Purpose

Treatment of moderate to severe stable slipped capital femoral epiphysis (SCFE) remains a challenging problem. Open reduction by modified Dunn procedure carries a considerable risk of osteonecrosis (ON). Imhauser osteotomy is capable of realigning the deformity without the risk of ON, but the remaining metaphyseal bump is implicated with significant chondro-labral lesions and accelerated osteoarthritis. We conducted this study to evaluate the efficacy and safety of Imhauser osteotomy combined with osteochondroplasty (OCP) through the surgical hip dislocation (SHD) approach.

Methods

A prospective series of 23 patients with moderate-severe stable SCFE underwent Imhauser osteotomy and OCP through SHD. The mean age was 14.4 years (13 to 20) and the mean follow-up period was 45 months (24 to 66). The outcome measures included clinical and radiological parameters and Harris hip score (HHS) was used as a functional score.

Results

The mean HHS improved significantly from 65.39 to 93.3. The limb length discrepancy improved by a mean of 1.72 cm. The mean flexion and abduction arcs showed a significant improvement (mean increase of 37.5° and 18.5°, respectively). The mean internal rotation demonstrated the most significant improvement (mean increase of 38.5°). All the radiographic parameters improved significantly; including anterior and lateral slip angles (mean improvement 37.52° and 44.37°, respectively). The mean alpha angle decreased by 39.19°. The articulo-trochanteric distance significantly increased to a mean of 23.26 mm. No cases of ON or chondrolysis were identified.

Conclusion

Combined Imhauser osteotomy and OCP through the surgical dislocation approach provide a comprehensive and safe management of moderate to severe stable SCFE.

Redressing harms to migrant domestic workers: global and regional spaces
Authors: Mahon Rianne
Published: May 2020

This article analyses spaces for seeking redress for the harms experienced by migrant care workers and those left behind, working with the concept of depletion through social reproduction. While ‘global care chains’ also highlights the tolls exacted, depletion through social reproduction adds the important quasi-legal concept of ‘harm’, explicitly inviting reflection on spaces for redress and claims-making. Nation-states clearly constitute important spaces for seeking redress but migrants are left as ‘partial citizens’, protected by neither receiving nations nor their own governments. Accordingly, this article focuses on spaces for claiming rights at the global and regional (Asia-Pacific) scales, as well as the networks of international organisations, civil society organisations and trade unions that can use these spaces to claim redress.
Paleocene Larger Foraminifera from the Pyrenean Basin with a recalibration of the Paleocene Shallow Benthic Zones
Authors: Serra-Kiel J. , Vicedo V. , Baceta J.I. , Bernaola G. , Robador A.
Published: May 2020

A taxonomic study of the larger foraminifera found in Paleocene rocks from the Pyrenean basin has led to the description of sixty taxa including two new species: Alveolina korresensis and Valvulineria bacetai. In this work, we present a chronostratigraphic recalibration of the Paleocene Shallow Benthic Zones (SBZ 1 to SBZ 4) based on correlation with calcareous nannofossil and planktic foraminifera biozones, all integrated within the stratigraphic framework of Paleocene platform to basin depositional sequences established for the whole Pyrenean domain. The samples were collected in autochtonous and parautochtonous deposits from ten key shallow platform stratigraphic sections, representative from coastal to platform margin depositional settings. The results from two base of slope sections with numerous intercalations of calcareous turbidites with penecontemporaneous platform-derived biota have been integrated in the study. The regional chronostratigraphic framework is derived from magneto-biochronological studies carried out in the Zumaia section, global reference section for the Danian-Selandian and Selandian-Thanertian GSSPs. The new calibration of the Paleocene SBZs is summarized as follows. The SBZ 1 is constrained to the first 1.09 m.y. of the Paleocene; this first Paleogene biozone lacks distinct larger foraminifera biomarkers and thus is defined by an association of non-exclusive taxa composed of Valvulineria patalaensis, Stomatorbina? binkhorsti, P.? antiqua and Bangiana hanseni. The SBZ 2 now appears as the biozone encompassing most of the Danian stage (from ca. 64.91 m.y. to 61.6 m.y.), and is characterized by the association of Haymanella elongata, Haymanella paleocenica, Kayseriella decastroi, Rotospirella conica, Pyrenerotalia depressa, Elazigina dienii and Paralockhartia eos. The SBZ 2-SBZ 3 boundary coincides with the base of the Selandian stage (ca. 61.6 m.y.). The SBZ 3 biozone is defined by Glomalveolina primaeva, Periloculina slovenica, Vania anatolica, Coskinon rajkae, Fallotella alavensis, Cribrobulimina carniolica, Miscellanea yvettae, Miscellanea juliettae, Miscellanites primitivus, Miscellanites minutus, Ranikothalia soldadensis, Nummulites heberti and Discocyclina seunesi. The SBZ 3-SBZ 4 boundary is now ascribed to ca. 57.2 m.y. The SBZ 4 biozone appears characterized by Glomalveolina levis, Alveolina korresensis, Hottingerina lukasi, Daviesina garumnensis, Assilina yvettae, Assilina azilensis and Nummulites catari. The SBZ 4-SBZ 5 boundary is placed at the Paleocene-Eocene boundary event (ca. 56.0 m.y.).
Moiré effect in double-layered coaxial cylinders
Authors: Saveljev Vladimir , Han Woojun , Lee Hakcheol , Kim Jaewan , Kim Jaisoon
Published: May 2020

The moiré effect in multi-layered cylindrical objects was studied theoretically and experimentally. In theory, the central projection of double-layered convex and concave half-cylinders was considered. Based on the projected period expressed analytically in terms of the incidence angles, the period of the moiré patterns on the axis was obtained as the closed-form expression; the off-axis effect was analyzed qualitatively. The distance was discovered, where the period as the function of the angle is nearly constant. The experiments performed with two cylindrical devices confirm the theory. The results can be applied to nanoparticles and curved/flexible displays.

Single-layer metamaterial bolometer for sensitive detection of low-power terahertz waves at room temperature
Authors: Kim Yongjune , Kim Duckjong , Lee Sang-Hun , Seo Minah , Jung Hyun-June , Kang Boyoung , Lee Seung-Mo , Lee Hak-Joo
Published: May 2020

This study demonstrates a metamaterial bolometer that can detect terahertz (THz) waves by measuring variations in electrical resistance. A metamaterial pattern for enhanced THz waves absorption and a composite material with a high temperature coefficient of resistance (TCR) are incorporated into a single layer of the bolometer chip to realize a compact and highly sensitive device. To detect the temperature change caused by the absorption of the THz waves, a polydimethylsiloxane mixed with carbon black microparticles is used. The thermosensitive composite has TCR ranging from 1.88%/K to 3.11%/K at room temperature (22.2-23.8°C). In addition, a microscale metamaterial without a backside reflector is designed to enable the measurement of the resistance and to enhance the sensitivity of the bolometer. The proposed configuration effectively improves thermal response of the chip as well as the absorption of the THz waves. It was confirmed that the irradiated THz waves can be detected via the increment in the electrical resistance. The resistance change caused by the absorption of the THz waves is detectable in spite of the changes in resistance originating from the background thermal noise. The proposed metamaterial bolometer could be applied to detect chemical or biological molecules that have fingerprints in the THz band by measuring the variation of the resistance without using the complex and bulky THz time-domain spectroscopy system.
Experimental demonstration of the magnetic field concentration effect in circuit-based magnetic near-zero index media
Authors: Chen Youqi , Guo Zhiwei , Wang Yuqian , Chen Xu , Jiang Haitao , Chen Hong
Published: May 2020

The electromagnetic field concentration effect can greatly enhance light-matter interaction and is of practical interest in applications such as wireless power transfer and sensors. Zero-index media, unusual materials with near-zero relative permittivity (ɛ) and/or permeability (µ), play a key role in tailoring the properties of electromagnetic waves in unique ways. In this work, circuit-based isotropic µ-near-zero (MNZ) media were theoretically proposed and constructed based on two-dimensional transmission lines with lumped elements. Magnetic field concentration was experimentally demonstrated in this circuit-based system, which could be realized by using a small MNZ scatterer and the results agreed well with simulations. Moreover, the MNZ scatterer exhibited a robust enhancement of the magnetic field regardless of its position and number. By applying the magnetic field concentration effect of MNZ scatterers, we also study the flexible manipulation of the electromagnetic energy along different paths. These results not only provide a versatile platform to study abnormal scattering phenomena in metamaterials, but also offer a route to enhance the magnetic field in planar systems. Moreover, the manipulation of magnetic field under multiple MNZ scatterers may enable their use in new applications, such as in the robust energy transfer with properties of long-range and multiple receivers

We present a flexible all-polarization-maintaining (PM) mode-locked ytterbium (Yb):fiber laser based on a nonlinear amplifying loop mirror (NALM). In addition to providing detailed design considerations, we discuss the different operation regimes accessible by this versatile laser architecture and experimentally analyze five representative mode-locking states. These five states were obtained in a 78-MHz configuration at different intracavity group delay dispersion (GDD) values ranging from anomalous (-0.035 ps2) to normal (+0.015 ps2). We put a particular focus on the characterization of the intensity noise as well as the free-running linewidth of the carrier-envelope-offset (CEO) frequency as a function of the different operation regimes. We observe that operation points far from the spontaneous emission peak of Yb (∼1030 nm) and close to zero intracavity dispersion can be found, where the influence of pump noise is strongly suppressed. For such an operation point, we show that a CEO linewidth of less than 10-kHz at 1 s integration can be obtained without any active stabilization.

Authors: Ma Chaoxuan , Wang Xiaoxi , Mookherjea Shayan
Published: May 2020

Photon-pair generation at telecommunication wavelengths using high-quality silicon microring resonators is an active area of research. Here, we report on significant progress towards the ultimate goal of an integrated silicon microchip for bright generation of photon pairs with multiple stages of tunable optical filtering on the same chip. A high pair generation brightness of 6.5×1010 pairs/s/mW2/nm is achieved. The resonance of the high-Q silicon microring resonator can be monitored using a high dynamic range readout of a photocurrent in an all-silicon p-i-n diode fabricated across the waveguide cross-section, which is used to align the ring resonance to the passbands or stopbands of the filters.

Published: May 2020

We measure the dynamics of the thermo-optical nonlinearity of both a mode-gap nanocavity and a delocalized mode in a Ga0.51In0.49P photonic crystal membrane. We model these results in terms of heat transport and thermo-optical response in the material. By step-modulating the optical input power we push the nonlinear resonance to jump between stable branches of its response curve, causing bistable switching. An overshoot of the intensity followed by a relaxation tail is observed upon bistable switching. In this way, the thermal relaxation of both the localized resonance and the delocalized resonance is measured. Significant difference in decay time is observed and related to the optical mode profile of the resonance. We reproduce the observed transient behavior with our thermo-optical model, implementing a non-instantaneous nonlinearity, and taking into account the optical mode profile of the resonance, as experimentally measured.

Published: May 2020

We propose an indirect method for generating a complex hologram and phase-only hologram from an amplitude hologram using the Hilbert transform. The Hilbert transform generates an imaginary part of complex amplitude from only an amplitude hologram, resulting in the reduction of the total computational complexity of complex and phase-only holograms. More importantly, the proposed method can reduce the hardware resources of dedicated hologram processors.

Authors: Zafary Farzaneh
Published: May 2020

Whenever an organization decides to implement an ERP, it must assess its readiness to implement these complex systems. Therefore, the present study aims at considering the pre-implementation phase of ERP and the factors affecting the readiness of the organization for successful implementation of these systems. In this research, the SWOT matrix was used to classify the identified factors. Moreover, fuzzy-dimensional network analysis was used to evaluate decision options due to the weakness of SWOT technique. Since the factors involved in SWOT analysis are not only disjointed, but sometimes there are relationships among some of its factors. Therefore, internal and external factors of the organization are evaluated and prioritized in the research. In addition, finding the strategic position of the organization and identifying the appropriate strategies and prioritizing them to improve the organization's readiness for ERP implementation were other tasks in this research. After analyzing the data, 25 organizational factors are prioritized. The numerical results indicated that the organization is in the offensive position therefore, four strategies are designed and prioritized according to its position.

Transplanting Livers From “HCV-Positive” Donors To HCV-Negative Recipients: Increased Experience But Many Unanswered Questions
Authors: Polanco Nathalie Pena , Goldberg David
Published: May 2020

Over the past several years, single- and multi-center case series have reported on the successful use of livers from hepatitis C virus (HCV)-antibody positive and HCV-viremic donors to HCV-negative recipients. Several authors have studied not only the efficacy of this practice but also its cost-effectiveness of transplanting HCV-infected organs to HCV-negative donors. However, previous studies had limited follow-up and had not examined transplants beyond the beginning of 2018. Using national data from 2014–2018, Thuluvath et al. demonstrated that post-transplant outcomes of recipients from either HCV-antibody and/or HCV-viremic donors were not different than those using livers from HCV-negative donors.
CDC Company Towns in Cameroon: A Case of Shaping Built Space to Articulate Power and Social Control in Colonial and Postcolonial Perspectives
Authors: Njoh Ambe J. , Chie Esther P. , Bigon Liora
Published: May 2020

The article analyzes company towns with particular emphasis on the workers’ camps of the Cameroon Development Corporation (CDC) in Cameroon. The avowed purpose of the camps from their inception during the colonial era has always been to meet the housing needs of workers. However, the article contends that the camps were designed to accomplish two principal, albeit unstated, objectives, namely, 1) to articulate power and maintain social order in built space; and 2) to transmit Eurocentric ideals of work and general conduct to the workers. Company towns are not only of historical value, they are also of contemporary importance as they remain conspicuous features of built space in Cameroon in particular and Africa in general.

Mirarse en la víctima: reconfiguración de la culpabilidad moral
Authors: Etxeberria Mauleon Xabier
Published: May 2020

En este estudio se defiende que la culpabilidad, frente a sus numerosos críticos, es una categoría imprescindible para la ética que se hace cargo de la realidad del mal. Pero, a la vez, se postula que solo se expresa adecuadamente si es vivida por el culpable mirándose en la víctima. Es algo que tienden a ignorar tanto los que la critican como los que la defienden. Cuando, en cambio, se percibe la culpabilidad con esta focalización, todo queda reconfigurado: el centramiento en la subjetividad del que obró mal, el sentimiento de culpa, la relación entre las variables de la culpa, la responsabilidad, el arrepentimiento. Se muestra así que la culpabilidad vivida con autenticidad hace justicia a la víctima y, concomitantemente, es vía de sanación para el victimario.

Estratégias das Apaes federadas para impactar a educação e assistência dos excepcionais no Brasil: Uma análise histórica entre os anos de 1960 e 1970
Authors: Bezerra Giovani Ferreira
Published: May 2020

Este texto aborda estratégias mobilizadas pelos dirigentes apaeanos em sua atuação no campo da excepcionalidade, com vistas a obterem para si atenção pública, poder político e recursos financeiros do governo federal brasileiro antes da criação do Centro Nacional de Educação Especial (Cenesp), em 1973. Recorre-se à pesquisa histórica e documental, compilando-se os dados por meio de legislações e documentos emanados do poder público, de jornais de circulação geral, editados durante as décadas de 1960-1970, bem como, precipuamente, de exemplares do impresso periódico Mensagem da Apaeno período de 1963 a 1973. Pôde-se evidenciar que os líderes apaeanos atuaram junto ao poder instituído durante os governos militares instalados pós 1964, ampliando sua rede de influências e contando com algum apoio governamental. A partir de contingências nacionais e internacionais desenhadas no início dos anos de 1970, a criação do Cenesp estabeleceu uma nova dinâmica no campo da Educação Especial, que assim passou a ser oficialmente designada e institucionalizada, direcionada e regulada pelo governo federal, muito embora não se tenha cessado a ingerência privado-filantrópica nos rumos dessa modalidade educacional.
Ludzka tożsamość wobec ekokolonializmu
Authors: Mamzer Hanna
Published: May 2020

Contemporary reality of everyday functioning of postmodern humans, provokes deep changes in thinking of human identities and human relations it natural and cultural surroundings. Human sciences have to confront the fact, that it is no longer possible to divide human identities from those of non-humans. The connections between human and non-humans are clear and significant, and they are reflected on by the most prominent thinkers in the fields of social sciences (W. Kymlicka) and ecology (E.O. Wilson), at the same time. Understanding human identity requires connecting it with is natural surrounding, again. And this surrounding shall not be divided into “natural” and “cultural” ones anymore. Clarity of such divisions is seriously questioned by impossibility of drawing clear border lines between them. Such thinking creates new context for understanding humans. And this requires new tools as well: therefore it becomes very clear that humanities/social sciences and real science need to speak one voice.
Identyfikacja regionalna mieszkańców pogranicza polsko-niemieckiego
Authors: Gołdyka Leszek
Published: May 2020

According to the author about a half of the Polish-German borderland inhabitants are “the winners” of the systemic transformation, they are pragmatic individualists and materialists. In their case identification with any other person than themselves and members of the closest family is rare. The otherhalf are members of enclaves and “tribes”. Solidarity, which may be found in their system of values, is however limited to their “fellows of the same mind”, thus it has a particular character. These are the “losers” of the transformation. The feeling of material deprivation, their identification particularism generates and enhances a reluctant attitude to the reconstruction of the German cultural heritage in the Polish western borderland. According to the author, the reconstruction of this heritage creates the feeling of non-obviousness as to the possession of the western borderland, thus evoking a negative attitude to everything that is German or, generally, ethnically “strange”. The first ones treat land in a materialist, instrumental manner (as “plots of land” for development), they may recognize it as a subject of a profitable transaction, not making it the subject of a moral dilemma whether the achievement of their interest reduces the economic strength of the Polish state. For the other ones, land has got a symbolic value. In the Author’s opinion, the inhabitants of the western borderland, though in many objective aspects similar, are not subjectively close to one another. Dichotomously divided, they create a territorial group, not a community. On account of the individualistic, pragmatic and materialistic orientation of one half of the inhabitants, in this paper the Polish – German borderland is called a space of identification vacuum, whereas on account of the enclave-like and tribal orientation of the other half of its inhabitants it is called a space of identification failure.

A flexible platform for controlled optical and electrical effects in tailored plasmonic break junctions
Authors: Laible Florian , Braun Kai , Hauler Otto , Eberle Martin , Kern Dieter P. , Meixner Alfred J. , Fleischer Monika
Published: May 2020

Mechanically controllable break junctions are one suitable approach to generate atomic point contacts and ultrasmall and controllable gaps between two metal contacts. For constant bias voltages, the tunneling current can be used as a ruler to evaluate the distance between the contacts in the sub-1-nm regime and with sub-Å precision. This ruler can be used to measure the distance between two plasmonic nanostructures located at the designated breaking point of the break junction. In this work, an experimental setup together with suitable nanofabricated break junctions is developed that enables us to perform simultaneous gap-dependent optical and electrical characterization of coupled plasmonic particles, more specifically bowtie antennas in the highly interesting gap range from few nanometers down to zero gap width. The plasmonic break junction experiment is performed in the focus of a confocal microscope. Confocal scanning images and current measurements are simultaneously recorded and exhibit an increased current when the laser is focused in the proximity of the junction. This setup offers a flexible platform for further correlated optoelectronic investigations of coupled antennas or junctions bridged by nanomaterials.
“Au Fond d’un Placard”
Authors: Shiflett Campbell
Published: May 2020

An analysis of self-allusion in Francis Poulenc’s Ier Nocturne for piano (1929/30) not only reveals a complex network of interrelated programmatic and personal associations but also suggests how attention to allusion offers a means of experiencing the piece queerly. The nocturne’s allusions to earlier works by Poulenc point toward a set of shared topics, including childhood, the pastoral, the erotic, and the composer’s romantic relationship with painter Richard Chanlaire, while a chromatic sequence in the nocturne’s coda anticipates the associations of this progression with grace, anxiety, and the divided self in two later works. Alongside these allusive referents, the nocturne’s shifting levels of discourse, dramatic form, and ironic modality inspire a hearing of the piece as a coming-out narrative, whose constant deferral of meaning renders the nocturne different from itself. This interpretation aligns Poulenc’s nocturne with contemporary works by authors Jean Cocteau and Marcel Proust, whose writings similarly treat these (self-)referential deferrals as indicative of queer life and trope this difference to instantiate a queer hermeneutics. As a performance of difference and reference, Poulenc’s nocturne benefits from a mode of listening that reflects these deferrals, acknowledging allusion’s effects on listeners and queerly redefining the musical work in the process.

The existence of cytoplasmic passages between germ cells and their potential function in the control of the spermatogenic process has long been an intriguing question. Evidence of the important role of such structures, known as intercellular bridges (ICB), in spermatogenesis has been implicated by the failure of spermatogenesis in testis-expressed gene 14 (Tex14) mutant mice, which lack the ICBs, to progress past the pachytene spermatocyte stage. Using these Tex14 mutants, the present study evaluated, for the first time, the behavior and synchrony of the spermatogonial lineage in the absence of ICBs. Our data suggest that the absence of these cytoplasmic connections between cells affects the expansion of the undifferentiated type A (Aundiff) spermatogonia compartment and their transition to A1, resulting in a significant numerical reduction of differentiating A1 spermatogonia, but did not interfere with cell amplification during subsequent mitotic steps of differentiating spermatogonia from A1 through intermediate (In). However, beginning at the type B spermatogonia, the synchrony of differentiation was impaired as some cells showed delayed differentiation compared to their behavior in a normal seminiferous epithelium cycle. Thus although spermatogonial development is able to proceed, in the absence of ICBs in Tex14−/− mutants, the yield of cells, specific steps of differentiation, the synchrony of the cell kinetics, and the subsequent progression in meiosis are quantitatively lower than normal.

HAN, Byung-Chul: El aroma del tiempo. Un ensayo filosófico sobre el arte de demorarse, trad. cast. Paula Kuffer, Herder, Barcelona, 2015, 168p.
Authors: Sánchez Gómez Pablo Bernardo
Published: May 2020

Recensión de la obra de Byung-Chul Han "El aroma del tiempo", donde analiza la visión aceptada de una aceleración del tiempo moderno, a través de autores como Lyotard, Baudrillard o Arendt, señalando que, más que ésta, debe considerarse la pérdida de un fundamento, de un elemento ordenador del tiempo. De este modo, no se padece tanto una aceleración de los tiempos como una ausencia de sentido, de dirección, que posibilite así la experiencia de una duración.

Research with, in, and for First Nations communities is often carried out in a complex environment. Now in its fourth year, the Poverty Action Research Project (PARP) has learned first-hand the nature of some of these complexities and how to approach and work through various situations honouring the Indigenous research principles of respect, responsibility, reciprocity, and relevance (Kirkness & Barnhardt, 2001). By sharing stories from the field, this article explores the overarching theme of how the worlds of academe and First Nations communities differ, affecting the research project in terms of pace, pressures, capacity, and information technology. How PARP research teams have worked with these challenges, acknowledging the resilience and dedication of the First Nations that are a part of the project, provides insights for future researchers seeking to engage in work with Indigenous communities.
Working Together with South Saami Birth Stories – A Collaboration Between a Saami Midwife and a Saami Researcher
Authors: Kroik Åsa Virdi , Joma Jonhild
Published: May 2020

This paper presents some results from a community-based project among local South Saami in the Norwegian and Swedish part of Saepmie. I was co-coordinating a two-year community-sponsored project in the community (Røyrvik) in which a local South Saami midwife documented stories from elder Saami about childbirth in earlier times, both from their own memories and from stories they knew. Her work became an article in a book, and the project helped us to understand much more about childbirth and general living conditions for Saami one to three generations ago in this area. As a PhD candidate, I have complemented her work with a theoretical framework (Indigenous Research Methods, colonial perspective), a historical analysis, and a contemporary context. Apart from presenting an example of stories she was given and how they can give us new knowledge. But I will focus on the meanings, processes, theories and practices of engaged Indigenous community research. I will describe our different methods and the benefit of working together and will point out how it will further research.
Crafting Culturally Safe Learning Spaces: A Story of Collaboration Between an Educational Institution and Two First Nation Communities
Authors: Fraser Joanna , Voyageur Evelyn
Published: May 2020

This is a story of crafting a culturally safe learning space in the context of First Nations communities. It is told by two nurse educators working together, one who is Indigenous and one who is not. The word “crafting” is used to describe the collaborative and aesthetic process of co-constructing learning with students, community members and the environment. The relationship between the educational institution and the First Nations communities was guided by the concept of cultural safety. Cultural safety politicizes the notion of culture and disrupts the power imbalance between nurses and the people they work with. A process of collaborative conscientization was used to decolonize our institution and ourselves. This led to new possibilities of crafting an ethical learning space where Eurocentric ideologies could be dislodged from the center in order for Indigenous ways of knowing and learning to emerge. Students experienced a form of relational accountability for their learning through participation in community ceremonies and protocols. What resulted was a unique and transformative learning experience for fourth year Bachelor of Science in Nursing students offered in collaboration between an educational institution and two remote First Nations communities.
The Community Readiness Initiative in Kugluktuk, Nunavut: The Challenge of Adapting an Indigenous Community-Based Participatory Framework to a Multi-Stakeholder, Government- Designed Project Environment
Authors: Gabel Chelsea , Cameron Emilie
Published: May 2020

In April 2014, McMaster University and Carleton University collaborated with Kugluktuk, an Inuit community in Nunavut to survey community views on resource development and produce a larger community report. This was part of a Community Readiness Initiative (CRI) piloted by the Canadian Northern Development Agency (CanNor) to assess the socio-economic needs of communities across the North prior to mine development. Kugluktuk is the first of seven communities across Nunavut, the Northwest Territories, and the Yukon to produce their final report. Universities have started to play an important role in developing a ‘third mission’ whereby researchers are encouraged to collaborate with non-academic organizations. This collaborative approach can include contract research and consulting, as well as informal activities like providing ad hoc advice and networking with practitioners. Working as an academic in this environment can create tensions, but it can also create opportunities to foster and ensure meaningful input and consultation from a variety of stakeholders. This paper focuses in depth on the collaborative nature of the CRI process that began in April 2014 and ended in August 2015 with an emphasis on the community-based participatory research approach that we took. With insights that apply equally well outside of the Kugluktuk context, the approach that we took also provides a useful model for engaging with issues on mining and resource development opportunities.
Community-Based Intersectionality: The Changing Public Services Project
Authors: Findlay Tammy , Cohen Michelle , Johnston Mary-Dan
Published: May 2020

The paper reflects on a changing public service project regarding women and intersectional analysis in Halifax, Canada. The project sought to facilitate collective mobilizations to challenge austerity and to imagine public services that meet the needs of the citizens who use them, and the workers that provide them. We provide an overview of the project, and then explore our attempt at adapting “multistrand” intersectional policy analysis (Hankivsky & Cormier, 2011) to a community-based context. In considering the challenges and opportunities associated with this work, the paper concludes that the changing public service project created space for an innovative approach to community-based research that can guide both participatory policy analysis and collective action.
Malinche, Pocahontas, and Sacagawea: Indian Women as Cultural Intermediaries and National Symbols
Authors: Khelifa Amani
Published: May 2020

In her book, Rebecca K. Jager compares and contrasts the lives and legends of three Indigenous North American women: Malinche, Pocahontas, and Sacagawea. Jager’s research answers an earlier call by Native-American historian and feminist scholar Clara Sue Kidwell in her 1992 Ethnohistory article, “Indian Women as Cultural Intermediaries,” to revisit these stories from a non-Eurocentric perspective.
School Performance, Leadership and Core Behavioral Competencies of School Heads: Does Higher Degree Matter?
Authors: Caingcoy Manuel E. , Lepardo Romeo Jr L.
Published: May 2020

This paper finds out whether a higher degree matters in school performance, and in demonstrating leadership and core behavioral competencies among school heads. This was conducted to support the existing and future policies of the Department of Education and interested funders for the scholarship and advanced studies of school heads. Using a cross-sectional method, it involved 192 randomly selected participants. Data on school performance was obtained at the office of Surigao del Sur Division, while data on competencies were gathered through the self-administered assessment tools developed by the Department of Education. These data were analyzed using descriptive statistics and analysis of variance. Results revealed that there was no significant difference in the school performance of school heads. This implies that the highest degree obtained is not a guarantee for better school performance. As found, those with doctorate degrees had a very high and consistent demonstration in all dimensions of leadership and core behavioral competencies. As unveiled, there were significant differences in the demonstrated competencies based on the highest educational qualifications. These imply that obtaining the highest degrees can allow school heads to acquire, develop, and demonstrate the competencies consistently better than their counterparts. Results have implications for DepEd officials, funders, and policy-makers.
