The Impact

The issue of animal welfare, particularly in relation to legislation, involves philosophical, ethical, economic and political issues and is not just a matter for science. A scientific definition of welfare must address the concerns of the public, but is difficult to achieve because of a lack of consensus as to what good welfare involves. The assessment of animal welfare is best achieved using a mixture of design criteria (which specify what must be included in the environment) and performance criteria (which specify what the signs of good welfare are). The quality of stockmanship can have a major influence on animal welfare, and it should not be assumed that the method of housing is the major determinant of animal welfare. The validity of many of the proposed measures of welfare is difficult to determine because of a lack of understanding of the underlying biology. Measures of aversion are the best available measures of animal suffering caused by procedures of short duration, but whether they can be used to assess the effect of housing is uncertain. Consensus has not yet been reached on the issue of behavioral deprivation, but several measures of behavioral motivation can be used to determine if animals are frustrated, although none is free from criticism. Much abnormal, stereotyped behavior seems to reflect feeding rather than housing problems, and there is a lack of firm evidence that the level of stereotypic behavior correlates with the welfare of the animals. The method of housing can influence the animals' physiology, but this effect is not adequately described by measures of corticosteroids. Use of the term "stress" generates confusion. Production measures give some information about animal welfare but only if the causes of lowered production are known. Animal welfare is a complex phenomenon and one component of welfare should not be equated with the whole, nor should scientific assessment of welfare be considered a simple matter. Key words: Animal welfare, aversion, motivation, abnormal behavior, stress, stockmanship

The Ideal

The ideal animal model would contribute no confounding variables in experimental science. Variables affect experimental design resulting in increased animal use or repeated studies. We demonstrated a simple refinement which may reduce the number of animals used experimentally while simultaneously improving animal welfare. The objective of this study was to determine if the presence of a hut was an impact on physiological stress levels, as determined by faecal cortisol concentration, during a routine four-day acclimatization period of newly received male Hartley-Outbred guineapigs. We hypothesized that those animals provided with huts would have decreased physiological stress compared with animals not provided with huts. We examined this effect within both paired and single-housed animals. A between-subjects one-way analysis of variance revealed that pair-housed animals with a hut had significantly lower faecal cortisol concentration than pair-housed animals without a hut and the presence and absence of a hut had no significant impact on faecal cortisol concentration in single-housed animals. These findings show that presence of a hut is beneficial in reducing physiological stress when pair housing male guineapigs and does not appear to have an impact when single housing male guineapigs. In addition, we have shown that faecal cortisol, and therefore physiological stress, is still increasing on study day 4 suggesting a longer acclimatization period is necessary. A simple refinement in housing environment and acclimatization time can both reduce the number of animals used experimentally and improve animal welfare.

The Impact

Substantial resources have been dedicated to designing and implementing training courses that focus on enhancing the interviewing skills of police officers. Laboratory research studies and real-world assessments of the effectiveness of interview training courses, however, have found notably mixed results. In this article, empirical studies ( N = 30) that have assessed the effectiveness of police interview and interrogation training courses were systematically reviewed. We found a wide variation in terms of the type, length, and content of the training courses, the performance criteria used to assess the training effectiveness, and the impact of the training courses on interviewing performance. Overall, the studies found that basic interviewing skills can be developed to a certain level through even short evidence-based training courses. More cognitively demanding skills, such as question selection and meaningful rapport-building, showed less of an improvement post training. The courses that included multiple training sessions showed the most consistent impact on interviewing behavior. This review also indicated a need for more systematic research on training effectiveness with more uniform and longer-term measures of effectiveness. Our findings should help guide future research on this specific topic and inform the training strategies of law enforcement and other investigatory organizations.

Physical Manipulation

The use of wild animals as photo props is prevalent across the globe and is widely recognised to represent a potential animal welfare concern. However, detailed information regarding the specific impacts of such activity on wild animal behaviour is currently lacking. Herein, we investigated how brown-throated three-toed sloths (Bradypus variegatus) were handled by tourists, and how sloths behaved during wildlife ‘selfies’ taken in Manaus, Brazil and Puerto Alegria and Iquitos in Peru. In total, we observed 17 sloths (during 70 focal observations) that were provided for use in wildlife selfies on 34 different tours. We found that an average number of 5 people held each sloth during each focal observation. For 48.6% of the time the sloths were handled in a way which involved physical manipulation of the sloths’ head and/or limbs and/or being held by the claws. From the eight different types of sloth behaviour observed, we found that the two types performed for the longest average duration of time were surveillance (55.3%) and limb stretching (12.6%). Our findings show that when being handled sloths were frequently held in ways that may compromise their welfare. Although to date the behaviour of sloths while being handled has not been reported in any published literature, in this study we document certain behaviours which may act as indicators of compromised welfare. We suggest that our data provides a potential baseline for future study into the behaviour and welfare of sloths.

The ACR-1000™ design is an evolutionary advancement of the proven CANDU® reactor design that delivers enhanced economic performance, safety, operability and maintainability. The fuel for the ACR-1000 design is based on the well established CANDU fuel bundle design that has over 40 years of demonstrated high performance. Building on its extensive experience in fuel design and analysis, and fuel testing, AECL has designed a CANFLEX-ACR™ fuel bundle that incorporates the latest improvements in CANDU fuel bundle design. The ACR-1000 fuel bundle also includes features that enable the ACR-1000 to achieve higher fuel burn-up and improved reactor core physics characteristics. To verify that the CANFLEX-ACR fuel bundle design will meet and exceed all design requirements, an extensive program of design analysis and testing is being carried out. This program rigorously evaluates the ability of the fuel design to meet all design and performance criteria and particularly those related to fuel failure limits. The design analyses address all of the phenomena that affect the fuel during its residence in the reactor core. Analysis is performed using a suite of computer codes that are used to evaluate the temperatures, deformations, stresses and strains experienced by the fuel bundle during its residence in the reactor core. These analyses take into account the impact of fuel power history and core residence time. Complementing the analyses, testing is performed to demonstrate the compatibility of the fuel with the reactor heat transport system and fuel handling systems, and to demonstrate the ability of the fuel to withstand the mechanical forces that it will experience during its residence in the core. The testing program includes direct measurement of prototype fuel element and fuel bundle properties and performance limits. A number of different test facilities are used including a cold test loop and a hot test loop with a full-scale ACR-1000 fuel channel that operates at reactor coolant temperatures, pressures and flows. This paper summarizes the out-reactor test program and related analysis that provide the basis for verifying that the ACR-1000 fuel design meets its requirements.

PurposeThis paper explores how a firm's public stand on a social-political issue can be a salient signal of the firm's values, identity and reputation. In particular, it investigates how boycott participation–conceptualized as a cue of a corporation's stand on important social-political issues–may affect the stock market valuation of that corporation, as well as how corporations legitimise their stand on the issues.Design/methodology/approachThe authors employ a mixed-methods design that uses both qualitative techniques (content analysis) and quantitative methods (event study methodology) to examine a sample of US firms who participated in a boycott campaign that sought to call attention to issues of hate speech, misinformation and discriminatory content on social media platform Facebook.FindingsFindings from the qualitative content analysis of company statements show that firms legitimise their stand on, and participation in, the boycott by expressing altruistic values and suggesting to stakeholders that their stand aligns not only with organizational values/convictions but also with the greater social good. Importantly, the event study results show that firms who publicly announced their intention to participate in the boycott, on average, earn a statistically significant positive abnormal stock return of 2.68% in the four days immediately after their announcements.Research limitations/implicationsFindings relate to a specific case of a boycott campaign. Also, the sample size is limited and restricted to US stocks. The signalling value of corporate social advocacy actions may vary across countries due to institutional and cultural differences. Market reaction may also be different for issues that are more charged than the ones examined in this study. Therefore, future research might investigate other markets, use larger sample sizes and consider a broader range of social-political issues.Practical implicationsThe presence of significant stock price changes for firms that publicly announced their decision to side with activists on the issue of hate propaganda and misinformation offers potentially valuable insights on the timing of trades for investors and arbitrageurs. Insights from the study also provide a practical resource that can be used to inform organizations' decision-making about such issues.Social implicationsTaking the lead to push on social-political issues, such as hate propaganda, discrimination, among others, and communicating their stands in a way that speaks to their values and identity, could be rewarding for companies.Originality/valueThis study provides novel evidence on the impact that corporate stances on important social-political issues can have on stock market valuation of firms and therefore extends the existing related research which until now has focused on the impact on consumer purchasing intent and brand loyalty.

The purpose of this study was to examine the opinions of school principals and teachers about the new implication process which teachers are being evaluated by school principals according to performance criteria. Phenomenological study design was chosen in this qualitative research. Participants were selected according to maximum variation sampling which is one of the purposeful sampling methods. Data were collected from 11 school principals and 14 teachers via semi-structured interview forms in Tokat city center. Data were analyzed according to descriptive analyzing technique. According to the results obtained in the study, participants stated that the purpose of current performance evaluation is the evaluation of teachers and to support their professional development. About the new application’s access to the purposes, while many of the teachers reported that the system could not achieve its goals, most of the school principals stated that the system would reach the goals with some shortcomings. Participants criticized the system for fast coming up and implementation. Participants stated that school principals were not qualified for this system. The most important strength of the system was defined as the teacher’s close awareness of the school principals. According to teachers’ views about the weaknesses of the system; the impact of conflicts or prejudices affecting school, school principals’ failure to take into account the criteria list, the existence of biased behaviors, the fact that principals were not educated in supervision, erroneous or incomplete practices in branch-specific evaluations, the deterioration of organizational peace. The majority of school principals reported that the applied system could contribute to the professional development of teachers, while the majority of teachers thought that the system would make a limited contribution. A two-day seminar was held with the school principals while training for teachers was not arranged by the Ministry of Education prior to the performance evaluation process. In the study, some suggestions were also made regarding the development of the current practice and the assessment of teacher performance in Turkey.Extended English abstract is in the end of PDF (TURKISH) file. ÖzetBu çalışmanın amacı öğretmenlerin performans kriterlerine göre okul müdürleri tarafından değerlendirildiği yeni uygulama konusunda okul müdürleri ve öğretmenlerin görüşlerini ortaya koymaktır. Nitel araştırma yöntemine göre tasarlanan bu çalışmada olgu bilim deseni benimsenmiştir. Çalışmada katılımcılar amaçlı örnekleme yöntemlerinden maksimum çeşitlemeye göre oluşturulmuştur. Tokat il merkezinde görev yapmakta olan 11 okul müdürü ve 14 öğretmenle yarı yapılandırılmış görüşme formu kullanılarak veri toplanmıştır. Veriler betimsel analiz tekniğine göre çözümlenmiştir. Araştırmada elde edilen verilere göre katılımcılar mevcut performans değerlendirme uygulamasının amacının daha çok öğretmenlerin değerlendirilmesi ve mesleki gelişimlerini artırma olduğu yönünde görüş belirtmişlerdir. Yeni uygulamanın amacına ulaşabilmesine ilişkin öğretmenlerin çoğunluğu sistemin amacını gerçekleştiremeyeceğini düşünürken okul müdürlerinin çoğunluğu bazı eksiklikler belirtmekle birlikte sistemin amacına ulaşabileceğini ifade etmektedirler. Uygulanma süreciyle ilgili katılımcılar sistemin bir anda gündeme gelmesi ve uygulanmasını eleştirmektedir. Katılımcılar okul müdürlerinin bu konuda yeterli olmadığını düşünmektedir. Sisteminin en önemli güçlü yanının okul müdürünün öğretmeni yakından tanıması olduğu ifade edilmiştir. Sistemin zayıf yönleri ile ilgili olarak öğretmenler; okulda yaşanacak çatışmaların veya önyargıların değerlendirmeyi etkilemesi, okul müdürlerinin kriter listesini dikkate almaması, taraflı davranışların varlığı, müdürlerin denetim konusunda eğitimli olmamaları, branşa özgü değerlendirmelerde hatalı veya eksik uygulama, örgüt barışının bozulması şeklinde görüş belirtmişlerdir. Okul müdürlerinin çoğunluğu uygulanmakta olan sistemin öğretmenlerin mesleki gelişimine katkı sağlayacağını belirtirken öğretmenlerin çoğunluğu kısıtlı katkı sağlayacağını düşünmektedir. Performans değerlendirme süreci öncesinde Milli Eğitim Bakanlığı tarafından öğretmenlere yönelik bir eğitim düzenlenmezken, okul müdürlerine iki günlük bir seminer düzenlenmiştir. Çalışmada ayrıca mevcut uygulamanın geliştirilmesi ile ilgili ve Türkiye’de genel anlamda öğretmen performansının değerlendirilmesi ile ilgili olarak birtakım önerilerde bulunulmuştur.

This article forecasts quite dramatic increases in the general population of the globe, which will also be reflected in increasing ageing populations. This paper explores how globalization and its structural economic and social forces throws into flux the policies and practices of individual nation states to address social, economic and political issues for older people focusing on empirical data on pensions and health and social care. The paper will examine specific empirical areas of populational projections across the world before we discuss some of the key challenges and consequences of global ageing for the study of ageing populations. It highlights how empirical research needs to move from being state centred to one of which acknowledges global forces and the impact of populational ageing.

Abstract A ban on seal product for animal welfare concerns had been adopted by the EU Parliament in 2009. This article examines whether the ban can be contested on the grounds of its effect on indigenous rights. It will first be determined whether the directive encroaches on the rights of indigenous peoples, as proclaimed by the UN Declaration. Despite the clause that exempts the purchasing of seal products, of which the Inuit are benefactors of; it is still believed that the Declaration has been breached, and thus constitutes a violation of their cultural and economic rights. The second section examines how the Inuit have challenged the Directive Regulation on Seal product. Overall, through the examination of this case, the goal of this article is to highlight the legal challenges facing Europe vis-à-vis the development of indigenous peoples’ rights.
