Authors: Hostinská Lucie , Kuneš Petr , Hadrava Jiří , Bosch Jordi , Scaramozzino Pier Luigi , Bogusch Petr
Published: August 2021

Some species of two tribes (Anthidiini and Osmiini) of the bee family Megachilidae utilize empty gastropod shells as nesting cavities. While snail-nesting Osmiini have been more frequently studied and the nesting biology of several species is well-known, much less is known about the habits of snail-nesting Anthidiini. We collected nests of four species of the genusRhodanthidium(R. septemdentatum,R. sticticum,R. siculumandR. infuscatum) in the Czech Republic, Slovakia, Catalonia (Spain) and Sicily (Italy). We dissected these nests in the laboratory and documented their structure, pollen sources and nest associates. The four species usually choose large snail shells. All four species close their nests with a plug made of resin, sand and fragments of snail shells. However, nests of the four species can be distinguished based on the presence (R. septemdentatum,R. sticticum) or absence (R. siculum,R. infuscatum) of mineral and plant debris in the vestibular space, and the presence (R. septemdentatum,R. infuscatum) or absence (R. sticticum,R. siculum) of a resin partition between the vestibular space and the brood cell.Rhodanthidium septemdentatum,R. sticticumandR. siculumusually build a single brood cell per nest, but allR. infuscatumnests studied contained two or more cells. For three of the species (R. siculum,R. septemdentatumandR. sticticum) we confirmed overwintering in the adult stage. Contrary toR. siculum,R. septemdentatumandR. sticticumdo not hide their nest shells and usually use shells under the stones or hidden in crevices within stone walls. Nest associates were very infrequent. We only found twoR. sticticumnests parasitized by the chrysidid waspChrysura refulgensand seven nests infested with pollen mites Chaetodactylus cf. anthidii. Our pollen analyses confirm thatRhodanthidiumare polylectic but show a preference for Fabaceae byR. sticticum.

Authors: Nazimek Katarzyna ,   Department of Immunology, Jagiellonian University Medical College, 18 Czysta St., 31-121 Krakow, Poland
Published: August 2021

At present, special efforts are being made to develop the strategies allowing for activation of long-lasting antigen-specific immune tolerance in therapy of allergic and autoimmune diseases. Some of these therapeutic approaches are aimed at modulating cell functions at genetic level by using miRNA-based and miRNA-targeting treatments. Simultaneously, the crucial role of extracellular vesicles as natural miRNA conveyors is highlighted for induction of antigen-specific immune tolerance, especially that they appear to be easily manipulatable for therapeutic applications. Among other immune-related miRNAs, miR-150 is getting special attention as it is differently expressed by immune cells at various stages of their maturation and differentiation. In addition, miR-150 is involved in different signaling cascades orchestrating humoral and cell-mediated mechanisms of both innate and adaptive immune responses. Therefore, miR-150 is considered a master regulator of immunity in mammals. Currently, physiological miR-150-dependent regulatory circuits and causes of their malfunctioning that underlie the pathogenesis of allergic and autoimmune disorders are being unraveled. Thus, present review summarizes the current knowledge of the role of miR-150 in the pathogenesis and complications of these diseases. Furthermore, the involvement of miR-150 in regulation of immune responses to allergens and self-antigens and in induction of antigen-specific immune tolerance is discussed with the special emphasis on the therapeutic potential of this miRNA.

Authors: Son Nguyen Hai
Published: August 2021

This paper deals with stability of solution map to a parametric control problem governed by semilinear elliptic equations with finite unilateral constraints, where the objective functional is not convex. By using the first-order necessary optimality conditions, we derive some sufficient conditions under which the solution map is upper semicontinuous with respect to parameters.

Authors: Gallardo Vazquez Dolores , Maqbool Shafat , Sánchez-Domínguez Juan de la Cruz
Published: August 2021

The 2030 Agenda implies an important commitment that should be achieved by companies, countries, and governments, and the goals set should be worked on with the aim to boost the areas they address. Corporate social responsibility is a tool for organizations to act on behalf not only of the public but also of all stakeholders, as affirmed by the stakeholders' theory. Given the interest the stakeholders have in achieving the Sustainable Development Goals, it is important to observe the attitudes and behaviors that the organizations develop to achieve their intended contribution. This chapter analyzes the companies´ attitudes and behaviors developed to fulfill five SDGs (from 1 to 5). The study is focused on the content analysis of the corporate social responsibility reports of 16 car manufacturing companies. At the end, the authors propose some future lines of research.
CSR and SDGs in Early-Stage Entrepreneurship
Authors: Martínez-Martínez Sofía Louise , Ventura Fernández Rafael , Plata Ríos Clara
Published: August 2021

Entrepreneurship conditions the sustainable development of a society by the economic, social, and environmental impact of new ventures. Specifically, startups, due to their high level of innovation and scalability, have an important role in fostering and accelerating the implementation of sustainable practices. An empirical analysis is carried out through data collected in the framework of the GEM project to define the extent in which startups innovation impact SDGs. The results highlight that the most frequently addressed goals belong to the economic sphere (e.g., SDG 8 and SDG 9), while environmental and social aspects are scarcely considered. More than half of the SDGs are addressed by less than 10% of the startups. A change in policies to promote SDGs is needed to foster the implementation of CSR strategies from early entrepreneurial stages, increase startups awareness, and face the lack of attention that some SDGs are receiving from the currently emerging innovation.

Published: August 2021

In the last years, the interest in eco-sustainable composites has consistently increased. Such innovative materials are actually a promising sustainable solution for structural strengthening since they can be an alternative to petroleum‐based materials, which are frequently used for masonry retrofitting. This work describes an experimental campaign dedicated to investigating the behavior of Fabric-Reinforced Cementitious Matrix (FRCM) with natural fibers (NFRCM) made with eco-sustainable materials. Experimental tests are performed on unreinforced masonry panels (URM) and reinforced ones (RM), for characterizing their mechanical behavior. URM samples are compared with RM ones accounting for their response under shear actions.
Use of Specially Treated Hazardous Waste as Filler in Polymer Coatings
Authors: Žlebek Tomáš , Hodul Jakub , Drochytka Rostislav
Published: August 2021

The objective of presented research was to verify and evaluate whether the treated hazardous waste (HW) can be used as filler in polymer coatings based on epoxy (EP) and polyurethane resin (PUR). The end product created by the incineration of municipal waste and cement dusts from cement kiln bypasses were chosen for solidification. The hazardous waste used was solidified by a homogenisation method using filter fly ash from fluidized bed combustion of lignite and silica flour as the solidifying agents. The aim was to use as much hazardous waste as possible and incorporate it into the polymer matrix of the coatings. The usability of the filler prepared in this way was verified by testing the tensile properties of polymer coatings, the surface hardness and the adhesion to the concrete. The cohesion of the coatings with concrete was observed using a digital optical microscope. It has been found that the PUR-based coatings with HW content show better properties than the coatings containing only the silica flour as a filler.

Authors: Jäntsch Sandra , Diederichs Ulrich
Published: August 2021

With the increase of graffiti since the beginning of the 1970s, the interest in proper removal and high-quality protection systems also have grown. To protect affected objects and buildings from damage caused by graffiti, anti-graffiti systems (AGS) can be used. In practice, it has already been shown that no AGS is suitable for all kind of surfaces. In this study, the effects of permanent anti-graffiti systems on various concrete surfaces are specifically investigated and evaluated with test series under natural weathering (over 3 years). The focus is put on functionality (visual influences) and durability (surface properties of the concrete).

Authors: Guruprasad C. N. , Shankareswari T. R. , Jeethu Maria Thomas , Basavarajappa Suman
Published: August 2021

Papillon–Lefevre syndrome (PLS) is an autosomal recessive genetic disorder caused by a deficiency in Cathepsin C. It is characterized by palmoplantar keratosis and premature loss of both primary and permanent dentition. Patients are often edentulous at an early age. Other symptoms include increased susceptibility to infections. Various etiologic factors such as genetic mutations, immunologic alterations, and bacteria have been implicated. We present a case report of 12-year-old female who reported to the dental clinic with a history of pain and swollen gums. Family history revealed consanguinity. On clinical examination, there was palmoplantar keratosis and examination of the oral cavity showed generalized periodontal pockets, tooth mobility, and periodontal abscess. Radiographic examination revealed generalized horizontal bone loss. Lateral cephalogram revealed retarded somatic development. A diagnosis of PLS was arrived based on history, clinical and radiological findings. Nonsurgical periodontal treatment along with the treatment of skin lesions was performed. A combined and intensive mechanical and antimicrobial treatment with supportive periodontal treatment in PLS patients may halt the periodontal disease progression. The dentists should be aware of the same because an early diagnosis of the syndrome can help to preserve the teeth by the timely institution of treatment, using a multidisciplinary approach.

Authors: Ponnusamy Prashanth , Borthakur Bikash Jyoti , Ganesan S. , Swathika B.
Published: August 2021

Background:

The capacity of an irrigant to dissolve pulp tissue is of paramount importance as it can clean areas of the root canal that are inaccessible to instrumentation.

Aim:

To evaluate the tissue dissolving capacity of sodium hypochlorite (NaOCl) and peracetic acid (PAA) in combination.

Materials and Methods:

Forty maxillary central incisors were split longitudinally and grooved to mimic lateral canals. Pulp retrieved from freshly extracted impacted third molars were placed in grooves and repositioned in a putty index. All samples were irrigated with four different irrigants. 3% NaOCl; 1% PAA; 3% NaOCl and 1% PAA and Normal saline. Samples were irrigated for 5, 10 and 15 min weighed before and after each cycle with precision balance. Statistical analysis with ANOVA and post hoc Bonferroni was performed.

Results:

All groups showed tissue dissolution, except Group IV (Negative control). Complete dissolution did not occur in any sample. Group III showed statistically significant difference at 10 min.

Conclusion:

Results suggested that NaOCl and PAA in combination have better tissue dissolving capacity than used individually.

Published: August 2021

Background:

The presence of microorganisms as a result of failure to properly disinfect the canal is the most common cause of pain. Thus, the main focus of endodontic therapy is on maximum elimination of these bacteria. Intracanal medicaments have been advocated as inter appointment dressings to eliminate the remaining bacteria after root canal preparation and reduce periapical inflammation of tissues. Aims and Objectives: The aim of this study is to evaluate the effectiveness of calcium hydroxide, triple antibiotic paste and corticosteroid antibiotic paste as an intracanal medicament in pain reduction.

Materials and Methods:

One hundred and twenty patients with a chief complaint of pain and planned for root canal treatment were randomly selected and were further divided into four groups. Group I (n-30) - control group, Group II (n-30) - receiving calcium hydroxide, Group III (n-30) - receiving triple antibiotic paste and Group IV (n-30) - receiving corticosteroid- antibiotic paste (Ledermix) as an intracanal medicament. Pain was measured using visual analogue scale (VAS). The scores were recorded preoperatively, at 24 hours, 48 hours and 72 hours. The result was tabulated and statistically analysed.

Results:

At baseline, the mean score pain for all four groups were in the same range. There was no statistically significant difference between the preoperative mean pain score values. Group IV showed the highest pain reduction followed by Group III, Group II and Group I respectively.

Conclusions:

Under the conditions of this study, painful single rooted teeth that had been dressed with Ledermix paste showed higher pain reduction than the other three groups.

Indian Debates on the International Left: Selected Writings of Lajpat Rai
Authors: Rai Shirin , Prakash Anand
Published: August 2021

This book traces the Indian Left’s engagement with the international communist debates of the 1960s and 1970s, shedding new light on the fault lines within the Left as well as on its international solidarities. Lajpat Rai argued for rethinking established leftist positions, seeking inspiration in experiment and developing creative approaches for the sustainability of socialist ideas and ideals. The contemporary relevance of these debates is significant as the Left remains without a sharp response to the rise of neoliberalism and right-wing populism in India, and a failure of the Left to recognize the challenges emanating from a strongly integrated and organized finance capital on the one hand and the increasingly self-aware identity politics on the other. Democratic opposition rather than a bureaucratic thinking needs to be the backbone of any meaningful Left struggle. Lajpat Rai’s passionate writing gives expression to the spirit and intensity of political debates at the time and the role of the Left intelligentsia in comprehending, from a committed socialist angle, the shifting paradigms of an unstable world to help bring about progressive change.

Published: August 2021

Objective: The microanatomy of the fronto-ethmoidal transition region has been addressed in several classifications. CT stereoscopic imaging (3DCTSI) provides improved display and delineates three defined complex “spaces”, the Frontal Sinus/Frontal Recess Space, the Infundibular Space of the Ethmoid Uncinate Process, and the Ethmoid Bulla Space (FSRS, IS-EUP, EB), none of which were adequately described with the “cell” terminology. We present details on the 3D microanatomy, variability, and prevalence of these spaces. Methods: 3D stereoscopic imaging displays (3DCTSI) were created from 200 datasets. The images were analyzed and categorized by a radiologist (SJZ), and consultant otolaryngologists, focusing on 3D microanatomy of the fronto-ethmoidal transition, the frontal recess/frontal sinus, and drainage pathways, in comparison to established anatomical classification systems. Results: The anterior ethmoid is subdivided into seven groups with the following core properties and prevalence: 1. The horizontal roof of the IS-EUP is attached to the superior half of the frontal process of the maxilla (19%); 2. The IS-EUP extends into the frontal recess (6.5%); 3. The IS-EUP extends into the frontal recess and the frontal sinus (18.5%); 4. A bulla is seen in the medial frontal sinus (3%); 5. The ethmoid bulla and supra bullar space extend into the frontal sinus (7%); 6. Lamellae extend into the FSRS antero-superiorly (25%); 7. FSRS expansion expands below the upper half of the frontal process of the maxilla (FSRS) (21%). Conclusion: 3-D analysis of the detailed anatomy provides important new anatomic information with the increased focus on precision surgery in the region.
Optimization of Exhaust Muffler Design Variables for Transmission Loss Using Coupling of modeFRONTIER and GT-POWER
Authors: Hiwale Diwakar , Bijwe Vilas , Vaidya Rohit , Chavan Yuvraj
Published: August 2021

Exhaust Noise attenuation is one of the important functions of exhaust muffler. Transmission Loss (TL) is a measure of noise attenuation used in designing exhaust mufflers for NVH. TL is a logarithmic difference between inlet and outlet pressures for unit velocity input at inlet of the muffler and anechoic termination at outlet of the muffler as boundary conditions. TL amplitude and its frequency tuning depends on a combination of various muffler design parameters like volume, length, muffler cross section, pipe cross sections, pipe perforations, number of chambers, baffle perforations, etc. Achieving the desired TL performance with no valleys over a wide frequency range is very challenging. Manual design iterations with large numbers of permutations and combinations of design variables are difficult and time-consuming. It also needs a highly experienced professional to balance TL performance, design variables and design constraints. The current paper discusses an exhaust muffler TL optimization simulation process that couples modeFRONTIER for DOEs, & GT-POWER, for acoustic simulation. All identified design variables are iterated in batch mode within specified design limits. DOEs are set up using Non-dominated Sorting Genetic Algorithm (NSGA) or Multi Objective Genetic Algorithm (MOGA) in modeFRONTIER. Based upon pre-defined iterative simulation cycles, muffler design is optimized to meet design constraints and TL performance. This optimization helps to reduce manual efforts in building simulation models, to carry out more iterations, to reduce solver time, to reduce manual intervention for post processing, and to give optimized TL performance.
A New System for the Measurement on Small Samples of the Normal-Incidence Insertion Loss of Acoustic Multilayers
Authors: Ruggeri Giulio , Bertolini Claudio , Di Marco Federico
Published: August 2021

This article presents a new system for the measurement on small samples of the normal-incidence Insertion Loss (IL) of multilayers used for the manufacturing of automotive sound package parts. The system consists of a rigid piston connected to an electrodynamic shaker and facing a tube positioned just above it. The measurement principle is based on the evaluation of the Transfer Matrix (TM) of the piston-and-sample assembly, from which the desired IL can be calculated. The TM can, in turn, be evaluated from the measurement of the piston velocity and of the acoustic pressure inside the tube, with two different tube termination conditions.

The proposed measurement system is first of all aimed at simplifying the assessment of the acoustic insulation of multilayers used for the manufacturing of sound package parts. In the automotive field, this assessment is customarily done by measuring the diffuse-field Insertion Loss (IL) of flat samples having an area of around 1m2 in two-chambers facilities. A kind of test that, while being well-established, may be quite demanding and resource-consuming, in particular when many different multilayers (different materials, different constructions, different layers’ thickness, etc.) have to be compared. With the proposed system, the amount of material and the time needed for a test is strongly reduced compared to this standard practice. Furthermore, the system intends to overcome the limitations of the 4-microphones test procedure based on the ASTM E2611 standard that cannot provide the actual IL of a package (but only its TL, without any support) and that suffers from the influence that samples’ edge conditions may have on the results.

In a first part, the article first discusses the principles on which the measurement system is based. In a second part it focuses on some aspects of the measurement hardware that are particularly delicate (e.g. sample’s edge conditions). Eventually, the article describes how a prototype of the measurement system was built and validated.
A Hybrid Acoustic Model for Composite Materials Composed of Fibers and High Surface Area Particles
Authors: Mo Zhuang , Shi Tongyang , Lee Seungkyu , Seo Yongbeom , Bolton J. Stuart
Published: August 2021

High surface area particles have drawn attention in the context of noise control due to their good sound absorption performance at low frequencies, which is an advantage compared with more traditional materials. That observation suggests that there is a good potential to use these particles in various scenarios, especially where low frequency noise is the main concern. To facilitate their application, composite materials are formed by dispersing particles within a fiber matrix, thus giving more flexibility in positioning those particles. In this work, a hybrid model that combines a model for limp porous materials and a model of high surface area particles is proposed to describe the acoustic performance of such composites. Two-microphone standing wave tube test results for several types of composites with different thickness, basis weight, and particle concentration are provided. An optimization procedure based on the particle swarm algorithm is introduced to identify the input parameters of the proposed model by minimizing the difference between measured and predicted absorption coefficients. Comparisons between the model predictions made using the optimized parameters and the measurements are shown in this paper, which demonstrates that the proposed model can predict the acoustic performance of the composites with reasonable input parameters.
The Influence of Hotel Customer Demographics Differences on Customer Perceptions
Authors: Juliana  , Hubner Ira , Sitorus Nova , Pramono Rudy , Pramezwary Amelda
Published: August 2021

The aim of this research was to build a conceptual model by analyzing the influence of customer demographics (age, gender, status, culture and profession) on guest perceptions (customer perceived value, perceived fairness, willingness to pay) of hotel room prices during the COVID-19 pandemic. The respondents of the study were the guests who had stayed twice at a budget hotel in Indonesia in the last twelve months. The study used a purposive sampling technique, and SPSS ANOVA was used in order to analyze the descriptive statistics on customer demographics and PLS-SEM. The study findings reveal that customer demographics (gender, profession, and culture) significantly affect all three aspects of customer perceptions. Customer age is found to greatly impact the perceived fairness and willingness to pay (hypothesis is accepted). The relationship between customer age and customer perceived value is statistically insignificant and, in relation to customer status, does not have a significant affect on customer perceived value, perceived fairness, and willingness to pay (hypothesis is rejected). These findings can contribute towards future research on customer perceived value, fairness and willingness to pay and they also provide insight for more effective hotel pricing and marketing strategies.
Strategic Orientation, Corporate strategy and firm performance: The case of Wilderness Holdings Limited
Authors: Pansiri Jaloni
Published: August 2021

This study investigates the growth of Wilderness Holdings Limited from its inception in 1983 to its entry into international markets. Using document analysis, the study identifies strategic orientation, and new market entry as two major ‘tipping points’ critical to WHL growth. This study found that WHL used vertical integration, acquisitions, downscoping, strategic alliances and partnerships to propel new market entry into eight countries in Africa. Its growth over the years was complex and possibly unique to itself specifically in respect to how downscoping and acquisition can be used together to propel growth. From a loss of BWP4, 967,000 in 2009, WHL’s profits reached BWP62, 751,000 in 2018. While WHL’s strategy may not be copied, it is essential for firms to blend different strategies in a manner that would lead to growth. However, the limitation of the WHL’s strategy is that it ultimately leads to over-diversification, unless downscoping is equally intensified.
The structure and the list 3-dynamic coloring of outer-1-planar graphs
Authors: Li Yan , Zhang Xin
Published: August 2021

An outer-1-planar graph is a graph admitting a drawing in the plane so that
all vertices appear in the outer region of the drawing and every edge crosses
at most one other edge. This paper establishes the local structure of
outer-1-planar graphs by proving that each outer-1-planar graph contains one of
the seventeen fixed configurations, and the list of those configurations is
minimal in the sense that for each fixed configuration there exist
outer-1-planar graphs containing this configuration that do not contain any of
another sixteen configurations. There are two interesting applications of this
structural theorem. First of all, we conclude that every (resp. maximal)
outer-1-planar graph of minimum degree at least 2 has an edge with the sum of
the degrees of its two end-vertices being at most 9 (resp. 7), and this upper
bound is sharp. On the other hand, we show that the list 3-dynamic chromatic
number of every outer-1-planar graph is at most 6, and this upper bound is best
possible.
From Uprooting to Exclusion: First World War Refugees in the French Rural West
Authors: Richard Ronan
Published: August 2021

During the First World War, between 2 and 3 million people choose exile, chased away by the fights. In West of France, 150 000 evacuees, refugees or repatriates are in this way welcomed. From autumn 1914, their integration causes difficulties, minor at the beginning but which become more important from 1915. In a context of prolonged war which nobody has predicted, their sociocultural profile is quickly considered as incompatible with the expectations of native populations, mainly rural and unaccustomed to this “discovery of the difference.”

Durant la Première Guerre mondiale, entre 2 et 3 millions de réfugiés, chassés par les combats, choisissent l’exil. Dans l’Ouest de la France, 150 000 évacués, réfugiés ou rapatriés sont ainsi accueillis. Dès l’automne 1914, leur intégration suscite des difficultés, mineures au début mais qui s’accentuent à partir de 1915. Dans un contexte de guerre dont nul n’a prédit l’allongement, leur profil socio‑culturel est vite considéré comme incompatible avec les attendus de populations autochtones majoritairement rurales et peu accoutumées à cette « découverte de la différence ».
Expatriation as a Form of Emancipation. Towards a Different View of International Migration?

This paper seeks to analyze expatriation in a phenomenological perspective. It aims to question the usual analytical tools of human displacements. Thedeconstruction of social class, racial and national identities, allows us to highlight the emancipation of the individual from the patria. Expatriation appears like a heuristic existential notion to look differently at international migrations. This perspective unifies migratory situations beyond the implicit cleavages between tradition and modernity.

This research is motivated by the problems of students who fail to achieve happiness in their lives; this is caused by the inability of students to make adjustments to all forms of change in maintaining survival. Efforts that can be made to overcome this problem are to provide group guidance services with game techniques. This study aims to test whether the game technique in group guidance services is effective for improving students' self-adjustment. The method used in this research is experimental research using Pretest-Posttest Control Group Design. The results showed that there was a change in the mean value at the pre-test of 93.43 for the experimental class and 92.57 for the control class and the mean value at the post-test of 151.64 for the experimental class and 98.71 for the control class. So that the mean value at the time of post-test increased by 58.21 for the experimental group and 06.14 for the control group. These changes mean that group guidance with game techniques is empirically proven to be effective in increasing student adaptation

Authors: KASAPBAŞI Emine Esra
Published: August 2021

Su, havadaki gazlar ve uçucu organik kirleticilerin verimli fotokatalitik bozunması için,TiO2 (titanyum dioksit) esaslı katalizörlerin fotokatalitik uygulamaları önem taşımaktadır. TiO2 yapısı sadece UV-ışığı ile etkileşime girebilmesi nedeni ile güneş ışığındaki etkinliği azdır. Farklı atomlar ile (Fe, C, N, Se) katkılandırılarak veya iletken polimerler ile modifiye edilerek güneş ışığındaki etkinliklerinin arttırılması sağlanabilir. Atomlar ile katkılandırılmaları ile ilgili literatürde birçok çalışma yer almasına rağmen iletken polimerler ile modifiye edilmeleri son zamanlarda incelenmeye başlanmıştır.

Bu çalışmada da TiO2 pirol halkaları ile modifiye edilerek elde edilen kompozitlerin optik, elektronik yapıları, etkileşimdeki yüzeyleri ve PPy- TiO2 arasındaki yük transfer özellikleri DFT, TDDFT yöntemleri kullanılarak açıklanmaya çalışılmıştır. Yapılan hesaplamaların sonucunda TiO2 yüzey alanı arttıkça PPy-TiO2 arasındaki etkileşimlerin daha fazla olduğu ve elde edilen kompozitin fotokatalitik etkinliğinin yüksek olduğu gözlenmektedir.

Authors: Smith Misty
Published: August 2021

A service learning project was used to encourage social work student engagement with older adults, support a community need, and meet the course objectives, one being conducting a social work assessment. Paired with an older adult resident, students applied theoretical concepts to a practice experience to meet student learning outcomes and expand comfort levels. Fourteen students participated in the convergent-mixed methods study. Assessment scales regarding bias and knowledge were administered and written reflections were recorded. Findings suggest students experienced deeper learning from applying theory and skills and had a positive shift in perspectives of older adults through the service-learning experience.
The Strategy Project: An Exploration of Enhancing Self-Regulated Learning in an Introductory Psychology Course
Authors: Whittlesey Valerie , Steiner Hillary
Published: August 2021

College success requires development of self-regulated learning skills. This study describes a self-regulated learning strategy intervention in a large general education Introductory Psychology course, focusing on the second exam. Students' reflection responses across five time periods were compared with exam performance. Increased self-regulated learning strategies usage correlated with decreased passive learning strategies usage, increased hours of study, and increased academic performance. Strategy project interventions can be effective for introductory courses. However, because students may revert to passive strategies that worked in the past, strategy instruction should be extended throughout a course.
La procedencia de la ontología dualista: entre el proyecto de modernidad científica y el neoextractivismo
Authors: Sanz Ferramola Ramón
Published: August 2021

Este trabajo investiga el vínculo histórico-filosófico entre el proyecto que la modernidad epistemológica inaugura hacia principios del Siglo XVII y el neoextractivismo actual. Para ello, el trabajo historiográfico se convierte en búsqueda de la procedencia que, a diferencia de la historia tradicional, se abstiene de reproducir el pasado como mera justificación del presente. Se pretende mostrar la continuidad conceptual y económico-política entre el modo en que la ciencia clásica concibe la relación con la naturaleza devenida objeto y mecanismo, y por lo mismo mercancía. Este modo de pensar y hacer sobre la naturaleza queda sintetizado en la denominada “ontología dualista” en la que la potencia técnica de nuestros días, sin medir consecuencias en su búsqueda de la acumulación del capital, convierte a la propia ciencia-tecnología en fuerza geológica que desbarata el equilibrio bioterritorial entre seres humanos y no humanos, y produce un ecocidio que lleva al cambio climático. Este proceso epistemológico ha sido a la vez un proceso político, y se da en necesidad sincrónica con el colonialismo.

Cultural Sensitivity Beyond Ethnicity: A Universal Precautions Model
Authors: Gale Deborah
Published: August 2021

Cross-cultural healthcare research has grown exponentially in recent years, focusing primarily on the healthcare-related needs of ethnic and linguistic minorities. However, by approaching cultural sensitivity from an ethnic/linguistic perspective, the practitioner runs the risk of relying on essentialized or stereotyped accounts of cultural groups, as well as overlooking the needs of other groups (e.g., gays, elderly, physically challenged) that may validly be viewed as cultures and profitably studied with the tools of cross-cultural scholarship. This essay argues that Hofstede’s paradigm of cultural dimensions can serve as a useful foundation for providing culturally sensitive care following the model of Universal Precautions as a metaphor.
Electronic Clinical Records for Physiotherapists

Published: August 2021

Purpose: This pilot study compared traditional (paper-based) and electronic (computerized) clinical physiotherapy records. The content of the records and the software’s user acceptability were considered. Methods: A neuro-musculoskeletal patient scenario involving two encounters (initial and follow-up) was scripted and role-played to each of three experienced physiotherapists (A, B and C). Participants assessed the patient and made traditional clinical records. After basic training in an electronic record system, they repeated the assessments and made electronic records via a laptop computer. Three experienced physiotherapists (A, D and E) each used their usual method to write a clinical report and an electronic record to write a report with the aid of the software’s report tool. The two participants who wrote reports but did not assess the patient (D and E) received a brief software demonstration just prior to writing the electronic record report. The electronic and traditional clinical records and reports were compared regarding their content and completion time. Participants recorded their expectations and experience of learning and using the electronic record system via questionnaires. Results: Participants expressed initial apprehension regarding an unfamiliar documentation system, but generally found the electronic system easy to learn and use. Some would have preferred additional customization options. All traditional records contained pages that lacked patient identification details. The electronic records contained more details related to symptoms, social circumstances and physical examination findings. The participants used more time for assessment and recording the initial examination when using the electronic system. Participants reported easier data retrieval from the computerized records than from the traditional records. Conclusions:The electronic clinical record system may prompt more complete recording and facilitate better patient record identification. These effects have implications for patient care, communication between providers and clinicians’ medico-legal protection. Further research is needed to determine the system’s efficiency and to clarify the impact of other characteristics of electronic record systems for physiotherapists.
Medical Record Documentation: The Quality of Physiotherapy Entries
Authors: Phillips Anna , Stiller Kathy , Williams Marie
Published: August 2021

This study evaluated the standard of in-patient medical record documentation by physiotherapists at the Royal Adelaide Hospital (RAH), Adelaide, South Australia, during 2003. The impact of patient characteristics (ie primary diagnosis and length of stay in hospital) and physiotherapist features (eg employment classification level and years of employment at the RAH) on the standard of documentation was also explored. One hundred medical records were randomly selected for review and 224 physiotherapy entries were audited. The audit tool was based on the RAH Physiotherapy Department Guidelines for Documentation, which was comprised of five sections. Each section contained several items, which were scored as complete, incomplete, absent or not applicable. The total number of completed scores was calculated for each section of the audit form. A standard of 100 per cent completed was expected for the two sections containing those requirements considered mandatory according to the RAH Physiotherapy Department Guidelines, whereas a lower completion rate was considered acceptable for the remaining sections. The standard of documentation varied considerably, with only five items (4.3%) achieving a rate of 100 per cent completion, namely ‘date’, ‘heading physiotherapy’, ‘signature’, ‘page includes patient details’ and ‘after the first attendance’. In total, 94 items (81.7%) were at least 50 per cent completed, which was considered a reasonable overall standard. The patient diagnosis was the only patient or physiotherapist characteristic that significantly affected the standard of documentation (p = 0.03). While the overall standard of documentation was deemed acceptable, it was clear there was room for improvement.

Purpose: Based on a recently developed medical framework for informed shared decision-making (ISDM), three health and human service programs at the University of British Columbia conducted a combined two-stage project to: (1) develop an interprofessional ISDM-training workshop and (2) test its impact in field-placement clerkships for students in Pharmaceutical Sciences, Physical Therapy, and Occupational Therapy. Method: Sixteen senior year students from the participating disciplines were recruited to: (1) participate in a workshop to learn about ISDM, (2) observe multiple preceptor/patient encounters during their clerkships (3) record their observations in a field notebook, and (4) participate in a follow-up workshop to debrief their experiences and offer feedback. Results: Overall, students observed 145 encounters and coded their ability to detect the presence or absence of eight decision-making competencies in each encounter. Across the disciplines, students were more certain of some competencies (developing partnerships, negotiating decisions) than others (patient’s preferences for information, patient’s role in decision-making). Irrespective of competency, students in Physical Therapy were more hesitant to commit to certainty than other students. Analysis of student uncertainties, combined with training session debriefings provided guidelines for improving the ISDM training workshop and offered systematic instructional insights for working with students in these different disciplines.Conclusions: Despite their uncertainties, the majority of students reported that participation in the project provided them with a better understanding of ISDM and influenced the ways they would approach future communication with patients in their own practices to facilitate ISDM.
The Nature of Career Advice Provided to Undergraduate Allied Health Sciences Students at the University of South Australia
Authors: Williams Marie
Published: August 2021

Purpose: The purpose of this study was to investigate the nature of career advice, especially advice concerning postgraduate research training degrees, provided to and by students in five health professional bachelor’s degree programs at the University of South Australia. In addition, differences between professional disciplines in terms of career advice and knowledge of current research activities of staff and research degree students were explored. Method: A cross-sectional survey of final year students in five disciplines within the School of Health Sciences was used in this study. Information was sought on demographics, the nature of career advice received, advice the respondent would provide to a peer, and knowledge of current research activities. Differences between disciplines were calculated with respect to positive responses for advice for postgraduate study (Honours, Masters by Research or PhD) and knowledge of current research activities. Results: In 2004, 278 students completed the survey (response rate 82%). The majority of respondents (72%) indicated that career advice was provided throughout their degree. The most frequent career advice was related to postgraduate study (encouraged 28%, discouraged 27%) or work within a specific place of employment immediately upon graduation (encouraged 17%, discouraged 24%). Respondents from physiotherapy were significantly more positive in their responses concerning postgraduate study, experience of research courses, and knowledge of research activities. Conclusions: While generic advice was provided, there appears to be a lack of specific information relating to career progression and requirements for promotion within different modes of employment. Systematic evaluation of the relationships between career advice provision, employment choices and career progression is required specifically in the allied health professions.
