Follow-the-Sun Software Development : Controlled Experiment

Pamulapati, Saroj, Gaddipati, Divya January 2011 (has links)
Context: Global software development (GSD) can be defined as distributing the software development work among various teams, which are geographically distributed. Global software development is being widely used nowadays in software industries because of the numerous advantages offered. Follow-the-sun (FTS) approach is a sub-division of global software engineering where unfinished work is handed off every day from one development site to another development site, which are many time zones apart and hence development takes place round the clock instead of just eight hours per day. Objectives: The objective of this study is to explore whether by implementing follow-the- sun approach in the development phase of the software life cycle, the time-to-market can be reduced by 50% when compared to the traditional method of software development. Methods: In this research to fulfil the objectives, systematic literature review and an experiment were conducted. In literature review a number of papers that are related to this study were identified from the databases such as Engineering Village, IEEE Xplore, Springer Link, ISI Web of Knowledge, Science Direct, ACM Digital Library and Wiley Inter Science Journal Finder. From these databases, all the related work on follow-the-sun approach that has been done so far was collected and the selection was done through tollgate approach. An experiment was conducted at Blekinge Tekniska Högskola with the students of the computer science engineering field as subjects of the experiment. The three software development scenarios that are tested in the experiment are co-located scenario, follow-the-sun with overlap scenario and follow-the-sun without overlap scenario. The experiment compares the results of the co-located scenario with the results of the follow-the-sun with overlap scenario and follow-the-sun without overlap scenario. Results: The results from the experiment showed that there is reduction in time-to-market by 22% when using follow-the-sun with overlap scenario and there is a reduction of 10% in the time-to-market when using follow-the-sun without scenario when compared to the co- located scenario. Conclusions: We conclude that follow-the-sun approach has an advantage of reduction in time-to-market when compared to the traditional co-located approach. But more research needs to be done in finding out the challenges and their mitigation strategies that will be beneficial for the organizations in order to adopt this process. From the findings of the literature review we have observed that due to the communication and collaboration problems, organizations are finding it difficult to achieve the desired benefits from the follow-the-sun approach. As a part of this study we conducted an experiment and we report the various challenges that have been noticed during the execution. From the experiment results we observe that there is a difference in the results between the theory and the practical implementation. We conclude that though the time-to-market can be certainly reduced when using follow-the-sun approach, but the reduction in the development time by 50% is questionable. This may be achieved by emphasizing on the challenges and by mitigating the same thereby bringing it closer to 50%. / Bakgrund: Global utveckling av programvara (GSD) kan definieras som distribuerar programvaran utvecklingsarbetet mellan olika team, som är geografiskt fördelade. Global mjukvaruutveckling är i stor utsträckning används i dag inom programvaruföretag på grund av många fördelar. Follow-the-sun (FTS) tillvägagångssätt är en underavdelning av den globala programvaruteknik där halvfärdiga arbeten delas ut varje dag från en utveckling plats till en annan utveckling webbplats, som är många tidzoner isär och därigenom utveckling sker dygnet runt istället för att bara åtta timmar per dag. Syfte: Syftet med denna studie är att undersöka om genom att implementera follow-the- Sön förhållningssätt i utvecklingsfasen av programvaran livscykel, tiden till marknaden kan reduceras med 50% jämfört med den traditionella metoden för mjukvaruutveckling. Metoder: I denna forskning för att uppfylla de mål, systematisk litteraturstudie och en Experimentet utfördes. I litteraturen ett antal uppsatser som är relaterade till denna studien identifierades från databaser såsom Engineering Village, IEEE Xplore, Springer Link, ISI Web of Knowledge, Science Direct, ACM Digital Library och Wiley Inter Science Journal Finder. Från dessa databaser, alla relaterade arbetet efter-the-sun strategi som har gjort hittills har samlats in och urvalet gjordes genom tollgate strategi. En Experimentet utfördes på Blekinge Tekniska Högskola med eleverna av datorn vetenskap teknikområde som ämnen av försöket. De tre mjukvaruutveckling scenarier som testas i experimentet är samlokaliserade scenariot, follow-the-solen med överlappning scenario och follow-the-solen utan överlappning scenario. Experimentet jämför Resultatet av samarbetet ligger-scenario med resultaten av follow-the-solen med överlappning scenario och följ-the-solen utan överlappning scenario. Resultat: Resultatet från experimentet visade att det finns minskning av tiden till marknaden genom 22% vid användning av follow-the-solen med överlappning scenario och det är en minskning med 10% i time-to-market när du använder follow-the-solen utan scenario jämfört med co- ligger scenario. Slutsatser: Vi drar slutsatsen att följa the-sun metoden har en fördel av minskning av time-to-market jämfört med traditionella samlokaliserade strategi. Men mer forskning behöver göras för att hitta de utmaningar och deras strategier för riskminskning som kommer att fördelaktigt för organisationer för att anta denna process. Från resultaten av litteraturstudie har vi sett att på grund av kommunikation och samarbete problem, organisationer svårt att uppnå önskad nytta av follow-the-sun strategi. Som en del av denna studie har vi genomfört ett experiment och vi rapporterar de olika utmaningar som har märkt under utförandet. Från experimentet resultat vi konstatera att det finns en skillnad i resultat mellan teori och praktiska genomförandet. Vi drar slutsatsen att även om tiden till marknad kan säkert nedsatt vid användning följ-the-sun synsätt, men minskningen av utvecklingstiden genom 50% är tvivelaktig. Detta kan uppnås genom att betona på de utmaningar och genom att mildra samma sätt föra den närmare 50%.

Short-to-Medium Term Enrollment Projection Based on Cycle Regression Analysis

Chizari, Mohammad 08 1900 (has links)
Short-to-medium projections were made of student semester credit hour enrollments for North Texas State University and the Texas Public and Senior Colleges and Universities (as defined by the Coordinating Board, Texas College and University System). Undergraduate, Graduate, Doctorate, Total, Education, Liberal Arts, and Business enrollments were projected. Fall + Spring, Fall, Summer I + Summer II, Summer I were time periods for which projections were made. A new regression analysis called "cycle regression" which employs nonlinear regression techniques to extract multifrequential phenomena from time-series data was employed for the analysis of the enrollment data. The heuristic steps employed in cycle regression analysis are similar to those used in fitting polynomial models. A trend line and one or more sin waves (cycles) are simultaneously estimated using a partial F test. The process of adding cycle(s) to the model continues until no more significant terms can be estimated.

Ce que l'information en continu fait à l'information. Le cas de BFMTV / What Continuous Information does to Information. The Exemple of BFMTV

Jeandot, Chrystel 09 December 2016 (has links)
Si l’information en continu semble constituer un genre télévisuel aujourd’hui installé, le modèle d’information qu’elle propose fait l’objet de nombreuses questions concernant les effets de reprise de l’information et la nature même de celle-ci. Parce que la chaîne BFMTV cristallise ces questions critiques, il a semblé pertinent, au moment où elle a plus de dix ans d’existence, d’essayer de comprendre le type d’information dont il s’agit. D’autant qu’elle se présente dorénavant, dans un contexte de convergence médiatique, sur plusieurs supports évoluant au gré des pratiques et des possibilités techniques, qui poussent à se pencher sur le lien que la chaîne, via son dispositif, entretient avec ses usagers. Pensé selon une approche pragmatique, ce travail a ainsi pour ambition de mieux cerner les enjeux de l’information en continu mais aussi ses impacts sur l’information en général. / If 24-hour news channels today seem to constitute an established television genre, the type of information that they provide leaves many questions open concerning both the re-presentation of information and the latter’s very nature. Because the 24-hour news channel BFMTV incarnates those critical questions, it seems relevant, more than ten years after its creation, to examine the model of information that it provides. Moreover, in the context of media convergence, this channel is now transmitted on several platforms that evolve according to the user's practices and existing technical possibilities. This fact leads to a further examination of how the channel develops a relationship, through its technical possibilities, with its users. Deploying a pragmatic approach, this thesis aims to achieve a better understanding of what is at stake in continuous news cycles and also of the impact that the latter have on information in general.

Examining the Impact of Canadian Political Satire Shows on Generation Y: A Qualitative Investigation of This Hour Has 22 Minutes

Attalla, Jessica January 2015 (has links)
In contemporary society, political satire shows are prominent programs that seem to resonate with the viewing public. This thesis seeks to observe the meanings that generation Y attach to the Canadian political satire show, This Hour Has 22 Minutes. Focusing on the Canadian context, this research examines how members of generation Y view political satire shows, specifically This Hour Has 22 Minutes and if this show caters to their attitudes, concerns and interests more so than traditional news media. The theoretical framework guiding this study is the uses and gratifications theory. This research implements a qualitative phenomenological research approach in the form of focus groups. This study concludes that this generation still maintains, however, that when looking to be informed, they connect more with traditional news media given that these programs provide them with all the facts and stories in a more reliable manner. This study contributes to the field of communication because it demonstrates the rationale and experiences of generation Y in relation to political news.

Effect of an Aerobic Exercise Program on Daily Energy Expenditure and Intake in Adolescents.

Biagé, Alyssa January 2016 (has links)
Objectives: The purpose of this study was to investigate the effect of an 8-week aerobic exercise program on daily energy expenditure and intake in adolescents with normal-weight and with overweight or obesity. Methods: Prospective intervention study. The study included twenty-six adolescents aged between 14-18 years: 17 adolescents (8 girls and 9 boys) with normal-weight (BMI <85th percentiles for age and sex), and 9 adolescents (5 girls and 4 boys) with overweight or obesity (BMI 85th percentile for age and sex). The aerobic exercise program included 30 minutes of cycling performed on a Monark cycle ergometer 3 times a week for 8 weeks at an exercise target heart rate at 75% of participants’ heart rate reserve using the Karvonen formula. Total daily energy expenditure was measured with an indirect calorimeter wear for resting metabolic rate and a 7-day accelerometer for energy expenditure from physical activity. Energy intake was estimated with 24-hour recalls. Results: The aerobic exercise program did not have any significant effect on body weight. Significant effects of aerobic exercise on total daily energy expenditure (p=.051), energy expenditure from physical activity (p=.031) and total daily energy intake (p=.008) were observed, which mainly revealed a reduction in daily physical activity and energy intake following the exercise program. However, there was no significant effect of weight status and no interaction effect between of aerobic exercise and weight status for those three variables. Conclusions: Adolescents with normal weight, overweight or obesity not only reduced their daily total energy expenditure by reducing physical activity, but simultaneously decreased their total daily energy intake after an aerobic exercise program.

WWF's Earth Hour Campaign: ‘Global Village' or Eco-Imperialism?

Chao, Eileen 10 September 2020 (has links)
The rapid spread of digital information and communication technologies since the turn of the century has led to renewed debates about globalisation and the power of new media to connect users across national, political and cultural borders. Environmental campaigns like WWF's Earth Hour, which touts itself as “the world's largest grassroots movement for the environment,” often adopt a utopian view of globalisation that celebrates what Marshall McLuhan termed the ‘global village'. While this global ethos might be useful in engaging the publics in collective action, this article argues that the way Earth Hour and similar campaigns actively construct representations of a single global village overlooks the lived inequalities between and among peoples within this imagined community. This article explores this tension using a quantitative and qualitative mixed-methods approach that combines a semiotic analysis of the Earth Hour 2019 promotional video, social media analysis of the use of #Connect2Earth hashtag among South African Twitter users, and in-depth interviews with current and former WWF-South Africa employees. This strategic approach is designed to juxtapose socially constructed representations of Earth Hour with on-the-ground user engagement in South Africa, and then triangulating these findings with qualitative interviews. The dissertation aims to explore the research question: In what ways does WWF's Earth Hour embody Marshall McLuhan's ideal ‘global village' and in what ways might it engender a form of eco-imperialism? This research question is operationalised through three subquestions: What kind of environmentalism do global environmental campaigns like Earth Hour promote? How do audiences in South Africa engage with Earth Hour on social media? How do local WWF of ices adapt global environmental campaigns to suit local audiences? This research contributes to emerging scholarship, rooted in environmental justice and decolonial studies, that is critical of mainstream environmental movements not to discourage environmental consciousness but to ultimately reformulate it.

Stomach Capacity, Digestion Rate, and 24-Hour Consumption Rate for the Bear Lake Sculpin (Cottus Extensus)

Williamson, Joseph H. 01 May 1970 (has links)
A curvilinear regression model was used to determine an expected stomach capacity for any size Bear Lake sculpin with a standard length between 4-9.5 centimeters. Stomach contents were then expressed as a percent fullness and the change in percent fullness with time intervals was used to compute an instantaneous digestion rate. The instantaneous consumption rate was computed by the formula C=log P1-log P0 +d, where C=instantaneous consumption rate. The amount of food consumed during a time interval was computed from the formula It=CtSt, where It=amount of food ingested during a time interval expressed in percent fullness of stomach. The 24 hour consumption rate was computed by summing the consumption rates for 4 consecutive time intervals of 6 hours each. Studies in September, December, and May give instantaneous digestion rates of -.424, -.214, and -.235 and total food consumption rates of 22.2, 10.2, and 6.1 percent of stomach capacity for each individual fish in the population.

24 Hour Portraits

Cowan, Lee R. 16 July 2010 (has links) (PDF)
I believe an individual can be profiled by their color preferences, but not indefinitely, for a shorter period of time, a 24-hour period of time. A person's state of mind will change continually based on their experiences. These experiences will affect their perception and preference of color. I developed a model that will map an individual's profile, a portrait, through color. Participants are given a worksheet and a list of terms describing personality traits and states of mind. The worksheet is categorized by event, time of day, duration, impact, and summed term. From midnight to midnight, a 24-hour period, the participant records any event that they encounter providing information-fulfilling categories stated above. I use that information to then map out their portrait of 24-hours through color.

The WOW Factor: Lesbian Representation and Impact in Late-20th Century Theatre

Maginness, Brenna L 01 January 2019 (has links)
The intent of this thesis is to investigate the influence of 1980's and 1990's lesbian playwrights on modern queer representation in theatre. By analyzing the successful works of troupes and artists born out of the Women's One World (WOW) Café, it became apparent that the greatest changes in lesbian portrayal on stage came from queer and feminist authorship. Additionally, WOW Café became the common denominator in the success of many lesbian playwrights due to the freedom it gave its writers and performers. As an independent theatre, WOW allowed its members to experiment with few rules, and offered a stage to pieces too experimental, feminist, or queer to see commercial Broadway success. Thesis discussion includes analysis of historically homophobic theatre, the techniques and topics conveyed in the work of The Five Lesbian Brothers and Split Britches, and the importance of WOW as a stepping stone for the success of plays like Lisa Kron's Well. Lesbian-centric work is often left out of theatre history in classrooms even today, and by diving deeper into the important history of queer women in drama, the intent of this thesis is to add to the academia in a way that helps future lesbian artists, performers, and students recognize themselves in the narrative.
