Traditional part-time grazing: a more sustainable sheep milk and cheese production in the Basque Country

[EN] The concept of sustainability when referring to food production rests, in general, on 3 main aspects: 1) respect for the environment; 2) economic and social benefits for all involved in production; and 3) production of sufficient quantity of quality food at an accessible price. In this contribution we focus on the main aspects of the traditional sheep's milk and cheese production (under the Denomination of Origin Idiazabal Cheese) in the Basque Country that contribute primarily to its sustainability. It is based on the local latxa or carranzana breeds of sheep, adapted to the mountainous terrain. The sheepherder takes advantage of local resources to reduce management costs by combining indoor dry forage and concentrates with outdoor grazing throughout lactation, according to local pasture availability, and thus avoiding having to buy large amounts of feed. This system facilitates recycling of manure, fertilising pastures and forest at the same time. Use of local breeds helps maintain biodiversity of sheep breeds. Cheese is produced industrially (44.5% of the total cheese produced in 2008) from milk of many flocks, or artisanally (38.3%) by the sheepherders with the milk from their own flocks. Transforming their own milk into cheese is advantageous for the following reasons: 1) higher economic returns as compared to selling the milk to cheese factories because cheese price directly sold to consumers is more competitive than industrial cheese sold in supermarkets; 2) increases the value of women's work (over 80% of the cheese makers are women) in the community and their self-esteem; 3) it creates rural jobs and contributes to rural development; 4) we have demonstrated both with experimental and commercial flocks that part-time grazing allows the sheepherder to obtain high yields of milk, and cheese, of high nutritional and functional quality. Currently a less sustainable, intensive sheep's milk production with foreign, imported breeds kept indoors constantly is gaining favour among milk producers because of its perceived higher economic profitability.

Family Business Succession in Austria – Satisfaction and the Incumbent-successor Relationship

The transfer of businesses contributes to the dynamics and the development of the economy in Austria. Successful transfers generate numerous positive impacts. Securing both employment and investment, creating new jobs and stimulating growth are some of these effects. Failed transfers can contribute to negative effects, including the loss of jobs and an economic slowdown. Over recent years the number of business handovers in Austria has been rising. The forecasts show that this number will remain high over the next few years. Between 2015 and 2024 more than 42,000 economically sound SMEs will face the challenge of finding an appropriate successor. This means that 26 % of all Austrian SMEs (excluding one-person businesses) and 29 % of all employees in these companies will be affected. The aim of this paper is to provide a multi-faceted discussion of the relevance of affective components in family business transfers. A “good” relationship between the successor and the departing owner fosters the success of a transfer. This relationship involves, among others, the willingness to share relevant information, openness and respect. The satisfaction (with the completed business transfer) is closely interrelated with the relationship between the successor and the departing owner. Consequently, we can assume that affective and emotional components can indeed shape the success of business transfers. Based on that, new future research opportunities are outlined.

Local Use and Management of Tasba (Senna obtusifolia) in the Traditional Food System of Sanguere Paul, North Cameroon

The purpose of this study is to examine the importance of the wild edible weed tasba (Senna obtusifolia) in Sanguéré Paul, Cameroon by examining how households use and manage the plant. This study found that local management of tasba is minimal compared to other traditional vegetables. Tasba was collected most frequently from en brousse or the communal, fallowed land which is often too degraded for traditional field crops to grow. Women subsistence farmers were closely involved with tasba as they are the ones responsible for food production within the family. Socioeconomic differences between women affects how they manage tasba and other vegetables to form a livelihood strategy to achieve food security within the family. Modifications and changes in management and use of tasba are influenced by time, proximity and income based on her perspective, preferences and resources available. Overall, tasba is an integral part of the traditional food system in Sanguéré Paul, and can play a role in the uncertain ecological and social setting of northern Cameroon.

The Relationship between Job Structure, Burnout, and Coping Methods among Public School county Bus Drivers, Bus Aides, Mechanics, and Clerical Workers

The purpose of this study was to examine the relationship between the structure of jobs and burnout, and to assess to what extent, if any this relationship was moderated by individual coping methods. This study was supported by the Karasek's (1998) Job Demand-Control-Support theory of work stress as well as Maslach and Leiter's (1993) theory of burnout. Coping was examined as a moderator based on the conceptualization of Lazarus and Folkman (1984). Two overall overarching questions framed this study: (a) what is the relationship between job structure, as operationalized by job title, and burnout across different occupations in support services in a large municipal school district? and (b) To what extent do individual differences in coping methods moderate this relationship? This study was a cross-sectional study of county public school bus drivers, bus aides, mechanics, and clerical workers (N = 253) at three bus depot locations within the same district using validated survey instruments for data collection. Hypotheses were tested using simultaneous regression analyses. Findings indicated that there were statistically significant and relevant relationships among the variables of interest; job demands, job control, burnout, and ways of coping. There was a relationship between job title and physical job demands. There was no evidence to support a relationship between job title and psychological demands. Furthermore, there was a relationship between physical demands, emotional exhaustion and personal accomplishment; key indicators of burnout. Results showed significant correlations between individual ways of coping as a moderator between job structure, operationalized by job title, and individual employee burnout adding empirical evidence to the occupational stress literature. Based on the findings, there are implications for theory, research, and practice. For theory and research, the findings suggest the importance of incorporating transactional models in the study of occupational stress. In the area of practice, the findings highlight the importance of enriching jobs, increasing job control, and providing individual-level training related to stress reduction.

Percurso profissional. Destaque para a análise da produção de resíduos urbanos no Alentejo Central - portugal e utilização do modelo DEA na definição da meta da recolha seletiva

Neste trabalho de Projeto efetua-se o desenvolvimento do tema da produção de Resíduos Urbanos (RU) no Alentejo Central, utilizando-se o modelo DEA (Data Envelopment Analysis) para a análise das metas da recolha seletiva estabelecidas para 2020. Genericamente, quanto maior é o grau de desenvolvimento económico de um território, maior é a taxa de urbanização e maior é também a quantidade de resíduos urbanos produzidos por habitante. O rendimento e a urbanização são variáveis altamente correlacionadas, quando aumenta o rendimento disponível e os padrões de vida, aumenta também o consumo de bens e serviços de modo correspondente, o que leva ao aumento da quantidade de resíduos gerados. Assim, tendo em conta os impactos locais que os RU abandonados trazem, e com o objetivo de quebrar o elo entre crescimento económico e os impactos ambientais associados à produção de resíduos, são implementadas, nos países com elevados níveis de desenvolvimento, políticas baseadas em modelos integrados de gestão de RU que permitem a recuperação, reciclagem e valorização dos materiais, reservando-se a eliminação (deposição em aterro) para frações não valorizáveis, o que gera empregos e riqueza. Em Portugal vigora o Plano Estratégico para os Resíduos Urbanos (PERSU 2020) que define objetivos e metas nacionais, nomeadamente a meta da recolha seletiva, estabelecendo para 2020 um quantitativo nacional mínimo a recuperar de 47 kg por habitante por ano. Deste modo, importa caracterizar, para o período de 2002 a 2012, como evoluiu a produção de RU em comparação com a evolução do PIB em Portugal. A análise foca-se então na produção de RU na região do Alentejo em particular no Alentejo Central que evidencia um elevado nível per capita em comparação com o resto do país, situando-se mesmo acima das regiões do grande Porto e Lisboa. São apresentadas possíveis razões para o registo destes elevados níveis de produção de RU não se conseguindo, no entanto, avançar com evidências. Como o modelo DEA é utilizado no PERSU 2020 para fundamentar a projeção das metas da recolha seletiva por sistema de gestão de resíduos urbanos, fez-se a sua reprodução, o que permitiu uma análise mais detalhada dos dados e o ensaio de novos resultados considerando, para além do nível de produção de RU, o numero de equipamentos de deposição de recolha seletiva como input do modelo; Abstract: Title of the report: Professional career. Emphasis on the analysis of urban waste production in Alentejo Central - Portugal and the use of the DEA in defining the separate collection target This professional report presents the theme of the Urban Waste (UW) production in Central Alentejo, using the DEA (Data Envelopment Analysis) to analyse the target set for selective collection in 2020. Generally, the higher the degree of economic development of a region, the greater the rate of urbanization and the greater also the amount of municipal waste produced per capita. The variables income and urbanization are highly correlated, if you have an increase in the disposable income and living standards, the consumption of goods and services will increase accordingly, which leads to the increase of the amount of produced waste. Thus, taking into account the local impact that the abandoned UW brings, and in order to break the link between economic growth and the environmental impacts associated with the production of waste, countries with high levels of development implement policies based on integrated UW management models that allow the recovery, recycling and valorisation of materials, restricting the disposal (landfill) to non-recoverable fractions, which creates jobs and wealth. Portugal established a national strategic plan for Urban Waste (PERSU 2020) which defines the goals and national targets, including the selective collection target stating for 2020 a minimum recover of 47 kg per capita per year. Then it is relevant to characterize and compare the evolution of UW production and GDP in Portugal for the period 2002 to 2012. The analysis then focuses on the production of UW in Alentejo, particularly in Central Alentejo region, which shows a high per capita level compared to the rest of the country, placed just above the Greater Porto and Lisbon region. Then we explore several possible reasons for this high level of UW production in this region, but none is successful in producing strong evidence. As the DEA is used in PERSU 2020 to support the projection of the selective collection targets for the municipal waste management systems, in this report we develop the model, which allowed access to the data and a more detailed analyse. Then we introduce and test a new input, the number of separate collection deposition equipment, which gives new results that are compared with the original ones.

The Use of Agricultural and Logging Waste as Litter Materials in Broiler Rearing

A research has been conducted to study the use of agricultural and logging waste as litter materials in broiler rearing. Experimental method was used with completely randomized design. The treatments were the use of agricultural and logging waste as litter materials (L) consisting of L1 = rice hulls, L2 = rice straw, L3 = wood draff and L4 = saw dust. Parameters observed were litter moisture, production index and income over feed and litter cost (IOFLC). The experiment used 96 chickens, which were divided, into 24 cages. Statistical analysis showed that the use of agricultural and logging waste significantly (P<0,01) affected the litter moisture, production index and IOFLC. It could be concluded that rice straw, small plane wood and saw dust could be used as litter materials in broiler rearing.

The effect of Strain and Altitude on Broiler Performance

The research aimed to study the effect of strain and altitude on broiler performance, and to find out suitable strains kept either on low and high altitude. Low altitude was in Purwonegoro North Purwokerto (80 m asl) and high altitude was in Munggangsari Baturaden (755 m asl). The research was carried out since September 5th to December 5th, 1996 using 2x3 Factorial based on Completely Randomized Design. Factor I were land altitude (d) : low (d1) and high (d2). Factor II were broiler strains (g) : CP-707 (g1), AS-101 (g2) and Lohmann (g3). Data obtained were analyzed using F test continued  to Least Significant Difference Test. The research indicated that interaction between altitude and strains significantly affected  feed convertion and income over feed  and doc cost, while strain had significant effect on feed convertion. AS-101 and Lohmann strains  kept on low altitude had the highest final weight. The low altitude gave better feed convertion and income over feed and doc cost, whereas CP-707 strain had the best feed convertion.

Ratio of Native Grass and Concentrate in the Ration to the Quality of Milk Production of Holstein Cow

The research attempted to find out ratio of native grass and concentrate in the ration to the quality of milk production of Holstein cow. Latin Square Design was used with five treatments of ratio of native grass and concentrate ( 70 : 30%, 60 : 40%, 50 : 50%, 40 : 60%, 30 : 70%), applied using five Holstein cows at the third lactation periode and the third mounth of lactation. The variable measured were in the quality milk production consist of actual milk yield, the milk fat content, crude protein, solid non fat, efficiency of  energy bruto and energy netto, and income over feed cost. The best ratio of native grass and concentrate in the ration for the efficiency of energy bruto, energy netto and income was 50 : 50%. The milk fat content and actual milk yield have relationship form with the milk energy value. The best ratio of native grass and concentrate in the ration to increasing the milk fat content, crude protein and crude of solid non fat was 70 : 30%.

Drivers of technology substitution : successive generations of high tech products

Principal Topic High technology consumer products such as notebooks, digital cameras and DVD players are not introduced into a vacuum. Consumer experience with related earlier generation technologies, such as PCs, film cameras and VCRs, and the installed base of these products strongly impacts the market diffusion of the new generation products. Yet technology substitution has received only sparse attention in the diffusion of innovation literature. Research for consumer durables has been dominated by studies of (first purchase) adoption (c.f. Bass 1969) which do not explicitly consider the presence of an existing product/technology. More recently, considerable attention has also been given to replacement purchases (c.f. Kamakura and Balasubramanian 1987). Only a handful of papers explicitly deal with the diffusion of technology/product substitutes (e.g. Norton and Bass, 1987: Bass and Bass, 2004). They propose diffusion-type aggregate-level sales models that are used to forecast the overall sales for successive generations. Lacking household data, these aggregate models are unable to give insights into the decisions by individual households - whether to adopt generation II, and if so, when and why. This paper makes two contributions. It is the first large-scale empirical study that collects household data for successive generations of technologies in an effort to understand the drivers of adoption. Second, in comparision to traditional analysis that evaluates technology substitution as an ''adoption of innovation'' type process, we propose that from a consumer's perspective, technology substitution combines elements of both adoption (adopting the new generation technology) and replacement (replacing the generation I product with generation II). Based on this proposition, we develop and test a number of hypotheses. Methodology/Key Propositions In some cases, successive generations are clear ''substitutes'' for the earlier generation, in that they have almost identical functionality. For example, successive generations of PCs Pentium I to II to III or flat screen TV substituting for colour TV. More commonly, however, the new technology (generation II) is a ''partial substitute'' for existing technology (generation I). For example, digital cameras substitute for film-based cameras in the sense that they perform the same core function of taking photographs. They have some additional attributes of easier copying and sharing of images. However, the attribute of image quality is inferior. In cases of partial substitution, some consumers will purchase generation II products as substitutes for their generation I product, while other consumers will purchase generation II products as additional products to be used as well as their generation I product. We propose that substitute generation II purchases combine elements of both adoption and replacement, but additional generation II purchases are solely adoption-driven process. Extensive research on innovation adoption has consistently shown consumer innovativeness is the most important consumer characteristic that drives adoption timing (Goldsmith et al. 1995; Gielens and Steenkamp 2007). Hence, we expect consumer innovativeness also to influence both additional and substitute generation II purchases. Hypothesis 1a) More innovative households will make additional generation II purchases earlier. 1 b) More innovative households will make substitute generation II purchases earlier. 1 c) Consumer innovativeness will have a stronger impact on additional generation II purchases than on substitute generation II purchases. As outlined above, substitute generation II purchases act, in part like a replacement purchase for the generation I product. Prior research (Bayus 1991; Grewal et al 2004) identified product age as the most dominant factor influencing replacements. Hence, we hypothesise that: Hypothesis 2: Households with older generation I products will make substitute generation II purchases earlier. Our survey of 8,077 households investigates their adoption of two new generation products: notebooks as a technology change to PCs, and DVD players as a technology shift from VCRs. We employ Cox hazard modelling to study factors influencing the timing of a household's adoption of generation II products. We determine whether this is an additional or substitute purchase by asking whether the generation I product is still used. A separate hazard model is conducted for additional and substitute purchases. Consumer Innovativeness is measured as domain innovativeness adapted from the scales of Goldsmith and Hofacker (1991) and Flynn et al. (1996). The age of the generation I product is calculated based on the most recent household purchase of that product. Control variables include age, size and income of household, and age and education of primary decision-maker. Results and Implications Our preliminary results confirm both our hypotheses. Consumer innovativeness has a strong influence on both additional purchases (exp = 1.11) and substitute purchases (exp = 1.09). Exp is interpreted as the increased probability of purchase for an increase of 1.0 on a 7-point innovativeness scale. Also consistent with our hypotheses, the age of the generation I product has a dramatic influence for substitute purchases of VCR/DVD (exp = 2.92) and a strong influence for PCs/notebooks (exp = 1.30). Exp is interpreted as the increased probability of purchase for an increase of 10 years in the age of the generation I product. Yet, also as hypothesised, there was no influence on additional purchases. The results lead to two key implications. First, there is a clear distinction between additional and substitute purchases of generation II products, each with different drivers. Treating these as a single process will mask the true drivers of adoption. For substitute purchases, product age is a key driver. Hence, implications for marketers of high technology products can utilise data on generation I product age (e.g. from warranty or loyalty programs) to target customers who are more likely to make a purchase.

Best Practice Guide : Generic Overview

The construction industry is a key national economic component. It tends to be at the forefront of cyclic changes in the Australian economy. It has a significant impact, both directly and indirectly, on the efficiency and productivity of other industries. Moreover it affects everyone to a greater or lesser extent; through its products whether they are manifested in the physical infrastructure that supports the operation of the economy or through the built environment that directly impacts on the quality of life experienced by individuals. In financial terms the industry makes one of the largest contributions to the Australian economy, accounting for 4.7 per cent of GDP 1 which was worth over $30B in 20012. The construction industry is comprised of a myriad of small firms, across several important sectors including, o Residential building, o Commercial building, o Building services, o Engineering, o Infrastructure o Facilities Management o Property Development Each sector is typified by firms that have distinctive characteristics such as the number of employees, size and value of contracts, number of jobs, and so forth. It tends to be the case that firms operating in commercial building are larger than those involved in residential construction. The largest contractors are found in engineering and infrastructure, as well as in the commercial building sub-sectors. However all sectors are characterised by their reliance upon sub-contractors to carry out on-site operations. Professionals from the various design consultant groups operate across all of these sectors. This description masks one of the most significant underlying causes of inefficiency in the construction industry, namely its fragmentation. The Construction Industry chapter of the 2004 Australian Year Book3, published by the Australian Bureau of Statistics unmasks the industry’s fragmented structure, typified by the large number of operating businesses within it, the vast majority of which are small companies employing less than 5 people. It identifies over 190,000 firms, of which over 90 percent employ less than 5 people. At the other end of the spectrum, firms employing 20 or more people account for fractionally more than one percent of businesses in the industry.

Total rural land performance in a free trade economy

The importance of agriculture in many countries has tended to reduce as their economies move from a resource base to a manufacturing industry base. Although the level of agricultural production in first world countries has increased over the past two decades, this increase has generally been at a less significant rate compared to other sectors of the economies. Despite this increase in secondary and high technology industries, developed countries have continued to encourage and support their agricultural industries. This support has been through both tariffs and price support. Following pressure from developing economies, particularly through the World Trade Organisation (WTO), GATT Uruguay round and the Cairns Group Developed countries are now in various stages of winding back or de-coupling agricultural support within their economies. A major concern of farmers in protected agricultural markets is the impact of a free market trade in agricultural commodities on farm incomes and land values. This paper will analyse the capital and income performance of the NSW rural land market over the period 1990-1999. This analysis will be based on land use and will compare the total return from rural properties based on world agricultural commodity prices.

Drivers of adoption for successive generation of high-tech products

To understand the diffusion of high technology products such as PCs, digital cameras and DVD players it is necessary to consider the dynamics of successive generations of technology. From the consumer’s perspective, these technology changes may manifest themselves as either a new generation product substituting for the old (for instance digital cameras) or as multiple generations of a single product (for example PCs). To date, research has been confined to aggregate level sales models. These models consider the demand relationship between one generation of a product and a successor generation. However, they do not give insights into the disaggregate-level decisions by individual households – whether to adopt the newer generation, and if so, when. This paper makes two contributions. It is the first large scale empirical study to collect household data for successive generations of technologies in an effort to understand the drivers of adoption. Second, in contrast to traditional analysis in diffusion research that conceptualizes technology substitution as an “adoption of innovation” type process, we propose that from a consumer’s perspective, technology substitution combines elements of both adoption (adopting the new generation technology) and replacement (replacing generation I product with generation II). Key Propositions In some cases, successive generations are clear “substitutes” for the earlier generation (e.g. PCs Pentium I to II to III ). More commonly the new generation II technology is a “partial substitute” for existing generation I technology (e.g. DVD players and VCRs). Some consumers will purchase generation II products as substitutes for their generation I product, while other consumers will purchase generation II products as additional products to be used as well as their generation I product. We propose that substitute generation II purchases combine elements of both adoption and replacement, but additional generation II purchases are solely adoption-driven process. Moreover, drawing on adoption theory consumer innovativeness is the most important consumer characteristic for adoption timing of new products. Hence, we hypothesize consumer innovativeness to influence the timing of both additional and substitute generation II purchases but to have a stronger impact on additional generation II purchases. We further propose that substitute generation II purchases act partially as a replacement purchase for the generation I product. Thus, we hypothesize that households with older generation I products will make substitute generation II purchases earlier. Methods We employ Cox hazard modeling to study factors influencing the timing of a household’s adoption of generation II products. A separate hazard model is conducted for additional and substitute purchases. The age of the generation I product is calculated based on the most recent household purchase of that product. Control variables include size and income of household, age and education of decision-maker. Results and Implications Our preliminary results confirm both our hypotheses. Consumer innovativeness has a strong influence on both additional purchases and substitute purchases. Also consistent with our hypotheses, the age of the generation I product has a dramatic influence for substitute purchases of VCR/DVD players and a strong influence for PCs/notebooks. Yet, also as hypothesized, there was no influence on additional purchases. This implies that there is a clear distinction between additional and substitute purchases of generation II products, each with different drivers. For substitute purchases, product age is a key driver. Therefore marketers of high technology products can utilize data on generation I product age (e.g. from warranty or loyalty programs) to target customers who are more likely to make a purchase.

Adult learning in a workplace context

In light of the changing nature of contemporary workplaces, this chapter attempts to identify employer expectations and the associated skills required to workers to function effectively in such workplaces. Workers are required to participate in informed discussion about their specific jobs and to contribute to the overall development of organisations. This requires deep understanding of domain-specific knowledge, which at times can be very complex. Workers are also required to take responsibility for their actions and are expected to be flexible so that they can be deployed to other related jobs depending on demand. Finally, workers are expected to be pro-active, be able to anticipate situations and continuously update their knowledge to address new situations. This chapter discusses the nature of knowledge and skills that will facilitate the above qualities.
