Evaluating the Success of Lodging Yield Management Systems

Although there are more than 7,000 properties using lodging yield management systems (LYMSs), both practitioners and researchers alike have found it difficult to measure their success. Considerable research was performed in the 1980s to develop success measures for information systems in general. In this work the author develops success measures specifically for LYMSs.

Variables affecting the success of older applicants for employment in a public organization: An age -cued cognitive model of administrative decision-making

The dissertation takes a multivariate approach to answer the question of how applicant age, after controlling for other variables, affects employment success in a public organization. In addition to applicant age, there are five other categories of variables examined: organization/applicant variables describing the relationship of the applicant to the organization; organization/position variables describing the target position as it relates to the organization; episodic variables such as applicant age relative to the ages of competing applicants; economic variables relating to the salary needs of older applicants; and cognitive variables that may affect the decision maker's evaluation of the applicant. ^ An exploratory phase of research employs archival data from approximately 500 decisions made in the past three years to hire or promote applicants for positions in one public health administration organization. A logit regression model is employed to examine the probability that the variables modify the effect of applicant age on employment success. A confirmatory phase of the dissertation is a controlled experiment in which hiring decision makers from the same public organization perform a simulated hiring decision exercise to evaluate hypothetical applicants of similar qualifications but of different ages. The responses of the decision makers to a series of bipolar adjective scales add support to the cognitive component of the theoretical model of the hiring decision. A final section contains information gathered from interviews with key informants. ^ Applicant age has tended to have a curvilinear relationship with employment success. For some positions, the mean age of the applicants most likely to succeed varies with the values of the five groups of moderating variables. The research contributes not only to the practice of public personnel administration, but is useful in examining larger public policy issues associated with an aging workforce. ^

A comparison study of the English III/American Literature success of African American high school students and that of students whose home language is Haitian Creole

The purpose of the study was to compare the English III success of students whose home language is Haitian Creole (SWHLIHC) with that of the more visible African American high school students in the Miami Dade County Public Schools System, in an effort to offer insight that might assist educators in facilitating the educational success of SWHLIHC in American Literature class.^ The study was guided by two important theories on how students interact with and learn from literature. They are Reader Response Theory which advocates giving students the opportunity to become involved in the literature experience (Rosenblatt, 1995), and Critical Literacy, a theory developed by Paolo Freire and Henry Giroux, which espouses a critical approach to analysis of society that enables people to analyze social problems through lenses that would reveal social inequities and assist in transforming society into a more equitable entity.^ Data for the study: 10th grade reading FCAT scores, English III/American Literature grades, and Promotion to English IV records for the school year 2010-2011 were retrieved from the records division of the Miami Dade County Public Schools System. The study used a quantitative methods approach, the central feature of which was an ex post facto design with hypotheses (Newman, Newman, Brown, & McNeely, 2006). The ex post facto design with hypotheses was chosen because the researcher postulated hypotheses about the relationships that might exist between the performances of SWHLIHC and those of African American students on the three above mentioned variables. This type of design supported the researcher's purpose of comparing these performances.^ One way analysis of variance (ANOVA), two way ANOVAs, and chi square tests were used to examine the two groups' performances on the 10th grade reading FCAT, their English III grades, and their promotion to English IV. ^ The study findings show that there was a significant difference in the performance of SWHLIHC and African American high school students on all three independent variables. SWHLIHC performed significantly higher on English III success and promotion to English IV. African American high school students performed significantly higher on the reading FCAT.^

Seawater carbonate chemistry and sperm swimming speed, fertilization success of the Australasian sea urchin Heliocidaris erythrogramma in lab experiment

Background: Climate change will lead to intense selection on many organisms, particularly during susceptible early life stages. To date, most studies on the likely biotic effects of climate change have focused on the mean responses of pooled groups of animals. Consequently, the extent to which inter-individual variation mediates different selection responses has not been tested. Investigating this variation is important, since some individuals may be preadapted to future climate scenarios. Methodology/Principal Findings: We examined the effect of CO2-induced pH changes ("ocean acidification") in sperm swimming behaviour on the fertilization success of the Australasian sea urchin Heliocidaris erythrogramma, focusing on the responses of separate individuals and pairs. Acidification significantly decreased the proportion of motile sperm but had no effect on sperm swimming speed. Subsequent fertilization experiments showed strong inter-individual variation in responses to ocean acidification, ranging from a 44% decrease to a 14% increase in fertilization success. This was partly explained by the significant relationship between decreases in percent sperm motility and fertilization success at delta pH = 0.3, but not at delta pH = 0.5. Conclusions and Significance: The effects of ocean acidification on reproductive success varied markedly between individuals. Our results suggest that some individuals will exhibit enhanced fertilization success in acidified oceans, supporting the concept of 'winners' and 'losers' of climate change at an individual level. If these differences are heritable it is likely that ocean acidification will lead to selection against susceptible phenotypes as well as to rapid fixation of alleles that allow reproduction under more acidic conditions. This selection may ameliorate the biotic effects of climate change if taxa have sufficient extant genetic variation upon which selection can act.

Exploring the Success of Student Experiential Learning through Entrepreneurial Opportunities

Academic literature has increasingly recognized the value of non-traditional higher education learning environments that emphasize action-orientated experiential learning for the study of entrepreneurship (Gibb, 2002; Jones & English, 2004). Many entrepreneurship educators have accordingly adopted approaches based on Kolb’s (1984) experiential learning cycle to develop a dynamic, holistic model of an experience-based learning process. Jones and Iredale (2010) suggested that entrepreneurship education requires experiential learning styles and creative problem solving to effectively engage students. Support has also been expressed for learning-by-doing activities in group or network contexts (Rasmussen and Sorheim, 2006), and for student-led approaches (Fiet, 2001). This study will build on previous works by exploring the use of experiential learning in an applied setting to develop entrepreneurial attitudes and traits in students. Based on the above literature, a British higher education institution (HEI) implemented a new, entrepreneurially-focused curriculum during the 2013/14 academic year designed to support and develop students’ entrepreneurial attitudes and intentions. The approach actively involved students in small scale entrepreneurship activities by providing scaffolded opportunities for students to design and enact their own entrepreneurial concepts. Students were provided with the necessary resources and training to run small entrepreneurial ventures in three different working environments. During the course of the year, three applied entrepreneurial opportunities were provided for students, increasing in complexity, length, and profitability as the year progressed. For the first undertaking, the class was divided into small groups, and each group was given a time slot and venue to run a pop-up shop in a busy commercial shopping centre. Each group of students was supported by lectures and dedicated class time for group work, while receiving a set of objectives and recommended resources. For the second venture, groups of students were given the opportunity to utilize an on-campus bar/club for an evening and were asked to organize and run a profitable event, acting as an outside promoter. Students were supported with lectures and seminars, and groups were given a £250 budget to develop, plan, and market their unique event. The final event was optional and required initiative on the part of the students. Students were given the opportunity to develop and put forward business plans to be judged by the HEI and the supporting organizations, which selected the winning plan. The authors of the winning business plan received a £2000 budget and a six-week lease to a commercial retail unit within a shopping centre to run their business. Students received additional academic support upon request from the instructor, and one of the supporting organizations provided a training course offering advice on creating a budget and a business plan. Data from students taking part in each of the events was collected, in order to ascertain the learning benefits of the experiential learning, along with the successes and difficulties they faced. These responses have been collected and analyzed and will be presented at the conference along with the instructor’s conclusions and recommendations for the use of such programs in higher educations.

Influence of Food Distribution and Human Disturbance on the Reproductive Success of Herring Gulls

A three year study of Herring Gull (Larus argentatus) reproductive success on four i~lands in Maine indicate.d that production of young was controlled by different factors operating on the eggs and chicks. Hatching success was inversely related to the disturbance of co.Ionics by pic~i~kers, which apparently caused the adults to leave their eggs exposed 10 sufficient solar rad1a11on to addle the eggs. The survival of chicks was lower on islands distant ~rom sources of edible r~~use (ou.ter. islands) than o.n. islands close to sources of waste (inner islands), regardless of visits by picnickers. The nutrition and growth rates of chicks on inner and outer islands were similar. The attendance of parents on the territories was found to be less o~ an out~r islan~ than on an inner island. It is concluded that differences in parental behavior associated with greater foraging effort were responsible for a higher loss of chicks to predation on the outer islands.

Nokia- The surprising success of textbook wisdom

What is the secret behind Nokia’s phenomenal success in mobile phones? More generally, how to succeed in a turbulent high technology market? Historical and comparative studies bring understanding not only about past phenomena, but also insights about current and coming ones. In this paper we compare Ford and General Motors in the 1920s and 1930s with Motorola and Nokia in the 1980s and 1990s. The insight from this comparison is how reinvention of the product, category, relative to the market incumbent’s market conceptualization, is a recipe for success. Nokia’s success in the 1990s was based on following the guidelines pioneered by General Motors in the 1920s: market segmentation, embracing the latest technological advances, and brand management in the pursuit of consumer repurchases. The article tells how Nokia addresses both GM’s legacy and changes in the business environment. At the end of our paper, we disuss the generalizability of our findings.

VERIFYING SUCCESS OF ARTIFICIAL REEFS IN THE HURON-ERIE CORRIDOR FOR LAKE STURGEON

Lake sturgeon (Acipenser fulvescens) were historically abundant in the Huron-Erie Corridor (HEC), a 160 km river/channel network composed of the St. Clair River, Lake St. Clair, and the Detroit River that connects Lake Huron to Lake Erie. In the HEC, most natural lake sturgeon spawning substrates have been eliminated or degraded as a result of channelization and dredging. To address significant habitat loss in HEC, multi-agency restoration efforts are underway to restore spawning substrate by constructing artificial spawning reefs. The main objective of this study was to conduct post-construction monitoring of lake sturgeon egg deposition and larval emergence near two of these artificial reef projects; Fighting Island Reef in the Detroit River, and Middle Channel Spawning Reef in the lower St. Clair River. We also investigated seasonal and nightly timing of larval emergence, growth, and vertical distribution in the water column at these sites, and an additional site in the St. Clair River where lake sturgeon are known to spawn on a bed of ~100 year old coal clinkers. From 2010-12, we collected viable eggs and larvae at all three sites indicating that these artificial reefs are creating conditions suitable for egg deposition, fertilization, incubation, and larval emergence. The construction methods and materials, and physical site conditions present in HEC artificial reef projects can be used to inform future spawning habitat restoration or enhancement efforts. The results from this study have also identified the likelihood of additional uncharacterized natural spawning sites in the St. Clair River. In addition to the field study, we conducted a laboratory experiment involving actual substrate materials that have been used in artificial reef construction in this system. Although coal clinkers are chemically inert, some trace elements can be reincorporated with the clinker material during the combustion process. Since lake sturgeon eggs and larvae are developing in close proximity to this material, it is important to measure the concentration of potentially toxic trace elements. This study focused on arsenic, which occurs naturally in coal and can be toxic to fishes. Total arsenic concentration was measured in samples taken from four substrate treatments submerged in distilled water; limestone cobble, rinsed limestone cobble, coal clinker, and rinsed coal clinker. Samples were taken at three time intervals: 24 hours, 11 days, and 21 days. ICP-MS analysis showed that concentrations of total arsenic were below the EPA drinking water standard (10 ppb) for all samples. However, at the 24 hour sampling interval, a two way repeated measures ANOVA with a Holm-Sidak post hoc analysis (α= 0.05) showed that the mean arsenic concentration was significantly higher in the coal clinker substrate treatment then in the rinsed coal clinker treatment (p=0.006), the limestone cobble treatment (p

Leadership in the mobile smartphone market

The mobile telecommunications industry has been going through an enormous revolution, especially after mid-1990 when smartphones were introduced to the market. As a consequence, the smartphone market’s dynamism is requesting companies to operate differently in the way they do business. After a long period occupying the leader position in the smartphones manufacturers’ rank, Nokia was outperformed by Apple and Samsung during 2011 and since then has been on the third place. Nevertheless, Nokia is battling for regaining the leadership in such a competitive and high-velocity growing market and that is what this research is about. This research covers the competitive and strategic forces that shape dynamic industries whereas the main purpose is to elucidate the main factors that contribute to a company’s above-average performance and ultimately determine its leadership in the mobile smartphone market. Therefore, this exploratory qualitative research was conducted as a desk research, which utilized various secondary sources of data in the knowledge area of strategic management such as theories about competitive advantages and dynamic capabilities of firms, innovation, and strategy. This research is enriched with a case study about Nokia: how the company has been organizing its corporate structure to support the strategies and hence how it has been competing in the smartphone market is analyzed, taking into account many contemporary data sources, including market analysts’ and business experts’ opinions. As a result of the classic literature exploration and the case study assay, a framework for deeper analysis of the competitiveness of firms in dynamic markets was developed. The conclusion that emerged from this research is that the success of a firm results from the interplay of various factors. To regain the leader position in the mobile smartphone market is a challenging task that requires Nokia to reinvent its core strategy for taking charge of the smartphones’ industry transformation through for example the adoption of the open innovation concept. It is imperative that Nokia designs and implement a breakthrough strategy as well as embraces the uncertainty of the smartphone market competition as an opportunity for discontinuous innovation development with the ultimate goal of recovering the leadership.

Perhe yrityksen dominanttina omistajana: hyödyt yritykselle ja vähemmistöosakkaille

Pro gradu -tutkielman tavoitteena on ollut tutkia millaisia hyötyjä perheestä voi olla omistamalleen yritykselle ja sen vähemmistöosakkaille. Tutkielman kontekstina ovat perheyritykset ja erityisesti perheen kokemus omasta roolistaan omistajana. Tutkimus on toteutettu laadullisena tutkimuksena ja aineistona ovat olleet puolistrukturoidut haastattelut suomalaisissa listatuissa perheyhtiöissä. Tutkimuksen tuloksina voidaan osoittaa, että perheen vaikutus yrityksen menestymiseen on monitahoinen ja perheenjäsenet pyrkivät toimimaan pitkäjänteisesti yhteisen hyvän eteen. Tästä on hyötyä yritykselle ja sen vähemmistöosakkaille pitkällä aikajänteellä.

Omistajuuden vaikutus yrityksen toimintaan ja tulokseen

Tämän tutkimuksen tavoitteena oli selvittää miten omistajuus vaikuttaa yrityksen toimintaan ja tulokseen ja syventää näkökulmaa omistajan vaikutuksesta yrityksen menestymiseen. Tutkimus tehtiin kvalitatiivisen ja kvantitatiivisen tutkimusmenetelmän yhdistelmällä, joka mahdollistaa laajemman näkökulman tutkittavaan asiaan ja tuo tutkimukseen luotettavuutta. Omistajan kompetenssilla toimia aktiivisena omistajana sekä hallita erilaisia liiketoimintariske-jä on suuri merkitys. Kestävä menestys, uudistuminen ja yrityksen arvon luominen vaativat niin asiantuntemusta, näkemyksiä, sitoutunutta riskirahoitusta kuin vuorovaikutustaitoja. Omis-tajalla on vaikutusvalta osaavan johdon ja henkilöstön motivaation ylläpysymiseen ja tahtoti-laan toimia yrityksen etujen mukaisesti ja yritykseen sitoutuneena. Ymmärtämällä omistamansa yrityksen kilpailuedut ja hallitsemalla organisatoriset riskit, omis-taja voi vaikuttaa valitsemansa roolin kautta yrityksen menestykseen ja tuottoarvon kasvuun. Tutkimuksen tulokset viittaavat myös siihen, että henkilöstön kokemat positiiviset psykologi-sen ja sosiaalisen omistajuuden tunteet selittävät onnistumisia.
