Published: March 2013

The ca. 620 Ma Huntington Mountain pluton and East Bay Hills Group, which comprise part of the Avalonian Mira terrane, Cape Breton Island, Nova Scotia, Canada, are characterized by pervasive propylitic alteration (chlorite, epidote, sericite, and Fe-Ti oxides) and low δ18O values (–3.8 to +6.2‰). This alteration is a product of interaction with hydrothermal fluids of meteoric and/or meteoric-seawater mixed origin at ~300 °C over a range of water/rock (w/r) ratios. Locally, the propylitic alteration was further overprinted by quartz-calcite-sericite alteration. Such samples have generally higher δ18OWR values (up to +9.5‰), reflecting interaction with evolved meteoric water at lower temperatures (~200 °C) and very low w/r ratios. The hydrothermal fluids responsible for widespread propylitic alteration of the Huntington Mountain-East Bay Hills complex (and regions beyond) likely entered the crust during initial rifting of the Mira terrane from Gondwana at ca. 575–550 Ma.RÉSUMÉLe pluton du mont Huntington, apparu il y a quelque 620 Ma et la succession volcanique des collines East Bay, qui font partie du terrane Mira d’Avalon, sur l’île du Cap-Breton, en Nouvelle-Écosse, au Canada, se caractérisent par une altération propylitique envahissante (chlorite, épidote, séricite, et oxydes de fer et de titane), et des teneurs faibles en δ18O (−3,8 à +6,2‰). Cette altération est le résultat de l’interaction de fluides hydrothermaux d’origine mixte météorique ou météorique et d’eau de mer, ou des deux, à une température d’environ 300 °C, selon divers rapports eau/roche. Au plan local, une altération de quartz-calcite-séricite s’est superposée à l’altération propylitique. Ces échantillons ont en règle générale des valeurs de δ18OWR supérieures (qui peuvent atteindre +9,5‰), ce qui rend compte de l’interaction de l’eau météorique évoluée à de basses températures (environ 200 °C) et de rapports eau/roche très faibles. Les fluides hydrothermaux à l’origine de l’altération propylitique très étendue du complexe du mont Huntington et des collines East Bay (et des régions au-delà) ont probablement pénétré la croûte terrestre au cours du soulèvement initial du terrane Mira, à l’époque du continent de Gondwana, il y a de cela entre 575 et 550 Ma.[Traduit par la redaction]
Productivity Analysis in Power Generation Plants Connected to the National Grid: A New Case of Bio Economy in Nicaragua
Authors: Blanco-Orozco N. V. , Zúniga-González C. A. 
Published: March 2013

The purpose of this paper was to study the productivity where renewable energy resources and non-renewable resources for generating electricity in power plants connected to the national grid of Nicaragua were used. This article analyzed the total factor productivity of Bioeconomy for the generation of electricity from plants using sugarcane bagasse (biomass) as a renewable resource and petroleum. The data envelopment analysis (DEA) and the Malmquist index were used to measure the total factor productivity of power generation utilities connected to the national grid of Nicaragua. The results obtained by comparing sugar mills connected to the SIN was that Monte Rosa mill has a higher rate of increase in productivity due to the change of total factor productivity and when comparing thermal plants that employ petroleum products in power generation, the more efficient were ALBANISA, GECSA and TIPITAPA POWER; but when comparing thermal plants and some using renewable energy San Antonio sugar mill and ALBANISA were more efficient.

Published: March 2013

Purpose We report a rare case of acute postoperative Staphylococcus schleiferi endophthalmitis following an uneventful cataract extraction. Methods An 83-year-old woman underwent uneventful phacoemulsification without receiving the usual intracameral cefuroxime solution due to cephalosporin intolerance. Two days postoperatively, she presented with acute ocular pain and blurred vision in the operated eye. Ophthalmic examination revealed signs of acute keratitis and endophthalmitis. Corneal scrapes and vitreous taps were sent for cultivation and analysis. The patient received intravitreal antibiotics at the same time. Results Cultivation grew S schleiferi, a pathogen commonly found in dogs. Following microbiological report, the patient received a repeated intravitreal injection of 1 mg/0.1 mL vancomycin combined with fortified topical vancomycin drops. One week later, the inflammation subsided completely while the corneal ulcer healed and visual acuity improved dramatically. Further examination revealed the existence of the same pathogen in a specimen obtained from the dog owned by the patient's family. Conclusions This description of S schleiferi endophthalmitis highlights the need to provide alternative intracameral antibiotic solution in the operating room and avoid direct contact with dogs during the first postoperative period after intraocular surgery.
Treatment of Macular Edema Associated with Retinal vein Occlusion Using Sustained-release Dexamethasone Implants in a Clinical Setting
Authors: Merkoudis Nikolaos , Granstam Elisabet 
Published: March 2013

Purpose To evaluate the clinical effect, safety, and administration procedure of slow-release dexamethasone implants (Ozurdex®) for macular edema secondary to retinal vein occlusion in clinical praxis. Methods Data from 11 patients (4 eyes with central vein occlusion and 7 eyes with branch vein occlusion) were reviewed. Data were compiled and analyzed with respect to best-corrected visual acuity (BCVA), central macular thickness (CMT), intraocular pressure (IOP), and adverse events. Follow-up was 10 months. Changes in BCVA ≥ logMAR 0.2, IOP ≥5 mm Hg, and CMT ≥100 μm were considered clinically relevant. Results Two months after the first dexamethasone implant, BCVA improved from logMAR 0.65 ± 0.2 to logMAR 0.34 ± 0.1. All patients demonstrated a decrease in CMT from an initial average value of 632 ± 178 μm to 229 ± 34 μm. However, in 10 out of 11 eyes, macular edema recurred by month 4 through 5 and a second dexamethasone implant was administered. Two and 4 months after the second implant, BCVA was logMAR 0.36 ± 0.2 and logMAR 0.40 ± 0.2 and the CMT was 254 ± 61 μm and 357 ± 81 μm, respectively. The IOP increased 5.1 ± 1.5 mm Hg 1 month after the first implant compared to baseline. In eyes with an IOP above 25 mm Hg (4 out of 11), pressure-lowering eyedrops were administered. Conclusions Administration of dexamethasone implants induced a clinically relevant increase in visual acuity and a decrease in central macular thickness. In 91% of patients, macular edema recurred within 5 months and a second implant was administered. Adverse events, primarily increased IOP, were manageable. The injection procedure was relatively simple and uncomplicated.

Published: March 2013

Purpose To describe 3 cases of ectopia lentis (EL) associated with primary congenital glaucoma (PCG) and differentiate between primary and secondary EL regarding pathogenesis. Methods We reviewed the clinical charts of 3 children previously diagnosed with congenital glaucoma who developed secondary EL. The following points were noted: medical and surgical history, refraction, keratometry, corneal diameter, axial length (AL), intraocular pressure, and cup/disc ratio. Results The 3 patients were respectively aged 12, 3, and 4 months. A trabeculectomy was performed in both eyes at 1-week interval in all cases. The EL was noted during follow-up controls. Lensectomy/vitrectomy was performed in 2 patients, in case of high astigmatism (>5.00 D) and/or the lens border visible in the pupillary area. Postoperative refraction was hyperopic. Conclusions Ectopia lentis secondary to PCG should be differentiated from primary EL regarding pathogenesis. Anterior segment distension appears to be the principal mechanism in these cases. Postoperative hyperopia is observed despite the increased AL secondary to PCG. These biometric results are due to global distension of the globe, which also flattens the cornea with consequently lower refractive effect.
Circular and temporary migration regimes and their implications for family
Authors: Wickramasekara Piyasiri 
Published: March 2013

AbstractThe focus on migrant workers in discussions of international migration has tended todetract attention from the role of migrant families. There is consensus that family unificationis important for migrants because it helps to promote their effective integration in hostcountries. Further, family fragmentation has adverse impacts on all family members, and there isconsiderable research to show that the social cost of migration on families left behind, especiallychildren, can be high. Different migration regimes and policies have different implications for theunity and integrity of migrant families. This paper considers the implications of circular migrationregimes (which have become increasingly popular in the discourse on international migrationand development) for migrant families.
Child migrants in the labour market: Not a good deal for them or their families
Authors: Glind Hans van de 
Published: March 2013

AbstractAround the world, millions of children are migrating, both within and between countries—a
significant number with their families, others alone. They are part of large-scale population
movements currently taking place in many parts of the world. These broader population
movements include an estimated 214 million international migrants (Zukang, 2009) and 740
million internal migrants (UNDP, 2009).In the coming years an unprecedented number of young people are expected to migrate and
shift population dynamics further. They’ll be driven by demographic factors, perceived economic
disparity, youth unemployment [ILO estimated youth unemployment of over 80 million in 2010
(ILO, 2010a)], violent conflict and state failure, natural disasters, and environmental issues.
The gender-migration-employment nexus
Authors: Piper Nicola 
Published: March 2013

AbstractThis paper discusses how migration impacts families—from the specific perspective of
gender in the context of employment. I shall give particular attention to those migrants who
end up working in low-skilled, low-paid jobs in destination countries. Gender is treated here
as a relational concept, comparing not only male migrants to female migrants, but exploring
relations between generations (parents, children, grandparents), employer and worker, based on
socially constructed understandings of specific roles and patterns of behavior according to sex,
generational standing and socio-economic status. When a gender dimension is incorporated into
the analysis, it also brings to the fore the social dimensions of the issues under debate.I start this paper by outlining the main analytical framework used for the analysis of
the issue of gendered labour migration, which is based on establishing a link between three
feminisations—of poverty, work and migration—thus addressing the causes and consequences
of migration, posing the question of what the implications of the three feminisations are for
gender and family relations more broadly (dealt with in section II). The final section outlines the
main rights issues and makes suggestions for policy intervention.
Refugees and migration: Local governance, challenges and responses in the city of Johannesburg, South Africa
Authors: Zwane Wandile 
Published: March 2013

AbstractThe paper draws from the experiences of the City of Johannesburg, South Africa, to examine
the way an emerging democracy can on one hand respond to the challenges faced by the families
of its own citizens and on the other hand those faced by the migrant community. It further
looks at the costs of not prioritising the needs of the migrant families and the manner in which
community integration strategies can assist migrant communities to confront some of the
challenges facing their families.
“Thinking globally, acting locally.” Children left-behind: Their experience in the Americas
Authors: Cruz Victoria 
Published: March 2013

Transcript of lecture given 28 March 2012To begin, it is no coincidence that this week a meeting of the Regional Conference on
Migration—which brings together countries from Central and North America—is being held in
San Jose, Costa Rica. This meeting is specifically titled “Children and adolescents, migration and
refugees,” and central to this topic are child trafficking, child-migrant smuggling, the migration of
unaccompanied children and other issues associated with migration in transit and destination
countries. Although many of the countries participating in this conference are countries of
origin of migration, the plight of those “left behind” in their home communities is not part of the
agenda.Likewise, if you run a search for information on ‘children left behind’ and ‘migration,’ you
will find that, at least in the Latin American region, the subject has not been widely researched,
and existing analyses are done along the same lines as migration; that is, it is analyzed from
the perspective of movements among countries of transit and destination without taking the
countries of origin into consideration. This is not surprising considering that the more developed
the destination site is (where more employment sources and access to other services exist),
the more relevant the migration paths leading there (mainly international ones) will be, with
home communities remaining less visible, and often forgotten. In other words, to talk about the
children left behind is a challenge and will remain so until the issue is placed squarely in the
debate about migration.
Family, Migration and Dignity: An Introduction
Authors: Mesdoua Amina , Taran Patrick 
Published: March 2013

AbstractMore than 214 million people live outside their countries of origin or citizenship today.
Among these, 105 million men and women are economically active , contributing to development,
economic progress and social welfare in origin and destination countries alike. It is estimated
that a similar number comprise children and other dependents accompanying working migrants.
However, many migrant workers have to leave husbands or wives and children “back home” in
order to work abroad to provide for their families. In some cases, both parents go abroad to work
because there are no possibilities for decent work at home, leaving care of children in the hands
of others.
The circumstances of migration today pose multiple challenges to family as the core cultural,
social, and economic unit in society, and to preparing the next generations for the world of work.
Welcoming statement

Excellencies, distinguished guests,Ladies and gentlemen,What an honor and pleasure it is to welcome you all to this symposium on Family, Migration
and Dignity. As we are going to address the challenges and harness the benefits associated with
international migration, it gives me pleasure to see such a diverse audience gathered in this
room. I would also like to extend a warm welcome to the speakers. Thank you for agreeing to
share your knowledge and perspectives on this important topic.The Mission of the Doha International Institute for Family Studies and Development is to
encourage, support and promote implementation of the Doha Declaration on the family of 2004,
and to reaffirm international commitments to strengthen the family. At DIIFSD, we consider that
policy making whether at the national, regional or international levels frequently ignores the
contribution that the family as a unit can leverage in achieving development objectives at all
levels.
Discriminatory Policies & Practices Intersectionality: The Promise & the Challenge
Authors: Clark Sevda 
Published: March 2013

A StoryOn one of my trips abroad I found myself in transit at Amsterdam airport. It is not an
enjoyable experience (to say the least) on the best of flights, but this one experience will be
one I continue to remember with a mixed sense of pain and disillusionment. Airport security
controls are not something unfamiliar to me, and again, I braced myself as I carefully unpacked
the dubious objects from my handbag—a clear plastic bag containing my lip gloss, perfume and
anti-bacterial lotion among other indispensable items, as well as my laptop. I don’t remember
‘beeping’ as I walked through the security gate. Yet, I was hailed to step aside by a female customs
officer who had been deemed as appropriate to physically examine my body—rub it from head
to toe to ensure that I had not carefully strapped any explosive devices to my admittedly fitted
clothing. She looked noticeably indignant, and she made no attempt to hide her scorn. I breathed
deeply and walked into the curtained area where I was to be further examined. I had the sense
that I was in for something different this time. The whole time, the power dynamics that were at
play were so thick that they almost took on a presence of their own.
Direct Photopatterning of Electrochromic Polymers
Authors: Jensen Jacob , Dyer Aubrey L. , Shen D. Eric , Krebs Frederik C. , Reynolds John R. 
Published: March 2013

AbstractPropylenedioxythiophene (ProDOT) polymers are synthesized using an oxidative polymerization route that results in methacrylate substituted poly(ProDOTs) having a Mn of 10–20 kDa wherein the methacrylate functionality constitutes from 6 to 60% of the total monomer units. Solutions of these polymers show excellent film forming abilities, with thin films prepared using both spray‐casting and spin‐coating. These polymers are demonstrated to crosslink upon UV irradiation at 350 nm, in the presence of an appropriate photoinitiator, to render the films insoluble to common organic solvents. Electrochemical, spectroelectrochemical, and colorimetric analyses of the crosslinked polymer films are performed to establish that they retain the same electrochromic qualities as the parent polymers with no detriment to the observed properties. To demonstrate applicability for multi‐film processing and patterning, photolithographic patterning is shown, as is desired for fully solution processed and patterned devices.
Energetics of Donor‐Doping, Metal Vacancies, and Oxygen‐Loss in A‐Site Rare‐Earth‐Doped BaTiO3

Published: March 2013

AbstractThe energetics of La‐doping in BaTiO3 are reported for both (electronic) donor‐doping with the creation of Ti3+ cations and ionic doping with the creation of Ti vacancies. The experiments (for samples prepared in air) and simulations demonstrate that ionic doping is the preferred mechanism for all concentrations of La‐doping. The apparent disagreement with electrical conduction of these ionic doped samples is explained by subsequent oxygen‐loss, which leads to the creation of Ti3+ cations. Simulations show that oxygen‐loss is much more favorable in the ionic‐doped system than undoped BaTiO3 due to the unique local structure created around the defect site. These findings resolve the so‐called “donor‐doping” anomaly in BaTiO3 and explain the source of semiconductivity in positive temperature coefficient of resistance (PTCR) BaTiO3 thermistors.
Hyperphagia, Mild Developmental Delay But Apparently No Structural Brain Anomalies in a Boy Without SOX3 Expression

Published: March 2013

AbstractThe transcription factor SOX3 is widely expressed in early vertebrate brain development. In humans, duplication of SOX3 and polyalanine expansions at its C‐terminus may cause intellectual disability and hypopituitarism. Sox3 knock‐out mice show a variable phenotype including structural and functional anomalies affecting the branchial arches and midline cerebral structures such as the optic chiasm and the hypothalamo‐pituitary axis. SOX3 is claimed to be required in normal brain development and function in mice and humans, as well as in pituitary and craniofacial development. We report on an 8‐year‐old boy with a 2.1 Mb deletion in Xq27.1q27.2, which was found to be inherited from his healthy mother. To our knowledge, this is the smallest deletion including the entire SOX3 gene in a male reported to date. He is mildly intellectually disabled with language delay, dysarthria, behavior problems, minor facial anomalies, and hyperphagia. Hormone levels including growth, adrenocorticotropic and thyroid stimulating hormones are normal. Magnetic resonance imaging (MRI) at age 6 years showed no obvious brain anomalies. Genetic redundancy between the three members of the B1 subfamily of SOX proteins during early human brain development likely explains the apparently normal development of brain structures in our patient who is nullisomic for SOX3. © 2013 Wiley Periodicals, Inc.
Selective Semihydrogenation of Alkynes on Shape‐Controlled Palladium Nanocrystals

Published: March 2013

AbstractA systematic study on the selective semihydrogenation of alkynes to alkenes on shape‐controlled palladium (Pd) nanocrystals was performed. Pd nanocrystals with a cubic shape and thus exposed {100} facets were synthesized in an aqueous solution through the reduction of Na2PdCl4 with L‐ascorbic acid in the presence of bromide ions. The Pd nanocubes were tested as catalysts for the semihydrogenation of various alkynes such as 5‐decyne, 2‐butyne‐1,4‐diol, and phenylacetylene. For all substrates, the Pd nanocubes exhibited higher alkene selectivity (>90 %) than a commercial Pd/C catalyst (75–90 %), which was attributed to a large adsorption energy of the carbon–carbon triple bond on the {100} facets of the Pd nanocubes. Our approach based on the shape control of Pd nanocrystals offers a simple and effective route to the development of a highly selective catalyst for alkyne semihydrogenation.
