Child Cognitive Development and Parent Roles: A Preliminary Comparison of Moroccan Parents to United States and United Kingdom Benchmarks
Authors: Karam Rita T. , Zellman Gail L. , Perlman Michal 
Published: February 2023

AbstractThere is a dearth of research examining what parents in MENA region know about children’s brain development and the type of activities they engage their young children at home to promote their cognitive development. This article describes and compares the views and behaviors of parents with children 0–6 years old from Casablanca, Morocco, the US, and the UK on early parental engagement. Seventy-eight Moroccan parents were compared to 1066 US/UK parents. The study utilizes survey data and explores parents’ understanding of and support for their children’s early cognitive development. Results reveal that more than fifty percent of Moroccan parents do not see themselves as having an impact on brain development until after the first year of their child’s life compared to 10% of US parents, in part because they believe that babies’ capacity for learning in the earliest years is limited. Yet Moroccan parents reported higher frequencies of teaching their young children letters and numbers and reading a book to them than US parents. These differences in at-home teaching practices may reflect the higher percentage of US/UK children who participate in early learning programs outside their own homes; such programs are not culturally accepted in Morocco. The belief that there is little capacity for learning in children’s earliest years among Moroccan parents may minimize parents’ motivation to function as their child’s first teacher in the absence of early education programs. Policy implications and interventions are discussed concerning ways to change parents’ knowledge and beliefs to motivate early learning activities.

AbstractIn this paper, we develop a three-stage stochastic network-based optimization model for the provision of 5G services with Unmanned Aerial Vehicles (UAVs) in the disaster management phases of: preparedness, response and recover/reconstruction. Users or devices on the ground request services of a fleet of controller UAVs in flight and the requested services are executed by a fleet of UAVs organized as a Flying Ad-Hoc Network and interconnected via 5G technology. A disaster scenario can create difficulties for the provision of services by service providers. For this reason, in the first stage, service providers make predictions about possible scenarios in the second stage. Therefore, the first stage represents the preparedness phase, the second stage represents the response phase, followed by the recovery/reconstruction phase, represented by the third stage. In each of the three stages, service providers seek to maximize the amount of services to be performed, assigning each service a priority. They also aim to, simultaneously, minimize the total management costs of requests, the transmission and execution costs of services, the costs to increase the resources of the pre-existing network and, if need be, to reduce them in the recovery/reconstruction phase. For the proposed multi-stage stochastic optimization model, we provide variational formulations for which we investigate the existence and uniqueness of the solution. Finally, a detailed numerical example is solved in order underline some of the key aspects of the model. This paper adds to the literature on the rigorous mathematical modeling of advanced technologies for disaster management.
When Attentional and Politeness Demands Clash: The Case of Mutual Gaze Avoidance and Chin Pointing in Quiahije Chatino
Authors: Mesh Kate , Cruz Emiliana , Gullberg Marianne 
Published: February 2023

AbstractPointing with the chin is a practice attested worldwide: it is an effective and highly recognizable device for re-orienting the attention of the addressee. For the chin point to be observed, the addressee must attend carefully to the movements of the sender’s head. This demand comes into conflict with the politeness norms of many cultures, since these often require conversationalists to avoid meeting the gaze of their interlocutor, and can require them to look away from their interlocutor’s face and head. In this paper we explore how the chin point is successfully used in just such a culture, among the Chatino indigenous group of Oaxaca, Mexico. We analyze interactions between multiple dyads of Chatino speakers, examining how senders invite visual attention to the pointing gesture, and how addressees signal that attention, while both participants avoid stretches of mutual gaze. We find that in the Chatino context, the senior (or higher-status) party to the conversation is highly consistent in training their gaze away from their interlocutor. This allows their interlocutor to give visual attention to their face without the risk of meeting the gaze of a higher-status sender, and facilitates close attention to head movements including the chin point.Abstracts in Spanish and Quiahije Chatino are published as appendices.Se incluyen como apéndices resúmenes en español y en el chatino de San Juan Quiahije.SonG ktyiC reC inH, ngyaqC skaE ktyiC noE ndaH sonB naF ngaJ noI ngyaqC loE ktyiC reC, ngyaqC ranF chaqE xlyaK qoE chaqF jnyaJ noA ndywiqA renqA KchinA KyqyaC.

AbstractThe period of adolescence brings with it a dynamic interaction between social context and behaviour, structural brain development, and anxiety and depressive symptoms. The rate of volumetric change in the ventromedial prefrontal cortex (vmPFC) and amygdala have been implicated in socioemotional development in adolescence; typically, there is thinning of grey matter volume (GMV) in the vmPFC and growth in the amygdala during this time. The directionality of the associations between social, emotional, and neuroanatomical factors has yet to be untangled, such as the degree to which social variables impact regional brain development, and vice versa. To add, the differences between sexes are still up for debate. In this study, longitudinal associations between peer problems, family support, socioeconomic stress, emotional symptoms, amygdala volume, and vmPFC GMV were investigated for both sexes using latent change score models. Data from a multi-site European study at baseline (mean (SD) age = 14.40 (0.38) years; % female = 53.19) and follow-up 2 (mean (SD) age = 18.90 (0.69) years, % female = 53.19) were used. Results revealed that peer problems did not predict emotional symptoms, rather they changed together over time. For males only, there was positive correlated change between vmPFC GMV, peer problems and emotional symptoms, indicating that slower vmPFC GMV thinning was associated with poorer social and emotional functioning. Additionally, greater family support at age 14 years was associated with slower growth of amygdala volume between ages 14 and 19 years for males; previous research has related slower amygdala growth to resilience to mental health disorders. The findings have extended understanding of mutual social, emotional and brain development, and avenues to protect mental health.

AbstractScorpion venom contains various peptides that could be utilized to treat various diseases, including cancer. This study aimed to evaluate the anti-cancer activity of scorpion venom peptide (Smp24) using a solid Ehrlich Carcinoma (SEC) mice model. SEC model was established by subcutaneous transplantation of SEC cells into Swiss albino female mice afterward subcutaneous injection of the Smp24 peptide compared to 5-Fluorouracil (5-FU) as a standard drug. Various biochemical, hematological, histopathological, immunohistochemical, and molecular (western blotting and RT-PCR) assays were performed to evaluate the antitumor activity of Smp24. Results revealed that Smp24 peptide significantly reduced tumor volume. Interestingly, Smp24 peptide significantly restored normal body functions in cancer-treated groups by maintaining HB, RBC’s, and WBC’s levels, reducing the elevated serum ALT and AST, and increasing total protein and albumin as well as enhancing antioxidant status through reducing the level of MDA and NO and elevating GSH, SOD, and CAT levels. Moreover, it restored the normal morphology of the liver and kidney tissues and improved hematological parameters in cancer-treated animals. Smp24 induced apoptosis in SEC cells, through upregulation of caspase-3 and BAX and the downregulation of VEGF, Bcl-2, p53, PCNA, and Ki67. Moreover, results exhibited the apoptotic and antiangiogenic effects of Smp24 against SEC cancer cells. These findings supported our previous results about the anti-cancer efficacy of Smp24 and made it a good candidate for developing effective and safe anti-cancer agents.

Published: February 2023

AbstractThere are growing expectations in Australia and internationally that school educators will engage with and use research to improve their practice. In order to support educators to respond to such expectations, there is a need to be able to accurately assess the levels of educators’ research engagement. At present, however, few psychometrically sound instruments are available. Drawing on two studies of Australian educators (n = 1,311) and utilising Rasch analysis, supported by confirmatory factor analysis, this paper reports on the development of a brief eight-item scale that demonstrates validity and reliability and evidenced unidimensionality in the second study. The scale is intended as a quick, easy-to-use tool for educators to gain insights into their beliefs about the value of engaging with research, their actions around using research, and their confidence in finding, interpreting, and judging the quality of relevant research. Notwithstanding the need for further testing, this paper argues that the scale has the potential to be applicable to other educational contexts and to contribute to future research into educators’ research engagement and its assessment. The scale can also provide school and education system leaders, as well as evaluators and researchers, with data regarding educators’ research engagement over time, allowing for research use supports and resources to be better targeted.
Shed light on photosynthetic organisms: a physical perspective to correct light measurements
Authors: Walter Andreas , Schöbel Harald 
Published: February 2023

AbstractThe requirements for novel and innovative production systems expedite research on light emitting diode-based illumination in a life science context. In course of these rapid developments, the scientific community is in need of a consensus regarding to the characterization and presentation of the applied lighting conditions. This publication aims to establish a basic understanding of photon physics and propose guidelines for the conclusive usage of light related quantities. To illustrate the challenges in data handling, six different light sources were measured and characterized. Furthermore, a stepwise conversion within and in-between physical systems is presented, and an opportunity to extract information from weak data sets is demonstrated. The proposed calculations indicated flexibility in data handling, but revealed partial inaccuracy for colored light emitting diodes with spectral power distribution maxima far-off 550 nm compared to spectrometer-based measurements and conversions. Furthermore, it could be shown, that when comparing light properties, the determination of photometric quantities is incorrect to describe lighting systems for photosynthetic organism and the usage of luxmeter or similar photometric sensors should be avoided. The presented guidelines shall support scientists in applying a consistent and precise characterization of their illumination regimes, tailored to their requirements to avoid ambiguous communication and the generation of incorrect and thus incomparable data based on wrong quantities and units, such as lumen or lux, in future research.
“Welcome to the Revolution”: Promoting Generational Renewal in Argentina’s Ni Una Menos
Authors: Friedman Elisabeth Jay , Rodríguez Gustá Ana Laura 
Published: February 2023

AbstractDespite the global upsurge of youth-fueled mass mobilization, the critical question of why new generations may be eager to join established movements is under-explored theoretically and empirically. This study contributes to theories of feminist generational renewal in particular. We examine the longer-term movement context and more proximate strategies that have enabled young women to participate steadily in a cycle of protest, alongside more seasoned activists, due to a process of feminist learning and affective bonding that we call “productive mediation.” We focus on the Argentine Ni Una Menos (Not One Less) massive yearly march, which, since its onset in 2015, demonstrates that feminist activists have achieved the sought-after goal of fostering a highly diverse mass movement. These large-scale mobilizations against feminicide and gender-based violence gain much of their energy from a strong youth contingent, so much so that they have been called “the Daughters’ Revolution.” We show that these “daughters” have been welcomed by previous generations of feminist changemakers. Drawing on original qualitative research featuring 63 in-depth interviews with activists of different ages, backgrounds, and locations across Argentina, we find that long-standing movement spaces and brokers, as well as innovative frameworks of understanding, repertoires of action, and organizational approaches, help to explain why preexisting social movements may be attractive for young participants.

Systematic literature review on technological transformation in SMEs: a transformation encompassing technology assimilation and business model innovation
Authors: de Mattos Camila Silva , Pellegrini Giustina , Hagelaar Geoffrey , Dolfsma Wilfred 
Published: February 2023

AbstractSmall and medium-sized enterprises (SMEs) are pushed to introduce new technologies due to different requirements and changes in the business setting. The SMEs' transformation to exploit new technologies is challenging given their lack of resources and the complexity of technological transformation, which encompasses technology assimilation and business model innovation (BMI). Although studies recognize the complementarity of technology assimilation and BMI for benefiting from technology, the literature is fragmented, and the technological transformation phenomenon remains abstract, especially in the SMEs' context. To improve understanding of technological transformation in SMEs, a systematic literature review was performed on 165 peer-reviewed papers published from 1999 to 2022, building upon BMI and technology assimilation constructs. The descriptive analysis outlines the field's evolution in terms of research and technological trends. The content analysis shows that: most papers focus on factors; the literature falls short of providing theoretical conceptualization and guidelines for the technological transformation process; only a few studies are dedicated to assessing the outcomes of technological transformation in SMEs; and the papers suggest that SMEs present a low transformation level. Finally, we inductively built a framework for technological transformation and suggest five research avenues.
Pot study using Chlorophytum comosum plants to biomonitor PAH levels in domestic kitchens
Authors: Hubai Katalin , Kováts Nora , Eck-Varanka Bettina , Teke Gábor 
Published: February 2023

AbstractIn indoor environments, cooking is a major contributor to indoor air pollution releasing potentially harmful toxic compounds such as polycyclic aromatic hydrocarbons. In our study, Chlorophytum comosum ‘Variegata’ plants were applied to monitor PAH emission rates and patterns in previously selected rural Hungarian kitchens. Concentration and profile of accumulated PAHs could be well explained by cooking methods and materials used in each kitchen. Accumulation of 6-ring PAHs was characteristic in the only kitchen which frequently used deep frying. It also should be emphasized that applicability of C. comosum as indoor biomonitor was assessed. The plant has proven a good monitor organism as it accumulated both LMW and HMW PAHs.
Social Policies and Theories on Quality of Life under COVID-19: In Search of the Missing Links
Authors: Shek Daniel T. L. , Leung Janet T. Y. , Tan Lindan 
Published: February 2023

AbstractCOVID-19 has generated many negative impacts on the family, including impaired psychological well-being of family members (parents and children) and family processes (such as parenting and family functioning). Regarding social policies to support families under the pandemic, there are several missing links. First, COVID-19 related policies mainly focus on physical well-being with a relatively weaker emphasis on psychological well-being. Second, with social policies primarily aiming at stabilizing the “financial capital” of the public, human capital (particularly personal resilience) and social capital (particularly family resilience) are relatively neglected. Third, while “general” social policies may help “averaged” individuals and families, there is a need to take pre-existing family vulnerabilities (such as poverty and caregiving burdens) and inequalities into account when formulating “down to earth” social policies. Fourth, while social science knowledge and theories have important potential contributions to help develop relevant policies and services to promote quality of life under COVID-19, explicit utilization is not strong. With reference to these missing links, we proposed several research and practice directions for the promotion of quality of life under the pandemic.
Intrapersonal capacities for sustainability: a change agent perspective on the ‘inner dimension’ of sustainability work
Authors: Ayers James , Missimer Merlina , Bryant Jayne 
Published: February 2023

AbstractAn ongoing discussion in education for sustainable development (ESD) research has focused on defining a list of agreed upon sustainability competencies required for the work of sustainability change agents. This discussion has included the consideration of an ‘Intrapersonal’ perspective that considers the role of inner qualities in change agents and how this impacts their ability to implement sustainability. While many researchers have looked at the ‘inner dimension’ of sustainability work, the identification and function of an ‘Intrapersonal’ competence remains in question. Utilizing practitioner responses, this paper identifies eight Intrapersonal capacities that change agents described as beneficial to their implementation of sustainability. These capacities are the ability to: Hold complexity, Foster a learner’s mindset, Deeply value others, Let be, Show up as one’s full self, Regulate and manage the self, Persist with lightness and Ensure one’s wellbeing. The study provides insights into the identification of the capacities and their relationship to a wider Intrapersonal research field. It also discusses the implications this perspective has on education for sustainable development should it consider incorporating such capacities into teaching and learning. While much literature in the field is of conceptual nature, this paper offers an empirical contribution by including the voice and perspective of change agents to the Intrapersonal discussion.

Published: February 2023

Abstract
Purpose
With the obesity epidemic, the number of bariatric procedures is increasing, and although considered relatively safe, major postoperative complications still occur. In cancer surgery, major complications such as reoperations have been associated with deteriorated mid/long-term outcomes. In obesity surgery, the effects of reoperations on postoperative weight loss and associated comorbidities remain unclear. The aim of this study was to assess mid-term weight loss and comorbidities following early reoperations in obesity surgery.

Methods
A population-based cohort study was performed within the Dutch Audit for Treatment of Obesity (DATO), including all patients that underwent a primary gastric bypass procedure or sleeve gastrectomy. Follow-up data was collected up until 5 years postoperatively on percentage total weight loss (%TWL) and comorbidities.

Results
A total of 40,640 patients underwent a gastric bypass procedure or sleeve gastrectomy between 2015 and 2018. Within this cohort, 709 patients (1.7%) suffered a major complication requiring reoperation within 30 days. %TWL at 24 months was 33.1 ± 9.2 in the overall population, versus 32.9 ± 8.7 in the patients who underwent a reoperation (p=0.813). Both analysis per year and Cox regression techniques revealed no differences in long-term follow-up regarding percentage TLW, and weight loss success rates (%TWL>20%) in patients who underwent a reoperation compared to patients without reoperation. At 5 years, the availability of follow-up data was low. No differences were observed in the remission of comorbidities.

Discussion
Major complications requiring reoperation within 30 days of gastric bypass surgery or sleeve gastrectomy did not affect long-term outcomes with regard to weight loss or remission of comorbidities.
