Reflecting on time, timing and timeliness in public sector supply networks

Despite recent research on time (e.g. Hedaa & Törnroos, 2001), consideration of the time dimension in data collection, analysis and interpretation in research in supply networks is, to date, still limited. Drawing on a body of literature from organization studies, and empirical findings from a six-year action research programme and a related study of network learning, we reflect on time, timing and timeliness in interorganizational networks. The empirical setting is supply networks in the English health sector wherein we identify and elaborate various issues of time, within the case and in terms of research process. Our analysis is wide-ranging and multi-level, from the global (e.g. identifying the notion of life cycles) to the particular (e.g. different cycle times in supply, such as daily for deliveries and yearly for contracts). We discuss the ‘speeding up’ of inter-organizational ‘e’ time and tensions with other time demands. In closing the paper, we relate our conclusions to the future conduct of the research programme and supply research more generally, and to the practice of managing supply (in) networks.

An investigation to determine the influence of illumination sources on colour discrimination in normal subjects and smokers

Accurate colour vision testing requires using the correct illumination. With the plethora of 'daylight' lamps available, is there a cost-effective alternative to the discontinued MacBeth Easel lamp? Smoking is a known risk factor for macula degeneration. As the macula is responsible for colour discrimination, any toxin that affects it has the potential to influence colour discrimination. Aims: To find a costeffective light source for colour vision testing. To investigate the effect of smoking on colour discrimination. To explore how deuteranomalous trichromats compare with normal trichromats. Methods: Using the Ishihara colour vision test subjects were classified into the groups: 'Normal/Control', 'Smoker/Test', and 'Case Study' (subjects who failed the screening test and did not smoke). They completed the Farnsworth Munsell 100 Hue test under each of the three light sources: Phillips EcoHalo Twist (tungsten halogen - THL), Kosnic KCF07ALU/GU10-865 (compact fluorescent- CFL), and Deal Guardian Ltd. GU103X2WA4B-60 (light-emitting diode - LED) Results: 42 subjects took part in the study: 18 in the Normal/Control group, 18 in the Smoker/Test group, and 6 in the Case Study group. For the Normal/Control group the total error scores (TESs) were significantly lower with the CFL than with the THL (p = 0.017) as it was for the Case Study group (p = 0.009). No significant differences were found between the Normal/Control group and the Smoker/Test group for each light source. Decision tree analysis found pack years to be a significant variable for TES. Discussion: All three light sources were comparable with previous studies. The CFL provided better colour discrimination than the LED despite them both being 6500 K. Deuteranomalous trichromats showed a greatest deviation than normal trichromats using the LED. Conclusions: The Kosnic KCF07ALU/GU10-865 is a cost-effective alternative for colour vision testing. Smoking appears to have an effect on colour vision, but requires further investigation.

The sound of silence. Lesbian, gay, bisexual and transgender discrimination in 'inclusive organizations'

Most studies on diversity and discrimination in the workplace have focused on 'visible' minorities such as gender or race, often neglecting the experiences of invisible minorities such as lesbian, gay, bisexual and transgender (LGBT) workers. In this paper we explore the practices of inclusion/exclusion of LGBTs in the workplace in Italian social cooperatives, which are specifically founded to create employment for people who are disadvantaged in the labour market. The study examines how organizations, which have an ethos focused on inclusion and mainly employ workers from specific social minority groups, manage the inclusion of LGBT workers. We also explore the experience of LGBT workers within these organizations. The paper reports that the culture of silence existing in the five organizations studied prevents LGBT employees from constructing a work identity which encompasses their sexual identity and prevents the organizations from achieving their aim of being fully inclusive workplaces. © 2013 British Academy of Management.

A közérdek védelmének intézményei Public-Private Partnership esetében = Institutional approaches to protecting public interest in Public-Private Partnership projects

A tanulmány a Public-Private Partnership (PPP) egyik nagy kérdésének megközelítéseit vizsgálja: miként védhető a közérdek e projektekben. Piaci és nem piaci megoldásokat tesz az elemzés mérlegre, valamint kitér arra, hogy miért különleges a PPP projektek esetében a közérdek védelmének kérdése. A szabályozott verseny körülményeinek kialakítása több megközelítésben is perdöntő kérdés a PPP értéknövelésének előmozdításához, bár a létező megoldások nem mentesek anomáliáktól. A képviseleti demokrácia intézményi működésének támogatására pedig a társadalmi részvétel megoldásait javasolja az irodalom. E megközelítés is több formájában, többféle céllal és szintén kihívásokkal segítheti az értéknövelő PPP projekteket. A tanulmány az elvi lehetőségek értékelő elemzését követően a megvalósítás realitásait is mérlegre teszi. = This study focuses on a key issue in Public-Private Partnership (PPP) projects: how may public interest be protected. It assesses market based and non market based approaches, and also explains why PPP projects are peculiar when addressing the protection of public interest. Setting up the conditions for simulated competition is of paramount importance for different reasons in order to enable value creating PPP projects. Existing solutions however are not without anomalies. To promote the institutions of democracy, participatory solutions are recommended in the literature. That approach may help value creating PPP projects in various forms, with a range of objectives and challenges. The study concludes the analytical assessment of options by highlighting the realistic conditions of implementation.

Szemléletbeli dilemmák a Public-Private Partnership menedzsmentjében = Management dilemmas in Public-Private Partnership projects

A tanulmány a Public-Private Partnership (PPP) immanens logikai kihívásai közül két kiemelt kérdést elemez: az állami fél közszolgálati-közigazgatási beágyazottságából eredő dilemmákat, valamint az állami és a magánfél eltérő kulturális hátteréből eredő feszültségek jellemzőit. A PPP projektek gyakorlati megvalósítása szempontjából e két kardinális kérdés kifinomult elméleti hátterébe nyújt bepillantást. A közszolgáltatási dilemmák közül azonosítja és tárgyalja a jogszerűség vs. eredményesség, a hatékonyság vs. eredményesség, a centralizáció vs. decentralizáció, a közérdek vs. egyéni szabadságjogok védelme, valamint a kormányzat kicsinyítése vs. jogbiztonság védelme, és a vállalkozói szemlélet vs. közszolgálatiság közti egyensúlyozás kihívásait. Az állami és az üzleti fél kulturális különbözőségének központi motívumaként a döntéshozatalbeli különbséget ragadja meg, és a bizalom szerepét hangsúlyozza a működőképes modell megtalálásának lehetőségeként. = This study analyses two cardinal issues of Public-Private Partnership (PPP) projects’ immanent challenges: the management dilemmas of public services/governance, and the tensions between the private and public parties due to their different cultural imbeddedness. It provides theoretical insights into these two issues of practical relevance. As public service management dilemmas, it identifies the trade-offs between rights vs. effectiveness, efficiency vs. effectiveness, centralization vs. decentralization, protecting the public interest vs. individual freedom, minimizing government vs. protecting human rights, the entrepreneurial approach vs. public service ethos. The study captures the cultural difference between the public and the private parties in their different approaches to decision making, while it concludes that the role of trust is key in finding feasible solutions for PPP models.

Price discrimination in asymmetric Cournot oligopoly

In this article we examine the eects of third degree price discrimination in asymmetric Cournot oligopolies. We show that the average price is not affected by the extent of price discrimination. We nd that the asymmetry between firms is reflected only by the output produced for the lowest-valuation consumers and firms produce equal quantities to the other consumer groups.

Civil service reform trends in public personnel management: Experiences from the Commonwealth of the Bahamas

This study has explored the potential for implementing a merit-based public personnel system in The Bahamas, a former British colony in The Commonwealth Caribbean. Specifically, the study evaluated the use of merit-based public personnel management practices in areas of recruitment, selection, promotion, training and employee development and performance evaluation. Driving forces and barriers which impact merit system successes and failures as well as strategies for institutionalizing merit system practices are identified. Finally the study attempted to apply the developmental model created by Klingner (1996) to describe the stage of public personnel management in The Bahamas. The data for the study was collected through in-depth interviews with expert observers. ^

A study of leadership behaviors for Breaking Ranks leaders in public secondary schools

This research will investigate what it will take to develop principals who will embrace the recommendations of reform as proposed by National Association of Secondary School Principals (NASSP, 1996) in the Breaking Ranks document. Breaking Ranks is based on the belief that it is within the dynamics of the school culture that principals must gain insight into strategies for improving the schools for which they are held responsible. Given this context, it is important to examine perspectives that are held by principals who lead schools that embrace the concepts of reform as proposed by NASSP, thereby, could be deemed “Breaking Ranks” schools. It is within these schools that the new role of the principal develops. NASSP has identified seven key recommendations for leadership development; “attributes that need nourishing” (p. 12) for the success of school reform. The seven recommendations are included in Breaking Ranks. ^ The purpose of this study is to identify and describe how principals put the seven recommendations into practice as they function in their schools. In addition, this study will gather information on the characteristics, support, skills, and training these principals identify as critical aspects and components of their success. This is a study of principal leadership at four high school sites where “Breaking Ranks” principals have been identified. ^ This research plan will be designed to utilize an inquiry-based process with a panel of experts and four “Breaking Ranks” principals. This study will describe: (1) how a panel of experts identify what they believe needs to be done in order to put the recommendations of the Breaking Ranks document into practice and their identification of principals who are breaking ranks; (2) how identified principals say they have been able to put the recommendations of the Breaking Ranks document into practice; (3) How both groups identify and describe: (a) the characteristics and behaviors of a “Breaking Ranks” principal; (b) the new leadership skills as described by the seven recommendations identified in the Breaking Ranks document; (c) the support necessary in order to meet the recommendations in the Breaking Ranks document; and (d) The training needed in order to become “Breaking Ranks” principals; and (4) how the process of creating “Breaking Ranks” principals can be described by experts who have studied it theoretically and principals who have demonstrated it in their schools. ^

Carbon (d13c) and Nitrogen (d15n) Isotopic Discrimination in Mangroves in Florida Coastal Everglades as a Function of Environmental Stress

Isotope signatures of mangrove leaves can vary depending on discrimination associated with plant response to environmental stressors defined by gra­dients of resources (such as water and nutrient limitation) and regulators (such as salinity and sul­fide toxicity). We tested the variability of man­grove isotopic signatures (d13C and d15N) across a stress gradient in south Florida, using green leaves from four mangrove species collected at six sites. Mangroves across the landscape studied are stressed by resource and regulator gradients repre­sented by limited phosphorus concentrations com­bined with high sulfide concentrations, respec­tively. Foliar d13C ratios exhibited a range from ­ 24.6 to –32.7‰, and multiple regression analysis showed that 46% of the variability in mangrove d13C composition could be explained by the differ­ences in dissolved inorganic nitrogen, soluble reac­tive phosphorus, and sulfide porewater concentra­tions. 15N discrimination in mangrove species ranged from –0.1 to 7.7‰, and porewater N, salin­ity, and leaf N:Pa ratios accounted for 41% of this variability in mangrove leaves. The increase in soil P availability reduced 15N discrimination due to higher N demand. Scrub mangroves (<1.5 m tall) are more water-use efficient, as indicated by higher d13C; and have greater nutrient use efficiency ratios of P than do tall mangroves (5 to 10 m tall) existing in sites with greater soil P concentrations. The high variability of mangrove d13C and d15N across these resource and regulator gradients could be a con­founding factor obscuring the linkages between mangrove wetlands and estuarine food webs. These results support the hypothesis that landscape fac­tors may control mangrove structure and function, so that nutrient biogeochemistry and mangrove-based food webs in adjacent estuaries should ac­count for watershed-specific organic inputs.

A study of the differences among African -American, Hispanic, and Anglo women on the perceived barriers and strategies to career advancement in public school administration

Women have been traditionally excluded from the ranks of principals and district administrators in public school systems throughout the country. Traditionally, Anglo women have been more successful than African American and Hispanic women in breaking down the barriers that impede their ascension to the top. The purpose of this study was to ascertain how African American, Hispanic, and Anglo higher-level female administrators perceive the barriers that hinder their progress, the effects of the barriers, and the strategies to overcome the barriers. ^ Two hundred, sixty female administrators employed with Miami-Dade County Public Schools and serving in the role of principal or higher were mailed a questionnaire consisting of 49 questions centering on personal and professional characteristics, perceptions of barriers, perceived effects of barriers, and strategies to overcome the barriers. One hundred, seventy-five questionnaires were returned. To analyze the respondents' personal and professional characteristics, cross tabulations were conducted on the demographic information and on the strategies. ANOVA was conducted on the barriers and the effects of the barriers by ethnic groups. Tukey's test for post-hoc comparisons was utilized to identify groups with means significantly divergent from those of other ethnicities. ^ The data revealed that Hispanic female higher-level administrators who returned the questionnaire were more likely to be married and have children as compared to Anglo and African American female administrators. When addressing the barriers to career success, African American females had a higher mean score on 14 of the 17 barriers to career success as compared to the other ethnic groups. Hispanic female administrators proved to be more successful in utilizing the strategies to overcome career barriers. The strategy, forming a “New Girl Network,” was the least utilized with 79 of the respondents reporting that they had never used it. ^ It is concluded that there is strong need for female administrators to network, mentor, and support one another. Also, it is imperative that the success of particular groups in certain areas is shared with others. ^

Public Service Motivation in Public and Nonprofit Service Providers: The Cases of Belarus and Poland

The work motivation construct is central to the theory and practice of many social science disciplines. Yet, due to the novelty of validated measures appropriate for a deep cross-national comparison, studies that contrast different administrative regimes remain scarce. This study represents an initial empirical effort to validate the Public Service Motivation (PSM) instrument proposed by Kim and colleagues (2013) in a previously unstudied context. The two former communist countries analyzed in this dissertation—Belarus and Poland— followed diametrically opposite development strategies: a fully decentralized administrative regime in Poland and a highly centralized regime in Belarus. The employees (n = 677) of public and nonprofit organizations in the border regions of Podlaskie Wojewodstwo (Poland) and Hrodna Voblasc (Belarus) are the subjects of study. Confirmatory factor analysis revealed three dimensions of public service motivation in the two regions: compassion, self-sacrifice, and attraction to public service. The statistical models tested in this dissertation suggest that nonprofit sector employees exhibit higher levels of PSM than their public sector counterparts. Nonprofit sector employees also reveal a similar set of values and work attitudes across the countries. Thus, the study concludes that in terms of PSM, employees of nonprofit organizations constitute a homogenous group that exists atop the administrative regimes. However, the findings propose significant differences between public sector agencies across the two countries. Contrary to expectations, data suggest that organization centralization in Poland is equal to—or for some items even higher than—that of Belarus. We can conclude that the absence of administrative decentralization of service provision in a country does not necessarily undermine decentralized practices within organizations. Further analysis reveals strong correlations between organization centralization and PSM for the Polish sample. Meanwhile, in Belarus, correlations between organization centralization items and PSM are weak and mostly insignificant. The analysis indicates other factors beyond organization centralization that significantly impact PSM in both sectors. PSM of the employees in the studied region is highly correlated with their participation in religious practices, political parties, or labor unions as well as location of their organization in a capital and type of social service provided.

A critical discourse analysis on the (self) representation of Hillary R. Clinton in public discourse

El rol de la mujer dentro de la sociedad ha sido y aún es un tema de mucha controversia. Incluso en nuestra sociedad, se suscitan debates sobre si les está permitido a las mujeres ocupar ciertos ámbitos laborales que han estado siempre dominados por una fuerte presencia masculina, como es el caso del ámbito político. Además, en muchos países aún ni siquiera están reconocidos los derechos de las mujeres, y mientras que, en otras culturas, a pesar de que la ley vela por los derechos humanos sin importar la raza, la religión o el género, la realidad es que incluso en las culturas más desarrolladas existe desigualdad de género y estereotipos que afectan el desenvolvimiento de la mujer. Sin embargo, a pesar de que aun la desigualdad de género está presente en la sociedad, es innegable que la situación actual es mucho más positiva para la implicación de las mujeres incluso dentro de ámbitos de la sociedad, que décadas atrás sería impensable, como la política. En esta línea, toda esta situación ha suscitado el interés de muchos investigadores y lingüistas, que han dedicado tiempo a investigaciones sobre las relaciones entre discurso y género, y sobre la representación mediática de mujeres que tienen cierta influencia en el ámbito público, y cómo la desigualdad de género afecta su imagen pública. Si bien es cierto, durante mucho tiempo el ámbito de la política ha estado dominado por presencia masculina, ahora la situación ha cambiado. En las últimas décadas, se ha hecho evidente una gran presencia de mujeres dentro de la política, mujeres que a comparación de la situación vivida décadas atrás, ahora tienen la posibilidad de presentarse incluso como candidatas a la presidencia, como es el caso de Hillary Clinton. En este sentido muchas corrientes feministas han contribuido en gran medida a esta nueva situación. Ahora bien, en vista de toda esta situación, el presente estudio de investigación intentará dar respuesta a las siguientes preguntas. ¿Hasta qué punto los estereotipos de género están aún presentes en la sociedad? ¿La representación mediática de una figura política está realmente basada en su conducta y en su actividad discursiva, o está influida por esquemas e ideas preconcebidas de género? Teniendo en cuenta que hoy en día hay una mayor presencia femenina dentro del ámbito político, una de mis hipótesis iniciales es que la situación de los estereotipos de género ha disminuido. Además, se espera que la forma en la que Hillary Clinton se representa a sí misma como una mujer y como una política esté menos perjudicada por estos esquemas. El objetivo de este estudio es, primeramente, llevar a cabo un análisis sobre diez discursos de Hillary Clinton, desde el 15 de junio de 2015, fecha en la que Hillary Clinton lanzo su candidatura a la presidencia, hasta el 26 de abril de 2016, para a través de este análisis poder identificar como Hillary Clinton se caracteriza a sí misma en sus discursos políticos, y asimismo identificar si los esquemas convencionales sobre género afectan su auto representación. Con este objetivo, el enfoque de este estudio se va a centrar en análisis cuantitativos y cualitativos sobre la frecuencia de palabras, seguido de un análisis crítico del discurso sobre la auto representación de Hillary en sus discursos. Además, siguiendo la línea de investigación de Tannen (1996), se realizará un análisis sobre los usos de los pronombres “nosotros” y “yo”, para adquirir una mayor perspectiva sobre esta situación. Seguidamente, teniendo en cuenta que los medios de comunicación reflejan ideologías sociales, este estudio ha sido también diseñado para analizar diez artículos de noticias sobre los discursos previamente analizados de Hillary Clinton. De esta manera, se examinará si los estereotipos de género están presentes en la representación mediática de Hillary Clinton, para seguidamente analizar si la interpretación mediática de la candidata a la presidencia está realmente relacionada con los discursos analizados o, si por lo contrario están influidos por estereotipos y esquemas de género. Para cumplir con este objetivo, los datos recopilados para este corpus consisten en exactamente diez artículos que reporten sobre los discursos estudiados en el primer análisis, y la actuación de Hillary Clinton. Estos artículos fueron recogidos de cuatro de los periódicos más importantes de los Estados Unidos, que son New York Times, Wall Street Journal, Los Angeles times y The Washington Post. En este caso el análisis estará centrado en la frecuencia de palabras y en el uso de reporting verbs, siguiendo la línea de investigación de Caldas – Coulthard (1995). Se espera que el presente estudio pueda servir para mayores investigaciones sobre cuestiones de género, y de esta manera contribuir a la creación de teorías que puedan explicar mejor la situación de las mujeres dentro de la política. Para finalizar, aún queda mucho que investigar en esta disciplina, e incluso más por descubrir
