Chemistry Experiment

ABSTRACTA general chemistry experiment has been adapted in which electrochemical principles in fuel cells are applied to the curriculum, thus bringing research into the classroom. It is well documented that students struggle in understanding redox reactions, in particular when applied to an electrochemical cell. There are three basic concepts needed to analyze these energy devices: anode, cathode and electrolyte.In the proposed experiment, undergraduate students explored the role on an electrolyte in an electrochemical cell. Inquiry based methods were used to introduce the experiment. Explanations of fundamental electrochemical concepts involved in fuel cells were introduced to the students with pre- and post-laboratory activities and experimental results discussions. The lesson for the experiment “role of an electrolyte in an electrochemical cell” was planned to improve students’ technological skills and application of knowledge acquired in daily life. The battery was made using household materials: zinc, copper and napkin paper soaked in different electrolyte solutions. Students correlated the voltage of the cells with the substances being used in the experiment and classified these as strong electrolyte, weak electrolyte or non electrolyte. A variety of assessment tools were designed and incorporated during the experience to probe students understanding in the main topics and to identify the struggles during their learning process.

Injury Assessment

It has been widely accepted that the assessment of balance after concussion plays a large role in determining deficit. Qualitative balance assessments have been an established piece of the post-injury assessment as a clinical behavioral marker of concussion for many years. Recently more specific guidelines outlining the role of balance evaluation in concussion identification and management have been developed as part of concussion management tools. As part of the ongoing development of concussions protocols, quantitative assessment of balance function following concussion has also been identified to have an important role. Frequently imbalance and dizziness reported following concussion is assumed to be associated with post-concussion syndrome (PCS). While imbalance and dizziness are common complaints in PCS, they can also be a sign of additional underlying pathology. In cases of specific dizziness symptoms or limited balance recovery beyond the initial post-concussive period, a quantitative vestibular assessment may also be needed. Electronystagmography and videonystagmography (ENG/VNG), rotary chair testing (RCT), and vestibular evoked myogenic potentials (VEMPs) have all been identified as valid assessment tools for vestibular dysfunction following traumatic brain injury (TBI). The assessment of balance and dizziness following sports-related concussions is an integral piece of the puzzle for removal from play, assessment of severity, and management.

This study demonstrates the significance of individual difference factors, particularly gender and sensation seeking, in predicting media choice (examined through hypothetical descriptions of films that participants anticipated they would view). This study used a 2 (Positive mood/negative mood) × 2 (High arousal/low arousal) within-subject design with 544 undergraduate students recruited from a large northeastern university in the United States. Results showed that happy films and high arousal films were preferred over sad films and low-arousal films, respectively. In terms of gender differences, female viewers reported a greater preference than male viewers for happy-mood films. Also, male viewers reported a greater preference for high-arousal films compared to female viewers, and female viewers reported a greater preference for low-arousal films compared to male viewers. Finally, high sensation seekers reported a preference for high-arousal films. Implications for research design and importance of exploring media characteristics are discussed.

The Relationship

Research on social and environmental accounting (SEA) has mainly concentrated on disclosure of SEA by corporate bodies, where investigations on ones attitude towards SEA are rarely discussed. SEA is a medium that develops relationships between business and society, community and nature. In addition, SEA involves a concept of sustain ability; where natural resources need to be sustained for the needs of future generations (Alhabshi et al., 2003). SEA also tries to recognise the role of accounting in sustainable development and the use of environmental resources. There are arguments that the young generations today are not fully aware of preserving these natural resources as well as handling social and environmental issues wisely. This perhaps link closely to their belief and cultural background. Hence, this paper examines the influence of gender and belief factors on the undergraduate students’ attitude towards SEA. Four dimensions of belief (fixed ability, quick learning, simple knowledge and certain knowledge) proposed by Schommer (2005) were adapted to analyse how belief factors have influence on their attitude towards SEA. An independent sample t-test was used to examine the relationship between gender and students’ attitude towards SEA. Spearmen’s correlation was employed to show the relationship between belief and attitude towards SEA. The results revealed that gender differences did not show influences on their attitude towards SEA. It was found that there is a significant relationship between belief and students’ attitude towards SEA. Students who believe on the importance of SEA tend to report positive attitude towards SEA. Perhaps findings of this study may provide some information on the SEA education and further be incorporated in the syllabus.

The Impact

This study aims to investigate the impact of parental career behaviors on undergraduate student’s career exploration and the mediating role of career self-efficacy. In the literature it is suggested that some social and individual factors facilitate students’ career exploration. Therefore, parental career behaviors and career self-efficacy is considered as predictors of student’s career exploration attitudes within the scope of the study. In this respect, data which are collected from 405 undergraduate students having an education on tourism and hotel management field by the survey method are analyzed by using the structural equation modeling. The results of the study indicate that parental career behaviors which are addressed support; interference and lack of engagement have a significant effect on student’s career exploration behaviors such as intended-systematic exploration, environment exploration and self-exploration. In addition, it has been found that one of the dimensions of parental career behaviors addressed as a lack of engagement has a significant effect on career self-efficacy levels of students. However, research results indicate that student’s career self-efficacy has a significant effect on only the self-exploration dimension. On the other hand, career self-efficacy has a partial mediating role between lack of engagement attitudes of parents and career exploration behaviors of students.

The Relationship

Colleges and universities have begun using the language of vocation and calling to help undergraduates think about the future direction of their lives. This language has been employed in both secular and religious contexts, but it has deep roots in a specific theological tradition. Given the increasingly multi-faith context of undergraduate life, many have asked whether this originally Christian terminology can truly become a new vocabulary for higher education. This volume’s 13 contributing scholars identify with a wide variety of faith traditions, including Buddhism, Christianity, Hinduism, Islam, Judaism, and Sikhism. Some claim more than one tradition; others would claim none. Rather than seeking to “translate” Christian language into other perspectives, they reflect on various facets of vocation from the standpoint of their own traditions. Both individually and collectively, they seek to expand the range of vocational reflection and discernment well beyond its traditional Christian origins, addressing themes such as religious pluralism and difference, the importance of multiple voices, the role of affective learning, the relationship between process and result, and the development of an integrated life. The authors recognize that all undergraduate students—regardless of their academic field, religious background, or demographic identity—need to make space for reflection, to overcome obstacles to vocational discernment, and to consider the significance of their own narratives, beliefs, and practices. Accomplishing these goals will require college campuses to reimagine their curricular and co-curricular programming in order to support their students’ interfaith reflections on issues of meaning and purpose, as well as personal identity.

This study explored psychological predictors that may impact viewers’ decision to watch television shows on the basis of perceived racial or ethnic representation. 1998 undergraduate students selected from a list of motivations for watching television that included race-specific motivations such as “a character is of my race/ethnicity.” Participants also completed attitudinal measures of colorblind racial ideology, social dominance orientation, ethnic identity, and ethnic stigma consciousness. Analysis revealed that prejudicial beliefs predicted less salience for racial representation when making choices about television watching, while deeper connection to one’s ethnic group predicted greater salience for representation when making these choices.

AbstractWork experiences during undergraduate studies can be remarkable in the journey of undergraduate students. The objective of this study was to assess, by analyzing semantic networks, the role of work experiences in the meanings those individuals attribute to professional identity. The sample consisted of 2291 students (60% women) divided into three groups: do not work, work in a field related to their course, work in a field not related to their course. The semantic networks of these groups were composed of words uttered from the professional identity prime. We chose to work with the critical network, obtained from the analysis of the incidence-fidelity indexes of the word pairs. The results evidence that work experiences are related to how undergraduate students attribute meaning to professional identity, in such a way that three different networks were formed for these groups. The network of those who work outside their field was the only one that integrated words with negative content, while the semantic networks of those who do not work and those who work in their field, despite containing words that do not always coincide, present a similar macrostructure. We conclude that work experiences play an important role in the meanings that undergraduate students attribute to professional identity. The study innovates by revealing elements of professional-identity construction, besides allowing for reflections on the effects of work experiences during the college period.

The One

This paper is built on the following research questions: (i) What are the direct/indirect relationships between Sustainable Development Goal 11 (SDG11) and sustainability protocols? (ii) Could the sustainability protocols constitute a solution towards the achievement of SDG11? We underline that, on the one hand, the SDGs are guidelines to support the development of sustainable policies and thus address all elements that may affect them, and on the other hand, sustainability protocols are assessment tools to promote sustainability-conscious design while remaining focused on the built environment. In the Italian regulatory context, the paper highlights how this difference in terms of focus and scale means that they only overlap and mutually reinforce each other with regard to certain aspects, more related to energy and air pollution issues and less to the social aspects of sustainability. Even if there is not always a direct relationship between the evaluation criteria of the protocols and the indicators of SDG11, it is possible to conclude that the sustainability protocols can facilitate the achievement of the SDG11 targets, acting as a key for the implementation of sustainable cities and helping in structuring the process leading to sustainability in a broader framework.
