Potential of rainwater resources based on urban and social aspects in Colombia
Authors: Morales‐Pinzón Tito , Rieradevall Joan , Gasol Carles M. , Gabarrell Xavier 
Published: March 2012

AbstractThe potential offered by non‐conventional water resources (rainwater) associated with high or low urban density in new housing in different rainfall zones (800–2300 mm) was studied. Ten cities in Colombia with over 250 000 inhabitants were used as a case study. The potential of substitution of tap water by rainwater according to population groups with different socioeconomic status was estimated. This study reveals the favourable conditions for rainwater harvesting in the Colombian context, and enables the linking of supply and demand issues related to local climatic and environmental sustainability in order to integrate the use of rainwater into urban housing projects. For the current consumption scenario (greater than 160 Lcd), rainwater becomes a potential replacement for mains water in urban areas with rainfall of above 1553 L/m2/year.

Published: March 2012

SummaryIntroduction:  In the case of inflammation, imbalance of iron homoeostasis is caused by increased retention of iron within cells of the reticuloendothelial system. Iron‐restricted erythropoiesis occurs because of decreased availability of iron for haemoglobin (Hb) synthesis in erythroid progenitor cells.Deviations in reticulocyte haemoglobin (Ret‐He) content are investigated together with inflammation markers in subjects with community‐acquired pneumonia (CAP). Short‐term alterations with regard to Ret‐He during and after completing antibiotic treatment are investigated.Methods:  A total of 75 patients, classified into three subgroups with CURB‐65 scores of ≤1, 2 and ≥3, participated in the study.Results:  Within the three subgroups, Hb results demonstrate a decline from the day of admission until day 4. From day 4, an increase towards higher values is observed at day 14. Within 24 h after admission, Ret‐He results are situated within the lower quartile region of the reference range interval. Until day 4 of hospital admission, a steady trend towards a decline of 3–8% is established. During antibiotic treatment, an increase in reticulocyte count occurs from 0.039 ± 0.014 × 1012/L at day 4 to 0.057 ± 0.020 × 1012/L at day 14 (mean ± SD). Recovery of Hb and Ret‐He occurs towards values within the reference range.Conclusion:  In subjects with CAP, acute inflammation results in impairment of Ret‐He at an early stage. After onset of pneumonia, decreased results of Ret‐He and Ret‐He/RBC‐He ratio are demonstrated, reflecting acute erythropoietic dysfunction, which are amongst others caused by functional iron depletion.
A Simplified Mechanistic Algorithm for Treating Resistant Hypertension: Efficacy in a Retrospective Study
Authors: Mann Samuel J. , Parikh Neal S. 
Published: March 2012

J Clin Hypertens (Greenwich). 2012;14:191–197. ©2012 Wiley Periodicals, Inc.This retrospective study assessed the efficacy of a recently described, mechanism‐based algorithm for treating resistant hypertension. Charts of consecutive patients seen for resistant hypertension were reviewed. Algorithm‐based intervention was limited to either or both of just 2 options: (1) strengthening of the diuretic regimen, usually with addition of spironolactone; and (2) treatment with the combination of an α‐ + nonmetabolized β‐blocker. Of 27 patients, 24 (89%) achieved control, including 13 (54%) in whom the diuretic regimen was strengthened, 6 (25%) in whom α‐/β‐blockade was instituted, and 5 (21%) who received both interventions. The most frequent medication adjustments were addition of a potassium‐sparing diuretic in 16 (67%), doxazosin in 9 (37.5%), and replacing a metabolized with a nonmetabolized β‐blocker in 6 (25%). The authors conclude that treatment based on this algorithm can both simplify and improve the management of resistant hypertension and merits further evaluation in prospective studies.
Unusual spindle cell tumours at the base of tongue (solitary fibrous tumour and malignant fibrous histiocytoma): report of two cases and review of literature
Authors: Dhingra S. , Mohindra S. , Vaiphei K. 
Published: March 2012

AbstractObjective:  Two cases of rare spindle cell tumours of the tongue are described. Solitary fibrous tumour is a mesenchymal neoplasm which is usually benign and malignant fibrous histiocytoma is a high grade aggressive sarcoma.Materials and methods:  Two patients presented to us with a mass at the base of the tongue. It is essential to keep tumours such as SFT and MFH in the differential diagnosis of lesions at the tongue base.Results:  Histological similarities with other soft tissue tumours may present as a diagnostic challenge and immunohistochemistry plays a pivotal role to clinch the diagnosis.Conclusion:  Surgical excision is the treatment of choice as they respond poorly to radiotherapy.
Milkweed loss in agricultural fields because of herbicide use: effect on the monarch butterfly population
Authors: PLEASANTS JOHN M. , OBERHAUSER KAREN S. 
Published: March 2012

Abstract.  1. The size of the Mexican overwintering population of monarch butterflies has decreased over the last decade. Approximately half of these butterflies come from the U.S. Midwest where larvae feed on common milkweed. There has been a large decline in milkweed in agricultural fields in the Midwest over the last decade. This loss is coincident with the increased use of glyphosate herbicide in conjunction with increased planting of genetically modified (GM) glyphosate‐tolerant corn (maize) and soybeans (soya).2. We investigate whether the decline in the size of the overwintering population can be attributed to a decline in monarch production owing to a loss of milkweeds in agricultural fields in the Midwest. We estimate Midwest annual monarch production using data on the number of monarch eggs per milkweed plant for milkweeds in different habitats, the density of milkweeds in different habitats, and the area occupied by those habitats on the landscape.3. We estimate that there has been a 58% decline in milkweeds on the Midwest landscape and an 81% decline in monarch production in the Midwest from 1999 to 2010. Monarch production in the Midwest each year was positively correlated with the size of the subsequent overwintering population in Mexico. Taken together, these results strongly suggest that a loss of agricultural milkweeds is a major contributor to the decline in the monarch population.4. The smaller monarch population size that has become the norm will make the species more vulnerable to other conservation threats.
Can Handheld Dynamometers Diagnose Partial-thickness Rotator Cuff Tears?
Authors: Millican Jared P. , Murrell George A. C. 
Published: March 2012

Background Partial tears of the rotator cuff tendons of the shoulder are a common cause of significant pain and disability, yet are difficult to diagnose clinically. Handheld dynamometry has demonstrated good sensitivity and specificity in the diagnosis of full-thickness rotator cuff tears. The present study aimed to determine whether handheld dynamometer measurements could predict the presence of a partial-thickness rotator cuff tear among patients with shoulder pain. Methods Handheld dynamometer measurements and signs of impingement were collected before surgical evaluation in 450 patients with a partial-thickness rotator cuff tear ( n = 150), full-thickness rotator cuff tear ( n = 150) or nonrotator cuff pathology ( n = 150). Results Patients with partial-thickness tears did not have significantly different strength compared to patients without rotator cuff tears. Patients with full-thickness tears had a decrease in abduction and external rotation strength ( p < 0.001). Patients with any rotator cuff tear were more likely to have signs of impingement during internal rotation ( p < 0.001) and impingement during external rotation ( p = 0.004). Conclusions Handheld dynamometer measurements were unable to reliably distinguish patients with partial-thickness rotator cuff tears from patients with other causes of shoulder pain. The abduction and external rotation muscle strength tests demonstrated their usefulness when distinguishing partial-thickness rotator cuff tears from full-thickness rotator cuff tears.

Published: March 2012

Background Management of degenerate rotator cuff tears associated with subacromial impingement is debatable. Methods We performed a prospective, randomised controlled trial to assess the efficacy of arthroscopic subacromial decompression (ASD) with or without repair of the rotator cuff using a mini-open technique. Results 42 patients (29 males and 13 females) with a mean age of 64 years (range 54–77 years) were recruited. 25 patients underwent ASD and cuff repair using mini-open technique whereas 17 patients had only ASD alone. All the patients were followed for a minimal of 1 year post-operatively. At final follow-up the mean Constant scores and patient satisfaction scores were not different between the groups (p value 0.06 and 0.44 respectively). The mean DASH scores were marginally significant (p value 0.05) and mean ASES scores were significant (p value 0.03). A 38% cuff rerupture rate was noted in the cuff repair group. Conclusions Our study demonstrates that in short-term the results of ASD with or without rotator cuff repair are not significantly different, however positive trends were noted in the cuff repair group. Although a significant rerupture rate was noted (38%) this had little effect on the outcome.
Detection of Oocyst‐Associated Toxoplasmosis in Swine from Southern Chile
Authors: Muñoz‐Zanzi C. , Tamayo R. , Balboa J. , Hill D. 
Published: March 2012

SummaryPork has been traditionally considered an important source of human Toxoplasma gondii infection. Pigs, as other meat‐producing animals, can become infected by the ingestion of oocysts that are shed in the environment by infected cats or by the consumption of cysts present in tissues of infected mammals, commonly small rodents. The objective of this study was to investigate the level of T. gondii infection in swine from southern Chile that can be associated with the ingestion of oocysts and therefore exposure to a contaminated environment. A total of 340 serum samples from swine were obtained from three commercial slaughterhouses located in the Araucania and Los Rios Regions from southern Chile. Study animals originated from local farms, mainly small commercial producers, and the meat is sold locally. Overall, 8.8% (30/340) of the samples showed T. gondii‐specific IgG antibodies. Of these sero‐positive animals, 80% (24/30) were also positive for antibodies specific against the oocyst stage of the parasite, indicating that animals had been infected recently by the ingestion of oocysts. The observed results suggest a high level of environmental contamination with oocysts on the farms of origin. In addition to the food safety problems associated with the consumption of meat from infected animals, the high level of environmental contamination on the farm represents a direct health risk for people living and/or working on these farms. Consequently, there is a need to develop on‐farm monitoring programmes and identify risk reduction strategies (food storage, water purification, rodent control and contact with cats) that are appropriate and cost‐effective for informal and outdoor type of farms.
Self‐Service Operations at Retail Stores: The Role of Inter‐Customer Interactions
Authors: Li Mei , Choi Thomas Y. , Rabinovich Elliot , Crawford Aaron 
Published: March 2012

Inter‐customer interactions are important to the operation of self‐services in retail settings. More specifically, when self‐service terminals are used as part of customers’ checkout processes in retail operations without the explicit involvement of retailers as the direct service providers, inter‐customer interactions become a significant managerial issue. In this article, we examine the impact of inter‐customer interactions at retail self‐service terminals on customers’ service quality perceptions and repeat purchase intentions at retail stores. We conduct a scenario‐based experimental design ( N = 674) using a 2 × 2 factorial design in which inter‐customer interactions are divided into “positive” vs. “negative” and occur during the “waiting” or during the actual “transaction” stages of self‐services at a retail store. We use attribution theory to develop the hypotheses. The results demonstrate that, through their interactions, fellow customers can exert influences on a focal customer's quality perceptions and repeat purchasing intentions toward a retail store. Furthermore, these influences were impacted by how customers attribute blame or assign responsibility toward the retail store. Service operations managers should leverage these interactions by designing into self‐service settings the capacities and interfaces that are best suited for customers’ co‐production of their self‐service experiences.
Misbehaviour in Pony Club horses: Incidence and risk factors
Authors: BUCKLEY P. , MORTON J. M. , BUCKLEY D. J. , COLEMAN G. T. 
Published: March 2012

SummaryReasons for performing study: Horse misbehaviour is an important cause of poor performance in Pony Club horses, is associated with horse‐related rider injuries and has been implicated as a nonspecific presenting sign for musculoskeletal pain. Despite this, little is known about the incidence of and risk factors for misbehaviour in Pony Club horses.Objective: This study aimed to describe the incidence and types of misbehaviour in a cohort of Pony Club horses and to identify risk factors for misbehaviour during riding.Methods: A prospective longitudinal study was conducted with 84 Pony Club horses from 41 families belonging to 7 Pony Clubs in one inland region of Australia. Owners recorded misbehaviour events and kept daily records of horse housing, exercise, nutrition, healthcare and disease status. Horses were subjected to a monthly veterinary examination. Descriptive statistics were calculated to describe the incidence of misbehaviour, and multivariable logistic regression was used to assess putative risk factors.Results: Misbehaviour during riding occurred on 3% of days when horses were ridden. On 52% of days with misbehaviour, the misbehaviour was classified as dangerous. Risk of misbehaviour was independently increased on exercise days when the horse was competing, and in months when the horse was fat or obese, fed supplementary feed daily, grazed on paddocks with >50% of ground cover as green grass, exercised on 5 days per month or less, and ridden for a total of 12 h or more in the month. No significant relationship was detected between misbehaviour and back pain.Conclusions: In populations such as the study population the risk of misbehaviour is higher in fatter horses, in horses with access to pastures with greater green grass cover, in those fed daily supplements, in horses receiving exercise less frequently, and during competition.Potential relevance: These results highlight the importance of considering horse body condition, nutrition and exercise in any investigation of horse misbehaviour. In addition, recommendations based on these results could be used by veterinarians assisting horse owners to prevent misbehaviour. From the perspective of recreational horse owners, behaviour is a key determinant of horse performance.
Lagrangian displacement tracking using a polar grid between endocardial and epicardial contours for cardiac strain imaging
Authors: Ma Chi , Varghese Tomy 
Published: March 2012

Purpose:Accurate cardiac deformation analysis for cardiac displacement and strain imaging over time requires Lagrangian description of deformation of myocardial tissue structures. Failure to couple the estimated displacement and strain information with the correct myocardial tissue structures will lead to erroneous result in the displacement and strain distribution over time.Methods:Lagrangian based tracking in this paper divides the tissue structure into a fixed number of pixels whose deformation is tracked over the cardiac cycle. An algorithm that utilizes a polar‐grid generated between the estimated endocardial and epicardial contours for cardiac short axis images is proposed to ensure Lagrangian description of the pixels. Displacement estimates from consecutive radiofrequency frames were then mapped onto the polar grid to obtain a distribution of the actual displacement that is mapped to the polar grid over time.Results:A finite element based canine heart model coupled with an ultrasound simulation program was used to verify this approach. Segmental analysis of the accumulated displacement and strain over a cardiac cycle demonstrate excellent agreement between the ideal result obtained directly from the finite element model and our Lagrangian approach to strain estimation. Traditional Eulerian based estimation results, on the other hand, show significant deviation from the ideal result. Anin vivo comparison of the displacement and strain estimated using parasternal short axis views is also presented.Conclusions:Lagrangian displacement tracking using a polar grid provides accurate tracking of myocardial deformation demonstrated using both finite element andin vivo radiofrequency data acquired on a volunteer. In addition to the cardiac application, this approach can also be utilized for transverse scans of arteries, where a polar grid can be generated between the contours delineating the outer and inner wall of the vessels from the blood flowing though the vessel.
Voce voco. Ariadne in Ovids Heroides und die ‘weibliche’ Stimme
Authors: Pieper Christoph 
Published: March 2012

Abstract
The article analyses how Ovid in the 10th letter of his Heroides experiments with the concept of a female voice within Roman literature. Ovid constructs Ariadne as a literary speaker against the background of (1) the Augustan elegiac tradition with its mostly male speakers, (2) the earlier phases of the Ariadne-myth in which Ariadne’s fate is determined by men (Theseus and Bacchus), and (3) the reception of this myth in Catullus’ famous ecphrasis in carmen 64. In the beginning of Heroides 10, Ovid shows how Ariadne develops consciousness of her own ability to speak. She develops from a heterodiegetic (epic) narrator to a homodiegetic (elegiac) speaker. In a second step, however, Ovid demonstrates that Ariadne is not only generally inexperienced in the field of literature, but that her attempt to re-shape her own story from a female perspective must necessarily fail. Her literary character cannot be separated from the previous (male) myth. At the end of the letter, she accepts her own literary immaturity when she asks Theseus to be the future narrator of her own fate. By showing that Ovid in his Ariadne-letter actually stages the failure of his protagonist’s attempt to free herself from a male literary tradition, I suggest that the Heroides should not be read as female literature, but as texts which reaffirm male dominance within Roman literary society.
Marriage and Divorce for the Sake of Religion: The Marital Life of Cadari in Indonesia 1
Authors: Nisa Eva F. 
Published: March 2012

AbstractThe religious transformation experienced bycadari(face-veiled women) in Indonesia belonging to two revivalist movements, Tablighi Jamāʿat and Salafism, has propelled them to change their habitus. The nature of their new pious habitus has shaped the life of these women including their marital life. The embodiment of this pious habitus can be seen in practices related to marriage ranging from choice of marriage partner, interactions with marriage partner, new marriage practices (arranged marriage, early marriage and mass marriage) and termination of marriage. All of these can be regarded as their efforts to construct a pious self and an ideal Islamic family,keluarga sakinah(harmonious family). Since religious doctrines are very important in the life of thecadari, religious homogamy is a crucial aspect in their decision to get married or divorced. While there are some studies on the importance of religious homogamy in sustaining marital satisfaction and stability, the experiences of women in such marriages has often been neglected. This article focuses on the importance of religious homogamy by listening to the experiences ofcadariwomen.
On Twenty-First Century Social Transformation: Class, Nation, Gender and Race in a Period of Revolution and Capitalist Crisis
Authors: Brewer Rose M. 
Published: March 2012

Abstract
This article is an analysis of the Black liberation struggle in the context of current capitalist crisis. The past forty-plus years since 1968 is the periodization embodied in this framework. The analysis is partially a rumination on the current state of Black America and the Black liberation struggle. Some discussion of an emergent black left and the United States Social Forum as a process for social transformation is considered. It is, as well, a look into Black feminist interventions in the Black freedom struggle. Core here is the feminist demand to center race, class, gender in intersectionality. Finally, some thought is given to the interplay and complexities surrounding class and the Black right in the US with implications for the current period.
New Perspectives on Rosa Luxemburg’s Critique of Global Capitalism
Authors: Hudis Peter 
Published: March 2012

AbstractThe global economic-financial downturn has given new impetus to a re-examination of Rosa Luxemburg’s writings on capitalist accumulation and economic crisis, which pinpointed the central contradiction of capitalism in its drive for global expansion. In this article I critically engage Luxemburg’s theory of capital accumulation and crisis by evaluating it in comparison with the central categories of Volumes One and Two of Marx’sCapitalon the one hand, and the quest for an alternative to capitalism in the twenty-first century on the other. I argue that Marx’s procedure in Volume Two ofCapital, in which he abstracts from realization crises and foreign trade in order to discern the “law of motion” of capital freed from secondary and tertiary considerations, captures the internal dynamic of capitalist development and crises far better than its Keynesian and neo-Keynesian alternatives.
The Wealth (and Want) of Nations: The Impact of Economic Globalization on the Developing World
Authors: Haase Dwight 
Published: March 2012

AbstractIn this article I review the literature on four outcomes of economic globalization: growth, wages, poverty, and inequality. Special attention is given to the importance of these outcomes for people of developing nations. Findings in the literature show a correlation between economic globalization and economic growth, but the relationship is much stronger for some nations than for others. Evidence on wages also shows uneven benefits from economic globalization. The evidence on poverty is inconclusive, while several authors note growing inequality within nations. These studies highlight the need for more research that includes extraneous factors, such as foreign aid and remittances. Further research also should refine the unit of analysis and gather extensive data from the informal sector.
