Behavioral suites mediate group-level foraging dynamics in communities of tropical stingless bees

Competition for floral resources is a key force shaping pollinator communities, particularly among social bees. The ability of social bees to recruit nestmates for group foraging is hypothesized to be a major factor in their ability to dominate rich resources such as mass-flowering trees. We tested the role of group foraging in attaining dominance by stingless bees, eusocial tropical pollinators that exhibit high diversity in foraging strategies. We provide the first experimental evidence that meliponine group foraging strategies, large colony sizes and aggressive behavior form a suite of traits that enable colonies to improve dominance of rich resources. Using a diverse assemblage of Brazilian stingless bee species and an array of artificial ""flowers"" that provided a sucrose reward, we compared species` dominance and visitation under unrestricted foraging conditions and with experimental removal of group-foraging species. Dominance does not vary with individual body size, but rather with foraging group size. Species that recruit larger numbers of nestmates (Scaptotrigona aff. depilis, Trigona hyalinata, Trigona spinipes) dominated both numerically (high local abundance) and behaviorally (controlling feeders). Removal of group-foraging species increased feeding opportunities for solitary foragers (Frieseomelitta varia, Melipona quadrifasciata and Nannotrigona testaceicornis). Trigona hyalinata always dominated under unrestricted conditions. When this species was removed, T. spinipes or S. aff. depilis controlled feeders and limited visitation by solitary-foraging species. Because bee foraging patterns determine plant pollination success, understanding the forces that shape these patterns is crucial to ensuring pollination of both crops and natural areas in the face of current pollinator declines.

First evidence of insect attraction by a Southern Hemisphere Splachnaceae: The case of Tayloria dubyi Broth. in the Reserve Biosphere Cape Horn, Chile

The moss Tayloria dubyi (Splachnaceae) is endemic to the subantarctic Magallanes ecoregion where it grows exclusively on bird dung and perhaps only on feces of the goose Chloephaga picta, a unique habitat among Splachnaceae. Some species of Splachnaceae from the Northern Hemisphere are known to recruit coprophilous flies as a vector to disperse their spores by releasing intense odors mimicking fresh clung or decaying corpses. The flies land on the capsule, and may get in contact with the protruding mass of spores that stick to the insect body. The dispersal strategy relies on the spores falling off when the insect reaches fresh droppings or carrion. Germination is thought to be rapid and a new population is quickly established over the entire substrate. The objectives of this investigation were to determine whether the coprophilous T. dubyi attracts flies and to assess the taxonomic diversity of the flies visiting this moss. For this, fly traps were set up above mature sporophyte bearing populations in two peatlands on Navarino Island. We captured 64 flies belonging to the Muscidae (Palpibracus chilensis), Tachinidae (Dasyuromyia sp) and Sarcophagidae (not identified to species) above sporophytes of T. dubyi, whereas no flies were captured in control traps set up above Sphagnum mats nearby.

Nop53p interacts with 5.8S rRNA co-transcriptionally, and regulates processing of pre-rRNA by the exosome

In eukaryotes, pre-rRNA processing depends on a large number of nonribosomal trans-acting factors that form intriguingly organized complexes. One of the early stages of pre-rRNA processing includes formation of the two intermediate complexes pre-40S and pre-60S, which then form the mature ribosome subunits. Each of these complexes contains specific pre-rRNAs, ribosomal proteins and processing factors. The yeast nucleolar protein Nop53p has previously been identified in the pre-60S complex and shown to affect pre-rRNA processing by directly binding to 5.8S rRNA, and to interact with Nop17p and Nip7p, which are also involved in this process. Here we show that Nop53p binds 5.8S rRNA co-transcriptionally through its N-terminal region, and that this protein portion can also partially complement growth of the conditional mutant strain Delta nop53/GAL:NOP53. Nop53p interacts with Rrp6p and activates the exosome in vitro. These results indicate that Nop53p may recruit the exosome to 7S pre-rRNA for processing. Consistent with this observation and similar to the observed in exosome mutants, depletion of Nop53p leads to accumulation of polyadenylated pre-rRNAs.

Defective transcription/repair factor IN recruitment to specific UV lesions in trichothiodystrophy syndrome

Most trichothiodystrophy (TTD) patients present mutations in the xeroderma pigmentosum D (XPD) gene, coding for a subunit of the transcription/repair factor IIH (TFHH) complex involved in nucleotide excision repair (NER) and transcription. After UV irradiation, most TTD/XPD patients are more severely affected in the NER of cyclobutane pyrimidine dimers (CPD) than of 6-4-photoproducts (6-4PP). The reasons for this differential DNA repair defect are unknown. Here we report the first study of NER in response to CPDs or 6-4PPs separately analyzed in primary fibroblasts. This was done by using heterologous photorepair; recombinant adenovirus vectors carrying photolyases enzymes that repair CPD or 64PP specifically by using the energy of light were introduced in different cell lines. The data presented here reveal that some mutations affect the recruitment of TFHH specifically to CPDs, but not to 6-4PPs. This deficiency is further confirmed by the inability of TTD/XPD cells to recruit, specifically for CPDs, NER factors that arrive in a TFIIH-dependent manner later in the NER pathway. For 6-4PPs, we show that TFHH complexes carrying an NH2-terminal XPD mutated protein are also deficient in recruitment of NER proteins downstream of TFUH. Treatment with the histone deacetylase inhibitor trichostatin A allows the recovery of TFHH recruitment to CPDs in the studied TTD cells and, for COOH-terminal XPD mutations, increases the repair synthesis and survival after UV, suggesting that this defect can be partially related with accessibility of DNA damage in closed chromatin regions.

Materialundersökning

This report emphasizes the importance of seeing a university as a company that offers a service. It isimportant to see the different quality dimensions that distinguish a service. The customer-focused planninghas also set the structure of this degree project.The marketing investigation is based on recruit questionnaires and interviews with secondary schoolstudents. The questionnaires show that the catalogue still reaches out with most information despiteconstant increase of information search at the Internet. The students seem to prefer University ofKristianstad´s catalogue front.The competition analysis is based on telephone interviews and information material sent from theother universities. Structure, usage of the graphic profile amongst more is reviewed for every university.The answers have varied a lot but there are few that have a good structure. University of Dalarna´sinformation material has neither structure nor a homogenous look.The employees at University of Dalarna are not using the universities graphic profile. They are alsodissatisfied regarding the absence of pre-produced, general overhead film series. The internal analysisalso shows that the employees don’t know which material is accessible or where to find it.

Attractive Work Process

Many companies both in Sweden and other parts of the world are since the beginning of the 21st century faceing a lack of work force (1,2,3). The ability to recruit and retain skilled employees is seen as one of the most important questions for the survival and development of the companies (4,5). Labour shortage is seen as the biggest obstacle for expansion for small enterprises in Sweden (5). There is a need for workplaces to be attractive, but how can the attractiveness be increased? Researchers at Högskolan Dalarna have during almost a decennium conducted research concerning attractive work. Based on a modell of qualities that contributes to make a work attractive (6) has a method aiming for raised attractiveness been developed for SME:s. All employees participate by answering a questionnaire about the importance of different qualities and to what degree they are fulfilled. Further discussions at the workplace on what to preserve and what to develop make the base for an action plan.Important experiences:• Discuss and establish the aim of the method with management and employees. • The company must be prepared to follow up and realize the action plan.• Agree about expectations – they must be realistic and practicable.• Reserve time to start the process and to end up in an action plan. • Avoid negative thinking and put problems away. • Take all the time small steps in the right direction.• Keep employees engaged and avoid the manager or process leader to take the command.• Use the strategy with small work groups; it gives better possibilities for participation and outspokenness.• Follow up studies are necessary to keep up the motivation.The most positive aspects of the method is its promoting perspective and that it engages all the employees.1.Rauhut, D.

Ökad förståelse bland företagsledare för nyttan av utvecklingsinsatser inom arbetsmiljöområdet

Sammanfattning Föreliggande rapport avser en delstudie inom projektet Attraktiv Konkurrenskraft (AKK) Syftet med detta arbete är att utvärdera fem metoder som kan ”väcka insikt” om nyttan av att starta utvecklingsaktiviteter för att bättre ta tillvara de mänskliga resurserna i arbetet. Baserat på detta ska en metod väljas för fördjupade studier. Drivkrafterna för att skapa bra arbetsmiljöer är många. Den primära kan sägas vara den humanitära drivkraften. Förutom de överväganden som ligger till grund för arbetsmiljölagstiftning och avtal mellan arbetsmarknadens parter finns alltså goda skäl för företagare att prioritera arbetsmiljöarbete. Den fråga som berörs i detta arbete är i vad mån det är möjligt att genom enkla insatser påverka en arbetsmiljöansvarig chefs benägenhet att gå till beslut om att genomföra insatser för att utveckla förutsättningarna för att bättre nyttja de mänskliga resurserna i organisationen. Målet är att chefen bestämmer sig för att påbörja en beslutsprocess om utvecklingsaktiviteter för att ta tillvara de mänskliga resurserna i arbetet vilket ökar förutsättningarna att rekrytera, behålla och engagera kompetent personal. Som resultat av förstudien har fem olika insiktsmetoder utvecklats och anpassats. Dessa metoder har kallats GAP-analys, Fokusgrupper Attraktivt Arbete, Visit, Riskanalys och Scenario. De tio företagen som deltog hade mellan 11 och 39 anställda, och deras verksamheter var inom områdena tillverkning, reparation och underhåll. Resultat från användning av metoderna visar att alla metoderna uppfyller kriterierna att vara enkla att förstå och snabba att genomföra. Fokusgrupper, Visit och Riskanalys ger konkret vägledning för fortsatt utvecklingsarbete. Fokusgrupper ger ett brett underlag för en fortsättning som bygger på dialog, en djupare analys på individnivå samt har psykiska och sociala dimensioner. Därmed sågs Fokusgrupper som den mest intressanta metoden att gå vidare med. Denna studie indikerar att det finns möjlighet att påverka ledare att ta beslut om aktiviteter för att utveckla den mänskliga resursen. Det finns därmed anledning att ytterligare studera ett antal företag där en och samma metod används. Valet har fallit på Fokusgrupper, även om andra metoder skulle vara tänkbara. Abstract This report concerns a sub-study of the project attractive competitiveness (AKK). The aim of the work is to evaluate five methods that are supposed to” raise awereness” about the advantages of initiating activities to better utilize human resources at work. Based on that shall one method be elected for depend studies. The driving forces for creation of good work environments are many. The primary can be said to be the humanitarian driving force. Except for the considerations that are behind the work environment legislations and agreements between social partners is therefore good reasons for entrepreneurs to give priority to work environment work. The focus of this study is to which extent it is possible by a limited input influence the liability of a manager with responsibilities for the work environment to take decisions to start a process aimed at improving the use of the human resources in the company. The goal is that the manager decides to start such a process which also is supposed to recruit, retain and engage competent staff. In the sub-study have five insight methods been developed or adapted. Those methods have been named gap-analysis, focus groups attractive work, visit, risk analysis, and scenario. The ten participating companies employed between eleven and thirty-nine persons. The companies represented different branches as production, repair work and maintenance. The results from the test of the methods shows that they all meet the criteria’s to be simple to understand and quick to carry through. Focus groups attractive work, visit, and risk analysis gives substantial guidance for further development work. Focus groups attractive work gives a broad base for a continuation built on a dialogue, a deeper analyses of individual level as well as mental and social dimensions. Of that reason chosen for deepened studies. This study indicates that there are possibilities to influence managers to decide about activities aimed at better use of human resources. There are therefore reasons to make further studies in a number of companies where the elected method is used.

Organisationer, ojämlikhet, migration : förändringar av den etniska arbetsdelningen i svensk byggnadssektor

Organizations, Inequality, Migration – Changes of the Ethnic Division of Labour in the Swedish Construction Sector During the 1990s the number of migrants from Eastern Europe increased in the Swedish construction sector. This article examines how this change was initiated by changes in the organizational population in the construction sector. The gradual enlargement of the European Union changed the institutional framework for organizations in Sweden. This created increased opportunities for new organizational forms in the construction sector. The specific niche of the new organizations was to recruit and hire out workers from Eastern Europe that were paid lower wages than Swedish workers. The diffusion of this organizational form contributed to a change of norms and beliefs about what was legitimate and illegitimate when employing migrants. This implies that the inequalities that this organizational form introduces have gained increased legitimacy in Sweden. Or in other words, it has become increasingly socially acceptable to pay migrants lower wages than Swedish workers

Attraktivt arbete i offentlig sektor bland enhetschefer inom vård och omsorg

HR-funktionens uppgift i en organisation är att tillvarata den mänskliga resursen och se till att goda arbetsförhållanden uppnås. Detta för att kunna attrahera, rekrytera, behålla och utveckla kompetens (Kira 2003). På senare år har arbetsförhållanden och arbetsvillkor uppmärksammats på kommuner i Sverige för bland annat enhetschefer i äldreomsorgen. Arbetsförhållandena, arbetsvillkoren och framför allt den höga personalomsättningen bland dessa, har lett till en problematik som var en av valets viktigaste frågor 2014. Syftet med denna studie är att beskriva arbetsförhållanden för enhetschefer inom mindre kommuner i Sverige, inom den sociala sektorn och belysa hur dessa skulle kunna förbättras. Som studieobjekt har Orsa kommun använts. Resultatet av undersökningen visade att arbetssituationen för enhetschefer är övermäktig, då det är hög arbetsbelastning samt dålig struktur i arbetet. Enhetscheferna själva skulle gynnas av en assistent samt en arbetsbeskrivning för att minska arbetsbelastningen och få struktur i arbetet. Vår slutsats är att kommuner i Sverige borde arbeta med att skapa bättre arbetsförhållanden för enhetschefer samt arbeta för att underlätta arbetsbördan. Vårt förslag till Orsa kommun är att ta hjälp av vår handlingsplan och därmed anställa assistenter till enhetscheferna samt skapa arbetsbeskrivningar. Vidare forskning i ämnet skulle kunna belysa mentorskapets betydelse i den offentliga sektorn inom kommuner i Sverige samt organisationsstrukturens bemärkelse för arbetets attraktivitet.

Rekrytering av kreatörer och portfolions betydelse : En enkätundersökning med femtio svenska kommunikationsbyråer

Inom kommunikationsbranschen råder det hög konkurrens om arbeten för både nyutexaminerade arbetssökande och de med erfarenhet. En viktig del i ansök-ningshandlingarna är en portfolio som visuellt visar personens kompetens och talang.Denna kvantitativa studie har genom en webbenkät med 50 byråer inom kom-munikationsbranschen undersökt hur de rekryterar ny personal samt deras per-spektiv kring portfolion i samband med detta. Studien har även syftat till att belysa skillnader i svaren beroende på byråernas storlek.Resultaten från enkäten visade att den vanligaste kanalen vid anställning inom kommunikationsbranschen är via personliga kontakter och att det är portfolions kvalité som väger tyngst vid anställning. Vid ansökan föredrog byråerna en digital portfolio men vid en arbetsintervju såg de helst en kombination av en fysisk och digital portfolio. Mindre skillnader fanns i svaren beroende på byrå-storleken.

Recruiting a Diverse Student Body at Mid-Size Public Master’s Universities

As student demographics change, admissions officers are increasingly recruiting a diverse group of incoming students, including underrepresented minorities. We outline how five public institutions identify and recruit potential applicants and review recruitment strategies and methodologies for expanding target recruitment populations.

Addressing Compensation Rates Below Market Value

Strategies for Recruiting and Retaining Faculty and Staff (Business Affairs Forum, attached): Many institutions face limitations on the salary rates they can offer faculty and staff due to decreases in state funding, which can create challenges in recruitment and retention of qualified employees. This brief explores strategies institutions use to lessen the impact of budget limitations on faculty and staff salaries and to recruit and retain faculty in spite of limited salary offerings.

Strategic Faculty Recruitment

As institutions strive to grow their research enterprises, selection and recruitment of faculty is critical. The Council presents strategies for determining a recruitment approach, selecting the appropriate level of faculty to recruit, and targeting specific faculty members. In addition, research explores practices for attracting faculty to the campus and supporting faculty through the transition.

Os professores públicos são mal remunerados nas escolas brasileiras? Uma análise da atratividade da carreira do magistério sob o aspecto da remuneração

Existe uma percepção generalizada de que os professores públicos brasileiros são mal remunerados. Dadas a relevância dos professores para o processo de ensino e a importância da remuneração como um incentivo à entrada, permanência e melhoria do desempenho de na carreira do magistério, o objetivo deste trabalho é avaliar a atratividade dos salários que os professores recebem nas escolas públicas de ensino básico brasileiras. Para tanto, foi utilizada a decomposição de Oaxaca (1973) aplicada aos dados da PNAD (Pesquisa Nacional por Amostra de Domicílios) para o período de 1995 a 2006 para calcular os diferenciais entre o salário desses professores públicos e os rendimentos que eles receberiam se estivessem em um dos seguintes grupos de comparação: demais ocupações do setor público, professores do setor privado e demais ocupações do setor privado. A análise indica que a atratividade da remuneração do magistério varia de acordo com o segmento de professores públicos comparados. Entre os principais resultados, obtivemos evidências que indicam que os professores com formação de nível médio possuem remunerações atrativas frente às demais ocupações, enquanto aqueles com formação de nível superior – justamente os que se quer atrair – encontram salários bem mais atrativos em ocupações alternativas. Além disso, dado o fato de homens conseguirem salários bem melhores que os das mulheres em ocupações alternativas, a remuneração do magistério é bem mais atrativa para mulheres que para homens. Por fim, obtivemos evidências de que a atratividade da remuneração de professores públicos é melhor para profissionais no início da carreira, mas pior para profissionais na etapa final da carreira – o que pode gerar abandono da carreira e prejudicar o desempenho desses professores. Deste modo, entende-se que os diversos resultados encontrados na análise segmentada da atratividade dos salários de professores públicos contribuem para o avanço na discussão de políticas salariais para o magistério para além de simples propostas de reajustes uniformes para toda a categoria.

Transformações no mercado de trabalho exigidas aos estagiários e recém-formados em empresas com características da sociedade pós-industrial

O objetivo desta dissertação é analisar até que ponto as transformações do mercado de trabalho, à luz da sociedade pós-industrial, interferem nas competências exigidas aos recém-formados e estagiários pelas empresas, quando da captação de seus recursos humanos, através do estudo de caso do CIEE - Centro de Integração Empresa-Escola. Os objetivos específicos foram: identificar as principais características da Sociedade PósIndustrial e suas influências nas transformações do mercado de trabalho; levantar as interferências dessas influências na captação de recursos humanos pelas empresas; identificar as principais competências pessoais e profissionais requeridas pelas empresas em sua política de recrutamento e seleção de candidatos; investigar se os programas de estágios e de recém-formados são utilizados pelas empresas conveniadas ao CIEE como captação de seus futuros profissionais. Buscou-se no referencial teórico estudar e analisar as características da sociedade, desde o período pré-industrial até o pós-industrial, delimitadas por Daniel Bell apud De Masi (1999:49). Através de subcapítulos foram selecionadas as características que poderiam corroborar na identificação da influência dessas transformações de forma a aprofundá-las com outros autores, como: as instituições básicas; os recursos principais; a estrutura profissional; o local típico; e o fator de mobilidade. No referencial teórico investigaram-se, ainda, alguns elementos da "sociedade centrada no mercado" tratada por alguns teóricos. Através das demandas de vagas do CIEE para estagiários e recém-formados identificou-se elementos da sociedade pós-industrial para confrontá-los com as competências exigidas. A metodologia utilizada foi quanto aos fins, estudo de caso, descritiva e explicativa, analisando as demandas das competências exigidas dos profissionais, estagiários, recém-formados através das empresas conveniadas ao CIEE. Quanto aos meios, foram realizadas pesquisas bibliográficas, documentais e telematizada, bem como uma pesquisa de campo para coleta de dados através de questionários e de entrevistas individuais aplicados ao público atendido pelo CIEE. O universo da pesquisa foi de empresas privadas e de grande porte. A amostra foi selecionada a partir da estratificação em sete regiões metropolitanas do Brasil, onde também encontram-se unidades do CIEE, cujas cidades apresentam o maior percentual de emprego formal no país, tendo como fonte a Geografia de Mercado. A amostra foi por acessibilidade e por tipicidade, em função do caso CIEE, totalizando 400 pessoas entrevistadas. O trabalho obteve como resultado a identificação de elementos das transformações do mercado de trabalho, à luz da sociedade pós-industrial, tal como o previsto por Bell apud De Masi, evidenciando que as empresas estão contratando estagiários e recém-formados com o mesmo nível de exigência quando da contratação de profissionais. As habilidades comportamentais (atitudes) identificadas neste estudo denotam uma forte tendência das empresas, à luz da razão substantiva, de exigir de seus recursos humanos competências tais como: iniciativa, criatividade, dinamismo, bom relacionamento interpessoal e facilidade para trabalhar em equipe, sendo pré-requisitos complementares à formação acadêmica.
