An Analysis of Publications on Climate Change Communication Using a Bibliometric Lens
Authors: Abdullah Khairul Hafezad
Published: October 2023

The effectiveness of climate change communication is incommunicado when there is a lack of comprehensive efforts to increase public knowledge and encourage proactive steps. The main objective of this study is to examine the evolving trends in publication and the developmental trajectory within climate change communication research, development, and publications. This study utilised datasets from the Scopus and Web of Science (WoS) databases, which were further analysed using the ScientoPy and VOSviewer. The findings suggest that there has been a notable increase in the number of publications since 2008, particularly in the WoS database, indicating a growing recognition and a more focused endeavour by researchers to delve into climate change communication. The most frequent keywords employed by past researchers were “Climate Change”, “Climate Change communication”, and “Climate communication”. The emergence of keywords such as “social media”, “science communication”, “environmental communication”, “framing”, and “climate action” in the year 2020 onwards signifies their recent prominence. Examining research growth and trends in climate change communication provides valuable insights into the advancements, recurring topics, and prominent individuals within this discipline. In a nutshell, the current study highlights the significance of proficient communication in tackling the intricate issues associated with climate change that can be a reference to potential readers and future researchers keen on this domain.

Published: October 2023

Grassland ecosystems, characterized by open landscapes dominated by grasses, encompass diverse formations influenced by geological, climatic, and anthropogenic factors. These environments play a pivotal role in global biodiversity, carbon cycling, and ecosystem services. Due to the worldwide loss and degradation of these habitats, grassland birds are experiencing an unprecedented population decline. This work aims to supply an in-depth exploration of the conservation status of Cerrado grassland birds, including their population trends, protective measures, and primary threats within this bird group. Through an exhaustive literature review, conference of endangered species databases, and field data of grassland birds gathered by us, we compiled a comprehensive dataset detailing the trends, threats, and distribution of Cerrado grassland birds. The Cerrado, the world's largest savanna and Brazil's second-largest biome, accommodates 116 bird species specialized in grassland formations, including 13 endemics. Significantly, a notable proportion (26%) of endangered bird species in the Cerrado are strongly associated with grasslands. The primary threats faced by this group encompass habitat loss and degradation, the proliferation of exotic grass species, and the recurrent incidence of wildfires. Upon analyzing population trends, a concerning 37% of Cerrado grassland birds show declining numbers, with inadequate representation in existing protected areas. While grasslands hold global significance, conservation endeavors often give precedence to tropical forests. The preservation of central Brazil's grassland formations assumes utmost importance in safeguarding the abundant biodiversity of the Cerrado. These formations function as pivotal habitats for endangered and declining bird species, underscoring the pressing need to develop conservation strategies attuned to the unique challenges posed by grassland environments.

Authors: Konyar Dilan , Foto Egemen , Zilifdar Foto Fatma , Buyukbingol Mehmet Erdem
Published: October 2023

Background:

As cancer stands as a significant global health concern, many heterocyclic
compounds that are more effective in cancer cells than healthy cells are being investigated for their selective
anticancer potentials. One such compound is fenretinide, a synthetic derivative of retinoic acid
that has a broad spectrum of cytotoxic activity against primary tumor cells, cell lines, and/or xenografts
of various cancers. In this context, bexarotene and its derivatives, synthesized from hybridization of the
fenretinide, are expected to possess a potential anticancer activity.

Objective:

The objective of the present study was to investigate the synthesis of novel amid-derived and
bexarotene-based compounds, as well as to assess their cytotoxic effects in different cancer cell lines.

Methods:

This study involved the synthesis of twelve novel retinoid derivatives (6-17) in a six-step
process. The cytotoxic activities of these compounds were assessed against various cancer cell lines,
such as A549 (human lung carcinoma), HeLa (human cervical cancer), MCF7 (human breast adenocarcinoma),
and WiDr (human colon adenocarcinoma). The chemical structures of these compounds were
elucidated through their elemental analysis, mass spectrometry (ESI+, ESI-), as well as 1H-NMR and
13C-NMR spectroscopic data.

Results:

The obtained cell toxicity results indicated that compounds 6, 8, 11, 12, 13, 14, and 17 were
found to exhibit the strongest cytotoxic activity in above mentioned cancer cell lines. The IC50 values
for active compounds, 11 and 12, were determined as 2.38μM and 2.29μM, respectively. Remarkably,
these compounds displayed higher cytotoxic activity in the WiDr cell line related to positive control,
camptothecin (CPT). Moreover, compounds 14 and 17 demonstrated very similar level of cytotoxic
activity to CPT, indicating their potential for antitumoral applications upon further studies.

Conclusion:

While compounds 11, 12, 14, and 17 indicated a very comparable anticancer activity to
CPT, compounds 6, 8, 11 and 12 showed more selective anticancer effect against cancer cells than noncancerous
cells. In accordance with the findings of the present study, they can be evaluated as primary
candidates for further studies, specifically as RXRα-targeted anticancer agents.
Evolutionary Stress Detection Framework through Machine Learning and
IoT (MLIoT-ESD)
Authors: Bansal Megha , Vyas Vaibhav
Published: October 2023

Background:

Life nowadays is full of stress due to lifestyle changes and the modernera race. Almost everyone around us is suffering from stress and anxiety. Mostly, stress identification is done by medical practitioners in a very late stage in which suitable help measures cannot
be provided and hence result in suicides or early age deaths due to cardiac arrest, etc. One major
reason behind the delay is the time required in stress identification by traditional approaches, and
above that, the amount of time and financial support expected is always not feasible to be available. Hence, in this paper, we proposed an evolutionary research framework for stress identification by the usage of both machine learning and IoT. Here, we also conducted a pilot study on 83
records available over the decade since 2014 using PRISMA guidelines, and a bibliographic network visualization was also performed using VOS viewer.

Objectives:

This study aimed to develop a stress detection framework using Machine Learning
and the Internet of Things (IoT) as technology advanced over a decade.

Methods:

More than 80 research papers from honorable repositories like Scopus and Web of Science were gathered according to the guidelines of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) 2020, and the VOSviewer tool was further applied to construct the bibliographic depictions. Various datasets and methods used over ten years with their
performance were also discussed.

Results:

This research was conducted to gather various types of stressors, the impact of various
Machine Learning and IoT algorithms and concepts on various datasets and their respective results.

Conclusion:

Various available datasets and results with multiple algorithms were discussed in a
crisp tabular form for better understanding. A methodology based on an amalgamation of Machine Learning and IoT was also proposed due to various research gaps available so that stress detection could be done in a cost-effective way.
Chitosan Biopolymer As Sustainable Material For Chromium Removal From Waste Water Bodies
Authors: Lal Seema , Bhatnagar Shilpi
Published: October 2023

Rapid industrialization by humans is a dominant source of waste materials
in water bodies and has created serious environmental problems, which has made the
survival of life forms on land as well as in water bodies a challenge. Water gets contaminated
by human waste, domestic sewage, wastewater discharges and effluents
from industrial sites such as factories, refineries, and mines, accidental spills of chemicals,
agricultural run-off, toxic metals and radioactive materials. The toxic nonbiodegradable
chemicals in industrial waste are treated by various methods such as
adsorption, coagulation, ozonation, membrane filtration, ion exchange, chemical oxidation
and biological treatments. Biopolymers such as cellulose, chitosan, alginate and
keratin proteins are the most sustainable, renewable and biocompatible polymers
commonly used for wastewater purification. Chromium VI is one of the serious aquatic
pollutants released as effluent from various industries and is considered a potentially
toxic metal ion for humans and aquatic life. In the past decades, various conventional
methods with their own merits and demerits have been explored for Cr decontamination
from wastewater bodies. The present study highlights the application of
Chitosan biopolymer as an effective and sustainable material for efficiently removing
Cr VI metal ions from wastewater bodies.
Introduction and Summary
Authors: Rufer Alfred
Published: October 2023

The motivation for the use of compressed air as an energy carrier and as a
storage means for many industrial applications resides in the simplicity and low-cost
conditions of its implementation. However, conventional pneumatic technology suffers
from a very low energetic efficiency even if the production, use and recycling of the
components can be said to be environmentally friendly, and it does not use problematic
materials. This introductory chapter positions pneumatic technology and discusses a
possible extension of the applications to the sector of energy storage in a general
manner. The chapter gives the historical background of the presented developments of
the book and gives an overview of the content of the document.
Coupling Two Rotary-Type Actuators
Authors: Rufer Alfred
Published: October 2023

This chapter presents the first example of the combination of two actuators
of different volumes with which the principle of adding an expansion work can be
realized. The two semi-rotary actuators are mechanically coupled and describe an
oscillatory motion. Then the oscillatory motion is transmitted to an electric generator
through a so-called motion rectifier. The structure of the new system is presented with
the control valves and control circuitry. The different variables of the system as
pressure, torques, and mechanical work are calculated by simulation. The efficiency of
the new system is calculated and compared with the efficiency of a single actuator
without expansion. The principle of adding an expansion work with semi-rotary
actuators is then presented but with one actuator only where the expansion occurs in
the same and unique chamber. Efficiency, torque waveform and produced mechanical
work are presented, as well the control circuits.
The power reversibility of a system using semi-rotary actuators is addressed, and a
solution with a crankshaft is studied.
Conclusion
Authors: Rufer Alfred
Published: October 2023

The chapter serves as a conclusion to the different principles, systems and
application examples described in this book.
From the original air-powered diving lamp driven by a semi-rotary pneumatic actuator
to the final example of the gas booster, different systems have been proposed with a
large benefit in terms of energetic efficiency or in other terms, in the reduced amount
of air consumed.
Nanoparticles in Environmental Pollution Remediation of Xenobiotics
Authors: Morteza Naghib Seyed , Garshasbi Hamid Reza
Published: October 2023

Environmental deterioration is currently a major problem for both emerging
and wealthy nations. Extensive industrialization and intensive agricultural activity are
the main causes of land, water, and air contamination. There are numerous
conventional treatments for various environmental contaminants, but each has
drawbacks. As a result, a different approach is necessary, one that is efficient, less
harmful, and produces better results. In terms of cleaning up the environment,
nanomaterials have garnered much interest. Nanomaterials outperform more traditional
methods for environmental remediation due to their enormous surface area and strong
reactivity. For particular applications, they can be altered to include new
functionalities. Nanoscale materials can be very reactive due to the high surface-area to-volume ratio and a greater number of reactive sites. These traits enable greater
contaminant interaction, which prompts a rapid decrease in pollutant concentration. In
order to remove toxins from diverse environmental media (e.g., soil, water, and air),
environmental remediation primarily uses various methods.

A revisited and general Kane’s formulation applied to very flexible multibody spacecraft
Authors: Madonna D.P.
Published: October 2023

Abstract. Current space missions require predicting the spacecraft dynamics with considerable reliability. Among the various components of a spacecraft, subsystems like payload, structures, and power depend heavily on the dynamic behavior of the satellite during its operational life. Therefore, to ensure that the results obtained through numerical simulations correspond to the actual behavior, an accurate dynamical model must be developed. In this context, an implementation of Kane’s method is presented to derive the dynamical equations of a spacecraft composed of both rigid and flexible bodies connected via joints in tree topology. Starting from the kinematics of two generic interconnected bodies, a systematic approach is derived and the recursive structure of the equations is investigated. The Kane’s formulation allows a relatively simple derivation of the equation of motion while obtaining the minimum set of differential equations, which implies lower computational time. On the other hand, this formulation excludes reaction forces and torques from the dynamical equations. Nevertheless, in this work a strategy to compute them a posteriori without further numerical integrations is presented. Flexibility is introduced through the standard modal decomposition technique, so that modal shapes obtained by FEA software can be directly utilized to characterize the elastic motion of the flexible bodies. A spacecraft composed of a rigid bus and several flexible appendages is modeled and numerical simulations point out that this systematic method is very effective for this illustrative example.

O ensino artístico e especializado da música em Portugal no século XX e a evolução histórica da disciplina de formação musical
Authors: Carneiro Hermano
Published: October 2023

A atividade musical de caráter pedagógico realizada em Portugal, durante o século XX, é disposta em diferentes fases de desenvolvimento a que Vasconcelos (2010) trata por: educação da sensibilidade (1901–1919); influência europeia (1919–1930); ensino técnico (1930–1971); experiência pedagógica (1971–1983) e inserção e expansão (1983–2000). O presente artigo procura expor os principais elementos caraterizadores dessas fases de desenvolvimento, destacando as disciplinas que precederam a, ainda hoje denominada disciplina de Formação Musical, ministrada nos cursos artísticos especializados de música (Carneiro, 2022). A partir de diplomas legislativos e de diversas referências bibliográficas publicadas foi possível compreender os principais aspetos que, ao longo do século XX, marcaram o pensamento pedagógico vigente em Portugal, assim como a influência que se fez sentir nas práticas musicais de natureza pedagógica desenvolvidas nas disciplinas que precederam a já referida disciplina de Formação Musical.

Uma cartografia da divulgação científica em Ciências da Linguagem no Brasil e em Portugal
Authors: Cristóvão Vera Lúcia Lopes , Ferreira Laura Márcia Luiza , Cardoso Inês , Pereira Luísa Álvares , Ambrósio Susana
Published: October 2023

Neste artigo, pretendemos  mapear  mídias de produções multimodais de Divulgação Científica (DC) nas Ciências da Linguagem, no Brasil e em Portugal, de 2018 a 2022. Procuramos ainda compreender as motivações e modos de ação de linguistas que se dedicam a esta atividade. Para tal, usamos a técnica snowball para o primeiro objetivo, e entrevista semiestruturada para o segundo. O mapeamento mostra que  a  DC está em crescimento no  Brasil, particularmente nas mídias digitais multimodais, tais como podcasts, vídeos do YouTube e blogues,  em sua maioria, programas não institucionais que podem promover mais liberdade na escolha temática, nomeadamente em produções multimodais  com menção direta a fatos do cotidiano ou do contexto. Em Portugal, a atividade encontra-se em emergência, com predominância do modo escrito, como artigo de opinião em jornal nacional, e algumas iniciativas institucionais de caráter multimodal por parte de um centro de investigação. Segundo os nossos entrevistados, os modos de ação da DC desenvolvem saberes e competências relacionados à comunicação não só fora da academia, como também dentro (para pares e para alunos), o que seria mais uma razão pela qual mais linguistas deveriam empreender este tipo de ação de DC, considerada importante em prol da (in)formação cidadã.
Rising Incidence of Post-Electoral Dispute in Nigeria: Implications for its Democracy
Authors: Ifejika Solomon
Published: October 2023

Since Nigeria’s return to democratic rule in 1999, the country has continued to witness high rates of election petitions filed at election petitions tribunals across the country after each election period, in a bid to resolve electoral disputes. All the elections the country has conducted - 2003, 2011, 2015 as well as the most recent 2019 general elections, have produced large numbers of post-election petitions. In the opinion of this study, the major factor responsible for this unfavorable situation is the weakness of the country’s electoral process and institutions, which persistently paves the way for massive irregularities that render elections results incredible and unacceptable, thereby leading to disputes and filing of petitions at tribunals by aggrieved candidates and their political parties. The study argues that the prevailing high incidence of election petitions being witnessed in Nigeria in the Fourth Republic is unwholesome and inimical to the country’s democratic practice. In view of this, the study emphasizes that Nigeria needs to take urgent necessary measures to address the situation. Accordingly, the study suggests that Nigeria should strengthen her electoral process and institutions to attain highly credible, transparent, free and fair and acceptable elections in future times. This, in the views of the study, will help to reduce the spate of elections-related petitions to the barest minimum and avert the negative effects of the phenomenon on the country’s democracy. The study adopts the documentary methods of data collection and data analysis which enabled adequate achievement of the objective of the study.
On the Phenomenology of War and Peace: Studying the Ukrainian "Event"
Authors: Özigci Yunus Emre
Published: October 2023

The current studies of the event and the phenomenon of the war (and of the peace) reflect the ontological and –ensuing- temporal problems of the IR theorising, stemming from the IR field’s purely intersubjective nature, from its lack of the anchor of self-standing objectivity in contrast to the positive and social sciences. As such, the theory-based studies in the field become genetic processes, altering the immediate, pre-theoretical, intersubjective givenness of the IR phenomena and events within their narratives, in accordance to their preceding constructs. Yet, the phenomenology, with the intervention of the phenomenological ontology where it relapses itself into theorising, offers notions and tools for a pre-theoretical access to and description of the intersubjective immediacy of them. In order to outline such a study,  this paper examines the event of the Ukrainian War and through it, the phenomena of the war and the peace. It attempts to describe its pre-theoretical, intersubjective immediacy in its synthetic unity in ontological and temporal terms. This attempt brings forth a descriptive and temporally progressive ground of givenness composed of the referentiality to the interstate intersubjectivity, to the “given” interactional forms of the involved actors, which form the synthetic unity of the event (the Ukrainian War and preceding/ upcoming state of Peace) and of the related phenomena (war and peace).
Psychological Problems of Polish Organizations in Transition
Authors: Kożusznik Barbara
Published: October 2023

The purpose of this paper is identification of psychological problems, diagnosis of workers´ ideas and initiatives aimed at solving those problems, and diagnosis of readiness of workers to change. There is an assumption that organizational behaviour is multilevel, involves multiple variables, and requires multivariate measurement. In this paper I ask questions about the level of different psychosocial and emotional dimensions, the main problems experienced by organization members, and the greatest barriers in the process of change. I also examine what should be done to solve existing problems.
I constructed and used the Organizational Assessment Questionnaire (OAQ) that is composed of 15 sections and 190 questions covering different sectors of organizational functioning. The OAQ was completed by 432 workers from organizations in the highly industrialised Upper Silesia region of Poland.
On the basis of OAQ, interviews and discussions with employees I divided the results into positive and negative factors. Positive factors are those that can be treated as opportunities; employees’ emotional engagement and self-perceptions of competence and ambition. Negative factors were psychological barriers in the process of organizational transition; functioning in area of HRM that badly need to be changed. In conclusion I proposed some solutions in the area of Human Resources, management trust and workers’ self- assessment.
A tenuous link: Psychological contracts and perspective-taking between a promotion agency and its workers
Authors: Calvard Thomas S. , Carter Angela J. , Axtell Carolyn M.
Published: October 2023

This paper explores the relationships between employees‟ psychological contract perceptions, perspective-taking between employees and employers, and employees‟ responses to declining job satisfaction (e.g., absenteeism). Fifteen employees of a promotion agency participated in semi-structured telephone interviews, and their comments were explored qualitatively using template analysis. Employees‟ work behaviour was related to their perceptions of employers‟ psychological contract violation and the perspective-taking attempted by both parties. Implications for employment relationships and contingent workers are discussed.
The impact of prior experience of an almost accident on comparative optimism
Authors: Spitzenstetter Florence , Raffin Didier
Published: October 2023

The first aim of this study was to examine comparative optimism (the difference between evaluation of one‟s own risk and the evaluation of other people‟s risk). Because research supports the notion that personal experience moderates the optimistic bias, the second aim of the present study was to test the impact of prior experience of an “almost accident”. Real accidents are fortunately not too frequent, thus we wondered if the confrontation with an almost accident; which is a more frequent situation, could have the same impact on risk evaluation. Employees of a metallurgical plant in the Eastern part of France who have been confronted or not with an almost accident were asked to evaluate to what extent a work accident was likely to occur for them and/or one of their work colleagues. We found that people more usually consider the risk of their colleague being a victim of a work accident than themselves. However, we found for employees who have had an almost accident in the last three months this phenomenon is opposite. They estimate that their own risk as higher than the risk to their colleague.
Activation of the “What is beautiful is good” stereotype during job candidate selection: What is the role of the recruiter’s own characteristics?
Authors: Medisauskaite Asta , Kamau Caroline , Endriulaitiene Aukse
Published: October 2023

When a recruiter is assessing a large number of job candidates, the stereotype “What is beautiful is good” can be used as a cognitive shortcut towards a quick decision. Previous literature has not explained the role of individual differences among recruiters. This article is drawing a possible connection between activation of the stereotype “What is beautiful is good” and recruiters' ideological attitudes, personality, their own physical attractiveness, and their socio-demographic characteristics. Understanding these relations could help to improve selection processes by reducing bias in hiring decisions based on stereotypical thinking. Recruitment staff should be trained about social cognition and Human Resource (HR) departments should establish protocols and policies that anonymise job applicants. HR departments should commission psychometric testing to evaluate personality/ideological attitudes of potential would-be recruitment staff and gain advice about the implications of staff test scores.
The Amsterdam Effect – Report from EAWOP’s 2nd WorkLab, 2013
Authors: Duignan Kieran
Published: October 2023

Sixteen participants attended the 2nd European Association of Work and Organizational Psychology WorkLab in Amsterdam, on the northern coast of the Netherlands, from 14-16 November, 2013. Participants were offered a structure with flexible boundaries for making sense of the practical elements of the WorkLab theme; Leadership and Conflict. Three speakers addressed issues around the tasks, processes and relationships of leadership, conflict and imbalances of power which they addressed in terms of these themes: social processes of conflict and of mediation interventions; emotional self-regulation and influencing as a leadership accomplishment; and conflicts emerging from insufficiently controlled ‘dark’ facets of personalities of some leaders. In sum, this was a great opportunity for psychologists to consider ways to reconfigure and recalibrate interventions about leadership and conflict at work.

El aumento de infecciones comunitarias como las hospitalarias a causa de infecciones por bacterias con resistencia a múltiples drogas antibióticas. Constituyen en la actualidad como uno de los problemas de mayor preocupación en salud pública global, generando la necesidad de poder encontrar nuevas alternativas terapéuticas, siendo así que se ha ampliado la búsqueda a través de los principios activos en plantas con efecto antimicrobiano. Maytenus macrocarpa ̈Chuchuhuasi ̈ es un árbol nativo de la región Amazónica del Perú utilizado como analgésico, antiinflamatorio y antioxidante. Este árbol se caracteriza por contener compuestos activos como triterpenoquinonas y dímeros triterpénicos los cuales pueden presentar actividad antimicrobiana. El objetivo del presente estudio fue determinar la acción antimicrobiana de flavonoides y alcaloides de Maytenus macrocarpa, contra las cepas de Pseudomonas aeruginosa ATCC 25923 y Escherichia coli ATCC 25922, determinándose la actividad antimicrobiana de los extractos mediante el método Kirby Bauer. Se encontró que las cepas de Pseudomonas aeruginosa ATCC 25923 y Escherichia coli ATCC 25922 fueron resistentes a todos los extractos de Maytenus macrocarpa, siendo sensible la cepa de Staphylococcus aureus ATCC 25923. Se concluye que los extractos de Maytenus macrocarpa no presentan actividad antimicrobiana frente a cepas gram negativas, pudiendo ser considerada una buena opción terapéutica frente a cepas gram positivas.

Histological changes and diagnostic value of immunoglobulin G/M to Helicobacter pylori in gastric cancer patients
Authors: Nassir Faisal Ahmed , Madhi Raed , Algaber Anwar
Published: October 2023

Stomach cancer is believed to be one of the most common cancers that lead to death. In Iraq, stomach cancer occupies the seventh place of cancer occurrence in both sexes and is counted as one of the ten most common cancers.

The current study is designed to explore the link between Helicobacter pylori (H.pylori) infection and the development of incidences of stomach cancer. In addition, related age and gender were also studied. Histological examinations of stomach biopsies were performed in suspected people to evaluate stomach cancer occurrences. Of the 40 patients with stomach cancer, the infection of H. pylori was emphasized in 34 (66.66%) with serum IgG/IgM, which reflected a significant frequency for infection of H. pylori in stomach cancer patients. The study also showed that males with H. pylori infection record a higher percentage than female patients with stomach cancer. Moreover, the results revealed that age is also connected to H. pylori infection. Based on the above findings, monitoring infected people with H. pylori might be an excellent strategy to control stomach cancer occurrences.

An Empirical Research on the Reasonable Limits of Teacher Discipline in Primary and Secondary School in China - Focusing on Corporal Punishment
Authors: Zhang Xinyi
Published: October 2023

With the promulgation of the Rules on Educational Discipline for Primary and Secondary School Teachers (for Trial Implementation), China has initially established a four-tier educational disciplinary system. The disciplinary power is a natural and legitimate power of teachers, and discipline is a necessary means and statutory function for teachers to carry out their educational management duties, while the current operation of the disciplinary power in China shows a trend of polarisation. Corporal punishment, an important part of Chinese traditional education system, is still used by teachers today, but there is a lack of written regulations to define its form and judge its reasonableness. In order to achieve a rational return to corporal punishment and discipline, it is necessary to further refine the relevant legal policies and build a better educational disciplinary system, as well as to strengthen the guidance of ideas and public opinion, so as to build a favourable social environment for teachers to implement corporal punishment and discipline within reasonable limits.
How Can Home-School Cooperation Promote Ideological and Political Education for Secondary Vocational School Students
Authors: Peng Hua , Zhang Penghao
Published: October 2023

The ideological and political education of secondary vocational school students is of utmost importance, requiring not only scientific guidance from schools but also the active involvement of families. Currently, there are common issues in the process of school-home cooperation in secondary vocational schools, such as parents not prioritizing students’ learning, limited and superficial forms of cooperation, and communication barriers between families and schools. By analyzing the significance of school-home cooperation in the ideological and political education of secondary vocational school students, this paper provides strategic suggestions for implementing school-home cooperation in secondary vocational schools. These suggestions include promoting the correct concept of school-home cooperation, enhancing the guiding ability of family education, and establishing multiple channels for school-home cooperation. Through these efforts, a synergistic educational force can be formed to promote collaborative education between families and schools.
