Objectives. Although eye injuries are common among citrus harvesters, the proportion of workers using protective eyewear has been negligible. We focused on adoption of worker-tested safety glasses with and without the presence and activities of trained peer-worker role models on harvesting crews.Methods. Observation of 13 citrus harvesting crews established baseline use of safety eyewear. Nine crews subsequently were assigned a peer worker to model use of safety glasses, conduct eye safety education, and treat minor eye injuries. Safety eyewear use by crews was monitored up to 15 weeks into the intervention.Results. Intervention crews with peer workers had significantly higher rates of eyewear use than control crews. Intervention exposure time and level of worker use were strongly correlated. Among intervention crews, workers with 1 to 2 years of experience (odds ratio [OR] = 2.89; 95% confidence interval [CI] = 1.11, 7.55) and who received help from their peer worker (OR = 3.73; 95% CI = 1.21, 11.57) were significantly more likely to use glasses than were other intervention crew members.Conclusions. Adaptation of the community health worker model for this setting improved injury prevention practices and may have relevance for similar agricultural settings.

Objectives. We developed and assessed AMIGAS (Amigas, Mujeres Latinas, Inform andonos, Gui andonos, y Apoy andonos contra el SIDA [friends, Latina women, informing each other, guiding each other, and supporting each other against AIDS]), a culturally congruent HIV prevention intervention for Latina women adapted from SiSTA (Sistas Informing Sistas about Topics on AIDS), an intervention for African American women.Methods. We recruited 252 Latina women aged 18 to 35 years in Miami, Florida, in 2008 to 2009 and randomized them to the 4-session AMIGAS intervention or a 1-session health intervention. Participants completed audio computer-assisted self-interviews at baseline and follow-up.Results. Over the 6-month follow-up, AMIGAS participants reported more consistent condom use during the past 90 (adjusted odds ratio [AOR] = 4.81; P < .001) and 30 (AOR = 3.14; P < .001) days and at last sexual encounter (AOR = 2.76; P < .001), and a higher mean percentage condom use during the past 90 (relative change = 55.7%; P < .001) and 30 (relative change = 43.8%; P < .001) days than did comparison participants. AMIGAS participants reported fewer traditional views of gender roles (P = .008), greater self-efficacy for negotiating safer sex (P < .001), greater feelings of power in relationships (P = .02), greater self-efficacy for using condoms (P < .001), and greater HIV knowledge (P = .009) and perceived fewer barriers to using condoms (P < .001).Conclusions. Our results support the efficacy of this linguistically and culturally adapted HIV intervention among ethnically diverse, predominantly foreign-born Latina women.
Winning Policy Change to Promote Community Health Workers: Lessons From Massachusetts in The Health Reform Era
Authors: Mason Terry , Wilkinson Geoffrey W. , Nannini Angela , Martin Cindy Marti , Fox Durrell J. , Hirsch Gail 
Published: October 2011

There is a national movement among community health workers (CHWs) to improve compensation, working conditions, and recognition for the workforce through organizing for policy change. As some of the key advocates involved, we describe the development in Massachusetts of an authentic collaboration between strong CHW leaders of a growing statewide CHW association and their public health allies. Collaborators worked toward CHW workforce and public health objectives through alliance building and organizing, legislative advocacy, and education in the context of opportunities afforded by health care reform. This narrative of the path to policy achievements can inform other collaborative efforts attempting to promote a policy agenda for the CHW workforce across the nation.

Leontodon saxatilis Lam.: a range-expanding plant or a poorly recognized species in Poland?
Until 2001, Leontodon saxatilis was known in Poland almost exclusively from the north-west part. However, numerous localities of the species in southern Poland were reported in recent publications and recorded in our field studies. Data on the distribution and habitat preferences of L. saxatilis at the new localities are presented and its origin in southern Poland is discussed.

Common fixed point theorems for occasionally converse commuting mappings in symmetric spaces
Authors: Pathak HK , Verma RK 
Published: October 2011

In this paper, we introduce the notion of occasionally converse commuting (occ) mappings. Every converse commuting mappings ([1]) are (occ) but the converse need not be true (see, Ex.1.1-1.3). By using this concept, we prove two common fixed point results for a quadruple of self-mappings which satisfy an implicit relation. In first result one pair is (owc) [5] and the other is (occ), while in second result both the pairs are (occ). We illustrate our theorems by suitable examples. Since, there may exist mappings which are (occ) but not conversely commuting, the Theorems 1.1[2], 1.2[2] and 1.3[3] fails to handle those mapping pairs which are only (occ) but not conversely commuting (like Ex.1.4). On the other hand, since every conversely commuting mappings are (occ), so our Theorem 3.1 and 3.2 generalizes these theorems and the main results of Pathak and Verma [6]-[7] Mathematics Subject Classifications: 47H10; 54H25. Keywords and Phrases: commuting mappings; conversely commuting mappings; occasionally converse commuting (occ) mappings; set of commuting mappings; fixed point.

Efficacy of Papacarie for Caries Removal: An in vivo Study
Authors: Raj Sunil 
Published: October 2011

ABSTRACT

Objectives
Conventional caries removal is associated with unpleasant perception of drilling, requirement of local anesthesia, pressure effects on the pulp, etc. The chemomechanical method of caries removal has overcome these shortcomings. It is not only more comfortable to the patient but also preserves the healthy tissue. The present study was undertaken to evaluate and compare the time taken for caries removal, perception of pain and presence of secondary caries after a period of 10 months with Papacarie (Formulae One, Brazil 2003) and the conventional method. Bilateral primary molars in 52 children age ranging from 5-12 years were selected and divided into group I (conventional method) and group II (chemomechanical method) and compared.

Results
Mean time taken in the conventional method (14.5 ± 5.367 sec) was significantly higher than papain gel (11.2 ± 5.959 secs). The pain score in group 1 was significantly higher than in group 2. The pain experienced in the conventional method ranged from a minimum of 0 (none) to a maximum of 4 (uncomfortable). Whereas in papain gel, it ranged from 0 (none) to 2 (annoying). The presence of secondary caries after a follow-up of 10 months was not statistically significant.

Conclusion
Papacarie method seems to be promising as an alternative treatment procedure in pediatric dentistry.

Authors: Praveen BN , Shubhasini AR , Vaseemuddin Syed , Amrutesh Sunita , Pal Sumona 
Published: October 2011

ABSTRACT

Objective
Though the soft palate presents with varied morphology, very few studies have described its diversity. The aim of our study was to investigate various shapes of soft palate in normal individuals.

Methods
The study comprised of 80 individuals requiring orthodontic treatment but without any speech abnormality, whose age ranged from 9 to 31 years. Velar shape was examined on digital lateral cephalograms and was allocated to one of the six patterns as described by You M et al. The difference in proportion of each type and also difference between genders were studied.

Results
The normal soft palate can be classified into six types based on its shape. Type 2—rat-tail shape is most common in both the genders. There is no significant difference in proportion of various shapes of soft palate between genders.

Conclusion
Soft palate may have variable morphology. Knowledge of varied spectrum of velar morphology may help in successful functional and structural repair in cleft palate cases, and shed some light towards the causes of obstructive sleep apnea and related disorders.

ABSTRACT
Over the years researchers have reported on the frequency and distribution of yeast in the oropharynx of apparently normal individuals and those with systemic or mycotic diseases wearing dentures. Few workers have taken into consideration the role played by the legion of denture base materials on the occurrence and progression of denture stomatitis. Hence this study was undertaken with the objective of evaluating the in vitro adherence of Candida albicans to different denture base materials namely reinforced polymethyl methacrylate, Nonreinforced polymethyl methacrylate and Cobalt chrome alloy of which chrome cobalt alloy showed less adherence to candidal cells compared to the two polymethyl methacrylate resins.

Published: October 2011

ABSTRACT
Teeth are vertebrate organs that arise from complex and progressive interactions between an ectoderm, the oral epithelium and an underlying mesenchyme. A significant amount of research has focused on determining the processes that initiate tooth development. It is widely accepted that there is a factor (multiple signaling molecules, including BMPs, FGFs, Shh and Wnt proteins) within the tissues of the first branchial arch that is necessary for the development of teeth. A 9-year-old reported to our department with the chief complaint of pain in the lower right back teeth region. On clinical examination, mandibular molars revealed the presence of an extra cusp on the lingual surface. Occurrence of six cusps in permanent mandibular molar is a rare phenomenon, and number of cases reported is very few.

ABSTRACTOligodontia, a form of hypodontia commonly seen in permanent than in deciduous dentition. It is defined as the congenital absence of six or more teeth, excluding third molars. It is relatively a rare condition that can occur either as an isolated finding or as part of a syndrome. A case of nonsyndromic oligodontia in a 12-year-old boy with congenital absence of all permanent teeth except the premolars (excluding third molars) and over-retained deciduous dentition with conical shaped anteriors is reported. The prevalence, possible etiological factors and treatment options of the condition is reviewed.

Authors: Kadagad Poornima , Umarani Meenaxi V , Pinto Pascal X 
Published: October 2011

ABSTRACT
Primitive neuroectodermal tumor (PNET) is an aggressive round cell malignancy of presumed neural crest origin belonging to Ewing's sarcoma family of tumors. Peripheral PNET is less common in head and neck region and only eight cases of primary PNET of maxilla have been reported. We report a case of 3-year-old boy diagnosed with PNET of maxilla based on detailed radiologic, histopathologic, and immunohistochemical studies. Though the imaging features of PNET are nonspecific and definitive diagnosis is only by immunohistochemistry, PNET should be included in the differential diagnoses of fast growing soft tissue tumors of children and young adolescents. We emphasize the need for its early diagnosis and prompt management owing to its aggressive nature and high mortality rate.
Sedimentations: Some Thoughts on Schoenberg’s Musical Accompaniment to a Cinematographic Scene
Authors: Ryan David 
Published: October 2011

This article examines Arnold Schoenberg’s Begleitmusik zu einer Lichtspielszene of 1930. This, essentially, is a soundtrack in search of a film (no film was actually created with it in mind), and clearly speaks of Schoenberg’s bleak premonitions of the coming decade with its cue titles of ‘threatening fear’ – ‘danger’ – and ‘catastrophe’. The article further explores Schoenberg’s music in relation to the musical/ cinematic practices of his day. This leads to a discussion of Jean-Marie Straub and Danielle Huillet’s utilization of the score from 1973 which uses film as a self-reflexive device to explore the personal, cultural and the political. Having received permission to create a new film for this piece (currently in planning) the author of this article hopes to explore how the cities of Vienna and Berlin might form a visual hinge through which to view the tumultuous exile of the composer from Vienna to Berlin and on to the USA after the rise of National Socialism in 1933. Like Straub and Huillet the author aims to use, and discuss, the potential of film to map the historical onto the present.
Across Cultural and National Borders: Diasporic Chinese Family in Pushing Hands
Authors: Han Qijun 
Published: October 2011

Being embedded in the interdisciplinary area of media and culture studies, this articlel explores the family melodrama in transnational Chinese cinema drawing upon theoretical discussions with regard to the historical emergence of melodrama in correspondence to, as Th. Elsaesser says, “periods of intense social and ideological crisis”. While serving as a reflection on the tension between tradition and modernity displayed in the domestic domain, Ang Lee’s Chinese-characterized family melodrama also illustrates the differences between Chinese and Hollywood family melodrama. Linked to the ongoing debate about “melodrama as a cross-cultural form”, in the process of analyzing the film text, our perceptions of generic dislocation or displacement, transcultural entanglements and globalization in light of contemporary cultural practices will be furthermore complicated.
Bioactive Materials for Regenerative Medicine: Zeolite‐Hydroxyapatite Bone Mimetic Coatings
Authors: Bedi Rajwant Singh , Chow Gabriel , Wang Junlan , Zanello Laura , Yan Yushan S. 
Published: October 2011

AbstractWe report the synthesis and characterization of a novel zeolite‐hydroxyapatite composite coating on titanium alloys and stainless steel. The zeolite‐hydroxyapatite coating is superhydrophilic and outperforms the state‐of‐the‐art Ti6Al4V alloys in corrosion resistance tests in aggressive pitting NaCl media, phosphate buffer solution with BSA protein, as well as highly complex DMEM cell culture media. And the composite coating also eliminates the elastic modulus mismatch between coating and bone. In addition, the composite coating has an osteoconductive and osteoinductive effect on hFOBs, indicating that it may enhance osteointegration of implants and speed up post‐surgical recovery, and thus reduce the need for recurring implant replacement surgeries. Replacing titanium with zeolite‐hydroxyapatite coated steel can also significantly reduce implant cost while improving implant lifespan.

Published: October 2011

AbstractIn this work, the impact of heat treatment on the real structure of Bi2Te3/Sb2Te3 multilayers is investigated. The material was heated in situ in the transmission electron microscope (TEM) and ex situ inside a furnace after preparing these layers with the so‐called nanoalloying deposition technique via molecular beam epitaxy (MBE) equipment. The samples were prepared as a lamella for TEM studies using focused ion beam technique. EDX elemental mapping and high angle annular dark field mode‐STEM were performed to monitor changes of the morphology and interdiffusion phenomena after heating up to 250 °C. A grain growth started during heating and the chemical layer structure was smeared out partly but remained in several grains and was found to be adjusted parallel to a major lattice plane in a crystallite. High resolution TEM shows polysynthetic twinning in a number of crystals.
Hybrid Nanoscale Architecture for Enhancement of Antimicrobial Activity: Immobilization of Silver Nanoparticles on Thiol‐Functionalized Polymer Crystallized on Carbon Nanotubes
Authors: Misra R. Devesh K. , Girase Bhupendra , Depan Dilip , Shah Jinesh S. 
Published: October 2011

AbstractWe describe here the synthesis and antimicrobial activity of an innovative nanohybrid system, characterized by attachment of silver nanoparticles (AgNPs) to the thiol‐functionalized polymer that was periodically crystallized on carbon nanotubes (CNTs). The synthesis of the nanohybrid architecture first involved direct crystallization of thiol‐functionalized copolymer along the long axis of CNTs, followed by attachment of AgNPs to the thiol‐group of functionalized copolymer. The antimicrobial activity was assessed in terms of interaction withEscherichia coli, where the constituents of the nanohybrid structure play a synergistic role. The antimicrobial activity was approximately four orders of magnitude greater than the ex situ precipitated bare AgNPs. Possible mechanisms underlying enhanced antimicrobial activity are discussed. The study underscores the potential of uniquely combining CNTs and biopolymers for biomedical applications, in the present case, antimicrobial activity.
Liquid‐Crystalline Perylene Diester Polymers with Tunable Charge‐Carrier Mobility

Published: October 2011

AbstractNew classes of liquid‐crystalline semiconductor polymers based on perylene diester benzimidazole and perylene diester imide mesogens are reported. Two highly soluble side‐chain polymers, poly(perylene diester benzimidazole acrylate) (PPDB) and poly(perylene diester imide acrylate) (PPDI) are synthesized by nitroxide‐mediated radical polymerization (NMRP). PPDB shows n‐type semiconductor performance with electron mobilities of 3.2 × 10−4 cm2 V−1 s−1 obtained in a diode configuration by fitting the space‐charge‐limited currents (SCLC) according to the Mott–Gurney equation. Interestingly, PPDI performs preferentially as a p‐type material with a hole mobility of 1.5 × 10−4 cm2 V−1 s−1, which is attributed to the less electron‐deficient perylene core of PPDI compared to PPDB. Optical properties are investigated by UV‐vis and fluorescence spectroscopy. The extended π‐conjugation system due to the benzimidazole unit of PPDB leads to a considerably broader absorption in the visible region compared to PPDI. HOMO and LUMO levels of the polymers are also determined by cyclic voltammetry; the resulting energy band‐gaps are 1.86 eV for PPDB and 2.16 eV for PPDI. Thermal behavior and liquid crystallinity are studied by differential scanning calorimetry, polarized optical microscopy, and X‐ray diffraction measurements. The results indicate liquid‐crystalline order of the polymers over a broad temperature range. These thermal, electrical, and optical properties make the perylene side‐chain polymers attractive materials for organic photovoltaics.
Development and Evaluation of Porous Materials for Carbon Dioxide Separation and Capture
Authors: Bae Youn‐Sang , Snurr Randall Q. 
Published: October 2011

AbstractThe development of new microporous materials for adsorption separation processes is a rapidly growing field because of potential applications such as carbon capture and sequestration (CCS) and purification of clean‐burning natural gas. In particular, new metal‐organic frameworks (MOFs) and other porous coordination polymers are being generated at a rapid and growing pace. Herein, we address the question of how this large number of materials can be quickly evaluated for their practical application in carbon dioxide separation processes. Five adsorbent evaluation criteria from the chemical engineering literature are described and used to assess over 40 MOFs for their potential in CO2 separation processes for natural gas purification, landfill gas separation, and capture of CO2 from power‐plant flue gas. Comparisons with other materials such as zeolites are made, and the relationships between MOF properties and CO2 separation potential are investigated from the large data set. In addition, strategies for tailoring and designing MOFs to enhance CO2 adsorption are briefly reviewed.
Synthesis of high performance polyamides utilizing copper‐catalyzed amidation of a dibromoarene with different diamides
Authors: Ghaemy Mousa , Nasr Farzaneh Hashemi 
Published: October 2011

AbstractA series of diphenylquinoxaline‐containing polyamides were prepared from the condensation polymerization of 2,3‐bis (4‐bromophenyl) quinoxaline (DBQ) with various primary and secondary diamides via copper‐catalyzed amidation reaction. The polyamides were characterized with FTIR, NMR, GPC, differential scanning calorimeter, and thermo gravimetric analysis, and their solubility and viscosity were measured. The polyamides synthesized here are amorphous and showed relatively good solubility in polar aprotic solvents and demonstrate the ability to form brownish hard films by solvent casting; their inherent viscosities ranged from 49 to 55 mL/g. The average molecular weights of polyamides were in the range of Mw = 11,950–5592 g/mol (MWD = 1.21–1.87). These polyamides had relatively high thermal stability with Tg values up to 276°C, 10% weight loss temperatures (T10%) in the range of 364–476°C, and char yields at 600°C in N2 up to 72%. They also exhibit emission in the solid state and in dilute (0.2 g/dL) DMAc solution at 425–484 nm with photoluminescence quantum (ϕf) yields in the range of 14–23%. © 2011 Wiley Periodicals, Inc.
