Count Data Regression Analysis: Concepts, Overdispersion Detection, Zero-Inflation Identification, And Applications With R, Luiz Paulo Fávero, Rafael De Freitas Souza, Patrícia Belfiore, Hamilton Luiz Corrêa, Michel F. C. Haddad

Practical Assessment, Research, and Evaluation

In this paper is proposed a straightforward model selection approach that indicates the most suitable count regression model based on relevant data characteristics. The proposed selection approach includes four of the most popular count regression models (i.e. Poisson, negative binomial, and respective zero-inflated frameworks). Moreover, it addresses two of the most relevant problems commonly found in real-world count datasets, namely overdispersion and zero-inflation. The entire selection approach may be performed using the programme language R, being all commands used throughout the paper availabe for practical purposes. It is worth mentioning that counting regression models are still not widespread within ...

Do They See A Half-Full Water Cooler? Relationships Among Group Optimism Composition, Group Performance, And Cohesion, William P. Jimenez, Xiaoxiao Hu, Chad Kenneally, Feng Wei

Psychology Faculty Publications

In the present study, relationships among group composition of trait optimism (the mean, standard deviation, and minimum and maximum scores of optimism), group cohesion, and three group performance variables (task performance, contextual performance, and creative performance) were examined. Multi-source data were collected from 56 workgroups including 202 group members and 56 group leaders. We found that the mean, maximum, and minimum operationalizations of group optimism composition were positively related to the three group performance variables and that group cohesion mediated the optimism–performance relationships for the mean and minimum operationalizations of group optimism. We recommend that practitioners generally consider selecting ...

Do Esg Mutual Funds Deliver On Their Promises?, Quinn Curtis, Jill E. Fisch, Adriana Z. Robertson

Faculty Scholarship at Penn Law

Corporations have received growing criticism for their role in climate change, perpetuating racial and gender inequality, and other pressing social issues. In response to these concerns, shareholders are increasingly focusing on environmental, social, and corporate governance (ESG) criteria in selecting investments, and asset managers are responding by offering a growing number of ESG mutual funds. The flow of assets into ESG is one of the most dramatic trends in asset management.

But are these funds giving investors what they promise? This question has attracted the attention of regulators, with the Department of Labor and the Securities and Exchange Commission (SEC ...


Examining Dimensions Of Patient Satisfaction With Telemedicine, Robert Garcia 2021 DePaul University

Examining Dimensions Of Patient Satisfaction With Telemedicine, Robert Garcia

College of Computing and Digital Media Dissertations

During the outbreak of the novel coronavirus (COVID-19) medical institutions and practitioners have drastically increased their adoption of telemedicine. The proliferation of telemedicine systems has sparked renewed interest among IS researchers in evaluating its usage. One of the main indicators used to measure the success of telemedicine services is patient satisfaction. Yet several problems exist with current methods used to evaluate telemedicine satisfaction. Patient satisfaction with telemedicine is frequently evaluated using either single question items or handmade instruments that are seldom assessed for validity. While telemedicine satisfaction is typically evaluated through single measures, satisfaction is considered a complex and multidimensional ...

BISNIS & BIROKRASI: Jurnal Ilmu Administrasi dan Organisasi

Illegal gold mining is a controversial activity. It provides livelihoods for rural communities in gold-rich areas and contributes to poverty alleviation; however, it also creates environmental devastation, losses to state revenue and often triggers social conflicts. Various eradication efforts have been made, ranging from persuasive approaches to harsh law enforcement involving the military and police, yet this illegal activity continues. This qualitative study aims to find and propose workable solutions to eradicate this activity, particularly in Indonesia. The study was conducted at two illegal- mining sites in Kalimantan, involving some 6,000 illegal-gold-miners. Data were collected through field observations and ...

What Can Indonesian Businesses Learn From The We Mean Business Initiative To Address Climate Change?, Erla Mychelisda, Nur Firdaus

BISNIS & BIROKRASI: Jurnal Ilmu Administrasi dan Organisasi

Climate change has been a much-discussed topic around the globe, and all stakeholders, including the business sector, must take collective and serious actions. The We Mean Business (WMB) initiative is a non-profit organisation that supports companies to develop policies and accelerate the transition to a low-carbon economy and achieve sustainable business. On the other hand, Indonesia, as one of the world biggest emitters and signed the Paris Agreement, are also required to meet its climate pledge. Unfortunately, not many Indonesian businesses have shown their contribution to climate change. This study aims to analyse the companies’ commitments under the WMB coalition ...


Vocation, Belonging, Courage: Gender Equity In Narratives Of Non-Exempt Women Administrative Assistants In Academic Units At The University Of Dayton, Julio A. Quintero, Heather Ashley 2021 University of Dayton

Vocation, Belonging, Courage: Gender Equity In Narratives Of Non-Exempt Women Administrative Assistants In Academic Units At The University Of Dayton, Julio A. Quintero, Heather Ashley

Reports from the Gender Equity Research Fellowship

Gender roles normalize thinking patterns, behaviors, actions, and attitudes. The workplace is not immune to their influence. Gender roles make certain labor invisible, either because it does not typically fit with the expectations of a determined gender group, or because it is deemed normal and therefore expected.

This report condenses the narratives of 11 non-exempt women administrative assistants at the University of Dayton in reference to how vocation, belonging, and courage are affected by gender. Based on the responses, the report proposes several approaches to equity, which is defined as the modifying of structures and practices that have intentionally or ...

رغم اختلاف تفسير الاقتصاديين لأثر التنمية المالية على النمو الاقتصادي ووجود من يعارض أو على الأقل يعتبر أن هناك مبالغة في وصف الدور الذي يمكن أن يلعبه النظام المالي في الاقتصاد استنادا إلى الآثار السلبية التي قد تولدها التنمية المالية، فإن الاتجاه السائد وأغلب الشواهد التجريبية ترى وجود علاقة إيجابية قوية بين التنمية المالية والنمو الاقتصادي، ساعد في إبرازها توظيف الاقتصاديين لنماذج النمو الداخلي في شرح كيفية تأثير وظائف النظام المالي على الأنشطة الحقيقية.

كما تتضح أهمية هذا الموضوع لاسيما في ضوء التحولات السريعة التي تشهدها الصناعة المالية عالميا واستفادتها بالقدر الأكبر من التطورات الحاصلة في مجال تكنولوجيات المعلومات ...
