Organizational Effectiveness Along Life-Cycle Stages: A Comparison Of Wendy's And McDonald's

"Perceptions of Organizational Effectiveness over Organizational Life Cycles" written by Kim S. Cameron and David S. Whetten, posits a theory regarding organizational effectiveness criteria change as firms develop along the life cycle continuum. Induced from observations obtained from a simulation game, the Cameron and Whetten theory is applied in this article to two real organizations, Wendy's and McDonald's, with the intention of demonstrating that this theory is applicable in "real life" situations.

An evaluation of depression, self-efficacy, satisfaction with life and perceived access to medical care across stages of HIV infection

This survey was designed to identify the incidence and scope of depression, satisfaction with life, self-efficacy and perceived access to medical care for those who are infected with the HIV virus. It also determined whether or not factors such as sexual orientation, ethnicity and socioeconomic status are intervening variables with respect to mental health issues. Subjects were recruited through a purposive sample from South Florida. A total of 871 surveys were used in the analysis. The overall response rate was nearly 90%. The incidence of depression was found to be higher than 75% across all stages of HIV infection. Furthermore, the incidence of depression increased as HIV disease progressed. Satisfaction with life and for the most part, self efficacy were found to decrease slightly as HIV disease progressed. Significant variance in depression, life satisfaction and self efficacy were found across stages of HIV infection. No significant differences between groups that were HIV infected were found for depression, life satisfaction and self efficacy. The severity of depression was found to vary significantly with self efficacy, life satisfaction and access to medical care but not with socioeconomic status. Life satisfaction was found to vary significantly with socioeconomic status, depression and self efficacy but not with access to medical care. Self-efficacy was found to vary significantly with socioeconomic status, depression and life satisfaction but not with access to medical care. Gender and ethnicity were not found to be significant precedent variables in depression for HIV infected individuals. Sexual orientation was found to be a significant precedent variable for depression, life satisfaction and self efficacy.

Seawater carbonate chemistry and biological processes during experiments with early life stages of the blue mussel Mytilus edulis, 2010

Several experiments have shown a decrease of growth and calcification of organisms at decreased pH levels. There is a growing interest to focus on early life stages that are believed to be more sensitive to environmental disturbances such as hypercapnia. Here, we present experimental data, acquired in a commercial hatchery, demonstrating that the growth of planktonic mussel (Mytilus edulis) larvae is significantly affected by a decrease of pH to a level expected for the end of the century. Even though there was no significant effect of a 0.25-0.34 pH unit decrease on hatching and mortality rates during the first 2 days of development nor during the following 13-day period prior to settlement, final shells were respectively 4.5±1.3 and 6.0±2.3% smaller at pHNBS~7.8 (pCO2~1100-1200 µatm) than at a control pHNBS of ~8.1 (pCO2~460-640 µatm). Moreover, a decrease of 12.0±5.4% of shell thickness was observed after 15d of development. More severe impacts were found with a decrease of ~0.5 pHNBS unit during the first 2 days of development which could be attributed to a decrease of calcification due to a slight undersaturation of seawater with respect to aragonite. Indeed, important effects on both hatching and D-veliger shell growth were found. Hatching rates were 24±4% lower while D-veliger shells were 12.7±0.9% smaller at pHNBS~7.6 (pCO2~1900 µatm) than at a control pHNBS of ~8.1 (pCO2~540 µatm). Although these results show that blue mussel larvae are still able to develop a shell in seawater undersaturated with respect to aragonite, the observed decreases of hatching rates and shell growth could lead to a significant decrease of the settlement success. As the environmental conditions considered in this study do not necessarily reflect the natural conditions experienced by this species at the time of spawning, future studies will need to consider the whole larval cycle (from fertilization to settlement) under environmentally relevant conditions in order to investigate the potential ecological and economical losses of a decrease of this species fitness in the field.

Effects of ocean acidification on embryonic respiration and development of a temperate wrasse living along a natural CO2 gradient

Volcanic CO2 seeps provide opportunities to investigate the effects of ocean acidification on organisms in the wild. To understand the influence of increasing CO2 concentrations on the metabolic rate (oxygen consumption) and the development of ocellated wrasse early life stages, we ran two field experiments, collecting embryos from nesting sites with different partial pressures of CO2 [pCO2; ambient (400 µatm) and high (800-1000 µatm)] and reciprocally transplanting embryos from ambient- to high-CO2 sites for 30 h. Ocellated wrasse offspring brooded in different CO2 conditions had similar responses, but after transplanting portions of nests to the high-CO2 site, embryos from parents that spawned in ambient conditions had higher metabolic rates. Although metabolic phenotypic plasticity may show a positive response to high CO2, it often comes at a cost, in this case as a smaller size at hatching. This can have adverse effects because smaller larvae often exhibit a lower survival in the wild. However, the adverse effects of increased CO2 on metabolism and development did not occur when embryos from the high-CO2 nesting site were exposed to ambient conditions, suggesting that offspring from the high-CO2 nesting site could be resilient to a wider range of pCO2 values than those belonging to the site with present-day pCO2 levels. Our study identifies a crucial need to increase the number of studies dealing with these processes under global change trajectories and to expand these to naturally high-CO2 environments, in order to assess further the adaptive plasticity mechanism that encompasses non-genetic inheritance (epigenetics) through parental exposure and other downstream consequences, such as survival of larvae.

Exploring the stages of change and perceived barriers to treatment models within the context of parental adherence to an early intervention program

Parent-mediated early intervention programs depend on the willingness and ability of parents to complete prescribed activities with their children. In other contexts, internal factors, such as stages of change, and external factors, such as barriers to treatment, have been shown to correlate with adherence to service. This researcher modified the Stages of Change Questionnaire as well as the Barriers to Treatment Participation Scale (BTPS) to use with this population. Despite initial interest, twenty-three parent participants were referred to the researcher over the course of three years, with only five parents taking part in the study. A population base ten times that of the current sample would be required recruit enough participants (fifty-one) to provide sufficient power. This feasibility study discusses the results of the five parent participants. Findings suggest that the modified Stages of Change Questionnaire may not be sensitive enough for use with the current sample, while the modified BTPS may yield useful information for service providers.

Effect of ocean warming and acidification on the early life stages of subtropical Acropora spicifera

This study investigated the impacts of acidified seawater (pCO2 900 µatm) and elevated water temperature (+3 °C) on the early life history stages of Acropora spicifera from the subtropical Houtman Abrolhos Islands (28°S) in Western Australia. Settlement rates were unaffected by high temperature (27 °C, 250 µatm), high pCO2 (24 °C, 900 µatm), or a combination of both high temperature and high pCO2 treatments (27 °C, 900 µatm). There were also no significant differences in rates of post-settlement survival after 4 weeks of exposure between any of the treatments, with survival ranging from 60 to 70 % regardless of treatment. Similarly, calcification, as determined by the skeletal weight of recruits, was unaffected by an increase in water temperature under both ambient and high pCO2 conditions. In contrast, high pCO2 significantly reduced early skeletal development, with mean skeletal weight in the high pCO2 and combined treatments reduced by 60 and 48 %, respectively, compared to control weights. Elevated temperature appeared to have a partially mitigative effect on calcification under high pCO2; however, this effect was not significant. Our results show that rates of settlement, post-settlement survival, and calcification in subtropical corals are relatively resilient to increases in temperature. This is in marked contrast to the sensitivity to temperature reported for the majority of tropical larvae and recruits in the literature. The subtropical corals in this study appear able to withstand an increase in temperature of 3 °C above ambient, indicating that they may have a wider thermal tolerance range and may not be adversely affected by initial increases in water temperature from subtropical 24 to 27 °C. However, the reduction in skeletal weight with high pCO2 indicates that early skeletal formation will be highly vulnerable to the changes in ocean pCO2 expected to occur over the twenty-first century, with implications for their longer-term growth and resilience.

Lithological and chemical composition, stages of sediment accumulation, and sedimentation rates in Core PSh24-2537, West Gotland Basin, Baltic Sea

We studied the grain-size, mineral and chemical compositions, physical properties, radiocarbon age, spore-pollen spectra, and diatom composition in sediments from Core PSh24-2537 sampled in the West Gotland Basin. Four lithological-stratigraphic units were distinguished: varved clays of the Baltic Ice Lake, black and black-gray (sulfide) clays of the Yoldian Sea, gray clays of Ancylus Lake, and greenish-gray sapropel-like littorine and post-littorine silts of the marine stage of Holocene. These units differ from each other both in their matter composition and in plant remains. In the littorine silts organic carbon concentra¬tion reached from 1.5 to 10.35%. Conditions of sediment accumulation and the stages of evolution of the West Gotland Basin over the post-glacial time are characterized.

Averaged sedimentation rates in the Northwest Pacific and Bering Sea during the first and the second oxygen isotope stages

Isotope chronostratigraphy of Upper Quaternary sediments from the Northwest Pacific and the Bering Sea was established by oxygen isotope records in planktonic and benthic foraminifera. The main regularities of temporal variations of calcium carbonate, organic carbon and opal contents, as well as of magnetic susceptibility in sediments of the study region with regard to climatic variations and productivity were established by means of isotopic-geochemical and lithophysical analyses of bottom sediments. Correlation of volcanogenic interbeds in the sediments was carried out, and their stratigraphy and age were preliminarily ascertained. Correlation was accomplished of A.P. Jouse diatom horizons determined by an analysis of the main ecological variations in diatom assemblages in Upper Quaternary sediments of the Northwest Pacific, Bering and Okhotsk Seas, and their comparison with similar variations in sediment cores with standard oxygen isotope stages. Also variations in lithology and contents of biogenic components in sediments of the region and in the cores were taken into account. A ratio of abundance of "neritic" species to the sum of "neritic" and oceanic species abundance (coefficient Id) can be a criterion of ecological changes of diatom assemblages in the studied region. It is determined by climate variability and mostly by sea ice influence. Schemes of average sedimentation rates in the Northwest Pacific and Bering Sea for periods of the first and the second oxygen isotope stages (12.5-1 and 24-12.5 ka, respectively) were plotted on the basis of obtained results and correlation of diatom horizons and lithological units in early studied cores with the oxygen isotope stages. Closure of the Bering Strait and aeration of the north-eastern shelf of the Bering Sea during the second stage induced increase of sedimentation rates in the Bering Sea, as compared with the first stage, and suspended material transport from the Bering Sea through the Kamchatka Strait into the Northwest Pacific and its accumulation in the southeast direction.

Seawater carbonate chemistry and effects of CO2 and their modulation by light in the life-cycle stages of the coccolithophore Emiliania huxleyi strains RCC 1216 and 1217 during experiments, 2012

The effects of ocean acidification on the life-cycle stages of the coccolithophore Emiliania huxleyi and their by light were examined. Calcifying diploid and noncalcifying haploid cells (Roscoff culture collection 1216 and 1217) were acclimated to present-day and elevated CO2 partial pressures (PCO2; 38.5 vs. 101.3 Pa, ., 380 vs. 1000 matm) under low and high light (50 vs. 300 mmol photons m-2 s-1). Growth rates as well as quotas and production rates of C and N were measured. Sources of inorganic C for biomass buildup were using a 14C disequilibrium assay. Photosynthetic O2 evolution was measured as a function of dissolved inorganic C and light by means of membrane-inlet mass spectrometry. The diploid stage responded to elevated PCO2 by shunting resources from the production of particulate inorganic C toward organic C yet keeping the production of total particulate C constant. As the effect of ocean acidification was stronger under low light, the diploid stage might be less affected by increased acidity when energy availability is high. The haploid stage maintained elemental composition and production rates under elevated PCO2. Although both life-cycle stages involve different ways of dealing with elevated PCO2, the responses were generally modulated by energy availability, being typically most pronounced under low light. Additionally, PCO2 responses resembled those induced by high irradiances, indicating that ocean acidification affects the interplay between energy-generating processes (photosynthetic light reactions) and processes competing for energy (biomass buildup and calcification). A conceptual model is put forward explaining why the magnitude of single responses is determined by energy availability.

Egg and early larval stages of Baltic cod, Gadus morhua duirng ocean acidification experiments, 2012

The accumulation of carbon dioxide in the atmosphere will lower the pH in ocean waters, a process termed ocean acidification (OA). Despite its potentially detrimental effects on calcifying organisms, experimental studies on the possible impacts on fish remain scarce. While adults will most likely remain relatively unaffected by changes in seawater pH, early life-history stages are potentially more sensitive, due to the lack of gills with specialized ion-regulatory mechanisms. We tested the effects of OA on growth and development of embryos and larvae of eastern Baltic cod, the commercially most important fish stock in the Baltic Sea. Cod were reared from newly fertilized eggs to early non-feeding larvae in 5 different experiments looking at a range of response variables to OA, as well as the combined effect of CO2 and temperature. No effect on hatching, survival, development, and otolith size was found at any stage in the development of Baltic cod. Field data show that in the Bornholm Basin, the main spawning site of eastern Baltic cod, in situ levels of pCO2are already at levels of 1,100 µatm with a pH of 7.2, mainly due to high eutrophication supporting microbial activity and permanent stratification with little water exchange. Our data show that the eggs and early larval stages of Baltic cod seem to be robust to even high levels of OA (3,200 µatm), indicating an adaptational response to CO2.

Transplanting diglossia: attitudes towards Standard and Cypriot Greek among London’s Greek Cypriot community

The linguistic situation in Greek-speaking Cyprus has been traditionally described as a textbook case of diglossia à la Ferguson (1959) with Standard Modern Greek (SModGr) being labelled as the High variety and Cypriot Greek (CypGr), the regional ModGr variety of Cyprus, being labelled the Low variety (Arvaniti, 2011; Moschonas, 1996). More recently, however, it has been proposed that the linguistic repertoire available to speakers features an array of forms of CypGr, which is best described as a continuum ranging from basilectal to acrolectal varieties (Katsoyannou et al., 2006; Tsiplakou et al., 2006). The basilectal end encompasses low prestige varieties predominantly spoken in rural areas. The acrolectal end is occupied by the version of SModGr used in the public domain in Cyprus (Arvaniti, 2006/2010). SModGr is known to carry high prestige in Cyprus. Speakers of CypGr describe speakers of the standard as more attractive, more intelligent, more interesting and more educated than speakers of the Cypriot dialect (Papapavlou, 1998). In this paper, I explore the relation between SModGr and CypGr in a diasporic setting, namely, the Greek Cypriot community of London. The United Kingdom is home to a sizeable Greek Cypriot community, whose population is presently estimated to fall between 200,000 and 300,000 individuals (Christodoulou-Pipis, 1991; National Federation of Cypriots in the UK). Similarly to the Cyprus homeland, the members of the Greek Cypriot parikia (‘community’) share a rich linguistic repertoire, which, in addition to varieties of Greek, crucially includes English. As is often the case with diasporas, the parikia does not form a homogeneous speech community in that not all of its members have an equally good command of Greek or even English. Rather, different types of monolingual and bilingual speakers are found including a large number of heritage speakers in the sense of Benmamoun et al. (2013), Montrul (2008, 2015) and Polinsky & Kagan (2007). Twenty British-born heritage speakers of CypGr were interviewed on their attitudes towards the different varieties of Greek. Results indicate that the prestige relation between SModGr and CypGr that holds in Cyprus has been transplanted to the parikia. SModGr is widely perceived as the prestigious variety and is described in positive terms (‘correct’, ‘proper’). The use of CypGr, on the other hand, enjoys covert prestige: it is perceived as an index of solidarity and in-group membership but at the same time is also viewed by heritage speakers as reminiscent of the hardship and lack of education of the generation that brought CypGr to the UK. In certain cases, the use of CypGr by heritage speakers is actively discouraged by the first generation not only in the public domain but also in private domains such as the home. Active discouragement targets both lexical and grammatical variants that are traditionally associated with basilectal varieties of CypGr, and heritage language features, especially the adoption of morphologically adapted loanwords from English.
