This paper considers challenges of Human Resource Management (HRM) in Open Innovation processes. It examines which strategies managers used to overcome these problems in the case of the Brazilian Oil and Gas company Petrobras. By conducting an inductive case study it develops a contextual model based on the use of grounded theory. It argues that the most important categories were to overcome problems of (a) the interpersonal relationship, (b) power shifting inside the organization, and (c) making people more valuable to the organization and shows how managers tackled these challenges. It contributes with a deep analysis of HRM challenges in Open Innovation that is important for a better understanding of management problems that can come along with Open Innovation processes.; Este artigo leva em consideração os desafios da Gestão de Recursos Humanos (HRM) em processos de Inovação Aberta. São examinadas quais estratégias os gerentes utilizavam para superar esses problemas no caso da companhia brasileira de óleo e gás, Petrobrás. Ao conduzir um indutivo estudo de caso, é desenvolvido um modelo contextual baseado no uso da teoria fundamentada. Argumenta-se que as categorias mais importantes a serem superadas foram (a) as relações interpessoais...

The International HapMap Project provides a key resource of genotypic data on human lymphoblastoid cell lines derived from four major world populations of European, African, Chinese and Japanese ancestry for researchers to associate with various phenotypic data to find genes affecting health, disease and response to drugs. Recently, the HapMap resource has significantly benefited research areas such as gene expression variation studies. Besides some intrinsic limitations, there are a few challenges that should be considered in the next wave of research using this tremendous resource. We suggest that overcoming these challenges or considering the confounding variables in the interpretation of results can provide more insights into the current views of the human genome as well as complex traits such as drug response variation and susceptibility to common diseases.

As Canada’s newcomer student population continues to rise and 42% of total new immigrants settle in Ontario (Canwest News Service, 2009), it becomes increasingly important to ensure that these students are adapting well and to their full potential within their host schools. The purpose of this project was two-fold: first, to review the existing literature on immigrant and refugee students’ challenges in the classroom and school community and second, to develop a teacher`s manual based on the documented challenges specific to newcomer students in the classroom, so that these teachers can be aware of these possible challenges, as well as use suggested pedagogical strategies to address these challenges. For the purposes of my project, I first investigated the challenges specific to immigrant students, followed by the challenges experienced by refugee students in the classroom and community. I then surveyed the literature to identify what the research classifies as pedagogical strategies directed towards classroom teachers who are working with these students. Findings from my review of the literature indicated that trauma, grief, and loss; learning the English language; and the intercultural experience are the three main areas of challenge for both immigrant and refugee students. Overarching educational policies...

peer-reviewed; With the expansion of national markets beyond geographical limits, success of any business often depends on using software for competitive advantage. Furthermore, as technological boundaries are expanding, projects distributed across different geographical locations have become a norm for the software solution providers. Nevertheless, when implementing Global Software Development (GSD), organizations continue to face challenges in adhering to the development life cycle. The advent of the internet has supported GSD by bringing new concepts and opportunities resulting in benefits such as scalability, flexibility, independence, reduced cost, resource pools, and usage tracking. It has also caused the emergence of new challenges in the way software is being delivered to stakeholders. Application software and data on the cloud is accessed through services which follow SOA (Service Oriented Architecture) principles. In this paper, we present the challenges encountered in globally dispersed software projects. Based on goals mutually shared between GSD and the cloud computing paradigm, we propose to exploit cloud computing characteristics and privileges both as a product and as a process to improve GSD.

peer-reviewed; Follow-the-sun (FTS) software development is a strategy used to reduce the length of software projects that are developed across globally distributed locations. However, due to communication and collaboration challenges, software companies find it difficult to adopt this development strategy during task allocation and daily project handovers. In this study, we present results from a Systematic Literature Review (SLR) performed on papers published between 1990 and 2012. Our goal was to identify best practices and challenges for FTS implementation. We found 36 best practices and 17 challenges for FTS. These results are discussed in this paper in order to indicate opportunities for future research and make our results useful for the project managers.

Component-Based Software Development has become a popular approach to building software intensive systems. Besides using Commercial Off-The-Shelf components, an organization may choose to use Open Source Software components. Using OSS has been reported to have many benefits, but there are also challenges involved. Understanding the potential challenges of using OSS in developing products is important for practitioners, so they become aware of them and can anticipate them and take appropriate measures to address these challenges. We have performed a thorough review of the literature to identify challenges that may arise, as reported in the literature. This paper presents and discusses these findings. Researchers can discuss potential causes and solutions of our synthesized findings as well as benefit from provided references to literature on OSS challenges as input for future research.; Klaas-Jan Stol, Muhammad Ali Babar; This workshop was conducted as part of the ACM/IEEE 32nd International Conference on Software Engineering

Increased public awareness of immigration issues creates challenges for Latinos and the deportation of undocumented immigrants in record numbers is a source of worry in the Latino community in the U.S. Very few studies have examined how the preceding factors impact the lives and outlook of Latinos-specifically their quality of life, their confidence in the future, and their situation in the U.S. Using large nationally representative data, it was found that the challenges posed by increased public awareness of immigration issues and the worries associated with immigration indeed negatively affected the lives and outlook of Latinos. It was found that challenges and worries had independent and additive effects on the dependent variables. Further, deportation worries affected quality of life and/or situation in the U.S. for Latinos who were citizens and non-citizens.; La deportación de inmigrantes indocumentados en cantidades récord es una fuente de preocupación en la comunidad Latina en los Estados Unidos. Además, el aumento de la concienciación de los ciudadanos sobre las cuestiones de inmigración crea retos para los latinos.

The trend of green consumerism and increased standardization of environmental regulations has driven multinational corporations (MNCs) to seek standardization of environmental practices or at least seek to be associated with such behavior. In fact, many firms are seeking to free ride on this global green movement, without having the actual ecological footprint to substantiate their environmental claims. While scholars have articulated the benefits from such optimization of uniform global green operations, the challenges for MNCs to control and implement such operations are understudied. For firms to translate environmental commitment to actual performance, the obstacles are substantial, particularly for the MNC. This is attributed to headquarters’ (HQ) control challenges (1) in managing core elements of the corporate environmental management (CEM) process and specifically matching verbal commitment and policy with ecological performance and by (2) the fact that the MNC operates in multiple markets and the HQ is required to implement policy across complex subsidiary networks consisting of diverse and distant units. Drawing from the literature on HQ challenges of MNC management and control, this study examines (1) how core components of the CEM process impact optimization of global environmental performance (GEP) and then uses network theory to examine how (2) a subsidiary network’s dimensions can present challenges to the implementation of green management policies. It presents a framework for CEM which includes (1) MNCs’ Verbal environmental commitment...

Africa's financial systems face challenges across many dimensions, as discussed in the report financing Africa: through the crisis and beyond. The analysis in that report was based partly on several detailed background papers that are included in this volume. The next six chapters are written by experts in their respective areas and provide an in-depth analysis of these challenges and present possible solutions. In this introduction, the authors provide an overview of the different chapters and how they are related to each other and the main volume. The three chapters in first part focus on key challenges concerned with access to financial services, including financial and operational deficiencies in the microfinance market, reaping the benefits from the technological revolution of retail banking, and deepening and broadening agricultural finance across Africa. The three chapters thus each cover different aspects with a different focus, ranging from an institutional approach to a focus on innovation as a driver of financial broadening to an important element of financial infrastructure to a specific sector. The second part includes the fourth chapter...

peer-reviewed; Large legacy systems that have been in use for several decades need to evolve in order to take advantage of new technological advances. One such development is the emergence of multi-core processors and parallel platforms. However, the evolution of code written for single-core platforms into code that can take advantage of multi-core technology is challenging. The aim of this research is to explore the challenges that parallel programmers face in the evolution of existing software to exploit multicore and parallel architectures. A review of the current literature was conducted and ten frequently reported challenges were identified. It is important to raise awareness of potential challenges that practitioners may face when evolving sequential code to exploit multicore platforms in order to be better prepared for future evolution. The research community can use these results to develop a research agenda in order to design and develop solutions to address these challenges; SFI grant 10/CE/I1855

This is a case study of the challenges and complexities of initiating a professional learning community of teachers. Situated in a school in the British West Indies, this study draws on the experiences of seven teachers initiating a professional learning community (PLC) over a 12-week term in 2007. Individual interviews, group meetings, journal entries, and exit comments were analyzed to construct five main themes: Initiating a PLC, Features of a PLC, Challenges of a PLC, Benefits of a PLC, and the Future of the PLC. These teachers recognized the need for this community because of challenges and problems they faced. Many features reported in the literature on PLCs were present in this nascent PLC of teachers. The teachers created their own shared vision and provided evidence of collective learning in the weekly meetings. Participants developed trust and shared many personal practices and experiences of teaching. Challenges to initiating a professional learning community included finding time to meet, a weak school culture, and barriers associated with immigration status. Despite the challenges, there were many perceived benefits, including saving time through subject integration, personalizing professional development, and increasing socialization to reduce teachers' sense of professional isolation. The teachers also displayed changes in attitudes towards teaching and how they approached teaching their classes. Classes became more student-centred as teachers tried to meet the diverse needs of their students. The promise of increased collaboration and membership at the conclusion of data collection failed to materialize when a new leader did not come forward.; Thesis (Ph.D...

A number of puzzles exist regarding the role of domestic politics in the likelihood of international conflict. In particular, the sources of incomplete information remain under-theorized and the microfoundations deficient. This study will examine the role that the unity of the government and the views of the government towards the use of force play in the targeting of states. The theory presented argues that divided dovish governments are particularly likely to suffer from military challenges. In particular, divided governments have difficulty signaling their intentions, taking decisive action, and may appear weak. The theory will be tested on a new dataset created by the author that examines the theory in the context of international territorial disputes. A number of significant findings emerge from the data. First, divided governments are significantly more likely to face challenges and increasing government unity markedly decreases the likelihood of a challenge. Second, unified hawkish governments were far less likely to be the targets of challenges than divided dovish governments. Finally, the substantive impact of key variables was much greater than that of the control variables. The causal process postulated in the theory is examined in eight case studies...

The National Ocean Policy represents recent efforts by the United States federal government to develop a comprehensive plan to manage uses in the federal exclusive economic zone of the ocean. Planning efforts encounter numerous challenges, including: planning long-term action in a system with short-term political cycles, incorporating the uncertainties science in the planning process, and having adequate capacity to manage the problem. Large planning initiatives have additional issues with multi-jurisdictional planning and the need for representative planning bodies. Additionally, the history of the environmental movement in the United States and the history of environmental policies effect the development of the National Ocean Policy. The public comments represent the views of concerned stakeholders and reveal the challenges of this type of planning. A thematic analysis of recent public comments to the Strategic Action Plans for the National Ocean Policy shows that new or additional regulations and fear of negative economic impacts are the primary reasons given by stakeholders opposed to the policy. The reasons given for support of the policy include general environmental protection and the policy as a method to deal with the impacts of climate change. The comments also reveal broader challenges to the planning efforts including the timescale mis-match between policy-making and elections...

This capstone project addresses the problem of sustainability of NGOs in Kosova as the vast majority of NGOs face serious difficulties in sustaining their work. Except for a small number of Kosova NGOs, that managed to achieve a desirable level of institutional and financial sustainability, the rest tend to be failing. According to the numbers provided by the NGO Registration and Liaison Office of the Government of Kosova, out of the around 5000 registered NGOs, about 10% are estimated to be still active or partially active.1 The research methodology of this capstone project was quantitative and qualitative based on surveys and interviews. While, comparative case studies from countries which went through transitional periods was analyzed and presented in order to give a comparative and analytical approach to the issues. This capstone project concentrates on two groups of important factors which affect the NGOs sustainability. The primary group involves 3 main factors: 1) financial, 2) organizational viability and 3) legal. The secondary group involves other four factors: 4) program effectiveness, 5) human capacity, 6) networking and 7) long-term impact on society. This capstone project makes recommendations on how to overcome the difficulties and challenges regarding NGOs’ sustainability. In order to evaluate these seven factors there was conducted a survey with 50 NGOs. This survey contains two questionnaires...

Obesity is the main nutritional problem and one of the most important health problems in developed societies. Central to the challenge of obesity prevention and management is a thoroughly understanding of its determinants. Multiple socio-cultural, socio-economic, behavioural and biological factors -often interrelated and many of them still unknown or poorly understood- can contribute to the establishment and perpetuation of obese phenotypes. Here, we address current research challenges regarding basic aspects of obesity and emerging science for its control, including brown adipose tissue thermogenesis and browning of white fat as possible therapeutic targets for obesity, the influence of the microbioma, and genetics, epigenetics, nutrigenomics and nutrigenetics of obesity. We also highlight hot topics in relation to food and lifestyle as determinants of obesity, including the brain mechanisms underlying environmental motivation to eat, the biological control of spontaneous physical activity, the possible role of concrete foods and food components, and the importance of early life nutrition and environment. Challenges regarding the connections of obesity with other alterations and pathologies are also briefly addressed, as well as social and economical challenges in relation to healthy food production and lifestyle for the prevention of obesity...

Much has been written about orphans and vulnerable children (OVC) with regard to their education and living. However, relatively few studies have documented the psychosocial support provided for OVC in public primary schools to enhance their psychosocial well-being. This study therefore contributes to the understanding of the challenges experienced by teachers in providing psychosocial support for OVC and the possible intervention strategies that could be adopted to mitigate these challenges. Seven public primary schools from Soweto participated in the study, comprising 42 educators and 65 OVC in Grade Seven. Findings that emerged provide supporting evidence that minimal psychosocial support is offered, and it is marred by numerous challenges in public primary schools, including lack of professionals to provide guidance and counselling services, few teachers trained in life orientation, and a lack of support from parents/guardians for OVC. Based on the findings, several intervention strategies are presented.

High expectations are set for Business Intelligence (BI), yet it fails to consistently deliver accordingly: there are numerous reports of BI challenges and failures. Existing approaches to address BI challenges are largely found to be ineffective, highlighting the need for a new approach. This paper examines how BI is perceived or understood and establishes that, firstly, BI is inherently grounded in Goods-Dominant (G-D) logic and secondly, that this can be linked to the challenges that are experienced within BI. A recommendation is made for a shift to Service-Dominant (S-D) logic as a new avenue of exploration to assist in overcoming BI's prevailing challenges. Identifying the inherent G-D logic in BI provides the first step necessary in making this shift. Research findings are based on an interpretive case study of a South African Banking institution as well as a literature review.
