Inquiry and Uncertainty of Thinking: Education with Technology
Authors: Daher Wajeeh
Published: July 2024

Abstract: This paper develops an argument regarding thinking, inquiry, uncertainty and subject in working with technology. This development serves the analysis of learning with technology and discusses the educational consequences of working with technology. Doing that, the paper discusses the influence of two main features of technological cognitive tools on the learner’s inquiry: interactivity and dynamicity. It argues that interactivity and dynamicity of the technological cognitive tools support the learner in his or her interaction processes during inquiry to investigate uncertain situations. It also argues that technological cognitive tools can support the imagination processes of learners that facilitate the development of their knowledge about the subject matter, besides facilitating their problem-solving processes. These tools can enrich the interactions between the learners during their engagement with the subject matter. It is argued that technological cognitive tools can support the subject in dealing with the uncertainty in learning and thus enriches her or his experimenting identity. This support could be strengthened by taking care of the tool’s design.
Feminist Ethics in Universities: How to Make Timely Decisions that Represent Community Values
Authors: Kumar Rahul , Forsythe Giulia
Published: July 2024

Abstract: In practical terms, decisions on various academic matters in universities are complex and reflective of the views held by those in positions of power. For a more egalitarian view derived from a feminist perspective, this paper proposes an alternative form of decision-making. An underlying moral code and its corresponding decisions influence policies and the broad spectrum of educational futures in universities. According to Walker (2007), theoretical-juridical models, which have dominated ethical understandings, assume a prevailing moral code that embodies universal ethical principles and applies to all people in every jurisdiction at all times. By contrast, embodied perspectives that recognize the relationality of networked participation enliven Walker’s expressive-collaborative model (ECM) through moral conversations and negotiations among moral agents who are members of that specific community. The authors cite the #femedtech networked participatory community as an embodiment of feminist values that the ECM proposes and describe #femedtech’s value activity and code of conduct generation activity. This paper applies feminist ethics to ameliorate universities’ policy-making process. The paper builds the case for university community values to guide university decisions and advocates strategic trust as an essential criterion to uphold communal values. Finally, the paper concludes with practical propositions that reflect a commitment to democratic, deliberated, and inspiring process-based decision-making responsive to a diverse community’s moral lives and ethical needs.
Sacred Ground: Higher Education and the Importance of Place
Authors: Aper Jeffery P.
Published: July 2024

Abstract: The growing emphasis on cyberspace as a primary locus for the teaching and learning efforts of modern colleges and universities belies larger issues of connection, meaning making, and community necessary to human growth and well-being. College and university campuses can be critical loci of such functions if they are understood as sacred places devoted to ideals of growth, development, community, communication, and especially of freedom of inquiry, expression, and conscience. Though the current pandemic has reinforced reliance on online methods of instruction and interaction, the critical longer term needs of individuals and society at large are served by a renewal of the commitment to college and university campuses as places dedicated to the essential ideals of respectful polity, comity, and mutuality.

Financial Crises and Financial Contagion in Japan
Authors: Ovcharov A. O.
Published: July 2024

The article analyzes the features of the financial crises in Japan in the context of using theoretical and practical approaches to financial contagion. A brief overview is made with the identification of the causes, nature, and consequences in relation to the three significant financial crises observed in the period 1990– 2009. A strong impact on the Japanese economy was exerted by the banking crisis of 1997–2001, which became one of the most noticeable events of the “lost decade.” Its lessons allowed the Japanese government to overcome the global financial crisis of 2007–2009 with minimal losses, which negatively affected not so much the credit and stock markets as the real sector of the Japanese economy and its foreign trade.

 From a scientific standpoint, the spread of crises is productively considered from the standpoint of the theory and methodology of financial contagion. It is a process of transmission of negative shocks that can lead to the disruption of fundamental links between countries and markets, thereby contributing to the growth of crises and instability. The article shows that Japan can act as both a transmitter and a recipient of infection. Examples of studies that examine the channels and direction of financial contagion in Japan are given. An important feature has been identified, which is that the main channel for the transmission of shocks in a given country is trade relations, and not financial ones. Taking this circumstance into account explains the effectiveness of the policy of supporting the real sector of the economy pursued by the Japanese government during the global financial crisis of 2007–2009.

In order to illustrate the methodology of financial contagion, the article conducted an empirical study of the country and cross-industry effects of infection in the Japanese economy during the COVID-19 period. A specific infection detection tool (statistical tests) and an extensive empirical base were used. As a result, the country effects were confirmed only partially – Japan was the recipient of the financial contagion that came from China, but weakly transferred it to other countries. Cross-industry infection spread more actively (it was recorded by more than half of the tests). At the same time, uneven transmission of shocks between sectors was detected; possible causes of high or low susceptibility to infection in different sectors were discussed.

Cultivating a Lifelong Commitment to Social Justice: A Quantitative Analysis
Authors: Lansing Sean T.
Published: July 2024

Leaders with a personal and professional commitment to social justice are necessary to meet the demands of the complex systems and structures that perpetuate marginalization and oppression. The purpose of this study was to better understand common experiences people perceived as influential on their commitment to social justice. The study was designed to quantitatively measure the perceived influence of five variables determined by qualitative research on the development of a social justice orientation. These variables were the influence of significant persons, exposure to injustice, education/learning, work experience, and religion/spirituality. The study found that all five variables are considered influential to personal and professional commitment to social justice using multiple statistical analyses. Other findings include race, level of education, age, and involvement in a religious tradition impacting the perception of influence of different variables as well as working with marginalized populations or experiencing marginalization. These findings have several implications for cultivating commitment to social justice across various disciplines. This article explores implications of these findings for the Catholic community of faith, with a view to generating high impact formation experiences that will foster lifelong commitment to social justice as an expression of Catholic faith.
Distortions of Normativity in the Church’s Sexual Abuse Scandal: The Role of Moral Theology
Authors: Prusak Bernard G.
Published: July 2024

This essay considers how distortions of normativity figured in the church’s sexual abuse scandal. The focus falls in particular on how the social articulation of morality may go awry and on the ways this happened in the church. The essay reviews work by psychologist Marie Keenan, philosophers Herlinde Pauer-Studer and J. David Velleman, and theologian Norbert J. Rigali, SJ. Rigali draws attention to the role of traditional moral theology in shaping the moral perception of clergy. According to him, “The content, structure, and method of [this] sin-centered discipline…shaped the way in which the Christian moral life was understood in the Church.” His primary evidence for that thesis is the way the sexual abuse of children was perceived by clergy, in particular bishops, prior to 2002. As a rule, the victims fell out of the picture. Against that background, the essay submits that the roots of the scandal lie not in moral relativism, but in a moral blindness induced, ironically, by a distorted view of the moral life.

Authors: Glavač Timotej ,   Faculty of Arts, University of Ljubljana, Ljubljana, Slovenia, Puklek Levpušček Melita ,   Faculty of Arts, University of Ljubljana, Ljubljana, Slovenia
Published: July 2024

This study examined the link between perceived romantic relationship (RR) importance (relationship desire and dismissal) and emerging adults' romantic experiences, including relationship status, number of partnerships, and relationship durations. It also explored how individuation from parents contributes to the prediction of these experiences. Participants (N = 464, 64.4% female, Mage = 22.59) reported on their romantic relationship importance, relationship experiences, and perceived connectedness and intrusiveness from parents. Hierarchical regression analyses revealed that perceived RR importance significantly contributed to the prediction of romantic experiences beyond demographic factors. Additionally, paternal intrusiveness negatively predicted the duration of current and longest relationships. The findings suggest that RR importance and individuation, especially in relation to the father, play an important role in emerging adults' romantic experiences.

Authors: Pološki Vokić Nina ,   Faculty of Economics & Business, University of Zagreb, Zagreb, Croatia, Klindžić Maja ,   Faculty of Economics & Business, University of Zagreb, Zagreb, Croatia
Published: July 2024

People's happiness has become a first-class political question, which urges both governments and organisations to create policies and practices aimed at improving people's happiness, one of which includes human resource management (HRM) practices. As studies exploring the association between country level HRM practices and national happiness on the academic level are scarce, especially empirical ones, the aim of this paper is exactly to address this gap. HRM data used in the study were collected through the Cranet 2014-2016 survey round and refer to 5,093 organisations operating in 27 countries on five continents. National happiness data, Cantril ladder indicator (CLI) as a measure, and six correlates of national happiness, were obtained from the World Happiness Report database. Findings suggest that HRM practices associated with the highest levels of national happiness include: using information technology (IT) recruitment platforms, recruiting based on potentials and not on present knowledge/skills, customised compensations, various work-life balance initiatives, and training and development primarily for career's and not employer's sake, which corresponds with younger workforce cohorts' preferences.

The role of climate change conspiracy in consumers’ pro-environmental behaviors
Authors: Thieme Jeff , Stafford Marla Royne , Coleman Joshua
Published: July 2024

Objective of the study: This study seeks to investigate psychological processes driving consumers to engage in home energy efficiency investment behaviors and the potentially inhibiting role climate change conspiracy beliefs play in those processes.
Methodology/approach: Our conceptual model offers a set of hypotheses that we test through structural equation modeling.
Main results: Our model offers strong support for the values-beliefs-norms (VBN) model and the inhibiting role of climate change conspiracy beliefs in consumer energy investment behaviors.
Theoretical/methodological contributions: Our research utilizes value-belief-norm (VBN) theory to test our hypotheses. Additionally, we utilized conspiracy theory and specifically, conspiracy ideation, to demonstrate the role conspiracy beliefs play in decisions to engage in energy investment behaviors.
Relevance/originality: Conspiracy theory and climate change are two important topics affecting society. This is the first research that investigates both of these topics within the framework of VBN theory.  Hence, our results have significant theoretical, management and social implications.
Management or social implications: Results suggest that those investigating decisions to adopt environmental products or engage in pro-environmental behaviors should consider the inhibiting role of conspiracies and using the VBN model as a key foundation.  Moreover, these results indicate that how managers promote pro-environmental behaviors to customers and society must consider conspiracy ideation in developing their marketing strategies.

Pesticide Induced Oxidative Stress on Non-Target Organism Labeo rohita
Authors: Pesala Ravi Sekhar , Yerragudi Savithri
Published: July 2024

The application of pesticides in agricultural activities can result in their runoff into water bodies, causing water contamination. This contamination poses a threat to water quality, rendering it harmful to aquatic organisms. This study investigated the acute toxic effects of the synthetic pyrethroid pesticide cypermethrin and the organophosphate pesticide chlorpyrifos, both individually and in combination, on the antioxidant enzyme activities viz., Xanthine oxidase (XOD), Superoxide dismutase (SOD) and Catalase (CAT) in the liver and gill tissues of the fish, Labeo rohita.  L. rohita were exposed to sub-lethal concentrations of cypermethrin and chlorpyrifos individually and in combination for 7 days. The concentrations used were 1/10th of the LC50 dosage for individual treatments (0.308 µg/L for cypermethrin and 44.28 µg/L for chlorpyrifos) and 1/20th of the LC50 for the combined treatment (0.154µg/L for cypermethrin + 22.14µg/L for chlorpyrifos). The findings of this study revealed a significant (P<0.05) increase in the activities of Xanthine oxidase (XOD), Superoxide dismutase (SOD) and Catalase (CAT) in both liver and gill tissues compared to the control group. The observed alterations were more pronounced in the combined treatment as compared to individual exposures, suggesting a potential synergistic effect of cypermethrin and chlorpyrifos.

Authors: Lasushe Khrote-U , Singh Prem Prakash , Chaudhary Kanhaiya Lal , Choudhury Hiranjit , Upadhaya Krishna
Published: July 2024

Diversity, biomass and carbon (C) stock (above- and below-ground) of woody species (>5cm dbh) were studied in 15 Community Reserves (CRs) of Meghalaya, Northeast India. A total of 287 species belonging to 72 families and 165 genera were enumerated from 7.5 ha sampled area. The number of individuals ranged from 888 to 1582 ha-1 with a mean density of 1182.4±57.76 individuals ha-1. The basal area ranged from 22.27 to 59.22 m2 ha-1 with a mean value of 41.60±3.23 m2 ha-1 in the studied sites. The total biomass and C stock ranged from 147.57 to 343.25 Mg ha-1 and 69.95 to 162.7 Mg C ha-1, respectively. The contribution of AGB and BGB to the total biomass and C stock was 79-82% and 18-21%, respectively. The variation in species richness, density, basal area, biomass, and carbon stock observed in the studied CRs can be attributed to their past land use and management history. The present study highlights that these CRs possess a high potential to act as carbon sinks, indicating that creating more CRs in the state could prove highly beneficial. Such an approach would not only help to preserve the region’s rich biodiversity but also aid in sequester the atmospheric carbon dioxide.

During Gangasagar festival, another lot of pilgrims come over with an intention to take a holy dip at the Gangotri conﬂuence. This mass gathering elevates the pollution levels. It depicts a cyclic usage of water having religious prototype, consisting of bathing at particular sites resulting in drastic alteration of the biogeochemical symmetry of the aquatic ecosystem. Phytoplankton being the primary producers occupies the base level of aquatic food webs. They have a potent role in indicating water quality. Even minute alterations in phytoplankton community can affect the world climate. Therefore, for maintaining a balanced ecosystem, their respective levels should be kept on a count. Phytoplankton biomass was maximum during post-Gangasagar phase and minimum during pre-Gangasagar. In terms of abundance, Bacillariophyceae exhibited prominence and Dinoflagellates diversified after Gangasagar festival implying high pollution levels of Sagar. The largest influence on phytoplankton plethora is nutrient scarcity. Also, blooms of dinoflagellates due to nutrient variability have large ecosystem impacts on water quality. These changes in the primary producers eventually affect primary production and biogeochemical cycle.

A field experiment using 5 treatments viz., T1 -Dark blue polythene mulch, T2 - Light blue polythene mulch, T3-Black polythene mulch, T4 -Paddy straw mulch and T5 – control was conducted to investigate the impact of various types of mulch material on growth, yield, and quality of Summer Squash (Cucurbita pepo L.) Cv. Pusa Alankar under the valley conditions of Srinagar Garhwal. The experiment was laid out in a randomised complete block design with five replications. The effect of mulching materials on almost all the growth, yield, and quality parameters under study was found to be statistically significant. The results revealed that the treatment T2 had maximum plant height (81.33 cm) and plant spread (61.12 cm) at harvest. It also showed the maximum collar diameter (1.92 cm) and the minimum days taken for the appearance of the first female flower (30.29 days). Moreover, it exhibited a higher fruit setting percentage of 78.52%, the minimum days taken to the first fruit harvesting (41.28 days) and the maximum number of fruits per plant (7.38), average fruit length (25.26 cm), and yield per plant (3.46 kg). In contrast, the treatment T4 resulted in the maximum plant height at 15 DAT (21.21 cm), average fruit weight (484 g) and fruit diameter (4.68 cm). On the other hand, treatment T1 demonstrated significant effects in terms of plant height at 45 DAT (46.73 cm), plant spread at 30 DAT (32.08 cm), and the number of harvestings (5.05). The experimental findings were diverse, with each treatment showing its influence on different parameters. However, considering the results, the treatment T2 - Light blue polythene mulch appears to be the most suitable option for enhancing the production of summer squash under the valley conditions of Srinagar Garhwal.

En los últimos años, ocurrieron diversos accidentes en presas en Brasil con daños ambientales significativos, lo que motivó una actualización de la Ley N.º 12.334 de 2010, conocida como “Ley Brasileña de Seguridad de Presas”, en 2020. Considerando este escenario y con el objetivo de difundir este tema, se realizó un levantamiento bibliográfico, indicando la legislación vigente integrada a un breve histórico nacional, apuntando sus instrumentos, enfocada en la clasificación de riesgos y daños potenciales asociados, así como en la estructura de gestión de la seguridad brasileña. Del mismo modo, se discutió el Sistema Integrado de Seguridad de Presas, concepto considerado el más completo para el control de presas. A través de esta investigación se pudo identificar que, a pesar de los grandes avances en el área, tanto en las teorías como en las legislaturas, existen varios aspectos y criterios que necesitan ser analizados y comprobados en la práctica. Cabe resaltar que la mejora continua de las capacidades institucionales públicas y privadas es uno de los aspectos fundamentales en cuanto a la seguridad de estas estructuras, como mejoras en el proceso de gestión de riesgos y avances en la predicción y evaluación del comportamiento de las presas.

The environmental culture in students and teachers of primary school educational institutions in the municipality of Santa Marta, Magdalena, Colombia was characterized. The study presents a descriptive analytical field approach, with a non-experimental design. The population was made up of 450 students and 15 teachers, from three primary educational institutions in the municipality of Santa Marta, Magdalena, Northern Colombia. Likewise, to collect the information, a questionnaire was used aimed at the students with two dichotomous response alternatives (yes-no), and another with scale-type multiple alternative responses. Teachers do not always lead the student to carry out research regarding the environment; the strategies applied are sometimes planned without taking into account the importance of generating environmental values in the student and a positive change in environmental behavior. Strategies must be established in the classroom that force students to carry out research processes in each of the tasks assigned by the teacher.

El propósito de esta investigación fue la de avanzar en la caracterización del pensamiento matemático estructural en estudiantes de educación básica secundaria en el contexto de la resolución de problemas retadores de la teoría de números, se diseñaron, aplicaron, rediseñaron y nuevamente se aplicaron dos sistemas de actividades que involucraron: el juego del SET y la aritmética congruencial. Se concluye con una teoría local en donde se especifican los elementos de la teoría categorial, descriptiva, explicativa y prescriptiva. La aplicación de la ingeniería didáctica como metodología de la investigación y diseño, la estrategia de resolución de problemas por indagación y las orientaciones del maestro lograron desarrollar en el estudiante el pensamiento matemático estructural, el cual se evidencia al alcanzar al menos una de las cuatro categorías: Hallar conexiones y patrones; reconocer relaciones; entender propiedades; generalizar y razonar. Este marco emergente es el resultado de la reorganización de los aportes de investigadores como (Mason; Johnston, 2004), (Mulligan; Mitchelmore, 2009), (Harel; Soto, 2017) y (Gronow, 2021) adaptado a las necesidades del entorno.

Uma das temáticas investigadas por (Bandura, 1986) na teoria social cognitiva é o desengajamento moral, que são mecanismos que, os indivíduos usam para justificar o pensamento e o comportamento para praticar atos antissociais, sem se sentirem culpadas ou censuradas por isso. São oito os processos postulados por (Bandura, 1986) para explicar as ações imorais que os indivíduos realizam: Justificativa moral, comparação vantajosa, linguagem eufemística, minimização, ignorância ou distorção das consequências, desumanização, atribuição de culpa, deslocamento de responsabilidade e difusão de responsabilidade. Há uma escassez de estudos sobre o desengajamento moral no Brasil, portanto o presente trabalho pretende responder ao seguinte problema de pesquisa: Quais os processos de desengajamento moral postulados por Bandura estão presentes no Filme “Quanto Vale ou É Por Quilo” O objetivo do estudo foi fazer uma análise do filme “Quanto vale ou é por Quilo “segundo a abordagem do desengajamento moral de Bandura. A análise demonstrou que os personagens do filme recorrem a estratégias de desengajamento para justificar suas ações, minimizando as consequências e atribuindo a responsabilidade a fatores externos.

In ecotoxicity, differences in species sensitivity can be expressed through a curve based on the distribution of pre-existing contaminant toxicity data, enabling better comparative visualization and the deduction of taxonomic groups more and less sensitive to toxic agentes. The objective of this work was to carry out, in a structured way, an investigation in the literature about the application of the species sensitivity distribution (SSD) curve in ecotoxicological analyzes of environmental matrices. To assist in this process of knowledge construction, an adaptation of the intervention instrument ProKnow-C was used, in order to select relevant articles and identify the characteristics of these publications that will scientifically contribute to the theme in question. The main results are the identification of quantitative data for the year of publication, countries and most relevant journals aligned with the proposed theme, the minimum number of data for the construction of the curve and its main applications, as well as identifying gaps for new scientific research, thus contributing to the more precise application of the SDS curve in ecotoxicological analyses.
