noise in stock price movements. We disentangle four components: market-wide information, private firm-specific information revealed through trading, firm-specific information revealed through public sources, and noise. Overall, 31% of the return variance is from noise, 37% from public firm-specific information, 24% from private firm-specific information, and 8% from market-wide information. Since the mid-1990s, there has been a dramatic decline in noise and an increase in firm-specific information, consistent with increasing market efficiency.
The density and type of MECA‐79‐positive high endothelial venules correlate with lymphocytic infiltration and tumour regression in primary cutaneous melanoma

Tumour‐infiltrating lymphocytes have prognostic value in malignant melanoma. High endothelial venules (HEVs) are specialized vessels present in lymph nodes and tertiary lymphoid organs. CCL19, CCL21 and CCR7 regulate lymphocyte migration through HEVs. The aim of our study was to correlate HEV density in cutaneous primary and metastatic malignant melanomas with clinicopathological parameters, and with CCL19, CCL21 and CCR7 mRNA expression.
Impact of HSCT Conditioning and Glucocorticoid Dose on Exercise Adherence and Response

Purpose Evidence from randomized controlled trials (RCT) that exercise interventions have beneficial effects in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) is growing. However, intensive chemotherapy conditioning and glucocorticoid (GC) treatment is always part of an allo-HSCT and possibly affect exercise adherence and training response. Therefore, we aimed to examine whether various conditioning protocols or different doses of GC treatment affect exercise adherence and/or training response during the inpatient period. Methods We analyzed inpatient data from intervention groups of two large RCT in allo-HSCT patients (n = 113). The intervention incorporated partly supervised endurance and resistance exercise three to five times per week. According to the potentially interfering factors, the patients were divided into groups depending on intensity of conditioning (myeloablative conditioning (MAC), reduced-intensity conditioning (RIC), and nonmyeloablative conditioning (NMC)) and cumulative dose of GC treatment (GC low ⩽9 mg·kg−1 prednisone or GC high >9 mg·kg−1 prednisone) and were compared. Results Median exercise adherence (target value, five sessions weekly) during the inpatient period was 64% in MAC, 54% in RIC, and 63% in NMC. The proportion of prematurely terminated training sessions ranged from 11% to 15%. Tiredness was the most frequent cause of exercise termination in all groups. Exercise adherence, duration (min·wk1) and type of training was significantly associated with GC dose. With regard to training response, results suggest that GC-low patients tend to respond better in knee extensor muscle strength. Conclusions Exercise adherence during inpatient period is significantly affected by dose of GC treatment but not by condition regimen. However, given the reasonable adherence rates also in the GC-high group, data support the feasibility and importance of exercising for all allo-HSCT patients during the inpatient period.
Financial Structure and Corporate Growth: Evidence from Italian Panel Data

We study the relationships between firm financial structure and growth for a large sample of Italian firms (1998-2003). We expand upon existing analyses testing whether liquidity constraints affect firm performance by considering among growth determinants also firm debt structure. Panel regression analyses show that more liquid firms tend to grow more. However, firms do not use their capital to expand, but rather to increase debt. We also find that firm growth is highly fragile as it is positively correlated with non-financial liabilities and it is not sustained by a long-term debt maturity. Finally, quantile regressions suggest that fast-growing firms are characterized by higher growth/cash-flow sensitivities and heavily rely on external debt, but seem to be less bank-backed than the rest of the sample. Overall, our findings suggest that the link between firms' investment and expansion decisions is far more complicated than postulated by standard tests of investment/cash-flow sensitivities.

Variation of the different attributes that support the physical function in community-dwelling older adults.

AIM This study investigated the variation with age of different attributes that support the physical functioning in community-dwelling older adults having as reference scores from young adults. METHODS The study was a cross-sectional study. Participants were 559 older adults and 79 young adults grouped according to gender and age (Y:20-29, A:60-64, B:65-69, C:70-74, D:75-79 and E:≥ 80 years). Strength, flexibility, agility, aerobic endurance, and balance were evaluated by Fullerton tests. RESULTS ANOVA and Bonferroni post-hoc tests showed that compared to young, the 60-64 years group showed decreased values in almost all attributes of physical function. In older adults, additional differences were observed in females mainly between the 60-64 years group and the 70-74 years, 75-79 years, and:≥ 80 years groups, and in males between the 60-64 years group and the ≥ 80 years group (P<0.05). Comparisons between standardized physical function attributes (T-scores) done by repeated measures and contrasts demonstrated that, across age groups, agility and dynamic balance showed the highest rate loss in both genders, and lower body flexibility showed the lowest (P<0.01). CONCLUSION Physical function reduction seems to occur earlier in women than in men and abilities involving multiple structures such as balance, agility, and aerobic endurance showed the most loss.
Macroalgal blooms alter community structure and primary productivity in marine ecosystems

Eutrophication, coupled with loss of herbivory due to habitat degradation and overharvesting, has increased the frequency and severity of macroalgal blooms worldwide. Macroalgal blooms interfere with human activities in coastal areas, and sometimes necessitate costly algal removal programmes. They also have many detrimental effects on marine and estuarine ecosystems, including induction of hypoxia, release of toxic hydrogen sulphide into the sediments and atmosphere, and the loss of ecologically and economically important species. However, macroalgal blooms can also increase habitat complexity, provide organisms with food and shelter, and reduce other problems associated with eutrophication. These contrasting effects make their overall ecological impacts unclear. We conducted a systematic review and meta‐analysis to estimate the overall effects of macroalgal blooms on several key measures of ecosystem structure and functioning in marine ecosystems. We also evaluated some of the ecological and methodological factors that might explain the highly variable effects observed in different studies. Averaged across all studies, macroalgal blooms had negative effects on the abundance and species richness of marine organisms, but blooms by different algal taxa had different consequences, ranging from strong negative to strong positive effects. Blooms' effects on species richness also depended on the habitat where they occurred, with the strongest negative effects seen in sandy or muddy subtidal habitats and in the rocky intertidal. Invertebrate communities also appeared to be particularly sensitive to blooms, suffering reductions in their abundance, species richness, and diversity. The total net primary productivity, gross primary productivity, and respiration of benthic ecosystems were higher during macroalgal blooms, but blooms had negative effects on the productivity and respiration of other organisms. These results suggest that, in addition to their direct social and economic costs, macroalgal blooms have ecological effects that may alter their capacity to deliver important ecosystem services.
Oral health in the adult population of Skåne, Sweden: a clinical study

Abstract Objective. The aim of this study was to describe the oral health in the adult population of Skåne by clinical factors with special reference to age, gender, ethnicity and education. Materials and methods. Clinical examinations were performed on 451 randomly selected individuals, 20–89 years old, living in Skåne, Sweden. The clinical examination included a radiographic examination and a questionnaire. Clinical variables were put into cross-tabulations along with age, gender, educational level and ethnicity. Results. For all of the described clinical variables, except caries, the frequency increased with age. There were no differences in the clinical variables due to gender. The frequencies of missing teeth, caries, periodontal conditions and DMFT were higher among those with a lower educational level. More missing teeth, worse periodontal conditions, more apical destructions and less dental fillings were found in individuals who were not born in Sweden. Conclusions. The oral health in the adult population of Skåne was overall good, with low frequencies of oral disease and a large number of remaining teeth up to a high age. The patients' oral health status, as determined by a dentist's clinical examination, differed due to age, educational level and ethnicity, but not due to gender.
Dynamic Modeling of a Five-Phase Induction Machine With a Combined Star/Pentagon Stator Winding Connection

The combined star/pentagon connection of five-phase induction machines was recently demonstrated as a promising compromise between conventional star and pentagon connections. It combines the advantages of both star and pentagon connections without any additional hardware for winding changeover. This connection is based on two five-phase single layer concentrated winding sets shifted in space by π/10 and connected in a combined star/pentagon configuration to provide five-phase terminals. Since the combined star/pentagon connected induction machine is fundamentally an asymmetrical ten-phase machine, the machine mathematical model possesses additional subspaces, which affect the behavior of the machine especially under open line conditions. Starting from the conventional five-phase and m -bar squirrel cage induction machine model, the phase-variable model of the combined star/pentagon connection is introduced in this paper. The corresponding equivalent dq model with five decoupled subspaces, which can account for air gap harmonics up to ninth order, is then derived. Finally, it was shown that the machine model could be simply approximated with only two subspaces similar to a conventional five-phase induction machine with sinusoidally distributed winding, where the flux produced by the nonfundamental subspace could be neglected. The model is verified using a 1 kW prototype five-phase induction machine.
