Evaluación de la involución, salud uterina y retorno de la actividad ovárica con la adición de zeolita 2% en la dieta basal de vacas lecheras

El objetivo de esta investigación fue evaluar el efecto de zeolita (Clinoptilolita) adicionado en la dieta basal de vacas lecheras durante 105 días, 60 días pre-parto (dap) y 45 días post-parto (dpp) y su influencia en la involución (IU) y salud uterina (SU), el retorno de la actividad ovárica (AO) y la condición corporal (CC). El proyecto se realizó en tres ganaderías de la comunidad de Soldados del Cantón Cuenca – Azuay, en 50 vacas secas, con una CC ≥ 3,5, entre 2 a 5 partos, clínicamente sanas y todas en las mismas condiciones sanitarias y de manejo; fueron divididas en un grupo control (n1=25), alimentadas con dieta basal y un experimental (n2=25), con dieta basal + 2% de Zeolita del consumo de materia (CMS). Se evaluó retorno de AO considerando folículos ≥ 10 mm de diámetro a los 15, 22, 35 y 45 dpp por Ultrasonografía transrectal, SU (>10 PMN) a los 35 dpp por cytobrush, IU considerando posición del útero con respecto a la pelvis (PU), simetría de los cuernos (SCU), y diámetro del cérvix (DC), a los 22 y 45 dpp por palpación rectal, y finalmente la CC a los 15 dap, parto y 45 dpp. Se usó un diseño completamente al azar (DCA) y los resultados fueron analizados con el programa estadístico SPSS versión 22.0, posteriormente fueron aplicados los estadísticos de “U de Mann Withney y Kruscall Wallis”. Se obtuvo eficacia en el GE con mayor porcentaje de vacas que retornaron su AO (respectivamente, para GC y GE fueron: 35 dpp 29,6% vs. 70,4%; 45 dpp 44,4% vs. 55,6%; p<0,05). La IU fue a los 45 dpp, los valores obtenido para GC y GE fueron: respectivamente, PU 40,0% vs. 76,0%, SCU 32,0% vs. 76,0% y DC 28,0% vs. 68,0%, (p<0,05). Y en SU también mostró eficacia en el GE obteniendo un 3,4% vs. 22,2% de PMN en comparación con el GC, (p<0,05). Finalmente, se comprobó diferencias significativas (p<0,05) en la CC al parto y 45 dpp con eficacia atribuida al GE. En conclusión, la adición de zeolita al 2% en la dieta basal mostró eficacia en la involución y salud uterina, retorno de la actividad ovárica y la condición corporal en vacas en transición, recomendando su uso en las ganaderías lecheras

Three Essays on Dual-Class Stock Structure

Dual-class stock structure is characterized by the separation of voting rights and cash flow rights. The departure from a common “one share-one vote” configuration creates ideal conditions for conflicts of interest and agency problems between controlling insiders (the holders of voting rights) and remaining shareholders. The owners of voting rights have the opportunity to extract private benefits and act in their personal interest; as a result, dual-class firms are often perceived to have low transparency and high information asymmetry. This dissertation investigates the quality of information and the information environment of firms with two classes of stock. The first essay examines the quality of information by studying accruals in dual-class firms in comparison to firms with only one class of stock. The results suggest that the quality of accruals is better in dual-class firms than in single-class firms. In addition, the difference in the quality of accruals between firms that abolish their dual-class share structure by unification and singe-class firms disappears in the post-unification period. The second essay investigates the earnings informativeness of dual-class firms by examining the explanatory power of earnings for returns. The results indicate that the earnings informativeness is lower for dual-class firms as compared to single-class firms. Earnings informativeness improves in firms that unify their shares. The third essay compares the level of information asymmetry between dual-class firms and single-class firms. It is documented that the information environment for dual-class firms is worse than for single-class firms. Also, the finding suggests that the difference in information environment between dual-class firms and single-class firms disappears after dual-class stock unification.

TAKING ORGANIZATIONS SERIOUSLY: RESPONSIBLE AGENCY, ORGANIZATIONS AND THE CRIMINAL LAW

In the post-Enlightenment period, Anglo-American criminal law has been applied with increased force, and an ever expanding scope, to collective actors like corporations and other organizations. Recent scholarship has focused on developing “truly organizational” bases of liability that break with the conventional approach of imputing individual conduct to an organization and instead analyze culpable conduct and intent in a way that reflects the distinct and independent capacity of organizations to pursue their interests or goals collaboratively. In 2004, Canada enacted amendments inspired by these ideas in the hope they would lead to more effective criminal enforcement against organizations. Twelve years later, however, the promise of Bill C-45 is largely unfulfilled. In this thesis, I explore how much of this failure of law reform to deliver transformational change is attributable to an individualist bias that permeates how we think about what it means to be responsible and how this then shapes the responsibility ascription process. Using an analytical framework that combines criminal law theory with selected aspects of rational-structural theory and organization culture, I suggest that a promising way forward may lie in reframing the essential qualities required to be a subject of the criminal law in a way that captures the unique attributes that make organizations different from individuals. The resulting organizational concept of responsible agency allows for an integration of organizational reality into how we assess organizational culpability while keeping the ambit of criminal liability within the limits of what is practicable and fair. This better aligns with the spirit of Bill C-45: to impose criminal liability in a way that takes organizations – and their crimes – seriously.

The EU referendum in Northern Ireland: closing borders, re-opening border debates

The UK decision to leave the European Union (EU) following a referendum in June 2016 fundamentally alters the country's relationship with the EU, with its European neighbours, with the rest of the world and potentially with its own constituent units. It is clear that different parts of the UK will be impacted differently by this decision and by the unfolding exit terms and process. In this context, Northern Ireland is considered to be particularly vulnerable. This article examines the referendum campaign in Northern Ireland by detailing input from the Northern Ireland administration, political parties, civil society and external figures. The article suggests that the overall referendum campaign in Northern Ireland was hamstrung by the opposing positions taken by key political protagonists, particularly Sinn Féin and the Democratic Unionist Party (DUP). This produced a challenging context for the referendum debate in Northern Ireland. The post-referendum period has also been marked by persistent differences in relation to how best to approach specific Northern Ireland issues and challenges. A continued absence of clear positions and a lack of contingency planning underline a poor level of preparedness for future political developments.

The 'Arc of prosperity' revisited: Homelessness policy change in north western Europe

This paper compares continuity and change in homelessness policy in Ireland, Scotland and Norway with a particular focus on the period of post-crisis austerity measures (2008-2016). The analytical approach draws on institutional theory and the notion of path dependency, which has rarely been applied to comparative homelessness research. The paper compares welfare and housing systems in the three countries prior to presenting a detailed analysis of the conceptualisation and measurement of homelessness; the institutions which address homelessness; and the evidence of change in the post-2008 period. The analysis demonstrates that challenges remain in comparing the nature of homelessness and policy responses across nation states, even where they have a number of similar characteristics, and despite some EU influence towards homelessness policy convergence. Similarly, national-level homelessness policy change could not be interpreted as entirely a result of the external shock of the 2008 general financial crisis, as existing national policy goals and programmes were also influential. Overall, embedded national frameworks and institutions were resilient, but sufficiently flexible to deliver longer term policy shifts in response to the changing nature of the homelessness problem and national policy goals. Institutionalism and path dependency were found to be useful in developing the comparative analysis of homelessness policy change and could be fruitfully applied in future longitudinal, empirical research across a wider range of countries.

The Power of the Synthetic Control Method

The synthetic control method (SCM) is a new, popular method developed for the purpose of estimating the effect of an intervention when only one single unit has been exposed. Other similar, unexposed units are combined into a synthetic control unit intended to mimic the evolution in the exposed unit, had it not been subject to exposure. As the inference relies on only a single observational unit, the statistical inferential issue is a challenge. In this paper, we examine the statistical properties of the estimator, study a number of features potentially yielding uncertainty in the estimator, discuss the rationale for statistical inference in relation to SCM, and provide a Web-app for researchers to aid in their decision of whether SCM is powerful for a specific case study. We conclude that SCM is powerful with a limited number of controls in the donor pool and a fairly short pre-intervention time period. This holds as long as the parameter of interest is a parametric specification of the intervention effect, and the duration of post-intervention period is reasonably long, and the fit of the synthetic control unit to the exposed unit in the pre-intervention period is good.

Gender, class and the household economy in Scotland in the ‘Age of affluence’

From early 1950s to the early 1970s Britain is said to have experienced an ‘age of affluence’. Whilst material conditions for many households improved in these decades, this detailed examination of budget management processes shows that for many working-class households, these gains were the product of hard work and careful money management. Using oral history methodology, this thesis explores lived experiences of the household economy to illuminate these qualifications to ‘affluence’. In so doing, this thesis advances analysis which considers the relationship between the macro-level economic conditions of affluence and the everyday economic realities of households in the post-war period. The thesis examines the operation of the household economy and shows how working-class households utilised domestic labour, budgeting, paid work, credit and thrift to make ends meet, as well as to achieve ‘affluence’. Further, by exploring these areas of the household economy, this thesis shows that gendered ideology continued to preserve power and material inequalities between men and women. Although considerable change did occur, particularly involvement in the paid labour market, domestic responsibilities continued to be an important focus of women’s identities and the effective performance of these duties by women remained central to the success of the household. This thesis represents a fresh focus on how the exploration of everyday life, including the salience of ideological continuities in shaping experience, can qualify and refine our understanding of twentieth century economic and social change, and contributes to socio-historical understandings of ‘affluence’ and its intersections with the household, gender, and class.

Experimental Study of the Earthquake Recurrence Period and the Trend of Post-Seismic Development

In order to study the earthquake recurrence and the characteristics of earthquake series, rupture tests of rock samples and plexiglass samples were made. On rock samples, a number of acoustic emission (AE) and strain measuring points were deployed; the load was one side direct shear. The variation characteristics of AE and strain at different detecting points around the extra large fracture were observed and studied. On plexiglass samples, a series of inclined cracks were prefabricated by a small-scale compressive testing machine. The samples were then loaded on a shockproof platen, when the samples were loaded, the stress intensity factor (SIF) was determined by the laser interferometric technique and shadow optical method of caustics. The fracture conditions such as material toughness around the extra large fracture were also studied. From those experimental results and the theory of fracture mechanics, the earthquake recurrence period and the trend of post-seismic development were studied.

Attitudes to community relations in Northern Ireland: signs of optimisim in the post-cease fire period?

This article uses attitudinal data to explore Catholic and Protestant perspectives on community relations and equality since the paramilitary cease fires in 1994. Although attitudes tend to fluctuate with the‘headline grabbing'events of the day, the article argues that there are signs that some fundamental changes have taken place in the post cease fire period. Of particular importance in this regard is the positive response recorded by the Catholic community towards government measures to tackle disadvantage and inequality. Equally significant is the protestant response to many of these measures which is often one of ambivalence rather than derision. In so far as the data appear to challenge the‘zero-sum'game that traditionally underpins relations between the two communities in Northern Ireland, they provide some grounds for optimism. Yet such optimism is tempered somewhat by the seeds of discontent which are manifest within the protestant community, particularly around issues of equality in employment and cultural traditions. Despite the more positive assessment of community relations and equality in 2002, it is argued that further monitoring will be required to determine the long-term effects of policy reform on relationships between the two communit

Left ventricular free wall impeding rupture in post-myocardial infarction period diagnosed by myocardial contrast echocardiography: Case report

Abstract Background: Left ventricular free wall rupture occurs in up to 10% of the in-hospital deaths following myocardial infarction. It is mainly associated with posterolateral myocardial infarction and its antemortem diagnosis is rarely made. Contrast echocardiography has been increasingly used for the evaluation of myocardial perfusion in patients with acute myocardial infarction, with important prognostic implications. In this case, we reported its use for the detection of a mechanical complication following myocardial infarction. Case presentation: A 50-year-old man with acute myocardial infarction in the lateral wall underwent myocardial contrast echocardiography for the evaluation of myocardial perfusion in the third day post-infarction. A perfusion defect was detected in lateral and inferior walls as well as the presence of contrast extrusion from the left ventricular cavity into the myocardium, forming a serpiginous duct extending from the endocardium to the epicardial region of the lateral wall, without communication with the pericardial space. Magnetic resonance imaging confirmed the diagnosis of impending rupture of the left ventricular free wall. While waiting for cardiac surgery, patient presented with cardiogenic shock and died. Anatomopathological findings were consistent with acute myocardial infarction in the lateral wall and a left ventricular free wall rupture at the infarct site. Conclusion: This case illustrates the early diagnosis of left ventricular free wall rupture by contrast echocardiography. Due to its ability to be performed at bedside this modality of imaging has the potential to identify this catastrophic condition in patients with acute myocardial infarction and help to treat these patients with emergent surgery.
