Scale architecture of the palmar and plantar epidermis of Polychrus acutirostris Spix, 1825 (Iguania, Polychrotidae) and its relationship to arboreal locomotion

In tetrapod squamates, the diversity of micro-ornamentations of the epidermis of the contact areas of hands and feet is generally associated with constraints and modalities related to locomotion. Polychrus acutirostris is a medium-sized lizard that occurs in open heterogeneous habitats in South America, such as the cerrados, caatingas, and fallow lands. It progresses slowly on branches of various diameters in its arboreal environment. It can also move more rapidly on the ground. The hands and feet are prehensile and may be considered an adaptation for grasping and climbing. Epidermal surfaces from the palmar and plantar areas of the hands and feet of P. acutirostris were prepared for SEM examination, and studied at various magnifications. They show three major levels of complexity: (1) scale types, organized in gradients of size and imbrication, (2) scalar ornamentations, organized by increasing complexity and polarity, and (3) presence of Oberhautchen showing typically iguanian honeycomb micro-ornamentations. The shape and surface structure of the scales with their pattern of micro-ornamental peaks, which improve grip, and the grasping hands and feet indicate that P. acutirostris is morpho-functionally specialized for arboreality.

Chromosomal Evolution in the Brazilian Geckos of the Genus Gymnodactylus (Squamata, Phyllodactylidae) from the Biomes of Cerrado, Caatinga and Atlantic Rain Forest: Evidence of Robertsonian Fusion Events and Supernumerary Chromosomes

Chromosomes of the South American geckos Gymnodactylus amarali and G. geckoides from open and dry areas of the Cerrado and Caatinga biomes in Brazil, respectively, were studied for the first time, after conventional and AgNOR staining, CBG- and RBG-banding, and FISH with telomeric sequences. Comparative analyses between the karyotypes of open areas and the previously studied Atlantic forest species G. darwinii were also performed. The chromosomal polymorphisms detected in populations of G. amarali from the states of Goias and Tocantins is the result of centric fusions (2n = 38, 39 and 40), suggesting a differentiation from a 2n = 40 ancestral karyotype and the presence of supernumerary chromosomes. The CBG- and RBG-banding patterns of the Bs are described. G. geckoides has 40 chromosomes with gradually decreasing sizes, but it is distinct from the 2n = 40 karyotypes of G. amarali and G. darwinii due to occurrence of pericentric inversions or centromere repositioning. NOR location seems to be a marker for Gymnodactylus, as G. amarali and G. geckoides share a medium-sized subtelocentric NOR-bearing pair, while G. darwinii has NORs at the secondary constriction of the long arm of pair 1. The comparative analyses indicate a non-random nature of the Robertsonian rearrangements in the genus Gymnodactylus. Copyright (C) 2010 S. Karger AG, Basel

Besökshundens påverkan på arbetssituationen inom den särskilda omsorgen

This essay is about dogs that visit is used, whitin care of elderly. The dogs found caretakers once a week and one hour at a time. The focus has been placed on the dogs that go to the municipality's special accommodation and the research was done in a medium-sized municipality in Sweden. The focus of the narrowing of the work was done to the work situation for care staff to assess the impact of the visits the dogs presence. It was distributed questionnaires answered by care staff in which it concluded their visit to the dog's presence felt and how it impacted the situation. There has been much previous research done on how dogs affect the elderly in care. This has been done to see if the care staff perceive the same thing, and in turn experience any possible help of visiting dogs. What emerged in this study is that most are in favor of visits dog and they're older. The majority of respondents agreed that their work situation has become neither better nor worse then visit the dogs started to meet caretakers. This may be due to visit the dog is not enough time on site at each visit. Even the fact that care staff are not practicing with the caretakers memory to get them to remain in the state of mind that research shows that the older gets in. These can have an impact on how care staff perceive a possible means in visits of the dog.

Arbetsorganisation i träbränsleeldande fjärrvärmeverk

The objective of this study has been to describe and analyse existing forms of organisation in heating plants using wood fuels, regarding work tasks, organisational structure, skill demands, crew recruitment, working hours and wage conditions. Sixteen plants ranging from 10 to 120 MW have been studied by means of interviews, work place observations and written material. The job of the operator of heating plants is fairly qualified, independent and varied. The most negative factor is shift work. Some of the bigger plants (enterprises) have a relatively hierarchic, segmented and perhaps also an oversized organisation. However, modern concepts of organisation, such as customer orientation, ”flat organisation”, integration of production and maintenance etc, are gaining ground. Blue collar and white collar tasks are increasingly being integrated. Some of the medium sized enterprises have reached very far and may serve as models for bigger enterprises.

Change in Managers’ Conceptions of Human Resources in Organisations : Outcomes of an Intervention

Managers’ conceptions of the importance of human resources are essential for creating ‘attractive workplaces’. This paper examines an intervention method aimed at creating insight among managers in small and medium-sized enterprises (SMEs) concerning the potential of human resources. The intervention method is called Focus Group Attractive Work (FGAW) and was conducted at eight enterprises in Sweden. Based on the analysis, it is concluded that the intervention method seems to be thought-provoking and to facilitate changes in managers’ conceptions of the importance of human resources, albeit to different degrees. 

Generationsväxling i offentlig sektor : En kvalitativ studie om det kommunala arbetet medpensionsavgångar

Denna studie syftar till att undersöka hur en medelstor kommun kan arbeta strategiskt med problematiken gällande kompetensförlust samt att vara en attraktiv arbetsgivare inför kommande pensionsavgångar. Vidare syftar studien till att, utifrån resultatet, arbeta fram ett förslag till HR-strategi för den problematik de förestående pensionsavgångarna för med sig. För att få svar på våra undersökningsfrågor har vi utfört en fallstudie i Falu kommun och för denna använt oss av semistrukturerade intervjuer med fyra personer i chefsposition och en mångfaldskommunikatör, samt en fokusgrupp bestående av fyra medarbetare från HR-avdelningen. Detta gav oss flera perspektiv på problematiken, vilket vi anser stärker tillförlitligheten i resultatet. I efterhand kan vi dock se att ett större antal intervjupersoner hade varit att föredra, detta för att få fler medarbetares tankar och åsikter om ämnet. Emellertid var detta inte möjligt då chefer i kommunen var svåra att få kontakt med.Resultatet visar att uppfattningen om pensionsavgångar är varierande då en av respondenterna menar att det inte är något att oroa sig över, medan övriga respondenter anser att det är en stor utmaning kommunen har framför sig. Resultatet visar även att Falu kommun i dagsläget arbetar strategiskt med ett flertal olika åtgärder för att stärka sitt arbetsgivarmärke externt såsom exempelvis ambassadörskap och talent management, vilket tidigare forskning visar är en nödvändighet för en organisations konkurrenskraft och således attrahera samt behålla medarbetare. Gällande kompetensöverföring visar resultatet att det idag finns en medvetenhet om riskerna för kompetensförluster. Dock utförs ett begränsat arbete för att överföra viktiga kompetenser, åtminstone med syfte att hantera den risk för kompetensförlust som väntas i och med den förestående generationsväxlingen. Tidigare forskning inom området pensionsavgångar visar dock att förlusten av viktiga kompetenser är det största hotet.Vår slutsats av denna studie är att Falu kommun är på rätt väg att hantera den problematik som förväntas uppstå, dock behöver kommunen öka medvetenheten genom kommunikation och intern marknadsföring samt arbeta samman en gemensam syn på pensionsavgångarna i alla förvaltningar. Vi menar även att det är av stor vikt att se över kompetenserna i organisationen och börja agera för att inte mista viktiga kompetenser i och med de förestående pensionsavgångarna. Detta är områden som behandlas i det förslag till HR-strategi vi har arbetat fram.

Strategic alliances in a town centre : Stakeholder’s perceptions of property owner’s role

In order for town centres to manage increased competition in retailing, co-operation between stakeholders in a strategic alliance has become more important. A typical set of stakeholders in a strategic alliance for strengthening retailingare retailers, local authorities and property owners. The roles of retailer’sand local authorities’ are well researched. However, the role of property owners is not. The aim of this paper seeks to unfold the role of property owners in a strategic alliance. This is a case study of a medium-sized town in which semi-structured interviews with different stakeholders were conducted. In the chosen town there is a TCM alliance co-operation at work. The above mentioned stakeholders are possible members in an alliance. The case studied shows a fragmented property owner market with no dominant property owner, as it is in many medium-sized towns. Our study shows that many stakeholders look at the role of property owners as crucial for town centre development. However, property owners do not see that they can significantly contribute to or benefit from the development.The main reasons for this opinion are that they consider themselves as not having enough resources or the capability to influence the town development.

Projekt Norrliden : Om småstadspressens etnifiering och genderisering av en förort

The Norrliden project. Genderisation and ethnification of a low status residential area in the local press Media often contributes to segregation by constructing low status residential areas as “different” from what is “normal” and “Swedish”. Research into media representations of these residential areas often focuses big city contexts. Furthermore, research tends to be preoccupied with the construction of ethnic differences, paying little attention to the relationship between construction processes of gender and ethnicity. This article is a critical analysis of how the local daily newspapers in a medium sized town, Kalmar, construct stereotypes of immigrants and gendered identities in the low status residential area Norrliden. Two newspapers were studied in search for articles related to the area, published during the year 2005. Despite the newspapers’ claim that they want to contribute to a more nuanced and less stereotyped image of the residential area the consequences of their work seem to be the opposite. The representation sof the area are coded with stereotypes suggesting that the area is unsafe and dangerous and that the people who live there are motivated by affect and emotions rather than by successful socialisation. These representations are also characterised by notions of ethnicity and gender, as well as class. Norrliden is described as an area in need of change and improvement, as an unfinished project dependent upon aid from the outside. A reading of the 2005 media representations of Norrliden exposes an example of “symbolic violence” in that texts and photographs repeatedly degrade the area and its inhabitants.

Barriers to adapt eCommerce by rural microenterprises in Sweden : a case study

Research has shown that small and medium-sized enterprises (SMEs) are rapidly adopting the e-commerce. However, there is nearly no research into how microenterprises are adopting eCommerce. Present paper focus on microenterprise adaption of eCommerce in terms of barriers in relation to already known research on SMEs. A case study, carried out by 12 microenterprises to find out barriers to adapt eCommerce had been done. The empirical results show that the microenterprises share most of the barriers to adapt the eCommerce with studies of SMEs, but also reveal additional factors affecting adaptation option of eCommerce; supplier agreement, communication and customer strategy. Conclusions are that microenterprises need additional support and communication and customer strategy to adapt eCommerce, depending of their requirement and needs of eCommerce.

Demonstration of Solar Heating and Cooling System using Sorption Integrated Solar Thermal Collectors

Producing cost-competitive small and medium-sized solar cooling systems is currently a significant challenge. Due to system complexity, extensive engineering, design and equipment costs; the installation costs of solar thermal cooling systems are prohibitively high. In efforts to overcome these limitations, a novel sorption heat pump module has been developed and directly integrated into a solar thermal collector. The module comprises a fully encapsulated sorption tube containing hygroscopic salt sorbent and water as a refrigerant, sealed under vacuum with no moving parts. A 5.6m2 aperture area outdoor laboratory-scale system of sorption module integrated solar collectors was installed in Stockholm, Sweden and evaluated under constant re-cooling and chilled fluid return temperatures in order to assess collector performance. Measured average solar cooling COP was 0.19 with average cooling powers between 120 and 200 Wm-2 collector aperture area. It was observed that average collector cooling power is constant at daily insolation levels above 3.6 kWhm-2 with the cooling energy produced being proportional to solar insolation. For full evaluation of an integrated sorption collector solar heating and cooling system, under the umbrella of a European Union project for technological innovation, a 180 m2 large-scale demonstration system has been installed in Karlstad, Sweden. Results from the installation commissioned in summer 2014 with non-optimised control strategies showed average electrical COP of 10.6 and average cooling powers between 140 and 250 Wm-2 collector aperture area. Optimisation of control strategies, heat transfer fluid flows through the collectors and electrical COP will be carried out in autumn 2014.

Swedish Primary Teachers' Attitudes towards Integrating Gaming in the EFL Classroom

A current topic in Swedish schools is the use of computer games and gaming. One reason is because computers are becoming more and more integrated into the schools, and the technology plays a large role in the everyday lives of the pupils. Since teachers should integrate pupils’ interests in the formal teaching, it is of interest to know what attitudes teachers have towards gaming. Therefore the aim of this empirical study is to gain an insight into the attitudes Swedish primary teachers have towards online and offline computer games in the EFL classroom. An additional aim is to investigate to what extent teachers use games. Five interviews were conducted with teachers in different Swedish schools in a small to medium-sized municipality. After the interviews were transcribed, the results were analyzed and discussed in relation to relevant research and the sociocultural theory. The results show that teachers are positive towards games and gaming, mostly because gaming often contains interaction with others and learning from peers is a main component in sociocultural theory. However, only one out of the five participants had at some point used games. The conclusion is that teachers are unsure about how to use games in their teaching and that training and courses in this area would be valuable. More research is needed within this area, and it would be of value to investigate what suggested courses would contain and also to investigate exactly how games can be used in teaching.

Resan till samhället : En kvalitativ utvärderingsstudie av en mottagningsenhet i mellansverige

In present study interviews with five officials and the gathering of documentation carried out in a reception center for newly arrived refugees located in a medium-sized municipality in central Sweden. The aim has been on the basis of the collected empirical data to evaluate how the municipality worked to promote the integration of newcomers, what measures were available, whether there were existing goals, and how they were formulated, and the extent to which they were implemented. This constituted, together with earlier research and systems theory based framework for the study's conclusions. The study showed that communication between and within the investigated unit was partly flawed. It has also showed that there was a degree of conflict in organizational approaches within the examined entity which could cause bottlenecks in the activity. The current study also showed the difficulty in estimating the resources currently needed to cover the need of, among others, Swedish for immigrants.

Estudo dos gastos e investimentos em informática: avaliação, evolução e tendências nas médias e grandes empresas

"Estudo dos Gastos e Investimentos em Informática" - Estudo que quantifica os gastos e investimentos em informática e analisa a sua evolução nos últimos dez anos para identificar seu comportamento e suas tendências. os valores são estudados por meio de dois índices: o gasto total (investimentos e despesas) como uma percentagem do faturamento líquido da empresa e o custo anual por teclado. Ambos são indicadores oumedidas com um uso crescente e que podem ter umpapel fundamental na moderna administração da tecnologia da Informação. Os dados levantados vão até o início de 1999 para 1.141 empresas médias e grandes que atuam no Brasil. O estudo retrata a evolução, analisa o comportamento e demonstra que os índices dependem do setor da economia e do nível de informatização da empresa.
