Partner selection for reverse logistics centres in green supply chains: a fuzzy artificial immune optimization approach

The design of reverse logistics networks has now emerged as a major issue for manufacturers, not only in developed countries where legislation and societal pressures are strong, but also in developing countries where the adoption of reverse logistics practices may offer a competitive advantage. This paper presents a new model for partner selection for reverse logistic centres in green supply chains. The model offers three advantages. Firstly, it enables economic, environment, and social factors to be considered simultaneously. Secondly, by integrating fuzzy set theory and artificial immune optimization technology, it enables both quantitative and qualitative criteria to be considered simultaneously throughout the whole decision-making process. Thirdly, it extends the flat criteria structure for partner selection evaluation for reverse logistics centres to the more suitable hierarchy structure. The applicability of the model is demonstrated by means of an empirical application based on data from a Chinese electronic equipment and instruments manufacturing company.

Supply Chain Resilience? Definition of concept and its formative elements.

The objective of this paper is to conceptualize Supply Chain Resilience (SCRes) and identify which supply chain capabilities can support the containment of disruptions and how these capabilities affect SCRes. Through a systematic and structured review of literature, this paper provides insights into the conceptualization and research methodological background of the SCM field. A total of one hundred and thirty four carefully selected refereed journal articles were systematically analyzed leading to the introduction of a novel definition for SCRes, which the authors view as the as “the ability to proactively plan and design the Supply Chain network for anticipating unexpected disruptive (negative) events, respond adaptively to disruptions while maintaining control over structure and function and transcending to a post-event robust state of operations, if possible, more favorable than the one prior to the event, thus gaining competitive advantage”. Finally, a critical examination of existing conceptual frameworks for understanding the relationships between the SCRes concept and its identified formative elements, is taking place.

Hoe beïnvloeden de marktkenmerken de belemmeringen voor innovatie in de utiliteitsbouw in Nederland?

How do the market characteristics influence the obstacles to innovation in the non-residential building industry in the Netherlands? Innovation can make an important contribution to the firm’s competitive advantage. Within the nonresidential building industry in the Netherlands the competition is very high. Therefore there should be enough motivation to innovate. The building industry has been severely hit by the economic crisis in the past years in the Netherlands, which made the competition even harder. Nevertheless the industry has a poor reputation on innovation and is known as a conservative industry. In the past decade the industry and government have put a lot of effort into making the sector more innovative. Sadly the innovation level has hardly improved. Why does the building industry fail to make itself more innovative? To make a contribution to this issue a research can be conducted to investigate the causes of this low innovation level. Research This thesis tends to make more clear about the causes of the low innovation level. Based on an extensive field research as well as a literature research the main question of this thesis is: How do the market characteristics influence the obstacles to innovation in the non-residential building industry in the Netherlands? The structure is based on qualitative research through case study research. Therefore a conceptual model is structured which is used as a fundamental base. Within the first case 21 interviews were held with the prime actors which played a direct role in the innovation level of non-residential projects. These prime actors are clients, consultancy agencies and building contractors. Also two panel discussions were organized to discuss the outcomes of the interviews. In the second and third case a part of certain market characteristics of the conceptual model were changed. The main reason to investigate these cases is to substantiate the results of the first case.

Role of NleH, a type III secreted effector from attaching and effacing pathogens, in colonization of the bovine, ovine, and murine gut

The human pathogen enterohemorrhagic Escherichia coli (EHEC) O157:H7 colonizes human and animal gut via formation of attaching and effacing lesions. EHEC strains use a type III secretion system to translocate a battery of effector proteins into the mammalian host cell, which subvert diverse signal transduction pathways implicated in actin dynamics, phagocytosis, and innate immunity. The genomes of sequenced EHEC O157:H7 strains contain two copies of the effector protein gene nleH, which share 49% sequence similarity with the gene for the Shigella effector OspG, recently implicated in inhibition of migration of the transcriptional regulator NF-kappaB to the nucleus. In this study we investigated the role of NleH during EHEC O157:H7 infection of calves and lambs. We found that while EHEC DeltanleH colonized the bovine gut more efficiently than the wild-type strain, in lambs the wild-type strain exhibited a competitive advantage over the mutant during mixed infection. Using the mouse pathogen Citrobacter rodentium, which shares many virulence factors with EHEC O157:H7, including NleH, we observed that the wild-type strain exhibited a competitive advantage over the mutant during mixed infection. We found no measurable differences in T-cell infiltration or hyperplasia in colons of mice inoculated with the wild-type or the nleH mutant strain. Using NF-kappaB reporter mice carrying a transgene containing a luciferase reporter driven by three NF-kappaB response elements, we found that NleH causes an increase in NF-kappaB activity in the colonic mucosa. Consistent with this, we found that the nleH mutant triggered a significantly lower tumor necrosis factor alpha response than the wild-type strain.

Varumärkesstärkande samhällsansvar : En studie om hur CSR påverkar konsumenters attityder

Företags samhällsansvar (CSR) har utvecklats från ett fokus på etik till prestation och att således kunna fungera som ett strategiskt verktyg för differentiering och det är idag allmänt vedertaget för företag att använda sig av CSR med antagandet att detta genererar konkurrensfördelar. Samtidigt som CSR påvisats kunna skapa mervärde till ett företags varumärke ställs numera också krav från konsumenter att företag tar ett samhällsansvar. Det har däremot uppmärksammats att konsumenters medvetenhet om företags CSR-initiativ är låg, vilket kan anses problematiskt i och med de investeringar företag lägger på CSR och om detta således tas i beaktande vid konsumenters utvärdering av företag. Uppsatsens syfte är därmed att förklara om och hur CSR påverkar konsumenters attityd till ett företags varumärke samt ifall detta innebär ett mervärde och därmed varumärkesstärkande. För att uppnå syftet genomfördes en kvantitativ undersökning och enkäter skickades ut till studenter vid Högskolan Dalarna där totalt 682 respondenter slutförde enkäten. Resultaten visar en låg grad av medvetenhet, men att konsumenter med en högre grad av medvetenhet uppvisar mer fördelaktiga attityder till företag som tar ett samhällsansvar. Det framkommer också att dessa attityder genererar företag immateriella värden vilket senare teoretiskt förklaras innebära ett mervärde och därmed varumärkesstärkande. Studien landar i att CSR kan användas av företag för att stärka sitt varumärke, men finner dock en begränsning gällande konsumenters låga medvetenhet om företags CSR-initiativ.

Utveckling av lojalitetsprogram - individanpassade erbjudanden : Marknadsföring genom CRM-strategier

Den ökade konkurrenssituationen mellan företag är ett resultat på att handeln har globaliserats. Konsumenter är idag mer medvetna om vad företag har att erbjuda, och det är lätt att välja alternativa företag om ett specifikt företag inte lever upp till konsumentens förväntningar. Detta ställer krav på att företag ständigt måste arbeta med och utveckla sina strategier för att skapa konkurrensfördelar. Idag arbetar många företag med lojalitetsprogram som är ett typexempel på en CRM-strategi. CRM-strategier och lojalitetsprogram syftar till att göra konsumenten mer lojal, för att möjliggöra att konsumenten skall välja att göra återupprepande och mer frekventa köp. Lojalitetsprogrammen måste dock uppdateras och förändras, för att ständigt kunna vara konkurrenskraftiga. Företag arbetar därmed för att skapa ett mervärde, det vill säga erbjuda en servicelösning som är utöver vad konsumenten förväntar sig att få från företag. Kundlojalitet kan utvecklas genom att företag skapar långsiktiga relationer med konsumenterna, och en relation mellan parterna kan utvecklas genom att företag lyssnar på konsumenterna, för att få reda på dess behov och önskemål. Forskning indikerar att individanpassade erbjudanden kan bidra till att konsumenterna än mer tenderar att bli lojala, detta eftersom individanpassade erbjudanden är erbjudanden som baseras på konsumentens unika köpbeteende, vilket möjliggör för träffsäkerhet och relevans. Syftet med denna studie är att mäta konsumenters efterfrågan på individanpassade erbjudanden, för att undersöka om konsumenterna faktiskt efterfrågar och kommer ta till sig dessa erbjudanden. Frågeställningarna är; på vilket sätt kan efterfrågan på individanpassade erbjudanden bidra till ett företags konkurrensfördelar samt på vilket sätt skiljer sig efterfrågan på individanpassade erbjudanden beroende på butikernas geografiska placering. Studien är baserad på en kvantitativ surveyundersökning riktad till konsumenter, med en kvalitativ semi-strukturerad intervju för att erhålla viktig information vid utformandet av frågeformuläret. Resultatet för studien visade att konsumenter värdesätter att få individanpassade erbjudanden, och att dessa erbjudanden kan bidra till ett företags konkurrensfördelar eftersom erbjudandena möjliggör att servicekvaliteten kan öka vilket innebär att dessa erbjudanden kan upplevas ha ett mervärde. I denna studie återfanns dock inte några skillnader på efterfrågan av individanpassade erbjudanden beroende på butikernas geografiska placering.

Innovations in Hospitality Human Resources: Cases from the U.S. Lodging Industry

[Excerpt] Today’s hospitality and tourism companies face complex, dramatically shifting challenges, most notably the need to compete for increasingly sophisticated customers in a global, fluid marketplace. To attract and retain the loyal cadre of customers that will ensure the organization’s success, service companies such as hospitality organizations must employ technologically advanced, yet margin sensitive, product and pricing strategies and practices that will differentiate themselves to their intended market. Even more importantly, these service organizations need to devise strategies that will capture and retain the most important yet, from a financial perspective, unrecognized asset on the balance sheet: the employees that design and deliver the service to the customer base. Human resource strategists (i.e. Becker & Gerhart, 1996; Cappelli & Crocker-Hefter, 1996; O’Reilly & Pfeffer, 2000; Pfeffer, 1998; Ulrich, 1997), including those who take a hospitality perspective (i.e. Baumann, 2000; Hume, 2000; Worcester, 1999) advocate a renewed attention to the investment in employees or “human capital” as a source of strategic competitive advantage.

Gestão da cadeia de suprimento e vantagem competitiva: uma análise em setores industriais a partir da visão relacional

This work has as its main purpose to investigate the contribution of supply chain management in order to obtain competitive advantage by companies from the textile industry and from Ceará footwear industry, focusing its analysis mainly in the interorganizational relations (dyadic). For this, the theoretical referential contemplates different explanatory streams of the competitive advantage, detaching the relational perception of the resources theory, as well as, the main presuppositions of the supply chain management which culminates with the development of an analysis sample that runs the empirical study; the one which considers an expanded purpose of the supply chain which includes the government and the abetment institutions as institutional environment representatives. Besides supply chain management consideration as a competitive advantage source, the work also tried to identify other possible competitive advantage sources for the companies of the investigated sectors. It represents a study of multiple interpretive cases, having four cases as a total; meaning two cases in each one of the sectors, which used as a primary data collecting instrument a semi-structured interview schedule. Different methods were used for the data analysis, the content analysis and the constant comparison methods, the analytical procedure originated from the grounded theory research strategy, which were applied the Atlas/ti software recourse. Considering the theoretical referential and the used analysis sample, four basic categories of the work were defined, including its respective proprieties and dimensions: (1) characteristics concerning to the relationship with the supplier; (2) the company relations with the government; (3) the company relations with the abetment institutions and; (4) obtaining sources of competitive advantage. In general, the applied research in the footwear sector revealed that in the relationships of the researched companies related to its suppliers, there is a predominance of the partnership system and the main presuppositions of the supply chain management are applied which contributes for the acquisition of the relational competitive advantage; while in the textile sector, only some of these presuppositions are applied, with little contribution for the relational competitive advantage. The main resource which was accessed by the companies in both sectors through its relationships with the government and the abetment institutions are the tax incentives which, for the footwear companies, contribute for the acquisition of the temporary competitive advantage in relation to the contestants who do not own productive installations in the Northeast region, it also conducts to a competitive parity situation in relation to the contestants who own productive installations in the Northeast region and to the external market contestants; while for the companies of the textile sector, the tax incentives run the companies to a competitive parity situation in relation to its contestants. Furthermore, the investigated companies from the two sectors possess acquisition sources of the competitive advantage which collimate with different explanatory streams (industrial analysis, resources theory, Austrian school and the dynamic capabilities theory), although there is a predominance of the product innovation as a competitive advantage source in both sectors, due to the bond of these with the fashion tendencies

Relações interorganizacionais e eficiência coletiva: um estudo de caso no arranjo produtivo local de confecções do Agreste de Pernambuco

This work is a study in the Local Productive Arrangement of confections from Agreste of Pernambuco, as a relevant sector in economic and social aspect. This research has as central aim to understand how the inter-organizational relations influence the collective efficiency of arrangement. The theoretical framework employed highlights the approaches that deal with the benefits of business agglomeration for the develop­ment of firms and regions. It has discussed the approach of small and medium enter­ prises and industrial districts (SCHMITZ, 1997), which introduce the concept of col­ lective efficiency, explaining that only those externalities explained by Marshall (1996) are not sufficient to explain the competitive advantage of enterprises, expand­ing the idea that organizations achieve competitive advantage not acting alone. To examine the influences of relations in the collective efficiency, it has been taken as analytical perspective theory of social networks (GRANOVETTER, 1973, 1985; BURT, 1992; UZZI, 1997) because it has believe that this approach provides subsi­ dies for a structural analysis of social relationships in face the behavior of human ac­tion. By examining the organizations in a social network, you should understand the reason of this establishment of the relationship, their benefits, and as the information flow takes place and density of links between the actors (Powell; SMITH-DOERR, 1994). As for the methods, this study is characterized as a case study, in according to the purposed objectives, in addition to qualitative method. Also, due to recovering of the historical milestones of the arrangement, it is used a sectional approach with longitudinal perspective (VIEIRA, 2004). The primary and secondary data were used in order to understand the evolutionary process of the sector and their inter-actors re­ lationships in the arrangement for the promotion of development, for both, was used the contend and documentary analysis technique, respectively (DELLAGNELO ; SIL­VA, 2005). The approach of social networks has permitted understand that social re­lationships may extend the collective efficiency of the arrangement, and therefore need to develop policies that encourage the legalization of informal companies in ar­rangement, by showing up themselves representative. Thus, the relations estab­ lished in LPA of confections from Agreste of Pernambuco need for more effective mechanisms to broaden the collective efficiency. Therefore, this way as take place has directly benefited only a group of companies that are linked in some way the sup­portive institutions. So we can conclude that the inter-actor relations have limited the collective efficiency of LPA, being stimulated by the institutions in support only to groups of entrepreneurs, even those that produce external relations for all clustered companies

Financialisation, Capital Accumulation and Economic Development : A Theoretical and Empirical Investigation of the Nigerian Economy

The primary focus of this study is to highlight those unobtrusive, yet fundamental, factors undermining economic development in Nigeria. To begin with, it posits that the decelerating pace of capital accumulation in Nigeria, which naturally occasions rising unemployment and poverty levels, and widening inequality gap, is the result of the ‘low possibility’ of capitalist enterprises in the country of earning an adequate rate of profit from their productive processes. In turn, the ‘low possibility’ is argued to be the result of the uneven development inherent in the modern capitalist structure, the high cost of capital and of production peculiar to Nigeria, and the ineffective demand for goods made in Nigeria: these elements are viewed as been precipitated by the contradictions of the contemporary political-economic arrangement that organises the Social Structures of Accumulation. For Nigeria to ‘develop’, it is contended that the unobtrusive elements inherent in the contradiction of the political-economic economic that undermine the capitalists’ ability to earn a commensurate rate of profit in the country needs to be fully addressed first. Furthermore, this study suggests that it is crucial the country embraces knowledge-based industrialisation if it is to achieve some form of ‘competitive advantage’ in the global market, which could enable its productive processes extract a commensurate level of profit from the market. To facilitate the knowledge-based industrialisation, the state should, not only create a conducive environment for industrial development but also play the lead role in transforming the peripheral and oil dependent economy to a knowledge-based economy by coordinating business organisations and investing in high-risk innovations.

Kompetensutveckling som konkurrensmedel : En kvalitativ intervjustudie med fokus på förskollärarstudenters och förskollärares uppfattning av kompetensutveckling som konkurrensmedel

Studiens syfte handlar om huruvida kompetensutveckling kan fungera som konkurrensmedel när en kommun har för avsikt att attrahera och behålla förskollärare. Bakgrunden inleds med vilka kompetenshöjande insatser kommunen arbetat med för att bli en attraktiv arbetsgivare. Det efterföljs av en teoretisk beskrivning om hur kompetensutveckling kan fungera som konkurrensmedel samt skolan som attraktiv arbetsgivare. Metoden som användes vid insamlandet av data var semistrukturerade intervjuer. Forskningsansatsen inspirerades av fenomenologin och styrde sedan arbetet med insamlandet av data samt val av analysmetod. Då urvalet innefattade två grupper; förskollärare och förskollärarstudenter skapades en intervjuguide för respektive grupp som utformades efter studiens syfte och frågeställningar. I studiens resultat framkommer samtliga intervjupersoners upplevelse av att kompetensutveckling är något positivt. Förskollärarna såg det som en avgörande faktor vid val av arbetsgivare medan förskollärarstudenterna värderade exempelvis lön som en faktor av större betydelse. I resultatet lyfts andra övergripande faktorer som exempelvis arbetsklimat, stöd från chef och storlek på barngrupper vilka även styr intervjupersonernas val av arbetsgivare. Det lyfts också möjliga kommunspecifika utvecklingsområden samt generellt för förskolor.
