Published: September 2024

The integration of nanoparticles into plant cryopreservation protocols holds great promise for improving the survival rates and recovery potential of explants. This study aimed to verify the effect of nanoparticles on the ex-vitro performance of cryopreservation-derived plants. Lamprocapnos spectabilis (L.) Fukuhara (bleeding heart) ’Gold Heart’ and ’Valentine’ cultivars were used as the plant material. The encapsulation-vitrification cryopreservation protocol of shoot tips included the preculture, encapsulation, dehydration, storage in liquid nitrogen, rewarming, and recovery steps. Gold (AuNPs), silver (AgNPs), or zinc oxide (ZnONPs) nanoparticles were added at varying concentrations, either into the preculture medium or the protective bead matrix during encapsulation. After the in vitro recovery, the plants were transferred to the glasshouse and subjected to detailed biometrical, biochemical and cytogenetic analyses. Nanoparticles had no evident effect on the acclimatization efficiency (80–100% survival) and leaf number in L. spectabilis ‘Gold Heart’. Nonetheless, shoots developed from alginate beads supplemented with 5 ppm AuNPs were twice as long as the control, while the leaves of plants grown on the preculture medium with ZnONPs contained significantly more chlorophyll and had higher Leaf Soil-Plant Analysis Development (SPAD) values. Moreover, several NPs treatments stimulated the development of leaves, including their surface area, length, and perimeter. Higher ZnONPs levels enhanced also the replication process, resulting in higher nuclear DNA content. As for L. spectabilis ‘Valentine’, alginate augmentation with 5 ppm AgNPs or 5 ppm ZnONPs stimulated the elongation of shoots. There was also a tendency suggesting a positive influence of 5 ppm AgNPs in the alginate bead matrix on foliar growth. The effect of nanoparticles on the content of flavonoids, anthocyanins, and stress markers in the plants varied depending on the treatment and cultivar, but also on the organ studied (leaf or stem). Overall, L. spectabilis ‘Gold Heart’ was more stress-tolerant and genetically stable than ‘Valentine’ judging by the activity of Photosystem II (PSII) and flow cytometric analyses, respectively. The complex effects of nanoparticles on survival, biometric parameters, physiological responses, and cytogenetic events underscore the intricate interplay between nanoparticles and plant systems. Nonetheless, our research confirmed the positive effect of nanoparticles on the ex-vitro growth and development of L. spectabilis plants after cryostorage.

Published: September 2024

The purpose of this article is to discuss about the implementation of the trial of integrated marriage validity or isbat nikah terpadu. Based on the Supreme Court Regulation (Perma) No. 1 of 2015, despite Religious Court (PA), the implementation of integrated marriage validity involved the Office of Religious Affairs (KUA). From the perspective of maqāṣid al-sharī'ah, the integrated marriage validity can be considered as an effort of Indonesian government to realize public benefits (maṣlaḥat) as the essence of maqāṣid al-sharī'ah in thefield of marriage affairs. In a broader sense, the existence of the integrated marriage validity could be considered to be able to preserve the religion (ḥifdh al-din), the soul (ḥifdh al-nafs), the intellectual faculty (ḥifdh al-’aql), the offspring (ḥifdh al-nasl), and the property (ḥifdh al-māl).Artikel ini bertujuan untuk membahas tentang pelaksanaan sidang isbat nikah terpadu. Bedasarkan Peraturan Mahkamah Agung RI No. 1 tahun 2015, pelaksanaan isbat nikah terpadu melibatkan dua institusi, yaitu Pengadilan Agama (PA) dan Kantor Urusan Agama (KUA) tempat dilaksanakannya sidang isbat nikah tersebut. Dari persepektif maqāṣid al-sharī’ah, pelaksanaan isbat nikah terpadu dapat dianggap sebagai usaha Pemerintah untuk mewujudkan kemaslahatan umum sebagai inti dari maqāṣid al-sharī’ah dalam bidang perkawinan. Dalam konteks yang lebih luas, pelaksanaan isbat nikah terpadu dapat dikategorikan sebagai usaha nyata Pemerintah dalam menjaga agama (ḥifdh al-din), jiwa (ḥifdh al-nafs), akal (ḥifdh al-’aql), keturunan (ḥifdh al-nasl), dan harta (ḥifdh al-māl).
Military establishments of the Ottoman Empire in Koysinjaq (1850-1918)
Authors: Abdulsamad Zana T. , Taib Jamal F.
Published: September 2024

This study is concerned with Koysinjaq's military situation from the middle of the nineteenth century until the end of World War I. After the Kurdish emirate's authority ended, the city of Koysinjaq fell directly under the rule of the Ottomans; after settling there, they attempted to strengthen their authority. That was why they settled some military forces in there; that way, they directly impacted the city's overall situation. It appears that after Baban's rule ended, Koysinjaq lost its important political position. However, the military forces that came considered themselves the city’s guards; they intervened in its affairs, while the city did not need all those forces to protect it, as they were just burdens on it. The existence of these forces made Koysinjaq play a significant military role in the region for the Ottomans, especially in the context of the Ottoman efforts to impose military stability and confront external and internal threats. This study attempts to estimate the size of the Ottoman forces in Koysinjaq, including their reasons for coming, their effects on the town, and their role in the balance of power there and nearby.

Published: September 2024

Eleven trade union leaders, many familiar with basic occupational safety and health, but many not significantly trained in the field, received two weeks of disaster response training.  In zoom interviews they told of how their unions responded to such disasters as 9-11, the Covid-19 pandemic, and Hurricanes Sandy, Maria, and Harvey.  Unions, as is their historical practice, helped individuals, workplaces, and communities with resilience, but all participants said there needed to be much better at pre-disaster planning, training, and hard work to be able to respond adequately to future events.
Management's Perception of Succession Planning Towards Crafting a Succession Plan: The Case of a Higher Education Institution in Batangas
Authors: Calinao-De Guzman Twinkle M
Published: September 2024

People are an organization's most valuable resource; hence one must employ strategies that would increase these assets. While it is understood that these assets provide the organization’s competitive advantage, not much of their value is acknowledged. This study explored the management’s perception of succession planning as input for creating a succession plan. Specifically, this study determined the management’s perception in terms of the value and process of succession planning, its alignment with organizational culture, identified the resource needs to be considered, determined significant challenges to the effective implementation of a succession plan, and integrated data as inputs for the creation of succession plan. Qualitative research, specifically a case study, was utilized since the scope was limited to a specific organization. The nine management employees of the identified HEI were the study’s participants. Key informant interviews and documentary analysis were used in data gathering while triangulation was carried out to verify the credibility of results. Findings revealed that although management employees perceived succession planning as advantageous, they only had slight awareness of it. Cultural variables in management, resources, and systems generally impede the creation and implementation of a succession plan rather than support it. Further, the required KSAs of the identified talent pipeline and budgetary resources were significant considerations. Employee turnover, resource constraints, and the “padrino” system posed challenges to the effective implementation of a succession plan. Lastly, the analysis resulted in a crafted succession plan with the integration of a professional development plan spanning five years.

Published: September 2024

The study aimed to identify the level of some elements of physical fitness among female soccer players in Palestinian clubs, in addition to identifying differences in the level of fitness according to the variable years of playing: (1-2 years, 3 years or more). To achieve this, the researchers used the descriptive approach, using and conducting physical tests (speed, flexibility, endurance, agility, and muscular strength) on a stratified random sample of (89) emerging female soccer players. The results of the study showed that the level of physical fitness among young female soccer players in Palestinian clubs was good, as a function of the arithmetic average of the physical fitness elements, respectively: speed (8.9) m/s, flexibility (6.05) cm, endurance (2.39) m/min, Agility (14.7) m/s, muscular ability (1.45) meters. The results of the study showed that there are no differences in the level of some elements of physical fitness among female soccer players due to the variable years of playing. The researchers recommended the need for continuous training to improve and develop the level of physical fitness among female soccer players in Palestinian clubs.

Published: September 2024

Myostatin inhibition improves insulin sensitivity in preclinical and clinical models; however, studies investigating the relationship between serum myostatin levels and insulin sensitivity are discrepant. Sensitive and specific myostatin LC–MS/MS assays are now available to accurately assess serum myostatin level in vivo. We sought to determine whether higher serum myostatin levels are independently associated with lower insulin sensitivity in adults with overweight/obesity. Participants included 74 adults, 20–65 years old, BMI ≥25 kg/m2 without type 2 diabetes. Appendicular lean mass (ALM) was measured by dual‐energy x‐ray absorptiometry; visceral adipose tissue (VAT) was measured by computed tomography. Main outcome measures were serum myostatin levels (LC–MS/MS) and insulin sensitivity (Matsuda index). Mean age was 48 ± 12 years, and BMI was 33.1 ± 5.6 kg/m2 (mean ± SD). Men had higher mean serum myostatin levels versus women (8.3 ± 1.9 vs. 7.2 ± 1.9 ng/mL, p = 0.01) and higher serum myostatin levels were associated with higher ALM (R = 0.34, p = 0.003). Higher serum myostatin levels were associated with lower Matsuda index (R = −0.44, p = 0.0004), which remained significant after controlling for BMI, VAT, ALM, and sex. In conclusion, higher serum myostatin levels are independently associated with lower insulin sensitivity in adults with overweight/obesity and may be a marker of or play a mechanistic role in the development of insulin resistance.
A Comparative Analysis of the Use of the Discourse Marker “But” in a British Televised Political Interview Show: A Socio-Pragmatic Perspective
Authors: Fu Yanli
Published: September 2024

This research investigates the utilization of the discourse marker (DM) “but” by interviewees (IEs) from a socio-pragmatic standpoint, focusing on its frequency and function through the analysis of a corpus comprising political interviews aired on BBC’s HARDtalk. The IEs are categorized into three demographic cohorts: those from eastern versus western cultures, non-native English-speaking IEs versus native English speakers, and female IEs versus their male counterparts. The study employs both quantitative and qualitative methods. Quantitatively, no statistically significant difference is found in the overall frequency of “but” usage among the three groups. Qualitatively, the analysis reveals the polyfunctionality of the DM “but”, with the most prevalent function being “contrast”, consistently employed across all demographic cohorts, although lacking statistical significance. Additionally, statistically higher usage of various function types is observed among IEs from the western culture and native English speakers compared to their counterparts. Female IEs exhibit a statistically higher frequency in the deployment of the “topic” function than males. Overall, while the frequency and the use of the “contrast” function show no significant difference, the study highlights the nuanced impact of culture, first language, and gender on the multifaceted functions of the DM “but” in political discourse. These findings contribute to our understanding of how socio-pragmatic factors subtly shape the usage of discourse markers like the DM “but” among varied interviewee demographics, as well as its role in shaping public perception and political narratives within the context of political interviews.

Published: September 2024

The production of silver nanoparticles (Ag NPs) utilizing biological means with renewable resources is thought to be risk-free, environmentally benign, and safe. In this work, the capacity of Bauhinia variegata to produce Ag NPs was measured. Numerous methods, including UV–Vis spectroscopy, TEM, FTIR spectroscopy, and XRD, were employed for the analysis of the produced Ag NPs. Ag NP antimicrobial capacity has been examined through microtitreplate as well as agar well diffusion techniques. Ag NPs’ ability to scavenge free radicals at varying concentrations was assessed using the DPPH technique. The MICs were 1,000 µg·mL−1 against pathogenic microbes including Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans, while 500 and 250 µg·mL−1 were versus Bacillus subtilis and Escherichia coli, respectively. Silver showed an intriguing antioxidant capacity, achieving IC50 of 46.23 μg·mL−1. Additionally, Ag NPs demonstrated possible anticancer action when applied to the carcinoma cell lines Caco-2, with IC50 of 396.2 μg·mL−1 and cytotoxicity toward normal Vero cell lines with IC50 of 609.45 μg·mL−1. Furthermore, Ag NPs demonstrated a range of antibiofilm activities toward S. aureus (MRSA). In conclusion, Ag NPs biosynthesized via B. variegata show promise for a variety of safe biological applications.
Experiential constructions in Hindi: the encoding of perceptions and bodily sensations
Authors: Carnesale Lucrezia
Published: September 2024

In this paper, I offer a description of argument-structure constructions of experiential verbs in Hindi, analyzing their syntactic and semantic properties, with a focus on the encoding of two experiential subdomains: perceptions and bodily sensations, the two most semantically different experiential event types (Luraghi, Silvia. 2020. Experiential verbs in Homeric Greek, a constructional approach (Brill’s Studies in Language, Cognition and Culture 27). Boston: Brill; Malchukov, Andrej L. 2005. Case pattern splits, verb types and construction competition. In Mengistu Amberber & Helen de Hoop (eds.), Perspectives on cognitive science, competition and variation in natural languages, 73–117. Amsterdam: Elsevier; Tsunoda, Tasaku. 2015. The hierarchy of two-place predicates: Its limitations and uses. In Andrej L. Malchukov & Bernard Comrie (eds.), Valency classes in the world’s languages, vol. 2, 1597–1626. Berlin: De Gruyter Mouton). I rely on data taken from a corpus consisting of Hindi literary texts of the 20th century, interrogated through Sketch Engine and I follow the approach of Cognitive Construction Grammar (Goldberg, Adele. 1995. Constructions: A construction grammar approach to argument structure. Chicago & London: The University of Chicago Press; Goldberg, Adele. 2006. Constructions at work: The nature of generalization in language. Oxford: Oxford University Press; Hilpert, Martin. 2014. Construction grammar and its applications to English. Edinburgh: Edinburgh University Press). The paper is structured as follows: Section 1 is an introduction giving the aim of the paper with some remarks on methodological and theoretical issues. Section 2 is a preliminary introduction on the domain of Experience and its encoding strategies. In Section 3, I give some remarks on case in Hindi, and I discuss the semantic–syntactic interplay in the language and the concept of iconicity, which is central in the paper. In Section 4, I present Hindi data and their analysis, focusing firstly on perception verbs (Section 4.1) and then on bodily sensation verbs (Section 4.2). In the last section (Section 5), I draw some conclusions trying to give an account of the type-frequency of each pattern, in order to evaluate the possible semantic constraints of each construction, and I propose a constructionist explanation of the distribution of Hindi argument-structure constructions across the highly variable range of experiential events.

Published: September 2024

Italy was among the first countries in Europe to be heavily impacted by the outbreak of COVID-19. Northern Italy and Lombardy, in particular, were the most affected areas. In September 2021, the team of “AIS, the digital turn” (AISdt), a project whose objectives include collecting data in 50 locations in Italy, across Lombardy and Piedmont, resumed in-person data collection. Given the field of the investigation and the profile required for the informants (speakers over 60), the decision came only after a long examination of the right conditions and the necessary measures. The paper is intended as a reference text of field investigations amid the pandemic: based on the experience of the AISdt project, it recounts the preparation required by the new modality of fieldwork, the protocols put in place to ensure the safety of all participants before and during the interviews, and the response received from the informants.
Twenty-first-century light over the Indo-European homeland: triangulating language, archaeology and genetics
Authors: Bjørn Rasmus G.
Published: September 2024

The reviewed volumes represent the past and future of triangulating human prehistory. Both works address the integration of the knowledge embedded in the Indo-European group of languages into the interpretation of archaeological and genetic data, but approach this very differently. By enlisting the expertise of scholars from the three different fields, with 22 contributions from more than 40 scholars from more than 10 different countries, The Indo-European puzzle revisited is both a seminal work and a resounding commentary on the, by its very nature, limited perspectives voiced by Jean-Paul Demoule as a sole archaeologist author of his book The Indo-Europeans. The title of the former is based on the subtitle of Colin Renfrew's Archaeology and language: the puzzle of Indo-European origins (1987), another archaeologist's foray into historical linguistics.

Published: September 2024

A novel method for forming composite materials was investigated by incorporating activated carbon powder (ACP) as a reinforcing agent within a polylactic acid (PLA) matrix, utilizing the hand layup fabrication technique. The composite materials were synthesized by varying the weight percentages of the matrix and reinforcements, encompassing pure PLA as well as ratios of 90:10, 80:20, 70:30, 60:40, and 50:50. PLA is recognized for its biocompatibility and favorable thermomechanical properties, similar to conventional plastics. The incorporation of activated carbon powder, known for its remarkable aspect ratio, proved highly advantageous, yielding exceptional mechanical properties. Analysis revealed that the composite with a ratio of 90:10 wt% of carbon powder to PLA demonstrated significant improvements in tensile strength (26.8%), flexural strength (26.37%), impact strength (61.1%), compression strength (25%), and hardness (45.8%). Additionally, thermal analysis showed that the 90:10 wt% composite exhibited minimal weight loss and maximum heat flow sustainability at approximately 600 °C compared to other composite combinations. Morphological examination using field emission scanning electron microscopy unveiled a uniform distribution of activated carbon powder reinforcement within the matrix, actively contributing to the enhanced mechanical properties of the composite.

Published: September 2024

Nocardiopsis sp. strain LC-9 was isolated from freshwater sediments and explored for its varied bioactive traits. Initially, ethyl acetate extract of strain LC-9 at varied concentrations showed pronounced antibacterial activities. After column chromatography, fraction F2 and F3 of the extract were identified as prominent fractions in terms of antimicrobial activities with low minimum inhibitory concentration values. Antioxidant activities of fraction F2 and F3 revealed remarkable scavenging of free radicals with low IC50 values (DPPH – 417.86 ± 0.24 μg/mL, ABTS – 431.6 ± 0.90 μg/mL, and FRAP – 404.36 ± 0.18 μg/mL). Fractions F2 and F3 were further characterized by UV spectrum, Fourier transform infrared spectroscopy, nuclear magnetic resonance, and liquid chromatography-mass spectrometry, and were identified as Antimycin A and 4-hydroxybenzoic acid. The compounds were further tested for anticancer activity against MCF-7 cells. The MTT assay showed reduced viability of MCF-7 cells with an increase in concentration of compounds. The IC50 values for Antimycin A and 4-hydroxybenzoic acid were 9.6 ± 0.7 μg/mL and 20.8 ± 0.4 μg/mL, respectively. Staining techniques confirmed the apoptosis mechanism. Finally, molecular docking (against targeted proteins of bacteria, fungus, and cancer cells) and molecular dynamics confirmed the pharmaceutical efficacy of the purified compounds.

This study investigated the nutritional components of Castanopsis hystrix seeds and evaluated their potential commercial value, regarding multi-function management of C. hystrix plantations. The following nutritional components of Castanopsis hystrix seeds were determined according to national standards: starch, fat, protein, reducing sugars, and amino acids. The chemical composition of their 50% benzene-alcohol(v/v) extracts was analyzed by GC-MS. Results showed that the contents of water, starch, fat, protein, and reducing sugar in the seeds were 36.08%, 68.11 g/100g, 0.3 g/100g, 3.98 g/100g, and 0.75 g/100g, respectively. The total amino acid content in the seeds is 3.42 g/100g, containing 16 kinds of amino acids, with 8 essential amino acids, which amount to 1.09g/100g. The amino acid SRC value was 84.02, indicating high nutritional value. A total of 26 compounds were identified in the extract of these seeds, with the highest content of aldehydes. The main compounds were 5-hydroxymethylfurfural (23.37%), melezitose (15.88%), palmitic acid (9.04%), and stearic acid (5.23%). The above analysis indicates that Castanopsis hystrix seeds have high nutritional value, as well as potential antioxidant and anti-tumor properties, which may have the potential to be used in food and medicine fields, with broad application prospects.

Published: September 2024

In the production of wood fuel pellets, starch is frequently used as an additive to enhance bonding and durability. This study investigated the effectiveness of four different kinds of starches as additives, each at a concentration of 5% (dry basis), when combined with sawdust from Scots pine (Pinus sylvestris). The starches tested included plain wheat flour, hydrothermally treated wheat starch, wheat starch with amylose-like properties, and nearly pure amylopectin obtained from waxy rice flour. All pellets were produced at a die temperature of 100 °C using a Single Pellet Press, with varying moisture contents of 5%, 8%, 11%, and 14% (wet basis). The pellets were evaluated for compression work, back pressure, physical density, hardness, and moisture content. Additionally, chemical bonding was assessed using FT-IR spectroscopy. Compression energy was found to be influenced by moisture content, irrespective of starch utilization, and it decreased with increasing moisture levels, especially between 5 to 8% (wb). The inclusion of starch led to notably higher pellet hardness, with amylose yielding the hardest pellets, 34±3 kg when the moisture content was 11%. Based on this study, it is recommended to use hydrothermally treated wheat flour, as it consistently produced high-quality pellets.

An innovative approach was pursued for sustainable packaging design using Cycle Generative Adversarial Networks (CycleGANs), tailored for wood packaging engraving. The methodology includes four phases: user participatory design, assembly scheme design, detailed Finite Element Analysis (FEA) optimization, and computer numerical control (CNC) engraving production. Each phase targets sustainability from design to final product, minimizing environmental impact and economic costs. Emphasizing early user participation helps adapt designs to user needs and environmental standards. Innovations such as real-time updates of packaging patterns via cloud-based iterations and an FEA optimization system enhance durability and aesthetics. This approach improves the environmental footprint and recyclability of conventional wood packaging. The research aims to shift perceptions in the packaging industry towards more sustainable practices, showcasing the practical applications of advanced digital tools in traditional manufacturing. It offers a scalable model for integrating sustainability into packaging design, providing valuable insights and inspiring future innovations in environmentally friendly practices across the industry.

The sulfate process for bamboo pulp production encounters silicon interference during the pulping stage, necessitating desilication before the alkali recovery section. This study investigated the desilication of bamboo pulping black liquor (BPBL), demonstrating that silicon was removed effectively by adding Mg/Al compound desilication agent to the BPBL via burning at high temperature. The desilication extent can reach 84% when the desilication agent is added in the proportion of Mg/Al (magnesium sulfate and sodium metaluminate) in the ratio 1.25:0.75. Subsequently, less-silicon white mud (LSWM) can be prepared after black liquor (BL) combustion desilication. LSWM was compared with normal WM as a blank sample, and the morphology and physicochemical properties of two kinds of WM were characterized. X-ray diffractometry revealed that both types of WM are primarily composed of calcite crystalline CaCO3 and hydrated CaSiO3. Scanning electron microscopy, X-ray photoelectron spectroscopy, and particle size analysis demonstrated the reduced content of CaSiO3 generated in the LSWM. This result indicated that the Mg/Al compound desilication agent removed the silicon from the green liquor (GL), thereby reducing the residual silicon in WM. This reduction is beneficial to the calcination recovery and comprehensive utilization of WM.

Low nutrient use efficiency (NUE) of conventional chemical fertilizers has resulted in the loss of costly nutrients and related environmental implications. Consequently, enhancing crop productivity and nutrient use efficiency are major challenges. In this backdrop, a field experiment was conducted to study the impact of pine oleoresin (POR) and neem oil (NO) coated urea (CU) fertilizers on crop productivity and nutrient recovery efficiency in maize-wheat cropping system grown on Vertisols of central India. The treatment combinations were POR-CU and NO-CU at 100% and 75% of recommended doses of fertilizers (RDF); normal urea (100% RDF); and an unfertilized control. Two years results indicated that the increment in grain yields due to POR-CU and NO-CU applications were 18.8% and 11.7% for maize and 11.6% and 3.49% for wheat, respectively, over normal urea. The apparent recovery efficiency of N (REN) for POR-CU, NO-CU, and normal urea at 100% RDF were 65.8%, 64.2%, and 51.4% in maize and 43.2%, 37.0%, and 34.6% in wheat, respectively. There was no significant difference noticed between POR-CU and NO-CU with respect to grain yield and N recovery efficiency. Hence, the study suggested that POR-CU could be a possible alternative option to NO-CU for improving crop yield and NUE. However, further research is needed to determine how effective POR-CU is in diverse agricultural systems and climatic conditions.

OBJECTIVE

Postoperative communication errors contribute to patient harm and excess costs. There are no existing standards for postoperative handoff to the acute care inpatient unit. We aimed to compare the experiences and preferences of pediatric hospitalists and surgeons about the content and timing of this handoff.

METHODS

We conducted a cross-sectional multisite survey of pediatric hospitalists and surgeons at 4 hospitals using a novel survey tool developed through a systematic 7-step process. We collected data on the perceived frequency of communication for 37 handoff elements and how essential each element was for an ideal handoff. We used 5-point Likert scales of communication frequency and essentialness. Respondents identified perceived and preferred handoff timing. Mention frequency and timing data were analyzed with the Mann-Whitney U test and Fisher’s exact test, respectively.

RESULTS

Seventy hospitalists (61%) and 27 surgeons (25%) responded to the survey. Over half of both hospitalist and surgeon respondents rated 13 handoff elements a 5 on the essentialness Likert scale. Surgeons perceived that 33 handoff elements were mentioned significantly more frequently than perceived by hospitalists (P < .05). Of hospitalists, 58% preferred that handoff occur immediately before the patient leaves the postanesthesia care unit. Of surgeons, 60% preferred that handoff occur immediately postoperatively.

CONCLUSIONS

The 13 core elements we identified may facilitate the development of a standardized handoff checklist for postoperative communication between surgeons and hospitalists on acute care units. Areas of future study could include checklist validation, audits of handoff practice, and qualitative research on handoff preferences.

Authors: Drepper Laura
Published: September 2024

This article demonstrates the value of multiperspectivity in Design-Based Research. Design principles for the development of the learning environment Lesen mit Rätseln are based on scientific and didactic findings on reading literacy. The design was implemented in a primary school with 35 fourth-graders over 10 weeks (SJ 2022/23). Quantitative and qualitative data are analysed to reconstruct reading literacy from multiple perspectives about reading fluency, reading comprehension, reading motivation and self-concept of reading. The objective is to value new evidence of reading literacy at the end of primary school and to evaluate the learning environment Lesen mit Rätseln. The paper ends with three scientifically proven and empirically evaluated design principles. These design principles refer to Deci & Ryan (1985) and can be applied to German Didactics. Finally, the design principles indicate advice for practice.

Paradoja de los megaproyectos y gestión presupuestaria vial en Ecuador 2002-2006
Authors: Moreno Parra Iván Manuel
Published: September 2024

Partiendo de los sobrecostos del 80 % en el Chanel Tunnel entre Reino Unido y Francia, 220 % en el Big Dig de Boston, 1400 % en la Ópera de Sídney y casos similares alrededor del mundo, esta investigación, a diferencia de anteriores, analiza cómo el entorno afecta a un conjunto de proyectos de infraestructura en vez de aislar a cada uno para luego estudiarlo, respondiendo a la siguiente pregunta: ¿Entre 2002 y 2006, una normativa presupuestaria de perspectiva anual afectó a los proyectos viales ecuatorianos? Así, se identificaron sobrecostos, retrasos en el cronograma de obra y déficit de beneficios estimados (adicionales a los de estudios anteriores) derivados de una gestión presupuestaria que no establecía el límite de recursos disponibles en el mediano plazo, permitiendo a los políticos tomar los recursos requeridos por los proyectos viales en ejecución para financiar nuevos.

Wprowadzenie i cel: Rak szyjki macicy jest czwartym najczęściej występującym nowotworem na świecie wśród kobiet według danych Światowej Organizacji Zdrowia z 2022 roku. Nowotwór ten jest uleczalny, jednak istotnym warunkiem jest jego wykrycie na wczesnym etapie i szybkie wdrożenie odpowiedniego leczenia. Celem pracy była analiza poziomu wiedzy pacjentek korzystających z opieki Gabinetów Specjalistycznych „Volumed” w Krakowie na temat szczepień przeciwko HPV. Materiał i metody: W badaniu wzięły udział 153 pacjentki Gabinetów Specjalistycznych „Volumed” w wieku 18–70 lat. Największa grupa badanych miała wykształcenie wyższe oraz zamieszkiwała miasta powyżej 500 tys. mieszkańców. Pacjentki wypełniały kwestionariusz ankiety zawierający 23 pytania zamknięte z możliwością udzielenia jednej bądź kilku odpowiedzi. Wyniki: Większość badanych (92%) miała wiedzę na temat szczepień przeciwko HPV. Mimo to co czwarta nie chciała zaszczepić swojego dziecka. Kobiety w trudnej i średniej sytuacji socjoekonomicznej częściej nie wiedziały o istnieniu szczepionki przeciwko HPV. Wnioski: Co czwarta kobieta w ankietowanej grupie nie chciała zaszczepić swojego dziecka przeciwko HPV. Spośród nich 83% dysponowało wiedzą na temat szczepienia. Sytuacja socjoekonomiczna kobiet miała wpływ na ich wiedzę o istnieniu szczepionki przeciwko HPV. Znajomość powikłań zakażenia HPV, innych niż rak szyjki macicy, jest niedostateczna i jedynie kobiety z wyższym wykształceniem dysponowały odpowiednią wiedzą w tym zakresie. Niewielki odsetek kobiet miał informacje dotyczące zasad bezpłatnego programu profilaktycznego raka szyjki macicy.
