Behind the Scenes: Gender Equality in Local Union Leadership
Authors: Bernard Pelletier Marie-Pier , Le Capitaine Catherine 
Published: June 2024

This article examines the experiences of local union presidents with respect to gender equality. Based on a qualitative case study of members of union committees dedicated to the status of women and local union presidents working in the Québec education sector, our research points to an unprecedented breakthrough of women serving as local presidents. Nevertheless, the existence of a “triple burden,” the persistence of gender stereotypes and a male union culture, the lack of training and mentoring, and the reliance on solicitation are all hindering the achievement of gender equality. Our research findings also highlight a weak representation of the diversity of social identities within the union organization studied.SummaryThis article examines the experiences of local union presidents with respect to gender equality. In a context where equity, diversity and inclusion in the workforce are more relevant than ever, this paper aims to contribute to reflections on the democratic deficit of female representation in union organizations. The findings are based on a qualitative case study of members of two union committees dedicated to the status of women and sixteen local union presidents working in the Québec education sector. By gathering the views of these women and men, our research makes a case for the long-neglected place of women serving as local presidents within the union organization studied. It is the efforts made by the unions themselves that have gradually allowed women to enter the traditionally male-dominated union world. Behind this unprecedented breakthrough, however, are gaps that remain in achieving gender equality. Beyond a continuing numerical deficit of women, the difficulty of managing a “triple burden,” the persistence of gender stereotypes, the prevalence of a male union culture, the lack of training and mentoring, and the use of solicitation are major obstacles that prevent women from accessing local union leadership positions. In addition, the representation of diverse social identities (age, family status, race, etc.) is still not well represented at the local decision-making level of the union organization studied, even among elected women. Diversity and gender equality representation remain challenges to be prioritized to ensure a more sustainable and democratic union organization.

Published: June 2024

Effective school leadership plays a crucial role in addressing challenges, inspiring teachers, and creating an environment conducive to teachers. This study delved into the motivational techniques employed by public school heads in Panabo City. Teacher motivation is pivotal in improving educational outcomes and fostering a positive learning environment. This research employed a qualitative approach focusing on a single case to explore the various motivational techniques and strategies implemented by Public Secondary Senior High School Heads regarding their effectiveness and the challenges encountered in the context of Panabo City. Seven (7) key informants were chosen using a purposive sampling technique and underwent an in-depth interview. The gathered data were analyzed using a thematic analysis. The major themes identified pivots around rewards and recognition, professional development, collaboration, and open communication. The technique's effectiveness is measured through performance metrics, feedback mechanisms, and retention rates. The significant challenges experienced by the school heads include sustainability of motivation, tailoring techniques to different individuals, and requiring sufficient support and resources. On the other hand, the emergent themes in motivational strategies include resource allocation and institutional support, school community building, and an inclusive approach. Implementing motivational strategies successfully entails addressing the limited resources, resistance to change, and ensuring sustainability through continuous monitoring and institutional support. The themes were thoroughly discussed, defined, and reinforced with existing studies and literature. Moreover, the insights emphasized the importance of empathy, consistency, and a long-term vision. Recommendations include strengthening the techniques and strategies utilized, being updated on new trends in motivational strategy and improvement, and addressing challenges. By implementing the implications into practice and ensuring sustained effectiveness, school leaders must seek continuous feedback, establish performance metrics, remain adaptable to changes, and address challenges with flexible, tailored strategies that emphasize consistency, empathy, and understanding. This study has the potential to provide valuable perspectives for policymakers in education, as well as school administrators and teachers seeking to enhance teacher motivation and ultimately improve the quality of education.

Published: June 2024

Background: The idea of accelerated orthodontics is to modify the bone temporarily to enable teeth move faster in the jaws so as to shorten the orthodontic treatment time. With the increasing global interests in patients’ concerns about the duration of conventional orthodontic treatment and accelerated orthodontics, there is need to investigate further into the factors that could impact the patients’ satisfaction, perception and attitude towards accelerated orthodontics.
Aim: To investigate the impact of age and marital status of orthodontic patients on their satisfaction with conventional orthodontic treatment, as well as their perception and attitude towards accelerated orthodontics.
Materials and Methods: Using a questionnaire, a clinic-based cross-sectional and prospective study of orthodontic patients in a Nigerian teaching hospital was carried out between March, 2023 and May, 2024.The questionnaire contents involving their satisfaction with duration of orthodontic treatment and their perception and attitude towards accelerated orthodontics were analysed for associations with the patients’ age and marital status. The IBM SPSS version 25 was used to analyze the data involving descriptive statistics, the ANOVA and independent t-test. The significance level set at P< .05.
Results: Significant associations were found between patients’ age and their satisfaction with orthodontic treatment duration (P < .05) and one procedure of accelerated orthodontics (P<.05). No significant associations were found between their marital status and satisfaction with duration of orthodontic treatment, as well as with their perception and attitude towards accelerated orthodontics (P>.05).
Conclusion and Recommendation: Patients’ age had significant impact on satisfaction with orthodontic treatment duration, and slightly on perception and attitude towards accelerated orthodontics but marital status did not. More of such studies are required in other orthodontic communities for evidence-based clinical orthodontic practice.

Gum and resin from non-wood forest products (NWFP) play a crucial role in the income and livelihoods of small-scale farmers. Recently, there has been a significant increase in industrial demand for these products. Therefore, a study of “Tapping Technique” was conducted in 2022–23 to assess various traditional, mechanical, and gum enhancer applications for enhancing gum and resin production during both the winter and summer seasons. This study revealed that the Jhingam tree demonstrated excellent potential for gum production throughout the year. Specifically, the application of a 2% ethylene-based gum enhancer injected via the drill method at 1-meter height from the ground in trees with over 90 cm diameter significantly increased gum production quantity, rate, and quality. Analysis of physiochemical properties showed that this treatment resulted in higher moisture content, pH, and bulk density (0.76-0.78) while reducing tapped density. The Fat and protein content were also higher compared to other methods. The angle of repose indicated good capsule-filling properties at 31.87%.
On the other hand, the Arjun tree exhibited lower gum production potential compared to Jhingam, with most production occurring during the summer. Similar to Jhingam, the application of a 2% ethylene-based gum enhancer reduced the moisture content, pH, and bulk density while increasing the fat and protein content. Both gums showed high solubility in hot water, with a viscosity at 6.1 cP (high) at 100 rpm and 1 cP (low) at 10 rpm in a 1% solution. The angle of repose for Arjun gum was 25.33%.

AbstractMethods that allow soft matter to be fabricated with controlled structure and function would be beneficial for applications ranging from flexible electronics to regenerative medicine. Here, the assembly of a multifunctional gelatin matrix is demonstrated by triggering its self‐assembly and then enzymatically assembling biological functionality. Triggered self‐assembly relies on electrodeposition of the pH‐responsive hydrogelator, 9‐fluorenylmethoxycarbonyl‐phenylalanine (Fmoc‐Phe), in response to electrical inputs that generate a localized pH‐gradient. Warm solutions of Fmoc‐Phe and gelatin are co‐deposited and, after cooling to room temperature, a physical gelatin network forms. Enzymatic assembly employs the cofactor‐independent enzyme microbial transglutaminase (mTG) to perform two functions: crosslink the gelatin matrix to generate a thermally stable chemical gel and conjugate proteins to the matrix. To conjugate globular proteins to gelatin these proteins are engineered to have short lysine‐rich or glutamine‐rich fusion tags to provide accessible residues for mTG‐catalysis. Viable bacteria can be co‐deposited and entrapped within the crosslinked gelatin matrix and can proliferate upon subsequent incubation. These results demonstrate the potential for enlisting biological materials and mechanisms to biofabricate multifunctional soft matter.

The dynamics of primary source and electronic resource: The digital renaissance and the post‐reformation digital library
Authors: Ballor Jordan J. 
Published: April 2012

AbstractEditor's SummaryThe transition from mechanical printing to electronic information dissemination amounts to a digital renaissance, enabling primary source documents to be reborn as electronic resources. For history scholars, this presents opportunities and challenges for preserving centuries‐old original texts in a digital environment, supporting downloading and digital access and presenting original research. The Post‐Reformation Digital Library (PRDL) serves as a case study, capturing a select set of resources on theology and philosophy of the 15th to 18th centuries from a variety of physical locations and digital libraries. Through digitization, digital access and systematic cataloging, the PRDL – along with the database, social networking and dedicated website it has prompted – are helping to overcome barriers to access. Though a modest initiative, the progress of the PRDL demonstrates possibilities for rediscovering historical materials and making them available for modern scholarly studies.
The ISO 25964 data model for the structure of an information retrieval thesaurus
Authors: Will Leonard 
Published: April 2012

AbstractEditor's SummaryThe international standard for thesaurus structure, ISO 259641:2011 – Thesauri for Information Retrieval, published August 2011, presents an extensive data model more advanced than previous versions. The standard facilitates presenting a knowledge organization system in machine compatible SKOS (simple knowledge organization system) format. The model lays out the concepts and terminology applicable to single thesauri, establishing the important difference between concepts and terms. It provides strategies to go beyond simple hierarchical relationships and related concepts, clarifying the nature of relationships between concepts. The new standard addresses several details in thesaurus construction and use for information retrieval, including compound equivalence and node labels. The updated standard supports concept groups or microthesauri and provides for term notes and file versions. Mapping concepts between thesauri will be covered in Part 2 of the standard.

ObjectiveWe reviewed the technical changes and results achieved with the retrograde approach since we introduced it 7 years ago.Subjects and MethodsThe subjects were 1,268 patients who were treated for CTO between January 2004 and December 2010. They were investigated with respect to the success rate, the frequency of employing the retrograde approach and its outcome, and other factors.ResultsThe retrograde approach was employed in ∼30% of chronic total occlusion (CTO) patients (n = 281) and the retrograde guidewire success rate was 81.1%. The kissing wire technique was substituted for the retrograde approach in 126 of the 281 patients, with antegrade crossing of a guidewire being successful in 88 of them (70%). The retrograde approach was combined with the CART and reverse controlled antegrade retrograde tracking (CART) techniques in 22 and 21 patients, respectively. Among 83 patients treated with Corsair catheters, crossing of the CTO was achieved in 63. The overall procedural success rate was 79.7% (224 patients). Complications of the retrograde approach included collateral channel dissection (2.1%), channel perforation (1.7%), CTO perforation (1.7%), and donor artery occlusion (1.1%).ConclusionThe success rate and safety of the retrograde approach are both satisfactory if the appropriate devices and techniques are selected. © 2012 Wiley Periodicals, Inc.

AbstractBACKGROUND:Early marrow blast clearance 14 days after induction chemotherapy is an independent prognostic indicator of outcomes in acute myeloid leukemia (AML).METHODS:We evaluated the relationship between time to peripheral blood blast clearance after induction and disease status as assessed by day 14 and day 30 marrow biopsies in 162 patients with AML. Day 6 after induction was the optimal cutoff point determined by a receiver operating characteristic analysis and was selected to divide patients into early blast clearance (EBC; ≤6 days; n = 119) and delayed blast clearance (DBC; >6 days; n = 43) groups.RESULTS:DBC patients were older, but otherwise the 2 groups were comparable. Marrow blast clearance on day 14 after induction chemotherapy was observed in 84% of patients in the EBC group and 60% in the DBC group. With a median follow‐up of 1538 days, both relapse‐free survival (RFS) (442 vs 202 days, P = .0017) and overall survival (OS) (930 vs 429 days, P < .0001) were longer in the EBC group, and a multivariable analysis showed that EBC independently predicted clearance of marrow blasts at day 14 (P = .0018), remission (P = .0179), RFS (P = .0171), and OS (P = .0122).CONCLUSIONS:Early clearance of peripheral blood blasts after induction chemotherapy predicts for early marrow blast clearance, complete remission, RFS, and OS.

AbstractBACKGROUND:Cilengitide is a selective integrin inhibitor that is well tolerated and has demonstrated biologic activity in patients with recurrent malignant glioma. The primary objectives of this randomized phase 2 trial were to determine the safety and efficacy of cilengitide when combined with radiation and temozolomide for patients with newly diagnosed glioblastoma multiforme and to select a dose for comparative clinical testing.METHODS:In total, 112 patients were accrued. Eighteen patients received standard radiation and temozolomide with cilengitide in a safety run‐in phase followed by a randomized phase 2 trial with 94 patients assigned to either a 500 mg dose group or 2000 mg dose group. The trial was designed to estimate overall survival benefit compared with a New Approaches to Brain Tumor Therapy (NABTT) Consortium internal historic control and data from the published European Organization for Research and Treatment of Cancer (EORTC) trial EORTC 26981.RESULTS:Cilengitide at all doses studied was well tolerated with radiation and temozolomide. The median survival was 19.7 months for all patients, 17.4 months for the patients in the 500 mg dose group, 20.8 months for patients in the 2000 mg dose group, 30 months for patients who had methylated O6‐methylguanine‐DNA methyltransferase (MGMT) status, and 17.4 months for patients who had unmethylated MGMT status. For patients aged ≤70 years, the median survival and survival at 24 months was superior to what was observed in the EORTC trial (20.7 months vs 14.6 months and 41% vs 27%, respectively; P = .008).CONCLUSIONS:Cilengitide was well tolerated when combined with standard chemoradiation and may improve survival for patients newly diagnosed with glioblastoma multiforme regardless of MGMT methylation status. The authors concluded that, from an efficacy and safety standpoint, future trials of this agent in this population should use the 2000 mg dose. Cancer 2012. © 2012 American Cancer Society.

Published: April 2012

ABSTRACTCertain problems in the existing treatment of the stability of charge‐pump phase‐locked loops are identified and addressed in this work. New results concerning the instability, stability, and asymptotic stability of charge‐pump phase‐locked loops are obtained by means of Lyapunov's direct and indirect methods. Closer consideration of the local dynamics provides further insight into the system's patterns of behavior. In particular, the influence of circuit parameters on the nature of the steady‐state orbits is investigated. Copyright © 2012 John Wiley & Sons, Ltd.
