Parasitoids of Delia planipalpis (Meigen) and Delia platura (Stein) (Diptera, Anthomyiidae) in Mexico
Authors: Nava-Ruiz Paulina , Meraz-Álvarez Ricardo , Valdez-Carrasco Jorge , Chávez-López Onésimo , Bautista-Martínez Néstor
Published: June 2021

Among the insect pests that affect crucifer crops in Mexico are Delia planipalpis (Meigen) and D. platura (Stein). They are a threat to the production of these vegetables since the damage they cause directly and indirectly affects yield, quality, and commercialization of these crops. Nevertheless, the existence of natural enemies of these dipterans is still unknown. It is fundamental to determine which parasitoids or predators can be considered possible biological control agents in an integrated pest management program.

The sampling sites were located in Guanajuato, Puebla, and the State of Mexico, where plants of Brassica oleracea L. var. italica Plenk and capitata L., B. napus L., and Raphanus sativus L. infested with Delia spp. were selected. The symptoms observed were wilting, yellowish, flaccid leaves and individuals less developed than the rest of the crop. These plants were extracted with their root and the surrounding soil. Also, wild crucifers were collected, such as Raphanus raphanistrum L., Brassica campestris L., and Sisymbrium irio L. The first records of Aphaereta pallipes Say (Hymenoptera, Braconidae), Trybliographa rapae (Westwood) (Hymenoptera, Figitidae), and Aleochara bimaculata Gravenhorst (Coleoptera, Staphylinidae) are reported parasitizing the puparia of these anthomyiid flies on cultivated and wild crucifers. This represents only a starting point for the continuous study of these parasitoids, which is needed to consider them useful for the biological control of D. planipalpis and D. platura.

Attitude Formation and Attitude Change
Authors: Srivastava Supriya , Rojhe Kuldeep Chand
Published: June 2021

The study of attitudes formation and attitude change are two defining features at the core of social psychology. An attitude is a set of beliefs that people hold in relation to an attitude object, where an attitude object is a person, a product, or a social group. Since attitudes have been a strong influence on human behavior, social psychologists have viewed attitudes as important to understand behavior of individuals. Firstly, the chapter will introduce the concept of attitude with social psychological perspective. Attitude formation is important to understand to know why people hold different attitudes and how attitudes help to predict their behavior. In the second section, distinct ways of attitudes formation are discussed. It is also important to understand how attitudes influence in decision making, which is also discussed in the next section of the chapter. In the later section, changing processes of attitudes have been discussed.
Deconstructing the Three Pillars of Evidence-Based Practice to Facilitate Social Justice Work in Speech Language and Hearing Sciences
Authors: Khamis-Dakwar Reem , Randazzo Melissa
Published: June 2021

This chapter reviews the limitations of the evidence-based practice (EBP) framework adopted by American Speech Language Hearing Association for the field of speech, language, and hearing sciences (SLHS) in addressing systemic racism. The authors argue that a shift from a medically-based EBP model to a pluralistic EBP model would better serve the needs of black, indigenous, people of color (BIPOC) with communication impairments in the current sociopolitical landscape. The authors examine the three pillars of EBP through the lens of social justice work. They describe how the current EBP model limits the development of social justice work in SLHS. They describe the need to refine the EBP model by validating the contribution of qualitative research as scientific evidence, reevaluating the basis of clinical expertise in client-clinician cultural mismatch, and address the importance of integrating policy and culture in consideration of client and family preferences. These transformations are critical in light of the under-representation of BIPOC clinicians in the field of SLHS profession.
Recruiting Faculty for Esports Programs in Academia
Authors: Reavis David
Published: June 2021

Recruiting faculty for an eSports program begins with a clear direction for the degree or certificate being offered. Using a strategic planning process helps set direction for new or existing programs. The planning process is complicated by the newness of eSports and the number of different disciplines that may be considered part of the umbrella that encompasses eSports. A shortage of faculty candidates with high-demand qualifications creates a recruiting challenge that may be overcome with recruiting methods that communicate the positive attributes of the institution and focus on the traits that individual candidates offer.
Risk Management and Risk Communication in the Case of Vector-Borne Disease
Authors: Blagica Sekovska , Jovana Stefanovska
Published: June 2021

Change in environmental and socio-economic, emerging zoonotic diseases will be an increasing challenge for public health in Europe and in Macedonia also. The risks and consequences triggered by vector-borne diseases (VBD) for public health in Macedonia are just starting to emerge in public awareness. This is clearly shown by recent events such as spread of hemorrhagic fevers in Europe. The term “public health” in the scope of this chapter suggests re-conceptualization of public health by adapting the risk governance framework developed by the International Risk Governance Council (IRGC) for this purpose. The IRGC approach is distinguished from more classical risk governance approaches, inter alia, by an explicit inclusion of a systematic concern assessment. However, unfortunately, not all countries are adapted on this innovative public health model. This chapter shows results of a risk management study based on interview in depth with the officials regard public health risk, in frame of one health concept in the Republic of Macedonia.

Published: June 2021

Due to the growing prominence of quality management systems in health, this article presents the theoretical background and the results of an empirical study conducted among the Institutes of public health in the Republic of Croatia, with the aim to determine the level of implementation of TQM principles. The research was based on a questionnaire built on the Kanji model. According to the quality managers' perception, all analyzed TQM principles have been implemented at high level. Although in general a high level of implementation exists, certain TQM principles have been implemented to a larger extent than others. The research was also focused on finding if the difference among QM managers' perceptions exists depending on the status of ISO 9001 (implemented/not implemented/plan to implement). The differences were found in relation to the activities connected with people-based management and continuous improvement. Based on the research results, specific areas of improvement, i.e. activities that foster implementation of TQM principles, are emphasized.
هل التعايش الديني يستلزم فقدان الهوية؟
Authors: د. حسن بن محمد ماخذي د. حسن بن محمد ماخذي
Published: June 2021

. لا شك أن للتعايش أهمية كُبرى كونه صمام الأمان للمجتمعات من التمزق والشتات، حيث انعدامه يؤدى إلى الحروب. كُتبت الكثير من المقالات حول التعايش لمعالجة مشكلة الصراعات التي كان السبب الرئيس في اذكاء نارها هو الاختلاف في الهوية وعدم قبول الأخر وكراهيته والنفور منه، مما أدى إلى إهلاك الحرث والنسل وإفساد الأرض وخرابها بدلاً من إعمارها. ركزت تلك الكتابات حول أهمية التعايش وضرورة قبول الأخر المختلف دينياً أو ثقافياً أو عرقياً، حتى لا يحصل الصدام والصراع الذي يؤدي إلى إزهاق الأرواح. في المقابل هناك فئة جديدة من المجتمع ظهرت مع انتشار وتوسع وسائل التواصل الاجتماعي ترى أن من أهم مقومات التعايش عدم التركيز على الاختلافات ونكرانها وإذابة الفوارق بين المختلفين لدرجة الانصهار في الأخر. يناقش البحث قيمة التعايش في المجتمعات متعددة الهويات والأعراق والثقافات والأديان، وأهمية التعايش في تلك المجتمعات التي تزخر بالتعددية، مع الحفاظ على الهوية والتميز عن الغير، كما تطرقت الورقة إلى تعريف التعايش والهوية اصطلاحاً. والسبب في تسليط الضوء على هذا الموضوع أمران، الأول: التقدم التقني الذي كان أحد نتائجه الانفتاح الثقافي الذي يشهده العالم اليوم، مما سهل التواصل والالتقاء بالثقافات الأخرى، والأمر الأخر هو خلط المفاهيم الذي أدى إلى الانسلاخ من الهوية بحجة التعايش، فبرزت فئة في المجتمع ترى ضرورة الذوبان في الأخر وذلك بالدعوة للتعايش من خلال إلغاء الفوارق حسب اعتقادهم. وقد تبين من خلال البحث أهمية الحفاظ على الهوية كونها هي الحاضنة للتعايش البناء الإيجابي، فبيئة التعايش هي التميز بالهوية والتفرد عن الأخر لا الانصهار والذوبان.

Authors: Soriano Gil
Published: June 2021

Purpose: Assessment of the cultural competence of nurses is becoming an important parameter in assessing the provision of quality care to patients especially in multicultural populations such as the Philippines. The study was conducted to assess the construct validity and internal consistency reliability of the Nurse Cultural Competence Scale (NCCS) among Filipino nurses. Methods: A methodological study was utilized and a convenience sample of 124 Filipino nurses were included in the study. An exploratory factor analysis was used to assess the construct validity of the instrument while internal consistency reliability was determined using Cronbach’s α coefficient and item-total correlations. Results: The 20-item NCCS was loaded on one dimension with factor loadings ranging from 0.72 to 0.95, explaining 79.19% of the total variance. Cronbach’s α was 0.986 which demonstrated high reliability and item-total correlations were between 0.811 and 0.929. Conclusion: The NCCS is a reliable and valid instrument for the measurement of cultural competencies among Filipino nurses.

The use of measurable traits of trunk and crown to assess the biosocial classes of oak trees (Quercus robur L.)
Authors: Zawieja Bogna , Turczański Krzysztof , Najgrakowski Tomasz , Kaźmierczak Katarzyna
Published: June 2021

The crown class assessment is a key element in forestry practice. It is a traditional method that finds application in thinning plans, assessment of site index, tree competition, or crown condition. Assigning trees into a given class is done during field surveys and requires precision and experience to avoid inaccuracy. Therefore, Kraft’s system has often been criticized and modified. Thus, in our study, we aimed to analyse whether the directly measured traits of trunk and crown of oak trees (Quercus robur L.) can be applied to crown class assessment. For this purpose, we used the principal component analysis (PCA) and nonlinear kernel principal component analysis (KPCA) based on measurable traits of trunk and crown, i.e., the height of the tree, the diameter at breast height, the length of the crown, and the field crown projection area. In total, we measured 286 mature trees in three oak stands located in western Poland. Results indicate that all chosen traits of trunk and crown allowed, though not always perfect, to assign the trees into given crown classes. The greatest contribution to crown class distinction had the diameter at breast height and the parameters of crown, i.e., and the field crown projection area. Furthermore, results show that the best method of assigning the trees into biosocial classes is the KPCA Gauss, considering the percentage explanation of the total variability, and KPCA Laplace, considering the visual division. In the latter, the multivariate analysis resulted in a similar crown class assignment as the field-assigned method. However, its application requires measurements that make it neither cheaper nor faster than a traditional crown class assessment. It indicates that a traditional field-assigned method, despite its subjectivity, should continue to be of great importance in forestry practice. Moreover, the alternative traits of trunk and crown can be a potentially useful statistical substitute for crown class assessment. Keywords: crown class, oak stand, trunk and crown traits, multivariate methods

The subject of the study is the study of technically possible localization options for the contrailer terminal. The relevance is related to the practical need to improve the organization of the station through its track and territorial development.Used analytical, design methods, evolutionary and functional approach.Using the evolutionary-functional approach, alternative, technically possible options for improving the operation of the station were identified, taking into account the location of the contrailer terminal as part of the transport hub.The possible options for the station’s development were critically evaluated. It was found that option 1 is located close to the station and requires minimal time to perform shunting operations. The advantages of option 2: the proximity of a year-round working seaport; a large free area for construction and no intersection with the main tracks of the station. It is noted that the final decision is possible only after the economic assessment of the options.

The conclusion that can be drawn broadly is that existing research creates a new model that not all research related to leadership has a strong influence on lecturer performance, what is unique is that these differences are in the State of Indonesia not in foreign countries, namely Russia, and the type of leadership is only leadership general public that has no relationship with the performance of the lecturers other than that which has a very strong relationship.
SELF-ESTEEM AND DEPRESSION AMONG VIETNAMESE UNIVERSITY STUDENTS
Authors: Ho Thi Truc Quynh , Hoang The Hai
Published: June 2021

Research and theories on gender differences in self-esteem and depression as well as the relationship between self-esteem and depression play an important role in the field of psychology. In the current study, we explore these two issues with Vietnamese university students. The levels of self-esteem and depression were assessed with a sample of 859 university students drawn from three universities in central Vietnam. The results showed that Vietnamese university students have moderate self-esteem and most do not suffer from depression. As expected, the male students reported significantly higher self-esteem than theirfemale fellows; however, the female students reported higher levels of depression than the male ones. The results also revealed that self-esteem was negatively correlated with depression. The research contributes to the understanding of the gender differences between the two mental health factors and the relationship between them among Vietnamese university students. These findings are important to the development of intervention strategies that help improve self-esteem and prevent depression in university students.
THE EFFECT OF THE COVID-19 PANDEMIC RISK PERCEPTION ON STUDENTS' BEHAVIOURAL INTENTION TOWARDS RETURNING HOME FOR STUDYING
Authors: Bui Huynh Nguyen , Nam Phuong Phung
Published: June 2021

Due to the COVID-19 crisis, it is more difficult for international students to complete their study abroad. There has been little discussion concerning international students' perspectives regarding their study plan during this health-related crisis. Based on the frameworks of risk perception theory and the extended Theory of Planned Behaviour, this study highlights returning home for studying as a health-protective behaviour stemming from international students' perceptions of COVID-19 risk. In other words, overseas students' behavioural intention is scrutinized through the lens of the risk perception. An online survey with random sampling method was administered to the Vietnamese students who were studying in the UK in February and March 2021. A total of 588 responses were collected for data analysis. The results reveal that international students' cognitive and affective risk perceptions are positively related to their attitude, subjective norms and perceived behavioural control over returning home for studying. There also exists a significant influence of both cognitive and affective risk perceptions on the students’ behavioural intention. Attitude, subject norms, and perceived behavioural control are considered significant mediators between risk perception and behavioural intention.

A EXPANSÃO PRODUTIVA AGROPECUÁRIA NO ESTADO DE MATO GROSSO E SEUS IMPACTOS FUNDIÁRIOS E AMBIENTAIS A PARTIR DOS ANOS 2000 / Agricultural productive expansion in the State of Mato Grosso and its fundial and environmental impacts from 2000
Authors: Heck Cláudia Regina
Published: June 2021

O estado de Mato Grosso atingiu elevados índices de produtividade tornando-se um dos principais estados produtores de commodities do país. Com isso, sua estrutura produtiva agropecuária tem se assumido, cada vez mais, características de concentração fundiária e de especialização produtiva, baseada na intensificação do uso de capital. Todavia, tais mudanças repercutem sobre o espaço rural, com impactos sobre o uso da terra e o meio ambiente. O presente artigo tem como objetivo discutir aspecto da expansão produtiva agropecuária no Mato Grosso e seus impactos fundiários e ambientais. Utiliza-se como fundamento analítico o método histórico-estrutural, através do estudo de variáveis consideradas determinantes da produção, desde o início dos anos 2000. A análise reforçou que há uma rigidez da estrutura produtiva que impacta no aumento da concentração fundiária e no uso intensivo de capital com efeito na elevação dos preços da terra, no uso de insumos de produção, máquinas e equipamentos e no avanço de lavouras temporárias, com demanda vinculada ao mercado externo, que refletem em externalidades ambientais negativas, em especial, no aumento do uso de agrotóxicos. Finalmente, não se deixou de observar que tais condições se apresentam como limitantes do desenvolvimento - e não apenas crescimento – local.

A tomada de decisão financeira é um dos aspectos estudados pelas Finanças Comportamentais, que partem do pressuposto da racionalidade limitada dos indivíduos. Considerando especificamente os estudantes, pode-se compreender a validade dos julgamentos realizados, sendo um auxílio na atuação profissional dos mesmos. Assim, o presente estudo buscou analisar os vieses comportamentais de aversão à perda e excesso de confiança nos estudantes do Curso de Administração de uma Universidade do Rio Grande do Sul sob a ótica do gênero. O primeiro viés faz com que os indivíduos corram riscos mais freqüentes em suas decisões, já o segundo, faz com que os mesmos confiem mais do que deveriam em seus próprios conhecimentos e opiniões. Realizou-se uma pesquisa survey composta por 81 respondentes, a partir de um questionário estruturado, o qual abordou os vieses comportamentais e questões de perfil. Por meio da análise foi possível observar que os estudantes possuem os vieses analisados e que estes afetam a tomada de decisão. Sob a ótica do gênero, percebeu-se que não há diferença.
“Vai uma Carona, aí?”: Experiências de consumo colaborativo de usuários de aplicativo de caronas
Authors: Sousa Júnior João Henriques de
Published: June 2021

Apesar de ser um fenômeno recente, o consumo colaborativo já é uma forma de negócio bastante popularizada devido à facilidade e agilidade do acesso proporcionada pela internet. Por ser uma área ainda iniciante nas pesquisas acadêmicas, pouco ainda se sabe sobre como os consumidores respondem às diversas formas deste consumo. Assim, o presente artigo objetiva analisar a experiência de consumo de usuários de aplicativo de carona. Para isso foram realizadas entrevistas semiestruturadas com passageiros e motoristas do aplicativo BlaBlaCar, analisadas a partir da técnica de análise de conteúdo temática. Os resultados apontam que as experiências são positivas, tendo sido destacados entre os passageiros como principais benefícios: preço e comodidade, e para os motoristas: economia e lucro. Além destes, a segurança a partir de informações do motorista e demais passageiros disponíveis no aplicativo também contribuem para que este seja tido como uma alternativa viável para viagens mais econômicas.

Published: June 2021

Este estudo objetiva entender, no modelo de negócio da empresa Uber, como os colaboradores entendem o sentido de consumo colaborativo proposto pela organização. Dado que o modelo de negócio em estudo provocou uma disrupção no comportamento do consumidor, é imprescindível entender a visão do prestador do serviço, no caso o motorista, pois este também é considerado um consumidor pela empresa. Para tanto, foram realizadas entrevistas com motoristas que ofertam o serviço por meio do aplicativo, e realizando-se a análise interpretativa de seus discursos, concluiu-se que não há uma percepção, pelo menos não em sua totalidade, por parte deles do princípio colaborativo que deu origem ao negócio. A principal implicação gerencial se dá na mudança de visão que o negócio deve possuir dos motoristas, parceiros de negócio.

A modelling approach to elephant and tree population dynamics for a small game farm
Authors:   , Stretch Anne-Marie
Published: June 2021

Throughout Africa, growing human populations and resulting loss of wildlife habitat is a critical issue for most animal species. It is more and more common for privately owned small or medium sized farms to reintroduce wildlife on their land and such protected areas are fast becoming the only refuges available to wild animals. However a comprehensive understanding of the complex ecological processes taking place is vital for the effective management of restricted areas and the conservation of biodiversity. Due to the enormous complexity of an ecological system and the long periods of the related dynamics, it is very difficult to analyse the interaction between animals and plant populations without suitable computer models. In this thesis, the dynamics between elephant and trees (a major food source) are considered using computer simulations.
Stakeholders’ perceptions of environmental injustices and of community-based environmental education : a case study of the Stortplaats community in KwaZulu Natal
Authors:   , Ndlovu Emmanuel
Published: June 2021

The purpose of this study was to investigate stakeholders’ perceptions of environmental injustices and of community-based environmental education at Stortplaats, in order to address the injustices through community-based environmental education. Environmental injustice is a phenomenon that entails the unfair distribution of environmental burdens, disproportionately exposing human life to environmental hazards. Communities in poor socio-economic circumstances are excessively exposed to negative environmental burdens such as sewage oxidation ponds, pollution, unprecedented land degradation due to sand poaching and inadequate infrastructure. Stortplaats faces such an oppressive environment. It was historically created by apartheid, but the current system seems to be paying minimum attention to corrective services. The stakeholder theory, environmental perception framework, place attachment theory and community-based environmental education model were used as frames of reference for this study. This study was informed by the interpretivist paradigm and the case study research design was adopted. A qualitative research approach was used. Convenience and purposive sampling were used to sample 25 participants who included five learners above 18 years, five educators, 10 community members, the chief, the community head, the councillor, a business person and the environmental health officer. Semi-structured individual interview schedules were utilised to gather data. These were complemented by photovoice narrations and indirect observation. A thematic data-analysis approach was used to analyse generated data. The key findings of the study indicate that apartheid contours are still visible at Stortplaats and postapartheid promises have not been kept. The findings also show that some community members lack knowledge about environmental policies and this results in irresponsible environmental behaviour. There is also lack of effective communication between leaders and community members, leading to struggles for power and recognition and causing poor service delivery. Finally, the findings show a need for community-based environmental education to address environmental injustices in Stortplaats.
Challenges and Opportunities for the Future of Media and Mass Communication Theory and Research: Positionality, Integrative Research, and Public Scholarship
Authors: Deuze Mark
Published: June 2021

In this essay I intend to tell a story of media studies and mass communication research as a field, based on the work of the late Denis McQuail – and that of editing the new edition of his seminal handbook McQuail’s Media and Mass Communication Theory (McQuail & Deuze, 2020). Using McQuail’s historical storytelling method, I specifically look at the challenge for the field in the context of a global pandemic alongside an infodemic, at a time when the whole world faces the consequences of recurrent lockdowns, social distancing measures, and institutional pressures to stay at home. Media studies and (mass) communication research, while having a distinct narrative, as a field has only just begun to articulate its relevance to society – we have only just started to tell our story. Using developments in understanding the self as a research tool, the implementation of integrative research designs, and calls for engaged and public scholarship, the paper outlines challenges and opportunities for what we can do with our field.
Den kristna etikens dubbla utmaning
Authors: Åsberg Samuel
Published: June 2021

Christian social ethics has long endured a polarizing debate between a universal ethics based in creation, often framed in terms of reason or natural law, and an ecclesial ethics based in revelation. With no satisfactory conclusion to the debate in sight, and adding to it an exceedingly complex cultural situation in which to navigate, many seek to find new ways of framing the alternatives. The "twin challenge" of Christian social ethics in a pluralistic and post-secular setting is here identified as articulating a social ethics that acknowledges the tensions between the specificities of the Gospel and culture while simultaneously providing a framework and resources for building a common life across confessional borders. One way of addressing this challenge is to ground ethics in the Trinity. While creational ethics generally emphasize the first article of the creed, an ecclesial ethics tend to focus on the latter two. Grounding Christian ethics in the Trinity is an attempt at a holistic approach, tending to both particular and universal concerns. One such effort is found in Carl-Henric Grenholm's attempt at articulating a contemporary Lutheran social ethics grounded in a trinitarian framework. By way of identifying a number of tensions within Grenholm's proposal, this article offers some pointers on the requirements of a trinitarian ethics in a pluralistic and post-secular context. It argues for a more complex construal of secularity and the need for a robust Christology and eschatology to provide a critical lens on culture. Furthermore, it highlights the importance of on-going, complex negotiations beyond secular matrices and communities of virtuous actors capable of performing them.

Objective: Spontaneous abortion is the most common complication of early pregnancy, affecting up to 20% of recognized pregnancies. Kisspeptin is predominantly released by placental syncytiotrophoblasts, and regulates their placental invasion into the uterine matrices. We aimed to establish an association of serum kisspeptin levels with pregnancy outcomes during the early gestational stage of the first trimester. Method: In this prospective study, 90 pregnant women in their 7 to 8 6/7 gestational weeks were classified into three groups: (i) The control group, consisting of healthy pregnant women (n=30), (ii) the threatened abortion group (n=30), and (iii) the spontaneous abortion group (n=30). The maternal serum samples were analyzed for complete blood count parameters and kisspeptin levels. Results: There was no statistical difference regarding body mass index (BMI) and gestational age (p=0.370). Regarding detailed obstetric notations, including gravida, parity, abortion, and living children, socioeconomic levels, and employment rates, all study groups were comparable (p>0.05, for all). No significant association was found regarding the biochemical parameters of complete blood count, including neutrophil, lymphocyte, and platelet concentrations, as well as neutrophil-to-lymphocyte ratios (NLR) and platelet-to-lymphocyte ratios (PLR) (p>0.05, for all). The median serum kisspeptin levels of the study groups did not differ between the groups (p=0.153). Correlation analysis revealed no significant relationship between serum kisspeptin levels and other study parameters in any study groups (p>0.05, for all) Conclusions: We found no statistically significant relationship between serum kisspeptin concentrations and pregnancy outcomes in the early gestational stage of the first trimester, and serum kisspeptin concentrations did not seem to be a reliable marker to distinguish abortion status from viable pregnancy

Objective: To investigate whether partial arterial carbon dioxide pressure (PaCO2) level in arterial blood gas analysis that was used to predict nocturnal hypoventilation (NH) is concordant with nocturnal end-tidal CO2 (PetCO2) measurement obtained by a noninvasive method of oxycapnography in children with neuromuscular disease (NMD). Methods: Twenty-one patients aged 6-18 years with a confirmed diagnosis of NMD were enrolled. Each patient underwent a nocturnal oxycapnography study using an orinasal probe and a pulse oximetry finger probe to record PetCO2, oxygen saturation (SpO2), pulse rate, and respiratory rate. Arterial blood gas analysis was performed to record PaCO2 levels on three occasions at night (23: 00 pm, 03: 00 am, 07: 00 am). Results: The mean overnight PaCO2 level of the three blood gas analyses (mean PaCO2noct) was 41.78±4.69 mmHg. A significant change was observed between mean PaCO2 23: 00 and PaCO2 07: 00 levels (p=0.032). There was no significant difference between PaCO2, PetCO2, and SpO2 levels in the NMD group. The interclass correlation coefficient between PaCO2 07: 00 and PetCO2 levels was 0.791 (95% CI: 0.533-0.923); the interclass correlation coefficient between overnight mean PaCO2 and PetCO2 levels was 0.811 (95% CI: 0.533-0.923). Conclusion: Our study indicates that nocturnal PetCO2 and PaCO2 levels were statistically comparable but the use of PaCO2 alone is not adequate to make an early diagnosis of NH in NMD. There is a need for making more restrictive definitions for NH, and conducting studies with larger study populations to reach an agreement on the best definition of hypoventilation, and updating consensus guidelines.

A quantitative research approach was adopted. Sampling technique adopted was convenient sampling. Sample size was 100. The investigators assessed undergraduate college students using questionnaires on frustration and family climate. The study showed that 23% of students had high frustration, 46% had moderate frustration and 31% had low frustration. 29% of students had unfavorable family climate 52% had moderate family climate and 19% favorable family climate. There was no association found between frustration and selected demographic variables. But an association was found between family climate and selected demographic variables such as age, type of family and type of residence. There was no association found between family climate and selected demographic variables such as sex, education of parent, occupation of parent, monthly income of parent and type of course. The value of r was -0.09. So, there was a slight negative correlation between frustration and family climate. The relationship between the two variables is weak. That is when family climate become favorable frustration decreases and vice versa.
